蘋果用0.2毫米條形碼管控iPhone蓋板玻璃生産

9月30日消息，根据科技媒体 The Information 报道，苹果使用Tiny QR Code二维码蚀刻到iPhone 屏幕上，从而追踪供应商不合格屏幕的数量。報道稱每台iPhone屏幕上都有2個QR條形碼，其中一個條形碼位于屏幕內側邊框上，而另一個條形碼非常小，報道描述稱僅有0.2毫米。

苹果公司花费了数百万美元开发条形码系统，并在蓝思科技和伯恩光学两家公司安装了激光扫描设备，这两家公司主要负责为苹果生产iPhone 盖板玻璃。苹果通过条形码系统可以计算蓝思科技和伯恩光学生产的每块玻璃，并准确了解由于缺陷浪费了多少材料。在條形碼系統未實施之前，兩家公司每10塊蓋板玻璃中就有3塊被扔掉，在實施之後，供應商已經將浪費減少到10%。蘋果目前采用生産付費方式，降低錯誤率爲其節省了數億美元。

Mrs Keeling’s powers of intuition could make nothing of this. Starting with the firm conviction that Mr Silverdale had proposed to her daughter, there seemed no place where it would fit in. CHAPTER XIII. "At times," said Lieutenant Durand. "I shall be with you in a moment." "She has outgrown this work," I insisted. "But the streets and houses?" hazarded Allingham, "aren't they like ours?" Considered as means for transmitting power, the contrast as to advantages and disadvantages lies especially between belts and gearing instead of between belts and shafts. It is true in extreme cases, such as that cited at Crewe, or in conveying water-power from inaccessible places, through long distances, the comparison lies between belts and shafts; but in ordinary practice, especially for first movers, the problem as to mechanism for conveying power lies between belts and gear wheels. If experience in the use of belts was thorough, as it is in the case of gearing, and if the quality of belts did not form so important a part in the estimates, there would be but little difficulty in determining where belts should be employed and where gearing would be preferable. Belts are continually taking the place of gearing even in cases where, until quite recently, their use has been considered impracticable; one of the largest rolling mills in Pittsburg, Pennsylvania, except a single pair of spur wheels as the last movers at each train of rolls, is driven by belts throughout. By placing the axes of tangent gearing so that the threads or teeth of the pinions are parallel to the face of the driven teeth, [53] as in the planing machines of Messrs Wm. Sellers & Co., the conditions of operation are changed, and an interesting problem arises. The progressive or forward movement of the pinion teeth may be equal to the sliding movement between the surfaces; and an equally novel result is, that the sliding action is distributed over the whole breadth of the driven teeth. On that day I saw for the first time in Belgium German sailors and marines, and even an admiral and some officers. At that time the appearance of the naval men gave the newspapers much room for conjectures; it was found later that they were to be used in the attack on Antwerp, and afterwards had the task allotted to them of occupying the sea-board. V. prefer going to Sallie's, but Julia asked me first, so if I The Reverend Taylor gradually became aware that the air was very bad. He laid down the newspaper and looked round. The circumstance sank deeply into the mind of the king, and, resenting especially the conduct of Grenville—who had acted as though he held a monopoly of office,—he determined to be rid of him. He therefore consulted with his uncle, the Duke of Cumberland. That prince, to whom age and infirmities seemed to have given a degree of wisdom, declared the offer of the Ministry to Pitt to be the necessary step, and willingly undertook to make it. But knowing that Pitt would not even listen to the proposal without Temple, he dispatched a summons to Stowe for that nobleman, and himself, infirm as he was, went to Hayes, to learn the will of the great commoner personally. Pitt showed himself disposed to accept the office, on condition that general warrants should be declared illegal; that the officers dismissed on account of their votes be restored; and that an alliance with Protestant powers, and especially with Prussia, should be formed, to counterbalance the compact between France and Spain. This was asking a great deal; but Pitt demanded more in the particulars of appointments,[187] namely, that Pratt, who had opposed the Court so decidedly as regarded Wilkes and general warrants, should be Lord Chancellor, and he opposed the Court desire that the Duke of Northumberland should be at the head of the Treasury. Pitt, moreover, designed the Treasury for Temple. But, when Temple arrived, he refused to take office at all. The fact was that just now he was making a reconciliation with his brother, Grenville, and was averse from throwing him overboard. So far from joining Pitt, he was on the verge of another breach with him. Pitt, disconcerted by this repulse, with a weakness to be deplored in so great a man, refused to accept the offer to form a ministry at all. "Yes. Let's talk to the conductor and engineer." De Boteler, not caring to continue so uninteresting a subject, discoursed upon other matters; and the business of the morning having concluded, he retired with his guests from the hall. "My lord has heard from the steward that you are an honest tenant, and has directed that any alteration you may require in your tenement shall be attended to, and that the field which lies at the back of your dwelling be added to it without additional rent; and, as it gives me pleasure to encourage the industrious, in any request you may make, my interest shall not be wanting. And now, honest man," added she, with even more suavity, "my lord has a question to ask—it is but a simple inquiry, and I feel assured that a person of such strict probity will not evade it—know you Stephen Holgrave's place of concealment?" As she put the interrogatory, she looked earnestly in the smith's face. HoME yazhouqingsezaixianENTER NUMBET 008jieqiangtiffany.com.cn
