摘要： A method of manufacturing an optical waveguide includes: forming a first reflective bump and a second reflective bump, which have inclined surfaces formed on sides opposite to each other and which are disposed with a predetermined distance in-between, on an upper side of a conductive carrier; polishing the surfaces of the first reflective bump and the second reflective bump; forming a core between the first reflective bump and the second reflective bump; stacking an upper cladding over the upper side of the carrier to cover the first reflective bump, the second reflective bump, and the core; removing the carrier; and stacking a lower cladding over a lower side of the upper cladding. Forming reflective bumps on a conductive carrier, and polishing the reflective bumps to form inclined surfaces, can reduce lead time and can provide a high degree of freedom in design.

摘要： A casting roll moving apparatus for a twin roll type continuous strip casting process is disclosed. The casting roll moving apparatus is used with a twin roll type strip casting machine that produces a strip through a method in which, while high-temperature steel melt is supplied between twin rolls which rotate in opposite direction, a large amount of heat is dissipated through the rolls by contact between the steel melt and the rolls, so that the steel melt is rapidly solidified. Opposite ends of the rolls are automatically aligned, so that the recovery rate of the apparatus is increased, and a stable casting process is ensured. Because friction of the apparatus is markedly reduced so that an even rolling force is ensured, a gap between the rolls is maintained constant. Thus, the thickness of a cast strip is maintained constant, and the problem of the occurrence of an uneven surface pattern is solved.

摘要翻译： 公开了一种用于双辊式连续条带铸造工艺的铸辊移动装置。 铸辊移动装置与双辊式带式铸造机一起使用，该双辊式带式铸造机通过以下方法制造带材：通过在相反方向旋转的双辊之间供给高温钢熔体的同时，大量的热量通过 通过钢熔体和辊之间的接触使辊卷入，从而使钢熔体快速凝固。 辊的相对端自动对准，使得装置的回收率提高，并且确保了稳定的铸造工艺。 由于装置的摩擦力显着降低，因此确保均匀的轧制力，辊之间的间隙保持恒定。 因此，铸带的厚度保持恒定，解决了不均匀表面图案的发生的问题。

摘要： A synchronous switching regulator controller incorporates a switch detection circuit to determine the presence or absence of a power switch at the output of a switch driver so that the switch driver can be disabled when it is left unused. In one embodiment, the synchronous controller includes a switch detection circuit receiving a power cycle signal and the PWM ramp clock signal and measuring a voltage at an output node of the switch driver. The switch detection circuit provides a driver enable signal in response to the assertion of the power cycle signal. The driver enable signal has a first logical state when the voltage at the output node of the switch driver is greater than a reference voltage and a second logical state when the voltage at the output node is less than a reference voltage. The switch driver can be disabled based on the driver enable signal.
