Filed: 1987-09-22
Abstract: PURPOSE:To keep output voltage constant against temperature change on the periphery, by cancelling the lowering of its own Zener voltage in a Zener diode, forcibly with the increasing action of the Zener voltage due to a temperature compensating diode. CONSTITUTION:When an ambient temperature is heightened, then the Zener voltage of a Zener diode D2 is forced to be lowered because the diode D2 has negative temperature characteristic. However, a temperature compensating diode D3 has the negative temperature characteristic, and so its forward voltage is lowered, and its result, the Zener current IZ of the Zener diode D2 is increased, and the Zener voltage is forcibly increased. As its result, voltage drop component due to the temperature characteristic of the Zener diode D2 is to be cancelled with forcible voltage increase component due to the temperature compensating diode D3, and regardless of the temperature rise, its output voltage V0 is retained to come to a constant value. Also in case that the ambient temperature is lowered, a device is worked in the same manner.

Abstract: PURPOSE:To shorten the component supplying time and thereby to increase the productivity by a method wherein the attitude of an L-shaped component taken out from a component feeder is controlled by rotating it only twice, in the horizontal direction and in the vertical direction. CONSTITUTION:A corner section of the square-pillarlike material of a parts feeder 5 makes a receiving section 6 where an L-shaped component 1 is put, and the angle theta1 of a side of the corner section to a horizontal plane is 45 degrees. The component 1 is sent with the leads formed on one side facing backwards.

Title: Grinding wheel with inner peripheral cutting edge
Inventor: OTSUKI MAKOTO
IPC: B28D1/12
Filed: 1988-09-22
Abstract: PURPOSE:To well slice a semiconductor ingot by forming the thickness of the knife-edge side face at 1.0 piece part of abrasive grain and the edge width of an inner peripheral edge in 0.3-0.8mm. CONSTITUTION:The edge width of the edge face 2 of the inner periphery of an inner peripheral edge grindstone is taken in 0.3-0.8mm and a diamond abrasive grain 3 is electrodeposited in this zone. The edge thickness is taken as that of electrodepositing the abrasive grain one part to a base metal 4. So due to small edge width a chip reaches the base metal 4 immediately, and due to a thin base metal the chip is made free and discharged to the external part. So the friction resistance due to the chip clogging is remarkably reduced, the wafer crack and chip of the wafer slicing time become difficult to generate and slicing can be done well. Also due to the thin edge thickness the cutting allowance is reduced as well.
