Title: Generating circuit for reference potential
Inventor: FURUYAMA TOORU
IPC: G11C11/407
Filed: 1981-11-04
Abstract: PURPOSE:To manufacture the reference potential generating circuit, in which the variation of substrate potential is absorbed by the capacitance change of a substrate  and a region having a conduction type reverse to the substrate and reference potential  outputted even when substrate potential varies does not change, by forming said reverse  conduction type region onto a polysilicon layer shaping a resistance element and the  substrate under an insulating layer and connecting the region to a ground circuit. CONSTITUTION:N<+> impurity diffusion regions 14a, 14b are formed onto the P type semiconductor substrate 11 while an N<+> ion implanted layer 15 is shaped between the regions 14a, 14b. The polycrystal polysilicon layer 13 is molded onto the ion implanted  layer 15 through the insulating layer 12, and the impurity diffusion regions 14a, 14b are  connected to the ground circuit. Here, capacitance C1 is one obtained by positioning  the insulating layer 12 between the polycrystal polysilicon layer 13 and the N type  region 15, and capacitance C2 is one generated among the N type regions 14a, 15, 14b and the P type substrate 11. When substrate potential VBB varies in such capacitance  relationship, capacitance C2 changes and the effect of the variation is all absorbed  because the depletion layer of a P-N junction among the N type regions 14a, 15, 14b  and the P type substrate expands and contracts.

Filed: 1999-06-23
Abstract: PROBLEM TO BE SOLVED: To keep the jet of a cleaning liquid almost uniform over the entire length of a nozzle by changing the size of an ejection opening of the nozzle to be larger on the cleaning liquid supply side and smaller on the tip side in the nozzle which is disposed approximately at the same height with the level of a cleaning tank and passes the cleaning liquid along the level. SOLUTION: In a cleaning tank 10, a cleaning liquid overflows from the notch 12 of an upper part opening 11, and the overflow liquid is received by an L-shaped receiver 13. A nozzle 16 is disposed at a position opposite to the notch 12 and generates a cleaning liquid flow on the level of the cleaning tank. The nozzle 16 is molded in the shape of a slender square cylinder, a lot of ejection openings 17 are bored longitudinally in one side surface, and a water supply pipe 18 is connected to one end part. The size of each ejection opening 17 is increased gradually on the side of the water supply pipe 18 and decreased gradually on the tip side. In this way, the ejection strength of the cleaning liquid ejected from each ejection opening 17 is kept nearly uniform over the entire length of the nozzle 17.

Title: Printed wiring board
Inventor: FURUKAWA MASANOBU
IPC: H05K3/00
Filed: 1987-07-16
Abstract: PURPOSE:To enable post-mounting components to be soldered easily on a printed wiring board on which circuit components have been mounted, by applying a first paint layer on the periphery of a mounting hole on the surface of the insulating board such that it is overhung over the hole and applying a second conductor layer over the first one so as to cover the end faces of the mounting hole. CONSTITUTION:A conducting circuit 2 is formed on the rear face of an insulating board 1 which is provided with mounting holes 3 through which leads 12 of circuit components 11 are inserted. A first paint layer 4 is applied on the periphery of the mounting hole 3 on the surface of the board 1 such that it is overhung over the hole 3. Further, a second paint layer 5 is applied over the first layer 4 so as to cover the end face of the mounting hole 3. Thereby, the mounting holes in which circuit components are not inserted in the first soldering process are prevented from being filled with solder when the first soldering process is carried out in a soldering bath. Accordingly, post-mounting components can be mounted easily without the need of secondary treatments such as removal of the solder from the mounting holes.

Title: Torque measuring instrument for motor
Inventor: HASHIMOTO ISAMU
IPC: G01L3/00
Filed: 1985-08-13
Abstract: PURPOSE:To measure accurate torque by making thread wound round a shaft of a motor follow the motion of the motor and eliminating influence by inertia of the thread and a plumb. CONSTITUTION:When a pulse train is impressed on the motor 9, the shaft 10 revolves in accordance with pulse frequency and the thread 4 wound round the shaft 10 several times rises from a stationary state. Accordingly, a movable body 1 and the plumb 8 which are connected with the thread applying tension to it are also moved vertically in accordance with the rotation of the shaft 10. In this case, since the thread 4 is always impressed with the tension, looseness of the thread 4 does not take place and the motions of the thread 4, the movable body 1, a bolt 6 and the plumb 8 are synchronized with the rotation of the shaft 10 at all times. Then, the adjustment of the tension of the thread 4 can be performed by drawing out the bolt 6 from the movable body 1 by the metal fittings 7 for adjustment. Further, since a position of the movable body 1 is regulated by a guide 2 in a stroke of the vertical movement, the fixed torque is impressed on the shaft 10. In this way, the static torque is always applied to the shaft by the thread, the movable body, the plumb, etc. and the accurate torque can be measured.
