Title: Optical encoder
Inventor: FUKUDA TAKUMI
IPC: G01D5/36
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To double the resolution of an optical encoder. SOLUTION: An optical encoder is provided with a moving plate 1 which passes through first and second areas A and B, a light source 2 which is counterposed to the area A on the lower surface side of the plate 1, a light receiving element 3 which is counterposed to the area B on the lower surface side of the plate 1, and a light projecting means 4 which is interposed between the areas A and B on the upper surface side of the plate 1. The plate 1 is provided with slits 5 which are arranged at regular pitches along the moving direction of the plate 1 in which the areas A and B are connected to each other. The light source 2 forms the image of the slits by emitting light upon the slits 5 while the slits 5 pass through the area A. The projecting means 4 transforms the image of the slits into an unmagnified inverted real image and projects the real image upon the second area B.  The optical system constituted in such a way contains an objective lens 6 faced to the first area A, an image forming lens 7 faced to the second area A, and a relay lens 15 provided between the lenses 6 and 7. The light receiving element 3 receives the real image of the slits 5 which move in the opposite direction by using the slits 5 passing through the area B as a mask and detects the displacement of the moving plate 1.

IPC: B23B31/117
Filed: 1985-12-28
Abstract: PURPOSE:To provide possibility to change torque for clamping by interposing a clutch between the axis of the body and a tool, and by providing adjustability for the friction force of said clutch using the amount of motion of the axis in the axial direction. CONSTITUTION:When a chuck is installed, a processing spindle makes processing while a clamping tool 101 is fitted as it is, and that part of a tool 117 which is in the form of a square wrench fits on a square shaft 129 of a control shaft 128, to be followed by sinking a little. Now the downward oriented force of the processing spindle is given to a friction plate 112 between a contact part 111 and a ring 106 through the action of a coil spring 110. If in this condition the processing spindle rotates, the rotation is transmitted to the tool 117 through the axis 104, key 118, contact part 111, friction plate 112 and ring 106. The tool 117 rotates the control shaft 128 with its frictional torque to move a movable clamping element 137 in the direction of fastening a work 45a.

Title: Power converter
Inventor: SATO KAZUHIRO
IPC: H02M1/00
Filed: 1994-12-02
Abstract: PURPOSE: To enhance the cooling efficiency of a heating element by fixing a heat pipe for heat dissipation with a power board. CONSTITUTION: A positive pole conductive plate 7P, an AC conductive plate 7A and a negative pole conductive plate 7N are inserted into a tubular heat pipe 101 and fixed thereto. The heat pipe 101 is elongated sufficiently at the part thereof exposed from the end faces of the conductive plates 7P, 7A and 7N so that the heat dissipating part, i.e., the upper part, thereof projects to the outside from a power board 10. Consequently, the heat filled in the space and the heat of the conductive plates are dissipated effectively through the heat pipe 101 and a package is cooled efficiently. Since the heat of a snubber resistor within the package 6 is also dissipated effectively through the function of the heat pipe 101, the snubber resistor does not require a significantly high capacity.

Title: Sheet for scorching foodstuff by microwave heating
Inventor: MATSUMOTO NOBUYOSHI
IPC: F24C7/02
Filed: 1987-11-27
Abstract: PURPOSE:To reliably scorch the surface of frozen foodstuff or foodstuff containing much moisture by placing the foodstuff on a sheet which comprises two layers of metals having different electrical resistances, the layers being sticked together with an insulating layer therebetween, and then by radiating microwaves to the foodstuff. CONSTITUTION:An aluminum deposited film 4 is formed by applying an aluminum layer 2 on one side of an insulating layer 3 by vacuum evaporation and sticking another insulating layer 3' to sandwich the aluminum layer 2. A stainless steel deposited film 6 is formed by applying a stainless steel layer 5 on one side of an insulating layer 7 by vacuum evaporation and sticking another insulating layer 7' on the stainless steel layer 5. Both of them are glued together to make up a sheet 1 with an insulating adhesive layer 8 therebetween. Since the sheet 1 has two metal layers having different electrical resistances with the insulating layer therebetween, the heat generating effect by the microwave radiation is significantly improved. Further, since there occurs no sparks which may damage the foodstuff, the scorching can be reliably applied to the surface of the foodstuff even if it is frozen or contains much moisture.

IPC: G01R19/04
Filed: 1987-11-27
Abstract: PURPOSE:To precisely detect a peak voltage of an input signal during a period settled freely by charging and holding the peak value of the input signal to a capacitor only while a gate signal is inputted. CONSTITUTION:While the gate signal is H (plus logic), a switch 3 is turned to 'close', on comparing the input signal with an output signal, as far as a state wherein the input signal is lower than the output signal is continued, a capacitor 4 is charged driving a constant current source 2. And on coinciding, the charging is stopped, by contraries even in case the input signal becomes low voltage, a charging electric charge of the capacitor is kept so as to be constant on the output voltage, accordingly the peak voltage is kept. When the gate signal is turned to L (minus logic), the switch 3 is turned to 'open' and an action as for a peak detection circuit is stopped. On the other hand a reset circuit 7, regardless of the gate signal, lets the charging electric charge of the capacitor 4 discharge at a constant period.
