Title: Photoelectric transducer and manufacture thereof
Inventor: SAITO TADASHI
IPC: H01L31/04
Filed: 1989-02-22
Abstract: PURPOSE:To sufficiently absorb incident light even when the thickness of the title transducer is reduced by a method wherein the transducer is constituted in such a way that the angle of a V-groove in the surface on the light-incident side is different from the angle of a V-groove in the rear. CONSTITUTION:V-grooves are formed in the surface 31 and the rear 41 of a photoelectric transducer 11; angles of the V-grooves formed in the surface 31 and the rear 41 are made different. Accordingly, the surface 31 and the rear 41 are tilted at a certain angle theta to each other; incident light 21 which has passed through the transducer is reflected by the rear 41 and is reflected toward inside by the surface 31 of the transducer. Especially when this angle thetais set to 3 deg. or larger, the light which has reached the rear 41 in the first operation is subjected to total reflection. When an angle theta1 is made different from an angle theta2, the light which has once been incident is confined to the inside of the substrate 11 and is absorbed efficiently.

Filed: 1993-03-02
Abstract: PURPOSE:To relieve the frictional resistance between a lead hole and a diode made in the solder assembling stage of the lead for correcting such troubles as defective separation of the title jig and the damage to the diode. CONSTITUTION:The gaps are to be made between lead holes 3, 5 and leads 8a, 8b due to the difference in thier diameters in the assembling stage as well as there is horizontal deviation between the lead holes 3 and 5 from each other. Besides, the frictional resistance is to be made between the lead holes 3, 5 and a diode 7 of the title jig by the leads 8a, 8b bending in (<) shape stretching themselves against the inner surfaces of the lead holes 3, 5 and an angle X. However, this frictional resistance is to be relieved by a slight movement S in the horizontal direction halfway in the title separating method. Because this separating method contains the first step L firstly lifting an upper jig 6 vertically by the least distance L and the second step S moving the upper jig 6 in the horizontal direction by the slight distance S. At this time, a weight 42 is lightly held to the diode 7 to be left intact on the lower jig 4 through the intermediary of the upper lead 8b.

Filed: 1989-02-21
Abstract: PURPOSE:To drive a rotary spring directly with voltage by sticking piezoelectric members expandable/contractable vertically to the loading direction of voltage upon loading of voltage onto a thin metal board and regulating the piezoelectric member. CONSTITUTION:Piezoelectric members 17, 18 are sticked onto the surface of a thin metal board having curvature comprising leaf springs 9, 10 and lead wires 19, 20 are connected with the piezoelectric members 17, 18. Voltage is previously loaded onto the piezoelectric members 17, 18 through lead wires 19, 20. Then the voltage to be loaded onto the piezoelectric member 17 through the lead wire 19 is reduced in order to contract the piezoelectric member 17. On the other hand, voltage to be applied onto the piezoelectric member 18 through the lead wire 20 is increased in order to expand the piezoelectric member 18. The leaf spring 9 flexes furthermore due to the difference of deformation of the piezoelectric members 17, 18 between the opposite faces of the thin metal board 16. Voltage is also regulated similarly for the leaf spring 10. Deformation of the leaf springs 9, 10 is converted into rotation in the direction of an arrow 21 based on the theory of lever employing the members 13, 14.

Title: Rotary grinding wheel
Inventor: TOGE NAOKI
IPC: B24D7/00
Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of the unpolished part without repeatedly making reciprocating motion while dislocating a locus of a rotary grinding wheel by forming grooves continuing in the circumferential direction so as to be dislocated from a concentric circle. SOLUTION: A rotary grinding wheel 10 is formed by fixing an abrasive material layer 13 to the surface of a plastic disk-shaped base so that spiral grooves 11 and a large number of radial grooves 12 turning to the outer peripheral part from a central hole 14 are formed in the abrasive material layer 13. A spiral shape is set so that the grooves do not exist at the same radial point separate by 180 degrees from a certain one point of these continuous spiral grooves 11. In the rotary grinding wheel 10, since the circumferential directional grooves 11 are formed in a spiral shape in this way, the spiral grooves 11 do not overlap in the circumferential direction when rotating the rotary grinding wheel 10, so that the abrasive material layer 13 contacts with the whole surface of the work object part to thereby prevent the occurrence of the linear unpolished part.
