Patent JP-H03282005-A (JP)
Title: Screw
Inventor: KOCHIYAMA SHIGERU
IPC: F16B23/00
Filed: 1990-03-29
Abstract: PURPOSE:To quickly remove dust generated when an automatic screw tightening machine for holding a screw by air sucking used, by making the head of the screw noncircular. CONSTITUTION:A screw 1 is guided by the suction sleeve 2 of an automatic screw tightening machine, and tightened by the bit 3 of a motor-driven screwdriver. Since the head of the screw 1 is noncircular as shown in Fig., and clearances exist between the sleeve 2 and the screw head, streams of airflow 4 constantly suck and remove fine dust continuously generated. A clean room cn thus be prevented from contamination.

Title: Machine breakage reducing device for nc lathe
Inventor: KUWABARA IWAO
IPC: B23Q11/00
Filed: 1989-03-31
Abstract: PURPOSE:To reduce the breakage due to the interference of a machine which is generated by the mistake in a program by limiting the driving current supplied into a servomotor so as to be less than a prescribed set value and controlling the motor so as to be driven always with a low torque, in the check of the working program for an NC lathe. CONSTITUTION:When a working program is checked by turning an operating switch 17, an electric current limit signal is outputted into an electric current limit circuit 20 by a servomotor low torque setting circuit 19, and even if the driving current outputted from a drive amplifying circuit 11 exceeds the electric current set by the electric current limit signal, the driving electric current is limited by an electric current limit circuit 20 so as to be equal to a set value. Therefore, when the switch 17 is in turned-ON state, independently of the driving current value outputted from the circuit 11, servomotors 3, 5, and 7 are always driven with a low torque, and even if the tool interference is generated in the check of the working program, the breakage of a machine is little, and the generation of the center deflection of a shaft is prevented.

Title: Tracking controller of recorded information reproducer
Inventor: ISO YOSHIMI
IPC: G11B7/085
Filed: 1982-05-19
Abstract: PURPOSE:To attain stable jumping control not affecting the position of an actuator, by applying an accelerating pulse to a reading means, receiving an output detecting a specific position, applying a decelerating pulse, closing a control loop after the end of application and performing the jumping control. CONSTITUTION:When a trigger pulse of a jump instruction is inputted to a jump instruction input terminal 21, an output of a D-FF18 goes to ''High'' and a switch 11 is closed. Further, an output of the FF18 is inputted to an addition/ subtraction amplifier 26 and applied to the actuator 14 as the accelerating pulse. When the actuator 14 comes to the center between tracks, since a pulse is generated from a specific position detector 17 between the tracks, a leading pulse is inputted to the clock input of the FF18 and a Q output goes to ''Low''. The output of a multivibrator 32 goes to ''High'' by the trailing of pulse, the output is applied to the input of the amplifier 26 while keeping the loop open, a pulse of the opposite polarity and the accelerating pulse are produced and the actuator 14 is driven in the decelerating direction and braked. The loop is turned on after the end and the jumping scanning is executed.

Title: Power circuit
Inventor: YASUMURA MASAYUKI
IPC: H04N5/46
Filed: 1985-04-18
Abstract: PURPOSE:To supply high power with small sizes without losing reliability by constituting the exciting circuits of the first and second insulated converter transformers with the first and second switching elements of push-pull operation. CONSTITUTION:The primary winding 13a and 31a of saturated reactor transformers 13 and 31 are excited by two switching transistors 80A and 80B which performs push-pull operation. This reduces excitation current compared to one switching transistor with no loss in the insulation converter transformers 13 and 31 by deviated excitation against larger load power. This results in no need for large sizes, smaller heating area because of low heating, and a smaller power block compared to the excitation of one switching transistor. This also reduces heating of the transformers 13 and 31, and causes not so much current in the transistors 80A and 80B and does not loose reliability.

Title: Semiconductor laser element
Inventor: YAMAMOTO SABUROU
IPC: H01S5/24
Filed: 1984-04-24
Abstract: PURPOSE:To contrive the improvement in manufacturing yield of the titled element of hetero junction type and in reliability of characteristics by a method wherein a groove is formed in a substrate on which multilayer crystals are laminated. CONSTITUTION:After the grown surface of a crystal layer 8 is flattened by filling the groove 7 formed in the crystal growing substrate 1 with the crystal layer 8 doped with a small amount of Mg (0.2 at % or less), a clad layer 9 doped with a large amount of Mg (0.3 at % or more) is grown. Thereby, a clad layer 9 suitably controlled in carrier concentration and layer thickness is deposited on the substrate 1, and a flat active layer 4 is laminated thereon, resulting in the formation of a multilayer crystal structure for laser oscillation. Since the groove is filled with a crystal layer, the growing speed does not decrease, and the coefficient of As diffusion in the growing solution is kept constant; accordingly, the groove is filled rapidly. As a result, the growing surface of the crystal layer is almost flattened in a relatively short time. Next, a perfect hetero junction which prevents the leakage of carriers from the active layer can be obtained by depositing a flat active layer on the clad layer 9 having a sufficient carrier concentration.
