Title: Head leading mechanism of floppy disk unit
Inventor: ISHII HIROSHI
IPC: G11B21/02
Filed: 1984-05-28
Abstract: PURPOSE:To improve lead precision with simple structure while eliminating deviation of a shaft center by transmitting rotations of a pulse motor to a lead screw through gear coupling. CONSTITUTION:A carriage 2 on which a magnetic head 1 is mounted is supported on a shaft 3 slidably and led through the lead screw 11, and a gear 18 fixed on the shaft 11 engages with a gear 20 fixed on the shaft 19 of the pulse motor 4. Then, rotations of the motor 4 are transmitted to the lead screw 11 through the gears 20 and 18 and converted into linear motion by a rotary-linear motion converting member 16. Therefore, deviation between both shaft centers is absorbed by the gear coupling to improve the lead precision. Further, the male screw 17 of the thrust bearing consisting of a female screw 16 and the male screw 17 fixed on a frame is turned properly to adjust a track position.

Title: Electric discharge machining power source
Inventor: OBARA HARUKI
IPC: B23H1/02
Filed: 1983-06-20
Abstract: PURPOSE:To keep off any damage to a transistor, by turning on the transistor with condenser charging voltage of more than a reference value, while constituting it so as to be turned off simultaneously with the discharge end detection, in case of an electro-discharge machining power source for an electric discharge machine using the discharge of a condenser. CONSTITUTION:Charging voltage of a condenser C0 is detected by a charging voltage detection circuit (unillustrated herein) and compared with reference voltage, and when the detected voltage exceeds the reference one, a signal is fed to a base q1 of a switching transistor Q1 which is therefore turned on, causing a transistor Q2 to be turned off. Accordingly, discharge of the condenser C0 takes place. With a discharge current detected by a discharge current detection circuit (unillustrated herein), when a discharge end is detected, the transistor Q1 is turned off. With this constitution, during the discharge, the switching transistor is in no case turned off, thus breakdown in the switching transistor due to surge voltage is preventable.

Filed: 1995-05-08
Abstract: PURPOSE: To provide a retransmission device which avoids trouble from being imposed on an opposite party by stopping retransmission after reception by a person is recognized and displaying a notice. CONSTITUTION: When a channel state discrimination means 2 detects it that a channel is set between a communication device 10 and a communication device 50 of a transmission destination, a voice signal detection means 22 detects the presence of a voice signal. When the voice signal is detected, a voiced time detection means 23 detects whether the consecutive time of the voice signal is longer or shorter than a prescribed time. When shorter, a notice means 30 is used to display it that the communication device 50 of the transmission destination cannot receive document graphic data, and when longer, the notice means 30 displays it that a communication device corresponding to transmission destination information is not in existence. Then the control section 40 interrupts the channel and stops 2nd setting of the channel.
