Abstract: PURPOSE:To produce the title reduction-reoxidation type semiconductor porcelain having low porosity and with small variance in the breakdown voltage by press-forming raw powder or its compact, then hot-pressing the formed article to obtain a calcined body, reduction-calcining the body, and then reoxidizing the body at the time of producing a reduction-reoxidation type semiconductor porcelain. CONSTITUTION:When a reduction-reoxidation type semiconductor porcelain is produced, a binder is added to the raw powder, the powder is granulated, the granules are heated to volatilize the binder, and the granules are press- formed. The formed article is hydrostatically and isotropically pressed at 1,000kg/cm<2> pressure, and then further compression-molded. The compact is hot-pressed to obtain a calcined body, the body is calcined in the air at 300kg/cm<2> pressure and at 1,300 deg.C, the calcined body is reduced and calcined in gaseous H2 at 800-900 deg.C, and the body is reoxidized in the air at 900-1,000 deg.C. As a result, a reduction-reoxidation type semiconductor porcelain having less pores and with small variance in the breakdown voltage can be obtained.

Title: Control power source circuit for inverter
Inventor: KAI TORU
IPC: H02M7/48
Filed: 1994-06-22
Abstract: PURPOSE:To reduce loss in a switching element by disconnecting a starter power source circuit when the voltage from a detecting winding rectified after a control circuit starts operating becomes higher than the voltage of the starter power source. CONSTITUTION:When a voltage VDC rises to exceed the voltage of a constant- voltage diode 55, a starter power source circuit starts operating and outputs a voltage Vcc. The voltage generated at a detecting winding 15 forms a voltage control loop in a control circuit 12, and stably controls the output voltages of the secondary windings of transformers 13, 14. The voltage generated in the winding 15 is converted to a DC voltage via a rectifier 16, and input to a priority circuit having diodes 51, 52. When the voltage VD exceeds the voltage Vcc, the diode 51 of the priority circuit is reversely biased, and the current from the voltage Vcc is interrupted. Accordingly, the circuit 12 continues operating at the voltage VD. Thus, the starter power source supplies the current only for a short time until the control circuit starts operating, and hence the loss is extremely reduced.

IPC: G03B27/62
Filed: 1984-07-09
Abstract: PURPOSE:To make it possible to feed out an original which is even curled at its leading end, by pressing the leading end of the original paper set on an original tray, against a feed belt with the use of a holding mechanism. CONSTITUTION:When the leading end of an original 11 is curled, a solenoid 31 attracts a plunger 32 to rotate a holding lever 35 counterclockwise overcoming the force of a spring 40, and therefore, the front end of the lever 35 holds the leading end section of the original 11 at the center thereof. Therefore, the center of the leading end section of the original 11 is absorbed onto a feed belt 5 by means of an air suction mechanism 4. Further, the solenoid 31 is deenergized before travel of the feed belt 5. Therefore, the holding lever 35 is rotated clockwise under the force of the spring 40 to make an overlapping feed preventing mechanism 6 effective to prevent overlapping feed. Further, the lowermost original copy is alone fed out from the original tray 3 in association with the travel of the feed belt.

Title: Electronic tuning unit
Inventor: HIROSE FUMINORI
IPC: H03J5/12
Filed: 1978-11-15
Abstract: PURPOSE: To make preset operation feeling light by connecting a tuning volume, which is paired together with a selector switch, to a tuning finger-screw through a clutch at a preset operation time.  
     CONSTITUTION: When selector switch 2c is depressed for preset, internal contact 3c is turned on to apply a prescribed voltage to an electronic tuner. At this time, clutch 10C in the back of tuning volume 4c which is so provided that this volume may be paired together with switch 2c is connected to rotary wheel 11c. Rotary wheel 11c is interlocked with tuning finger-screw 1 for preset through a timing belt. Consequently, since the tuning finger-screw and the tuning volume are connected to each other only when the selector switch is depressed, preset can be performed by turning the tuning finger-screw at this time, and the prescribed voltage of the tuning volume is applied to the electronic tuner. As a result, this unit has the same operation as a conventional car radio, etc., but can be made light-operation feeling and small-size.

Filed: 1980-10-08
Abstract: PURPOSE: To make the speed of turning during work proper, and to prevent an engine failure by connecting a travelling car body and the rice-transplanting machine by means of a lifting working mechanism and changing over a stepless variable speed mechanism of a drive system to the low speed side by lifting the rice-transplanting machine.  
     CONSTITUTION: When the depth of a paddy field varies during work and a soil preparation float 16 rises or falls, an oil pressure changeover valve 30 is automatically changed over, and the rice-transplanting machine 12 rises or falls. When a lever 31 is operated in the direction opposite to an arrow (a) in order to turn the travelling body 1, a wire 48 works a tension pulley 42 in the arrow (b) direction, and a belt 40 is stretched while the oil pressure changeover lever 30 is changed over. Accordingly, the stepless transmission 34 is operated in the deceleration direction and decelerated. Consequently, since the transmission is decelerated automatically when resistance at the time of turning increases, excessive force is not applied to a prime mover 6, and the engine failure can be prevented while an engine is turned at proper speed.
