Title: Image forming device
Inventor: SHIRATORI TATSUYA
IPC: B65H3/06
Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To enhance the carrying force by providing a driven roller abutting against a feeder roller and drivenly rotating thereby in the downstream side of a carrying direction of a separation means. SOLUTION: A separation pad 15 can energize only an optimal pressure to a feeder roller 14, however, a driven roller 18 can set a sufficient pressure to secure a carrier force. When a transfer material receiving the carrier force by the feeder roller 14 and the driven roller 18 is carried to a resist roller 16, a resist front sensor 19 detects the tip of the transfer material with the resist roller 16 stopped and drives a feeder roller 14 after a prescribed time. This constitution forms a prescribed quantity of loop between the resist roller 16 and the driven roller 18 with the edge of the transfer material thrust into a nipple of the resist roller 16 and corrects inclined moving.  In this case, the sufficient carrier force is applied to the feeder roller 14 and the driven roller 18 so that there is no possibility of causing inferior inclined moving and inferior vertical resist caused by shortage of the loop quantity.

Abstract: PURPOSE: To surely destroy and drop only a thrust deflecting body part in the case where thrust deflection becomes unnecessary during flight by providing a nozzle which has a jetting port turned toward the thrust deflecting body and is connected to a refrigerant tank for cooling action in a thrust direction control device having the thrust deflecting body. CONSTITUTION: A vane type of thrust deflecting body 1 is attached within a jet nozzle 4 in the tail part of a flying so that it may rotate round a shaft 21 at one end. During the flight of the flying body, a deflection driving device 2 functions to tilt the thrust deflecting body 1 round the shaft 21 for deflecting the direction of the thrust. In a case where such thrust deflection becomes unnecessary, a control valve 6 is opened to spray a cooling refrigerant pressure- accumulated in a tank 5 from a nozzle 7 toward the thrust deflecting body 1. Thus the thrust deflecting body 1 which is exposed to high temperature jet gas to attain high temperature above 1000 deg.C is destroyed by thermal shocking action caused by quenching, and separated and scattered by the jet gas.

Abstract: PURPOSE:To prevent the yield of drift or deformation in a voltage waveform to be measured, in an electron beam apparatus, by providing a means, which corrects an analyzed amount of voltage change, a slice level and a feedback coefficient that are obtained in energy analysis each time by using the statistical change in analyzed amount of voltage change. CONSTITUTION:The difference between a threshold level 14 and a secondary electron signal 11 detected at every irradiation phase is multiplied by a feedback coefficient 15. Then an amount of change 12 of an analyzed voltage of energy next time is operated in each irradiation phase. Then the analyzed amount of the voltage change 12 obtained in every irradiation phase is inputted into a correcting means 2 for the analyzed amount of the voltage change. The stastical change corresponding to each irradiation phase of the analyzed amount 12 of the voltage change is approximated using a straight line. The straight line component is subtracted from the analyzed amount of the voltage change. Thus each amount of change 12 is corrected, and a corrected value 13 of the analyzed amount of the voltage change is outputted. When the detected secondary electron signal 11 approaches the threshold level 14, the energy analysis is repeated, and the correct voltage waveform is measured.

Title: Gas-blast load-break switch
Inventor: KANEMAN NAOHIRO
IPC: H01H9/54
Filed: 1990-11-13
Abstract: PURPOSE:To prevent wear of an arc contact by connecting a semiconductor switch to a part between a fixed main contact and a fixed arc contact, and controlling the semiconductor switch so that arcs are not generated at the time of ON operation or OFF operation. CONSTITUTION:A part between a fixed arc contact 3 and a fixed main contact 1 is insulated while the contact 1 is connected to the contact 3 through a semiconductor switch 8 which is controlled by a switch controller 9. At the time of ON operation the semiconductor switch 8 is controlled to have continuity after a movable arc contact 7 is brought into contact with the contact 3, while at the time of OFF operation the switch 3 is controlled to be in the closed conditions while the contact 7 is brought into contact with the arc contact 3 after the contact 5 is apart from the contact 1. Consequently, no arcs are generated between both contacts 3, 7 at the time of ON operation and OFF operation, which prevents wear of the arc contact to thereby prolong the service life of a switch.

IPC: G05G1/08
Filed: 1999-10-26
Abstract: PROBLEM TO BE SOLVED: To provide a rotary knob with means for facilitating to attach and detach it to the rotary knob switch. SOLUTION: A rotary knob 50 has a support plate 60 rotatably engaging an attachment hole 38 not so as to be separated from an operational panel 34. The diameter of the knob hole 54 is made slightly greater than the conventional one, so that the switch shaft 30 is loosely inserted in the rotary knob 50, thus facilitating to attach and detach the rotary knob 50 to and from the switch shaft 30. Hence, the PWB 32 may be drawn in the inside 34A without the rotary knob 50 inadvertently being detached from the outside 34A of the operational panel 34. After replacing a component, the PWB 32 may be mounted in the inside 34A of the operational panel 34 while inserting the switch shaft 30 in the knob hole 54 of the rotary knob 50.
