Title: Clutch device for earth drill
Inventor: AJIRO SHUICHI
IPC: E21B11/00
Filed: 1994-11-28
Abstract: PURPOSE: To surely prevent inadvertent connection by providing a return blocking lever operated by a spring when a clutch is released and the release lever of the return blocking lever on a clutch provided between a kelly-bar and a reel table. CONSTITUTION: When clutch members 10, 14 are driven to the connection release position, a restraining lever 24 is protruded on the shift path of the clutch member 14, and the return of the clutch members 10, 14 to the connection position is blocked. The restraining lever 24 is automatically protruded by the force of a spring. When the return block of the restraining lever 24 is to be released, downward force is applied from the outside by the actuator of a hydraulic cylinder or by manually via a lock release rod and a wire. A return block mechanism can be easily released from the ground even when a clutch is located at a high place. Inadvertent connection is prevented while the clutch is disconnected, and workability can be improved.

Title: Developing device
Inventor: MATSUURA MASAHIKO
IPC: G03G15/09
Filed: 1988-11-17
Abstract: PURPOSE:To reduce the amount of developer regulated by a regulating plate in a developing part and to restrain deterioration caused by regulation by supplying developer scooped up by a developer scooping part to the developing part by means of limiting it to a fixed amount by a regulating means. CONSTITUTION:The developer is scooped up to a recessed part 34 based on the rotation of a bucket roll 27 and supplied to the outer peripheral part a lower developing sleeve 15 at a supplying region R. At this time, developer on a surface part is scraped off by the regulation plate 22 and limited to under fixed amount before the developer passes through a facing part with a holder 20. The developer entered into the supplying region R interrupts its entry into the facing part Q of an upper developing sleeve 14 and the lower developing sleeve 15 from the lowest part of the holder 20, and is carried toward a facing part with napping regulating plate 18 with the aid of the rotation of the developing sleeve 14. The developer is limited to a fixed amount hereupon and sent to a downstream side. Since the developer sent from a bucket 29 is regulated by the napping regulating plate 18 after it is limited to under fixed amount by the regulating plate 22, in such a manner, the amount of developer which receives stress is little. Consequently, the deterioration of developer can be restrained.

IPC: H02M1/12
Filed: 1995-10-04
Abstract: PROBLEM TO BE SOLVED: To spread the conducting angle of a rectifier in a primary rectifying circuit, to improve the power factor of a device and to reduce the generation of a higher harmonic by separating a part of a primary winding for a voltage transformer and connecting a part of the primary winding between the rectifier in the primary rectifying circuit and a smoothing capacitor through a rectifier at high speed. SOLUTION: A rectifier 5 has characteristics, in which the rectifier 5 can follow up to switching operation at high speed of a switching element 13. When the switching element 13 reaches an on state, reverse voltage is generated in a separated winding 7, and a capacitor 4 is charged through the rectifier 5. The voltage of an output terminal for a rectifying bridge in a primary rectifying circuit is kept at a value obtained by subtracting the charging voltage of the capacitor 4 from the approximately charging voltage of a smoothing capacitor 3 in the low output voltage of a current bridge in the primary rectifying circuit. When the output voltage of the rectifying bridge 2 reaches the voltage of the difference of the charging voltage of the smoothing capacitor 3 and the charging voltage of the capacitor 4, a current begins to flow through the circuit.  Accodingly, the conducting angle of the rectifying bridge 2 is made considerably wider than there is no separated winding 7.

Title: Video display device
Inventor: NISHIKAWA HIROSHI
IPC: H04N5/44
Filed: 1995-11-13
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption by selecting automatically an output of a video signal received from a TV broadcast respectively section in the case of a monaural signal or an output of a video signal received from a teletext broadcast reception section onto a display section in the case of stereo signal so as to attain easy to see teletext display. SOLUTION: A display changeover section 3 conducts switching based on the result of detection by a stereo/monochromatic detection section 5. That is, in the case of a monaural signal, a video signal received from a TV broadcast reception section 2 is outputted and in the case of a stereo signal, a video signal received from a teletext reception section 1 is outputted to a display section 4 through the switching. This is because a broadcast program is transmitted by monaural signals and a commercial broadcast program is transmitted by stereo signals mostly in the existing TV broadcast system. Through the operation, in the case of reception of a program, a teletext broadcast indication is automatically selected for the user for viewing the teletext program. Furthermore, in the case of reproduction of a music CD, the display section 4 requiring a high power consumption is not used.  Thus, the power consumption is reduced.
