Abstract: PURPOSE: To provide a sealing device whose opening is impossible unless a seal is destructed. CONSTITUTION: This device is composed of a female member (cage 1) and a male member (rotor) 2 molded by a plastic material, and when the knob 17 of the rotor 2 is held and the rotor 2 is inserted to the cage 1 and rotated counterclockwise, a male screw 19 is engaged with a female screw 11 and screwed to the position of the drawing. A wire required for sealing is hooked to a sealing object at the position and both ends are gathered and passed through an opening 10, a passage 18 and the opening 10. Then, when the rotor 2 is half-rotated for instance counterclockwise further, since a pawl 12 and a ratchet 6 are engaged and locked, the rotor 2 can not be rotated clockwise unless the device is destructed. After locking, the knob 17 can be torn off.

Filed: 1999-06-30
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of a tooth top from occurring by engaging one gear with the other rotating gear in the case where one of gear approaches the other one. SOLUTION: When a driving motor is rotated for a prescribed hours, a behavior moved to a transfer driving gear 16A side is generated by a transfer driven gear 19A1 by a behavior for holding a closing condition of a manual paper feed tray as a behavior applied to a paper feed tray 15A. The paper feed tray 15A is closed while a tooth top of the transfer driving gear 16A and a tooth top of the transfer driven gear 19A1 are opposed to each other. When the transfer driving gear 16A is rotated after the paper feed tray 15A is closed, in the case where the tooth top of the transfer driving gear 16A and the tooth top of the transfer driven gear 19A1 are opposed to each other, the transfer driven gear 19A1 is engaged with the transfer driving gear 16A by the behavior.  The same phenomenon is generated between the resist gear 21B and a resist driven gear 21A1, and both gear 21B and 21A1 are engaged with each other.

Title: Output buffer circuit
Inventor: SHIRAISHI TAKESHI
IPC: H03K17/687
Filed: 1991-07-25
Abstract: PURPOSE:To prevent malfunction due to power supply noise and ground noise caused in the operation of the output buffer circuit of an LSI by interrupting tentatively a PMOS or an NMOS transistor(TR) only for a potential drop or a potential rise. CONSTITUTION:A power supply noise detection circuit 7 and a ground noise detection circuit 8 respectively control the conduction state of PMOS and NMOS transistors(TRs) P2, N2 of an output buffer 5. When a potential is dropped at an output power supply 1a, the output of an inverter 11 of the circuit 7 goes from L to H and the potential of a NOR circuit 12 goes to an L. Thus, the output of an inverter 13, that is, a power supply noise control signal CV goes from L to H and only the PMOS TR P2 is brought into an interruption state from the conduction state. Thus, a charging current is tentatively decreased and a potential drop at the terminal 1a is relaxed. The ground wiring is constituted similarly and only the NMOS TR N2 is controlled by a control signal CG to be brought into the interruption state from the conduction state and the potential rise at a ground terminal 2a is relaxed.

Abstract: PROBLEM TO BE SOLVED: To make possible a three-phase 120-degree communication of a brushless motor, using a single positional sensing element, by performing such timing corrections as to make time points of a first timing signal whereat its logical level is inverted coincide with the zero-crossing points of a frequency signal. SOLUTION: In this drive controller 10, a signal generating means 20 generates first to third timing signals j, d, d' based on Hall signals u+, u- obtained from a single Hall element Hu, and performs the maskings of the unnecessary portions of the signal synthesized out of a frequency signal FG and the Hall signals u+, u- to be the bases for forming the second and third timing signals d, d'. Also, in this drive controller 10, when discrepancies between the Hall signals u+, u- and the frequency signal FG are generated, there are performed such timing corrections as to make the inversion timings of the first timing signal j whose logical level is inverted at the zero-crossing points (O degree, 180 degrees) of the Hall signals u+, u- coincide with the zero-crossing points of the frequency signal FG.  Thereby, using a single positional sensing element, the three-phase 120-degree switching communication of a brushless motor is made possible.
