Title: Differential reduction gear
Inventor: KAWAKAMI TAKASHI
IPC: F16H1/36
Filed: 1979-09-04
Abstract: PURPOSE: To achieve a high speed-reduction ratio with ease by obtaining a differential gear mechanism and a coupling gear mechanism, both composing the subject gear, through such a simple constitution as a small number of ordinary spur gears and the like are combined with each other.  
     CONSTITUTION: When the 2nd input axis 12 is rotated by operating an electromotor 19, a sun gear 6 supported by the axis 12 is rotated at the same rotational speed with that of the output axis 19a of the electromotor 19. At the same time, the 1st input axis 11 coupled to the above axis 12 through the intermediary of a coupling gear mechanism 3 rotates at a fixed rotational-speed ratio to the axis 12, and a planet gear 7 supported by the axis 11, rotating on its axis, rotates round the sun gear 6. As a result, an interior-teeth wheel 5 and an output axis 13 rotate at a low speed corresponding to the difference of the rotational speed between both input axes 11 and 12. In this way, said device enables attainment of a very large speed- reduction ratio through the appropriate selection of the gear ratio of the coupling gear mechanism 3.

Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor integrated circuit which can remove relatively large noise, even if it is inputted and is tolerant of noise and high in reliability by making different the switching speeds or switching periods of 1st and 2nd MOS transistors which are connected in series. SOLUTION: PMOS transistors P1 and P2 and NMOS transistors N1 and N2 are adjusted in channel resistance and a gate threshold voltage to generate differences in switching speed between the MOS transistors themselves. If noise is inputted, the NMO transistor N1 turns off first, and then the NMOS transistor N2 turns off a certain time layer. Further, the PMOS transistor P1 turns on first, and then the PMOS transistor P2 turns on a certain time later. At this time, the PMOS transistors P1 and P2 are never turned on at the same time. Consequently, an output terminal is not connected to a source voltage Vcc, and the noise is not transmitted to the output terminal.
