Patent JP-S6487939-A (JP)
Title: Power transmission
Inventor: FUKUMOTO RYOICHI
IPC: F16H21/16
Filed: 1987-09-30
Abstract: PURPOSE:To make it possible to operate a captioned transmission manually and electrically by use of an operation lever by making the lead angle of a worm gear larger than the friction angle. CONSTITUTION:Generally, when the lead angle of a worm gear becomes larger than the friction angle, the torque transmission from a worm wheel to the worm gear becomes possible. Therefore, the lead angle of a worm gear 27 is made to be larger than the friction angle to make it possible to rotate the worm gear 27 from a worm wheel 18. The selection of such lead angle of the worm gear 27 allows the worm wheel 18 to be returned to the original position by means of a spring 24 immediately after the operation by a driver even if the worm wheel 18 is rotated by door lock operation by means of an electric motor 26 by the driver, for example and the driver to perform the next manual operation. This eliminates a clutch between the electric motor 26 and worm gear 27 and a shift lever 17 for allowing a device itself to be simplified and miniaturized.

Title: Digital servo controller
Inventor: KASHIHARA TOMIO
IPC: G05D3/12
Filed: 1983-12-27
Abstract: PURPOSE:To perform positioning with high resolution and at the same time to improve the S/N of a low-speed signal together with high stability with a digital servo controller, by calculating the information which decides the control speed from the number of genuine shift pulses, the speed feedback element and a prescribed shift target position of an object. CONSTITUTION:A CPU21 of an arithmetic control circuit 20 supplies the shift information CG and DG from counters 13 and 14 of a shift information detecting circuit 10 to obtain a shift degree VFV for a period during which a clock pulse is supplied. Then the degree VFV is added to the position information on the preceding clock input mode to obtain the present position information PFD. This information is compared with the reference position information PIN of an ROM22. Then the drive control information MG of a motor 1 is produced to set the difference obtained from the comparison at zero. The information MG consists of the information to decide the turning direction and the information PW to decide the speed. The information PW is obtained by calculating a speed feedback element VFD from the change of the number of genuine shift pulses and then calculating PW=K0(PIN-PFD-K1VFD), where K0 and K1 show a time conversion coefficient and a speed feedback coefficient respectively.

Title: Communication system
Inventor: OKAJIMA YOSHINORI
IPC: H04L12/40
Filed: 1994-10-12
Abstract: PURPOSE: To shorten a transmission cycle by preventing the transmission timing of respective stations from being dispersed by calculating waiting time from reception time to the next transmission timing based on the address values of other stations and presetting this calculated value as the initial value of a timer. CONSTITUTION: Each time the transmitted data of the other station are received, at each station, the waiting time from this reception time to the next transmission timing is calculated by a timer setting circuit 106 and a transmission track timer 105 is preset. Since each station repeats the operation to successively transmit data corresponding to the lapse of waiting time counted by each timer 105, 1-to-N communication between a host station and slave stations is performed. With this system, since processing from the reception of data to the preset of the timer 105 at each station is performed by a hardware circuit (a circuit 106), the time required for that processing is shortened and dispersion is almost eliminated.

Abstract: PURPOSE:To change the delay time only with wiring change and to select two kinds of delay times by constituting the title circuit with plural inverters connected in series, the 1st input signal terminal, the 1st AND circuit, an inverter, the 2nd AND circuit and an OR circuit. CONSTITUTION:In bringing the level of the 2nd signal input terminal 5 to a high level logical 1, a path passing through 4 stages of inverters 21-24 is selected to an input signal IN1 to maximize the delay time. In bringing the level of the 2nd input terminal 5 to a low level, the signal IN1 passes through two stages of inverters 21, 22, a path passing through the 2nd AND circuit 27 from a connecting point 29 and the delay time is halved to that with logical '1' level. In general, since the number of inverters connected in series is a number required for the maximum delay time and a point giving a required delay time wh en the level of the 2nd signal diode is brought into logical '0' is selected as a connecting point to which the input terminal of the 2nd AND circuit 27 is connected, two kinds of delay times are selected by having only to bring the level of the 2nd signal input terminal 5 to logical '1' or logical '0'.

Abstract: PURPOSE:To have just one radio wave that arrives at a mobile station and therefore to eliminate the crosstalk areas, by providing a function to the mobile station to select a base station and an advance base station and stopping the working of the base station which is not discriminated nor selected by the base station. CONSTITUTION:A mobile station 7 actuates a signal generator 26 to select a base station 1 or an advance base station. While the station 1 decides whether own station 1 of the station 4 is selected based on the selection signal given from the station 7. Then a control part 23 in the station 1 stops the actuation of a radio unit 20 of the station 1 or a radio unit 29 of the station 4 which is not selected based on the result of discrimination. Therefore just one radio wave reach the station 7. Thus the crosstalk areas can be eliminated.
