Title: Phase comparator
Inventor: NAKAGAWA JUNICHI
IPC: H03L7/089
Filed: 1986-11-07
Abstract: PURPOSE:To improve the linearity of input/output characteristic by extending the propagation delay time of a logic gate, which outputs a signal to simultaneously reset two output signals, out of plural logic circuits constituting a phase comparator. CONSTITUTION:The channel width of a transistor TR constituting a NAND gate 15 out of nine NAND gates 1-8 and 15 is narrowed to extend the propagation delay time. With respect to another method to extend the propagation time of a logic circuit, the magnitude of a charging current is reduced in case of an I<2>L logic circuit, and the operating current is reduced in case of an FCL or TTL logic circuit. Whichever logic circuit is used, the linearity of input/ output characteristic of the phase comparator is improved without extending the circuit scale.

Title: Wireless communication system and directivity control data generator
Inventor: MATSUGAYA KAZUOKI
IPC: H04W24/04
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a wireless communication system that controls directivity of an antenna of a mobile station with excellent follow-up capability and high accuracy. SOLUTION: A database of directivity control data to control directivity of the mobile station is retrieved based on the current position of the mobile station (S210), and in the case that corresponding directivity control data are not registered and the directivity control data cannot be acquired (S220-N), the arrival direction of a radio wave from a base station is detected (S270). Then, radio wave propagation characteristic data are obtained by cross- referencing the detection result and the current position above and the directivity control data corresponding to the current position are added to the database based on the result (S280).  Since it is not required to calculate a radio wave propagation path by using the directivity control data, the directivity of an antenna can quickly be controlled with excellent followingness and since the database is updated by detecting the arrival direction of the radio wave, the directivity can be controlled with high accuracy while reflecting a surrounding state.

Title: Rotary actuator
Inventor: KONDO JIRO
IPC: H02K33/16
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide with a simple construction a rotary actuator which can reduce a detent torque applied to a rotor, without increasing a structural size. SOLUTION: A stator 45 consists of an outer stator 46 and an inner stator 47. Slits 48 and 49 are formed in the inner stator 47, so as to have their extensions overlap each other in a diametrical direction and are extended, so as to facilitate the passages of fluxes in the excitation direction of the outer stator 46. Therefore, a detent torque developed by the outer stator 46 and a detent torque developed by the inner stator 47 are opposite in phases to each other and cancel each other. As a result, a detent torque applied to a rotor 41 can be reduced without increasing the structural size. Further, by properly selecting the lengths or widths of the slits 48 and 49, the value of the detent torque developed by the inner stator 47 can be adjusted.

Filed: 1984-12-14
Abstract: PURPOSE:To maintain a satisfactory operating performance of an engine, by determining a reference rotational speed which decreases as the selected gear ratio of a speed change unit decreases, in accordance with the selected shift position, and by controlling the air-fuel ratio to be lean when an actual rotational speed exceeds the reference rotational speed and upon low load operation of the engine. CONSTITUTION:Upon operation of an engine, in a control circuit 22 which receives signals from sensors 20, 34, 36, 40, 42, 48 for detecting various operating conditions, a reference rotational speed NR is searched in accordance with the present gear shift position. This reference rotational speed NR is determined such that the smaller the gear ratio, the smaller the speed NR becomes. The determined reference rotational speed NR is compared with the present actual engine rotational speed Ne. Further, if Ne>NR, when a lean mixture condition is establied, that is, the engine is in a low load but high rotational speed range in which the temperature of cooling water is below a predetermined value (about 75 deg.C), and the opening degree of a throttle valve is less than, for example, 30 deg.. A lean mixture compensating coefficient is set in accordance with the pressure of an intake pipe. Further, a reference injection time which is obtained by calculating the rotational speed of the engine and the pressure of the intake-air pipe, is compensated.

Filed: 1994-10-04
Abstract: PURPOSE: To improve the usability by detecting the output signal of a 1st reset means and the output signal of a 2nd reset means, sending and receiving data to and from a terminal connected to a line, and outputting a specific reset signal according to those output signals. CONSTITUTION: A CPU 1 once detecting a signal showing that the information processor is reset by its internal reset circuit 5 reads data out of a specific address of a ROM 3 to perform reset processing. The reset circuit 5 outputs a reset signal to the ISA interface 18 of a line switching part simultaneously with the output of a reset signal to the CPU 1. A reset circuit 17 monitors the state of the power source of the line switching part, and outputs the reset signal to the ISA interface 18 when the voltage drops below a specific threshold value. The line switching part when inputting data indicating the masking of the reset signal from the information processor outputs a signal for masking the reset signal to the ISA interface 18.
