IPC: H03L1/02
Filed: 1986-02-28
Abstract: PURPOSE:To compensate any temperature fluctuation in a short time by storing a temperature compensation value in response to the fluctuated temperature in advance through digitizing and reading a compensation value while taking a digital value of the fluctuated temperature as an address. CONSTITUTION:A temperature is detected (101), an analog signal corresponding to the detected temperature is outputted and the signal is converted (102) into a digital signal. The value to be compensated corresponding to each fluctuation temperature is stored (103) in advance as a digital value and the output of an A/D converter 102 is used as an address and the value to be compensated is outputted digitally. In the temperature compensation circuit 201, since the detected fluctuation temperature and the compensation digital value of a ROM 103 correspond to each other by one to one, the value subject to temperature compensation is outputted easily in a short time and even when the characteristic to be compensated is nonlinear, the characteristic is traced.

Abstract: PURPOSE: To obtain a preferable combustion state of an auxiliary engine in its initial running by a method wherein an apparatus which reduces the throttling of an air intake device by closing an air intake shutter at the starting of an auxiliary engine is provided.  
     CONSTITUTION: In an air intake passage 2 communicating with a combustion chamber of engine 1, is provided with an air intake shutter 4 of a butterfly valve in the manner freely openable. When an auxiliary engine is started for driving to charge load on the engine 1, a cooler switch 33 or a switch 39 checking the running of the auxiliary engine is closed.

Filed: 1991-03-11
Abstract: PURPOSE:To provide a highly reliable power supply apparatus by which frequent repetition of making/breaking of the voltage of a backup battery can be avioded and harmful influence upon electric equipment can be avioded. CONSTITUTION:If the voltage Ve of a battery 6 is higher than a reference voltage Vref when a commercial AC power supply 1 is interrupted, the voltage Ve of the battery 6 is cost into output terminals 3a and 3b. If the service interruption is continued and the voltage Ve of the battery 6 becomes lower than the reference voltage Vref, the voltage Ve is disconnected from the terminals 3a and 3b. At that time, the level of the reference voltage Vref is changed to rise and the voltage Ve of the battery 6 does not exceed the reference voltage Vref as far as it is not recovered to a sufficiently high level. The disconnected state of the voltage Ve of the battery 6, therefore, is continued.

Title: Multibeam antenna
Inventor: IWATA RYUICHI
IPC: H01Q19/18
Filed: 1988-02-27
Abstract: PURPOSE:To radiate waves in different directions simultaneously without lowering the phase efficiency of an aparture plane by constituting a main reflection mirror by joining two parabolic planes, and interposing a sub reflection mirror and a correction reflection mirror between three primary radiators. CONSTITUTION:The waves from first and second primary radiators 21 and 22 arranged at mirror image points F'a and F'b project the central part 51 of the sub reflection mirror 5 and curved surface parts 52 and 53, respectively, and reflected waves are radiated in parallel with the central axis of respective reflection mirror as if they are emitted from focal points Fa and Fb to partial reflection mirrors 31 and 32. Also, since the shape of the planes of the waves projected on the curved surface parts 53 and 52 are set so as to correct or reduce an error when their reflecting waves are radiated via the partial reflection mirrors 32 and 31, respectively, they are radiated in the same directions, respectively without lowering the phase efficiency of the aperture plane. The wave from a third primary radiator 23 is reflected on the main reflection mirror via the correction reflection mirror 6 and the sub reflection mirror 5, and is radiated in a third direction different from first and second central axes after its phase error is corrected or reduced.

Title: Pneumatic tire
Inventor: TERATANI HIROYUKI
IPC: C08L21/00
Filed: 1996-02-08
Abstract: PROBLEM TO BE SOLVED: To obtain a pneumatic tire improved in on-ice performance by using an expanded rubber contg. specific water-sol. fibers as the tread rubber. SOLUTION: This pneumatic tire uses, as the tread rubber, an expanded rubber contg. fibers sol. in water at 0 deg.C or higher. When a tire is run on ice, the pressure applied to the tire by the ground forms a water film between the tire and ice. In this pneumatic tire, water of the water film dissolves the water-sol. fibers exposed to the surface of the tread, thus forming numerous dents on the surface in contact with the ground. Such dents act to connect between cells of the expanded rubber and forms drain channels in the circumferential direction of the tire, enhancing the drainage capacity in the tire surface in contact with the ground. The improvement in capability for draining to the rear side in the direction of tire rotation leads esp. to the improvement in braking performance on ice.  Thus, this pneumatic tire exhibits much higher on-ice performance than a conventional expanded tire.

Abstract: PURPOSE:To reduce the shock when a direct connecting clutch is engaged, by using a variable capacity type fluid-type torque converter in which the capacity coefficient is variable, and increasing the capacity coefficient when the direct connecting clutch is engaged. CONSTITUTION:When a direct connecting clutch 28 is engaged under the condition that a fluid-type torque converter 10 is operating in the torque converter operational area, an electronic control device 70 releases a brake 24 which fixes a stator 16 selectively through a one-way clutch 18 by a brake oil pressure control valve 40, and makes the liquid-type torque converter 10 operate as a liquid coupling.
