Inventor: TAWARA YOSHITAKA
IPC: B60W10/10
Filed: 1988-07-29
Abstract: PURPOSE:To prevent the occurrence of a slip during gear shifting on a low mu road, e.g. a snow road, by a method wherein when a low mu road surface is discriminated by a road surface state discriminating means, an engine output during gear shifting is more widely reduced than a case in which a rod surface mu is high. CONSTITUTION:An electronic control device 3 inputs signals from a throttle opening sensor 31, a car speed sensor 32, and a crank angle sensor 34, and performs speed change of an automatic speed change gear 2 based on setting of a speed change step responding to a running state. During gear shifting, an ignition control signal is outputted to an ignition plug 36 so that an engine 1 output is slightly reduced by means of an engine output reducing means 38. Meanwhile, when it is discriminated by a road surface state discriminating means 37 by means of a mode signal from a mode select switch 33 that a road surface mu is low, an ignition control signal is outputted to the ignition plug 36 so that by means of a discriminating signal therefrom, the engine output reducing means 38 reduces an engine output more widely than a case in which a road surface mu is high. this constitution enables prevention of the occurrence of a slip during gear shifting on a low road, e.g. a snow road.

Title: Optical variable attenuator
Inventor: KONDOU SUMIO
IPC: G02B6/26
Filed: 1983-10-13
Abstract: PURPOSE:To detect an attenuation quantity accurately and easily and to improve the work efficiency of a test or the like by providing an optical variable attenuator with another half mirror, rod lens, and receptacle. CONSTITUTION:A half mirror 10 is placed between a filter disc 3 and a rod lens 2b and reflects a part of the light transmitted through the filter disc 3, and the reflected light is condensed to a fiber 5c inserted and fixed to a receptacle 1c by a rod lens 2c. By this constitution, a part of an optical beam 6 after attenuation is always taken out to the optical fiber 5c in a certain proportion. Consequently, the quantity of light which is taken out to the optical fiber 5c when the attenuation quantity due to the filter disc 3 is zero is defined as a reference value, and the attenuation quantity from this reference value is detected to detect the attenuation quantity of the filter disc 3. That is, the attenuation quantity of this optical variable attenuator is always detected accurately if the optical output value of the optical fiber 5c is measured, and therefore, it is unnecessary that an optical fiber 5b is removed from a sample material and is measured, and thus, the work efficiency is improved.

Title: Bias circuit
Inventor: TAGA NAOKI
IPC: H03F1/30
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent reduction of saturated output power by feeding back a voltage applied to a gate of a power amplifier FET to one input terminal of an operational amplifier and applying a prescribed divided voltage to the other input terminal so as to maintain a gate bias voltage. SOLUTION: A gate bias voltage Vg is fed to a gate of a GaAs FET 1 from a bias circuit 2 and power of an RF input signal S1 fed to the gate is amplified and an output signal S2 is outputted from the drain. A bias voltage Vgg divided by resistors 21, 22 is fed to a noninverting input terminal of an operational amplifier 23 of the bias circuit 2 and a gate bias voltage Vg fed to a gate of the GaAs FET 1 is fed back to an inverting input terminal of the operational amplifier 23. Thus, the operational amplifier 23 acts like a voltage follower so that the gate bias voltage Vg is equal to a voltage at the noninverting input terminal of the operational amplifier 23. Thus, even when the power amplifier GaAs FET is in operation near the saturation area, the gate bias voltage is kept constant.

Title: Fluorescent plate type monitor for charge particle device
Inventor: IIDA TOSHIAKI
IPC: G01T1/29
Filed: 1989-07-26
Abstract: PURPOSE:To allow the observation of the orbit position of the incident particles of the 2nd and subsequent circumferential rotation by providing the monitor which has the narrow width in a position detecting direction and is movable in the position detecting direction. CONSTITUTION:The orbit position of the charge particle oscillates around the plane orbit at every circumferential rotation when the progressing direction 4 of the incident charge particle on a circumferential rotation type particle device from an inflector 8 deviates from the plane orbit 9 determined by the disposition of a deflecting electromagnet, a quadrupole electromagnet, etc. The progressing direction of the charge particle in the position where the fluorescent monitor is installed, therefore, varies at every one circumferential rotation in general. Such fluorescent plate type monitor 1 is narrower in width than the conventional type and is movable and, therefore, the orbit position of the charge particle of an arbitrary circumferential rotation is observed.

Title: Recorder
Inventor: USUI TAKUMI
IPC: G11B5/53
Filed: 1998-07-07
Abstract: PROBLEM TO BE SOLVED: To compress recording signals so as to be recorded during the period other than the overlap period between recording and reproduction. SOLUTION: In a rotary magnetic head device in which input signals are recorded by first and second rotary heads Wa, Wb at least arranged adjacent and also the recorded input signals are reproduced by third and fourth rotary heads Ra, Rb arranged at positions facing these rotary heads roughly at 180 deg., the input signals are recorded by compressing an amount equivalent to an area, where a recording timing of the first and second rotary heads and a reproduction timing of the third and fourth rotary heads are overlapped with each other. More specifically, the input signals can be compressed by setting recording frequencies of the input signals higher by an amount corresponding to ΔL.  Since in this manner the overlap period can be excluded from the recording timing of the signals, the S/N ratios of the reproduced signal will not be degraded due to the leakages of recording currents.

IPC: H04Q7/28
Filed: 1993-08-03
Abstract: PURPOSE:To shorten communication instantaneous interruption time between terminals by holding a communication channel on a ground side when the quality of the channel of a mobile station and a base station is degraded and the mobile station selects the other base station. CONSTITUTION:In order to set the communication channel 4 between the base station B and the base station C beforehand, the channel is set between the base station B and a ground network D and then, the channel is set between the base station C and the ground network D. Then, when the channel quality of the communication channel 1 between the mobile station A and the base station B is degraded accompanying movement, the mobile station A selects the base station C. Then, the station A performs the channel releasing procedure of the communication channel 1 with the station B. After the procedure is completed, the communication channel between the terminal (o) and the terminal (p) is tentatively released. Then, when the communication channel 2 is set between a transmitter-receiver (f) inside the station A and the transmitter-receiver (h) inside the station C, the communication channel is set through the ground network D. Thus, the communication instantaneous interruption time of the terminal (o) and the terminal (p) can be shortened.

Title: Pressure sensitive sensor
Inventor: KIYOMIYA SADAO
IPC: G01G3/00
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To provide a pressure sensitive sensor which can precisely measure a weight and a pressure without complicating a structure. SOLUTION: A first dielectric piece 9 and a second dielectric piece 10 placed between a first electrode layer 53 and a second electrode layer 54 so that their cross-sectional shapes are laterally symmetric to each other are alternately placed. Thus when load is applied vertically to the first electrode layer 53, the first dielectric piece 9 and the second dielectric piece 10 function to prevent the first electrode layer 53 and the second electrode layer 54 from laterally shifting. Thus a region where capacitance of a pressure sensitive sensor linearly varies is increased.
