Title: Shift control device for automatic transmission for vehicle
Inventor: IWATSUKI KUNIHIRO
IPC: F16H59/08
Filed: 1990-03-22
Abstract: PURPOSE:To prevent occurrence of a busy shift as engine brake is ensured by using a shift pattern having a high speed stage at which engine brake is effective when an overdrive switch is turned OFF. CONSTITUTION:When an overdrive switch is turned OFF, from the beginning, it is prevented from occurring that a speed stage at which engine brake is ineffective though the speed stage is used during relatively high speed running regardless of the condition of a throttle opening, i.e. a condition of whether engine brake is needed or not is selected. As a result, for example, a case in which, even when the overdrive switch is turned OFF, engine brake is ineffective during high speed running is prevented from occurring, and beside a trouble in which frequency shift occurs due to operation of an accelerator can be prevented from occurring. Furthermore, in this invention, during overdrive running, engine brake is effective without fail.

Title: Automatic focusing system
Inventor: NEMOTO RYOJI
IPC: G02B7/28
Filed: 1987-03-27
Abstract: PURPOSE:To remove the influence of variation in the thickness of a member and to improve defocusing detection accuracy by detecting defocusing optically in the form of the contrast ratio of two light and shade pattern projected on the surface of the member. CONSTITUTION:A wafer 12 on an XYZ base 10 is irradiated with an S-polarized laser beam 14 and vertical scattered light is received by a photodetection part 20 to extract a P and an S polarized light component and also move and scan the base 10. Parallel white light is projected on pattern plates 22 and 24, a lens 30 is adjusted to project a pattern of light and shade stripes on the wafer surface, and the intermediate point between both plates at the time of focusing is image-formed on the wafer. Shade parts 22a and 24a of the pattern are arranged alternately. A control circuit 34 controls and drives the base 10 with a signal from the output of a two-dimensional CCD 32 to cancel deviation in focusing. The visual field 32a of the CCD 32 is handled while image pickup areas A and B of the pattern stripes 24a and 22a are divided alternately. The intermediate point between two successive light and shade patterns is image- formed on the wafer surface, so any pattern becomes light images and the mean contrast is nearly 1. Consequently, the focusing is performed stably with high accuracy.

Title: Microwave voltage controlling oscillator using dielectric resonator
Inventor: WATANABE SATORU
IPC: H03B5/18
Filed: 1981-05-18
Abstract: PURPOSE:To improve the stability of the titled oscillator and to take out electric power efficiently by connecting a transistor for oscillation to one of two parallel microstrip lines connected between a dielectric resonator and a diode for modulation to the other. CONSTITUTION:When the impedance of a transistor 4 connected to a microstrip line 2 against a terminal resistor 6 connected to the other end of the line 2 is made negative resistance, oscillation is started by the resonance frequency of a dielectric resonator 8 connected to the microstrip line 2. The junction capacitance of a diode for modulation connected to a microstrip line 3 is changed by the control voltage applied to a bias terminal 12 for modulation. Consequently, the resonance frequency of the dielectric resonator 8 is changed through the microstrip line 3, modulating an oscillated signal. The modulated signal is outputted through a loop 10.

IPC: H03F3/19
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To provide the high frequency circuit having a low noise characteristic and a low distortion characteristic. SOLUTION: This circuit is made up of at least a 1st stage BJT amplifier and a final stage amplifier consisting of a MOSFET 12a. Thus, a high frequency signal received by an input terminal 1 is amplified by the BJT amplifier 11a and amplified by the MOSFET amplifier 12a and the amplified signal is outputted from an output terminal 2. The BJT amplifier 11a has a lower noise and a high gain but has a high level noise. On the other hand, the MOSFET amplifier 12a has a low distortion, a low gain and a high level noise. Thus, a low noise characteristic is obtained by the 1st stage BJT amplifier 11a that dominates the noise characteristic and a low distortion characteristic is obtained by the final stage MOSFET amplifier 12a that dominates the low distortion characteristic.

Abstract: PURPOSE:To surely bring a film into contact with a magnetic head by constituting a pad which presses a film surface to the magnetic head so that it can rock in a direction vertical to a film traveling direction. CONSTITUTION:When the film 2 should be stably brought into contact with the magnetic head 1 by pressing the pad 4 to the film 2, a gap is formed between a head gap and the film and becomes hindrance to the accurate write and readout of information in the case that the magnetic head 1 is inclined and attached because of the errors of parts and mounting error, etc. In such a case, by attaching the pad 4 to a pressing lever by a projection part 4a so that it can rock, the pad 4 is inclined by gamma and a film contact part 4b is along the magnetic head 1. Therefore, the film 2 is stably brought into contact with the head gap.
