Title: Totally-enclosed electric compressor
Inventor: SESHIMO KOUJI
IPC: F04B39/12
Filed: 1978-12-01
Abstract: PURPOSE: To prevent the release of return refrigerant gas into a totally-enclosed container for reducing a cylinder chamber in capacity by providing a porous material in the clearance between the expanded portion of the suction pipe of a suction silencer and a return refrigerant gas inflow pipe.  
     CONSTITUTION: A compressor mechanism 2 and a motor 3 are provided in a totally-enclosed container, and the internal pressure of the container 1 is reduced low. A porous material 27 is provided in the clearance A between the expanded portion 26 of the suction pipe 25 of a suction silencer 22 provided on the compressor mechanism 2 and an inflow pipe 24 in which return refrigerant gas flows. The large flow resistance of the material 27 prevents the release of return refrigerant gas into the space B of the container 1 so that the whole quantity of return refrigerant gas is introduced into a cylinder chamber 10 to reduce the heat required for heating refrigerant gas. Thereby, suction refrigerant gas is reduced in specific volume for reducing the chamber 10 in capacity.

Title: Runaway detection device
Inventor: DOI YOSHINORI
IPC: G06F11/30
Filed: 1994-06-29
Abstract: PURPOSE:To optionally set runaway state detection timing and prevent the load on a CPU from being increased by judging the match of an expected value of data outputted when a storage part is accessed and data outputted onto a data bus.

Filed: 1993-06-18
Abstract: PURPOSE:To prevent the reduction in the heating capacity during the warming-up control at the time of heating operation mode at a very low temperature, while avoiding the negative pressure operation of a compressor. CONSTITUTION:During the warming-up control at the time of heating operation mode for heating the inside of a vehicle room, by stopping the operation of an indoor evaporator 5 and heating the air passing through an indoor condenser 6, the rotating speed of an electric motor 45 of a compressor 32 is controlled so as to bring the blowing-out temperature at the outlet of the indoor condenser 6 close to a target blowing-out temperature. At that time, by increasing the rotating speed of the electric motor 45 of the compressor 32, even if the intake pressure of the compressor 32 decreases below 0MPa to cause the compressor to enter negative pressure operation, the negative pressure operation of the compressor 32 can be avoided by changing over to the dehumidifying heating operation mode in which even the indoor evaporator 5 can be operated as an evaporator.

Title: Photoelectric switch
Inventor: SHIMAJI NAOHIRO
IPC: H03K17/78
Filed: 1993-06-21
Abstract: PURPOSE:To increase the projection current of a compact and lightweight photoelectric switch and to extend a set distance up to a detected article. CONSTITUTION:A projecting circuit 2 and a light receiving circuit 4 are serially connected to a DC power supply circuit 1. A current Ia of constant voltage Vb is supplied from the circuit 1 to the circuit 2 to emit a projecting element 3, so that the projecting current Ic of the element 3 is increased and the intensity of light emission is increased. In order to stabilize the input voltage of the circuit 4, a constant voltage circuit 6 is connected to the circuit 4 in parallel. A current from the circuit 2 is allowed to dividedly flow into respective circuits 4, 6. Consequently the increment of the projection current and the extension of a set distance can be attained without increasing the power consumption of the circuit 1 capable of most easily generating heat while holding the compact and lightweight property of the photoelectric switch.

Filed: 1997-06-05
Abstract: PROBLEM TO BE SOLVED: To prevent an accident by detecting/judging the invasion of an object when the object invades into a prescribed monitor area and automatically generating alarm. SOLUTION: The monitor area 1 in a railroad crossing on a railroad 11 is divided into two boundary areas 6 and 6 in an entrance where breakers 2 descend and a center danger area 7 where a train passes through. Two cameras 3 and 3 can photograph the whole areas of the monitor area. A controller 4 detects a moving vector based on video data obtained by executing a processing required for a picture taken by both cameras, and judges the invasion of the object into the railroad crossing area. At the time of judging invasion, an alarm is generated from a speaker 5. The cameras and a timer control ON/OFF from a control circuit and service information of the train is supplied to the control circuit. A judgment circuit emits an urgent stop command to the train when the object is not saved from the danger area in a situation where the train does not approach the railroad crossing area.

Title: Image pickup device
Inventor: ASANO HIROSHI
IPC: G01S17/88
Filed: 1982-08-26
Abstract: PURPOSE:To pick up an image of a target stably even in case of variation in relative distance, by providing an image pickup device with a range gate pulse generating circuit as a function substituting a range finding device. CONSTITUTION:A laser beam 2 emitted from a laser light emitting device 1 strikes the target and then the range gate pulse generating circuit 20 operates at the time when its reflected light arrives at an image multiplier tube (I.I)6. A pulse has two kinds of generation timing and is generated in an odd-numbered field earlier than the reflected light arrival time. On the other hand, a gate is opened in an even-numbered field almost the moment the range gate is closed in the odd-numbered field. Therefore, when the reflected light arrives at two kinds of center time, the difference in the video signal value between both even and odd fields is zero. If the center deviates from the reflected light arrival time, outputs of a subtracting circuit 18 and an integration circuit 19 have an error and the range gate center is brought under follow-up control to coincide with the reflected light arrival.

Title: Amplitude detecting method of vibrator
Inventor: SEKINE TOSHIRO
IPC: G01H1/16
Filed: 1990-06-07
Abstract: PURPOSE:To make it possible to detect the value which is close to an actual amplitude even if a large noise is included by operating the amplitude based on the effective value of the output of an acceleration detecting element. CONSTITUTION:A detecting element for detecting vibrating acceleration, e.g. a vibration detector 40 made of lead zirconate, is applied on or attached to a part of a vibrator, e.g. an electromagnetic vibration feeder 60, so as to face the vibrating direction. Then, the output containing many noises in sine wave forms is obtained. At this time, the time root-mean square of the instantaneous values of the outputs of the detector 40 for detecting the vibrating acceleration, i.e. the effective value, is operated. The amplitude is operated base on the value. Even if the large noises is contained, the generating time of the noise is short, and the effect can be almost disregarded. Therefore, the detected amplitude obtained in this way is very close to the actual amplitude.
