Inventor: TERACHI TAKASHI
IPC: G06V10/24
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To provide a part recognition method and a device, where all parts can be accurately recognized under a gentle lighting condition, and picture images can be processed at a high speed. SOLUTION: The image of a part provided with a prescribed electrode arrangement pattern is picked up, a small window is swept from a corner 33a to extract a seed electrode 32. When the seed electrode is detected, HoVo coordinates are formed with the seed electrode as an origin, and surrounding electrodes are observed. In this state, a small window is set at a position that is predicted based on an extracted electrode group, and electrodes are successively extracted. In succession, an extracted electrode pattern and the coordinates of the electrodes are obtained, and the extracted electrode pattern and a prescribed arrangement electrode pattern are superimposed, collated with each other, and positioned.  When disagreements in both the patterns are less, the image coordinates of the electrodes of a prescribed arrangement electrode pattern are determined based on the coordinates of the extracted electrodes. By this constitution electrodes can be quickly extracted, and the accurate coordinates of the electrodes can be obtained.

Filed: 1994-03-03
Abstract: PURPOSE:To further shorten a defrosting time by providing a bypass channel in which refrigerant flows from an outdoor heat exchanger to a compressor at the time of reverse cycle defrosting and a capacity regulating mechanism for regulating refrigerant capacity at the time of defrosting at an outlet of the compressor. CONSTITUTION:High temperature and high pressure gas refrigerant fed from a compressor is sent to an outdoor heat exchanger 3 to dissipate heat thereby to melt frost, condensed to become liquid refrigerant, which is sent to an indoor unit. It absorbs heat from a room by an indoor heat exchanger 6 to become gas refrigerant, which is returned to the compressor. In order to shorten a defrosting time as much as possible, a bypass switching valve 9 provided at a bypass channel of the exchanger 6 is opened to bypass the liquid refrigerant to the compressor thereby to increase a load of the compressor to thereby increase an electric input of the compressor, thereby enhancing a condensing capacity of the exchanger 3. Further, a capacity regulating valve 10 is disposed at a discharge tube of the compressor to reduce an opening of the valve at the time of defrosting. As a result, higher temperature and pressure gas refrigerant can be supplied to the exchanger 3, thereby shortening a defrosting time.

IPC: F24F13/28
Filed: 1995-02-22
Abstract: PURPOSE: To provide an air filter capable of surely collecting dust in the air and washing with water, and an air conditioner provided with the air filter. CONSTITUTION: The air filter is constituted so as to have a fiber member 23 formed by coating the outer surface of a resin fiber 25 with a silicone resin or fluororesin 27. Since the silicone resin collects dust in contact therewith by the adhesive power, the dust quantity to be collected and the range of the size of dust to be collected are increased and collecting effect is enhanced. And, since the adhesive power of the silicone resin is recovered even after washing, the collecting effect is enhanced again after washing. On the other hand, since the fluororesin is easily electrified, it is capable of electrically attracting dust. And, the property being easily electrified is recovered by drying after washing. Then, the air filter is used any number of times by washing.

Abstract: PURPOSE:To monitor a fact that a medical treatment focusing acoustic wave hits the target part by constituting the device so that it can receive both an echo of a pulsatory ultrasonic wave transmitted by an ultrasonic transmitter- receiver and an even number fold harmonic signal. CONSTITUTION:In an applicator, ultrasonic transmitter-receivers 5-1, 5-2 are attached to a lesion to be cured, and also, an ultrasonic pulse echo image photographed by a transmitting-receiving amplifier, and a receiving beam scan is superposed and displayed as a two-dimensional tomographic image on a screen. Also, when the transmitter-receivers 5-1 and 5-2 are rotated, a double two-dimensional image is obtained within a range in which two conical areas are superposed. In the vicinity of a focus of an acoustic wave, an even number fold harmonic is generated. This signal is superposed on a pulse echo image and displayed. After confirming a fact that the harmonic generating position matches with the lesion, a regular irradiation of a focusing storing acoustic wave is executed. When it is shifted or a high frequency is small, the irradiation is executed again, while referring to the screen. In such a way, the medical treatment can be executed with high safety.

Patent JP-H03239165-A (JP)
Title: Inverter system
Inventor: KISHIMOTO NAOKAGE
IPC: H02M7/537
Filed: 1990-02-15
Abstract: PURPOSE:To prevent an excessive short-circuit current from occurring which is caused by simultaneous ON conditions of switching elements by letting the potentials at anode and cathode sides of a diode fall at the same speed or letting the potential at the cathode side fall faster than the one at the anode side when the switching element at the high potential side is turned OFF. CONSTITUTION:With an oscillation output VB at the level H, a switching element S2 is driven at a gate potential E4. As the switching element S2 moves to an ON condition, a potential VA at a point A and the voltage VS2 at both ends of the switching element S2 drop to a potential E. Nextly, when the switching element S1 turnes OFF, the voltage V2 becomes zero in a moment. With the switching element S1 OFF and the switching element S2 ON, an electric charge of a parasitic capacity C2 falls. The next moment, a capacity element C3 is charged. Consequently, the switching element S1 maintains the OFF condition. Afterwards, the switching element S1 maintains the OFF condition since a forward drop voltage is low.
