IPC: H02M7/48
Filed: 1988-12-21
Abstract: PURPOSE:To decrease the peak current and the heat loss by increasing the frequency of a carrier wave within a specific angle centering around a peak current point. CONSTITUTION:An electrical angle from the zero point of a voltage command signal to the peak current is found from the power factor angle of AC power transmitted by a PWM inverter 1 and an electrical angle of the output current of said inverter 1 starting from the zero point thereof and reaching the positive or negative peak value. The frequency of a carrier wave within a specific angle centering around the peak current is set higher than that out of the specific angle. Thereby the peak current and the heat loss can be decreased.

When the top mold 1 and the bottom mold 2 reach predetermined temperatures, a rubber material is set up on the bottom mold 2 so as to retreat the bottom mold 2 to a predetermined position in order to raise the bottom mold 2 together with a guide member 11 by means of an elevating device 5 for clamping the molds and then vulcanizing-molding the rubber material and finally a resultant molding is unloaded by moving the bottom mold 2 forwards. After that, the next rubber material is set up on the bottom mold 2 so as to repeat the above actions in order to perform its vulcanizing molding. Thus, the temperature lowering of the bottom mold 2 is prevented from occurring and the necessity of its re-heating and time loss are solved and the working efficiency of the vulcanizing molding and the quality of the molding are improved and the poor molding due to the lowering of the temperature of the bottom mold 2.

Title: Video signal processing circuit
Inventor: HANAGATA TAKUSHI
IPC: H04N9/04
Filed: 1995-11-20
Abstract: PROBLEM TO BE SOLVED: To prevent the output of an integration signal including a false chrominance signal even when a vertical edge exists by stopping the integration operation of a primary color integration circuit at the time of detecting the level of a vertical edge signal which is higher than a threshold level. SOLUTION: The integration operation of the primary color integration circuit 3 is controlled by a comparator 2. To one side of the comparator 2, the vertical edge signal is inputted and to the other, the threshold level is inputted. When the level of the vertical edge signal becomes higher than the threshold level, the comparator 2 outputs a stopping signal for stopping the integration operation of the primary color integration circuit 3. Thereby when there is a fear that a primary color separation circuit 21 generates a false chrominance signal because the level of the detected vertical edge signal is high, the integration operation of the primary color integration circuit 3 is stopped to prevent the primary color integration circuit 3 from integrating the false chrominance signal. Consequently, a microcomputer supplied the integration signal from the primary color integration circuit 3 calculates color temperature of satisfactory accuracy.

Title: Magnetic card handling device
Inventor: KANO YOSHIAKI
IPC: G06K13/06
Filed: 1988-12-23
Abstract: PURPOSE:To return a magnetic card left behind by a customer and recovered to the internal part of the title device by confirming card taken out of a recovering part one by one and returning a card to coincide with a customer request command to a card taking in/out port. CONSTITUTION:When a return request is received for a magnetic card 14a in a first recovering part 18, magnetic cards 14a are separated and sent backward to a card temporary holding part 11 one by one by a separating roller 16 to be driven by a motor. Further, each magnetic card 14a is sent to a magnetic stripe reading part 3 by the rotation of a motor 8, and the data content of the magnetic card 14 is read again. When the read data and data inputted by the customer are noncoincident, the magnetic cards 14a in the first recovering part 18 are carried to the magnetic stripe reading part 3 one after another, and the carrying of the magnetic cards is repeated until the magnetic card 14 for which the customer sent the return request is selected. Thus, the genuineness of the magnetic card 14 recovered in the device can be confirmed and returned in a short period without necessitating a direct operation by a person in charge.

Title: Heat exchanger for compressor
Inventor: NISHIMURA HITOSHI
IPC: F04C29/04
Filed: 1989-12-15
Abstract: PURPOSE:To use different materials properly and precisely so as to reduce the manufacturing cost and the thermal stress of a heat exchanger for a compressor by forming low-and high-temperature side cooling pipes from different materials, the cooling pipes each connected between the inlet and outlet portion headers of the heat exchanger. CONSTITUTION:In a pre-cooler serving as a heat exchanger forming one part of the delivery system of an oil-free screw compressor, high-temperature compressed air allowed to flow into an inlet portion header 7 is heat exchanged with cooling air and cooled in a high-temperature side cooling pipe 8 and is then cooled in a low-temperature side cooling pipe 9 and transferred from an outlet portion header 10 to an after cooler. In this case, the cooling pipes 8, 9 are made from different materials; e.g., the high-temperature side cooling pipe 8 is made from stainless and the low-temperature side cooling pipe 9 from copper. A low-cost material (e.g., copper) is thus employed on the low temperature side of the pre-cooler so as to reduce the manufacturing cost of the pre- cooler. Also, the amounts of thermal expansion of the high-and low-temperature sides of the pre-cooler are maintained equal to each other so as to reduce the thermal stress.

Abstract: PURPOSE:To measure or command any station from a certain station by applying data measuring ability and storage ability in an accident time or a current state to the all stations. CONSTITUTION:Each station has the ability to decode the storage and command of the data and to operate conforming to the command and transmitting and receiving ability. When the command to collect the total data from a No.1 station to a No.5 station in to the No.1 station is issued, the No.2 station is accessed from the No.1, and the reception of the command of the total data requests is transmitted. The No.2 accesses the No.3, and the command of the total data requests is transmitted. In the same way as above, the command of the total data requests is transmitted to the last No.5. The No.5 transmits the total data stored into a memory to the No.4. The No.4 stores the data to the memory, and transmits it to the No.3 together with the data of the No.4. In the same way as above, the data of the No.5 4, 3 and 2 are transmitted to the No.1. Thus, when the command of the total data requests is issued to the final station at the beginning and the transmission is started, only the data are sent and the command is not sent.
