Title: 2/4 wire conversion circuit
Inventor: OMIYA MASARU
IPC: H04Q3/42
Filed: 1989-06-16
Abstract: PURPOSE:To improve a signal level outputted to a line side with a single power supply by using an intermediate potential obtained through the connection of a serial resistor between ground and a single power supply used for the power supply of an amplifier as a reference voltage for the amplifier and the bridge. CONSTITUTION:A single power supply +V is used for the power supply for an amplifier OP1 sending an input signal from a bridge circuit 24 and an amplifier OP2 outputting an output signal to the bridge circuit 24 and two resistors R10, R11 are connected in series between the single power supply +V and ground. Then an intermediate potential is obtained at their midpoint and the intermediate potential is used as a reference voltage for the bridge circuit 24 and the 1st and 2nd amplifiers OP1, OP2. Crosstalk is eliminated by using the signal power supply +V in this way to improve the leve of an output voice signal.

Title: Multi-tube type heat exchanger
Inventor: MORITA TOMONARI
IPC: F28D1/053
Filed: 1995-05-30
Abstract: PURPOSE: To reduce a possibility that brazing material flows along a boundary between a fin and a pipe by a method wherein a pair of opposing tanks are connected by a plurality of heat transfer bodies mutually while the boundary between the pipe and the fin of the heat transfer body is not abutted against the surrounding walls of the tanks. CONSTITUTION: A pair of opposing tanks 2 are connected mutually by a plurality of heat transfer bodies 3. The end surface of the fin 3b of the heat transfer body 3 is not abutted against the surrounding walls of the tanks 2 or a boundary between the pipe 3a and the fin 3b of the heat transfer body 3 is not abutted against the surrounding walls of the tanks 2 whereby possibility that brazing material flows along the boundary between the fin 3b and the pipe 3a from the surrounding walls of the tanks 2, on which the film of the brazing material is formed, is reduced when the assembled body of constituting members is heated in a furnace to connect them through brazing.  Accordingly, problems such as spoiling of the appearance, increasing of air passing resistance during using, invasion of silicon constituent in the brazing material due to the diffusion of the same and the like will never be generated.

Title: Analog output device
Inventor: MOURI OSAMU
IPC: H03M1/66
Filed: 1981-09-29
Abstract: PURPOSE:To obtain two types of analog output modes simply, by providing an MDB signal switching circuit switching an output in response to an output mode designating bit given from an upper-stage device. CONSTITUTION:When a mode designation bit MDB given from an upper-stage device is zero, a switching circuit 21 outputs the most significant bit MSB of a digital data CPUDATA to a digital/analog converter DAC 11 as it is. Since a driver circuit 23 turns off or on transistors Q1, Q2 in response to the MDB= ''0'', an output of a buffer amplifier 22 is reduced to 0 volt and a positive voltage corresponding to a DACDATA using 0V as a reference is obtained from a buffer amplifier 12. When the MDB=''1'', the level inversion signal of the MSB signal is outputted to a DAC 11 as the MSB signal of the DACDATA to respectively turn on and off the Q1, Q2, and an offset voltage is outputted from the amplifier 22 and an analog signal using this voltage as a reference is obtained.

Title: Method of driving pneumatic actuator-unit of speed change gear
Inventor: SESHIMA TATSUYA
IPC: F16H61/32
Filed: 1986-07-01
Abstract: PURPOSE:To prevent a state, in which speed control becomes impossible, by supplying air to both pressure operating chambers so that the piston takes the neutral position, exhausting the air from both pressure operating chambers and then supplying throttled air to one of the operating chambers. CONSTITUTION:Pressure operating chambers 14 and 15 are connected to directional control valves MVA, and MVB. Both chambers 14 and 15 are also connected to a pressurized air tank 72. A speed control valve MVS, when it is turned on, throttles the air via an orifice 73 so that an actuator speed becomes controllable. When the actuator is in operation, the directional control valves MVA and MVB are turned on, and the piston is moved to the neutral position. Next, after an interval of, for example, 50ms during which time both valves are kept turned on, both valves MVA and MVB are turned off. Then, after an interval of, for example, 100ms, the air in the operating chamber is discharged, thereby turning the pressure in the chamber into the atmospheric pressure. Next, the speed control valve MVS is turned on, and supply of throttled air to the pressure operating chamber 14 is started. At the same time, the directional control valve MVA is turned on, and the piston 11 is moved leftward. Accordingly, the throttled air can be supplied to one of the pressure operating chambers 14 and 15, after the air in both chambers has completely been discharged.
