Title: Memory module capacity discriminating system
Inventor: WATANABE KYOICHI
IPC: G06F11/10
Filed: 1995-02-10
Abstract: PURPOSE: To utilize memory with many kind of capacity without changing hardware or software by writing data on a leading address in memory capacity extension unit and judging that the memory is packed when no parity error is detected in readout. CONSTITUTION: The data 79H and zero that is the result of odd parity are written on the leading address 100000H in memory capacity extension unit. Then, the data on the same address 100000H is read out. At this time, when a parity bit shows zero i.e., no parity error exists, it follows that the memory of minimum 1MByte is packed on the addresses after the address 100000H. Then, the address 100000H of memory capacity extension unit 1MByte is added, and the data 79H and zero that is the result of odd parity are written on the address similarly. When the data on an address 200000H is read out and the parity error is generated, it follows that no memory is packed on the addresses after the address 200000H.

Title: Heat exchanger
Inventor: ISHIHANE KIYUUHEI
IPC: F28F1/40
Filed: 1983-02-16
Abstract: PURPOSE:To reduce the friction loss of a working fluid while cutting down processing cost by  forming a section corresponding to the single phase region of the working fluid in a bare pipe and forming only a section corresponding to two phase regions being accompanied by condensation or evaporation in a heat transfer pipe to which a spiral groove is processed. CONSTITUTION:A cross-fin tube type heat exchanger is mostly used as an air-refrigerant heat  exchanger in an air conditioner, a refrigerator, etc. When such a heat exchanger is used as a condenser, a vapor refrigerant at a high temperature and high pressure, which is discharged  from a compressor, flows into the heat exchanger as the arrow, and heat-exchanges with flowing air. There is the vapor single phase region 3, in which the vapor refrigerant is cooled, in  a heat transfer pipe 1, there is the gas-liquid two phase region 4 in which heat is exchanged  with condensation, and there s a liquid single phase region 5 in which the refrigerant is liquefied completely. When the heat exchanger is used as an evaporator, the refrigerant under the  state of two phase of a liquid and a gas through a decompression device flows into the heat  exchanger, exchanges heat, is evaporated, is brought to the state of vapor single phase and is  forwarded to the compressor. In said constitution, pipe spiral groove processing is executed  only to the two phase region being accompanied by condensation or evaporation, and regions  except said region are formed in bare pipes, thus reducing the friction loss of the fluid, then  cutting down processing cost.

Title: Control signal transmission system
Inventor: HAMANAKA TOORU
IPC: H04B3/46
Filed: 1982-02-17
Abstract: PURPOSE:To perform transmission to each repeating device securely at low cost through simple constitution, by sending out a DC signal with an optional polarity  from one terminal of each balanced couple of cores together with a control signal of optional frequency when bringing repeating devices arranged on a transmission line under the remote control of a terminal equipment side; CONSTITUTION:From a constant current source 14, a DC signal is sent out to between input terminals (c) and (d) of a balanced couple of cores 2. The terminals of the balanced couple of cores 2 are looped, so the sent DC signal flow through Zener diodes 6 and 7 of each control signal output circuit in series. When the polarity of the input terminal (c) is positive, the voltage across the Zener diode 6 is a Zener diode of, for example, about 5 V and the voltage across the Zener diode 7 is a forward voltage of about 0.7V. Voltage detecting circuits 8 and 9 do not operate by the forward voltage, but operate by the Zener voltage, so only the voltabe detecting circuit 8 outputs a voltage detection signal (g) and a voltage detection signal (h) is not outputted. An AND gate 10 is therefore opened to output a control signal (e) as the 1st control signal (j) through the AND gate 10.

IPC: H05H1/32
Filed: 1991-02-18
Abstract: PURPOSE:To move arc discharge in stable state by changing the inter-electrode distance through repetition of inclining a discharge electrode, inserting a plate in the flow path for a thermo-medium, and moving it periodically in the longitudinal direction of electrodes. CONSTITUTION:When current is fed from a power supply 10 to electrodes 1, 2, an arc current is generated between the electrodes, and heat plasma is produced in a thermo-medium gas flowing in the space between them 1, 2. Thus a plasma jet is obtained. When current is fed to either of the piezo elements 4 and the electrode 2 is inclined relative to the other 1, the electric field is inclined to cause the arc current to move toward the intense side of electric field. An insert plate 7 is installed on the way of an influx hole 9 for the thermo-medium gas to constitute a baffle plate, and thereby a low pressure part is generated locally in the space between the electrodes 1, 2, so that the arc current moves in the direction of generating stable state of electric discharging. Current feed to piezo element 4 is repeated periodically, and the electrode 2 is swung relative to the other 1, and interlockingly the insert plate 7 is moved periodically. At this time, the arc current becomes equivalent to the plane arc state at the electrodes 1, 2, and the thermo-medium gas is heated to cause emission of a plane plasma jet.

Abstract: PROBLEM TO BE SOLVED: To simplify the structure of a pad spring for energizing a friction pad by applying the constitution that the friction pad before operating a disc brake is preliminarily assembled with a caliper body nearer a disc turning-out or turning-in position. SOLUTION: The pin holes 14c and 14c of a back plate 14 are formed to be oblong and both of the pin holes 14c and 14c are arranged at the same inclination angle with both edges of the disc turning-in and turning-out sides of the back plate 14. Also, a friction pad 4 suspended from hanger pins 11 and 11 is sprung toward the disc radial inner side with a pad spring 12. A part of the springing force of the pad spring 12 toward the disc radial inner side acts on the friction pad 4 as a component force along a disc turning-out direction, in relation to the shape and inclined arrangement of the pin holes 14c and 14c. Thus, the friction pad 4 moves toward a disc turning-out direction as well, pushed toward the disc radial inner side, while the pin holes 14c and 14c having an inclined shape slide on the hanger pins 11 and 11.  At the same time, the disc turning-out side edge 14e of the back plate 14 comes in contact with a torque receiving surface 3g at the disc turning-out side without any gap.
