Title: Compressor for car air-conditioner
Inventor: DEGAWA TAKU
IPC: F04B39/00
Filed: 1984-02-08
Abstract: PURPOSE:To save energy by making an axial hole through the rotary shaft of compressor while flowing in/out refrigerant through a through-hole made radially against said axial hole thereby stopping excessive delivery of refrigerant under high speed rotation. CONSTITUTION:Under low rotation of shaft 71, refrigerant will flow smoothly from low pressure chamber 74 through four through-holes 75a, 75b and 75c, 75d (not shown) having diameter of 5phi made radially. Upon increase of rotation of shaft 71 to increase moving speed of through-hole 75a-75d, the flow speed of refrigerant at the inlet of through-hole can not catch up said moving speed thus to make thin the refrigerant flowing through an axial hole 72. Consequently, intake refrigerant is reduced substantially to lower the volume efficiency as the rotation increases. As a result, even in such compressor to be driven directly through rotation of car engine, the compressor will never deliver excessive energy under high rotation of engine resulting in elimination of useless energy consumption.

Title: Removing method for ammonia in exhaust-gas denitrating process
Inventor: SHIRAKAWA NOBORU
IPC: B01D53/56
Filed: 1978-02-22
Abstract: PURPOSE: To decrease NH 3  consumption and to reduce exhaust-gas-disposing cost in removal of unreacted NH 3  in exhaust-gas-denitrating process, by decomposing ammonium salt formed by fixing NH 3  with acidic gas to form NH 3 , and by reutilizing the NH 3  in denitration.  
     CONSTITUTION: NH 3  is injected into combustion furnace 1 exhaust gas contg. NO x  etc., so as to make the NO x  inactive at 870W1,095°C in a temp.-lowering tower. Excess NH 3  reacts with acidic gas such as HCl etc. contained in the exhaust gas to form ammonium salt, and is led through a heat exchanger 3 to a washing tower 5, where it is washed with water to form an aq. soln. The soln. is delivered through an exhaust water tank 6 to an evaporation-to-dryness apparatus 10, where ammonium chloride C etc. is recovered. The ammonium salt is heated to 300W500°C and is decomposed in a vaporizer 11 packed with solid CaO etc. to form NH 3  which is reutilized. The acidic gas is neutralyzed with CaO etc. The exhaust gas flowing out of the washing tower 5 is sent through a moisture-decreasing tower 7, dust collector 8 to a chimney 4. NH 3  consumption in this process is very little so that replenishment of NH 3  is also very little, hence exhaust-gas-disposing cost is reduced.

Title: Semiconductor optical amplifier and optical gate switch
Inventor: IMOTO KATSUYUKI
IPC: H01S5/042
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor optical amplifier whose switching speed is fast and whose polarization dependence is small and to provide an optical gate switch. SOLUTION: On a substrate 20, an active layer 34 whose cross sectional shape is nearly rectangular is covered with an upper-part clad layer 35 whose cross sectional shape is nearly inverted U-shaped. The upper-part clad layer 35 is covered with an oxide layer 26 and a polymer layer 27 which are at a low permittivity and at a low refractive index. As a result, a parasitic capacitance becomes small, and a high-speed switching characteristic is obtained. In addition, since the distribution of the light intensity in the thickness direction and the widthwise direction of the active layer 34 can be made nearly uniformly large, the polarization dependence of a semiconductor optical amplifier can be suppressed.

Title: Line error detecting system
Inventor: YOSHIMOTO KOJI
IPC: H04J3/14
Filed: 1987-02-02
Abstract: PURPOSE:To detect the error of a line, by inserting a parity check bit to a variable time slot when a stuff designation pulse designates a stuff in a stuff synchronous multiplex. CONSTITUTION:Respective variable time slot is invalidated when the stuff designation pulse designates the stuff, and is validated when it designates a non-stuff. And when the information of the varable time slot is spoiled by designating the stuff by the stuff designation pulse, parity check is performed by inserting the parity check bit at a reception side, and the error generated on the line is detected. Thus, since the parity check bit is generated at every channel unit and the parity check is performed at every channel unit at the reception side by sending it to an opposite device at the time of generating the stuff, it is possible to set the targeted bit of a bit error detecting source as a bit of transfer information itself.

IPC: B41J2/51
Filed: 1979-02-23
Abstract: PURPOSE:To provide stable type quality without environmental limitation in a dot printer using a pulse motor for feeding a type head by generating a type signal with a drive signal of the pulse motor as a standard. CONSTITUTION:A pulse motor 1 is driven, and the first type signal 2a is applied from a start signal generator 2 to a type solenoid 3 after the time t1 by the dirving signal 1a in phase A. The signal 2a is applied to a type timing signal generator 4, which thereupon applies type signals 4a2, 4a3... to the solenoid 3 at type timing time t2. Thus, a type head prints dots at every type timing time t2 upon energization of the solenoid 3. When the solenoid 3 is energized seven times energizations  2a, 4a2, 4a3...4a7 forming one carrier, the output from the generator 4 is stopped  by an energization times discriminator 5 to stop the operation of the solenoid 3.  Then, when the motor 1 is rotated, the type head prints similarly to the above.
