Title: Fuel pressure control valve
Inventor: YAMAZOE HIROSHI
IPC: F02M69/00
Filed: 1985-06-28
Abstract: PURPOSE:To improve pressure regulation accuracy while keeping a fuel pressure area small when fuel flow rate into a fuel chamber changes by determining fuel pressure according to only pushing pressure set within a back pressure chamber without changing pressure receiving area of a pressure receiving section. CONSTITUTION:Fuel comes through a fuel inflow pipe 7 into a fuel chamber 2. To a back pressure introduction pipe 10 is introduced the pressure at the downstream side of a throttle valve. Here, the fuel in the fuel chamber 2 is controlled to be under higher pressure than the pressure on the downstream side of the throttle valve by a pressure: a pushing force of a spring 9+ working rigidity of a bellows 4/ area A of a pressure receiving surface 4a of the bellows 4. Namely, when fuel pressure against the pressure receiving surface 4a of the bellows 4 exceeds the pushing load produced by both pushing force of the spring 9 and working rigidity of the bellows 4, the bellows 4 contracts in proportion to the exceeded amount and a movable valve 11 comes off from the opening section of a fuel outflow pipe 8 in proportion to the exceeded amount.

Title: Charging of coal into coke oven
Inventor: TANAKA HITOSHI
IPC: C10B31/04
Filed: 1990-05-31
Abstract: PURPOSE:To prevent leakage of dusts and gases and deterioration of tar quality by regulating the coal charging speed with reference to the inner pressure of a carbonization chamber of a coke oven and thereby controlling the inner pressure of the carbonization chamber. CONSTITUTION:The coal in hopper 2 is cut out by rotating a table feeder 5 and charged from a charging hole 11 into a carbonization chamber 12. The charging speed is controlled by changing the rotation speed of a motor 6. Pressure change in each chamber 12 is continuously checked, and coal charging speed is altered in accordance with its deviation from the standard pressure previously input into a standard pressure presetter 9. The rotation speed of the motor 6 is changed based on a calculation given by a controlling sequencer 8. In charging coal, the inner pressure of the oven is continuously measured. When it is higher than the preset standard pressure, the coal charging speed is decreased. When it is lower than the preset one, the charging speed is enhanced. Thus, the inner pressure of the oven can be kept in the capacity of a dust-collecting apparatus, so that the leakage of dusts and gases can be prevented and carry-over of coal into tar can be suppressed.

Title: Method of measuring chromaticity of color cathode-ray tube
Inventor: ASANO TOSHIRO
IPC: H01J9/44
Filed: 1987-06-10
Abstract: PURPOSE:To make it possible to measure chromaticity with a high accuracy by storing in advance in a memory the picture data as a reference white color value obtained by taking a reference white color light source with a TV camera and subtracting the stored value in the memory from the actual measurement of a color CRT. CONSTITUTION:Taking the picture of a reference white light source 11 and measuring the chromaticity of chromatic variance of a color TV camera 2 itself in advance, the measurement is stored in reference white color value memories 12, 13. When measuring the chromaticity of a color CRT 1, the chromaticity of the color CRT 1 to be measured is obtained by subtracting the chromaticity of the color CRT 2 itself using the stored values stored in the reference white color value memories 12, 13. The chromatic variance of the color CRT 2 itself is offset by subtracting the picture data of the reference white light source 11 of the color CRT 2 from the measurements of the color CRT 1 with the color TV camera 2. This makes it possible to measure the chromaticity with a high accuracy.

Title: Semiconductor laser device
Inventor: ISSHIKI KUNIHIKO
IPC: H01S5/223
Filed: 1985-06-28
Abstract: PURPOSE:To form a highly reliable semiconductor laser device, which is capable of high output operation, by making the thickness of an active layer thin only in the region in the vicinity of the emitting end surface of laser light, and keeping the thickness of an inner layer so that the deterioration does not become conspicuous. CONSTITUTION:The thickness of a semiconductor active layer in the vicinity of the emitting end surface of laser light is 0.04mum or less. The thickness of said semiconductor active layer in the region other than the vicinity of the emitting end surface of the laser light is larger than 0.04mum. The thickness of an inner active layer 4 is about 0.05-0.1mum. Then an oscillating threshold current value is small, and stable oscillation, which can maintain a fundamental lateral mode, can be carried out. Meanwhile, since an active layer 4a, which is formed on a ridge part is thinner than the inner active layer 4, the spread of the light, which is guided in this region, becomes large in the vertical direction of the active layer 4a. Therefore, the area of light emission is increased. Since the optical density at the emitting end surface of the laser light becomes small, the COD level at the emitting end surface of the laser light is enhanced.

Title: Air conditioner
Inventor: OKUYAMA YASUHISA
IPC: F24F1/00
Filed: 1984-07-11
Abstract: PURPOSE:To improve the temperature distribution during the cooling and heating operations by disposing a propeller type fan in the air outlet so that when the fan is rotated in one direction, the air is blown downward, whereas when it is rotated in the other direction, the air is blown horizontally. CONSTITUTION:When the unit 1 is operated, for instance, in the heating mode, a fan 15 is rotated in the normal direction. That is, the air taken in from an inlet 13 passes through heat exchangers 4, 5 by a heat exchanger fan 3, and the hot air passes through conduits 9, 10 to be blown out of outlets 7, 8. The blown hot air is directed downward to the living space by vanes 18 so that it may not stay under the ceiling 2. When the unit 1 is operated in the cooling mode, the rotation of the fan 15 is reversed. That is, the air taken in from the center outlet 13 passes through the heat exchangers 4, 5 by the heat exchanger fan 13, and the cold air passes through the conduits 9, 10 to be blown out of the outlets 7, 8. The blown cold air is directed horizontally to the proximity under the ceiling 2 by the vanes of the fan 15 rotating in the reversed direction so that the cold air blown out of the outlets 7, 8 may be directed to the underside of the ceiling 2, and the cold air having a larger specific gravity may descend to improve the temperature distribution.

Title: Exhaust device for two-cycle engine
Inventor: YONEZAWA SHIGEKI
IPC: F02B27/04
Filed: 1986-06-19
Abstract: PURPOSE:To prevent the aspiration of new charge into an exhaust pipe by forming plural resonance chambers closed at their downstream ends at a downstream end of an exhaust pipe containing an inner pipe therein, and inserting a tail pipe opening to the outside of the exhaust pipe into one of the resonance chambers. CONSTITUTION:When a piston 3 is lowered, and an exhaust port 5 is opened, a positive pressure wave of exhaust gas is propagated in an exhaust pipe 7 to reach an upstream opening end of a tail pipe 11 and resonance chambers 13 and 14. As the tail pipe 11 is opened at 15 to the outside, the pressure wave is inversely reflected at the upstream opening end of the tail pipe 11, and is changed into a negative pressure wave which is in turn returned to the exhaust port 5. On the other hand, as each downstream end of the resonance chambers 13 and 14 is closed, the pressure wave is regularly reflected to be returned to the exhaust port 5. A period of the positive pressure wave in the resonance chamber 13 is different from that in the resonance chamber 14. Accordingly, the adverse effect of the negative pressure to the exhaust port 5 may be suppressed in a wide range of engine speed by setting a shape and a size of the inner pipe 12 so that the positive pressure wave may cancel the negative pressure wave.
