Title: Suction device for engine
Inventor: HITOMI MITSUO
IPC: F02B29/08
Filed: 1985-03-01
Abstract: PURPOSE:To bring out a suction inertia effect to the full, by altering the closing timing of a suction valve so as to become quicker than that at the time of high speed when an engine is slow, in case of a device which advances the timing of opening a timing valve according to the engine speed. CONSTITUTION:A suction passage 13 is provided with a common passage 14 extending out of an air cleaner and an independent passage 16 leading to a suction port of each cylinder 2 from a surge tank 15. and, this independent passage 16 is fitted with a timing valve 17 which is designed so as to be mechanically driven by a crankshaft 5 via a timing control mechanism 19. In this case, this timing control mechanism 19 alters its timing advance value according to an engine speed. Therefore, an actuator 27 for driving an adjusting block 26 of this timing advance mechanism 19 is operated by a control unit 28 where the engine speed is inputted. And, in proportion as the engine speed grows larger, its timing control is advanced, whereby a timing lag of opening the timing valve 17 to the timing of opening the suction valve 7 is reduced.

Title: Digital camera
Inventor: HIROMATSU KENJI
IPC: G03B7/22
Filed: 1995-02-28
Abstract: PURPOSE: To provide an inexpensive digital camera in which the color temperature can be easily and precisely corrected. CONSTITUTION: A graph data showing the state in which the ratio among three primary color RGB signals Rs, Gs, Bs outputted from an image pickup device is changed to the change of the color temperature of an illuminating light source, is preliminarily stored in a reference table 175. When a measured first color temperature data and a desired second color temperature data are inputted, a CPU 173 calculates the correction coefficient of color temperature in reference to the graph data, and sets it to a correction coefficient resistor 176. Multiplying circuits 171-173 multiply each correction coefficient set in the correction coefficient resistor 175 to the three primary color RGB signals Rs, Gs, Bs, thereby, the output ratio among the three primary color RGB signals is corrected.  Thus, three primary color RGB signals Rt, Gt, Bt having a desired color temperature are outputted form the multiplying circuits 171-173. The color temperature can be thus corrected without using a special correction filter.

Title: Nonvolatile semiconductor memory device
Inventor: YOSHINOGAWA KUNIO
IPC: G06F12/16
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To improve reliability of data written with the use of a PROM writer in a PROM(programmable read only memory) built in an ECC(error-correcting code) circuit, similar to a general PROM. SOLUTION: When an error-detecting circuit 3 detects an error from a main PROM cell 1 or parity PROM cell 2 and at the same time, a verify mode- detecting circuit detects that a verify mode is set at present, a different data- generating circuit generates data different from data supposed to be written. Therefore, the presence/absence of errors in the main cell and parity cell can be detected simply by verifying in the same manner as when a PROM is generally verified. The verification at, the write time makes it possible to use the ECC circuit solely to correct a change of data after being written. An error correction rate to the data change is consequently increased, thereby enhancing reliability of data.

Title: Car air conditoioning device
Inventor: YAMAZAKI TSUTOMU
IPC: B60H1/00
Filed: 1984-03-06
Abstract: PURPOSE:To prevent production of a difference between the temperature of a car room and a set temperature, by a method wherein the rotary lever of an air mix door is coupled to the slider of an opening sensor so that the slider is movable depending on rotation of the rotary lever. CONSTITUTION:The upper end of a resistance adjusting lever 12b of a door opening sensor 12 is slid over a register 12a as the upper end is slipped in an obling hole 26 along with rotation of an air mix door shaft 16 and through rotation of a rotary lever 26 secured to the door shaft, and this varies a resistance value. Namely, the resistance adjusting lever 12b is moved in response to the opening of the air mix door, and thereby no influence is exercised by divergency, occuring to a link system, on relation between the opening of the door 7 and the moving distance of a servo shaft. Namely, mounting adjustment of a power servo is simplified. This permits the opening sensor 12 to reliably detect the opening of the air mix door, resulting in coincidence of the actual opening of the door with a desired opening to bring the temperature of a car room into a desired opening to bring the temperature of a car room into a desired set temperature.

Title: Starting method of pump or pump water-wheel
Inventor: MORII TAKAOMI
IPC: F03B15/04
Filed: 1980-03-31
Abstract: PURPOSE: To prevent the influence of the contact between the surface of water and the runner vane onto the main machine, by maintaining the water level of a suction tube below the setting level between the interval from the start to the completion of the water filling into the spiral casing.  
     CONSTITUTION: When starting a pump water-wheel, a bypass valve 8 is opened and the water is supplied from a guide tube 7 into a spiral casing 1. At the time point when the water filling into the casing is completed, the casing pressure and the centrifugal force of water in the runner 5 are balanced thereby the water in the spiral casing 1 is pushed against a runner chamber 3 and the outer-circumference of the runner 5 in hollow cylindrical shape to form a water pillar thereby the water isn't filled any more from the casing side to the runner 5. Consequently the surface of water in the suction tube 10 doesn't contact with the vane of the runner 5 thereby the main machine isn't influenced.

Abstract: PROBLEM TO BE SOLVED: To efficiently treat a cylindrical work by dipping without adhering adhesives to jigs. SOLUTION: The work 2 consisting of a magnetic material is attracted to the jig 1 with magnets (stage A). The work 2 is put into the posture hanging downward from the jig 1 and only the lower half part thereof is dipped into a liquid tank 5 (stage B).

Filed: 1990-02-26
Abstract: PURPOSE:To improve the reliability and to reduce the loss and to miniaturize the optical demultiplexing circuit, by coupling plural linear waveguides for input and output with plural optical waveguide circuits for wavelength separation. CONSTITUTION:A directional coupler 13 demultiplexes only monitor light be tween signal light and the monitor light which are both made incident on a main waveguide 2, couples it with a loop-back waveguide 4 being a 3rd optical waveguide. The directional coupler 14 couples the monitor light which is guided by the loop-back waveguide 4 with the main waveguide 3. The monitor light is therefore demultiplexed from a 1st optical waveguide 2 to a 3rd optical waveguide 4, then coupled with a 2nd optical waveguide 3, and projected from the input port of the 2nd optical waveguide 3. The signal light, on the other hand, is propagated in the 1st optical waveguide from one port to the other port. Consequently, the reliability, productivity, size and weight reduction are improved.
