Title: Optical reproduction repeater
Inventor: TAKANO ISAMU
IPC: H04B10/079
Filed: 1990-03-27
Abstract: PURPOSE:To almost eliminate accumulation of jitter and to improve the characteristic of an optical reproduction repeater by extracting a timing component of an input optical signal and inputting the component to an optical latch circuit as timing information of optical latch processing. CONSTITUTION:An input signal is subject photoelectric conversion by a photodetector circuit 106, and a timing line spectrum component is generated in a differentiating circuit 108 and a full wave rectifier circuit 109. A timing signal extracted by a timing tank circuit 110 is subject to tuning and amplification at a narrow band amplifier 111 and the result is outputted to a timing current supply circuit 112. An optical latch circuit 104 applies identification processing of an optical signal inputted from an optical semiconductor amplifier 102 by the timing current fed from the timing current supply circuit 112. Thus, since the optical latch processing is implemented by using the highly stable timing signal with less timing jitter, the accumulation of jitter or the like is almost eliminated and the characteristic as the optical reproduction repeater is improved.

Inventor: UEDA SEIICHIRO
IPC: F23G7/00
Filed: 1988-03-31
Abstract: PURPOSE:To manufacture a solid combustion improver which does not lower the processing efficiency of a substance to be processed in a waste melting furnace, by a method wherein after combustible waste is crushed, the waste is heated and molten by utilizing plastic in the waste serving as a binder while the waste is compressed so that an apparent specific gravity is made to a value similar to that of ash or dried sludge to form pellets. CONSTITUTION:After bulky refuse or a substance unsuitable for incineration, containing plastic, in collected refuse is crushed by a crusher 5, the crushed refuse is classified into a combustible substance and an incombustible substance by means of a primary magnetic selector 6 and through a selecting process 7. The incombustible substance is fed to a waste melting furnace 4, while the combustible substance is separated from iron by a secondary magnetic selector 8, and the rest is compressed by a biaxial extrusion molder 9 so that an apparent specific gravity is made to a value similar to that of incinerated ash, and is cut as it is extruded through a dice plate at a tip to form the waste in a pellet-form shape. The pellet-form substance thus obtained is fed as a solid combustion improver to the waste melting furnace 4 together with the incinerated ash. In the biaxial extrusion molder 9, plastic in the combustible substance is molten by a friction heat and performs a role of a binder.

Title: Cold-regenerative refrigerator
Inventor: YAMADA KOJI
IPC: F25D11/00
Filed: 1988-03-31
Abstract: PURPOSE:To lower the temperature of the cold-regenerative material at the end of the time zone for a cold-storing operation by repeating a cold-storing run by shifting the passage for refrigerant to the one for cold-storing evaporator when a temperature sensor finds the temperature of the cold-regenerative material to be above a prescribed temperature even after completion of a cold storing. CONSTITUTION:On a day's time schedule of the operating mode of a cold-regenerative refrigerator, starting the operation at 10.00 p.m. in an unbroken time zone from B2 to B1, the refrigerator alternates an ordinary cooling run with a cold-storing run, that is, while maintaining the storage space temperature at a constant point by ordinary cooling runs, the refrigerator stores cold by cold-storing runs. To store cold, a solenoid valve for cold storing 15 is opened, whereas a main solenoid valve 9 is closed, and a liquid refrigerant is fed to a cold-storing evaporator 19 by driving a compressor 1. When, as a result of cold-storing runs, a cold-storing evaporator sensor 33 finds that the temperature T of the cold-regenerative material 18 has touched a point T1 signifying completion of the cold storing, for example, -29 deg.C, the operation shifts to the ordinary cooling; however, when the temperature T of the cold-regenerative material 18 has risen to T2, for example, -26 deg.C, even during the ordinary cooling operation, the cold-storing operation is resumed and continued until the temperature T of the cold- regenerative material declines to -29 deg.C again.

Title: Microwave transmission line
Inventor: KIKUCHI TOSHIO
IPC: H01P1/00
Filed: 1979-06-27
Abstract: PURPOSE:To constitute a microwave transmission line easily without exerting an influence of blow holes residing in a metal supporting plate by inserting and supporting in the through hole of a metal base body while it penetrates a dielectric support body equipped with a circumferential conductor. CONSTITUTION:In center holes 13 of dielectric supporting bodies 10 inserted into a through hole provided in metal supporting body 1, a molded body manufactured by die casting, input terminals 4 and 5 derived from microwave module 3 are inserted and supported being fixed by dielectric substrates 6 and 7. As a result, even when blow holes 8 reside in metal supporting plate 1, the characteristic impedance depends upon the ratio of outer diameter a5 of output terminal 5 to inner diameter b5' of metal tube 12 by the metal tube 12 provided on the outer circumferential surface of cylindrical dielectric 11, so that the impedance will not be changeable due to the existence of blow holes 8.

IPC: G05D23/00
Filed: 1978-07-04
Abstract: PURPOSE: To provie a temperature adjusting apparatus, wherein water temperature of a boiler which supplies warm water to an object the temperature of which shall be adjusted is controlled in accordance with change of circumstances surrounding the object, such as ambient temperature, an ammount of sunshine, etc., so that crops grown in a green house, etc. will be provided with optimum circumstances.  
     CONSTITUTION: The value of resistance of a thermistor 19 is varied according to ambient temperature to energize the output of a comparator 21. For instance, when ambient temparature is lowered, a transistor 22 becomes conductive by the output of the comparator 21 to close the relay 24. As a result a burner 26 of a boiler is ignited by a power source 25 to increase the temperature of water of the boiler. The warm water of the boiler is fed into a room through a valve 13. The water temperature of the boiler is detected by a thermistor 20, and by the output of the thermistor 20 a relay 23 is deenergized to extingush firing of the burner 26.

IPC: G03G21/00
Filed: 1989-04-03
Abstract: PURPOSE:To stabilize the quality of the image of a 1st sheet by inverting the bias polarity of a developing roller, etc., with the input from a copy start detecting means which detects the start of the copying of the 1st sheet in a stop state. CONSTITUTION:A control means 2 commands a high voltage power source 11 to invert the polarity of a bias applied to a developing roller 4, a developing blade 5, and an electrostatic discharging brush 9 with the input from the copy start detecting means 1 which detects the copying start of the 1st state in the stop state. The control means 2 inverts the polarity of the applied bias voltage at the timing of the detection of a home position marker by the copy start detecting means 1 and returns the polarity of the applied voltage to the normal polarity right (about 0 - 3 seconds) before the head end of an electrostatic latent image formed on a photosensitive body contacts the developing roller 4. Consequently, the solid black blur and ground staining of the copy image of the 1st sheet can be reduced to nearly the same extent with 2nd and succeeding sheets.
