Abstract: PURPOSE:To invariably copy a high-quality image by accurately correcting the transfer current without causing impediments such as a transfer miss and a transfer cissing in an electrophotographic copying device in the high-humidity high-temperature state. CONSTITUTION:An electrophotographic copying device is provided with a history memory means of the output value change from a humidity detecting means, a measurement memory means of the stack period of transfer sheets in a transfer sheet cassette, and a mechanism changing the control based on the memory value and the number and sequence of the transfer sheets stacked in the cassette. The change of the moisture content of the transfer sheets with the lapse of time while they are stacked in the cassette is stored as the exponential function, and the corona discharge output of a charge unit is programmed to follow the optimum value according to the exponential function. The time constant is changed at the time of moisture absorption and at the time of moisture desorption to cope with the control. The last humidity measured data are stored when a power source is turned off, the data are compared with the humidity measured data when the power source is again turn on, and moisture absorption and moisture desorption are automatically selected.

Title: Laser diode
Inventor: TAKAHASHI HIDEO
IPC: H01S5/026
Filed: 1990-03-05
Abstract: PURPOSE:To enable a laser diode to be elongated in service life and improved in reliability by a method wherein two laser diode chips, a monitoring PIN photodiode, and an integrated circuit in which an FET input type differential amplifying circuit and a switching MOSFET are integrated are mounted in the same package. CONSTITUTION:A PIN photodiode 3 is made to function as a monitoring photodiode for both an LD1 and an LD2 and to generate an input voltage to an FET input type differential amplifier 7 in a later stage. When the LD1 deteriorates in optical output, the monitored voltage also decreases. When the monitored voltage decreases to be lower than a reference voltage, the output of a differential amplifying circuit is turned HIGH in level to put a MOS FET8 in an ON state, and the circuit of the LD2 circuit is automatically closed to drive the LD2. In result, the LD2 is driven after the LD1 is driven, so that a laser diode of this design can be elongated twice as long in serve life as a conventional one.

Filed: 1989-03-07
Abstract: PURPOSE:To form a fine spot on an optical disk without using an external lens such as a cylindrical lens by providing a taper-like waveguide constituting the main part of an optical head with convergency. CONSTITUTION:Waveguided light 6 arriving at a waveguide lens 7 goes convergent light converging in the width direction of a waveguide layer 1 by the convergent action of the lens 7 and then goes a beam converging upon a focus 8 in air. Namely, the waveguided light passing the lens 7 arrives at the taper part 4 of the taper-like waveguide layer while gradually narrowing the beam width and is projected as leaked waves to the bases 2, 3 by the action of the taper part 4 and then projected from the end face 5 of the projecting base 3 to the outside. Then the projected light 9 is provided with the convergency of an (x) direction component by the action of the taper part 4 and the action of the bases 2, 3 and goes a beam converging upon the focus 8. Since the projected light 9 projected to the outside goes projected light converging in the (x) and (y) directions, a fine optical spot can be formed on the focus 8 in air.

Abstract: PURPOSE:To compose a semiconductor switch circuit with high dielectric strength of transistors (TR) with general dielectric strength by connecting TRs having the same polarity in series, using their emitters as switch terminals, and driving their bases by a driving circuit. CONSTITUTION:The emitter of an NPN transistor TR1 is regarded as a switch terminal 102 and its collector is connected to an NPNTR2, whose emitter is grounded. The output terminal 103 of the driving circuit 7 consisting of PNPTRs 3 and 4 and an NPNTR5 is connected to the base of the TR1 and the power source of the circuit 7 is connected to a power source VCC through a diode D6.

Abstract: PURPOSE:To obtain ingredients for rice, etc., which can be used easily and satisfactorily without necessitating preparatory treatment in the home, by cutting food raw materials such as meat, fish, shellfish, fresh vegetables, etc. to a proper size, frying in oil for a short time to effect the dehydration at the surface, and freezing the product. CONSTITUTION:Food raw materials such as meat, fish, shellfish, its processed product, and fresh vegetables, etc. are cut to proper size, and the cut raw materials are properly combined together and fried in oil one meal at a time or collecting several meals, or the individual raw material is fried separately, and packed in an amount of one meal or several meals. When the frying is carried out under the condition to penetrate the heat and the oil to the core part of the raw material, the original character of the material is lost, and accordingly, the materials should be fried under the condition to effect the thermal dehydration of only the surface layer of the material and to form an oil film to the surface. Ingredients of noodles, rice, etc. which can be used easily without necessitating the preparatory treatment in the cooking at home can be obtained without causing the freeze denaturation and the rapid deterioration after thawing.
