Title: Printing timing detecting system for laser printer
Inventor: KITAGAWA SHUNJI
IPC: G03G15/04
Filed: 1988-02-17
Abstract: PURPOSE:To correctly detect a writing position in case of printing with the low quantity of light and to effectively maintain a printing quality by setting a laser beam to a high level only at the writing start position. CONSTITUTION:When a prescribed voltage is impressed to a transistor 3 from a driving voltage supply part 4, a current passes to a semiconductor laser 1 and the laser beam is emitted. A photodiode 2 incorporated in a laser 1 detects the quantity of laser beam, feeds back to the driving voltage supply part 4 through a level detecting part 5, a light output level deciding part 6 or 11, a light output control part 7 or 12 and a driver amplifier 8 to maintain the laser beam output to a constant value. During a period when the laser beam is projected on a photosensor (not shown) disposed correspondingly to the writing start position and the vicinity thereof, a timing signal B goes to H to change over switching means 10, 13 to (b) side and set the light output to a high level V2. Then, the output of the photosensor is increased to improve S/N, so that, the writing start timing can be correctly detected to effectively maintain the printing quality.

IPC: G03G15/08
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To form a high quality image even in the case of controlling development bias voltage by providing an image density control part which controls the development bias voltage and a toner supply bias voltage. SOLUTION: A development bias voltage control part 29 is connected to a development bias voltage supply power source 12 and a toner supply bias voltage supply power source 26, and, further, the image density control part 28 is connected to a development bias voltage control part 27 and a toner supply bias voltage control part 29. By manually inputting data through a console panel, the image density control part 28 changes the output voltages of the development bias voltage supply power source 12 and toner supply bias voltage supply power source 26 and thus can change image density in seven levels. At this time, the output-voltage difference between the development bias voltage supply power source 12 and the toner supply bias voltage power source 26 is controlled to a specific voltage difference.

Title: Control of flow rate of moisture-containing fuel gas
Inventor: FUJIWARA TOSHIHISA
IPC: G05D7/00
Filed: 1979-03-27
Abstract: PURPOSE: To exactly measure and control the flow rate of moisture-containing fuel gas at all times even when the moisture content of the gas fluctuates, by controlling the flow rate by transmitting to an arithmetic unit the moisture content of the fuel gas measured at downstream of an orifice placed in the control line.  
     CONSTITUTION: The flow rate of fuel gas passing through a pipe 1 is determined by an arithmetic unit 4 to which a pressure difference across an orifice 2, measured by a differential pressure transducer 3, gas temperature 5, gas pressure 6 and, in addition, a moisture content 10 measured after the orifice are transmitted as input signals. This measured flow rate is exact because it is determined with the consideration of the actual moisture content of the fuel gas. Accordingly, the calorific value required for a given use is always properly supplied. On the other hand, when the fuel gas is saturated with water vapor, the water content 10 is determined from the manipulation of the gas temperature 5, and the value is transmitted to the arithmetic unit 4. Also by this method, the calorific value of the fuel gas can be exactly determined.

Abstract: PURPOSE: To make the pickup of a core after casting easy and produce a hollow steel ingot of superior inside surface characteristics by constituting the core material of a core and the outer side thereof with a refractory material deposited layer by an org. binder in casting the hollow cast ingot by using a mold and a core.  
     CONSTITUTION: A core is disposed in the central part of a mold concentrically to the mold, and molten metal is poured between the mold and the core, whereby a hollow steel ingot is cast. In this case, a coating layer 42b of fine particulate or fibrous refractories SiO 2  or Al 2 O 3  alone or in combination using 4W8% an org. binder such as furan-urea resin or furan phenolic resin is formed on the outside circumference of the core material 41b of a core 4b. Or further, a coating layer 43b in which the above-mentioned refractories are hardened by an inorg. binder such as water glass contg. 28% sodium silicate is formed on the outer side thereof. At the casting, the org. binder burns by the heat of the molten metal and the refractories reduced to ash; therefore, the core after the casting is picked up easily in the core material part, and the hollow steel ingot having superior inside surface characteristics of the hollow hole is produced.

Title: Thin inductor/transformer
IPC: H01F27/28
Filed: 1992-02-24
Abstract: PURPOSE:To raise an inductance and to reduce a temperature rise in a thin inductor/transformer which is formed by piling up a spiral plane coil, an insulating film and a magnetic film on an insulating substrate. CONSTITUTION:An oxide soft magnetic material of large permeability and saturation density is applied to an insulating substrate 1 and/or insulating films 4a, 4b. An oxide soft magnetic material of high electric resistance and small power loss is used for magnetic films 5a, 5b. Since magnetic resistance thereby lowers and magnetic flux density rises in an area near a central part and an area near an outermost side part of spiral plane coils 2a, 2b, an inductance rises. Furthermore, heat generation due to eddy current loss at high frequency is reduced and a temperature rise is reduced by using the oxide soft magnetic material for the magnetic films 5a, 5b instead of a metallic soft magnetic material.

Title: Compression reduction volume treating method of waste solid
Inventor: UEHARA MINORU
IPC: G21F9/00
Filed: 1988-02-19
Abstract: PURPOSE:To contrive not to disperse final waste body by latent stress even if the corrosion of a casing such as drum can and the like of outer sheathing produces after burial by compression molding organic substances in which solid waste is contained after they are cooled down to brittle temperature or less together with a vessel. CONSTITUTION:Solid waste 1 is put in a vessel 2 like a basket of the material having low-temperature resistance characteristics such as stainless steel, for example, immersed in liquid nitrogen 3 of -195.8 deg.C and cooled down to the brittle temperature or less of organic substances being contained therein. Next, a vessel 4 made of metal such as a drum can is filled with the solid waste 1 together with the vessel 2 and compressed to several fractions of volume together with the vessel 4 by a compression molding machine 5. Since the organic substances such as rubber and the like contained in the solid waste 1 are cooled and broken like glass, restoring reaction is not produced even if they are restored at ordinary temperature thereafter. Therefore, the thickness of solidification can be thinned without dispersing final waste by inside stress even if a drum can and the like are corroded after burial treatment.

Abstract: PROBLEM TO BE SOLVED: To facilitate the operation when the direction of irradiating laser beam is adjusted or altered by turning the luminous flux through a rotary section and inclining the rotary section through a leveling means thereby forming a reference irradiation spot on a horizontal or vertical reference plane. SOLUTION: A leveling base 10 comprises a base inclinable in two directions provided with adjusting knobs 15, 16 arranged while intersecting the axes perpendicularly. Circular bubble tubes 6, 7, are aligned by turning the knobs thus adjusting the attitude of a laser level roughly. Rotational operation plane of laser light is then corrected horizontally or vertically through an inclination correcting mechanism. A slit plate 90 is provided with a slit 91 directly under the axis of rotary section 2 in order to form a spot light directly under the axis of rotary section 2. According to the arrangement, operability is enhanced when the direction of irradiating laser beam is adjusted or altered because the adjusting direction is aligned with the working direction.
