IPC: H03K5/08
Filed: 1989-03-18
Abstract: PURPOSE:To obtain a stable output by providing a power supply voltage compensation circuit controlling a constant current circuit so as to cause a constant current to flow even when a power supply voltage is fluctuated. CONSTITUTION:A series circuit comprising a transistor(TR) Q1, a diode D1, a resistor RD1, a resistor RD2 and a diode D2 connects between a 1st power supply GND and a 2nd power supply VBB. An upper terminal of a resistor RB1 connects to the 1st power supply GND and the lower terminal connects to a base of the TR Q1 and the upper terminal of a constant current circuit and the lower terminal of the constant current circuit connects to a 3rd power supply VCC. Then a power supply voltage compensation circuit controls the constant current circuit so as to cause the constant current circuit to flow a constant current even when the voltage of the 3rd power supply VCC is fluctuated. Thus, the level of the output is made constant independently of the fluctuation of the power supply voltage VCC even when a low level signal is supplied to an input terminal VIN and the stable output with small overshoot or undershoot is obtained.

Title: Air passage switching device and air conditioner for vehicle
Inventor: OFUJI NOBORU
IPC: B60H1/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To rapidly switch a face mode to a defroster mode in a vehicle air conditioner having a filmlike member whose movement switches a plurality of air passages of blowoff opening parts, by providing both a motor for moving the filmlike member to one direction with torque and a coil spring for moving the filmlike member to the other direction with spring force. SOLUTION: In this vehicle air conditioner, a spring force of a spring 29 moves a filmlike member 20 to switch a force mode to a defroster mode. When the spring force moves the filmlike member 20, a motor 23 requires only a low torque to rotate at a high speed so that a mode switching time is reduced. As a result, the switching to the defroster mode is rapidly performed so that cloudiness on window glass is rapidly eliminated.

Abstract: PURPOSE:To prevent generation of cavitation in a motor by a method wherein a part of handling liquid, pressurized by an impeller, is pressurized by a rear vane to a pressure higher than the discharging pressure of the pump and is introduced into a canned motor from the scroll chamber of the pump through a path therefor. CONSTITUTION:A part of the handling liquid 48, pressurized by the impeller 35, is pressurized by the rear vane 42 to a pressure higher than the discharging pressure of the pump and is introduced into the canned motor 21 from the scroll chamber 43a of the pump through the paths 44, 45 as shown by arrow signs in the diagram. Thus, the handling liquid 48 in the canned motor 21 is being pressurized, however, the pressure thereof is showing a pressure between the discharging pressure of the rear vane 42 and the same of the pump and, therefore, it becomes higher than the discharging pressure of the pump. Accordingly, there is no fear to generate the cavitation in the canned motor 21 and, therefore, lubrication of the bearings 32, 33 as well as the cooling of the canned motor 21 may be effected surely.

Title: Method for reducing undesired electric field
Inventor: HAYASHI SHIGEO
IPC: H04N3/185
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce an undesired electric field emitted from a tube screen of a cathode ray tube display device by applying a pulse voltage whose polarity is opposite to that of a pulse voltage generated from a deflection yoke to an outer conductive film. SOLUTION: When a pulse voltage is generated from a deflection yoke 5, the pulse voltage is electrostatically induced on an inner conductive film 2 and an undesired electric field is emitted from a tube screen of a cathode ray tube 6. When a negative pulse voltage whose polarity is opposite to the pulse voltage and obtained from a secondary winding m2 of a cancel transformer T1 is applied to an outer conductive film 1, since a capacitor C2 and a breeder resistor R1 form a differentiation circuit, the pulse voltage is induced electrostatically on the inner conductive film 2. Then the magnitude of the undesired electric field emitted from the tube screen of the cathode ray tube 6 is adjusted by adjusting the pulse voltage with a variable resistor VR1. As a result, the undesired electric field emitted from the tube screen of the cathode ray tube 6 is reduced.

Abstract: PURPOSE:To execute a high speed arithmetic processing by switching part of an input and an output of the memory of a signal processing system for executing plural times such a process as an output obtained in a processing process of the previous stage is processed in the next stage to omit a transfer processing. CONSTITUTION:In a memory 12, data to be processed is stored, and a selector 16 and a selector 17 are set to A and B, respectively as initialization. The data to be processed passing through the selector 16 from the memory 12 is inputted to a computing element 19 and an arithmetic operation is executed, and after the operation is finished, operation result data passes through the selector 17 and is stored in a memory 13, and in this case, a controller 15 which receives a control signal 14 outputs a system 18 and the selectors 16, 17 are switched to B and A, respectively. When the processing goes into the next arithmetic process, the previous result data passes through the selector 16 from the memory 13 and is inputted to the computing element 19 and the processing is executed. In such a way, whenever the arithmetic operation is finished, the selectors 16, 17 execute switching of A and B, therefore, a high speed arithmetic processing can be executed.

That is, the temperature dependency of the resist film thickness is interpreted quantitatively and resist-applying conditions capable of controlling the influence of temperature to a minimum are set on the basis of the results of such interpretation. Thus, a resist application can be conducted with a uniform film thickness.

Filed: 1993-03-02
Abstract: PURPOSE:To obtain an excellent compression ratio for the pattern having the same period as that of a dither matrix, in an image information processor performing a dither processing for a multi-level image and binarizing it. CONSTITUTION:A binarization part 3 converts a 16-gradation digital image signal DS16 into a 4-bit binary image signal DSs by comparing the signal DS16 with the threshold of the first line of a dither matrix 5. A picture element order conversion part 6 rearranges each picture element of the binary picture element signal DSs in order of the small thresholds of the dither matrix 5 and outputs a binary image signal TS2. A run length count part 8 generates the classification of the continuous binary picture element signal TS2 by the same pattern and the continuous binary picture element signal TS2 by different patterns and run length i-information showing the number. A run length addition part 7 adds the run length information before the binary picture element signal TS2, eliminates the remaining binary picture element signal TS2 of the same pattern by leaving one of the signal and outputs a run length addition signal RS2.

Title: Method and device for manufacturing pipe with rib
Inventor: IIRI IEERUBUENKIREE
IPC: B29C48/13
Filed: 1987-03-20
Abstract: This invention relates to a method and an apparatus for the production of ribbed pipes. The apparatus comprises a core (8, 9, 10) which together with an extrusion sleeve (4) forms a nozzle (11) through which a plastic material is fed into a moulding space (12) defined between a mandrel (9) and chill moulds (1, 2) moveable with respect to the mandrel. Ribbed pipes produced by means of known apparatuses have, for various reasons, an uneven inner face, incomplete ribs or air closures and weak seams in the pipe walls and ribs. These disadvantages can be eliminated by such a dimensioning of the moulding space (12) of the apparatus and the grooves (13) of the chill moulds that the volume of a space defined between a plane (20) extending adjacent to the end face of the extrusion sleeve, a surface (16) of the mandrel, and a plane (17) comprising the envelope surface of the kernel (10) equals to the combined volume of the grooves (13) positioned within the area of the mandrel at each particular moment.
