Patent JP-S6232268-A (JP)
Title: Vacuum regulator
Inventor: SAKAI SUMIO
IPC: F02M25/06
Filed: 1985-08-01
Abstract: PURPOSE:To easily obtain a desired vacuum in a vacuum chamber communicated with a vacuum induction nozzle and an output nozzle and also communicated with an atmospheric air intake hole adapted to be opened and closed by an armature, by regulating a proportion of opening or closing time according to contact or separation of the armature with respect to a seat. CONSTITUTION:When a coil 16 is not supplied with current, and a vacuum induction nozzle 36 and an output nozzle 38 are open to the atmosphere to generate small pressure differential across an armature 44, the armature 44 is kept in tight contact with a seat 46 by a biasing force of a spring 45. When the coil 16 is not supplied with current, and a degree of vacuum in a vacuum chamber 32 is increased to generate a pressure differential between the atmospheric pressure across the armature 44 and the vacuum in the vacuum chamber 32, the armature 44 is moved away from an end surface of the seat 46 to thereby permit the atmospheric air to flow from an atmospheric air intake hole 13 through a gap between the armature 44 and the seat 46 into the vacuum chamber 32. When the coil 16 is supplied with current, and a fixed iron core 11 is excited to attract the armature 44 onto the end surface of the seat 46, thereby blocking the flow of the atmospheric air into the vacuum chamber 32.

Title: Method for controlling generated code quantity
Inventor: ARIMA MASAKI
IPC: H04N19/152
Filed: 1990-06-28
Abstract: PURPOSE:To control a generated code quantity by providing a moving vector detection circuit whose moving vector detection range is able to be controlled externally and varying the moving vector detection range in response to the residual quantity of a transmission buffer so as to reduce the production of an invalid time to the utmost. CONSTITUTION:A frame emission circuit 15 receiving picture elements from a camera 14 decreases the number of frames indicated to a variable length coding circuit 18. Suppose that an N-th picture frame is inputted to a moving vector detection circuit 16, then the circuit 16 compares total picture elements in a detection range 13 with picture elements at a picture element position 12 to retrieve a picture element in which the error is minimized. A quantization circuit 17 quantizes a prediction error E. A variable length coding circuit 18 codes the quantized value into a variable length code and outputs the result to a transmission buffer 19. An inverse quantization circuit 20 restores the quantized value into the original prediction error E. When the buffer storage quantity in the transmission buffer 19 is not reduced below the threshold value, the variable length coding circuit 18 controls the frame omission circuit 15 to decrease the number of frames till the buffer storage quantity reaches the threshold value or below. Since the frame omission control is implemented as a final means, the ineffective processing time is reduced.

Title: Converter refining method
Inventor: SUZUKI HISATADA
IPC: C21C5/34
Filed: 1983-09-16
Abstract: PURPOSE:To suppress preferential oxidation of Si and to extend the life of a tuyere for which a double-layered pipe is used by operating a converter at the prescribed rate of dilution by an inert gas of O2 passing through the inside pipe of the tuyere which is increased to the rate higher than in a stationary state while Si exists at industrial purity in the bath. CONSTITUTION:The impurities in molten iron are usually oxidized in order of Si and C when the molten iron is oxidation-refined. Si is particularly preferentially oxidized and the oxidation of C is suppressed during this time in the initial period of refining particularly with such a converter as a top and bottom blown converter and a bottom blown converter having large stirring power. The rate of dilution of O2 to be blown through the inside pipe of a double-layered pipe tuyere is increased to the rate higher than in an ordinary condition and the converter is operated at 40-70% rate of dilution in the so-called desiliconization period in the above-mentioned period when a large quantity of heat is generated. As a result, the generation of heat by combustion of Si in the desiliconization period and the corrosion of the slag coating layer by SiO2 are decreased and the rate of eroding the tuyere is retarded.

Title: Dual-band transmitting and receiving circuit
Inventor: ISHII KATSUHIRO
IPC: H04W88/06
Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To enable a single transmitting and receiving circuit to perform transmission and reception at the same time even when system of the transmission band and reception band are different and the frequencies are greatly different by using a desired wave and higher harmonies, generated at frequencies as integral multiples of the frequency, which are outputted by an oscillator at the same time instead of local oscillations of the transmitting and receiving circuit. SOLUTION: A signal inputted as a modulated signal input and a signal outputted from a low-frequency local oscillator 37 for transmission are mixed by a modulator 34 and outputted to an up converter 33. The up converter 33 mixes the signal outputted from the modulator 34 and the signal outputted from the high-frequency local oscillator 35 and outputs the sum or difference frequency to a transmitting RF band-pass filter 40. The transmitting RF band- pass filter 40 attenuates frequency components other than a desired transmission band and outputs the signal. Consequently, transmitting and receiving operations can be performed at the same time in two frequency bands which are greatly different.

IPC: F16H55/18
Filed: 1994-06-30
Abstract: PURPOSE:To provide a backlash-free gear at reduced cost by forming the teeth of at least one of meshing gears from an elastic material, and forming slits from approximately the center top to the center of each tooth. CONSTITUTION:A gear 1 is formed from an elastic metal or a resin, etc., and a slit 4 is formed from approximately the center top to the center of each tooth 3 formed on the edge of the gear 1. In order to prevent the strength of the teeth 3 from being decreased by the formation of the slits 4, the side 3a of each tooth 3 is curved to increase thickness as necessary. Such slits 4, when the gear is metallic and relatively large, are cut by wire, or saw-tooth, machining, while when the gear is small they are formed by discharge machining and the like. Therefore, when two gears mesh and rotate, the slits 4 cause elastic deformation of at least one of the gears, thus preventing a backlash.
