Filed: 1995-07-21
Abstract: PROBLEM TO BE SOLVED: To provide an automatic focusing device and method for an image pickup device capable of attaining a quick and smooth automatic in focus operation and reducible in size and cost. SOLUTION: An image projected by an optical system consisting of a photographic lens 1 and a reflector 10 whose front surface forms a half mirror and rear surface forms a total reflecting mirror is converted into a video signal by an image pickup element 2 and high-frequency components are taken out of the video signal by a first filter means consisting of a filter 11 and a BPF 13 and a second filter means consisting of a filter 12 and a BPF 14, respectively. The high-frequency components are expressed in absolute values by the use of detection circuits 15 and 16 and are compared by a microcomputer 7, to decide a focusing state. A motor 9 is driven according to the results of the decision, to drive the photographic lens 1 in the in focus direction.  The first and second filter means have the characteristics of reversing relative magnitude relations between the respective outputs in the vicinity of the in focal point.

Title: Switching power device
Inventor: ONODERA TOSHIHIRO
IPC: H02M3/28
Filed: 1980-12-26
Abstract: PURPOSE:To perform stable DC voltage conversion without any reaction of a switch by driving a switching element by the output of a blocking oscillating circuit whose pulse width and pulse halt period are settable independently. CONSTITUTION:The conduction period of a switching transistor TR4 is determined nearly by the inductance of the primary winding 13a of a blocking oscillating circuit 3, the current amplification factor of the TR14, and the value of a resistance 17 for pulse control. The off period of the TR4 is determined nearly by a time constant determined by a resistance 15 and a capacitor 16, and the value of a resistance for break-period control. Therefore, only the pulse width of the circuit is varied by the set value of the resistance 17 without changing the basic operation conditions of the circuit 3, and any evil influence is exerted upon the process of determining a break period. Further, the break period is settable independently by the set value of the resistance 20 without exerting any influence upon the setting conditions of the pulse width. Then, output control is exerted easily by making the impedance of the resistances 17 and 20 variable and by controlling it.

Abstract: PURPOSE:To reduce the size of an oscillation sensor by integrating the bending oscillator of an oscillation detector and an electric circuit for processing signals in one laminated piezoelectric element. CONSTITUTION:Disk-shaped piezoelectric elements 1a and 1b having polarizing axes in the direction of thickness constitute a laminated piezoelectric element 1, which is formed with slits 2 and a portion surrounded by the slits 2 forms a bending oscillation mode oscillator 3.

A fixing member 5 with a groove 6 formed in an area against which the oscillator 3 abuts is fixedly mounted to the element 1 by adhesion or the like so that the member 5 is conducted with the lower surface electrode of the oscillator 3 and the surroundings of the oscillator 3 are fixed. Further, an electrode 4 capable of constituting an electric circuit is provided on the upper surface of the element 1 except the oscillator 3 and the upper surface electrode of the oscillator 3 and the input electrode of the electric circuit are common, constituting a signal-processing circuit for impedance transformation and the like, said signal-processing circuit having the member 5 earthed to the electric circuit. Thus, the size of an oscillation sensor can be miniaturized.

Abstract: PURPOSE:To reduce the possibility of exhaustion of hot water without impairing the comfortableness of space heating by providing electric heaters in a hot water storage tank as a means of auxiliary heating at the time of detected hot water-temperatures falling below standards and by providing also a means of stirring the hot water in the hot water storage tank. CONSTITUTION:In a hot water storage tank 31, a heat exchanger 25 for hot water supply is fixed to the cylindrical side wall and electric heaters 39 are attached between heat exchanger coils. At the height of the top end of the heat exchanger 35 for hot water supply is attached a first hot water-temperature sensor 41 and above it are attached a second, a third, and a fourth hot water-temperature sensors 42, 43, 44. The operation is controlled in such a manner as to bring the room temperature and the temperature of the hot water in the hot water storage tank 31, which are detected during the operation, close to their respective prescribed temperatures. When the temperature of the water heated in the hot water storage tank 31 is low, the electric heaters 39 perform auxiliary heating without leaving the temperature low so that the possibility of exhaustion of hot water when the outdoor temperature is low is reduced. The temperature of the water heated is also raised by stirring in the hot water storage tank 31 before exhaustion of hot water so that switching to the simultaneous operation takes place automatically.

Filed: 1998-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a software decision decoder provided with the convolution code of a large restriction length, a low current for the communication channel of low BER and an MIPS (millions of instructions /second) processing request. SOLUTION: A hardware decision detector 210 for each symbol decides a hardware decision vector from a demodulation reception signal vector. The hardware decision vector is multiplied by a scalar parity check matrix and a syndrome vector is calculated. A syndrome change device 230 checks the syndrome vector to a prescribed syndrome pattern corresponding to a separated error in the hardware decision vector. The syndrome pattern is removed from the syndrome vector, the changed syndrome vector is generated and the corresponding error in the hardware decision vector is recorded in an estimated error vector. By using the changed syndrome vector, a simplified error trellis is prepared so as to generate remaining error vectors.

Title: Method for bonding synthetic resin sheet
Inventor: YAMAUCHI MASAHARU
IPC: B29L7/00
Filed: 1987-07-27
Abstract: PURPOSE:To make it possible to easily butt-weld synthetic resin sheets, on which even fine ruggedness or lenticular surface is made, by a method wherein highly viscous, easily peelable and flexible starching material is applied on both sides along the direction of the length of a butt-welding point so as to pour liquid adhesive in the point for bonding and, after the pouring, the starching material is removed. CONSTITUTION:On the surfaces of synthetic resin sheets 1 and 1 to be bonded together, for example, lenticular lenses 1A are formed. When the synthetic resin sheets 1 and 1 are acrylic resin sheets, dichloromethylene is used as the adhesive. Highly viscous starching material 3, which can be easily removed later and flexible, is applied on both sides along the direction of the length of a butt-welding point and, after the application, liquid adhesive 4 is poured in the point. At this time, the surplus of the poured liquid adhesive 4, which tends to flow laterally due to the lenticular lenses 1A provided on the surfaces of the synthetic resin sheets 1 and 1, is prevented from flowing by the starching material, which is applied so as to fill the groove parts of the lenses. As the preferable starching material 3, for example, water solution of polyvinyl alcohol or of cellulose is used.

Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To automatically return to linkage operation by determining a period of system voltage through a first timer means, a second timer means, and a central processing unit, and then operating a parallel-off relay. SOLUTION: In confirmation of system restoration after a service interruption, a central processing unit 114, after a first counter 109 has counted by a prescribed number of times, issues a command to a measurement interval judging means 110 to disregard the periods out of ranges as being deemed 50 or 60 Hz and causes a first timer means 108 to make remeasurement without varying the starting point of measurement.  A second counter 111 counts the number of times of period measurement, which has managed to pass the measurement interval deciding means 110, and when a prescribed value is reached, it instructs the central processing unit 114 to make system decision, If either frequency has been counted four or more of five times, the ventral processing unit 114 decides that as system restoration and instructs a parallel-off relay drive unit 116 to operate a parallel-off relay 115, thereby starts system linkage operation. Thus automatic return to linkage operation is performed.
