Patent JP-H10175070-A (JP)
Title: Power unit for arc working
Inventor: TERAYAMA KIKUO
IPC: B23K9/073
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To realize a stable action not causing a jump in output even near zero output, also to reduce the size and cost of a device. SOLUTION: Adjustment of output, that is, ON-OFF control of a switching element bridge connected is conducted by a phase difference based on an output setting. By a constitution with a reference signal generator 21 as a ceter, a voltage control oscillator 25, a phase comparator 22 and a low pass filter 23, signals of a same frequency, in which a phase is shifted by a quantity corresponding to a difference signal ΔS, are given to element drive signals P1, P2 and P3, P4. ΔS is a difference between a signal Sr of an output setter 18 and a signal Sf of an output detector 16. Because action is not affected by energizing/cutoff time lag of a switching element, the output is continuously changed in 0-100% even when a large capacity and slow element is used.

Title: Separately excited flyback converter
Inventor: SUZUKI HIROYUKI
IPC: H02M3/28
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To provide a flyback converter, which is so structured that a main switching element turns on at the lowest point of a resonance voltage waveform to lower a switching loss. SOLUTION: This converter is composed of a series circuit of a main transformer T and a main switching element Q1 and has such a structure that the main switching element Q1 turns on at the lower point of a resonance voltage waveform which is formed by an exciting inductance of the main transformer T and a parasitic capacitor C3 connected in parallel with the main switching element Q1. As a method for realizing this, a time constant determined by a resistor R1 and a second capacitor C2 is changed by making a fine adjustment to the resistor R1, serially connected to a separately excited controlling circuit and a switching frequency is adjusted so that the main switching element Q1 turns on at the bottom of the resonance voltage. For example, the resistor R1 is composed of a series circuit of a fixed resistor and a trimmer resistor, and the trimmer resistor is trimmed to make a fine adjustment to the resistor R1, so that the main switching element Q1 turns on at the bottom of the resonance voltage.

Abstract: PROBLEM TO BE SOLVED: To speedily and certainly detect damage of a bellows for a bellows pump. SOLUTION: A control part CTL closes a solenoid valve SV2, and acquires detected value P1a of a pressure sensor P1. Next, the control part CTL switches a solenoid valve SVA (right position), supplies air to a cylinder 61 forming an air chamber around an extended bellows 63, and acquires detected value P1b of the pressure sensor at this time. In addition, the control part CTL opens the solenoid valve SV2 to extend a bellows 64, then closes the solenoid valve SV1 to keep the extension state of the bellows 64, and switches the solenoid valve SVA (left position). At this state, the control part CTL acquires detected value P1c of the pressure sensor P1. When pressure differences |P1a-P1b|, |P1a-P1c|are derived and if either of them is more than set pressure difference, damage is judged to occur at one of the bellows 63, 64.

Filed: 1991-12-20
Abstract: PURPOSE:To effectively and constantly prevent generation of blurred photographs irrespective of the size of the focal distance and the distance between the subject and a camera even when jiggling having a component in the rotational direction is caused in the camera during photographing. CONSTITUTION:Jiggling which is caused by pressing a release switch 21 in photographing is detected at the specified time interval by means of the first and the second jiggling detecting parts 6A, 6B consisting of an accelometer, and converted into the angular velocity data omegak at the specified time interval by a calculating means 10.

Title: Signal processing method in digital filter
Inventor: ONISHI YOSHIRO
IPC: H03H17/00
Filed: 1996-12-21
Abstract: PROBLEM TO BE SOLVED: To accurately recognize the height of step input signals by performing a signal processing so as not to use data in the middle of the rise of the step input signals as the data. SOLUTION: In the case that the step input signals are converged by one sampling cycle, at the time of defining (n)-th output as Yn , the tap number of a filter as T and (n)-th input as Xn , the signal processing in a digital filter is performed by using an equation I. In the case that the step input signals are not converged by one sampling cycle, without using the M pieces of the data for calculation, the signal processing in the digital filter is performed by using the equation II. Thus, since the dispersion of an output value by the timing of sampling is eliminated, a true value is obtained, the height of the step input signals whose rise is dull is accurately recognized and the peak value of digital filter output is accurately obtained.

Abstract: PURPOSE:To shorten exhausting hours by introducing dry inert gas into a vacuum chamber after exhausting the inside of a vacuum chamber so that the pressure may become the fixed immediate pressure from the atmospheric pressure, and then by restarting exhaust, when the vacuum chamber is exhaust so as be in the vacuum state. CONSTITUTION:When a vacuum chamber 1 made of aluminum, where an object to be vacuum-processed is put in/pulled out is exhausted up to its vacuum state, the inside of the vacuum chamber 1 is exhausted by driving an exhaust system 5 composed of a turbo molecule pump 3 and a hydraulic rotational pump 4 after releasing the vacuum chamber 1 to the atmosphere. And the connection to the exhaust system 5 is shutted off by closing a gate valve 2 when the internal pressure in the vacuum chamber 1 is decreased to about 1X10<-1> Torr. Then the valve 6 is opened to introduce dry nitrogen gas into the vacuum chamber 1 as an inert gas until the pressure may become about the atmospheric pressure. After that, the gate valve 2 is opened as well as the valve 6 is closed, so as to perform exhaust by driving the exhaust system 5 again, thereby a vacuum pressure having, for example, about 8X10<-8> Torr can be obtained.
