Title: Switching power source
Inventor: SATO YUKINORI
IPC: H02M7/06
Filed: 1990-08-24
Abstract: PURPOSE:To control the value of the charge current, the so-called rush current to a capacitor for smoothing cheaply by turning off a thyristor at the point of time when the voltage value that AC input voltage is rectified is higher, and turning on the thyristor only at the point of time when the voltage is lower than it. CONSTITUTION:At the point of time when the voltage value where the timing for turning on a switch is rectified is low, since a Zener diode 11 and a transistor 10 are off, a thyristor 6 is turned on by the trigger current from a resistor 8, and a charge current flows to a capacitor 5 for smoothing. At this time, charge begins at the point of time when voltage value is low, so the peak value of the regular charge current does not become large. Moreover, at the point of time when the voltage value where the timing for turning on the switch 1 is rectified, the Zener diode 11 and the transistor 10 are turned off and the thyristor 6 is turned on when the voltage value has shifted from high point to low point, and a charge current begins to flow to the capacitor 5 for smoothing. Accordingly, the peak value of the charge current does not become large.

Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To perform observation of a sample to be easily damaged caused by an electron beam without drift by synchronizing the period of scanning of electron beams on the sample with the period of scanning of image reading electron beams of an electric image pick-up means. SOLUTION: An electron beam 109 generated from an electron gun 101 is bent by an deflection coil 103 and radiated to the specified position of a sample 104, and an image is formed on an scintillator 106. The image of the electron beam 109 is converted into the image of light 110 by the scintillator 106, so as to be projected on an image pick-up surface 112 by an optical system 111. An image pick-up tube 107 accumulates the image of the light 110 reflected on the image pick-up surface 112 in form of an electric load, reads the electric load by a beam 114, and converts it into an electric signal. Scanning of the beam 114 is performed by a deflection coil 113.

Filed: 1991-09-03
Abstract: PURPOSE: To provide a method to easily form a drill hole a central position of which is precisely set by a core drill regardless of its diameter and material by using a portable drill device. CONSTITUTION: A drill hole is formed while guiding a drilling tool 4 by a guide member by fixing the guide member formed as a disc 1 on a surface of a structural member 3 at the time of forming the drill hole on the structural member 3 by using the hollow cylindrical drilling tool 4. The guide member is, for example, fixed on the surface of the structural member 3 by adhesion or by a fastener element 2 driven on the structural member. Positional slippage of the drilling tool 4 is prevented by making the guide member engaged with an inner periphery of the drilling tool at the time of driving the drilling tool 4. A small diametrical drilling tool is guided by an outer periphery of a head part of the fastener element 2 driven on the structural member 3 or by an inner periphery of a template, for example.

Filed: 1995-08-31
Abstract: PROBLEM TO BE SOLVED: To decrease the circuit scale by equipping the circuit with a gate which only determines output bits from input bird by inverting the LSB and obtaining the LSB of the output data, and then calculating whether or not each bit of the result has a carry. SOLUTION: An AND circuit 21 outputs a signal 201 generated by ANDing low-order bits 102 and 101 of input data. A logical NOT circuit 1 inverts and outputs the input bit 101 of the input data as the lowest-order bit LSB and then outputs the lowest-order bit of the result obtained by adding '1' to the (n)-bit input data, i.e., the lowest-order bit 301 of the output data. An exclusive OR circuit 31 exclusively ORs the input bit 102 and the signal 101 as a signal showing whether or not there is a carry from one low-order bit and outputs the output bit 302 of the output data. Similarly, exclusive OR circuits 32-35 outputs output bits 303-306 on which whether or not there is a carry is reflected, respectively.
