Title: Invertor type x-ray apparatus
Inventor: HINO HIROBUMI
IPC: H05G1/20
Filed: 1984-01-14
Abstract: PURPOSE:To obtain stable bulb voltage waveforms by preventing an overshoot or depression of bulb voltage waveform generated at the time of starting irradiation of X-ray. CONSTITUTION:Charges of a smoothing capacitor 4 start to be discharged through a dummy load resistor 21 and a transistor switch 22 and thereby a voltage drops. Accordingly, a current IL starts to flow into a smoothing reactor 3, due to the difference of voltage between the smoothing capacitor 4 and a power supply 1 and the current IL becomes a normal value at the timing t-1. Thereafter, a D-D converter 5 and an inverter 7 start to operate at the timing t0. Simultaneously, a base current IB of transistor switch 22 stops, turning OFF the transistor switch 22. When viewing from the side of power supply 1, the power is supplied already to the dummy load resistor 21 at the timing t-2 and a large transition phenomenon is not generated even when the power supplied to an X-ray bulb 11 used as an actual load from the dummy load resistor 21 is changed at the timing t0. Therefore, the power can be supplied to the actual load (X-ray bulb 11) while the charging voltage VR of smoothing capacitor 4 and the current IL to be applied to the smoothing reactor 3 are stabilized.

Abstract: PURPOSE:To roll efficiently and continuously a steel strip through one process by heating the strip, rolled into the intermediate sheet-thickness to a specific temperature to maintain the strip at said temperature on the way of rolling, and cooling it to roll under a specific rolling reduction at the next and subsequent stands in continuously cold rolling the strip by multi-high tandem mills. CONSTITUTION:A steel strip 6 is uncoiled from an uncoiler 1, and the tail end of a preceding strip and the front end of a succeeding strip are joined together into a joined strip 6 by a welder 2. A steel strip storing device 3 stores the fixed amount of strip because the rolling is continued even when the welding is operated. The strip 6 delivered from the device 3 is rolled in sequence into the intermediate sheet-thickness by the mills #1-#3. Next, the strip 6 is heated by a heat treatment device 7 and is maintained at the temperature of 200-400 deg.C for a proper time, before it is cooled to the temperature suitable for cold rolling. After finishing the heat treatment, the strip 6 is successively rolled under >=20% rolling reduction by the next stand #4 and subsequent ones into the prescribed thickness and is wound up in sequence by coiler 5.

IPC: G01B11/00
Filed: 1981-01-21
Abstract: PURPOSE:To make physical quantity measurable with high accuracy by utilizing the monochromatic light emission characteristics of laser beam and its oscillation wavelength stability. CONSTITUTION:The forward path of parallel rays 2 passed through a shutter 10 from a half mirror 6 is focused by a lens 32 and is made incident to an optical fiber 33. While the rays 2 maintain a single mode in the fiber 33, they arrive at a sensor 34. The rays 2 arrive at a reflection mirror 35 in the medium of the sensor 34 in the single mode, and they are reflected there and are reflected by the half mirror 6 through the backward path of the rays 2, thereby forming a part of a rays 3. When the velocity of light in the medium of the sensor 34 changes with measuring physical quantity, the phase at which the backward path of the rays 2 is made incident to the half mirror 6 changes. From this change in the position, the measuring physical quantity applied to the sensor 34 is measured.

Abstract: PURPOSE: To simplify the circuit constitution as well as facilitate an easy control by applying the alternating field generated from the coordinates indicator to the lead wire on the tablet to detect the scale of the induced voltage and thus deciding the coordinates position.  
     CONSTITUTION: When coordinates indicator 4 which generates the alternating field is put on tablet 1, the AC signal of frequency f 0  is induced to sense wires Xi and Yj each. This signal is piled on the scanning signal only when the scanning signals of scanner circuits 3X and 3Y are applied, and then led out to output line l through diode D. This signal is then amplifier 9 and then supplied to BPF10 which makes pass frequency f 0  to give discrimination, amplification 11 and smoothing 13 to the induced signal, and formed into the smooth waveform to then undergo amplification 14 and A/D conversion 15. Operation control part 16 gives the high-speed scanning to the sense wire and then leads in the induced voltage from converter 15 in sequence to obtain the coordinates value of the designated point from each voltage value. And the coordinates value, if obtained, is memorized temporarily; while in case the value cannot be obtained, the ineffective process is given. At the same time, the control is given to switch circuit 8, amplifier 9, external unit 22 and others in order  to give compensation to the induction level difference of pens 4bW4c.
