Patent JP-S62241742-A (JP)
Title: Dc system electric railway
Inventor: NOKI SADAJI
IPC: B60M3/02
Filed: 1986-04-10
Abstract: PURPOSE:To compensate a voltage drop in an electric-car line, by doing chopper control over the output of a second forward power transformer at a chopper circuit according to a load factor of an electric car, and feeding this chopper- controlled output to the electric car after being added to the output of a first forward power transformer. CONSTITUTION:When a thyristor 9 of a chopper circuit 8 is controlled to be turned on, an output current of a diode rectifier 14 flows to the negative pole side of the rectifier 14 through a reactor 10 whereby an output voltage of the rectifier 14 is reduced. Next, when the thyristor 9 is controlled to be turned off, the energy stored so far in the reactor 10 flows through a diode 11, thus the output voltage of the rectifier 14 is impressed on an output voltage ED of a diode rectifier 1. Thus, on-off control over the thyristor 9 is repeated whereby the output voltage mean value ed of the rectifier 14 is controlled. Therefore, if the thyristor 9 is controlled to be turned on or off so as to make this voltage ed larger, a voltage drop in an electric-car line to be connected to a DC bus-line 3 is compensable.

Abstract: PURPOSE:To widen the frequency range of a pulse signal to be detected and to reduce voltage and power consumption, by constituting a charge and discharge circuit for charging a capacity element with power source voltage and opening and closing a switching circuit by the control signal computed from the cycle or width of a pulse to be detected. CONSTITUTION:A differentiation circuit DF 1 differentiates the pulse signal to be detected applied to a terminal CLK and outputs a differential pulse having a width substantially shorter than the cycle of said pulse signal to be detected at the point of time when the level of the pulse signal to be detected changes. A capacity element C1 is connected to a power source VSS at one terminal thereof and a switch circuit SW 2 is connected to the element C1 in parallel. A switch circuit SW 1 has the differential pulse output of the circuit DF 1 as control circuit to connect the parallel circuit of the element C1 and the circuit SW 2 to the power source VDD only for the time corresponding to the width of the differential pulse. The circuit SW 2 is brought to an open state only for the time corresponding to the width of the differential pulse by a control circuit TM 1. The voltage applied to the element C1 is reversed by a reversal device INV 1 to be outputted. By this method, the frequency range of the pulse signal to be detected can be widened, and voltage and power consumption can be reduced.

IPC: G01B11/14
Filed: 1987-04-07
Abstract: PURPOSE:To measure a gap of down of <=0.1mum by using white light by providing a groove whose bottom part slants in parts of the reverse surface of an optical head from its one end to the other end. CONSTITUTION:The groove 11 is formed in the reverse surface 1a of the optical head 1 and the bottom part 11a of the groove 11 slants to a flexible disk 2. When light 3 with single wavelength is projected from the top surface 1b of the head 1, part of it is reflected 3a' by the bottom part 11a and light transmitted through the head 1 is reflected 3b by the surface of the disk 2. Here, when the wavelength of the light 3 in use is denoted as lambda, interference fringes are formed on condition that the interval between the bottom part 11a and the surface of the disk 2 is >=lambda/4. Therefore, even when the gap between the reverse surface 1a of the head 1, e.g. slide surfaces 10a and 10b and the surface of the disk 2 is <=lambda/4, it is measured sufficiently and the fine gap of <=0.1mum can be measured.

Abstract: PROBLEM TO BE SOLVED: To form a uniform and sufficient molten molding powder layer and to suppress the longitudinal surface crack of a slab by subjecting the region of the molding powder layer near an immersion nozzle in a casting mold for continuous casting to dielectric heating with microwaves. SOLUTION: The molding powder region (the region enclosed by a, b, c, d in Fig.) near the immersion nozzle 4 enclosed by the long size part of the casting mold at a distance half the calculated width wf of the thin molten layer of the molding powder on both sides from the central part of the casting mold is subjected to dielectric heating, by which the sufficient thickness of the molten layer of the molding powder is obtd. The inflow defect of the molten molding powder between the casting mold and a solidified shell is prevented and the local heat extraction defect of the casting mold is eliminated, by which the surface crack of the slab is prevented.  The dielectric heating by the microwaves directly heats the molding powder and, therefore, the molding powder is uniformly heated from the surface layer to the inside thereof and since the heating is executed in the casting mold, such heat extract as in a powder transporting stage does not occur of and the release of the heat into the atmosphere is prevented.
