Title: Method for controlling molten metal level in continuous casting
Inventor: EGASHIRA TAKEJI
IPC: B22D11/18
Filed: 1982-03-17
Abstract: PURPOSE:To stabilize the level of a molten metal in a mold and to produce a continuous casting ingot having high quality in the stage of changing the control for the constant position of the level of the molten steel in the mold of a continuous casting device from manual to automatic control, by starting the automatic control when the difference between the target level and the actually measured level is zero. CONSTITUTION:The molten steel in a tundish 2 is charged into a mold 3 for continuous casting by the operation of a stopper 4. In this case, the level of the molten steel in the mold is detected with a level gage 6, and a driving part 8 for the stopper is driven by a controller 7 to open or close the stopper 4 by as much as the deviation from a target level value, whereby the rate of charging is controlled automatically. When abnormality in casting arises, a manual driving device 9 for the stopper is operated by a man to control the level of the molten metal adequately. During the manual operation, the target level is beforehand so set as to follow up the actually measured level value, and the automatic control is started with the actually measured level value when the cylinder rod of the driving device for the stopper contacts a moving device 4' for the stopper as a target value, whereby the level of the molten steel in the mold 3 is maintained stably at the target value.

Title: Spectroscope using concave surface diffraction grating
Inventor: KOIKE MASAHITO
IPC: G01J3/06
Filed: 1980-03-31
Abstract: PURPOSE:To make it possible to execute the wavelength scanning with higher accuracy, by constituting so that a rotary axis of the diffraction grating can move forward and backward against the line connecting the incident and emitting slits, and making it move finely so as to satisfy the prescribed condition by being interlocked with the wavelength scanning. CONSTITUTION:In a simple rotation concave surface diffraction grating spectroscope, the concave surface diffraction grating 1 is fixed to the pin 9 which has been fitted into the fixed guide 8. When a screw shaft 4 is rotated, a nut which is spirally fitted into the screw shaft 4 is moved, and a bar 6 which is fixed to the nut 7 so as to freely rotate is rotated around a rotary axis 5 of the diffraction grating 1, and simultaneously is moved forward and backward. The diffraction grating 1 is interlocked with rotation by the sine bar mechanism, and finely moves forward and backward around both the ends of the scanning wavelength area, and in the center area, respectively. Accordingly, the wavelength scanning of high accuracy can be executed.

IPC: H01L21/302
Filed: 1988-02-25
Abstract: PURPOSE:To completely flatten the surface of an interlayer film by mechanically polishing the protrusion part of the surface of the film generated by chemically forming a thin film. CONSTITUTION:A gate oxide film 11 is formed on a semiconductor substrate 10, and then patterned to form a polysilicon film 12. Then, an oxide film 13 is formed by a normal pressure CVD 1mum thick as an interlayer film on a whole surface, and allowed through a heat-treating step to reflow. Similarly, a normal pressure CVD oxide film 14 is superposed 2mum thick in this state, and heat-treated. After it is treated through such a step, the interlayer film is deleted approx. 1.5mum by a wafer polishing unit. Since the polishing is of a mechanical polishing method, the film is accurately deleted, thereby obtaining a smooth interlayer film which is not affected by the influence of the step of a polysilicon film at all.

Filed: 1992-02-28
Abstract: PURPOSE:To execute commodity charging work on a lower position and to easily replenish commodities by moving a commodity storing unit to the lower part of an automatic vending machine(AVM) body by a driving mechanism. CONSTITUTION:A driving mechanism 20 for a commodity storing unit 10 corresponding to commodities to be replenished is driven by an operation part and the unit 10 is moved to the lower position of a commodity stock part 4. An inner door 6 is opened, the unit 10 is drawn out to the front part of the AVM body 1 and new commodities A are charged from the aperture part 10a of the unit 10 to complete the replenishment of the commodities A. Since the commodity replenishing position is arranged on the lower part of the body 1, the charging work of the commodities A is executed at the low position. Namely the commodity charging position can be lowered by moving the unit 10 to the low part of the body 1, so that commodity replenishing work can be extremely easily executed. Since the unit 10 is formed as a box shape opened at its upper face, many commodities can be charged at a time.

Title: Instrument for measuring propagating time of ultrasonic wave
Inventor: RIYUUDEIGAA HERUTSUAA
IPC: G01N29/07
Filed: 1990-02-26
Abstract: PURPOSE: To prevent the occurrence of an error caused by the change of the traveling time of ultrasonic waves by adjusting the delay of a time gate by impressing the output signal of an envelope modulator upon a threshold comparator, the output of which is connected to a gate circuit, and a maximum value detector. CONSTITUTION: The ultrasonic echo of a preamplifier 35 is impressed upon an envelope modulator 38 and an envelope signal is impressed upon a comparator 40. The threshold of the comparator 40 is selected so that the amplitude of the threshold can become slightly larger than that of noise. The output of the comparator 40 is supplied to a gate circuit 43 and forms a starting point of time. An MPU 32 controls the delay time of the circuit 43. The envelope signal is also impressed upon a maximum value detector 44 and the output of the detector 44 indicates the point of time at which the ultrasonic echo becomes the maximum. The output signal of the detector 44 is inspected for the temporal coincidence with the output of the gate circuit 43 at an FF circuit 58.  The ultrasonic echo of the amplifier 35 is impressed upon an ECL comparator 49 and the comparator 49 generates an acicular pulse at the zero passing time of the ultrasonic echo. Therefore, a rectangular pulse can be obtained from an AND element 48.

Title: Positioning stopper in conveyor
Inventor: KURITA YUTAKA
IPC: B65G43/00
Filed: 1986-02-28
Abstract: PURPOSE:To aim at making sure of stopping a truck at the specified position even at the time of its inrush speed and weight are large enough, by adding such a voltage (current) as proportionate to the absolute value of displacement to a stopping position of the detected conveying truck, to the specified voltage (current) in total, and feeding the primary side of an electromagnet with the totaled one. CONSTITUTION:When a conveying truck 1 reaches to the vicinity of a stopping position, exciting voltage corresponding to voltage V0+K1¦X¦ adding up the voltage K1¦X¦, proportioned to the absolute value ¦X¦ of displacement X, to the specified voltage V0 is fed to a coil 5, so that restoring force (f)=-K0(V0+K1¦X¦)X corresponding to this voltage V0+K1¦X¦ acts on the truck 1. That is to say, the exciting voltage to be fed to an electromagnet 6 grows large in proportion as the truck 1 gets away from the stopping position 2, whereby force for pulling the truck back strongly acts on it. Therefore, even at a position away from the stopping position 2, sufficiently large restoring force (f) acts on the truck 1, and thereby even in case inrush speed and weight of the truck 1 are large enough, the truck 1 is surely stoppable at the stopping position 2, therefore such a fear that the truck 1 might deviate from an operating range of a positioning stopper is preventable.
