Filed: 1990-05-16
Abstract: PURPOSE:To manage a residual amount and sale by measurement with a single pressure sensor so as to have regular consumers by calculating a consumption amount of kerosine by an electric signal which varies according to a liquid level change inside a herosine tank and transmitting the signal to a kerosine supplier. CONSTITUTION:A pressure sensor 11 mounted on a drain hole 10 at the bottom of a kerosine tank 1 is used to detect a liquid level of kerosine and inputs the value as an electric signal to a converter 12 which is a counting means provided indoor. The converter 12 amplifies the input electric signal of the kerosine level, converts it into a signal corresponding to a capacity unit and outputs it as a kerosine amount signal to a transmission controller 13 placed indoor. The signal is transmitted by the controller 13 via a telephone line to a host computer 14 placed on site of a kerosine supplier with appropriate intervals. Thus the kerosine supplier can constantly monitor the residual amount of kerosine of each consumer through the computer 14 while a consumption amount can be measured from a difference in residual kerosine amounts within a predetermined period, which is to be a calculation reference in planned sales.

Abstract: PURPOSE:To automatically fast forward a tape only in its defective reproducing part by storing an absolute time from an error starting point to an error ending point in the defective reproducing part at the time of reproducing for the 1st time and fast forwarding the tape from the error starting point of the defective reproducing part to a prescribed position at the time of reproducing after the 1st time. CONSTITUTION:When the tape is commenced to be reproduced, it is monitored by a system controller (microcomputer) 5 based on an error rate of a reproduced signal being sent from a signal processing circuit 3 as to whether the present tape position under reproduction is the defective reproduction part or not. Then, when the error rate exceeds a prescribed value, this position is detected as the defective reproduction part, and the absolute time of the error starting point and the error ending point in this defective reproduction part is read out respectively and these are stored. Then, the tape is reproduced again, and when the tape position comes to the stored error starting point of the defective reproducing part, the tape is changed for a high speed search mode, and is fast forwarded from the error starting point to the prescribed position. By this method, the tape can automatically be fast forwarded through its defective reproducing part at the time of reproducing after the 1st time.

Title: Method for driving thin film el light emission
Inventor: SATO YOSHIHIDE
IPC: H05B44/00
Filed: 1991-04-30
Abstract: PURPOSE:To evade excessive stress upon an EL element switching element due to the asynchronism between the driving voltage of an EL element and the EL element switching element and to prevent a light emission device from deteriorating by properly synchronizing a signal which determines whether the EL element emits light or not and the EL element driving voltage. CONSTITUTION:Each EL element is applied with the driving voltage, but when the EL element is OFF, its drain voltage is set below the ON-time rated maximum voltage. For the purpose, when a data signal is written in the EL element, the driving voltage Va is set to 0V. A common power source is used to drive the EL element, so when the device is controlled with a serial data signal, the driving voltage Va is applied for the period Tm from the end of the period of writing to one block to the start of writing to a next block, so that only the EL element set in an ON state illuminates. The driving voltage Va is reset to 0V again after the period Tm and the writing to a 2nd block and the application of the driving voltage are repeated.

Title: Laser processing method and processing machine
Inventor: MATSUMOTO YUJI
IPC: B23K26/00
Filed: 1998-05-07
Abstract: PROBLEM TO BE SOLVED: To carry out high precision shape processing to a material surface by ejecting a laser beam to a surface of liquid with an inclination, adjusting the height of the liquid surface, moving the laser beam along the material surface, and controlling a rotational radius of the laser beam. SOLUTION: A laser beam 8 is incident on an oil at an angle A, and is condensed on a processing face 6 inclined by an angle B from a vertical direction 7 by means of a convex lens 1. When the height of the liquid surface is set to be D, an irradiation shaft of the laser beam to the processing face 6 is a rotational center shaft 9 of a workpiece. When the height of the liquid surface is changed to be d, a rotational radius r is also changed from n=sin(A)/ sin(B) to r=(dtan(A)-dtan(B)×cosA. In the formula, n shows the refractive index of the liquid, A shows an incident angle, and B shows a refractive angle. Since rotation of the beam is carried out by the control of the liquid surface height, a wedge plate having a high precision peak angle is not required.  Each of optical axes 9, 10 of the refractive lights at the time of changing the liquid surface is parallel by using the refraction of the liquid surface.

Title: Method for dissolving hardly soluble powder
Inventor: YAMAMOTO YOSHITAKA
IPC: C25D21/14
Filed: 1983-07-11
Abstract: PURPOSE:To dissolve a substance to be dissolved remaining to a filter, in a method wherein a suspension having a hardly soluble substance to be dissolved suspended therein is supplied to a tank through the filter to use the solution of the tank, by recirculating a part of the solution to the filter. CONSTITUTION:A hardly soluble substance to be dissolved (e.g., NiCO3) is suspended in a mixing tank 10 and the resulting suspension is supplied to a tank 12 through a filter 11 while the filtered suspension stored in the tank 12 is sent to an electrolytic cell 13 by a pump 14 to perform plating. A part of said plating liquid is again supplied to the filter 11 by an arranged pipe 20 and the undissolved hardly soluble substance to be dissolved remaining to the filter 11 is dissolved to be introduced into the tank 12. That is, because the undissolved hardly soluble substance to be dissolved can be perfectly dissolved by supplying a part of the plating liquid to the filter from the tank while holding the plating liquid to a normal composition, this inventive industrial effect is large.
