Inventor: MORIBE MINEO
IPC: G11B7/26
Filed: 1986-10-15
Abstract: PURPOSE:To improve a production yield by enabling control of an increase of an error rate even if a transfer mold is used repeatedly, by making use of the transfer mold whose temperature has been risen through irradiation of ultraviolet rays by cooling the transfer mold down to a temperature at a value prior to the irradiation of the ultraviolet rays. CONSTITUTION:Ultraviolet curing resin 3 is piled up on a guide groove 2 of a transfer mold 1 made of nickel. Then, positioning is performed by mounting a transparent base on the same and the transparent base is pressed. Then, the ultraviolet curing resin 3 is cured by irradiating ultraviolet rays to the same. In this instance, the irradiation is performed by restoring the transfer mold 1 to the normal temperature by cooling the transfer mold 1 at every use or the transfer mold 1 is fitted to cooling equipment such as water cooling equipment. Therefore, even if a process is repeated by making use of the same transfer mold 1, viscosity of the ultraviolet curing resin 3 to be formed in the guide groove can be kept at 100-200 CPS (centripoise) and the generation of bubbles can be prevented.

IPC: H02J3/18
Filed: 1990-09-14
Abstract: PURPOSE:To suppress the ripple of bus voltage at high speed, according to instantaneous overvoltage or low voltage ripple by adding auxiliary control systems, which consist of bus voltage upper and lower limits detectors and others and operate at high speeds, to the main control system for opening and closing the thyristors in stages in a group of capacitors, which operate at low speed in principle. CONSTITUTION:An upper limit detector 9 and a lower limit detector 10, which are provided with the reference set values of the upper limit and the lower limit of the reference voltage of the bus, detect the voltage over the upper limit and the lower limit of bus voltage instantaneously. Hereupon, when the sent-out voltage rises and tops the upper limit set value, the up-down counter 11 connected to the detectors 9 and 10 counts this, and a logic circuit 12 generates a signal for reducing the number of the control stages of SC capacity by one stage to a binary-coded-decimal notation circuit 21. Similarly, when the voltage drops below the lower limit set value, it generates a signal for raising the control stages of the SC capacity.

Title: Control unit for mixing of hot water and water
Inventor: UEKI KOICHI
IPC: F16K11/04
Filed: 1984-11-20
Abstract: PURPOSE:To provide a safe hot water and water mixing control unit by forcibly stopping the operation of a mixing valve until the temperature of hot water to be supplied to the mixing valve reaches a predetermined temperature or more and carrying out the hot water control by the mixing valve when the temperature of hot water to be supplied is high. CONSTITUTION:When the temperature of feed hot water within a pipeline 8 is more than a set value of supply hot water temperature setting means, an operation signal is outputted from driving means. A mixing valve 3 adjusts the mixing ratio by a deviation signal obtained from the detected hot water temperature from mixed hot water temperature detecting means 9 and the set temperature from mixed hot water setting means 10 to control the temperature of hot water to the set hot water temperature. When hot water becomes unused and supply of hot water is stopped, the flow of hot water which has been supplied through a pipeline 8 from heat source means is stopped, and hence the temperature of supply hot water is lowered by the heat radiation from the pipeline 8 and the supply hot water is converted into a cold water temperature. When hot water is resupplied, if the temperature of supply hot water is less than the set temperature, a stop signal is output from comparison means, and the operation of the mixing valve 3 is compulsorily stopped. Accordingly, the mixing ratio is left as it is set at the preceding time, and no hot water is supplied rapidly.

CONSTITUTION:Many chips 20 having same shape are formed on one substrate 1. The images of two chips 20 are detected and compared. Thus a foreign matter or a pattern defect is inspected. In this comparison inspecting method, a reference mark 22 of each chip 20 is detected in either before the start of the inspection or during the inspection, and the arrangement error of each chip 20 is obtained. Then, either of the image of the chip 20 or a detecting element 5 is shifted by the quantity of said arrangement error when the foreign matter or the pattern defect is inspected, and said image is detected. Thereafter, the difference between the images of two chips is obtained. When the signal of disagreement is detected, it is judged that the foreign matter or the pattern defect is present. For example, a detected-image shifting means 19 is provided between an objective lens 4 and the detecting element 5 on the substrate 20.

Abstract: PURPOSE:To prevent drying of an ink film and obtain a printed matter of stable quality by providing an inking device including a pair of ink kneading rollers with an ink pot where the space between rollers becomes an ink-fountain, between and an ink fountain roller which transfers a kneaded ink to a rocking roller. CONSTITUTION:An inking device 10 which is made up of two rollers, each rotating in an opposite direction to each other, includes a pair of ink kneading rollers 11, 12 and an ink fountain roller 13 which transfers ink kneaded by the ink kneading rollers to an ink rocking roller 14. A space between the ink kneading rollers 11, 12 becomes an ink fountain, maintaining a prearranged quantity of ink. An ink feed quantity can be adjusted by a contact pressure between the ink kneading rollers 11, 12, the priming frequency of the ink fountain roller 13 or a contact time between the ink kneading roller 11 and the ink fountain roller 13. By forming an ink fountain with two ink kneading rollers 11, 12, the number of rollers can be reduced and the space between the rotating rollers is made an ink fountain. Therefore, the ink is stirred and the drying of an ink film is prevented without using an agitator.

Title: Oscillation damping device
Inventor: MAEDA JUN
IPC: B63B39/02
Filed: 1996-08-28
Abstract: PROBLEM TO BE SOLVED: To stop a weight member moving a recessed curved path at a prescribed position without any impact, by providing a second magnetic body which can approach to and separate from a first magnetic body at a prescribed position of the recessed cursed path and generating a force attracting magnetism of the first magnetic body and the second magnetic body mutually by a magnetic force. SOLUTION: When a magnet 7 is lowered and approaches to a magnetic body 9 of a weight member 5, the magnetic force is gradually increased and the movement of the weight member 5 is attenuated. In the last, the magnetic force reaches the maximum so that the weight member 5 is stopped moving and positioned in the central part of a recessed curved path 3. Then, the weight member 5 has a large weight, however, the magnet 7 and the weight member 5 are not directly in contact with each other so that, when the weight member 5 is made to stop, a large impact is not applied on the magnet 7 and a bracket 15 for supporting it, etc. The weight member 5 can be thus stopped softly and the requirement to the mechanical strength of a mechanism for stopping the weight member 5 can be suppressed to low.
