Patent JP-H0354100-A (JP)
Title: Accumulator
Inventor: MATSUSHITA TADASHI
IPC: B64G1/50
Filed: 1989-07-20
Abstract: PURPOSE:To prevent entrance of inactive gas through simple constitution and to perform efficient heat transport of a liquid loop in gravity-free environment by a method wherein working fluid is separated and contained in two spots in the vicinity of working fluid outlet and inlet at the ends across a liquid storage tank, and steam is contained at the intermediate part of the working fluid in a state to separate gas away from liquid. CONSTITUTION:Working fluid 11 in an amount more surplus than a total content volume is guided to a fluid loop through a line 14 and a first line 13 and contained in a liquid storage tank 10 in a state to separate steam 12 away from working fluid. When the vaporizing and condensing temperature of a liquid loop is increased, a command signal is inputted from a command part to a regulating control part 19. In which case, the control part 19 heats a second line 15 by charging a heater 16 with a current, steam is generated at the line 15 to feed steam to the steam containing part of the liquid storage tank 10. As a result, a pressure in the liquid storage tank 10 is increased, and a pressure in the liquid storage tank 10 is detected by a pressure detecting sensor 20. When the pressure attains a set value, the control part 19 disconnects the feed of a current to the heater 16 to stop drive, and a pressure in the liquid storage tank 10 is held at a set value.

Abstract: PURPOSE:To hold pressure difference between two chambers and to prevent generation of a flaw on the surfaces of a plate material by lengthening the conveying passage of the plate material which is surrounded with the upper and lower plates and the right and left sealing plates corresponding to the gap between the plates and bringing the upper surface of the plate material into contact with the guide rolls and conveying the plate. CONSTITUTION:The guide rolls 7a, 7b are provided to the front and rear ends of the carrier direction of a plate S on the upper plate 5 and the shafts of the rolls 7a, 7b are made parallel to the surface of the plate S and made rectangular to the carrier direction of the plate S and provided with a gap from a lower plate 6. Furthermore the sealing plates 8a, 8b are provided to both side ends of the plates 5, 6 in the conveying direction of the plate S and these plates 8a, 8b bury the gap of both plates 5, 6 and closely adhere to the side walls 9a, 9b of two chambers. Therefore the plate S can be conveyed with its lower surface being in noncontact state and when coating treatment is applied on the lower surface thereof, a flaw and dirt are not caused. Further ventilation resistance of gas between two chambers A and B can be made large by the length of the passage of the plate and pressure difference between two chambers can be held.

Title: Control method for step motor for driving throttle valve
Inventor: TOGAI KAZUHIDE
IPC: H02P8/20
Filed: 1988-07-29
Abstract: PURPOSE:To perform reversing without overshooting and a delay by a method wherein when a step motor is reversed, a time of a present exciting phase is prolonged by a time longer than an approximate half period of shortmost free vibration, and reversing excitation is effected after a speed phase is reversed due to free vibration. CONSTITUTION:In a block 1, when the present position of a rotor is compared with a target phase and reversing is effected and decision is made to perform reversing, starting from a stop is executed when a motor is not under high speed running. When it is under high speed running, and when a speed is, for example, 1/2 pulse/sec (PPS) of maximum free vibration and exceeds 600 PPS, excitation is held, and the phase of a speed is inverted with free vibration. Phase inversion occurs at intervals of approximate a half period of free vibration since a deviation between a speed under continuous drive and a position is approximately specified and a speed coincides with a drive direction even when free vibration is started. In a block 4, a time of a present exciting phase is prolonged by a time longer than an approximate half period of shortmost free vibration, and reversing excitation is effected after a speed phase is reversed due to free vibration. This constitution enables execution of reversing without an overshooting amount and a delay time.

Abstract: PURPOSE:To obtain the die for microlens array having varied curvatures at low cost and with good accuracy by forming the plated metallic layer to the projecting shape having a spherical surface with utilizing the surface tension of a molten metal. CONSTITUTION:The resist film 3 having the same diameter with the diameter of the micro lens to be manufactured in an array shape is formed on a metallic plate 1. An insulating film 4 is formed with vacuum evaporation or spattering on the resist film 3 and metallic plate 1. The metallic plate 1 is exposed by peeling the resist film 3 and with removing the insulating film 4 on the resist film 3 together as well. The metal layer 5 of tin, etc. is electroplated on the metallic plate 1. With heating the metallic plate 1 at the temp. higher than the melting point of the metal layer 5 and lower than the melting point of the metal plate 1, the surface of the metal layer 5 is rounded like the projecting part having a spherical shape. The radius of curvature is determined by the cubic volume of the molten metal and the diameter of the metal film. Consequently by controlling the thickness of the metal layer at the plating time the lens die having varied curvature is freely obtd.

Title: Image memory
Inventor: KOMINE TAKAYUKI
IPC: G09G5/39
Filed: 1986-08-13
Abstract: PURPOSE:To switch between the vertical position and the horizontal position of an image by switching between a counter and an address line while providing the function of a dual port to an image memory. CONSTITUTION:A control signal generator 2 produces a control signal of a memory and a memory control 3 produces an address signal and a selector switching signal. Both RAM memories A5 and B6 store image data. An address selector 8 allocates addresses to memories A5 and B6 in response to the switching signal. A control signal selector 9 allocates the control signals to both memories A5 and B6. A data selector 12 allocates the image data to memories A5 and B6 and carries out writing and reading actions alternately via a CPU 20 to perform a dual port action. A counter and an address signal is switched with each other within the control 3 and therefore the vertical and horizontal positions are switched with each other for both memories A5 and B6. Thus the vertical position is converted into the horizontal position for an image.
