Title: Apparatus to measure physical constants
Inventor: KUWAYAMA TETSUO
IPC: G01N21/45
Filed: 1977-11-05
Abstract: PURPOSE: To measure the peak interval of interference fringe at high precision by displacing an interference fringe pattern similar to at least one peak relatively with respect to the plane on which interference fringe is formed as an index.  
     CONSTITUTION: The meausuring object having at least two planes is illuminated by a luminous flux possessing wavelength width, and white interference fringe is formed in an interferometer part consisting of polarizer 54, Wollaston prism and analyzer 56. Making use of the interference fringe, physical constants such as film thickness and refractive index are measured. The Wollaston prism is divided into  an upper part P' and a lower part P", which are identical in structure, and the  prism P' is secured while the prism P" is moved in the arrow direction by a micrometer head 60. As a result, the interference fringe is divided into the upper half and  the lower half by a datum line L which expresses the boundary of prisms P' and  P". Hence, by adjusting the micrometer head 60 until the fringes of the upper and  lower interference fringes coincide, the peak interval of the interference fringe may  be measured.

Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display element formed by using antiferroelectric liquid crystals with which the stable assigning of intensity levels is possible. SOLUTION: A liquid crystal layer 21 which exhibits an antiferroelectric phase in a bulk state and forms a ferri phase while the layer is held sealed between substrates 11 and 12 and an electric field is kept impressed thereon is sealed between the substrates 11 and 12. Either of the liquid crystal molecules in a first orientation state and the liquid crystal molecules of a second orientation state switch to the other along the cone drawn by the liquid crystal molecules of a chiral smectic CA phase according to the polarity and size of the impressed voltage. The ratio of the liquid crystals of the first orientation state and the liquid crystals of the second orientation state, therefore, changes according to the polarity and magnitude of the impressed voltage and the directors change continuously according to the impressed voltage.  Then, the assigning of intensity levels is made possible by arranging polarizing plates 23, 24 across the substrates 11, 12.

Abstract: PURPOSE:To attain the reduction of the driving torque of a rotary axis by providing a specified gap between a peripheral wall opposite to the side of carrying fine particle from a storage room to a room to be supplied and the peripheral surface of a rotating member. CONSTITUTION:A room A is formed of a toner tank 1 and a room B is formed of a developing tank 2 respectively, and the rotary axis 3 is set on the border part between both rooms A and B. The rotary axis 3 properly rotates counterclockwise and supplied the toner of the room A to the room B so as to keep the density of the toner of the room B a specified value. Between the peripheral wall of the border part opposite to the side of carrying the toner from the room A to the room B and the peripheral surface of the rotary axis 3, the gap 10 whose size is the one the toner does not flow out to the room B is formed. Since the torque of the rotary axis 3 can be reduced, thus, the cost-down can be enhanced by minimizing a driving motor.

Filed: 1992-05-26
Abstract: PURPOSE:To switch a valve body of a four-way switching valve to a normal state and to prevent its switching defect by delaying a predetermined time from the time of starting a compressor to open a switching valve provided in a bypass circuit, and closing it after a predetermined time is elapsed. CONSTITUTION:A bypass circuit to be connected to an inlet of an accumulator from a discharge side tube of a compressor through a switching valve is provided. The valve is opened after a predetermined time from the start of the compressor, and closed after a predetermined time is elapsed. The valve is so constructed as to be opened after the predetermined time from the start of the compressor, a pressure difference thereby reaches an operating pressure of the valve, and a valve body of the valve is switched to a normal state to prevent its switching defect. For example, when an operation switch 11 is closed in an electric circuit diagram of an air conditioner, an electromagnetic switch 12 for a compressor is excited, and a timer coil 13 is simultaneously excited. Since a contact 14a is a time limiting operating and time limiting resetting contact, a coil 15 for the valve is excited when the valve is closed after 10 sec from when the coil 13 is energized, and the valve is opened. After three min, the contact 14a is opened, the coil 15 is not energized, and the valve is not closed.

Abstract: PROBLEM TO BE SOLVED: To provide a circuit resetting mechanism which can simultaneously reset plural circuits, operated with further inexpensive constitution by supplying power from different power source systems and to provide a disk drive device using the circuit resetting mechanism. SOLUTION: The collector of a transistor 4 is impressed by a voltage obtained, by dividing the power source voltage Vcc1 of a first power source system by resistors R1, R2; its base is impressed with a voltage obtained, by dividing the power source voltage Vcc2 of a second power source system by resitors R3, R4; and its emitter voltage is impressed on a reset circuit 3. When the emitter voltage becomes less than a specified reset-judging voltage, the reset circuit 3 outputs a reset signal to reset each circuit.  When either Vcc1 or Vcc2 lowers below a voltage which requires the circuit to be reset, each value of the resistors R1-R4 is selected, so that the emitter voltage is less than the reset-judging voltage to realize a resetting mechanism which has a function equivalent to that of the mechanism, having installed a reset circuit for individual power source systems using an further inexpensive constitution.
