    摘要: A cold cathode tube driving device using a piezoelectric transformer in which an output voltage varies depending on a frequency of an input voltage, as a booster transformer for driving a cold cathode tube, includes: a frequency dividing means which generates a driving pulse of an average frequency corresponding to frequency data outputted from a frequency setting means at a distribution cycle which is a driving pulse N cyclic period; a controller which controls a control cycle so as to perform the same driving for predetermined number of times A (A≧2) at the average frequency; and a burst pulse generating means which generates a pulse having a duty width in accordance with a dimming level externally applied thereto and having a frequency outputted from the controller.A control cycle is A times (natural number) the distribution cycle and the driving is performed A times at the same average frequency, whereby a digital driving system using the frequency distribution of the driving pulse is achieved. Consequently, a space for the driving circuit can be saved and cost can be reduced. Further, a frequency distribution system is adopted, thereby obtaining frequency resolution required for satisfactory dimming performance and lighting performance. Moreover, a burst dimming system is adopted, thereby suppressing brightness flicker seen in a tube current control system. Additionally, there is no electric power loss seen in a system in which a power source is turned on or off and further a shield circuit is unnecessary because of a system in which the driving pulse is turned on or off. In particular, the control cycle is A times the distribution cycle and the burst dimming is performed in which the driving is executed A times at the same average frequency, whereby the brightness flicker can be prevented by controlling the tube current to be constant with high dimming resolution assured.

    摘要: A winding-down side pilot port of a control valve is of a 2-port construction comprising a normal winding-down side port having a large pressure receiving area and a free fall side port having a small pressure receiving area, wherein in the free fall operation carried out by setting a motor to a small capacity, a pilot pressure of a winding-down side remote control valve is supplied to the free fall side port through a mode switching valve. Thereby, a stroke of the control valve can be suppressed so that a speed of a motor does not exceed an allowable speed.

    摘要: An injection molding method of a metal material in a liquid phase state, by which the material can be transferred, metered, and deaerated smoothly by operating the movement and rotation of the screw. After injection, retraction resistance made of the metal material that went into a clearance between the heating cylinder and screw flights is removed in advance by rotating the screw for a set number of times at a forward position. Then, the metal material in the liquid phase state is accumulated in a front chamber by forcing the screw to retract for a set distance, and applying a back pressure to the screw rotating at a retraction position, thereby starting transfer of the metal material. Subsequently, the rotation of the screw is stopped, whereupon the accumulation is completed. Then, the accumulated metal material is pressed by moving the screw forward. Injection is effected only when a material pressure reaches a set pressure within a preset forward distance of the screw, whereupon metering is assumed to have been completed.

    摘要: A user I/F unit 200 transmits an instruction given by a user to an access management unit 100 and displays data on a monitor 76. The access management unit 100 transfers requirements to a communication control unit 300 and a data management unit 400 in response to the instruction from the user, transfers data from a communications host to the data management unit 400, and outputs data from a database 410 to the user I/F unit 200. The data management unit 400 writes data into the database 410 and reads storage data from the database 410 in response to the requirement from the access management unit 100. Data transmitted from the communications host are sorted out according to communication services and stored in the database 410. The communication control unit 300 translates the requirement from the access management unit 100 to a menu number representing each communication service available from the communications host or a command and sends the translated requirement to a communication I/F unit 500. This structure enables input data to be sorted out and stored without any overlap.
