Title: Ac-dc converter
Inventor: MASUDA YOICHI
IPC: H02M1/14
Filed: 1985-06-20
Abstract: PURPOSE:To reduce the input current peak value and miniaturize the converter by providing an intermediate tap to a choke coil to which switching elements are connected respectively, and switching on and off one of the elements thereof in accordance with the input commutation voltage value. CONSTITUTION:In an AC-DC converter where the commutating output of an AC power source 1 is transformed into that of direct current through a choke coil 3 and an output commutation smoothing circuit 8, one intermediate tap or more are provided for the primary winding 4a-4d of the choke coil 3. Between each intermediate tap and between the end of the primary winding and one input line, switching elements 6a-6d are connected respectively. Then by a controlling circuit the input commutation voltage value is detected, in accordance with which one of the elements 6a-6d is selected to do switching. In this way the peak value is reduced and the efficiency improved, since the inductance value of the choke coil 3 is always kept at a proper value.

Filed: 1983-07-21
Abstract: PURPOSE:To avoid unevenness of the leading edges of sheets and to reliably separate and transport a sheet by relatively moving a sheet stacking table and a sheet leading edge aligning and regulating plate forward and backward in a sheet separating device of a copying machine or the like. CONSTITUTION:When a solenoid clutch 7 is operated by a signal from a control device not shown, a cam 8 is rotated by driving turning torque transmitted thereto through gears G1, G2 and a driven shaft X2, so that an aligning and regulating plate 3 is moved to a two-dotted line position through a guide pin 5 against a spring 9. Subsequently, when an eccentric cam 8 separates from the pin 5, the aligning and regulating plate 3 is restored to the initial position by the spring 9. By repetition of such operation, the leading edges of sheets P are aligned. After a fixed time for aligning operation, the clutch 7 is disconnected to operate a rotor 2b, a sheet feed roller 33d and a pair of rollers 33f, therby separating and transporting a sheet. Thus, the aligning state of leading edges of sheets can be improved, and the sheets can be separated and fed out reliably.

Title: Hydraulic power transmission coupling
Inventor: SUZUKI SATORU
IPC: F16D31/02
Filed: 1989-05-26
Abstract: PURPOSE:To shorten the time for returning from a locked condition by leaking a hydraulic oil in a high-pressure chamber to a low-pressure chamber when a detecting mechanism, provided in a main line for connecting to delivery and suction lines of fluid, is moved at a specified delivery pressure or a specified temperature to close an orifice. CONSTITUTION:When a delivery pressure reaches a specified value, an orifice value 24 is moved to the right against a spring 25 until it comes in contact with the staged portion of a rotor 12. Although a needle valve 26 closes an orifice 23, there exists a clearance 40 between the orifice valve 24 and the needle valve 26 and a hydraulic oil in a high-pressure chamber 16A leaks to a low-pressure chamber 16B through the clearance 40. Accordingly, when a load torque on a coupling is removed, the orifice valve 24 returns to the original position by the spring 25 to shorten the time for returning from a locked condition.

Abstract: PURPOSE:To prevent the deformation of a recording medium by shunting a head from the recording medium by means of a prescribed shunting means when a recording/reproducing device is not used and avoiding contact between the head and the recording medium. CONSTITUTION:A cylindrical part 7a of a magnetic head carrier 7 is supported rotatably and slidably by a guide shaft 10, and an arm part 7b is in contact with a guide shaft 11 via an offset spring 20.
