Title: Power source protective circuit
Inventor: SHIBAYAMA TSUTOMU
IPC: H02H3/05
Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To reduce the influence of the load of a small DC power receiving circuit when the load short-circuits or the load is heavy on a power supply source in a circuit which protects a power source when the load becomes abnormal. SOLUTION: In a breaking circuit 4 which connects a power supply source to a load 1A, a capacitor C1 is fully charged after a solid-state relay SSR1 is turned on by making the primary-side current i1 of the relay SSR1 to flow for a period of time longer than the operating time of a rush current suppressing circuit 2 at the time of turning on the circuit 2 when the power supply source is turned on while the capacitor C1 is fully discharged and, when the power supply source is turned off while the capacitor C1 is fully charged, the relay SSR1 is turned off and, at the same time, the capacitor C1 is fully discharged.  When a load 1A short-circuits or the load 1A becomes heavy while the power supply source is turned on, the relay SSR1 is turned off so as to disconnect the load 1A and, at the same time, to prevent the discharge of the capacitor C1 by using the current in the charging route of the capacitor C1.

Title: Oil tank for dry sump
Inventor: MORITA HIROSHI
IPC: F01M11/03
Filed: 1989-09-08
Abstract: PURPOSE:To completely separate air from oil by centrifugally separate air within oil, joining oil with air excluded with oil in a tank in a state that swirl flow is suspended, and thereby concurrently sucking oil out with air mixing prevented. CONSTITUTION:Oil is led to a cyclone type separator 9 arranged on the upper section of an oil tank main body 8 so that air is removed by means of a centrifugal separating method. Then, air free oil is joined with an oil level 18 from the lower end 9a of the separator set beneath the oil level 18 with no scattering into a space. In this case, swirl flow liable to be generated at the upper layer section of stored oil is prevented by a radially shaped vertical baffle 12. This can thereby prevent the core of air bubbles from being formed at the center of swirl flow. On the other hand, oil is sucked out of an oil suction port 14 at the bottom of the oil tank main body 8. In this case, a disc type horizontal baffle 13 prevents air from being mixed.

Filed: 1982-12-23
Abstract: PURPOSE:To eliminate the slip between a roller and a traveling surface and to improve the accuracy in detection by constituting a roller supporting member and a base member facing said member at a prescribed spacing of plural parallel springs at their respective two ends. CONSTITUTION:Parallel springs 71, 72, 73 and 74 are respectively fixed at one end to a base 3 and at the other end to a roller supporting member 4, respectively to position the supporting shaft 61 for the roller 6 at a right angle to the moving direction of a table 2 and in parallel with a rail surface 51, so that the contact roller 6 contacts under suitable contact pressure with the surface 51. If the spring constant of the springs is made as small as possible, the change in the press contact force of the roller 6 with the surface 51 owing to the flatness and undulation of the surface 51 and the eccentricity of the roller 6 is decreased and jumping and slip can be prevented. If a bearing operating on compressed air is used, the slip of the roller 6 is eliminated. The accuracy in detection is thus improved.

Abstract: PROBLEM TO BE SOLVED: To share a working area for a horizontal working shaft and a vertical working shaft, then simplify the construction and improve the efficiency of assembling work by mounting the horizontal working shaft and the vertical working shaft on one and the same elevation table, and further, mounting second horizontal working shaft. SOLUTION: A bridging roller 14 is extruded into a transport path 4 by driving a cylinder 13. If a wood 9 being transported on the roller 3 of the transport path 4 comes into contact with a stopper shifted to a previously specified position, and is stopped for positioning, an elevating member 26 is moved vertically by a servo motor 23. Next, the lateral and the upper surface of the wood 9 are worked by a first and a second horizontal working shaft 32, 37 or a vertical working shaft 42 through the respective drive of cylinders 33, 43. Consequently, the working area of both horizontal working shafts 32, 37 and vertical working shaft 42, is shared, so that the wood no longer need be positioned to the horizontal working shafts 32, 37 or the vertical working shaft 42. Thus the control of shifting the horizontal working shafts 32, 37 and the vertical working shaft 42 is simplified.

Title: Intake throttle device for cooling circuit
Inventor: ONO JUNICHI
IPC: F04B49/06
Filed: 1990-09-04
Abstract: PURPOSE:To attain good cooling capability control and lubrication by providing a throttle control function securing the minimum intake pressure exceeding the intake pressure loss in response to the rotating speed of a compressor on a throttle control means. CONSTITUTION:A control computer C calculates the rotating speed per unit time of a compressor l based on the rotation detection information, selects the feed current value in response to the rotation speed, and directs the output of the feed current value to a driving circuit 20. As a valve body 11 is moved upward, the refrigerant gas pressure, i.e., the intake pressure, on an output passage 9b side is increased, and the refrigerant gas easily flows into the compressor l. The feed current value is set smaller as the rotating speed of the compressor 1 is increased and larger as it is decreased. The minimum intake pressure value specified by the upward motion position of the valve body 11 is set so as to exceed the intake pressure loss at any rotating speed. The refrigerant gas invariably flows into the compressor l, and good cooling capability control and good lubrication in the compressor 1 can be attained.
