Title: One way clutch
Inventor: MIZUNO MITSUO
IPC: F16D41/067
Filed: 1990-04-04
Abstract: PURPOSE:To prevent an one way clutch from causing such malfunction as the load of the axis of rotation to increase unnecessarily, the fatigue of a spring to accelerate and further to generate noise, and the like by providing a spacer, that will slide along the outer circumference surface of the axis of rotation, in each gap between the outer circumference surface of the axis of rotation and a plural number of magnet. CONSTITUTION:When an axis of rotation 1 is making a normal rotation in an one way clutch, a roller 5, which is a magnetic body and is in contact with an outer ring 2 and the outer circumference surface of the axis of rotation 1 for being attracted by a magnet 6, causes a wedging effect between the axis of rotation 1 and the outer ring 2 thus the one way clutch is engaged. When the axis of rotation 1 is making a reverse rotation, the wedging effect vanishes and the engagement of the one way clutch is released. Further, each spacer 8, 11, which fitted in a gap (a) made between the outer circumference surface of the axis of rotation 1 and each magnet 6, functions as an auxiliary bearing for the axis of rotation 1.

Title: Closing device for oil-pressure circuit for inertia-mass driving
Inventor: TANAKA HIDEAKI
IPC: F15B13/01
Filed: 1981-06-12
Abstract: PURPOSE: To prevent the actuation of an oil-pressure motor by switching valves by using a system in which an oil-pressure motor driving great inertia mass is connected with an oil-pressure pump by a switching valve and two pilot operation type valves, and by detecting the discharge of the oil-pressure pump, the valves are operated.  
     CONSTITUTION: The pressure oil discharged from an oil-pressure pump 2 is supplied through a manual switching valve 4 and pipelines 5, 12, and 13 to an actuator 1 to drive great inertial mass, e.g., the rotator of an oil-pressure shovel, etc. Pilot operating valves 34 and 35 are provided between the pipeline 12, the pipeline 13, and the switching valve 4 to make up a closed circuit. The pressure oil discharged from an auxiliary oil-pressure pump 30 is raised up to the pressure of a setting valve 31, the valves 34 and 35 are switched from closed position E to open position F through the pilot pipeline 36, and thereby the operation of the oil-pressure motor 1 by the switching valve 4 is made possible. In this case, when a prime mover 3 is stopped, said valves 34 and 35 are turned into the closed position E and the pipelines 12 and 13 of the oil-pressure motor 1 are interrupted. Thus, the actuation of the oil-pressure motor 1 by manual switching valve 4 can be prevented.

Title: Temperature sensor inside heating vessel
Inventor: SHIMAZAKI SHINJI
IPC: G01K1/16
Filed: 1995-04-14
Abstract: PURPOSE: To accurately measure heating temperature applied to an object to be heated, in the heating in which heat radiation is jointly used, by fitting a platelike heat resisting material to a temperature sensing part. CONSTITUTION: A heat-resisting material 11 made of a metal, ceramics, heat- resistant resin or the like which has a rectangular plate shape slightly shorter than the inside breadth of a furnace body 1 is fitted to a temperature sensing part 3a inside the furnace body 1. Then, the gas heated by heaters 2 is moved by convection inside a heating vessel 14 for heating the object 4 to be heated, the furnace body 1, and the material 11. At the same time, the object 4 and the material 11 are also irradiated and heated by radiation being radiated from the surfaces of the heaters 2 and the furnace body 1. As a result, the material 11 is heated both by the transferred heat due to convection and by the radiation heat, and the heat is transferred to the sensing part 3a of a temperature sensor 3, so that the heat can be accurately measured.  Further, if the material 11 is made up of the material having the same quality and the same surface condition as the object 4, or made up of the material having nearly the same characteristic as the contraction coefficient of the object 4 due to radiation, further accurate measurement can be achieved.

Title: Automatic power source changeover mechanism for vehicle
Inventor: KOJIMA MASAHIRO
IPC: F16H59/58
Filed: 1987-04-14
Abstract: PURPOSE:To prevent any operating failure at the load side due to a drop in starting voltage to a motor by supplying the load side with an operating voltage within the specified time with the on-operation of an auto-emergency steering switch, and starting the motor after the elapse of the specified time. CONSTITUTION:When an auto-emergency steering switch is turned on, a first timer 9 is held as long as the specified time, so that a solenoid 6c is excited and a battery transfer relay 6 is turned off. At this time, respective batteries 1 and 2 at the left feed an operating voltage to the load side (A) of a transmission control circuit or the like. On the other hand, a second timer 10 operates after the elapse of the specified time since the switch 8 has been turned off, so that a solenoid 7c of a motor relay 7 is excited after the elapse of the specified time and a motor 5 is thus started. With this constitution, such a fear that a voltage drop occurs at time of motor starting and the load side (A) comes to any operating failure is preventable.
