摘要： [Problem] To obtain a thermostat device with which it is possible to dull the thermosensitivity of a thermo-element thermosensitive component to coolant water and better control the opening and closing of a main valve at a selected timing by means of an electrical heater. [Solution] A thermostat device (1) comprises: a piston (3); a cylinder container (4) which operates forward and reverse with respect to the piston and further comprises a flange valve which opens and closes a main flow path of coolant water; a thermal expansion body (W) which causes the cylinder container to operate forward and reverse upon the piston with a volumetric change commensurate with a temperature change within said cylinder container; and a thermo-element assembly body (10) which is disposed within the piston and further comprises a heat emitting element (H) which applies heat to the thermal expansion body by a supply of electricity. An insulating cover (20) is disposed which is formed to cover the exterior side portion of the cylinder container which faces the coolant water. Additionally, a resinous insulating material (21) and/or an atmosphere layer (22) are selectively disposed on the interior side of the insulating cover between said insulating cover and the exterior side face of the cylinder container.

摘要： The present invention is directed to a device for sensing compressor malfunctions and disengaging the compressor from the engine's driving force upon detection of a malfunction. A malfunction is defined herein as the rotation of the compressor below a predetermined speed. In situations where the compressor is on during engine start-up, the engine's starting motor will be exerted to the extent that the engine, and hence the compressor, will not rotate at its proper speed, making engine start-up more difficult. In order for the engine start-up condition not to produce a malfunction detection and erroneously disengage the compressor from the system, a malfunction override circuit is provided. The override circuit comprises a capacitor which is discharged through a transistor connected to the relay for controlling the current to the clutch coil. The relay remains closed due to this capacitor voltage, and the compressor remains engaged, thereby overriding the malfunction detector during engine start-up.

摘要： There is disclosed an electromagnetic clutch having a rotation detecting device. The electromagnetic clutch has a balance weight which is disposed on the outer end surface of a hub connected to a driven shaft. The detecting device for detecting the rotation of the balance weight is located at the position which faces toward a circumferentially discontinuous part of the balance weight. The construction of the above mentioned electromagnetic clutch is very simple and easy to manufacture. Also, the rotation detecting device can be put on or removed easily.

摘要： An internal combustion engine cooling device includes a piston fixedly mounted within a device housing coupled to a plurality of flow paths through which cooling water flows, the piston disposed facing the interior of the device housing; a cylinder container that advances and retreats relative to the piston and has a flange valve that opens and closes a main flow path of the cooling water; a thermal expansion unit provided within the cylinder container that causes the cylinder container to advance and retreat due to volumetric changes attendant upon temperature changes; and a heat-emitting element provided within a piston casing that heats the thermal expansion unit when supplied with electricity. An insulating cover is provided to the exterior of the cylinder container at a portion of the cylinder container disposed facing the cooling water.

摘要： A switching regulator for use with various kinds of electric and electronic equipment as a DC stabilizing power source. The switching regulator has a switching element implemented as an n-p-n switching transistor, an overcurrent detecting circuit for detecting an overcurrent ascribable to a fault, and a start delaying circuit for, after the switching transistor has been caused into an inactive state, feeding to the transistor a starting current which is delayed by a predetermined period of time. When the fault is removed, the switching transistor resumes its turn-on and turn-off operations immediately so as to restore the switching regulator to normal rapidly.
