摘要:
A torque limiting device for a compressor. An input shaft of the compressor is connected to the torque limiting device so that the power source driving the compressor will not be affected if abnormal conditions cause the compressor to generate an excessive load. A flexible connector is located between the power source and the compressor. The flexible connector is deformed when torque is applied to the compressor input shaft. When the applied torque exceeds a predetermined value, a spring is permitted to expand axially, which uncouples the compressor from the power source. The torque at which the device uncouples is stable and predictable.

A compressor mounted on a vehicle is disclosed. The compressor includes an apparatus for transmitting rotational power from an engine to drive shaft of the compressor via a pulley. The apparatus has a spring coupled to one of the pulley and the drive shaft. A deformable ring is coupled to the other one of the pulley and the drive shaft. The deformable ring is deformed by heat. The spring and the deformable ring are being held in abutment against each other by the force of the spring so as to transmit the rotational power to each other. A contact ring is interposed between the spring and the deformable ring. The contact ring has a rigidity larger than that of the deformable ring. The spring and the contact ring frictionally contact one another to generate the heat that deform the deformable ring when load generated in the drive shaft is in excess of a predetermined value.
摘要:
A heating apparatus for a vehicle with a simplified piping structure in a fluid pressure operating system, to a heat exchanger while preventing a pulsation of the operating fluid in the system from being directly transmitted to a cabin, thereby suppressing an occurrence of a noise in the cabin. A fluid pressure operating system includes an oil pump 12 rotated by an engine 21 and an actuator 20 operated by the operating fluid issued from the oil pump 12. A heat exchanger 39 is arranged between an outlet of the oil pump 12 and the actuator 20. Heat generated at the oil pump 12 in the fluid pressure operating system 11 is passed to the engine cooling water at the heat emitter and is used for heating the cabin.

A heating system for a vehicle is provided which does not require a large boarding space in an engine room very much, which can be manufactured at a reduced cost, and which can fully heat a passenger compartment of a vehicle when an engine is started. For instance, in the vehicle heating system, a water pump (WP) and a viscous heater (VH) is incorporated into an installation housing (1), a plate (2) and a cover (3) which are bonded to a cylinder block of an engine. The water pump (WP) and the viscous heater (VH) are driven by a drive shaft (11) which is shared by them. Moreover, the viscous heater (VH) includes an auxiliary water jacket (WJ.sub.2). The auxiliary water jacket (WJ.sub.2) is communicated with a main water jacket (WJ.sub.1) of the engine by way of a pump chamber (4) of the water pump (WP), and is further communicated with a heater core for heating a passenger compartment of a vehicle.

A viscous heater is provided which can securely inhibit a viscous fluid from leaking even after extended use. For instance, the heater is provided with a shaft-sealing apparatus which seals a driving shaft between a heat-generating chamber and a bearing apparatus. The shaft-sealing apparatus is arranged so that it is cooled by a front water jacket which is disposed adjacent to it.

An optical semiconductor device includes an optical semiconductor element, a semiconductor region, and a buried layer. The optical semiconductor element is formed on a semiconductor substrate. The semiconductor region opposes the optical semiconductor element and essentially surrounds the optical semiconductor element to form walls. The buried layer is arranged between the walls of the semiconductor region and the optical semiconductor element and formed by vapor phase epitaxy. In this optical semiconductor device, a distance between the wall of the semiconductor region and a side wall of the optical semiconductor element is larger in a portion in which the growth rate of the vapor phase epitaxy in a horizontal direction from the side wall of the optical semiconductor element and the wall of the semiconductor region is higher.
摘要:
A viscous fluid type supplementary heat generator having a housing assembly defining a fluid containing chamber including a hermetically sealed heat generating chamber in which a viscous fluid is filled to generate heat when the viscous fluid is subjected to shearing action applied by the rotation of a rotor element rotatably arranged in the heat generating chamber. The fluid containing chamber has a predetermined substantial volume with respect to which the volume of the viscous fluid filled in the fluid containing chamber is set at a value between 50% through 70%, i.e., the filling rate of the viscous fluid relative to the substantial volume of the fluid containing chamber of the viscous fluid type heat generator is determined to be a value between 0.5 through 0.7. The determination of the filling rate of the viscous fluid is made so as to protect an oil sealing device sealing the heat generating chamber from being damaged or broken by an excessive pressure prevailing in the heat generating chamber.
摘要:
As a viscous fluid (F) contained in a vehicular heat generator provided with a rotor (33), a non-Newtonian fluid having an apparent viscosity that decreases as the shear rate of the rotor (33) increases (e.g., a kind of silicone oil) is employed. The nominal viscosity of the viscous fluid (F) is in the range of 10,000 cSt to 200,000 cSt. If such viscous fluid is employed, the viscous fluid (F) maintains its shear heat generating function over an extended period even under circumstances where the fluid (F) is subjected to over-shearing by over-rotation of the rotor (33). In addition, low-temperature starting of the rotor is facilitated.
摘要:
A viscous fluid type heating apparatus capable of achieving both reliable prevention of deterioration in the heat-generating performance of a viscous fluid and reliable prevention of leakage of the viscous fluid from the apparatus, and having a heat generating chamber provided with a first and a second storing region for storing a silicone oil to avoid an application of a shearing action from a rotor element to the viscous fluid and a heat generating gap. The silicone oil is held in the heat generating chamber so that it is able to flow between the heat generating gap and the first storing region which is directly affected by a thermal condition in the heat generating gap. The second storing region is substantially separated from the first storing region and is not directly affected by the thermal condition in the heat generating gap. The flow of the silicone oil between the first and second storing regions is adjustable by a movable element.
