Abstract:
A viscous fluid type heat generator including a housing assembly defining a heat generating chamber and an additional chamber communicated through fluid passageway means with the heat generating chamber, these chambers forming a fluid-tight chamber for accommodating a viscous fluid, and a heat receiving chamber for permitting a heat exchanging fluid to circulate therethrough to receive heat from the heat generating chamber. A rotor element is mounted on a drive shaft for rotation together therewith in the heat generating chamber with a gap defined between the inner wall surfaces of the heat generating chamber and the outer faces of the rotor element. The fluid passageway means includes a fluid withdrawing passageway for withdrawing the viscous fluid from the gap into the additional chamber and a fluid supply passageway for supplying the viscous fluid from the additional chamber into the gap. The fluid withdrawing passageway includes a withdrawing channel formed along one of the inner wall surfaces of the heat generating chamber. The withdrawing channel extends up to and opens to an outer peripheral region of the heat generating chamber to communicate the outer peripheral region with the additional chamber.
Abstract:
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.
Abstract:
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.
Abstract:
A discharge tube of the type wherein a voltage is applied across a pair of electrodes to cause a discharge between the anode side electrode and the cathode side electrode. In the new discharge tube, opposing end portions of the pair of electrodes are formed into a non-acute configuration, and a large number of concave or convex portions are formed on a surface at least of the cathode side electrode. A stabilized high discharge voltage can be obtained from an initial stage of discharging with a comparatively small distance between the electrodes. Further, since the surface area of the electrodes is great, exhaustion of the electrodes are dispersed, and the electrodes are superior in durability. Further, since the distance between the electrodes is small, the discharge maintaining voltage is low and the energy loss is decreased.

To provide a conductive resin composite high in conductivity and moldability and low in electric resistance, intercalation compound composed of graphite fiber (having a three-dimensional crystal structure such that hexagonal net planes of carbon are arranged substantially in parallel to a fiber axis and in annular ring growth fashion) and fluorine or transition element fluoride are dispersed in synthetic resin.
Abstract:
A lean burn internal combustion engine has a basic fuel injection amount calculated and multiplied by a lean correction factor, the resulting amount controls the air fuel ratio of the engine. The lean correction multiplied by factor is calculated from a first map based on intake pressure and engine speed. However, when the degree of opening of the throttle valve is larger than a predetermined value, a second correction map based on the degree of opening of the throttle valve and engine speed is used to obtain the lean correction factor. When the second correction map is employed, an ignition timing map based on the degree of opening of the throttle valve and engine speed is used to obtain an ignition timing; instead of the usual ignition timing, based on intake pressure and engine speed.
Abstract:
A high tension cable device with a series gap wherein an extraordinary discharge such as a creeping discharge which may occur along an outer face of a glass tube of a discharge tube is prevented effectively and a process of producing the same are disclosed. The high tension cable device comprises an electrically insulating tubular casing and a connecting terminal for the connection to a terminal of an ignition plug of an engine. The connecting terminal is fixedly fitted in the inside of an end portion of the casing, and a high tension cable is fitted in the other end portion of the casing. An additional function part such as a discharge tube for the formation of a series gap is mounted in the inside of the casing and coupled at an end thereof to the connecting terminal and at the other end thereof to the high tension cable, and an electrically insulating resin material is filled in a spacing in the inside of the casing.
