摘要:
An inner fin (1) of a heat exchanger has, on front and rear faces thereof, protruding ridges (2, 3) protruding in opposite directions to each other. Grooves (4, 5) to serve as passages of a heat exchange medium are formed between the adjacent protruding ridges (2, 3). In wall portions (6) forming these protruding ridges (2, 3), cutout windows (10, 11) are formed to allow the adjacent passages to communicate with each other. Further, protruding weir portions (12, 13) are provided at bottoms of entrances of the cutout windows (10 and 11), so that the heat exchange medium hits against the weir portions to promote difference and stirring of the heat exchange medium, thereby enhancing heat exchange efficiency.

A valve timing control apparatus includes a phase holding mechanism for holding relative phase between an inner peripheral member and an outer peripheral member to a predetermined intermediate phase between a most advanced angle phase and a most retarded angle phase, a fluid feeding device for feeding fluid to an advanced angle chamber or a retarded angle chamber through a first fluid passageway or a second fluid passageway, and a fluid control valve for switching over the passage for the fluid discharged from the fluid feeding device to either the first fluid passageway or the second fluid passageway and controlling the feeding amount of the fluid. The phase holding mechanism is configured to have its holding state for holding the relative phase released by a fluid pressure of the first fluid passageway or the second fluid passageway to whichever the fluid control valve starts the feeding of the fluid. After releasing of the holding state of the relative phase, this releasing state is maintained by a fluid pressure applied thereto from at least one of the first fluid passageway and the second fluid passageway.

Combination turn-signal and hazard-warning switch means for an automobile wherein a turn-signal movable contact member has two operating portions disposed along a row of stationary contact members on an insulator plate and a hazard-warning movable contact member is movable into an operative position along said row of stationary contact members. The combination switch means thus constructed is capable of reducing the number of the stationary contact members required therefor and space required for the arrangement of the stationary contact members and capable of being formed very compactly.

A heat exchanger 1 includes a pair of tanks 2 and 3 arranged a certain distance apart from each other, a plurality of tubes 4a whose both end portions are connected with the pair of tanks 2 and 3, a long receiver tank 5 arranged along and adjacently to the tank 3 and communicatably connected with the tank 3, and a reception member 20 contained in the receiver tank 5. An upper opening end portion 13b has an opening portion at one side in a longitudinal direction of the receiver tank 5 and having a reduced diameter, and a block member 15 blocks the upper opening end portion 13b. An entire of the heat exchanger 1 except the reception member 20 and the block member 15 are integrally formed by a brazing process. The reception member 20 is inserted through the upper opening end portion 13b and arranged in the receiver tank 5 after the brazing process, and then the block member 15 is joined by brazing with the upper opening end portion 13b after the reception member 20 is inserted and arranged therein.

A tank of heat exchanger comprises a tank body and a metal member. The metal member is at least one of a pipe member, a header plate member, an end plate and a filler neck member. The tank body is made of a metal and shaped like a channel member including a base wall and opposed side walls between when the base wall extends. The metal member is hermetically secured to a given portion of the tank body by partially welding the metal member to the given portion and then brazing the metal member to the given portion.

A valve timing control device includes a driving side rotational member, a driven side rotational member, a fluid pressure chamber, a parting portion dividing the fluid pressure chamber into an advanced angle chamber and a retarded angle chamber, a restriction member, a restriction recessed portion for restricting a displacement of a relative rotational phase within a range between a most advanced angle phase or a most retarded angle phase and a predetermined phase when the restriction member is inserted into the restriction recessed portion, and a restriction cancellation passage, wherein a communication between the accommodation portion and one of the advanced angle chamber and the retarded angle chamber via the cancellation passage is interrupted at least when the restriction member contacts one of end portions of the restriction recessed portion, and the restriction member is restricted so as not to move over the other one of the end portions.

A remote control key that may easily be disassembled while preventing theft of its transponder. The remote control key includes a transmitter for transmitting a signal to remotely control locking and unlocking of a door. The transponder transmits a predetermined ID code. A housing retains the transmitter and the transponder. A pad is formed on the housing to operate the transmitter. A seal seals the transponder that is retained in the housing. The seal and the pad are formed from the same material.

A shift lever device is provided that includes a shift lever, an interlocking member movable from a first position to a second position, a detent member that abuts the interlocking member at the first position and restricts the shifting operation if the shift lever is shifted from the parking range position to another range position, a restricting member movable between a shift-lock state and a shift-lock released state for allowing or preventing the interlocking member to move from the first position to the second position; a manual operation mechanism which allows the restricting member to be manually moved from the shift-locked state to the shift-lock released state, and an actuator connecting member that moves integrally with the restricting member due to the operation of an actuator. When the restricting member is placed in a shift-locked state, it can be moved by the manual operation mechanism into the shift-lock released state. The shift lever device thus allows the release of a shift lock by a manual operation, and is operable in a compact space.
