Filed: 1986-05-13
Abstract: PURPOSE:To improve a performance in operation of a heat exchanger having longitudinal buffles and eliminate a replacement of damaged seal plate at a periodical service by a method wherein a seal plate made of shape memory alloy is applied to close a clearance between the longitudinal buffle of the heat exchanger and a shell. CONSTITUTION:To a longitudinal buffle 2 of a heat exchanger is fixed a seal plate made of shape memory alloy 1 with bolt etc. When a bundle of pipes 4 is to be inserted into a shell 3, either a predeformation or a contact with the shell 3 during the insertion etc. causes a seal plate 1' to be bent. After the bundle of pipes 4 is fixed to the shell 3, it is heated up to such a temperature that permits the memory to be restored with steam or the like, resulting in that the shell plate 1'' is returned to its original shape to abut against the shell 3. With this abutment, the upper and lower portions of the longitudinal buffle 2 are sealed. When the bundle of pipes is to be inserted, even if the seal plate is deformed, it is heated with steam or the like to cause it to be closely contacted with the shell and a superior sealing characteristic is provided. Even in the case of a heat exchanger of a low temperature operation, it is sufficient to heat the pipes before starting operation.

Title: Diagnostic apparatus for vaporized fuel disposal equipment
Inventor: KAWAMURA KATSUHIKO
IPC: F02M25/08
Filed: 1998-04-17
Abstract: PROBLEM TO BE SOLVED: To enable leakage diagnosis even before starting air fuel ratio feedback control, and eliminate turbulence in an air fuel ratio caused by the leakage diagnosis. SOLUTION: In this apparatus, vaporized fuel generated in a fuel tank 41 is introduced via a first passage 43 to a canister 42. A second passage 46 communicates the canister 42 with a intake pipe 45 locked in the downstream of a throttle valve 44. A purge control valve 47 opens and closes the second passage 46. A drain cutting valve 48 opens and closes the air release port 42a of the canister 42. A holding means 49 totally closes the purge control valve 47 and the drain cutting valve 48 in shutting down an engine. Thus a passage from the fuel tank 41 to the purge control valve 47 is retained under a closed space. A leakage diagnostic means 51 executes leakage diagnosis based on a decrease in passage pressure after the retention caused by a condensed vaporized fuel in the closed passage in starting the engine.

Abstract: PROBLEM TO BE SOLVED: To enable a non-contact area to be easily and efficiently formed between laminated sheet layers by using a roll with the peripheral surface around which at least, a single circuit of groove is made as a nip roll when a thermoplastic synthetic resin is laminated on the surface of a base material by extruded lamination process. SOLUTION: When laminating a thermoplastic synthetic resin on the surface of a base material by extruded lamination or sandwich lamination process, a nip roll 1 with a groove 2 making a single circuit around the peripheral face of a roll surface 3 is used. Consequently, when attaching the thermoplastic synthetic resin on a base material layer under pressure, the area of a laminated sheet positioned at the part of the groove 2 is set to a non-contact state at least, between the base material layer on the nip roll side and the adjacent resin layer. In addition, the laminated sheet is cut to an appropriate size in an orthogonal direction with the flowing direction in which a manufactured laminated sheet has a continuous non-contact area. By so doing, it is possible to manufacture the flat laminated sheet with the non-contact area at a specified identical position.
