Title: Evaporation fuel treating device for internal combustion engine
Inventor: ISOBE TAKASHI
IPC: F02M25/08
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To avoid error detection, and improve detecting accuracy by inhibiting detection of leakage when the inner pressure in a fuel tank is changed in the negative pressure direction when a bypass valve is closed, in a device wherein existence of leakage is detected on the basis of change degree of the negative pressure after the fuel tank is made a negative pressure. SOLUTION: In the case where leakage of a tank system is detected, a bypass valve 24 disposed so as to bypass a two direction valve 23 in a charge passage 20 for leading evaporation fuel in a fuel tank 9 to a canister 25 is opened, a mode is transferred to a correcting check mode after a mode is transferred to an atmosphere opening mode for closing a purge control valve 30, and a pressure fluctuation rate per unit time for raising the pressure from the atmosphere pressure to the positive pressure is measured. After the tank inner pressure is decreased to the prescribed pressure, all valves 24, 26, 30 are closed. Subsequently, in a pressure recovering mode, leakage judgment is inhibited in the case where the tank inner pressure is fluctuated from the positive pressure toward the atmosphere pressure.  In the case where the pressure is changed from the negative pressure to the atmosphere pressure, the existence of leakage is judged from a pressure fluctuating rate while leakage is checked.

Title: Automatic transaction processor
Inventor: MATSUISHI TOSHIHARU
IPC: G06Q40/02
Filed: 1986-02-13
Abstract: PURPOSE:To inhibit the operation of a previously fixed transaction mode by continuously counting the frequency of waiting time of a processor which is less than a prescribed time. CONSTITUTION:When the regulation of transaction is to be applied to the processor as the preparation of operation, transactions to be regulated out of various transactions to be processed by the processor are set up on the processor. After starting operation, the existence of a customer can be decided by checking whether a customer has depressed a touch switch on a transaction panel or not as step n24. When 'YES' is obtained at the step n24, transaction processing with the customer is executed and the contents (n) of the transaction number counter are updated. At a busy time, transaction processing is successively executed by customers and the contents of a customer non-detection timer are decided smaller than the prescribed time T, so that the number (n) is increased more and more. When the number (n) exceeds a prescribed value N as the result of decision processing at the step n27, the regulation of the transaction is executed and the previously set transaction is regulated.

Title: Fixing device
Inventor: KOSHIMIZU YOSHIYUKI
IPC: G03G15/00
Filed: 1990-02-09
Abstract: PURPOSE:To prevent an image from being disordered and irregular in glossiness and a recording material from curling by making a nip line linear in a sectional direction of a fixing device and slanting the nip line so that the nip line is lower on an entrance side for the recording material than on an exit side. CONSTITUTION:The recording material P passed through a transfer part advances along an entrance guide 21 and is guided to a nip part. In this case, a heat insulator 53 serves as an entrance guide part 531 for the film to a nip part and as an exit guide part 532. In the sectional direction, the surface of a heating body is linear, and the nip line is therefore linear and slants to the horizontal direction so that the entrance side is lower than the exit side. Consequently, the recording material P is prevented from being tensed to make the rear end curl upward beyond the transfer part and rub an unfixed image; and the separation point between a heat-resisting film 16 and the recording material P is invariably constant, so the image is prevented from becoming irregular in glossiness and the recording material is prevented from curling.

Filed: 1998-02-13
Abstract: PROBLEM TO BE SOLVED: To effectively function a water separator by returning a part of a heating medium liquid to a low temperature liquid tank while pumping the liquid to the separator, and again pumping residual water contents of parts of the tank together with the liquid to the separator. SOLUTION: When pumping of a heating medium liquid 9 is substantially completed so that a flow rate in a drain tube 21 is lowered, a decrease of the flow rate is detected by a flow rate detector 23, the detector 23 is turned OFF, and a solenoid valve 25 is turned ON. Then, the liquid 9 pumped to a water separator 18 is returned to a low temperature liquid tank 8 only at a flow rate for one minute via a return tube 22. At this time, the liquid 9 is diffused in the tank 8 by a diffusing unit 28. Thus, the residual water content of a wall surface, a cooling tube 13 and the like are dropped on a floor of tank 8 together with the liquid 9, gathered in the tube 21, and pumped to the separator 18 together with the residual water content in the tube 21 between the tank 8 and the pump 20 and the liquid 9 returned for the one minute by the pump 20.  Thus, the water content in the tank 8 is all pumped to the separator 18. Thus, the total amount of the mixed water content to the liquid can be removed, thereby improving performance and reliability of the apparatus.
