Title: Ion exchange method and apparatus for especially regenerating aqueous solution after softening/demineralization
Inventor: GERUHARUTO KAA KUNTSU
IPC: B01J49/00
Filed: 1989-06-22
Abstract: PURPOSE: To regenerate an ion exchanger with a considerably reduced amount of a regenerant and to reduce cost of the regenerant by feeding a regenerant solution into an ion exchange device, as an intermittent pulse flow in the direction opposite to the charging direction. CONSTITUTION: In this process, at the time of regenerating an ion exchanger 2 in an ion exchange device 1 used for softening/demineralizing an aq. solution fed in the charging direction, a regenerant solution 3 is fed into the ion exchange device 1 as an intermittent pulse flow in the direction opposite to the charging direction. More specifically, the regenerant solution 3 is allowed to flow out from a nozzle 11 as an intermittent short pulse flow of certain intermittent pulse intervals, to regenerate the ion exchanger 2 and to discharge the used regenerant solution 3 into a sewer pipe 17, wherein the intermittent pulse flow is effected by using a valve 16 such as motor-operated solenoid valve.  As a result, by using this process, the ion exchanger 2 can be regenerated with a considerably reduced amount of a regenerant and therefore, cost of the regenerant can be reduced, as compared with a conventional process.

Inventor: SAITO CHIAKI
IPC: F02M25/08
Filed: 1989-06-26
Abstract: PURPOSE:To correctly and surely judge anomaly by judging the normalcy/ anomaly of a system on the basis of the booster pressure in an intake passage and the pressure in a purge line when a fuel purge region or the outside of the region is judged. CONSTITUTION:In a fuel purge region which is judged by a judging means B, a judging means A purges the fuel vapor which is adsorbed and caught into a canister into an intake passage, and in a no-fuel purge region, fuel purge is cut off. When fuel purge is executed or when fuel purge is suspended, the judging means A judges normalcy when the relation between the boost pressure inside an intake passage and the purge line pressure which are detected by the detecting means C and D is kept in a prescribed relation, while the judging means A judges anomaly when the prescribed relation is not kept. Thus, anomaly of the fuel purge system is judged correctly and surely, and reliability can be improved.

Filed: 1993-06-30
Abstract: PURPOSE:To obtain an expansion valve having a fast throttling speed and a low operating noise by providing a piezoelectric element and varying the sectional area of a channel of fluid with the displacement of the element as the displacement of a diaphragm. CONSTITUTION:When a pulse voltage is applied to a piezoelectric actuator 30 as a piezoelectric element of an expansion valve 11 and the actuator 30 is longitudinally elongated, an upper end plate 33 is displaced, and the interval D1 between the plate 33 and a partition plate 24 is reduced. The volume of a second operating chamber 35 is reduced, and the operating medium 36 is pressurized by the plate 33. Further, a diaphragm 36 is pressed by the medium 36 to be deformed, and the volume of a first operating chamber 29 is increased. The diaphragm 27 protrudes into a refrigerant flowing space 14, and the interval between the diaphragm 27 and a first refrigerant guide 15 is narrowed. This interval defines the refrigerant flowing area, i.e., the flow rate. Accordingly, the response speed is faster and the operating noise is lower as compared with the case in which a thermal or mechanical transmission mechanism is used to transfer power.

Title: Control system for inter-processor communication
Inventor: AKUTA SHOJIRO
IPC: G06F15/16
Filed: 1985-07-23
Abstract: PURPOSE:To reduce the capacity of a hardware by using an address detector DEC for data and status, and discriminating the data or the status with or without sending a read control line information to input/output device side. CONSTITUTION:An address decoder DEC for data is also used for status. When a processor CPU accesses to an input/output controller IO-1, it gates a gate circuit GT1 by a specified bit information within an address path 1 and designates an designate line 3 controlling the read control line information not to be outputted to a signal line 6. When the data of the input/output controller IO-1 is read, the read control line information of a signal line 5 is passed through the gate circuit GT1 and is outputted to the signal line 6 because the specified bit information is not outputted, and the data of a read buffer register REG1 is sent and is inputted to a two-way bus transceiver TRS. Therefore, the CPU reads the data of the register REG1.

IPC: H04B3/06
Filed: 1979-12-13
Abstract: PURPOSE:To remove interference between codes by adjusting gains of emphasis circuits at an equivalent frequency according to whether output voltage of peak detecting circuits are greater or less than a reference voltage. CONSTITUTION:When interference between codes occurs in the output of adder 5, output levels of peak voltage detecting circuits 71, 72-7N are over or under the reference level. When those output levels are greater than reference voltage Vref, outputs of control circuits 81,82-8N decrease and consequently, gains of emphasis circuits 91, 92-9N are decreased. On the other hand, when output levels of peak voltage detecting circuits 71, 72-7N are less than reference voltage Vref, outputs of control circuits 81, 82-8N increase, and consequently gains of emphasis circuits 91, 92-9N are increased. Such control eliminates the interference between codes by making use of the outputs of emphasis circuits.
