Title: Fuel injecting rate control device for vehicle
Inventor: ISHIDA KATSUMI
IPC: F02D41/04
Filed: 1988-12-28
Abstract: PURPOSE:To reduce deviation in both high and low injecting rate ranges by carrying out an addition correction of a control characteristic using adjusting rate of an adjusting point in a low injecting rate range inputted by a manual operation, and a multiplication correction using the adjusting rate of the adjusting point in a high injection rate range. CONSTITUTION:With regard to an adjustment rate adjusted by a first adjuster 11 for correcting the control characteristic of a fuel injecting rate at one adjusting point in a low injecting rate range, an additional correcting rate Ka is calculated from a data table in the ROM 18 of a control circuit 4. On the other hand, an adjustment rate adjusted by a second adjuster 12 for correcting a control characteristic at one adjusting point in a high injecting rate range is calculated as a multiplication correcting rate. Then, a basic fuel injecting rate calculated on the basis of an engine rotational speed and intake pipe pressure coused by sensors 2, 3, is processed by using the addition correcting rate and the multiplication correcting rate, thus a fuel injecting rate is found out so as to drive a fuel injecting valve 6 on the basis thereof. It is thus possible to correct the control characteristic forward coveregence of a deviation certainly to 0 without dispersing the deviation between a real rule injecting rate and the design fuel injecting rate.

Title: Dynamic random access memory device
Inventor: SUWA MASATO
IPC: G11C11/404
Filed: 1988-12-28
Abstract: PURPOSE:To realize the complete aging by applying alternately two types of high voltage of the directions opposite to each other to an area between two electrodes of a capacitor means at a memory cell via a selection means. CONSTITUTION:The high voltage detectors 30 and 40 receive the selection signals phi1 and phi2 from outside to select a 1st high voltage VCC or a 2nd high voltage VSS. A switch means 80 selects the high voltage that is applied to a capacitor means 5 in a memory cell 8 via a high voltage application means 71 in response to the signals phi1 and phi2. Thus both voltages VCC and VSS of the directions opposite to each other are applied to the electrodes 5a and 5b of a capacitor means 5 in the cell 8 in response to the signals phi1 and phi3. Therefore the voltages VCC and VSS are alternately applied to an insulator 5c of the means 5. Thus the insulating performance of the insulator 5c is accurately confirmed. As a result, the aging time is shortened.

Filed: 1989-12-21
Abstract: PURPOSE:To prevent warpage and/or swelling by a method wherein one end of the thick member of the outer peripheral surface or the inner peripheral surface of an elastic body, generating a traveling wave on the driving surface thereof, is formed in the same plane as the connecting surface or the driving surface of the elastic body. CONSTITUTION:When an AC voltage (driving signal) is impressed on a piezo-electric body 1b, bending vibration is generated in the piezo-electric body 1b and a traveling vibration wave is generated in the driving surface of the elastic body 1a whereby a rotor 2 is driven. In this case, the amplitude of the vibration wave, applied on a supporting member 30 and the elastic body 1a, is substantially zero since the thick-walled part 32 of the supporting member is fixed at the connecting part between a diaphragm 31 and the thick-walled part 32 whereby the amplitude of the diaphragm 31 is increased as the diaphragm 31 approaches the elastic body 1a. In this case, the supporting member 30 is formed integrally with the elastic body 1a and, therefore, the supporting member 30 will never be separated from the elastic body 1a.

Title: Ice making device of refrigerator
Inventor: NAKANISHI KEIJI
IPC: F25C1/10
Filed: 1991-12-17
Abstract: PURPOSE:To prevent an excessive lowering of temperature even under a condition in which an ice making pan is exposed to cold air for a long period of time while the ice making operation is completed. CONSTITUTION:Ice making operation is carried out by heating the upper part of an ice making pan 12 by a heater 22 while the lower part of the ice making pan 12 is being applied with cold air. As an ice making pan temperature sensor 19 detects a temperature of -13.5 deg.C or less, ice making operation is completed. Since this ice making completion process requires a period more than a specified period of time, ice separation is not carried for a sake of safety even if the temperature sensor 19 detects a temperature of -13.5 deg.C or less. With such an arrangement, during a rapid cooling operation, a large amount of cold air than that of the normal operation is blown against the ice making pan 12, the ice making pan temperature sensor 19 detects early -13.5 deg.C and then an ice separation waiting state is attained until a specified period of time elapses. However, under this ice separation waiting state, the heater 22 is electrically energized to heat the ice making pan 12, so that the ice making pan 12 is not excessively lowered in its temperature.
