Title: Magnetic tape test system
Inventor: ISAKA KAZUO
IPC: G11B5/84
Filed: 1986-01-22
Abstract: PURPOSE:To simplify the quality check of a magnetic tape by detecting/counting the number of blocks to be written and causing errors and classifying the quality of a magnetic tape from the result of counting. CONSTITUTION:A write instruction is given to a logic 45 from a microprocessor 41 of a magnetic tape controller, the logic 45 generates write data and the data is written on a tape by a write head 38 through a logic 47 and a logic 34 of a magnetic tape device. Then data read by a read head 39 is inputted to the logic 45 through the circuits 37, 44. When the logic 45 receives the data, the block and error are detected and the resulting signal is transferred to the processor 41 through a selector 43. The processor 41 counts each numeral, the quality of the magnetic tape is decided by the count result and the display data is transferred to the display panel 32 via a microprocessor 30 based on the decided result to display the result of quality of the tape.

Abstract: PURPOSE:To clamp a reference voltage accurately by adding an offset correction transistor(TR) and a constant current source to an input clamp circuit and making the collector current of TRs being components of a differential amplifier identical to each other thereby suppressing the generation of an offset voltage. CONSTITUTION:A switch circuit 9 is turned on in the clamping timing, a voltage generated in a reference voltage source 8 is fed to differential NPN TRs 4, 5 being components of a differential amplifier 20 and active load PNP TRs 1, 2 and given to a clamp input terminal 3 to clamp the input signal. In this case, an offset correction TR 10 is made to the same structure as the TRs 1, 2, the size is doubled, the current of correction constant current sources 11, 7 is made identical to make the current of the differential TRs 4, 5 identical to each other. Thus, the generation of the offset voltage due to the current unbalance is suppressed and the reference voltage is sent accurately to a clamp input terminal 3.

The valve 19 rapidly sets the pressure difference between the tubes 7 and 9 connected to the compressor 1 to zero by fully opening the valve when the compressor 1 is stopped. Further, the valve 19 can be optimally regulated at the pressure difference between the discharge side and the suction side of the compressor 1 under the control of the valve opening by the pressures detected by the sensors 21, 22.

Title: Self-ignition timing control method for engine of premix compression self-ignition type
Inventor: NAKAMURA YUJI
IPC: F02D19/02
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To make self-ignition timing proper thereby to obtain a good driving state, by mixing exhaust gas emitted from an engine to charging air and controlling a temperature of such charging air. SOLUTION: In a control apparatus 12, actual self-ignition timing information in one operating cycle of an engine 100 is input, and a memory means 120 is provided inside the control apparatus 12. The memory means 120 stores timing information on timing where compression self-ignition should occur according to a driving condition. Actual self-ignition timing and preferred self- ignition timing is compared to determine whether the actual self-ignition timing is delayed or advanced. When the actual self-ignition timing is delayed, opening of a three-way valve 14 is controlled to increase returned exhaust gas amount and thereby to lead a charging air temperature to a side for increasing a present state.  When the actual self-timing is delayed, the opening of the three-way valve 14 is controlled to decrease the returned exhaust gas amount and thereby to lead the charging air temperature to a side for decreasing the present state. By the control as described above, self-ignition timing is kept to be in a preferable state.

Title: Electrical water heater
Inventor: ISHII KATSUMI
IPC: F24H1/20
Filed: 1983-01-28
Abstract: PURPOSE:To perform an effective water heating operation meeting the actual requirement for use of hot water by a method wherein a daytime power heater is energized after a suitable quantity of hot water supplied from a hot water storage tank is used so that the supply of electricity to the heater by frequent switching operations is prevented and the overheating of the heater due to the supply of daytime power is prevented. CONSTITUTION:When water is heated by a midnight power heater, a thermostat 7 always goes off earlier than a thermostat 6 despite that the temperature of the thermostat 6 is higher than that of the thermostat 7 because the set temperature of the thermostat 7 is made lower than that of the thermostat 6. Accordingly, when the supply of midnight power is stopped (usually at A.M. 7), daytime power is supplied to the daytime power heater so that the temperature of water in the hot water storage tank 1 is not overheated and the consumption of the expensive daytime power is controlled to thereby secure economy and safety. Further, when the hot water is supplied through a hot water supply pipe 3 and low temperature city water is supplied from a water pipe 2 so that the temperature in the lower part of the hot water storage tank 1 lowers to operate the thermostat 6, the thermostat 7 does not operate until after a suitable quantity of the hot water is used since the thermostat 7 is provided at a position higher than the thermostat 6 and therefore, it is not necessary to operate the daytime power heater frequently everytime when the hot water is supplied.
