Patent JP-S56166772-A (JP)
Title: Ac/dc converter
Inventor: KANEDA ISAO
IPC: H02M7/12
Filed: 1980-05-26
Abstract: PURPOSE:To remove the ripple components caused by a commercial low frequency power source by applying a negative bias to the second inductor. CONSTITUTION:When a low frequency power source 1 is thrown, an oscillation capacitor 7 is charged through the first inductor 6 and a negative bias coil 81. When the charged voltage of the capacitor becomes higher than the predetermined value, an oscillation occurs via the coil 81, the second inductor 8, a thyristor 9, and an oscillation capacitor 7, and the bias of the coil 81 is suitably regulated. Thus, the oscillation output voltage b from which ripple components caused by the low frequency power source are removed with constant peak value can be obtained from the first inductor 6.

IPC: F02D21/08
Filed: 1986-03-31
Abstract: PURPOSE:To control an EGR quantity and a supercharge pressure accurately by leading a supply air pressure and a pressure in the upstream of EGR regulation valve to a waste gate valve while switching in accordance with the vehicle speed such that when the upstream pressure is led in, the supply air pressure is led to EFR regulation valve so as to close the EGR regulation valve. CONSTITUTION:A waster gate valve 66 arranged in a bypath 62 for a turbine 16 of a supercharger 4 is driven by an actuator 68 to which the pressure supply is switched by a changeover valve 80 between a first pressure conduit 82 for leading in the pressure from an air supply path and a second pressure conduit 84 for leading in the upstream pressure of a regulation valve 22 arranged in an EGR path 20.

Title: Present position storing method for controller
Inventor: ONISHI MASAYASU
IPC: G05D3/00
Filed: 1987-03-24
Abstract: PURPOSE:To store the data on the present position of a movable part, by reading twice the number of pulses into a CPU at a prescribed timing interval and defining a first number of pulses as the present position of the movable part when a second number of pulses is reset at '0' by a resetting signal. CONSTITUTION:The number of pulses counted by a counter 5 is read twice into a CPU 6 at a prescribed timing interval. The second number of pulses is usually defined as the present position of a movable part. However, the first number of pulses is defined as the present position of the movable part in case the second number of pulses is reset at '0' by a resetting signal. Thus, it is possible to store the number of pulses set right before this number is set at '0' into a memory 10 even though the number of pulses counted by the counter 5 is reset at '0' before data are sent to the memory 10 by a resetting signal which is outputted by the drop of the power supply voltage.

Patent JP-S56166475-A (JP)
Title: Period detector
Inventor: YAMAMOTO HIDEKI
IPC: G01R23/10
Filed: 1980-05-27
Abstract: PURPOSE:To make it possible to visually confirm the pulse spacing of the pulse being measured, at will, by properly connecting a pulse processing circuit to a period detector through a switch or the like, and extending the display time. CONSTITUTION:With a switch 22 kept ON, the output of a pulse processing circuit 21 becomes L, while the output of an NOT circuit 16 becomes H, and the pulse to be measured is inputted to the reset input terminal R of a counting circuit 18 through a differentiating circuit 13 and an AND circuit 15. On the other hand, the reference pulse from a reference pulse generating circuit 11 is applied to an input terminal C through an AND circuit 14 in order to detect the pulse spacing of the pulse being measured. When the switch 22 is turned OFF, a D type FF21a is set by  the differentiated output b, and the output of the processing circuit 21 is H until the  output of the CR time-constant circuits 21b, 21c and 21d becomes lower than the threshold voltage. Thereby, it is possible to obtain an output of time width sufficient to drive the display part. In addition, it becomes unnecessary to stop the detecting function when display is being performed.

Title: Information processor
Inventor: KOYANAGI HISAO
IPC: G06F9/46
Filed: 1989-03-23
Abstract: PURPOSE:To control even an irregular busy state at a function unit side without deteriorating the performance by applying holding to a counter by a busy signal of the function unit. CONSTITUTION:A request issue requesting part 1 sends a request issue request to a request generating part 2, and the request generating part 2 sends out a request signal to a cache control part 4 and a request control part 3. The request control part 3 analyzes a kind of its request and presets a prescribed value to a counter. Until this preset value becomes a value determined in advance, the count processing is executed at every one cycle, and it is not permitted to issue the next request until the contents of this counter reach a specific value. Also, in response to the generation of a busy signal for inhibiting an issue of a request, the count processing is inhibited and its contents are set to a holding state, and when the busy signal is ended, the holding state is released. In such a way, even against an irregular busy state generated in a function unit side, an access issue control can be executed without deteriorating the performance.
