Title: Power supply switching circuit
Inventor: SHIRAISHI HIDEKI
IPC: H02J1/00
Filed: 1979-06-15
Abstract: PURPOSE:To prevent the production of noise at power supply switching, by connecting the time constant circuit to the base of two swtiching transistors TR. CONSTITUTION:The time constant circuit consisting of resistance 10, capacitor C9, resistances 6, 7 and C12 is connected to the base of the switching transistors TR2, 3. Further, when the switch SW8 is OFF, the voltage of the power supply 1 is fed to the base of TR2, 3, causing TR2 ON and TR3 OFF, and the reception circuit 4 is operated and the transmission circuit 5 is inactive. In this case, specified charges are stored in C9 and C12. With this state, when SW8 is OFF, the charge of C9 is immediately discharged via the diode 11, but since the charge of C12 is gradually discharged via the resistance 7, and TR3 is ON after a given time after TR2 is OFF, and the electromagnetic waves produced from the circuit 5 do not enter the circuit 4, to prevent the production of noise.

Title: Vehicle control device
Inventor: SHIOYAMA GIICHI
IPC: F02D29/02
Filed: 1988-03-31
Abstract: PURPOSE:To appropriately control a vehicle by compulsorily restraining the output power of an internal combustion engine when various voltages show such that a constant speed running device operates even though the vehicle speed is below a predetermined value. CONSTITUTION:A constant speed running device 100 feed-back controls the opening degree of a throttle valve in an internal combustion engine 107 so as to make the actual speed of a vehicle coincident with a desired speed, and accordingly, the vehicle runs at the desired speed, automatically and constantly. In this arrangement, there are monitored a power source voltage 103 applied to a control unit 101 in the constant speed running device 100, and a control voltage 104 applied to an actuator control section 102. When the vehicle speed detected by a detecting means 104 is below a predetermined value, if the power source voltage 103 or the control voltage 104 is detected, a control means 106 restrains the output power of the internal combustion engine 107. Thereby it is possible to suitably control the vehicle.

     CONSTITUTION: The moisture of the sludge 10 on the filter cloth 1 being traveled is sucked into the vacuum chamber 6 and is discharged from the drain pipe 7. Thus partly dehydrated sludge 10 is moved into the space being pinched by the filter cloth 1 and the air bag type pusher 13 cylindrically constituted of the flexible air tight material like as the rubber, etc.; and then, the sludge 10 is compressed by the pusher 13 in order to improve the dehydration efficiency. The surface of the pusher 13 deforms with the distribution of the thickness of the sludge 10, so that the sludge 10 is pressed uniformly over the whole surface. The dehydrated cake 10a passed above dehydration zone due to the pusher 13 is raked out of the filter cloth 1 by the raking plate 11. After that, the residual sludge sticking on the filter cloth 1 is washed away by water jetted from the washing nozzle 12 in order to prevent the clogging at next dehydration pass.

Abstract: PURPOSE: To reduce the input errors of a dial number directly inputted by ten keys by reporting that effect to an operator when the stored dial number in the past similar to the newly inputted dial number is found by a dial number comparison means. CONSTITUTION: Whether or not it is the direct input by the specified ten keys of an opposite party is judged, and in the case of the direct input by the ten keys, the inputted dial number is stored in the prescribed area of a RAM 4.

Title: Relational data base synchronizing method and recording medium for recording program for the same
Inventor: KODAMA MICHITERU
IPC: G06F17/30
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To make master data synchronized with data of a replica machine which are normally updated in isolation from a master machine, without contradiction in a relational data base synchronizing method. SOLUTION: After a replica machine 4 is connected to a master machine 1 through a network 3 at an arbitrary time, and a new record of the last update date is extracted as a replica difference from a replica data 5 based on a master difference extraction completion time. In the master machine 1, a replica difference reflection time extracts the record newer than the master difference extraction completion time from master data 2, updates a master difference extraction completion time to the current time, and reflects the replica difference upon the master data 2, while the replica machine 4 reflects the master difference upon the replica data 5 and updates the master difference extraction completion time. Thus, synchronous processing is completed and connection to the master machine 1 can be disconnected at an arbitrary time.

Filed: 1978-06-27
Abstract: PURPOSE: To shorten starting time until a pump reaches a pumping-up condition after receiving starting instructions, by starting a runner in water, by aerially racing the runner when it reaches some speed of revolution and by pumping-up operating the pump when the runner reaches synchronous speed.
