摘要： PROBLEM TO BE SOLVED: To provide a power supply system capable of consistently and efficiently supplying the power to a load device having an instantaneous load fluctuation and an intermittent no-load state while being free from any effect of the voltage drop caused by the instantaneous load fluctuation.
SOLUTION: Fluctuating loads 60, 61 having instantaneous fluctuation and intermittent no-load state are included in a plurality of loads 9, 60, 61. A bus bar comprises an AC bus bar 5 for supplying the AC power generated by a part of generators 22, 23 to an inverter 7, and another bus bar 44 for supplying the AC power generated by other generators 20, 21 to the fluctuating loads 60, 61; and further comprises switches 2, 3 for connecting the outputs of the generators 20, 21 connected to the other bus bar to the AC bus bar 5. When the instantaneous fluctuation of the fluctuating loads 60, 61 is continuously repeated, the switches 2, 3 are in an open state. When the fluctuating loads are continuously in a non-load state, the switches 2, 3 are in a short-circuit state.

摘要： PROBLEM TO BE SOLVED: To boost the information processing unit in a state before rewrite when the information processing unit is restarted even when a power failure or the like takes place during rewrite of an operating system in a flash memory. SOLUTION: A CPU 108 copies an operating system stored in a flash memory 106 to an idle area of a flash memory 105. The copying of the operating system is stored in a storage circuit 104 and an information storage circuit 1012 backed up by a battery. While the information of representing the copying as above is stored in the information storage circuit 1012, an access conversion circuit 1011 of a bridge circuit 101 converts a read request stored in the flash memory 106 of the CPU 108 into a read request of the operating system copied in the flash memory 105. The CPU 108 rewrites the operating system stored in the flash memory 106, based on rewrite information of the operating system read out of an FDD 103.

摘要： PURPOSE: To continue transmission of data by using the dummy data, etc., in place of lost data in order to make a receiver device act as if the lost data were still available. CONSTITUTION: When the data are lost on a general purpose data transmission line 3, a data reception confirming part 27 finds the loss of data by a date serial number and informs a dummy data generation part 26 of this fact. The part 26 generates the dummy data and supplies them to a selector 25. Then the part 27 controls the selector 25 for selection of the dummy data, and a driver 22 sends the dummy data to a public network 1. Thus the dummy data are received with the reception timing of a frame flag and therefore the data to be interpolated are generated at the receiver side from the timing information and a framing protocol. Then the receiver side acts as if the frame flag were received.

摘要： PURPOSE:To obtain a configuration control circuit capable of optionally defining an initial operation mode, changing the operation mode at optional timing and allowed to be used also as an initial operation setting circuit and an operation mode setting register. CONSTITUTION:At the time of turning on a power supply for a device, this configuration control circuit 2 outputs mode setting data 5 and sets up the operation mode of a logical circuit 6 in an LSI 1. Since the control circuit 2 can change the operation mode by software after starting the device, the circuit 2 changes the operation mode of the circuit 6 by a register writing command 12 outputted from a register writing command generating circuit 11 by signals outputted from a CPU 7 to a data bus 8 and an address bus 9 and a status signal 10. Namely the control circuit 2 is functioned also as a register for changing the operation mode of the logical circuit 6 by the software.

摘要： PURPOSE:To read out data of plural kinds of font memories by shifting the data by arbitrary bit numbers in accordance with the data of each memory by sharing the same shifter when the plural kinds of font memories are used. CONSTITUTION:Font data stored in three font memories of 24 bits 10, 16 bits 11, and 8 bits 12 are supplied to a switch 2 which is a switching means respectively through font data buses 100-102 and the switch 2 switches the font data to be sent to a shifter 3 in accordance with the preset instruction of a control section 4. The shifting quantity of the font data is previously set by means of a microprocessor and the font data sent to the shifter 3 are shifted by an arbitrary bit number based on a control signal produced from information of the shifting quantity, etc., given to the control section 4. Therefore, the font data shifted to an aimed bit position are outputted as the output 104 of the shifter 3. As a result, data are read out to a data bus 105.

摘要： PURPOSE:To prevent the titled electric circuit from causing a detouring circuit by a method wherein the circuit constituted so that an opening and closing switch for a compressor will never be closed during ventilating operation. CONSTITUTION:An opening and closing switch 3 for a compressor is provided between a temperature regulator 5 and a compressor protecting unit 6 in case an electric source is single phase while the same switch 3 is provided between the temperature regulator 5 and an electromagnetic switch 14 in case the electric source is three phase. Thus, the opening and closing switch 3 for the compressor is being opened during ventilating operating to preclude the condition of the compressor 7 whereby the generation of a detouring circuit may be prevented.

摘要： PURPOSE:To design a smaller model of water pump and also to design flexibility for installation augmentation of electronic unit by separating the cooling water passage running in a water cooler from the cooling water passage running in an electronic unit. CONSTITUTION:A cooling water passage going from a water pump 2 and coming back to the water pump 2 through a water cooler 3, and a flow rate adjusting valve 23 is formed and it is made a water cooling system 21 and further, a cooling water passage going from the pump 2 and coming back to the pump 2 through a heat exchanger 6 in an electronic unit 5 is formed and this water passage is installed in parallel to the water passage of the water cooling system 21. With this structure, the water heat loss DELTAPH of the water cooler 3 becomes equal to that of the heat exchanger 6 and then, the flow rate W of the water pump 2 becomes smaller than that of the conventional one as a characteristic 17 shown in a figure, thus, a pump can be made smaller. And further, even if the installation of the electronic system 5 is augmented, flow rate to the water cooling system is constant, as a result, exchange of the water pump 2 is not required.
