Title: Electronic ballast for discharge lamp
Inventor: SEKINE MASAOKI
IPC: H05B41/24
Filed: 1995-04-14
Abstract: PURPOSE: To maintain lighting even in the case where an input power source is momentarily cut off during lighting by providing an input current control means for increasing the input current to a bridge invertor circuit when an input voltage detecting means detects the lowering of the input voltage. CONSTITUTION: In the case where the input voltage of an electronic ballast of a discharge lamp is momentarily cut off, when the input voltage of a bridge invertor circuit 13 is lowered than that of the normal time, the output voltage of a computing amplifier OA is lowered, and the pulse width of the output signal of a comparator CO1 is widened. Next, a control circuit 17 widens the time ratio of the bridge invertor circuit 13 in response to the output of the comparator CO1, and enlarges the input current to the bridge invertor circuit 13 till the voltage of the non-inverted input terminal of the computing amplifier OA becomes equal to the voltage of the inverted input terminal.  When the input voltage of the circuit 13 is lowered, the current reference signal is raised in response to the reduction of the input voltage, and the constant power can be thereby supplied to a discharge lamp LA. Consequently, even in the case where the alternating current input voltage is momentarily cut and the input voltage of the circuit 13 is lowered, the constant power can be supplied to a high luminance discharge lamp.

Title: Hot and cold water mixing controller
Inventor: UEKI KOICHI
IPC: F24D17/00
Filed: 1988-05-11
Abstract: PURPOSE:To prevent the generation of a sudden hot water temperature fluctuation when low temperature hot water has all flowed out by driving immediately a mixing means to an optimum valve position by a larger energizing quantity than that of a stationary time, when a sudden variation of an outflow hot water temperature has been detected. CONSTITUTION:When low temperature hot water in a hot water side piping 3 which has been connected to a mixing means 11 all flows out and hot water of an original supply hot water temperature starts to be supplied to the mixing means 11, an outflow hot water temperature starts to become high suddenly. When this hot water temperature variation is detected by a dead water completion detecting means 19, said means is switched to a control rule storage means 22 through a switching means 24. A first control rule and a temperature deviation are inferred by a control inferring means 21 and outputted to the mixing means 11, and the mixing means 11 is driven by a larger energizing quantity than an energizing quantity of a stationary time. In such a way, even in case of a sudden hot water temperature variation, by mixing means 11 is driven to the vicinity of an optimum valve position, and also, by a larger energizing quantity than usual, therefore, it can reach quickly the optimum valve position, and a large overshoot is generated in an outflow hot water temperature.

Title: Encoding method of picture transmission
Inventor: IGAWA KAZUHIKO
IPC: H04N1/417
Filed: 1982-06-30
Abstract: PURPOSE:To meet requirements of the code system of the GIII standard and to improve a picture transmission speed by performing the one-dimensional encoding of a picture signal of white line of main scanning line of a transmit original and performing the two-dimensional encoding of picture signal of other main scanning line. CONSTITUTION:An original read part 1 makes a scan on the transmit original to generate a binary picture signal DA corresponding to pieces of black-and- white information on picture element, and inputs them to a data processing part 2 together with a transfer clock signal CKt. The output DQ of a JK flip- flop 3 is L when a scanning line is a white line or H when there is a black picture element. The data processing part 2 performs the one-dimensional encoding when the DQ is L to add a dummy bit. When the DQ is H, on the other hand, the one-dimensional encoding is carried out to denote the value obtained by subtracting ''1'' from a K parameter by an MR encoding system as I, setting the number of main scanning lines to be encoded in two-dimensions by I. Every time one line is processed, ''1'' is subtracted from I and the processing is carried out until I becomes zero or until the DQ goes down to L; and a return to the initial state is made when the I becomes zero.
