Title: Clock driver circuit
Inventor: TSUTSUMI TOSHIYUKI
IPC: G06F1/06
Filed: 1996-09-13
Abstract: PROBLEM TO BE SOLVED: To judge the cause of LSI malfunction by observing a non-overlapped period detecting signal at a prescribed observing point by an external oscilloscope at the same time of the clock output of a buffer circuit. SOLUTION: Buffer circuits 1 and 2 output clocks CK1 and CK2 to the inputs of CK1A and CK2A, and output to a latch circuit 3, a flip-flop circuit 5 and a NOR circuit 61 by way of observing points TP1 and TP2 at the same time. Then the circuit 61 outputs the NOR signal K of a high level only when both of the clocks CK1 and CK2 are in an inactive period, namely in the period of a low level. In addition, the buffer circuit 62 buffer-amplifies a signal K and outputs the non-overlapped period detecting signal CKN of a sufficiently large driving force to an output terminal. By observing this signal CKN by the external oscilloscope, the phase relation and the pulse width of the clocks CK1 and CK2 at the observing points TP1 and TP2 are estimated to judge whether or not the malfunction of LSI exists in a clock characteristic.

IPC: G06F17/50
Filed: 1994-10-06
Abstract: PURPOSE: To provide the practical trimming device which can obtain a good yield result in a short time and is large in the degree of freedom of trimming. CONSTITUTION: A 1st optimization calculation means 2b extracts a combination of all widths of products meeting calculation conditions from calculation object data inputted from an input means 2a and puts the products together by the widths to find total lengths required for the respective widths. Then a combination of optimum widths whose total length is larger than the total length of the respective widths and minimize a waste of raw materials (or minimize 'waste of raw material + combination of widths × weight') is found and only a combination of widths whose length is larger than 0 is employed.  A 2nd optimization calculation means 2c finds what product with what width needs to be allocated to manufacture more than a necessary number of products and minimize the waste of raw materials as to the combination of respective widths found by the 1st optimization calculation means 2b, and allocates products to the respective widths to obtain a trimming pattern 3.

Filed: 1988-09-27
Abstract: PURPOSE:To attain a high speed switching by connecting a capacitor in parallel with the 1st resistor connecting to a cathode of the 1st light emitting diode and connecting a photodiode receiving an optical signal of the 2nd light emitting diode in parallel with a photodiode array in an opposite polarity. CONSTITUTION:A capacitor 4 is equivalent to the short-circuit state at the leading of an input signal pulse, a large current flows to the 1st light emitting diode 1, and an optical current generated by a photodiode array 6 coupled optically with the light emitting diode 1 is also increased. Thus, a gate capacitance of an output MOSFET 8 is charged rapidly and the output MOSFET 8 is rapidly turned on. Since the electric charge charged in the capacitor 4 is discharged through the 2nd light emitting diode 5, the light emitting diode 5 is lighted, an optical electromotive force is generated in the photodiode 7 coupled optically with the light emitting diode 6 to assist the discharge of the electric charge charged in the output MOSFET 8. Thus, the output MOSFET 8 is turned off at a high speed.

Filed: 1995-09-22
Abstract: PROBLEM TO BE SOLVED: To control a fluid temperature at the outlet port of an evaporating tube in a furnace within the optimum range by controlling the amount of spray water for a superheat reducer based on the temperature difference of the superheat reducer. SOLUTION: The difference of superheat reducer temperature differences between single fuel combustions is obtained by a subrractor 4. On the other hand, the correcting coefficient of the difference of superheat reducer temperature differences is obtained by a third function converter 5 from the mixed firing rate of different kind fuels A, B. The correcting coefficient is multiplied by the difference of superheat reducer temperatures by a multiplier 6 to obtain a bias amount with respect to the reference value of superheat reducer temperature differences and add it on the refereence value in an adder 7 whereby the objective value of superheat reducer temperature differences upon mixed firing is obtained. The amount of spray water for the superheat reducer is adjusted based on the objective value of superheat reducer temperature differences.  The objective values of temperatures before or after the superheat reducer can be changed in accordance with all mixed firing rate whereby fluid temperature at the outlet port of evaporating pipe of furnace can be controlled within the optimum range. On the other hand, separate facilities, employed conventionally, can be omitted whereby cost is reduced.

Title: Electrochromic element
Inventor: UCHIKAWA KIYOSHI
IPC: G02F1/155
Filed: 1984-11-21
Abstract: PURPOSE:To obtain an electrochromic element which vanishes perfectly color and has superior durability by forming a two-layered counter electrode consisting of a layer contg. Ir, Ir oxide or hydroxide dispersed as a dispersoid in a transparent, electrically conductive and solid dispersion medium and of a transparent and electrically conductive layer and by specifying a cation feeding source. CONSTITUTION:A transparent and electrically conductive layer D2 is formed on a glass substrate, and a transparent dispersed layer D1 consisting of Ir2O3 as a dispersoid D11 and SnO2 as a dispersion medium D12 is formed on the layer D1 by the high frequency ion plating of a metallic Sn and Ir in an O2 atmosphere. A transparent and ionic conductive layer C is formed on the layer D1 by the vapor depsotion of Ta2O5 in the presence of O2. A transparent, amorphous and electrochromic (EC) layer B of WO3 or the like is formed on the layer C, and an opaque electrode layer A of Al, Ni or the like is formed on the layer B to obtain an EC element. Since the layer C conducts H<+> and OH<-> and does not conduct electron, color developed in the layer B is retained even when the application of voltage is stopped, and a memory effect is produced. The color is vanished by applying voltage opposite to the voltage for color development and equal to it in level. The resulting EC element has superior durability even at high temp. and gives a high-contrast display.
