Title: One chip microcomputer
Inventor: YANO AKIHIRO
IPC: G06F15/78
Filed: 1989-12-16
Abstract: PURPOSE:To improve the removal efficiency of an initial fault by inputting a signal which is effective only at the time of burn-in to a circuit constituting an instruction changing the value of a program counter in an instruction decoder part. CONSTITUTION:When the voltage of a power source 1 is set to be five volts and 12 volts is impressed on a test terminal B, for example, a P-channel transistor 9 comes to an on-state and an N-channel transistor 10 is in the on-state. Thus, the output of an invertor 8 comes to '0' by setting a transistor size so that the input of the invertor 8 can be recognized as '1' when the P-channel transistor 9 is turned on, and an N-channel transistor 7 comes to an off-state. Namely, an N-channel transistor array 3 and an N-channel transistor 4 come to a detached state and a control signal A is set to be '0' as it is even if the instruction code of FF is inputted from ROM. Consequently, the instruction for changing the value of the program counter is not executed in a burn-in mode. Thus, burn-in is attained in a state where most circuits are operated.

Title: Combustion device
Inventor: UNO KATSUHIKO
IPC: F23D3/18
Filed: 1988-12-23
Abstract: PURPOSE:To reduce an amount of discharged CO by a method wherein unburnt gas is re-introduced in a combustion chamber by means of air fed to a restriction area to burn the unburnt gas, and the unburnt gas diffused to an air introduction passage through a vent hole is oxidized by means of a catalyst body. CONSTITUTION:During high combustion, unburnt gas and air are burnt in a well mixed state with high efficiency in a range of from a position in the vicinity of the upper end of an inner flame cylinder 6 to a position in the vicinity of the upper end part of a combustion chamber 8. The unburnt gas is burnt by means of flame fr formed above the unburnt gas. By reducing an unburnt gas amount through reduction of the exposure height of a wick 1, flame is lowered in the combustion chamber 8. Gasified gas is reduced and an unburnt gas amount is also reduced, a region of mixture with an air flow is lowered downward, and flame fs is formed in the combustion chamber 8. Most of the unburnt gas flowing in a restriction area 22 is fed in the combustion chamber 8 by means of an air flow and burnt by means of the flame fs, but a part of the unburnt gas is diffused through a vent hole 24 to an air introduction passage 25. Since an oxidizing catalyst body 27 is arranged in the introduction passage 25 above the vent hole 24, diffused CO passes through the catalyst body 27 for oxidation, and the oxidized CO rises in the air introduction passage 25, and an amount of CO discharged in the open air is reduced.

Filed: 1990-11-27
Abstract: PURPOSE:To realize driving of power semiconductor elements on high and low potential sides through a single DC power supply by connecting a LED with a CMOS inverter and employing photovoltaic power produced from a photodiode in the driving of the semiconductor element on the high potential side. CONSTITUTION:When control signal on a control signal input terminal 62 has 'Low' level, a P-channel MOSFET 65 is turned ON whereas an N-channel MOSFET 66 is turned OFF thus lighting a LED 63. Consequently, a photocurrent produced in a photodiode array 64 flows through a resistor 68 to produce a photovoltaic power across the resistor 68. The photovoltaic power is then applied between the gate and the source of a power semiconductor element 1a on the high potential side thus turning the power semiconductor element 1a ON. When the control signal has 'High' level, the P-channel MOSFET 65 is turned OFF while the N-channel MOSFET 66 is turned ON thus unlighting the LED 63. At that time, the power semiconductor element on the high potential side is turned OFF.
