Patent JP-H0427214-A (JP)
Title: Semiconductor circuit
Inventor: NANBU HIROAKI
IPC: H03K17/56
Filed: 1990-05-23
Abstract: PURPOSE:To constitute the circuit so that a voltage applied to a switch of a TR, etc., becomes smaller than a power supply voltage by an offset voltage portion by inserting a current source between bases of both bipolar type TRs by a circuit for executing the turn-on/turn-off control to a field effect type TR by an input signal. CONSTITUTION:In the case a signal of a high level is inputted to an INPUT, a MOS TR MP is turned off, and a MOS TR MN is turned on. In such a case, since an offset voltage is generated in a PNP bipolar type TR QH and an NPN bipolar type TR QL, a voltage applied to the TR MP becomes smaller than a power supply voltage by an offset voltage portion. Also, in the same way, in the case a signal of a low level is inputted to the INPUT, the TR MP is turned on and the TR MN is turned off, and in such a case, a voltage applied to the TR MN becomes smaller than the power supply voltage by an offset voltage portion of the TR QH and the TR QL. Accordingly, such a problem as reliability of a switch of a field effect TR, etc., drops from a viewpoint of breakdown strength can be solved, necessary input signal amplitude can be made small by an offset voltage portion, and the output signal amplitude becomes large than the input signal amplitude.

Title: Automatic checking device of fire extinguishing equipment
Inventor: FUJIMOTO TAKAFUMI
IPC: A62C37/50
Filed: 1991-05-08
Abstract: PURPOSE:To decrease the load of a CPU in an integral controller, and to quickly cope with the time of such abnormality as the CPU runs away and a fire extinguishing pump does not stop, etc. CONSTITUTION:From an integral controller 200, a turn-on command for designating the upper stage is outputted. A pump control part 100 actuates fire extinguishing pumps 2 for reaching the designated upper stage successively from the lowest stage. Subsequently, from the controller 200, a turn-off command for designating the upper stage is outputted. The control part 100 stops successively the pumps 2 extending from the designated upper stage to the lowest stage. When a CPU 200-1 runs away, an abnormality detection contact 200-6 is opened. As a result, a relay sequence circuit 300 operates, and a turn-off command for all the pumps 2 is outputted. When it is received, the control part 100 cuts the upper stage area which exceeds the upper stage stored before, and validates its turn-off command. Also, the controller 200 monitors a state of the pump 2 through the control part 100, and against the pump 2 whose stop state cannot be confirmed in spite of issuing a turn-off command, it is stopped forcibly through a line group L3.

Filed: 1985-06-19
Abstract: PURPOSE:To contrive inexpensively a higher printing quality, by a method wherein a polyimide film is provided on an insulating substrate at a position corresponding to a heating part, and a resistor layer, an electrode wiring and a protective layer are sequentially provided thereon. CONSTITUTION:The polyimide film 5 trapezoid in cross section is formed on the insulating substrate 1, and the resistor layer 2 having a predetermined film thickness is formed on the substrate 1 and the film 5. Further, the electrode wiring 3 is formed on the resistor layer 2 except the part corresponding to the polyimide film 5, and the protective layer 4 is formed on the wiring 3 and the layer 2. Since the surface of the resistor layer 2 between the wirings 3 is slightly protruded upward from the level of the surfaces of the wirings 3 due to the presence of the polyimide film 5, the surface of the protective layer 4 is protuberant, so that a thermal recording paper can be thereby pressed against the thermal head while exerting a relatively low pressure. In addition, since the polyimide film can be easily patterned and has a favorable heat- accumulating effect, favorable printing quality can be obtained inexpensively.
