Title: Oxygen concentration detector for combustion machine
Inventor: KASADA TOSHIO
IPC: G01N27/62
Filed: 1984-10-11
Abstract: PURPOSE:To decrease the error in measuring oxygen concn. and to prevent the false announcement of warning for lack of oxygen, etc. by providing a means for changing over the rate of combustion, changing over forcibly an ion current value to the preset rate of combustion, executing combustion and measuring the oxygen concn. after lapse of the specified time. CONSTITUTION:The means 11 for changing over the rate of combustion consisting of, for example, an electromagnetic pump and an oscillation circuit for controlling the operating speed thereof, etc. is connected to a microcomputer 10 of a detector. The ion current flows when a flame is formed between a burner head 3 and a flame rod 1 by operating an ignition switch. The ion current is converted to a voltage signal A by a resistor 6 and said signal is passed through a protective resistor 7 and is thus made to the voltage signal B which is inputted to the microcomputer 10. The microcomputer 10 counts the time from the start of the combustion upon receipt of the input signal C and feeds the signal E to the means 11 after the prescribed time to increase the rate of combustion to strong combustion for the specified period. The ion current to be used as a reference is measured upon lapse of the prescribed time and is stored in a storage device. The exact detection of the oxygen concn. is thus made possible.

Title: Power source wiring for ternary output driver
Inventor: OGAWA TOSHIYUKI
IPC: H03K17/16
Filed: 1988-08-26
Abstract: PURPOSE:To reduce a leakage current even when the output of an output driver becomes higher in impedance condition by separating a power source and a ground at the output driver side of a ternary output driver from the power source and the ground of other circuit part. CONSTITUTION:The potential of grounds VSS2 and VSS3 before and after the potential of a ground VSS1 of an output final step is wired independently from others. These 3 potentials are connected and kept at the same potential. By such constitution, the low level of signals N1 and N2 when the output of an output driver 4 holds a high impedance and a ground VSS1 are the same potential, and isolated from a ground VSS4 of other circuit 5, then the potential difference does not occur between the gate sources of the MOS transistors Q1 and Q2. Thus, the output of the output driver 4 holds the high impedance and even then, the generation of the leakage current is suppressed.

Filed: 1988-08-30
Abstract: PURPOSE:To prevent a motor from damaging by supplying a predetermined signal in response to the control mode of the motor to drive the motor, and controlling a motor current when the excess of the current is detected to stop/ reversely rotate the motor. CONSTITUTION:A motor driver 3 is controlled by a signal responsive to a control mode output from a controller 5 to rotate a motor 2 in response to a motor. When a current detector 4 detects the excess of a motor current, it supplies an overload signal to the controller 5 to stop the motor or to reversely rotate. Thus, the motor is stopped or reversely rotated not only when an overload occurs due to the malfunction of the motor itself but when a finger is inserted to the movable unit of the motor, thereby preventing a danger. This is adapted for a video tape recorder and the like.
