IPC: H02M7/48
Filed: 1994-09-30
Abstract: PURPOSE: To prevents backflow of a current or a transient current by setting an inverter output voltage equal to or several volts higher than the commercial system voltage when linking the commercial system power source to a systems interconnection type inverter controller. CONSTITUTION: A signal transfer section 18 selects an inverter output voltage detecting signal (d) as a feedback signal during starting. This feedback signal is compared to a reference sine wave signal (b) generated by a signal arithmetic processing unit 19 in an error amplifier 17. This result is output to the PWM controller 16, and the amplitude of the signal (d) is made equal to the amplitude of the signal (b). Amplitude of the signal (b) is determined in such a manner that the inverter output voltage becomes equal to or several volts higher than the setting voltage for the commercial system voltage. The signal arithmetic processing unit 19 outputs the signals for closing an interconnection relay 10 and also outputs signals for transferring the feedback signals from signal (d) to inverter output current detecting signal (c) to the signal transfer section 18.

Title: Method for measuring concentration of oxygen by using solid electrolyte
Inventor: USUI TOSHIO
IPC: G01N27/41
Filed: 1986-10-08
Abstract: PURPOSE:To measure the concn. of oxygen by using a solid electrolyte consisting of a perovskite type oxide having conductivity to both of a hydrogen ion and oxygen ion. CONSTITUTION:Porous platinum electrodes 12, 13 are provided on both faces of the solid electrolyte 11 consisting of the perovskite type oxide having the hydrogen ion conductivity and the oxygen ion conductivity in combination. One of the electrodes is used as an anode 12 and the other as a cathode 13 and a cap 15 formed with a microhole 14 is joined to the electrolyte 11 so as to cover the anode 12. The gas diffusion of hydrogen is limited by the microhole 14 provided on the anode 12 side and, therefore, the current with the hydrogen ion as a carrier decreases to a negligible level when a DC voltage is impressed between the two electrodes 12 and 13 of such oxygen sensor. Since the limiting current of this time is proportional to the concn. of the oxygen, the concn. of the oxygen is known by measuring the limiting current.

Title: Display tube display type electronic equipment
Inventor: NAKAYAMA HITOSHI
IPC: G09G3/20
Filed: 1988-09-21
Abstract: PURPOSE:To save the electric power by switching the control signal received from a specific output board so as to stop the power supply to a converter at count-up of a counting means or at detection of a pushing action of an OFF key. CONSTITUTION:When a key input operation is interrupted, a counting means of a CPU 1 starts its counting action. Then the counting means is set in a count-up state after a prescribed automatic power OFF time. Thus a signal of a high level, for example, is outputted from a specific output board and the power supply is stopped to a converter 3. As a result, the display voltage is not supplied to a fluorescent display tube 4 and therefore the display disappears. In such a constitution, the power consumption is reduced. At the same time, the CPU is set in a stand-by state and the input contents are held since the power is supplied directly to the CPU 1 from a power supply part 7.

Title: Infrared detecting apparatus
Inventor: TAKAHARA NORIMITSU
IPC: G01J1/02
Filed: 1990-09-07
Abstract: PURPOSE:To prevent stray light from entering an infrared detecting element by processing a peripheral part of the infrared detecting element to prevent reflection, and making the reflectivity of the peripheral part not larger than 0.1. CONSTITUTION:A heat proof paint film 14 is coated on an upper surface of a base 10 onto which an infrared detecting element 11 is mounted. The reflectivity of the base 10 is set to 0.05-0.02. Accordingly, even if unnecessary infrared rays reach the peripheral part of the element 11, the infrared rays are hardly reflected, thereby greatly reducing the possibility that the reflecting light enters the element 11 as stray light. A thermography is thus prevented from being deteriorated in its resolution and is hardly influenced by the stray light when detecting the intensity of infrared rays.
