Title: Power source for pulse charge
Inventor: SUGIURA SAKAO
IPC: B03C3/68
Filed: 1995-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce the number of times of spark discharge generation by making a pulse generator generate impulses so that pulse peak voltage can be kept at a prescribed value or less for a prescribed time at the time when the number of times of spark discharge counted by a counting means exceeds a prescribed one. SOLUTION: In the case spark discharge is generated in an electric precipitator 4, it is detected by a controller 11 in a DC base power source device 1, and also the number of times of the spark discharge is counted. When the number of times of the spark discharge during a prescribed period of time exceeds a prescribed value, a signal to that effect is outputted to a pulse generator 2 for a prescribed time. In this way, the pulse generator 2 lowers pulse spark voltage to a prescribed value or less for a set time to control it so that spark discharge of the electric precipitator 4 can be restrained. The DC base power source for pulse charge 1 performs control so that in the pulse generator 2, pulse charge in which the frequency of pulse voltage generation approaches a set frequency as much as possible can be performed.

Filed: 1990-09-07
Abstract: PURPOSE:To surely detect a mirror part by subtracting a voltage determined according to the level of the output of an RF amplifier circuit, when a slice level signal is prepared based on a peak hold signal being the output of the RF amplifier circuit. CONSTITUTION:Currents outputted from two light receiving parts 11a and 11c among quadripartite photodetectors which receive returning lights from an optical disk, are inputted to an RFI-V amplifier circuit 12, and the currents outputted from the other two light receiving parts 11b and 11d are inputted to an RFI-V amplifier circuit 13, and each of them is converted into a voltage. Then, the slice level signal is prepared by subtracting the voltage decided according to the level of the outputs of the RF amplifier circuits 12 and 13 from the peak holding signal. Therefore, the length of a section at a high level is almost constant at each optical disk at the time of the binarization of a bottom holding signal from the slice level signal. Thus, the mirror part can be surely detected.

Title: Oxygen sensor
Inventor: HIRATE SHINTAROU
IPC: G01N27/406
Filed: 1983-12-17
Abstract: PURPOSE:To make it possible to measure the concn. of oxygen in atmospheric gas by such a simple structure that electrodes are provided to both sides of an oxygen ion conductive solid electrolyte plate and one electrode side is covered with an oxygen gas shielding body through a gap part. CONSTITUTION:Constant voltage is applied between lead wires 4a, 5a from electrodes 4, 5 from a power source 9. In this case, when the concn. of oxygen in the exhaust gas of an internal combustion engine being an atmosphere to be measured of an oxygen sensor 1 is low, the quantity of a current becomes constant at relatively low voltage. On the other hand, when the concn. of oxygen in the exhaust gas is high, the quantity of a current is made constant at relatively high voltage. Therefore, if certain adequate voltage is selected, the concn. of oxygen in the exhaust gas can be measured from the quantity of a current flowed at said voltage. When the electrode 4 is used as a minus side and the electrode 5 is used as a pluse side while voltage is applied therebetween, a solid electrolyte plate 3 is acted as a pumping-up oxygen pump and has action for exhausting only oxygen of a gap part 7 to the side of the electrode 5 through the electrolyte plate 3. An oxygen concn., an oxygen amount and the quantity of a current are proportional to each other.

Title: Air conditioner
Inventor: TOYODA MITSURU
IPC: F24F11/02
Filed: 1997-09-03
Abstract: PROBLEM TO BE SOLVED: To put the desired region within on air-conditioned room efficiently in comfortable ambient condition. SOLUTION: When the mode is set to physical sensation mode, an air conditioner checks whether or not receives the temperature signal sent out from a main remote controller and also whether receives from a sub controller or not (steps 210-214). Here, when it has not received the temperature signal from the sub remote controller, this performs usual control based on the room temperature detected with the room temperature sensor of an indoor unit, or sets the mode to usual physical sensation mode using the main remote controller (steps 216 and 218). When receiving the temperature signals from the main and sub remote controllers, the multicontrol using the main remote controller and the sub remote controller is performed.
