Patent JP-S63294193-A (JP)
Title: Demagnetizing circuit
Inventor: NAGASAWA YUJI
IPC: H04N9/29
Filed: 1987-05-27
Abstract: PURPOSE:To reduce the cost and number of used parts and, at the same time, to eliminate the necessity of pulse control from an electric secondary side, by respectively connecting one ends of 1st and 2nd resistances, whose other ends are connected to the gate electrode of a triode AC switch, with the connecting point of a positive- characteristic thermistor and demagnetizing coil and an electrode provided on the AC input source side. CONSTITUTION:When a switch 2 is turned on, an electric current is made to flow to resistances 6 and 7 through a positive-characteristic thermistor 3 and a trigger voltage is applied to the gate electrode of a triode AC switch 5. As a result, the switch 5 is turned on and a gradually decreasing electric current is made to flow to a demagnetizing coil 4 as a demagnetizing current. On the other hand, the trigger voltage applied to the gate electrode of the triode AC switch 5 also becomes a gradually dropping AC voltage by the action of the thermistor 3 and, after a fixed time, further drops to a level which is lower than a prescribed level required for turning on the switch 5 and the triode AC switch 5 is turned off because an AC voltage of the opposite polarity is applied to the main electrodes of the switch. Therefore, the pulse generating circuit which is required for controlling the turning on and turning off of the switch 5 as a switching element becomes unnecessary.

Title: Magnetic tape device
Inventor: YOSHIMARU TOMOHISA
IPC: G11B27/10
Filed: 1979-10-09
Abstract: PURPOSE: To always ensure an accurate reproduction for only the information signal without being affected any of the travelling velocity and the expansion/contraction of the tape, by producing the envelope signal out of the reproduction information and then detecting the frame position on the tape based on the discrete value of the envelope signals.  
     CONSTITUTION: The video information is recorded by detecting the positions of the blocks 0W255 on the tape 3 and based on the contents of the tape counter. And the video information is reproduced by detecting the frame position on the tape 3 and based on the count contents of the envelope signals after producing the envelope signal of the information signal 8 2  based on the output of the head 9 and also counting up the envelope counter within the conrol unit 12 and by the envelope signal. Accordingly, only the desired video information can be reproduced at all times out of the designated record position without being affected any of the travelling velocity and the expansion/contraction of the tape 3.

Title: Semiconductor integrated circuit device
Inventor: SHIMAMURA AKIMITSU
IPC: H01L21/822
Filed: 1988-05-27
Abstract: PURPOSE:To make the title device have an excellent protective effect on overvoltage by connecting diffusion resistance, parallel to each other and each having a reversed polarity, to an input terminal. CONSTITUTION:A resistor 7 by diffusion layer in reversed polarity to a resistor 3 is inserted in parallel with the resistor 3 which was used in the past. Accordingly, in case that positive overvoltage was added, two paths through a diode 4 and a diode 1 via resistor 3 arise, while in case that negative overvoltage was added, two paths that the overcurrents flow from GND to a resistor 7 bia a diode 8 and to the resistor 7 via a diode 2 also arise. Hereby, the current density of overcurrents per resistor is reduced to half and protective function to the thermal breakdown of the resistor is also strengthened.

Title: Oil dropping preventive device
Inventor: PERU FURETSUDOSUTETSUDO IENSEN
IPC: F23D11/44
Filed: 1991-06-03
Abstract: PURPOSE: To reduce the amount of oil scattered and lost from a nozzle, by continuously controlling the temperature of the oil while a combustion system is operated by means of an electric heating element, so that the volume of the oil in a nozzle holder and an oil heating unit may become constant. CONSTITUTION: When an oil combustion system is turned on, a first electric heating element 1 which is in contact with an oil supplying pipe maintains oil at a fixed temperature by heating the oil. When a boiler temperature control unit 13 sets the temperature of a boiler too low, an oil pump and an air supplying fan are turned on and a switch 12 is closed, resulting in the turning on of a second electric heating element 2. When cold oil is supplied, the second electric heating element 2 is turned on and, when the supply of the oil is interrupted, the element 2 is turned off. Therefore, the oil can be maintained at a fixed temperature by keeping the oil in a heated state with a low thermal output and, accordingly, the pre- and post-dripping of oil from a nozzle can be prevented, because no large thermal expansion occurs.
