Patent JP-H01186656-A (JP)
Title: Semiconductor device
Inventor: TOYAMA YOSHINOBU
IPC: H01L29/78
Filed: 1988-01-14
Abstract: PURPOSE:To increase electrostatic withstand voltage directly below input circuit protection resistance and to improve quality by forming a dummy pattern simultaneously with gate wire directly below input circuit protection resistance. CONSTITUTION:A LOCOS2, an insulation film between layers 3, an input circuit protection resistance 4 formed by the second layer wiring, an insulation film between layers 5 between a second layer wiring and Al wiring, an Al wiring 6 which connects an input circuit protection resistance 4 to input terminal and input circuit, and a dummy pattern 7 formed simultaneously with a first layer gate wiring are provided on a substrate 1. Namely, since the dummy pattern is formed at the upper part of the LOCOS 2, the surface of LOCOS2 is not directly etched in the wet etch process and dry etch process until the insulation film between layers 3 is formed, thus preventing film thickness of the LOCOS2 from being reduced. It allows electrostatic withstand voltage directly below the input circuit protection resistance to be increased for improved quality.

Title: Offgas treatment facility, iodine absorbent, and their manufacture
Inventor: KONDOU YOSHIKAZU
IPC: B01D53/68
Filed: 1993-01-18
Abstract: PURPOSE:To highly efficiently separate and remove iodine even under severe conditions of non-coexistance of NOX and an extremely high humidity in an offgas treatment facility, an iodine adsorbent, and their manufacture. CONSTITUTION:An iodine adsorbent 24 impregnated with two kinds or more silver compounds is charged in the adsorption tower of an offgas treatment facility. As the silver compounds, at least one kind each of an easily soluble silver compound and a hardly soluble silver compound is used. For example, in the inner part of the pore 4 of an activated alumina 3 which is the carrier of the iodine adsorbent 24, silver nitrate 1 having a porous structure and metal silver 2 are impregnated in laminated form. By working them as the adsorbent in this structure, both peeling of the impregnated silver and reduction in the removing efficiency of organic iodide can be suppressed. A relatively large quantity of silver can be impregnated in the iodine adsorbent.

Title: Variable attenuator
Inventor: ARA YOICHI
IPC: H03H11/24
Filed: 1986-01-14
Abstract: PURPOSE:To obtain a constant resistance variable attenuator which can be used at a wide band from a direct current and in which a distortion characteristic will not be changed with an attenuating quantity by constituting a variable attenuator of two electric field effects and specifying the relation of two gate voltages. CONSTITUTION:The resistance values Z0, Vp1 and Vp2 of resistances 5 and 6 are respective pinch-off voltages of electric field effect transistors 3 and 4, the output of amplifiers 55 and 56 is deviated only for the part of the collector emitter saturated voltage of transistors 51 and 52 from 0V, and then, the output voltage of terminals 8 and 9 is changed from the 0V to the Vp1 or Vp2 in accordance with the change of the input voltage of a terminal 60, and the relation satisfies (Vgs1-Vp1).(Vgs2-Vp2)=constant. Thus, the variable resistor can be operated while the constant resistance of a characteristic impedance Z0 is kept. The signal attenuating characteristic comes to be a passage loss minimum at the time of Vgs1=0V and a passage loss maximum at the time of Vgs2=0V.

Title: Motor control circuit
Inventor: FUKUSHIMA NOBUO
IPC: H02P7/00
Filed: 1986-01-14
Abstract: PURPOSE:To control a motor so that much current flows when the motor is driven at a high speed and a little current flows when the motor is driven at a low speed, by providing two circuits to limit currents flowing in control terminals of transistors. CONSTITUTION:At the Start mode time, being different from the Normal mode time, Since a transistor (Tr) 20 is rendered on to output of the base circuit G for the Start mode in place of the operation amplifier section B, the base current of the Tr 20 is large in comparison to the case that the Tr 20 is rendered on by the output of the operation amplifier B. Consequently, voltage applied to a terminal 9 in the Start mode time becomes higher than in the Normal mode time, and the motor M can start the driving at rising of higher speed.

The number of revolutions of a motor 18 is lowered to decrease a blasting quantity, by which the operating current of the heater 13 is lowered when the output value is larger than the prescribed value. The number of revolutions of the motor 18 is raised to increase the blasting quantity, by which the operating current of the heater 13 is raised when the output value is smaller than the prescribed value. The operating current of the heater 13 is controlled in such a manner so as to be kept constant.  The in-housing temp. of the clothes-drying machine is high when the power-supply voltage and outdoor air temp. are high and, therefore, the upper limit value of the number of revolutions of the motor 18 dealing with the power-supply voltage and the outdoor air temp. is set, in such a case, in order to lower this temp.
