Title: Discharge lamp lighting apparatus
Inventor: KAWAI TSUNETAKA
IPC: H05B41/18
Filed: 1978-01-24
Abstract: PURPOSE:To prolong the life of a discharge lamp by preventing consumption of filaments through sufficient pre-heating of the filament alone of the discharge lamp before application of a high voltage pulse thereto when power is switched on. CONSTITUTION:When the power supply 1 is switched on, the supply voltage is divided by resistors 18 and 20. When the voltage as the resistor 20 reaches the breakover voltage VBO of a two-way/two-terminal thyristor 17, the thyristor 17 conducts, whereby a trigger circuit 7 operates to provide a gate 16 of a two-way/ ghree-terminal thyristor 13 with a gate current. Thus, the thyristor 13 is caused to conduct for the same period as the thyristor 17 does to provide filaments 4 and 4' with a pre-heating current. On the other hand, when the voltage of a capacitor 29 being charged with the voltage generated by a current limiting device 2 reaches the breakover voltage VBO of a thyristor 23, the thyristor 23 conducts, whereby only half-wave component is made conductive through a thyristor 22. With such an arrangement, the pre-heating is suspended, while the discharge lamp 3 comes on.

Title: Analog signal input circuit
Inventor: KAWASAKI MASAYUKI
IPC: H03K17/693
Filed: 1989-01-17
Abstract: PURPOSE:To prevent the accuracy of an A/D converter from decreasing by connecting a well in an analog signal selecting circuit so that the conduction directions of the parasitic P-N junction diodes between drain electrodes of the MOS FET of one channel constituted in the well are opposite. CONSTITUTION:For example, an analog signal in a range of 0-5V is applied to an analog signal input terminal IN1 and +10V is applied to an IN2. At this time, a collector current I CP2 flows as the base current I of a bipolar transistor PNP3 and the collector current I CP3 of a BP3. Here, bipolar transistors PNP2 and PNP3 are parasitic lateral transistors formed when an MOS FET is constituted and their current gains a are 0.5-0.6. when the current gains of the PNP1, PNP2, and PNP3 are 0.6, a current which flows from the input terminal IN2 to the analog signal is reduced to about 0.6 time as large as a conventional current. Consequently, the error of the analog signal is reducible.

Abstract: PURPOSE:To improve wettability with a treating liquid of the whole material to be treated, and to prevent the nonuniformity of treatment by exposing the material to be treated in a liquefied or gassy substance having compatibility with the treating liquid prior to the treatment of the material to be treated. CONSTITUTION:A wafer type treating liquid is used for etching and rinsing an Si substrate, the surface thereof has fine irregularities. A substance, which has small adsorptivity to Si, is easy to be replaced with the water type treating system and has a hydrophilic group and a hydrophobic group in a molecule thereof, methanol acetic acid, acetone, etc., their mixture and a mixture with water are employed as a liquid or a gas having compatibility with the water group treating liquid. When the Si substrate is dipped or brought into contact to the liquid, the hydrophilic groups and hydrophobic groups selectively deposit on the surface, and the Si substrate is easy to be wetted by hydrophilic and hydrophobic treating liquids as a whole. Since a deposit has compatibility with the water group treating liquid and is dissolved during treatment and has small surface tension, bubbles are easy to be desorbed, and the Si substrate can be treated uniformly. Lastly, the adhering treating liquid is washed away by a pure water.
