Title: Fine gas leakage detector
Inventor: KENJO TSUNEO
IPC: F17D5/02
Filed: 1994-03-04
Abstract: PURPOSE:To efficiently collect data for correct judgment of gas leakage, record it, and save recording paper and a memory capacity. CONSTITUTION:A fine gas leakage detector 20 detects a flow rate of gas flowing in a gas supply pipe 8 for feeding the gas from a gas supply source 1 toward a combustor. Only the minimum flow rate out of flow rates is stored in a RAM contained inside a microcomputer 23, which judges on the basis of the minimum flow rate stored in the RAM whether or not the gas finely leaks. Consequently, data for correct judgment of gas leakage can be efficiently collected and recorded. The collected data is printed monthly and annually by a recorder 10, thus saving recording paper and a memory capacity.

Abstract: PURPOSE:To improve performance by forming a buried-layer removing section along a groove to a buried layer having a conduction type reverse to a substrate and burying the removing section by a buried layer having a conduction type the same as the substrate. CONSTITUTION:An silicon dioxide (SiO2) film 9 with opening sections for forming grooves in double channels in parallel with a striped light-emitting section is laminated on a substrate to which a double hetero-junction consisting of InGaAsP is shaped. Double channel sections 10 are formed through etching by Br-methanol while using the silicon dioxide film 9 as a mask. P-InP 7 is buried, the grooves 11 are shaped to the bottom section of the InP layer 7 while employing the silicon dioxide film 9 as a mask, and N-InP layers 12 are grown. The silicon dioxide film 9 is removed, an electrode contact section is removed newly and an silicon dioxide film 13 is grown as an insulating film, and a P electrode 5 and an N electrode 6 are formed. Accordingly, P-N-P junctions are shaped even to leakage currents passing in the lateral direction through the channel sections, thus preventing leakage currents.

IPC: C09D13/00
Filed: 1979-03-27
Abstract: PURPOSE: To obtain color pencil leads having improved stability against discoloration, improved dispersion uniformity of colorant and excellent performance, by employing a silicone varnish as a binder for refractory pigments and refractory white powders.  
     CONSTITUTION: To 5W50pts. of a liquid silicone varnish are added 16W70pts. of refractory white powders, 10W78pts. of a refractory pigment and 3W40pts. of a highly heat-stable silicone oil which acts both as a dispersant and as a molding lubricant and also protects the body material from discoloration during baking. The resulting mixture is kneaded and extruded into leads through an extruder. The extruded leads are dried at such a temperature (5W80°C) as to completely evaporate the remaining solvent without formation of bubbles and not to cause crazing and blistering of the leads. Then, the leads are treated at a temperature of 110W300°C to completely heat-cure the silicone varnish and thereby to produce the leads of the purpose. As the refractory white powders, titanium oxide, talc or boron nitride is particulary preferred, because of their excellent hiding power and slip.

Filed: 1992-02-24
Abstract: PURPOSE:To simplify the circuit by generating a pulse equivalent to a pulse width of a pulse tip for a flyback period for horizontal deflection signal so as to generate a pulse near the center of an FBT pulse even when the horizontal frequency is changed. CONSTITUTION:When an FBT pulse with a proper level is fed to a base of a transistor(TR), the pulse is clamped at a tip of the FBT pulse with a diode between a base and an emitter of the TR. In this case, the TR is turned on and a load resistor 3 is connected to the collector of the TR and a prescribed pulse is extracted from the collector of the TR. The resistor R1 is a resistor to limit a base current at clamping, a resistor R2 is a resistor to discharge the charge charged in capacitors C1, C2 and the resistance of the resistor R2 is selected as to be large to make the width of the pulse extracted from the collector of the TR narrow. As a result, even when the horizontal frequency is changed, the pulse is generated almost at the center of the FBT pulse with a simple circuit.
