Abstract: PURPOSE:To improve efficiency of inspection by a method wherein an element probing electrode is retained, at least until the end of automatic characteristics measurement, either between beam leads stretching from an element region into an element isolating region or in an isolating region facing a corner of the element region. CONSTITUTION:An Si substrate is separated into a plurality of element regions 2 by isolating regions 1 of a width (w). Beam leads 3 are formed to stretch from a region 2 into an isolating region. Electrodes 4 to be contacted by element probing sensors belonging to an automatic characteristics measuring device are respectively built, one in an isolating region 1 immediately facing a corner of an isolating region 2 and the other between beam leads stretching from the lower side of an element region 2. The electrodes 4 are smaller in area than the beams 3 but are large enough to easily accept the sensors. Their adhesion to be element region 2 needs not to be so strong.

Filed: 1991-10-16
Abstract: PURPOSE:To rapidly and accurately detect the life of a sensor by providing a life informing means emitting a signal when the detection output to reference gas is shifted from a predetermined range to a gas detection part. CONSTITUTION:The component of gas to be detected transmits through a solid electrolyte layer 80 to reach an acting electrode 20 to generate electrochemical reaction.

Title: Chrolinated rubber and production thereof
Inventor: KIMURA ITSUO
IPC: C08C19/14
Filed: 1993-09-30
Abstract: PURPOSE:To obtain a chlorinated rubber which is improved in processability and reactivity, soluble in an organic solvent, and easy to handle by adding a surfactant and an acid to a rubber latex and chlorinating the rubber in an aqueous medium under specific conditions. CONSTITUTION:The chlorinated rubber production process comprises adding a surfactant and an acid to a rubber latex and chlorinating the rubber with chlorine gas in an aqueous medium until the chloride content of the rubber reaches 60-75%, during which the system is heated at least once to a temp. higher than the softening temp. of the rubber to coagulate rubber particles after the chlorine content has exceeded 50%. The chlorination in the initial stage is desirably conducted at 50 deg.C or lower, because too high a temp. in the initial stage tends to result in coarser particles. The temp. for initial chlorination is preferably 30 deg.C or lower, because the rate of reaction is high in the initial stage and the reaction is exothermic. The reaction in this stage proceeds rapidly without a catalyst, e.g., light so that light irradiation is unnecessary.

Title: Method of controlling pwm converter
Inventor: NAGAI IKUO
IPC: H02M7/12
Filed: 1989-10-18
Abstract: PURPOSE:To prevent the distortion of input currents by using a signal obtained by adding a compensatory signal having a frequency which is three times the frequency of a voltage command signal to the voltage of the voltage commands of each phase as a new voltage command. CONSTITUTION:A triple harmonic generator 16 forms the signal (a triple harmonic wave) 3f of a frequency which is three times the frequency of voltage commands Vrefu, Vrefv, Vrefw from a current amplifier 4. The triple harmonic 3f is added to the voltage commands Vref of each phase, and new voltage commands VAref are formed. A PWM conversion circuit 5 compares the new converter voltage commands VAref with PWM carriers, and generates a PWM signal SPWM. The signal SPWM operates a PWM converter 6, and outputs converter input voltage by sine waves. Accordingly, converter input currents Ifbu, Ifbv, Ifbw are also changed into sine waves. That is, triple harmonic waves are overlapped to the voltage commands, thus making percentage modulation larger than 1 without distorting converter the input currents.

Title: Inclined photocatalytic filter
Inventor: HATTORI YOSHITAKA
IPC: A61L9/20
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To enable the decomposition and deodorization of waste gas, the cleaning of air, the treatment of sewage and waste liquor, etc., by using a photocatalytic filter obtd. by obliquely cutting a honeycomb or corrugated cardboard-shaped photocatalytic body at a certain angle. SOLUTION: When a photocatalytic body is obliquely cut 6 as shown by dotted lines, the area of cut sections is increased by >=1.5 times. Mark 7 shows an enlarged drawing of one hole. Since open faces are enlarged and a tilt angle is imparted to the depth, the catalyst is irradiated with oblique UV and its photocatalytic effect is enhanced. The excitation of the photocatalyst is more preferably carried out by irradiation with UV at an acute angle than in parallel with the catalyst face since it is dependent on the quantity of UV. Since absorption efficiency is enhanced by increased surface area owing to inclined open faces and acute UV irradiation, the extent of excitation is doubled.
