Patent JP-H07305849-A (JP)
Title: Premixing tube
Inventor: FUJI HIDEMI
IPC: F23R3/32
Filed: 1994-05-13
Abstract: PURPOSE:To reduce unevenness of mixture in combustion area and prevent backfire as well as self igniting by making a hollow cylinder, constituted of an inner tube of a fuel/air premixing tube and an outer tube having a multitude of small holes, with a combustion chamber. CONSTITUTION:The space of a hollow cylinder, constituted of an inner tube 18 and an outer tube 19 of a fuel/air premixing tube 21, 1;e communicates with a combustion chamber 25. The pressure of the inner tube becomes lower than that of outside air due to a pressure loss generated when air flows into the inner tube 18 from outside through the air inflow port 13 of a fuel injection valve 11 at the tip end of the tube and an air flow passage 17 whereby the pressure of the combustion chamber 25 becomes lower than the outside of the outer tube 19. Accordingly, a pressure in the hollow cylinder becomes lower than the outside of the outer tube 19 whereby outside air of the outer tube 19 flows through the small holes 22 of the outer tube 19 and is collided against the outer surface of the inner tube 18 thereby cooling the inner tube 18. The air flows along the bulkhead 26 of the combustion chamber whereby homogeneous mixture can be obtained in combustion area. According to this method, backfire or self igniting, which is readily generated in the low-speed flow area on the inner wall of the inner tube 18, can be restrained.

Title: Photosemiconductor device
Inventor: NOMURA TOORU
IPC: H01L23/31
Filed: 1982-06-10
Abstract: PURPOSE:To improve the productivity of a photosemiconductor device by molding an optical path of a photoconverter, in which an optical fiber is provided, with light permeable resin having an optical filter fitting part, thereby preventing a defect due to flow-in of adhesive and an improper conductivity due to flow-out of the adhesive. CONSTITUTION:A photoelectric converter 1, a semiconductor circuit element 2 and a lead frame 3 are molded with light permeable molding resin 4, a frame fitting part 8 is formed on the upper surface, a visible sensitivity correcting filter 6 is placed, and secured with transparent resin adhesive 7. Then, the outer surface of the resin 4 is covered with light opaque molding resin 5 except a light incident window 9. Before the filter 56 is secured, even if liquid adhesive 7 is accumulated in the part 8 and a gap is produced due to thermal expansion or contraction between the resin 4 and the resin 5, the adhesive 7 does not flow in, and improper conductivity of the externally led wirings 3 does not occur.
Patent JP-H1070097-A (JP)
Title: Method of planarization of semiconductor substrate
Inventor: CHIN RAIJYO
IPC: H01L21/304
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To enable monitoring the removed layer thickness without removing particles from a polishing equipment, at the time of chemical/mechanical polishing(CMP) of a semiconductor substrate. SOLUTION: A polishing pad 19 is rotated while polishing slurry at about 10-30 deg.C is supplied on the pad from a resolver 21. A semiconductor substrate 12 held by a carrier 11 is pressed against the polishing pad and rotated, thereby flattening the semiconductor substrate. The temperature at a specific position of the polishing pad or the semiconductor substrate is measured by using an infrared sensor 22, and is stored in a computer memory 25, in accordance with the passage of polish time. The temperature versus the polish time is integrated with time. The thickness of a removed layer is obtained as a function of polishing time, by the calculation using the integrated value and integration coefficients relating to the CMP removed chemical substances and the pattern density on the under side.

Title: Comparator with hysteresis in photodetecting circuit
Inventor: SAWAI TAKANORI
IPC: H04B10/60
Filed: 1984-05-17
Abstract: PURPOSE:To obtain a comparator with hysteresis where the hysteresis width is narrow, the amount is constant and no error exists in the direction by using two-stage differential amplifier circuits and a constant current circut and obtaining an input of the 2nd stage amplifier circuit symmetrically from the collector of the amplifier circuit of the 1st stage. CONSTITUTION:Compared voltages y, x (x is a mean value of y) are inputted to bases of transistors (TRs) Q13, Q14 vis resistors R9, R8. In flowing a current to the resistor R8 in the direction from (x) to (k) or from (k) to (x), the input (k) is increased or decreased. The currents have the same absolute value but different sign. Current values I7, I8, I9 of the constant current circuit are all equal and the relation of IK=2IO exists, the bipolar hysteresis is given accurately and the width is narrowed. The offset is reduced by taking an input of the differential amplifier circuit of the 2nd stage symmetrically from collectors l, m of the TRs 13, 14. One of the input of the said amplifier circuit is zeroed without fail by adjusting the difference between the output of the differential amplifier circuit of the 2nd stage and the input DC level by means of diodes D1-D4, D5-D8. One of the TRs Q15, Q16 is turned off completely.
