Title: Manufacture of semiconductor integrated circuit device
Inventor: TAKADA TOMOJI
IPC: H01L21/3205
Filed: 1980-10-28
Abstract: PURPOSE:To provide a satisfactory connecting hole in an MOS element having favorable yield with rough mask positioning by a method wherein formation of opening for the connecting hole in relation to a diffusion layer is performed on self- alignment bias utilizing the etching back technique. CONSTITUTION:After the normal MOS process is performed, an Si3N4 film 18 is accumulated on an SiO2 film 15, a resist mask 16 having a hole 16a is formed by the photo-engraving technique with precision of about 12mum. When the Si3N4 film 18 is etched next, the Si3N4 film 18 is remained at the neighborhood of the resist wall and at the step parts of a gate electrode 14, a field oxide film 12. When the SiO2 film 15 is etched making the remained film 18 as a mask, the self-alignment connecting hole 19 can be obtained. After then the resist mask 16, the Si3N4 films 18 are removed to complete the MOS element. By this constitution, the margins a, b of the hole are changed by the thickness of the films 15, 18, and by adding quantity of H atoms to etching gas in the etching opening treatment, and when those are selected properly, a and b can be made to about 1mum, and the highly precise window can be formed through rough mask positioning.

Title: Garbage incinerator combined with water heater
Inventor: HIKI HIDEO
IPC: F24H9/00
Filed: 1980-10-28
Abstract: PURPOSE: To ensure the supply of a high temperature water for a short time by erecting a chimney at the top of an incinerator surrounding the entire equipment with a water tank communicated to a water feeding tank with an automatic water feed valve.  
     CONSTITUTION: When water is fed into a waer feeding tank 11 through a blower 14 and an automatic water feed stop valve 13, it enters a water tank 6 from below due to a head passing through a water feed pipe 12, reaches the upper limit water level of a hot water port 9 and then, the automatic water feed stop valve 13 closes to halt the supply of water. Subsequently, as a combustible garbage or other matter to be burned is dumpted at burning matter dump port 3 and ignited, flame is sucked into a chimney 2 heating the incinerator 1 while these components are heated with the result that the warmed water in the water tank 6 becomes light and rises. Particularly at the top of the water tank 6, lukewarm water prewarmed at the lower part enters a narrow space with the internally erected chimney 2. Thus, the small amount of lukewarm water rapidly rises in the temperature coming into contact with a broad surface and gathers at the top of the water tank 6.

Title: Sewage treatment facilities design aiding device
Inventor: SAITO YUTAKA
IPC: G06F17/50
Filed: 1991-06-24
Abstract: PURPOSE:To provide an aid device for pressure type sewage treatment facilities and for the selection of the pipe diameter in particular by determining the pipe diameter based on a drainage flow pattern planned realistically. CONSTITUTION:A drainage flow pattern by which drainage flows out of a pump 13 to a pressure feed pipe 12 when drainage attains a set water level, is formed based on the drainage forming pattern by which drainage flows in a drainage tank 10, based on which, a pipe path having a pipe diameter capable of securing the lowest flow speed is selected. This constitution thereby prevents flow capacity from being in want because the pipe is too small in diameter, and also prevents human waste from being stacked up and clogged with the pipe path because the pipe is too large in dismeter while the set lowest flow speed can not be assured, so that the set lowest flow speed can thereby be surely maintained. A design which possibly causes human waste to be stacked up and clogged within the pipe path, can thereby be avoided.

Title: Hollow yarn filter
Inventor: SASAKI MASANORI
IPC: B01D63/04
Filed: 1987-06-19
Abstract: PURPOSE:To introduce raw water to the central part of a module and to prevent the compression of a hollow yarn bundle by separating the inside of a vertical sleeve into many chambers by a hollow partition plate having a crossed cross section, and providing a spacer on the outside of the partition plate to prevent the adhesion between the hollow yarn and the partition plate. CONSTITUTION:The inside of the vertical sleeve 1 is separated into four independent sectorial spaces by the hollow partition plate 2 having a crossed cross section, hollow yarns 4 opened on the upper and lower ends are packed in the spaces 3, the hollow part in the partition plate 2 is used as the passage 5 for filtered water, and an external pressure-type hollow yarn module for filtering a liq. is formed. In this case, the spacers 6 extending in the horizontal direction and arranged at appropriate vertical intervals are provided in stages on the outer side of the partition plate 2 to prevent the adhesion between the yarn bundle and the partition plate 2, and a horizontal raw water inflow passage extending to the innermost recess of the module between the partition plate 2 and the yarn bundle is formed between the upper and lower spacers 6. Since the hollow yarn bundle is separated into four sections, the yarn bundle is not compressed by the inflow pressure of raw water, and a decrease in the filtration performance is reduced.

Abstract: PURPOSE:To decrease a power consumption quantity, to suppress a temperature rise in the circuit and to improve the reliability of an action by decreasing the value of a power source voltage supplied to a current adjusting circuit lower than the value of the power source voltage supplied to a constant current circuit. CONSTITUTION:A current adjusting circuit 3, when a second current IC2, namely, an output current is changed, generates a third current IC3 to cancel the changing part. Based on the third current, a first current IC1 of a constant current circuit 2 is adjusted and an output current IC2 is unified. At such a time, at a current adjusting circuit 3, a current IC4 flows from a low order power source line L2 to the constant current circuit 2 side and a power consumption equivalent to a voltage VCC2 and a current lC4 occurs. Thus, by decreasing the power source voltage supplied to the current adjusting circuit 3, the power consumption quantity is decreased, the temperature rise in the circuit is suppressed and the reliability of the action is improved.

Title: Method of coating the resonator end surface of semiconductor laser
Inventor: SHONO MASAYUKI
IPC: H01S5/00
Filed: 1988-06-20
Abstract: PURPOSE:To make it possible to adhere a dielectric film to a resonator, end surface without inducing a thermal deterioration of a semiconductor laser by forming a dielectric film on the resonator end surface of a semiconductor laser by using a spin-on coating method. CONSTITUTION:A semiconductor laser 2 in which an active layer 1 is made of In0.48Ga0.52P is prepared. The semiconductor laser 2 is cleaved to form a pair of resonator end surfaces 3, 4. An SiO2 film 5, 1113Angstrom  in film thickness, is formed on one of the resonator end surface 3 by using a spin-on method. On the other resonator end surface 4 is formed an SiO2 film 6 of about the same film thickness, and on this SiO2 film 6 is formed a polyimide film 7 of 934Angstrom or thereabouts by using a spin-on method. This process is repeated two times, and further two layers of the SiO2 film 6 and the polyimide film 7 each are alternately laminated. As a result, since a rise in temperature in the semiconductor laser resonator end surface due to collision of film materials at dielectric film formation time is suppressed, a dielectric film can be adhered to the resonator end surface without causing a thermal deterioration in a semiconductor laser.
