Title: Sealant for concrete member
Inventor: HASEGAWA REIJI
IPC: E03F3/04
Filed: 1993-08-19
Abstract: PURPOSE:To prevent the water leak of a concrete joint part completely by forming sealant, interposed at the time of jointing concrete members, of a single body or a compound body of solid rubber, sponge, water expansive sponge rubber and water expansive rubber, and combining continuous foam sponge as auxiliary material. CONSTITUTION:A continuous foam sponge body 30 as an auxiliary body is stuck to the relative face of a water expansive sponge body 24.

Title: Focal position control method
Inventor: OOGOSHI SEIICHI
IPC: G11B7/085
Filed: 1983-12-05
Abstract: PURPOSE:To obtain quickly a focused state with no runaway even in case the focal point of a condenser lens gets out of a surface to be detected, by limiting the irradiating area on the photodetecting surface of a photodetector and controlling the integration value of an error detecting signal. CONSTITUTION:For a photodetector 17, the irradiating area of the photodetecting surface is limited to 1.5 times as much as the beam diameter 2Wo of the reflected light 16 on the photodetecting surface of the detector 17 in a focused state of a condenser lens 14. While the integration value of an error detecting signal Iz in an area A is set smaller than that in an area B. In other words, the integration value of the signal Iz obtained when the irradiating area of the light 16 to photodetecting surfaces 17a and 17b is larger than the irradiating area of a focused state is set smaller than that of the signal Iz obtained when the irradiating area of the light 16 is smaller than that of a focused state. Thus an error detecting signal Ve is equal to 0 at a point Zc although the lens 14 enters an area C after passing through the area B and a focal position Z gets further away from Z=0 when the focal control is carried out with drive of the lens 14. This prevents a runaway of the focal point of the lens 14.

Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To improve workability and to shorten an inspection stage by affixing the other end face of a pellicle frame to a photomask with a tacky adhesive, then spreading a pellicle film to the one end of this pellicle frame. SOLUTION: A tacky adhesive layer, such as silicone tacky adhesive, is formed at the end face to be adhered and fixed to the photomask of the pellicle frame. This formed tacky adhesive layer is then stuck by a pressure to the photomask to stick the pellicle frame to the photomask. After the pellicle frame is affixed to the photomask, the pellicle film is stuck to the one end face of the pellicle frame. The pellicle film is spread after the photomask is stuck to the pellicle frame in such a manner, by which the possibility of the adhesion of foreign matter to particularly the insides surface of the pellicle film is only at the time of spreading of the pellicle film and the possibility of the adhesion of the foreign matter on the pellicle film is substantially eliminated.  The inspection of the adhesion of the foreign matter to the pellicle film is necessitated to be just once after the spreading of the pellicle film.

Title: Semiconductor device
Inventor: YAMANAKA KAZUO
IPC: H01L29/732
Filed: 1988-09-13
Abstract: PURPOSE:To prevent the deterioration of breakdown strength caused by hydrogen ion generated at the time of forming a silicon nitride film by selectively arranging an amorphous or polycrystalline silicon layer in the upper region of a field insulating film in a coating insulative film, in the manner in which said silicon layer does not come into contact with a silicon nitride passivation film, and is kept in an electrically floating state. CONSTITUTION:A non-doped polycrystalline (amorphous) silicon pattern 17 is buried, so as not to be connected with a field plate 10 sandwiched by a first PSG coating insulative film 14A and a second PSG coating insulative film 14B, and an annular ring 13. A good deal of H<+> contained in an Si3N4 passivation film 11, is apt to diffuse in the second PSG coating insulative film 14B and the first PSG coating insulative film 14A and to reach an exposed region of a field insulating film 6. The greater part of H<+> is captured by the energy level of dangling bond and crystal grain boundary existing in the polycrystalline (amorphous) silicon pattern 17. As the result, H<+> loses potential, and is fixed and vanishes, so that the positive charge of the field insulating film 6 caused by H<+> is avoided.
