Title: Manufacture of semiconductor device
Inventor: MORITA KIYOYUKI
IPC: H01L21/308
Filed: 1987-11-11
Abstract: PURPOSE:To entirely eliminate a foreign matter on the surface of a semiconductor substrate after an etching is finished by diluting an etchant with a solvent while dipping the substrate in the etchant, and mixing it with a silane coupling agent. CONSTITUTION:A semiconductor substrate 1 is dipped in an aqueous hydrofluoric acid solution 10. The substrate 1 is dipped in the solution 10 for a predetermined period of time, and a silicon oxide film 2 except a region protected by a silicon nitride film 3 is etched. Then, pure water 11 is added to the solution 10 to dilute the solution 10. After the solution is diluted with a solvent, a silane coupling agent 12 is mixed in the solution. The agent 12 is absorbed into the surface of the substrate in the solution. After it is left to stand for 3min in this state, the substrate 1 is removed into the air. Since the agent 12 is absorbed into the surface of the substrate, the whole surface of the substrate becomes hydrophilic, and a foreign matter is not formed thereon. Thereafter, the substrate 1 is dried by a rotary type drying machine or the like.

Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To make the shutter small to use the space effectively and to simplify the operation by adopting the focal plane shutter having a set of shutter blades for a polarization member of an image pickup element. SOLUTION: The camera is provided with an image pickup element of a charge storage type that receives luminous flux from an object to store charges and with a focal plane shutter 11 with a set of shutter blades 11a that is switched between a closing state to shut object luminous flux to the image pickup element and the opening release state releasing the light shield. A control means 101 controls drive means driving the shutter blades 11a so that the drive means starts storing charges of the image pickup element when the shutter blades are in the light shield release state and sets the shutter blades 11a to the light shield state after the end of storage of charges.  Since the focal plane shutter 11 is used only to shield light for the CCD 77 after the storage of charges, it is not required to provide two sets of shutter blades for the operation with high accuracy and one set of the blades are enough for the purpose.

Title: Rolling machine
Inventor: HOTANI SETSUO
IPC: B24B7/12
Filed: 1994-11-21
Abstract: PURPOSE: To efficiently prevent the diffusion of spray out of a housing by connecting an air blow port to an air duct and a suction port to a suction duct so as to suck the air inside of the housing. CONSTITUTION: The spray inside of a housing 12 is discharged out of the housing 12 through suction ports 4, 7 without generating the diffusion of the spray outside through openings 13, 15. Since an air suction port 3 is formed into the slit type port, the air, which is sucked from the air suction port 3 into the housing 12, is formed into the air curtain. This air curtain prevents the flow-out of the air inside of the housing through the opening 13 provided in the housing 12 side wall. Since the air blow port 3 is extended into the housing 12 in the adjacent condition to the housing 12 side wall with the predetermined arrangement, the flow-out preventing effect is maintained well.

IPC: E21D11/04
Filed: 1996-09-24
Abstract: PROBLEM TO BE SOLVED: To make a tunnel inner wall hard to be stained without adhering a sticking material by forming a surface layer containing photocatalyst particles, slicone and a water repellent fluroresin on a base material surface of a tunnel inner wall. SOLUTION: A surface layer containing photocatalyst particles such as a titanium oxide and a zinc oxide, silicone and a water repellent fluororesin, is formed on a surface of a tunnel wall base material. When the exciting light is irradiated to the surface layer, an organic group bonded to a silicon atom of a part of slicone exposed to outside air, is partially substituted with a hydoxyl group, and a hydrophilic property is presented. Both of this hydrophilic part and an exposed part of the water repellent fluororesin are formed as a structure microscopically dispersed on a surface. When the surface is formed in such a structure, both a hydrophilic sticking material and a hydrophobic sticking material do not adhere to a surface, and it can be maintained in a clean condition.
