Title: Method for curing photosensitive resin composition
Inventor: BANBA TOSHIO
IPC: C08G73/22
Filed: 1995-11-27
Abstract: PROBLEM TO BE SOLVED: To remarkably suppress coloring after curing by exposing and developing a photosensitive resin compsn. consisting of a precursor of polybenzoxazole and diazoquinone to form a pattern and then carrying out full surface exposure and curing. SOLUTION: A photosensitive resin compsn. consisting of a precursor of polybenzoxazole and diazoquinone is exposed and developed to form a pattern and then full surface exposure and curing are carried out. The diazoquinone as a photosensitive agent causes a chemical change by exposure, forms indenecarboxylic acid and becomes soluble in an aq. alkali soln. Since the diazoquinone reduces its light absorption by exposure and becomes transparent, light reaches the bottom of a film of the compsn. and development is enabled. The compsn. is exposed and developed to form a pattern, the full surface of the unexposed part is exposed and a light-colored film is obtd. by curing.

Filed: 1997-10-21
Abstract: PROBLEM TO BE SOLVED: To give a more beautiful appearance to a water closet by providing a lid body in an openable manner separated from a hand wash basin, which opens the basin surface of the hand wash during use and closes the basin surface when not used. SOLUTION: A casing 16 is placed on and fixed to an upper surface of the rear portion of the main body 10 of a water closet with a closet seat 12 and a closet cover 14 held in an openable manner below the casing. Also, an operation lever 22 for discharging the washing water is provided at the surface of the casing 16. In addition, a hand wash basin 28 is provided above the casing 16, and the basin surface 30 can be opened or closed by rotating a lid body 32 with a bearing 34 and a shaft 36. Then, the base surface 30 is opened when using the water closet and closed when not used with a lid body 32 provided separately. In this way, dirt stuck on the basin surface 30 cannot be seen. By doing this, a better appearance can be maintained around a washing water tank device 18 or the area around the water closet, and a discharge hole 50 is concealed when no hand is washed.  Thus, no appearance is degraded and the user can stand in an adequate area for conveniently washing the user's hands.

Title: Production of epitaxial wafer
Inventor: OI HIROYUKI
IPC: C23C16/24
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To prevent crack from being formed in a wafer by specifying the growth rate of an epitaxial layer so as to exist in a specific range when source gas is trichlorosilane and silicon tetrachloride. SOLUTION: The purpose of this invention is achieved by speeding up an epitaxial growth rate up to 2.5-5.5 μm/min and 2.5-5.5 μm/min when source gas is respectively trichlorosilane and silicon tetrachloride so as for epitaxial layer to be made to epitaxially grow on the surface of the wafer while feeding the source gas into an epitaxial growth oven. It is possible to prevent silicon grain from being formed on the outer periphery of the underside of the wafer and to prevent bridge from being formed by the flowing of source gas in the underside of the wafer from a gap between the outer periphery of the wafer and a susceptor and by the deposition and growth of silicon grain in the central part of the underside. Thus, the incidence rate of cracks in a wafer is reduced.

Title: Optical receiver device
Inventor: TETSUDO KAAKU UTSUDOWAADO
IPC: H04B10/43
Filed: 1994-11-18
Abstract: PURPOSE: To reduce the amount of static current in the receiver and power consumption by using a field effect transistor(EFT) to be driven by push-pull operation. CONSTITUTION: When light input beams A1 , A2 are respectively inputted to optical diodes 1, 4, positive gate-source power is applied to an FET 5 and negative gate-source power is applied to an FET 7. At this time, input beams B1 , B2 are dark. These input beams turn on the FET 5, turn off the FET 7, and during the switching phase, a current from the drain voltage upto the source voltage is allowed to flow until the FET 7 turns off, and the output of a node Z is stabilized, then a static current is no longer allowed to flow into the circuit. When the beams A1 , A2 are turned dark and the beams B1 , B2 turned light and inputted to optical diodes 2, 3, the FET 5 is turned off, the FET 7 is turned on, the output signal of the node Z is stabilized and a static current is not allowed to flow. Since the switching is operated by the push-pull operation of the optical receiver 10 and the switching time is short, power consumption can be minimized.
