Patent JP-H07264354-A (JP)
Title: Image reader
Inventor: MAMIYA TOSHIHARU
IPC: H04N1/028
Filed: 1994-03-25
Abstract: PURPOSE:To prevent a lens unit supporting member from being deformed even if the supporting member and a sensor unit are fixed by adhesive by adhering the supporting member and a CCD holding sensor part by the surfaces with each other which are parallel to the optical axis of incident light on a sensor. CONSTITUTION:A lens base 11 and a lens unit 12 are fixed to an adjusting jig. A holding member 25 is made to about on the projection part 24-c of a fixing member 24 after the member 25 is fixed to the adjusting jig, and an optical adjustment is performed in the state. Because the space between the fixing member 24 and the holding member 25 is kept to a prescribed value as it is by the projection part 24-c of the fixing member 24 at a center part although force contracting solder is generated at this time and the force exerting between soldering parts 24-b and 25-b is in the roughly vertical direction to an optical axis at the center part, deformation is not generated in the both of the fixing member 24 and the holding member 25. At the both ends parts, deformation is apt to be generated, but because deformation is not generated at the center part and at an intermediate part, generated deformation amount is small. Thus, a color separation can be exactly performed for an original image.

Title: Pressure control valve
Inventor: NOZAWA YUUSAKU
IPC: F16K31/383
Filed: 1981-04-14
Abstract: PURPOSE:To improve an instantaneously operating characteristic of a valve without sacrificing a pressure override characteristic, by opening an outlet part of a relief oil passage to around a main valve flow outlet immediately after a valve seat flow out side for seating and unseating a main valve. CONSTITUTION:For a main valve 13 still under a closing state and a subvalve 18 immediatey after craking, a jet flow is not existent from the main valve 13, and pressure oil in a subvalve chamber 19 is relieved from a passage outlet 32 to a main valve flow outlet 7 through a discharge port 21 and oil passage 31, and returned to a tank from a tank port 3. Then immediately after craking of the main valve 13 by a difference of pressure applied between before and after the main valve 13, a main valve jet from a gap between a valve seat 12 and the main valve 13 never closes the passage outlet 32. If the main valve jet flow increases with an increase of valve opening of the main valve 13, the flow reaches an opening end of the passage outlet 32.

Title: Optical power generating element
Inventor: ISHIHARA TAKASHI
IPC: H01L31/04
Filed: 1987-03-11
Abstract: PURPOSE:To obtain a highly efficient amorphous solar cell which assures good conductive characteristic of carrier by controlling doping rate through employment of at least partial superlattice structure of the doped layer of amorphous solar cell. CONSTITUTION:The electrons of carrier generated at the non-doped layer 6 reach an n-type superlattice layer 13. In addition, holes of carrier generated at the adjacent non-doped layer reach the p-type superlattice layer 14. The electrons having reached the n-type superlattice layer 13 freely processed up to the p/n interface, since the conductive band is smoothly connected, by controlling the doping amount of phosphorus and the holes having reached the p-type superlattice layer 14 freely processed up to the p/n interface, since the valence electron band is connected smoothly, by controlling the doping amount boron. Therefore, recoupling of electrons and holes can be realized with excellent result.

Filed: 1992-02-06
Abstract: PURPOSE:To strengthen a Co- or Ni-based bonding phase and to obtain a TiC- based cermet alloy having both high strength and high toughness by specifying the Ti and Mo contents of the bonding phase. CONSTITUTION:This TiC-based cermet alloy consists of a TiC-based hard phase which may contain about 5-50vol.% WC added as necessary and a Co- or Ni- based bonding phase.
