IPC: C23C14/06
Filed: 1993-03-15
Abstract: PURPOSE:To modify the surface of a material by ion implantation and to improve the corrosion resistance. CONSTITUTION:Ions (a) are implanted into the surface of a base material (d) in an oxygen atmosphere to form a region (e) having a high concn. of the implanted ions near the surface of the base material as well as to form an oxidized coating film (f) in the surface of the base material.

Title: Electrophotographic sensitive body
Inventor: KOJIMA AKIO
IPC: G03G5/00
Filed: 1984-03-21
Abstract: PURPOSE:To improve electrophotographic characteristics and mechanical characteristics by forming an undercoat layer made of a specified resin between a conductive substrate and an electrostatic charge generating layer and dispersing a charge generating material into a specified binder resin to form said charge generating layer. CONSTITUTION:A photosensitive body is formed by successively laminating an undercoat layer composed essentially of a nylon resin, a charge generating layer (CGL) using a phenoxy resin represented by the formula shown here as a binder resin, and a charge transfer layer (CTL) on a conductive substrate. The formation of the undercoat layer made of an alcohol-soluble nylon resin alleviates the roughness of the surface of the substrate, and permits a uniform CGL to be formed. The nylon resin has good adhesion to the substrate, and prevents injection of opposite charge from the substrate. The use of the phenoxy resin as the binder of CGL permits its OH groups to act as adsorption sites, dispersion of a charge generating material to be improved by an small amt. of said resin, and a uniform and thin CGL to be formed.

Title: Corrugated waveguide or horn
Inventor: SUZUKI YASUO
IPC: H01Q13/02
Filed: 1984-03-23
Abstract: PURPOSE:To improve the VSWR characteristic over a broad band by producing two parameters relating to the propagation of an electromagnetic wave in the direction of the depth of corrugated slot. CONSTITUTION:A dielectric substance 24 is provided to a part including a bottom part 25 of the corrugated slot 23, but not provided to an inlet 26 of the slot and then a wall face 27 of the opening is exposed. Since the dielectric constant differs between the dielectric layer and the air layer in the direction of the depth of the slot 23 in this way, two kinds of parameters with respect to the propagation of an electromagnetic wave are produced. As a result, a capacitive susceptance having the slot 23 is used for a wider band and when the corrugated waveguide 21 is used as a mode converter, the frequency characteristic excellent in the standing wave ratio is widened so as to utilize the characteristic of the corrugated horn.

Title: Runner joint of water turbine or pump water turbine
Inventor: SHINOHARA MORIMICHI
IPC: F03B3/12
Filed: 1979-05-04
Abstract: PURPOSE: To simplify the structure of a runner joint by a method wherein a built-in friction joint is provided in the space between a tube-like boss formed on the same body with the joint flange of a runner and the outer periphery of a main shaft in the junction between a turbine runner and the main shaft.  
     CONSTITUTION: On the side of inner pheriphery of a water turbine runner 1, a tube-like runner boss 7' is formed on the same body with a runner flange 7, while a built-in friction joint 8 is provided in the space made by the inside-diameter surface A of the runner boss 7' and the outer-periphery surface B of a main shaft 2. The rotational torque of a runner 7 is thereby transmitted to the main shaft 2. A pressure plate 9 is fastened tight to the runner boss 7' by a bolt 3', thereby the infiltration of water in the friction joint being prevented, and further the runner flange 7 and the main shaft 2 are fastened directly by a bolt 3, thereby the runner 1 being fixed to the main shaft. In this way, the form of junction of the runner and the main shaft is simplified and a flange in the lower part of the main shaft becomes unnecessary, which makes it unnecessary to consider any bad order to be caused by the concentration of stress on the joint of the flange.

Title: Lead frame
Inventor: ACHINAMI MASAYOSHI
IPC: H01L23/50
Filed: 1988-03-08
Abstract: PURPOSE:To load a larger-sized semiconductor chip on a resin-seal type package of the same size as conventional packages by diminishing the volume of a die pad and reducing stress by providing a recessed section to the die pad while increasing the drag of a resin by thickening the resin in the recessed section. CONSTITUTION:A recessed section 9 is shaped on the side reverse to a surface, on which a semiconductor chip is placed, in a die pad section 2 in a lead frame used for a resin seal type semiconductor package. The die pad 2 is formed in structure in which the recessed section 9 is shaped to the surface, on which the semiconductor chip is not placed, through etching, etc. The peripheral section 10 of the die pad 2 is not thinned because trouble such as bending due to insufficient strength on assembly working must be avoided. Symmetrical shapes to the center lines X-X', Y-Y' of the die pad of the recessed section 9 are preferable for preventing the local concentration of stress.
