Patent JP-H08166362-A (JP)
Title: Method and apparatus for analyzing surface
Inventor: ITABASHI NAOSHI
IPC: G01N23/225
Filed: 1995-04-18
Abstract: PURPOSE: To measure the element composition and bonding state of the uppermost layer at the surface of a solid with high sensitivity without damaging a ground, by separating multivalent ions to a predetermined number of valencies, decelerating the ions to a speed not higher than a sputtering threshold value of a material to be measured and emitting the ions to the solid sample. CONSTITUTION: When the multivalent ions are emitted after the kinetic energy thereof is sufficiently decelerated to not larger than a physical sputtering threshold value (generally not smaller than 20eV) of a solid, the ions do not invade the interior of the solid and particles (atomic ions) are emitted with a higher probability from the uppermost layer of the surface. Electron beams 107 are emitted to an Ar gas 106 at a multivalent ion-generating part 108, and multivalent ions 105 are taken out from the generated Ar gas 106 by a Wien filter 109. The kinetic energy of the ions is decelerated to not larger than 20eV by an ion decelerator 110 and emitted to an Si (100) substrate 101a. The distribution of the kinetic energy emitted from the surface is analyzed at 112.  In this manner, the element composition and bonding state of the sample surface can be measured with high sensitivity while damages are reduced.

Title: Lubrication structure of four cycle engine
Inventor: SUZUKI MASATAKE
IPC: F01M1/06
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To effectively utilize oil discharged from a crank chamber in the lubrication of a gear meshing part by providing a guide wall suspended on a meshing part side above a meshing part of a mission gear and an oil passage guiding oil discharged from one-way valve onto a guide wall side in a mission case. SOLUTION: A pressure in a crank chamber 34 fluctuates when a piston 21 of an engine for motorcycle reciprocates and slides, and a lead valve arranged in a swelled part in a bottom part of an engine case 31 is opened when the pressure in the crank chamber 34 increases to discharge oil in the crank chamber 34 onto a mission chamber 35 side. The discharged oil passes an oil passage 51 and is guided onto a guide wall 54 side suspended on a meshing part side above a meshing part of mission gears 45, 46 in a mission case 33. Consequently, since oil drops in the meshing part of the mission gears 45, 46 from the guide wall 54, lubrication of the meshing part is done effectively.

Title: Joining method for external parts
Inventor: SHIYOUJI SETSUO
IPC: B23K26/21
Filed: 1980-07-08
Abstract: PURPOSE:To improve the quality of joined parts and reduce costs by joining the adhering and joining parts of external parts by means of laser beam without using any intermediate member. CONSTITUTION:A part 2 and a part 3 are disposed by leaving a spacing 7. Laser beam 8 is irradiated to the center of the spacing 7 to partially melt the parts 2, 3, thereby joining these in the state of filling the spacing 7. In this case, if the spacing 7 is wide, the parts 2, 3 fail to make sufficient melting, resulting in the occurrence of black discoloration and imcomplete joining. It is therefore desirable to keep the spacing 7 at about <=0.1mm.. However, if the spacing 7 is too narrow, a projected part will be produced and therefore the joined part and the circumference thereof are made into a recess lower by one step than the other parts, so that the obstacles in assembling and meshing of other external parts owing to the formation of the projected part are eliminated.

Title: Photosensitive body and its manufacture
Inventor: FUJIMAKI YOSHIHIDE
IPC: G03G5/09
Filed: 1983-05-26
Abstract: PURPOSE:To enhance photosensitivity by incorporating a specified amt. of amine in an electrostatic charge generating phase. CONSTITUTION:A charge generating phase is formed by adding amine in an amt. of <20mol per mole of a charge generating substance into the coating solvent of the charge generating phase to disperse it into the solvent, and coating with the obtained liquid dispersion. As a result, said substance is not dissolved with the amine due to its presence of such a large amount during formation of a coat film, thus permitting a coating operation maintained in a dispersion state and enhancement of photosensitivity. The azo type pigments having remarkable effect of amine addition in the coating solvent of the charge generating layer are compds. represented by formulae I -III in which Ar<1>, Ar<2> are each an aromatic residue; R<1>, R<2> are each H or the like; (A) in formula I is a group of formulae IV; X is OH; Z is an aromatic ring or the like; A' is aryl; and (A) in formulae II and III is a group of formulae V.

Abstract: PURPOSE:To increase the stability and lifetime of discharge by a method wherein the end surface whereat the cylindrical metal as the anode has an aperture into the main body and a part of the internal surface of the cylinder which is continuous thereto are coated with noble metal, in a gas laser tube wherein the anode serves also as an exhaust tube. CONSTITUTION:The noble metallic layer 13 is that which mediates indium 14 acting as the cushion at the time of adhesion of the anode and exhaust tube 1 into the main body of the gas laser tube 2, and it is preferable to use Au, Pt, Pd, etc. which are stable even for the active gas such as oxygen. The noble metallic layer 12 is due to film formation by sputtering or ion-plating onto one end surface of the anode base body 11 made of an iron cylindrical metal and the surface of the discharge part composed of the internal surface of the cylinder which is continuous thereto, and the noble metal of the same kind as in the noble metallic layer 13 is used for it. The discharge area is wider, compared with the bar or projection anode, and then stable discharge can be obtained by being enabled to sufficiently correspond even to overcurrents and without the generation of defective conditions accompanied with the increase of temperature.
