Title: Heat resistant and corrosion resistant silver plating material
Inventor: KODAMA ATSUSHI
IPC: C25D5/12
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To suppress the increase of contact resistance in the subject material even in the use for a long time in a high temp. environment and to improve its corrosion resistance by composing it of an intermediate layer of alloy plating contg. a specified amt. of P, and the balance Ni with inevitable impurities or contg. Ni and Co with inevitable impurities and an Ag or Ag alloy plating surface layer. SOLUTION: The content of P in the intermediate layer is controlled to 0.05 to 20 wt.%. P diffuses from the intermediate layer into the Ag plating and moreover into the Ag surface by heating to form a film of phosphorous oxide or phosphate. The film suppresses the corrosion of the plating caused by sulfide as a protection film without increasing the contact resistance of the plating surface and moreover suppresses the oxidation of the boundary between the plating and the intermediate layer. Ni or Co in the intermediate layer is a base metal for introducing P into the intermediate layer and moreover has the operation of preventing the phenomenon that Cu diffuses into the plating and is oxidized to increase the contact resistance. The thickness of the intermediate layer is preferably controlled to 0.5 to 3 μm.

IPC: F04C29/00
Filed: 1994-07-26
Abstract: PURPOSE:To prevent generation of any seizure of a slide part at the time of operation restart after operation stop for a long term by providing lots of minute oil sumps which can store lubrication oil on a contact slide surface with a partner member for at least one of each end place, thrust bearing, selfrotation obstruct mechanism, etc., of fixed and turning scrolls. CONSTITUTION:In a scroll type compressor formed by meshing a fixed scroll with a turning scroll 2 in each of which a scroll shape lap 21 is installed in one body to each end plate 22 by shifting their phases, lots of minute oil sumps (recessed parts) 100 are formed on the back surface of the end plate 22 of the turning scroll 2, namely on the surface sliding in contact with a thrust bearing. These oil sumps 100 are favorably formed as recessed parts with about 50mu diameter and 20-30mu depth. Thereby, as lubrication oil can be kept in the minute oil sumps 100, even after operation stop for a long term of a scroll hydraulic machine, seizure may not take place between the thrust bearing and the end plate at the time of operation restart so that favorable slide can be guaranteed.

Title: Second harmonic generating light source of waveguide path type
Inventor: ITOU AKITOMO
IPC: G02F1/37
Filed: 1993-07-14
Abstract: PURPOSE:To provide a second harmonic generating light source which involves less deterioration in the efficiency for varying laser wavelength, is easy to conduct light collection, provides less wave-front abberation, and is easy manufacturable, by furnishing a plurality of polarized inversion/refractive index modulation parts having different periods. CONSTITUTION:A second harmonic generating light source of waveguide path type includes a light waveguide part 4 composed of at least two regions having different periods, with which a semiconductor laser 7 makes oscillation with a wavelength meeting Eq. I by Bragg's reflection from the region with a period LAMBDAl where the light waveguide part 4 exists, and setting is made so that at least one of modulation periods LAMBDA2 other than this region meets Eq. II and does not meet Eq. I. In Eqs., N(lambda) is the effective index of refraction of the waveguide light at wavelength A and N(lambda/2) is the refractive index of the waveguide light at the wavelength lambda/2. Because one of them is used for generation of second harmonic while the other is used as a diffraction lattice, the second harmonic generating part can be provided separately from the reflection part of the fundamental wave, so that an optimum design can be made for respective conditions.

Title: Alarm switch operating device for circuit breaker
Inventor: OZAKI SEISHIROU
IPC: H01H71/04
Filed: 1989-07-06
Abstract: PURPOSE:To provide possibility of easy fitting of a plurality of alarm switches without impairing the insulation effect by rotating a cross bar with the aid of a latch receptacle further from the trip position with rotation of latch at the time of tripping motion, and by operating the actuator for the alarm switch with this cross bar.

Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire wherein workability of attachment to the ceiling can be improved and an attached state to the ceiling can be stabilized. SOLUTION: A fixing metallic part 32 is connected to a luminaire body, swung and held by a hanging bolt 23 on the ceiling via a nut 25.

Abstract: PURPOSE:To perform further easily and surely setting confirming a dividing point by reproducing a sound after and before the sound is divided and set for a prescribed time, while generating a discriminating sound at a dividing point. CONSTITUTION:An operator can confirm the end of a paragraph with a cursor moving on a sound volume level waveform and a sound actually reproduced from a loudspeaker 12, a dividing switch of an input device 17 is pressed at the end of a paragraph and the like to be divided into a reproduced sound. Thereby, a dividing point is set. Thus, when the dividing point is set, a computer reproduces a sound of approximately one before the dividing point, generates a deep sound at the time of reaching the set dividing point, and informs the operator of a position of the set dividing point. Further, after the computer reproduces the sound of a approximately one second after the dividing point, returns a cursor of a monitor 19 to the dividing point. Thereby, since computer 15 reproduces sound before and after the set dividing point, the dividing point can be obtained.

IPC: C25D5/30
Filed: 1992-07-02
Abstract: PURPOSE:To provide a method for manufacturing a Zn-Cr alloy electroplated Al sheet excellent in overall performance required for an automotive material such as chipping resistance, corrosion resistance after coating or the like.

Title: Solid electrolyte type electrolytic cell fuel electrode material
Inventor: SUMI MASAO
IPC: H01M8/02
Filed: 1993-07-15
Abstract: PURPOSE:To enhance the performance while preventing coagulation, by mixing with each other in the state of a salt solution the electrode constituent elements such as, for example, nickel, zirconium, and the like and thermally decomposing the resulting solution. CONSTITUTION:Nickel, zirconium, ittrium, and the like which are constituent elements of an electrode are mixed together on an atomic basis in a salt solution, i.e., in a state where each element is in a condition of solution and exists in the form of ion. By thermally decomposing the resulting mixture so that the mixed elements do not separate from each other, a powdery body of an oxide in which each element is uniformly mixed on an atomic basis is obtained. In this case, a granular material having a granule size of 5mum or more is sintered in which nickel, zirconium, and ittrium obtained by thermally decomposing the mixed solution are mixed together on an atomic basis. As a result, since the respective elements are dispersed on an atomic basis, nickel is difficulty coagulated during the operation whereby it is possible to prevent the degradation of the performance and also to enhance the performance of the electrode owing to resultant increase in the three-phase interface of nickel, solid electrolyte, and gas phase.

Title: Parallax adjusting mechanism for finder
Inventor: OGAWA YUKIO
IPC: G03B13/14
Filed: 1988-07-14
Abstract: PURPOSE:To excellently adjust the parallax of a finder which often occurs at the time of macro-photographing by utilizing a movable reflecting member for switching an eye level and a waist level. CONSTITUTION:In the case of performing observation at a waist level, a switching means 10 is operated in a direction shown by an arrow Q so that a holder 9 turns clockwise centering around a supporting shaft 9a and abuts on a stopper 12b to be held by a clipper spring 11. At such a time, a finder system at the waist level can be formed by an optical path combining points A-C in the optical path and a finder image can be observed through an eyepiece lens 3. Next, when a switching operation member 12 is operated in a direction shown by an arrow R in order to switch to a macro-photographing mode, the member 12 is held on a position where a flat spring 14 for clipping is plunged into a V-shaped groove 12C. Therefore, the stopper 12b moves upward and a reflecting member 8 finely turns cunterclockwise centering around the supporting shaft 9a, whereas an object positioned downward can be observed by an eyepiece lens 3.
