Title: Apparatus for decomposing nitrous oxide
Inventor: MURATA MASAYOSHI
IPC: B01D53/74
Filed: 1988-10-25
Abstract: PURPOSE:To permit an easy decomposition of nitrous oxides in an unprocessed fluid into nitrogen and oxygen by generating glow discharge plasma between a flat plate electrode and a saw-toothed plate electrode by voltage application to activate the fluid with the plasma. CONSTITUTION:Opposite flat plate electrodes 100 are provided facing each of the upper and lower surfaces having sawlike notches of a flat plate electrode 101 and equally spaced from the latter electrode. The flat plates 102 made of a dielectric consisting of alumina porcelain, etc., are interposed between the electrodes 101 and 100 in contact with the latter. AC electric source 8 or pulse source is connected between the electrodes 100 and 101 to generate glow discharge plasma through which an unprocessed fluid is passed for activation, resulting in an easy decomposition of nitrogen suboxides in the fluid into nitrogen and oxygen. The flat dielectric plate 102 provided on the surface of the flat plate electrode 100 prevents a change from the glow discharge to the arc discharge.

Title: Optical recording medium
Inventor: SATO MITSURU
IPC: G11B7/24073
Filed: 1992-10-06
Abstract: PURPOSE:To obtain good reproduced signals by determining various parameters, such as groove shapes and recording film thicknesses, in such a manner that the depth of the recesses formed on the recording film of groove forming parts is kept within a prescribed range. CONSTITUTION:The tracking guide grooves, grooves 11 or prepits 15 are previously cut at a depth dg on a substrate 1 of the optical recording medium having a RAM type recording region or a ROM type recording region. The surface of this substrate 1 is coated with the recording film 2 and further, a reflection film 3. The recesses 21 of the depth df are formed in the groove 11 or prepit 15 parts of the film 2 and are set at df<=dg at this time. Then, an optical path difference arises in the optical path a of the recess 21 parts and the optical path b of the parts exclusive thereof. A phase difference is generated by the optical path difference. As a result, the recesses 21 are formed to the df within the ranges of equations I, II, respectively, where n0: the refractive index of the substrate 1 n1: the refractive index of the film 2, lambda: the wavelength of information reading-out light. As a result, the relation between the groove shapes, recording film thicknesses, etc., and the reproduced signal is optimized.

Title: Reverse gear noise preventing device for speed change gear
Inventor: IBUSUKI AKIRA
IPC: F16D23/12
Filed: 1993-09-30
Abstract: PURPOSE:To prevent generation of gear noise by disposing, in a shift and select shaft, a cam of which the top is engaged with or disengaged from a forward advance stage shift yoke, and pressingly energizing the cam toward an interlock plate side by a spring so as to cope with speedy operation to reverse shift. CONSTITUTION:When a select operation to the reverse is carried out, a shift and select shaft 86 is moved in the axial direction integrally with an interlock plate 88. At this time, the top of a cam 160 is moved to a position to be engaged with a first-speed and second-speed shift yoke 126. When a clutch is released and a shift operation to the reverse is performed, the shift and select shaft 86 is rotated so that the cam 160 is rotated in the same direction, thus pressing the first-speed and second-speed shift yoke 126 toward a second- speed counter gear. Subsequently, the cam 160 is rotated on a pin 170 by engagement of an inclined surface of the interlock plate 88 with an engaging projection of the cam 160, thereby released from the engagement with the first-speed and second-speed shift yoke 126 so as to perform reverse shift.

Title: Method for positioning container and for packing foodstuff and device for positioning container
Inventor: HIRAO OSAMU
IPC: B65B43/46
Filed: 1990-10-05
Abstract: PURPOSE:To achieve positioning with high accuracy by inserting a sucking drum through an opening of a container, holding the container by sucking force to rotate it, detecting a mark put on the container by a sensor, stopping the rotation of the container when it is turned in a predetermined direction and stopping the sucking to make the container free. CONSTITUTION:When a container 11 is provided, a sucking drum 24 is inserted into its opening. A solenoid valve 33 opens to effect sucking by means of a sucking device and hence the internal wall of the opening of the container 11 is attracted to the drum 24. Under such a condition, a motor 27 is actuated to rotate a hollow shaft 22. As a result, the drum 24 rotates and hence the container 11 attracted to the drum 24 rotates. A photosensor 35 detects a mark 37 applied to the surface of the container 11 and when it is confirmed that the container 11 is turned in a predetermined direction, a stop signal is sent to the motor 27 through a control panel 36 to stop the container 11. In such state, the valve 33 is closed to stop the sucking, so that the container 11 is released and caused to drop and is supported in a predetermined direction.

Title: Surface coated material applied with tin alloy plating and electronic parts utilizing the coated material
Inventor: TSUJI SEIKI
IPC: H01G13/00
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To increase the hardness of a lead-free tin alloy plating film. SOLUTION: In a surface coated material in which a tin alloy plating film of tin and at least one kind of metal selected from the group consisting of silver, bismuth, indium, zinc nickel, cobalt, copper and antimony is deposited on a base, the maximum value of the orientation property index calculated from the X-ray diffraction pattern of β-tin crystals in the plating film by a specified system is >=2, and the <001> orientation of the Miller indices in the β-tin crystals is orientated so as to make the angle of 0 to 40.8 degrees in the normal direction of the surface of the base. Since the <001> orientation of the β-tin crystals in the leads-free tin alloy film is orientated under the specific conditions in the normal direction of the surface of the base, even in the case deforming force along the surface of the base is caused, the sliding resistance of the above prescribed crystal plane increases, plastic deformation is made hard to occur, and the hardness of the film is increased to improve its wear resistance.

Abstract: PURPOSE:To absorb the vibration due to backlash between gears and the vibration on turning by connecting a driving gear with a steering shaft through a buffer member and a connecting member and fixing the buffer member onto the driving gear and the connecting member through baking process. CONSTITUTION:A motor pinion gear 5 is fixed onto the driving shaft of an electric motor 9, and a main shaft gear 3 is engaged with the gear 5 through a plurality of idler gears 4a and 4b. A connecting member, namely a torque transmission member 2 is connected to the main shaft gear 3 through a buffer member 1 nipped by the surfaces of the torque transmission member 2 and the main shaft gear 3. Said buffer member 1 is baked onto the torque transmission member 2 and the main shaft gear 3. Therefore, when the driving force of an electric motor 9 is transmitted to the torque transmission member 2, and a main shaft 8 is operated, the vibration due to the backlash between the gears can be absorbed by the buffer member 1.

Title: Forgery proof forms
Inventor: AIZAWA AKIFUMI
IPC: B42D15/10
Filed: 1993-09-30
Abstract: PURPOSE:To discriminate between a real form and a form forged by reproduction mechanically simply and cirtainly. CONSTITUTION:By printing parts of 'No. 12' and '67' in a train of the number of issue 3 of a merchandis bond 1 with infrared absorbing ink and printing a part of '345' therein with infrared reflecting ink, reflectance of both kinds of ink within an infrared area is measured with a spectrophotometer or the like. Since a difference between them is evident, three parts of the number of issue 3 can be discriminated. When the merchandise bond 1 is copied, since a copying machine copies by using a wavelength within the ultraviolet rays area or within a visible ray area, two kinds of reflectance in infrared area show same characteristics for an issue number 3 printed part of a copy. Further, when the number of issue 3 is printed with general ink, since the reflectance in the infrared area becomes of course a same one, the issue number 3 printed part becomes impossible to be discriminated by the difference in reflectance of ink, and can be judged as forgery.
