Title: Grasping method of displacement mode by holography interference method
Inventor: OOTA HIROSHI
IPC: G01B9/021
Filed: 1984-06-20
Abstract: PURPOSE:To determine the degree automatically by setting the light emission of a primary pulse on the basis of the dynamic response characteristic of a body to be measured, and performing image operation while aiming at the movement of interference fringes of the same degree with time on the basis of images obtained while delaying the light emission of a secondary pulse successively. CONSTITUTION:When a cantilever oscillates in tertiary elastic mode, the time of primary exposure is fixed to constant time t0, the secondary exposure is carried out at optional time intervals DELTAt1 and DELTAt2 from t0 to record a double exposure hologram, and the time interval DELTAt2 is so set that the movement extent of interference fringes of the same degree is a half minimum interference fringe intervals for an interference fringe density distribution of images of DELTAt1. Then, a fringe image is processed to obtain line images (b) and (c). Further, the correspondence between the closest interference fringes with the time intervals DELTAt1 and DELTAt2 is determined and the movement direction (arrow) of interference fringes of the same degree are coded into + or -1. Further, there is a node in an area where the loop of oscillation changes from -1 to +1 in an area of a change in sign from +1 to -1, and the degree is determined automatically.

Title: Electron gun for color image receiving tube
Inventor: SHISHIDO AKIRA
IPC: H01J29/48
Filed: 1989-05-19
Abstract: PURPOSE:To raise resolution and improve display quality by a method wherein constant focusing voltage EC3 is applied to a first focusing electrode and dynamic voltage EC3' for offsetting distortion of electron beam shape due to a deflected magnetic field is applied to a second focusing electrode so that EC3>EC3' is satisfied at the center of a screen. CONSTITUTION:Constant focusing voltage EC3 is applied to a first focusing electrode and dynamic voltage EC3' for offsetting distortion of electron beam shape due to a deflected magnetic field is applied to a second focusing electrode so that dynamic EC3' is dynamic voltage wherein EC3>EC3' is satisfied at the center of a screen 41. Therefore electron beam is deflected toward a screen periphery 42, a value of EC3'-CC3 is small so that the shape of electron beam at a main electron lens is an approximately circle to reduce influence due to spherical aberration of the main electron lens and largely improve the focus level especially in the periphery of the screen. Thus an electron gun for a color image receiving tube high in resolution and excellent in display quality can be obtained.

Title: Manufacture of oxide superconducting wire
Inventor: FUJIGAMI JUN
IPC: C01B13/14
Filed: 1993-05-27
Abstract: PURPOSE:To provide an oxide superconducting wire having an improved critical current density by filling oxide superconducting powder or material powder inside a metal sheath, followed by repeating plastic working and sintering twice under a specific condition. CONSTITUTION:After oxide superconductor powder or material powder is filled inside a metal sheath, plastic working and sintering are repeated twice, thus manufacturing an oxide superconducting wire in the following process. In sintering, a first sintering time is set to 20-75 hours, and a second sintering time is set to 75-150 hours. In the case where plastic working and sintering are repeated plural times in manufacturing a superconducting wire, first sintering seems to be contributive to formation of a superconducting phase. After the first sintering, plastic working is applied in order to mechanically improve orientation of crystal. Second sintering onwards after the plastic working are contributive to enhancement of mutual binding of crystal grains, which are improved in orientation by the plastic working, i.e., improvement of a weak binding grain boundary.

Title: Head for measuring reflectivity
Inventor: YURUGEN BARII
IPC: G01N21/47
Filed: 1983-07-13
Abstract: The present invention is with respect to a reflectance measuring head that is designed for stopping the production of false readings by regular (as opposed to diffuse) reflection and shiny parts of the sample without using normal shine traps or diaphragms. False readings as produced by regular reflection, by surface grain or structure and by inhomogeneity of the surface of the sample are furthermore put an end to by having a number of transmitters placed at an equal distance from one receiver or having a number of receivers placed at an equal distance from a transmitter. A more specially useful effect is produced if a number of transmitters and a number of receivers are placed alternately in the form of a matrix.

Title: High-frequency transistor power amplifier
Inventor: SUGIURA SADAHIKO
IPC: H03F3/21
Filed: 1978-10-13
Abstract: PURPOSE:To eliminate a higher harmonic sufficiently by providing an end opening transmission line filter, which is short-circuited for the higher harmonic, in the output side. CONSTITUTION:In case the length l of end opening stub 26 provided on the transmission line is l<1/4 wave length, the stub is capasitive; and in case of l=1/8 wave length, the susceptance of stub 26 is equal to the characteristic admittance of the transmission line which stub 26 has. Then, matching in the output side can be taken by changing the characteristic admittance by changing the line width of stub 26. Meanwhile, the 1/8 wave length line for the fundamental wave becomes 1/4 wave length for the second higher harmonic, and the susceptance which stub 26 has is infinite. Consequently, stub 26 operates as a removal filter for the second higher harmonic. A 1/12 wave length stub is used for the third higher harmonic. Further, this unit is made into a MIC, and plural stubs are provided, so that it becomes small-size and can be operated efficiently.

Title: Production of vinyl chloride polymer
Inventor: HIRAMATSU KEN
IPC: C08F2/20
Filed: 1997-05-16
Abstract: PROBLEM TO BE SOLVED: To provide a process whereby the time necessary to supply feeds can be shortened, and the time efficiency of polymerization can be improved, which process comprises feeding an aqueous solution of a polymeric suspension/ dispersion stabilizer into a polymerizer, deaerating the feed, starting feeding previously deaerated warm water and a vinyl chloride monomer simultaneously or in such a manner that the feeding of the warm water precedes that of the monomer somewhat and introducing an oil-soluble initiator into the vinyl chloride monomer line via an exclusive metering line simultaneously with the start of monomer feeding. SOLUTION: The water-soluble or water-dispersible polymeric suspension dispersion stabilizer used is a combination of a partially saponified polyvinyl acetate, methylcellulose or the like with polyethylene oxide. The time from the start of feeding the previously deaerated warm water to the start of feeding the vinyl chloride monomer should be within 2 min. Although the time taken to feed the oilsoluble initiator is not particularly limited, it is desirably within 40%, of the total feed time. This process can provide a vinyl chloride polymer reduced in the tendency to form fish eyes and markedly improved productivity.
