Title: Gas concentration measuring method
Inventor: TANAKA YOSHIHISA
IPC: G01N21/3504
Filed: 1992-02-25
Abstract: PURPOSE:To measure even low concentration gas highly accurately by finding a linear equation of an operation value to an atmospheric pressure from two measurement values of gas concentration under plural different atmospheric pressures of not less than one atmospheric pressure. CONSTITUTION:Measurement gas is introduced into/substituted in a gas cell, and a discharge valve is closed, and a gas pressure is raised. When the pressure reaches a certain pressure A not less than one atmospheric pressure, the introduction is stopped, and outputs from an infrared sensor 5 are sampled, and an average value X is stored in a memory 21. In succession, the pressure is lowered to become pressures B and C not less than one atmospheric pressure, and the outputs of the sensor 5 are sampled respectively, and average values Y and Z are stored in memories 22 and 23. Last, the gas in the gas cell is substituted with air, and the output average value N is stored in a memory 24. Operations 27 are carried out respectively on values of X/N, Y/N and Z/N, and these values are stored in memories 29-31. Operations 32 are carried out on the two values X/N and Y/N among these values, and a specific linear equation is found. When an operation result obtained by substituting a pressure C in this equation coincides with the operation value Z/N, this equation, that is, concentration measurement by the sensor 5 is correct, so that an operation unit 35 can carry out an operation on concentration.

Title: Eye-ball position detecting device
Inventor: ICHINOSE SUSUMU
IPC: H04N13/04
Filed: 1988-04-11
Abstract: PURPOSE:To continuously observe a stereoscopic image without using special spectacles by conjecturing a position of both eyes which have moved from an interframe difference signal before and after the movement which follows up a movement of both eyes of an observer, and projecting a both eye image to this position. CONSTITUTION:A minute movement of a head part of an observer 8 is detected by a television camera 9, and information before and after the movement is stored in frame memories 11-1, 11-2. A difference extracting circuit 13 takes a difference of both the memories, and an apex A detecting part 14 detects the apex A of the observer 8 and informs its movement to a controller 15. The controller 15 conjectures the present position of both eyes from a both eye position which has been stored in an initial value memory 16 and the movement of the apex A and drives a projection machine driving mechanism 17. In such a way, by securing continuously a stereoscopic vision by tracking the movement of both eyes of the observer, a continuous stereoscopic image can be observed without using special spectacles.

Title: Motor
Inventor: HIRABAYASHI KOICHIRO
IPC: H02K13/00
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To prevent the surface of a commutator from being short of oil and prevent a brush and the commutator from being worn for attainment of high durability, by forming a recessed part at a position coming into contact with the brush of the commutator whose side surface is applied with lubricant such as oil. SOLUTION: This motor involves a brush contact surface 2 circumferentially- divided, disposed on the side of a commutator 1, and applied with lubricant such as oil to prevent a brush 5 from being worn because of friction during its rotation, wherein a recessed part (groove) 8 is formed in the brush contact surface 2. When the rotating shaft 3 of the motor rotates, the oil applied to the brush contact surface 2 moves in a rotational direction and is accumulated in the recessed part 8. It is thus possible to keep lubricating properties between the brush 5 and commutator 1, thereby preventing them from being worn.

Title: Spectrometer
Inventor: TAGAMI ICHIZOU
IPC: G01J3/26
Filed: 1980-06-30
Abstract: PURPOSE:To maintain the relation between wave lengths of spectral flux of radiation by a method wherein an incident flux of radiation is step by step separated into  its spectral components in terms of flux of radiation containing only the wave length which is the second degree of either one of interfering film filters transmitting the wave length of the second degree of the plural. CONSTITUTION:An incident flux of radiation 1 is condensed by a lens 3 to irradiate upon a position 17 on a cut-filter disc 5 via a collimating lens 6. The base wheel 8 of a Geneva wheel 10 is rotated by an electric motor 8, while a pin 12 is engaged with the engaging groove of a driven wheel 9 so that the driven wheel 9 is intermi- ttently driven. Simultaneously with the rotation of the driven wheel 9, a cut-filter disc 5 is driven and a cut-filter 4 is successively scanned in the irradiated position  17. On the other hand, an interfering film filter 18 is arranged in such a way that  the filter lies on top of the cut-filter 4. By so doing, the incident flux of radiation is  seccessively separated into the flux of radiation with the wave length of the second  degree of one, so that the relation between the wave lengths of the spectral flux of  radiation can be maintained with the same interfering film filter.

Abstract: PURPOSE:To analyze a contaminated metal with high sensitivity and further high quantity precision by a method wherein a FZ silicon crystal is used as a crystal for a contamination monitor in a silicon semiconductor manufacturing step. CONSTITUTION:After crystal-grown, sliced and ground in a CZ silicon wafer manufacturing step, a FZ crystal having the same size is set in the same step as CZ in a wafer washing step. Thereafter, after both wafers are taken out and heated at 600 deg.C for 30min. under pure environments below a dust degree class 10, a sample is dropped in a pump oil and promptly cooled. This sample is cut into 20X10mm and PL-measured at a liquid helium temperature. Letter a designates a PL spectrum of the FZ crystal, and b a PL spectrum of the CZ crystal. In the CZ crystal, only a peak caused by dopant impurities is observed, but in the FZ crystal, a characteristic PL peak is observed based on a copper except for the dopant impurities. Thus, it is possible to prevent defective products.

IPC: B41M5/52
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To realize the glossiness and transparency as that of photographic paper and improve dye ink absoptiveness by adding a graft copolymer having gelatin as backbone polymer in an ink adsorptive layer provided on a support. SOLUTION: The ink image-receiving layer of an ink jet image receiving body is formed of a graft copolymer whose backbone polymer is gelatin. The surface of the image-receiving layer containing the gelatin is not adhesive, whether an unprinted area or a printed area, and the gelatin has high strength of film. It absorbs water and swells. However, it does not dissolve in water at normal temperature. Using the gelatin having said good properties as backbone polymer and grafting various kinds of polymers as the second and the third components make it possible to give the ink image-receiving layer high absorbing performance while maintaining the properties of the gelatin, and obtain an image receiving body that has glossiness comparable to a silver-salt photograph, absorbs ink quickly, and dries the ink fast and is less adhesive.

IPC: G01C19/00
Filed: 1984-05-07
Abstract: PURPOSE:To perform high-precision detection even in case of temperature varies by winding an optical fiber around the peripheral surface of the drum counterclockwise and clockwise in crossing relation about the lengthwise center of the optical fiber as a center. CONSTITUTION:The optical fiber 8 is wound around the peripheral surface of the cylindrical drum 9 counterclockwise as an optical fiber 8L and clockwise as an optical fiber 8R about the center 8C of the optical fiber 8. In this case, the optical fibers 8L and 8R cross each other about the center 8C of the optical fiber 8, and consequently a temperature distribution is lengthwise symmetrical about the center 8C to cancel each other even when the temperature distribution on the drum 9 is difference between the upper and lower part. Therefore, there is no drift of the angular rotating speed of the drum, so the optical fiber gyro with high precision is obtained.
