Title: Passive type infrared sensor
Inventor: KONISHI YOJI
IPC: G01J5/34
Filed: 1989-02-23
Abstract: PURPOSE:To make the detection sensitivity nearly uniform irrelevantly to the angle of incidence of heat rays by using a unflat surface as the detection surface of a heat-ray detecting element for detecting the heat rays. CONSTITUTION:The heat-ray sensing element 6 is formed by putting a couple of pyroelectric elements 6b in a package 6a. The element 6b is formed by sticking a pyroelectric layer 6e on the surface of a base 6d. The layer 6e is stuck on the base 6d in a surface parallel to a filter 6c and surfaces perpendicular to the filter 6c, i.e. three surfaces in total. The element 6b has structure like this and three detection surfaces S are therefore obtained. The photodetection energy A on the detection surfaces for the heat rays depends upon the angle thetaof incidence of the incident heat rays; and the maximum sensitivity is obtained when theta 45 deg., the sensitivity is made more uniform than when only one detection surface S is formed, the directivity becomes weak. Here, the three detection surfaces S are provided, but when five surfaces are provided or the base 6d is shaped except in the shape of a rectangular prism, desired sensitivity characteristics are obtained.

Title: Color rendering property control device for high pressure sodium vapor lamp
Inventor: KICHISE HIDEO
IPC: G01J3/51
Filed: 1982-03-19
Abstract: PURPOSE:To measure simply the color rendering property of a high pressure sodium vapor lamp by obtaining luminescence energy ratio of the lamp in two wave length ranges. CONSTITUTION:The light from a high pressure sodium vapor lamp 13 passes through a filter with wave length of 590nm at center with transmission band with half value width of 5nm on both sides and directed to a photoelectric transducer element 2, and its output I1 is input to a divider 6. On the other hand, the light from the lamp 13 passes through a filter 3 with transmission bands which have lambda1-lambda6 wave lengths as centers with half value width of 5nm by 5nm interval in the range of 560-585nm and received by a photoelectric transducer elements d1-d6, and their outputs are inputted to a maximum value detector 5, and the maximum value I2 in them is sent to a divider 6, where I2/I1 is calculated. Output I2/I1 is compared with an upper limit reference value V01 and a lower limit reference value V02 respectively from reference voltage generating devices 7 and 9. If V02<I2/I1<V01 is determined by a judgement device 11, that is, it is judged that the outputs I1 and I2 are within the range of color rendering control, the lamp 13 is lighted. The color rendering property is thereby judged simply.

Title: Exhaust gas emission control device for internal combustion engine
Inventor: ISHIYAMA SHINOBU
IPC: F01N3/08
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve the NOX purification efficiency of an NOX occlusion reduction catalyst. SOLUTION: An NOX occlusion reduction catalyst 7 is arranged in the exhaust passage 3 of an engine 1 to absorb NOX contained in exhaust gas of an engine under lean air-fuel ratio operation. When an NOX occlusion amount of the catalyst 7 attains a predetermined decision value, a reducing agent (diesel oil) is injected in an exhaust passage on the upper stream side of the catalyst 7 through a reducing agent feed nozzle 91 and NOX is emitted from the catalyst 7 for reduction purification. The decision value is set such that an emission amount of unpurified NOX due to exudation under absorption of NOX is decreased to a predetermined low value.  This constitution, since emission of unpurified NOX through discharge or exudation owing to the increase of an occlusion NOX amount is suppressed to a low value, remarkably improves the NOX purification efficiency of the whole of the NOX occlusion reduction catalyst.

Title: Magnetic recording medium
Inventor: KOSHO NOBORU
IPC: G11B5/72
Filed: 1985-03-07
Abstract: PURPOSE:To obtain a magnetic recording medium on which an excellent surface protective film having good adhesiveness, lubricating performance and rust preventive power in combination is formed with good reproducibility by providing the surface protective film consisting of the inorg. compd. and fluoropolymer deposited simultaneously by sputtering on a thin magnetic film. CONSTITUTION:The inorg. compd. as a component having surface hardness and the fluoropolymer as a component having excellent lubricating performance are formed by simultaneous sputtering as the surface protective film. The surface protective layer in which the inorg. compd. and the polymer are extremely microscopically compatible with each other is thus formed to a uniform thickness. The fluoropolymer is formed as the composite layer in this protective film and therefore the adhesiveness to the magnetic film consisting of gamma-Fe2O3, etc. is remarkably improved and the abrasion loss by the sliding with a magnetic head or the migration of a large amt. to the head is prevented. The improvement in the rust preventive power of the thin magnetic metallic film contg. Co, Ni, etc. is resulted by the incorporation of the fluoropolymer having excellent water repellency into the protective film.

Abstract: PROBLEM TO BE SOLVED: To pull back a pipe jacking body while contriving the damage protection of the pipe jacking body and the safety maintenance of a working environment by setting the retreat limit of the rear end position of the pipe jacking body on the receiv ing base of the pipe jacking body and obstructing retreat on and after the retreat limit. SOLUTION: When a pipe jacking body 20 is pulled back, a receiving base 7 is pushed back in the case where the rear end 22 of the pipe jacking body 20 is brought into contact with the locking body of the receiving base 7 of the pipe jacking body until it reaches the end point of a pull back stroke. Furthermore, a retreat limit 10 operates a retreat limit switch 15 positioned on a retreat limit L, and the retreat operation of a drive mechanism 3 is stopped. The sandwiching of the pipe jacking body 20 is opened, the drive mechanism 3 is advanced and operated to advance a clamp mechanism 2, and, if the interconnection of the pipe jacking body 20 is released, it can be shifted to a next pull back process.  Thus, the retreat limit L is prevented from pushing for the rear side wall part of the pit P of the pipe jacking body 20, and an interval is provided to be set between the pipe jacking body and the rear side wall part 34. Thereby a worker can be protected from such an accident that he is caught between the pulling back pipe jacking body 20 and the rear side wall part 34.

Abstract: PURPOSE:To promote formation of optical fibers having excellent transmission characteristics and high mechanical strength, by drawing a wire so as to provide a constant fluctuation range of a wire diameter of a drawn optical fiber before coating a resin liquid. CONSTITUTION:A fiber 3 drawn into a wire by applying tension to a heated and melted optical fiber preform is coated with a resin liquid 4 and cured to prepare an optical fiber.

Filed: 1986-03-04
Abstract: PURPOSE:To obtain the titled optical recording medium having excellent photosensitivity to a semiconductor laser beam and capable of being reversibly recorded by using an amorphous alloy consisting of iron and tellurium and wherein the content of tellurium is specified as the recording medium. CONSTITUTION:When Te having strong absorptivity to semiconductor laser light is added by extremely small portions to Fe of a polycrystalline substance in an amorphous alloy shown by the formula Fe100-xTex (where, x is atom%), the Te intrudes into an Fe lattice which is strained and the structure is changed in accordance with the content of Te. Namely, at <=about 7% (x), the alloy is a solid soln. and a transition region having a crystal structure wherein amorphous structures are scattered is formed at >7% (x). When (x) is increased to 12%, the lattice is remarkably strained and an Fe-Te amorphous alloy is obtained at least at >=14% (x). Besides, a transition region is similarly formed at >90% (x). When the Te content is increased from 14%, an amorphous structure is maintained and the photosensitivity to light is generated by Te in the solid soln. However, a semiconductive alloy is formed by Te in the transition region at >=90%.
