Title: Optical switch circuit
Inventor: YAMAGUCHI TAKEHIKO
IPC: G02F1/335
Filed: 1982-08-25
Abstract: PURPOSE:To enable the constitution of a time divided optical selective switch circuit for multiple inputs and multiple outputs, by forming an optical waveguide of a plane type on a substrate of an optical integrated circuit thereby enabling the common use of the circuit as an optical path between input and output fibers. CONSTITUTION:The frequency of the high frequency AC electrical signal to be applied on a comb-shaped electrode is time dividedly and periodically changed to form a time divided multiple optical space switch. If an input light signal lambdai is the time divided multiple optical signal of a degree of multiplexing N consisting of time slots T1-TN, the frequency of the signal to be applied on the comb- shaped electrode is changed by each time slot time, then the input light of a specific input fiber is emitted to different output fibers by each time slot, whereby the optical switch equivalent logically to time divided multiple space switch is obtd.

IPC: A61B6/03
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To omit unnecessary data according to a photographing condition such as a photographing part for collecting, by selecting only an output from a detecting element an X-ray beam passing through a subject can be incident on when detecting elements the X-ray beam passing through the subject is incident on are limited. SOLUTION: At the time of photographing a head part, an inputting device 47 inputs a head part photographing mode and a controller 46 controls a digital adding circuit 37 and a signal selection circuit 38 to select the output of detecting elements enough for covering a valid area an X-ray passing through a head part is incident on in a direction within the slice surface of an X-ray detector 33. Then this mode sends data invalidates the circuit 37 to send data without being added to the circuit 38. At the time of photographing a stomach part, a stomach photographing mode is inputted to allow the controller 46 to control the circuit 37 to add the output of a detecting element at the same position in a direction within the slice face in the direction of a slice depth.

Title: Method and facility for storing and monitoring spent fuel
Inventor: MATSUDA MASAMI
IPC: G01M3/20
Filed: 1994-06-29
Abstract: PURPOSE:To highly accurately detect leakage gas without sampling by enclosing helium gas labeled by a small quantity of labeled gas in a sealing vessel and optically detecting the gas leaked into a housing tube from the sealing vessel by a sensor attached to the housing tube. CONSTITUTION:For instance, a sail quantity of carbon monoxide is enclosed in a sealing vessel 2 enclosing used fuel 1 as labeled gas together with helium gas of good heat conduction. In the case where a hole is opened in the sealing vessel 2 by corrosion or the like, helium gas containing carbon monoxide is leaked in the inside of a housing tube 3. Since carbon monoxide absorbs an infrared ray in the neighborhood of wavelength of 5.5mum and an absorption coefficient is very large, the infrared ray not exceeding the wavelength of 5.5mum is transmitted from a detection part 8 to a sensor 6. If a quantity of attenuation is measured in the inside of the housing tube 3, leakage can be detected in high accuracy. Thereby radiation leakage can be monitored in high accuracy without performing troublesome sampling.

Filed: 1980-10-22
Abstract: PURPOSE:To measure the velocity and direction of flow of slight fluid by detecting the movement of the ion layer produced in the fluid from the change in the electric field near an electric field generating electrodes in a measuring device for flow of fluid. CONSTITUTION:AC voltage is applied between the electrodes 50 and 51 disposed in underground water flow F, from an electric power source 60, so that an electric field is generated between the electrode plates. First, pulses are applied between ion generating electrodes 47 and 48, and a + ion P, a - ion Q and a bubble R are produced as shown in (A). Next, as shown in (B), the + ion and the bubble escape upward along a tapered part 44A, and the + ion approaches to detecting electrodes 49A, 49B, and therefore the conductivity between the electrodes increases and the voltage between the electrodes begins to drop. Next, when the + ion P comes to the intermediate of the detecting electrodes as shown in (C), the outut voltage of an ampofier 61 goes lowest. Velocity is obtained from the time since the generation of the pulse until the attainment of the lowest outut voltage and the distance between the electrode 48 and the intermediate point of the 49A and 49B.

Title: Magnetic recording medium
Inventor: KASHIWAKURA YOSHIHARU
IPC: G11B5/66
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium realizing high coercive force and low medium noise by enhancing the compatibility of a crystal lattice space on the interface between a Cr alloy undercoat layer and a Co alloy magnetic layer formed into a thin film. SOLUTION: This magnetic recording medium 1 is obtained by successively forming a Cr-Mo alloy undercoat layer 3, a Co alloy magnetic layer 4 and a carbon protective layer 5 in that order on a nonmagnetic substrate 1 by a sputtering method, wherein the compositional ratio of Mo in the Cr-Mo alloy undercoat layer 3 is made to 10 to 30 atomic %, and the film thickness of the Co alloy magnetic layer 4 is made to 15 to 25 nm. In the medium 1, since the crystal lattice space of the Cr-Mo alloy undercoat layer 3 is enlarged by the replacement of Mo to enhance the compatibility of the crystal lattice space on the interface between the Cr alloy undercoat layer 3 and the Co alloy magnetic layer 4, the crystal defects of the Co alloy magnetic layer 4 on the upper layer stacked up by an epitaxial growth can be reduced.  Thus, although the Co alloy magnetic layer 4 is a thin film having about 20 nm thickness, the objective magnetic recording medium 1 having high coercive force and low medium noise can be realized.

IPC: H01L29/78
Filed: 1991-06-20
Abstract: PURPOSE:To realize a high-speed MIS type FET with low power consumption by making the MIS type FET to be complementary to each other on the same substrate. CONSTITUTION:A junction section 4 constituted on a high-concentration p-type diffusion layer 2 and a high-concentration n-type diffusion layer 3 that are different in conductivity type is formed on the surface of a semiconductor substrate 1 composed of Si, etc. On the surface of the section 4 is formed a gate insulating film 5, of which the surface is provided with a gate electrode 6. The layer 2 is operated as a source S, and the layer 3 as a drain D, respectively. While a depletion layer formed in the section 4 is being operated as a tunnel area, the voltage is impressed to the gate G to operate a transistor while controlling the tunnel current. Therefore, high speed and low consumption can be realized. A vital condition is to prepare a p-n junction section composed of high-concentration and different-type impurities, thereby enabling to form the gate electrode on the p-n junction surface with the gate insulation film in between so as to form the MIS type FET.

IPC: H01L29/43
Filed: 1986-06-25
Abstract: PURPOSE:To inhibit electromigration effectively, and to obtain resistance strong even against mechanical stress by forming a metallic wiring in three layer structure. CONSTITUTION:A metallic wiring is constituted of first-third wiring layers 25-27, the metallic wiring consisting of the three layers is patterned through a photoetching method, and sintered (alloyed), and an oxide film 28 for protection is deposited on the metallic wiring. Since the first wiring layer 25 is shaped from aluminum to which silicon is implanted, junction breakdown with source- drain regions 23 as N<+> diffusion layers can be prevented in the same manner as conventional devices. Since the silicon concentration of the second wiring layer 26 is made higher than the first wiring layer 25 and the third wiring layer 27, a diffusion toward the first wiring layer 25 or the third wiring layer 27 from the second wiring layer 26 is promoted in silicon in aluminum. Accordingly, the segregation of silicon can be prevented.
