Title: Material inspecting apparatus for metal material
Inventor: OKUBO HIROYUKI
IPC: G01N29/00
Filed: 1994-10-11
Abstract: PURPOSE: To inspect a material accurate on-line by obtaining the propagating velocity of an ultrasonic wave in three or more different directions on the surface of a metal material, and deciding the material failure from the velocity difference from reference propagating velocities of the directions which have been previously obtained. CONSTITUTION: Transmitting elements 1-3 generate ultrasonic waves according to a signal from a pulser 4, and propagates them in the three directions on the surface of a steel plate, i.e., a passing plate (X) direction, a 45-degree (Y) direction to the plate and a (Z) direction perpendicular to the plate. Receiving elements 11-13 receive them, and send reception signals to arithmetic units 21-23. The units 21-23 measures time differences Tx -Tz between the signal of the pulser 4 and the signals of the elements 11-13, obtains speeds Vx -Vz of the Y, Y and Z directions from the distances between the elements 1-3 and the elements 11-13, and sends them to an arithmetic apparatus 30.  The apparatus 30 obtains the speed ratio of them to reference propagating velocities Vox -Voz of the respective directions thus obtained, compares them with the ratios, and judges abnormal when all are threshold values or less and normal except them.

Title: Arithmetic coding system
Inventor: SAITO MASAHIRO
IPC: H03M7/30
Filed: 1987-10-01
Abstract: PURPOSE:To reduce an arithmetic time by storing a predetermined coding table to a memory IC with respect to a change in the statistical property, and replacing the arithmetic processing for the readout of the table. CONSTITUTION:An ordient partial sum corresponding to each symbol is generated by a prescribed power approximation table. Then a symbol input is supplied to an arithmetic shift arithmetic section 50. The arithmetic section 50 adds the predetermined ordient and the partial sum generated newly when the symbol is predetermined state and inputs an extracted code series to a carry monitor section 51. The monitor section 51 monitors the coded series and inserts a control signal when a carry is generated. When the state above is consecutive, the address control signal is inserted and the carry monitor section 55 of a decoding section 40 excludes the said address. Then the monitor section 51 eliminate an undesired signal and sends the result to a decoding section 40 via a transmission line. The decoding section 40 applies the arithmetic operation required for the decoding by the arithmetic section 56 via the monitor section 55. The table is generated in advance to quicken the arithmetic processing.

Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To effectively use the light from a light source in a liquid crystal display device and to suppress decrease in the contrast due to external light. SOLUTION: The non-polarized light from a light source device 12 is passed through a linearly polarized light separation layer 32 and sub-dichroic linearly polarizing layer 15 to enter a liquid crystal cell 16. The direction of the director in the liquid crystal cell 16 is changed according to the application of the electric field so as to change the direction of the electric field oscillation vector substantially from 0 to 90 degrees. Then the light enters the surface dichroic linearly polarizing layer 18 and only the component having the polarization direction coincident with the polarizing transmission axis exits to the outside. The dichroic linearly polarizing layer 18 transmits 50% of the external light entering the layer and absorbs the rest of light.

IPC: B62D7/15
Filed: 1988-09-30
Abstract: PURPOSE:To provide variability for the cornering power of front and rear wheels by controlling the front wheel steering angle with a value obtained by adding a corrective steering angle pro rata with the front wheel sideways slip angle to the front wheel steering angle, and by controlling the rear wheel steering angle pro rata with the rear wheel sideways slip angle.

Title: Device and method for laser welding
Inventor: UIRIAMU II PIIRU
IPC: B23K26/08
Filed: 1994-09-13
Abstract: PURPOSE: To provide the system and method for properly laser-welding an inner surface of a repair sleeve disposed in a heat exchanger tube of a steam generator. CONSTITUTION: This system uses a laser that generates a laser beam with an intensity sufficient to fuse a sleeve 210 to the inside diameter of a heat exchanger tube 50. A fiber-optical cable 230 is optically coupled to the laser for conduct a laser beam therethrough. The optical fiber cable has a predetermined configuration to homogenize the laser beam so that the laser beam obtains the desired spatial coherence as the laser beam is emitted from the fiber-optical cable. A reflection mirror 240 is optically coupled to the fiber- optical cable so as to receive the homogenized light beam emitted from the cable. The reflection mirror is also optically coupled to the inner diameter of the sleeve for reflecting the homogenized light beam onto the inner diameter to weld or fuse the sleeve to the inner diameter of the heat exchanger tube.  Thus, the heat exchanger tube is repaired by welding the sleeve to the inside diameter of the tube.

Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To nullify undesired signals in a communication signal at a large number of individual and separate valid arrival areas by applying weighting and adjustment to a beam shaping network in response to the undesired signal. SOLUTION: A 1st stage, that is, 1st set of beam shaping network (BFN A-H) 26 is subject to static weighting ad adjustment by a controller 31 to provide an open loop or a valid arrival pattern to a concerned theatre.

Title: Pulse generating circuit
Inventor: ONO HIDEYUKI
IPC: H04N3/14
Filed: 1984-11-26
Abstract: PURPOSE:To drive a load independently of the capacity of load by providing a DC voltage drive MOS-Tr switched by an output pulse to an output terminal to drive the load capacity by a DC voltage. CONSTITUTION:A pulse is outputted to the output terminal by sing outputs 2, 6 obtained at a conventional scanning pulse generating circuit surrounded by dotted lines to make MOST T10, T12 provided newly conductive. In this case, in order to increase the W/L (=gate width/gate length) of the MOST, the gate width W is increased causing a parasitic capacitance between the drain and gate to be increased, but since a DC voltage is fed to the drain of the MOST T10, T12, the increase in the gate voltage of the MOST due to bootstrap effect is not caused. Thus, in selecting the MOST T10, T12 having the W/L in matching with the load capacity, a large load capacity is driven.

An expression vector pAKK0- hMe1R7 having a DNA coding for a human melatonin receptor protein is obtained by integrating the DNA coding for a human melatonin receptor protein having the base sequence expressed by the formula into a vector. Subsequently, the expression vector is introduced into a CHO cell deficient in a DHFR gene to transform the cell. The transformed cell is cultured under conditions in which the genes can be expressed to obtain the objective protein useful as a prophylactic or a treating agent for prostatic carcinoma, uterine cancer, benign prostatic hypertrophy, myoma of the uterus, etc., a pregnancy-controlling agent, etc.
