Title: Portable telephone system
Inventor: OKADA SHIGERU
IPC: H04B7/26
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To attain communication in a train without increasing power consumption of a portable terminal without modification of a portable telephone set. SOLUTION: A portable telephone base station 1 is located in a train and a zone connected to a portable terminal 6 is formed in the train. The portable telephone base station 1 is connected to an existing train telephone exchange 2 via a controller 3. The controller 3 matches the transmission capacity of the portable telephone system with a transmission capacity of the existing train telephone exchange 2 and rearranges connection protocol data from the portable telephone base station 1 to inform a destination dial number to a private telephone line so as to match dial information and a voice signal between the existing train telephone exchange 2 and the portable telephone base station 1. In this case, since the portable telephone base station 1 moves with the portable terminal 6, a coverage area of the portable telephone base station 1 is not relatively changed. Then high speed mobile communication of the portable terminal 6 is attained with the power consumption equal to that of a conventional system.

Title: Apparatus for substituting gas in drink container
Inventor: FURUSAWA YUJI
IPC: B65B31/04
Filed: 1995-06-06
Abstract: PURPOSE: To efficiently substitute residual air in a drink container with a substitutional gas by providing a branch for dividing gas to right and left at the center of a passage on a part where a gas passage connects to an arc recess, forming nozzles on right and left of the branch and specifying shapes of the respective nozzles. CONSTITUTION: When air remaining in a space 7 in an upper part of a container 3 is to be substituted with substitutional gas 6, the substitutional gas 6 is blown out from both openings of a gas nozzle 2 by approximately equal amounts. At this time, the respective nozzles 2 are formed in such an angle that flows of the substitutional gas 6 from the nozzles 2 collide with each other at the center of the container 3. Although the flows from right and left which have collided at a part indicated by dotted lines attempt to advance reversely, since a lid 4 exists above them, they flow to enter the space 7 in a lower part of the container, and after they pass inside the space 7 while pushing out residual air in the space 7, they are discharged outside. Thus time required for gas substitution and an amount of the substitutional gas can be largely reduced.

Title: Method for measuring diameter of crystal grain by ultrasonic wave
Inventor: SEKIGUCHI SHIYOUICHI
IPC: G01N29/00
Filed: 1983-08-01
Abstract: PURPOSE:To measure the diameter of the crystal grain of a steel material quickly and highly accurately, by clearly defining the diameter of the crystal grain by the concept of the effective crystal grain, and determining the expressions for computing the diameter of the crystal grain by using the measured value of an attenuation constant from the viewpoint of actual utilization of the measuring method. CONSTITUTION:An ultrasonic wave emitted from an ultrasonic wave vibrator 2 is multiply reflected between both surfaces 11 and 12. The sound-pressure-echo train is detected by the vibrator 2. Then the sound pressure P of the echo is attenuated approximately exponentially with respect to a propagation distance X, and can be expressed by P=P0e<-alpha>X. An attenuation constant alpha(dB/cm) is defined by the expression I , where P1 and P2 are the sound pressures at the propagation distances X1cm and X2cm in a steel material. A frequency f(c/s) is set so that alpha is about 2.0 or more. From the values of alpha and (f), f/2 is obtained. The value of (nj) is determined by the expression III, and the diameter D of the crystal grain is obtained by the expression II.

Filed: 1988-06-08
Abstract: PURPOSE:To accurately detect a local temperature rise even in a broad supervising space by obtaining the propagating speed of a supersonic wave in each virtual small space from a measurement result as if obtaining the solution of each element of a matrix. CONSTITUTION:The propagating speed of the supersonic wave in all routes 1 is registered in a memory 11. Based on the propagating speed of each route 1 registered in the memory 11, an arithmetic processor 10 obtains the propagating speed of the supersonic wave in each virtual small space by an operation as if obtaining the solution of each element of the matrix. That is, the solution is obtained as if solving a series of simultaneous equations. The propagating speed in each virtual small small space is converted into a temperature signal by the arithmetic processor 10, and displayed by a density, a color, numeric values, etc., according to the temperature signal at the position corresponding to each virtual small space on a display device 12. Thus, the two-dimensional temperature distribution in the supervising space can be shown.

Title: Control method for coil shape in strip winder
Inventor: ANABUKI YOSHINORI
IPC: B21C47/02
Filed: 1987-06-03
Abstract: PURPOSE:To accurately control the shape of a coil with a fixed image sensor by moving a winder in a width direction of strip material so that it takes a moving quantity proportional with a quantity of deviation between a stored edge position and a position to be detected. CONSTITUTION:In a cylinder control device 6, an electric current value corresponding to the deviation between the position of a cylinder 12 for moving a tension reel detected by a cylinder position detecting device 10 and a cylinder position command value outputted from a proportioning device 22 is inputted into a 2nd servo valve 8. Accordingly, the quantity of oil sent from the servo valve 8 to the cylinder 12 is changed with the deviation to move a tension reel 18. Therefore, the tension reel 18 is moved by a quantity of deviation from an edge position. When a strip is wound, the coil shapes of the strip 16 having different widths can be brought under highly accurate control.

IPC: H01L29/744
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To improve the breakdown resistance of an element, to reduce a turn-off loss, and to improve a high breakdown voltage and a yield. SOLUTION: In a semiconductor device for controlling power, an outermost N-type drain layer 12 is formed at a part that is positioned directly below an outermost gate electrode 8a in a P-type base layer 5, and at the same time a central N-type drain layer 13 is formed at a part being located immediately below a central gate electrode 8b in the P-type base layer 5. As a result, when a forward biasing is given to each gate electrode 8 (and the outermost gate electrode 8a and the central gate electrode 8b), the amount of carriers to be injected from each N-type emitter layer (and an outermost N-type emitter layer 6a and a central N-type emitter layer 6b) can be slightly controlled and the delivery effect of carriers on turn-off gate biasing increases. Therefore, accumulation time near the outermost N-type drain layer 12 and the central N-type drain layer 13 is reduced.
