Title: Method and device for measuring wave height
Inventor: ATOKAWA OSAMU
IPC: G01C13/00
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To make accurate measurements by making it possible to easily specify a wave front for measurement and to make measurement possible even at night or in the dark. SOLUTION: Visible laser beams L, L are mutually crossingly emitted from a pair of laser oscillators 1, 1 toward a wave front W, and the laser oscillators 1, 1 are put into upward and downward movements to vertically scan the crossing point P1 more rapidly than changes in vertical position of the wave front W occur, so as to recognize the wave front W. Thereby changes with time in vertical position of the wave front W recognized and the time of each change are stored in the form of images by use of a video camera 2, and data on the sequence of points of coordinate values obtained by converting the vertical positions of the wave front W on a screen into actual space coordinates according to the image data stored are obtained, whereby the height and length of each wave are measured from the data on the sequence of points.

Title: Photosensitive body
Inventor: YOSHINO KUNIHISA
IPC: G03G5/12
Filed: 1986-05-16
Abstract: PURPOSE:To enhance adhesion between the photosensitive body and a color separating material by bonding a layer having the color separating function to the photosensitive layer by the medium of a thermoplastic butadiene-styrene rubber adhesive. CONSTITUTION:The layer having the color separating function is bonded to the photosensitive layer by the medium of a thermoplastic butadiene-styrene rubber SBR adhesive. This thermoplastic butadiene-styrene rubber SBR is a block copolymer composed of especially arranged polystyrene blocks and polybutadiene blocks, and butadiene and styrene are copolymerized by the solution polymerization process using an organometallic catalyst other than the process for preparing the usual SBR, and this thermoplastic SBR is a nonadhesive polymer, but it can be made adhesive by adding various tackifiers, such as coumarone-indene resin or alpha-pinene resin, and it comes to bond well to glass, polyolefin, reinforced plastics, iron, and nonferrous metals, and since it is high in electric resistance and insulating, it is preferable for bonding the photosensitive body to the color separation material.

Title: Processing of suction roll shell for papermaking
Inventor: HINENO MINORU
IPC: D21F3/10
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To provide a processing method for prolonging the service life of a metal suction roll shell by more surely suppressing propagation of a crack generated on the inside face of the suction roll shell for papermaking caused by pressure to the tissue of paper fibers containing water in the midway of a papermaking process where the suction roll dehydrates the tissue by aspirating the water content in the tissue through many aspiration holes thereof while rolling, under a prescribed pressure. SOLUTION: A metal texture near the tip of a crack P1 of a suction roll shell 20 for papermaking is plastically deformed by applying an excess pressure F2 exceeding a prescribed pressure to the suction roll shell 20 for papermaking. By this method, the tip region of the crack is strengthened by work hardening according to the plastic deformation, thereafter a plastic deformation is not generated under a prescribed pressure F1 in a usual using condition because of an action of the work hardening, in stead, an elastic deformation is generated, then propagation speed of the crack is lowered.

Title: Different system linking device
Inventor: WATANABE MAKOTO
IPC: H02J3/04
Filed: 1990-04-28
Abstract: PURPOSE:To promptly release different system linking by turning off a semiconductor switch by an AND condition between an opening command signal and a current detection signal of a loop switch. CONSTITUTION:When an opening command is given to a loop switch 11 with an on-command given to a thyristor switch 19, the loop switch 11 is opened, and the current flowing therethrough is bypassed through the thyristor switch 19. Under this condition, when a closing command is given to section switches 5 to 10, they are closed to allow a current to flow because a different system is linked in this point of time, and when the current reaches a current detection level, a current detection signal is output from a current detecting circuit 21. As a result, the output of an AND circuit 22 becomes '1', which is the OFF command to cause a trigger circuit 23 to turn off the thyristor switch 11.

Title: Rectification device
Inventor: CHIKIRA HIROSHI
IPC: H02J7/34
Filed: 1987-05-11
Abstract: PURPOSE:To keep a battery always under complete charged condition, by monitoring the specific gravity of electrolytic solution of a battery at all times and by automatically switching the operation of a rectifier from floating operation over to uniform operation when the specific gravity of electrolytic solution gets reduced. CONSTITUTION:A specific gravity detector DET actuates a relay T when the specific gravity of electrolytic solution becomes reduced lower than a certain preset value. If the relay T actuates, a rectifier FC in floating operation will be switched over to uniform charging operation. The rectifier FC is switched from floating operation to uniform operation under the control of a control device CONT, with which DC power is applied to a load L uniformly charging a battery BAT. After that, the specific gravity detector DET reads the recovery of the specific gravity of battery electrolytic solution with a electrolytic solution specific gravity sensor HS to release the relay T which has so far actuated. The control device CONT thereby gets back the operation of the rectifier FC from uniform operation to floating operation, i.e. to normal operation.

Title: Semiconductor device
Inventor: HAYANO TETSUKAZU
IPC: H01L27/08
Filed: 1985-05-25
Abstract: PURPOSE:To produce an overvoltage-protecting element by a method wherein the arrangement of an N<+> buried layer in a P<-> substrate before epitaxial growing process is adjusted while collector current Ic is cut off when the voltage VCE between collector and emitter of PNP element in an N<-> epitaxial layer exceeds specified value. CONSTITUTION:An N<-> epitaxial growing layer 2 on a P<-> substrate 1 with an N<+> layer 3 buried therein is separated by a P<+> separating layer 4 to form an NPN transistor and a PNP transistor simultaneously on the N<-> island 2. When VCE of PNP element is increased, depletion layers are expanded upward and downward to make IC=0 before VCE reaches breakdown voltage BVCEO. The VCE at this time is decided by specific resistance, thickness, diffusion depth of collector of PNP element and layout of buried layer 3. Through these procedures, the PNP element can be used as an overvoltage-protecting switch by adjusting layout of buried layer only with the other parameters fixed making VC exceed specified value and IC=0.

A control circuit 5 transmits data of the frequency station which is newly received to a PLL circuit 4 and a tuner 2 receives the frequency station, corresponding to tuning voltage which a tuning voltage generation circuit 3 outputs and validates or invalidates SD according to the intensity of the electric field. The control circuit 5 checks SD of a reception signal inputted to the tuner 2 by an SD counting part 10. When SD is invalid even once, the system shifts to a next frequency station, thereby the data of the next frequency station in the PLL circuit 4 is set.
