IPC: G01K7/01
Filed: 1989-11-20
Abstract: PURPOSE:To obtain a highly reliable measuring instrument with simple constitution by providing plural diodes and a means which measures their forward rising voltage. CONSTITUTION:The diodes Si(1,1), Si(1,2) - Si(3,3) are arranged in a grating shape and, for example, a diode Si(1,1) is connected to an X1 line and a Y1 line. A computer 3 drives an X- and Y-line coupling driver 4 to connect one desired line among X1-X3 and one desired line among Y1-Y3 to a constant- current source 5, and supplies a constant current to the diode at their intersec tion. Then X-axial and Y-axial connection scanners 1 and 2 are used to connect the X1 line to an X line and the Y1 line to a Y line. At this time, the variable resistance of the constant current source 5 is adjusted to supply a constant current Ic from the X1 to the Y1 and then the diode Si(1,1) becomes forward, so a current flows and a voltage Vd is generated across the diode. The Vd is found from the voltage of the voltage across the variable resistance, A/D converted 6, and inputted to the computer 3, and the value is compared with a stored forward rising voltage Vd-temperature characteristic to find the temper ature.

Title: Method and apparatus for producing thin film
Inventor: CHIN KAYU
IPC: C08L23/20
Filed: 1999-10-25
Abstract: PROBLEM TO BE SOLVED: To provide a method and apparatus for easily mass-producing a thin film. SOLUTION: Water being a non-solvent flows in from an inlet 11 and impinges against first and second cushioning plates 121, 122 to be reduced in velocity to generate no turblent flow. The water passes the cushioning plate set 12 to enter a molding tank 3 and flows along a flow guide plate set 31 to generate no turblent flow. At this time, a polymer solution is infected in the stable water flow in the molding tank 3 by a metering pump 22 and guided by the flow guide plate set 31 to diffuse. Since the polymer solution is not dissolved in water and the surface tension thereof is relatively large, the polymer solution is diffused on the surface of water to form a polymer thin film. A nonwoven fabric 320 is laid under the thin film and the thin film is taken up along with the nonwoven fabric 320. Since moisture and a solvent are bonded to the taken-up nonwoven fabric 320 and thin film, a drying device 35 is arranged to remove the moisture and solvent contained in the nonwoven fabric 320 and the thin film to facilitate the preservation of the thin film.

Title: Method of giving disk error correcting code
Inventor: MIGEERU MARIO BURAAMU
IPC: G11B20/12
Filed: 1990-11-09
Abstract: PURPOSE: To entirely increase a storage capacity by continuously decreasing the number of redundant byte of a code, decreasing the number of a correctable error and continuously decreasing the number of the correctable error in accordance with the decrease of the necessity of an error correcting capability. CONSTITUTION: A data byte and redundant byte are stored with a clock frequency proportional to the inner diameter in each band. The number of the redundant byte within the code is continuously decreased every continuous each band in accordance with approaching to the innermost side. Therefore, the number of correctable error is continuously decreased in corresponding to the fact that the nearer the center side of the disk, the less the error ratio. A new decoder 25 which is less complicate than a RS decoder, whose error correcting capability is higher than it in the outer band and which can largely save the redundancy in the inner band, is adopted in this method. By this way, the storage capacity is entirely increased.

Title: Packet data transfer system
Inventor: TAKANO RYOJI
IPC: H04L47/43
Filed: 1991-11-19
Abstract: PURPOSE:To improve the processing capability of an exchange economically by allowing an exchange to decide a transfer destination-exchanged device with control information inserted in a prescribed position of packet data from the exchanged device and to transfer the packet data to the destination. CONSTITUTION:A packet line controller 14 divides packet data transferred from an ISDN exchange 2 or a packet exchange network 3 into division data in a unified timing in a packet exchange subsystem 1 and adds control information to form a frame. Moreover, a packet call processor 15 generates a similar frame and transfers it sequentially to an exchange 16. The exchange 16 branches control information from the frame transferred from the processor 15 or the controller 14 to identify the controller 14 and the processor 15 thereby transferring the division data from a transfer source to a transfer destination. Thus, the exchange processing is simplified to improve the exchange processing capability of a packet exchange economically.
