Title: Control method for head for propulsion
Inventor: MUKONO KATSUHIKO
IPC: E21B7/04
Filed: 1995-02-23
Abstract: PURPOSE: To follow up a head for propulsion accurately to a propulsion design line by offsetting the place of reference and the direction of reference to the inside in the radial direction of the propulsion design line and applying a fuzzy inference when the propulsion design line curves. CONSTITUTION: The place P of head 4 itself for propulsion to a propulsion design line K is detected, and a distance Dh from the place of reference Q on the propulsion design line K and angular difference θh to the direction of reference Tk of the propulsion design line K are input. The direction of control and a controlled variable to a pressure-receiving surface are output by using a fuzzy inference having a fuzzy rule. In the control method of the head 4 for propulsion, the place of reference Q is offset to Q' separated by Do to the inside in the radial direction of the design line K when the propulsion design line K curves. The direction of reference Tk is offset to Tk" so as to reach angular difference θo to the inside in the radial direction of the design line K. These quantities of offset Do, θo are input, and the head 4 for propulsion is controlled by applying the fuzzy inference.

Title: Dry lithographic printing ink
Inventor: MATSUMOTO MINORU
IPC: C09D11/02
Filed: 1990-02-16
Abstract: PURPOSE:To provide a low-cost dry lithographic printing ink excellent in shelf stability, scumming resistance, the gloss of printed matter, etc., by using a specified rosin-modified phenolic resin as its varnish component to form a W/O emulsion. CONSTITUTION:A rosin is thermally reacted with a phenol in the presence of an acid catalyst. The reaction product, if necessary together with an alkylphenol containing 4-12C alkyl, is reacted with formaldehyde in the presence of an acid catalyst to give a novolak. If necessary, a polyhydric alcohol in an amount of at most 10wt.% based on the novolak is used to esterify the novolak, thus giving a rosin-modified phenolic resin. This resin is used as varnish component, which is mixed with necessary pigment, solvent, emulsification accelerator, water, etc. A W/O emulsion is formed from this mixture by using, e.g. a high-speed mixer, thus producing a dry lithographic printing ink.

Abstract: PURPOSE:To measure a span length with high accuracy by mounting antennas in the positions where half the distance between the insulator supporting points of the wire tightening plates on both sides of steel tower arms as base points and analyzing the phase differences of the signals transmitted from artificial satellites. CONSTITUTION:The respective base points X and Y of the span S to be measured of the steel towers 1, 1' are provided on both sides of the steel tower arms and are determined in the positions of half the distance (l) between the insulator supporting points of the wire tightening plates 2a, 2b which support insulators. The signal receiving antennas 3, 3' are installed at these base points to receive time signal radio waves 11 from the artificial satellites. Many pieces of the artificial satellites already turn around the earth and the signals of the artificial satellites are receivable in most areas on the earth. The atomic timepieces are mounted in the artificial satellites and the exact time signal radio waves of about 1.2GHz and 1.5GHz frequency are transmitted. The time signal radio waves are received and the phase differences of the received radio waves are generated from the difference in the arrival time of the radio waves at the different two points. Such differences are inputted to, for example, a floppy disk. The phase differences are processed by personal computers 6, 6' and the span length S is determined.

Title: Transmission system for optical communication
Inventor: ITSUSHIKI NORIO
IPC: H04B10/272
Filed: 1983-03-07
Abstract: PURPOSE:To reduce the number of photodetecting elements down to just one and to attain a small-scale of the titled transmission system with a low cost, by using a stop-down optical transmission line at a center terminal. CONSTITUTION:A center terminal drives light emitting elements LED1-LEDn and calls out each local terminal. Each local terminal transmits the information on the sensors and switches belonging to the terminal itself in the prescribed order to light transmission lines L1-Ln from the light emitting element LED of the local terminal. Then the information is supplied to a photodetecting element PD from optical connectors C1-Cn of the center terminal device #0 via a stop- down optical fiber nF1. At the same time, the terminal #0 processes and edits the information given from local terminals #1-#n to produce the signal for control of a load device of each local terminal and transmits this signal again to the PD of each local terminal from elements LED1-LEDn of the center terminal via optical fibers FT1-FTn. This procedure is equal to the conventional system.

Abstract: PROBLEM TO BE SOLVED: To restrain generation of switching noise by outputting a drive signal, based on the capacity of a snubber capacitor connected is parallel and/or the output capacitor of IGBT and the inductance of the primary winding of a transformer. SOLUTION: In this converter 20, the total of a Zener voltage VZ of a Zener diode 21 connected across the primary winding of a transformer 11 and a boundary layer voltage VD of a clamp diode 22 are selected, so as to be roughly equal to or smaller than a terminal voltage V1 of a DC power source 1, and a snubber capacitor 23 is connected between the collector and emitter of an IGBT 12. A drive circuit 17 outputs a drive signal where the period for turning off the IGBT 12 is made into a value, based on the total time of a time T0 =π.(L.C)<1/2> from the inductance L of the primary winding of the transformer 11 and the capacity C of the snubber capacitor and the reset time TR of the transformer. It is thus possible to restrain a rate of change in a voltage VCE between the collector and emitter of the IGBT12 for reduction in switching noise.
