Title: Photosensitive unsaturated polymer and photosensitive resin composition containing the same
Inventor: YOSHIOKA SHIGEHIKO
IPC: C08F2/46
Filed: 1980-06-26
Abstract: PURPOSE: To provide a photosensitive unsaturated polymer which has excellent guick-curing characteristics and adhesion of cured film to a substrate, by reacting the hydroxyl group of a liquid vinyl polymer with the terminal isocyanate group of an unsaturated urethane oligomer.  
     CONSTITUTION: In an unsaturated polymer composed of a reaction product between a liquid vinyl polymer (A) having hydroxyl groups and an MW of 2,000W10,000 and an unsaturated urethane oligomer (B) having isocyanate groups at its terminal, said unsaturated polymer is obtd. by using a reaction product between a polyol compd. having hydroxyl groups and a polyisocyanate as said oligomer B having isocyanate groups at its terminal. Since the MW of this unsaturated polymer is increased, the curing rate of the polymer is faster than that of the oligomer B. Further since excellent adhesiveness to a substrate, which the liquid polymer A possesses, is entirely retained, said unsaturated polymer has well-balanced properties between quick-curing characteristics and adhesiveness.

Title: Controller for electric power steering
Inventor: FUKUYAMA YUICHI
IPC: B62D6/00
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To allow an electric power steering controller to stably control an electric motor under the state of a steering returning operation. SOLUTION: When a steering torque value T detected by a steering torque sensor exceeds, e.g. a set value T0 which specifies a dead zone, a steering condition is recognized and current feedback control is performed according to the steering torque value T detected, vehicle velocity V, motor rotation speed ω, and the actual current value (i) detected. When the steering torque value T detected is not greater than the set value T0 and the motor rotation speed ωis not smaller than a set value ω0 , then a steering returning operation is recognized and a predetermined motor application voltage VM corresponding to the vehicle velocity V is calculated to subject a steering assisting motor to open-loop control according to the voltage VM calculated.

Title: Reciprocating mechanism of cutter with relief and synchronizing driving method therefor
Inventor: IIZUKA TSUNESUKE
IPC: B23D3/02
Filed: 1988-04-11
Abstract: PURPOSE:To make it possible to set the amount of relief at an optimum value by performing a reciprocating motion of a cutter spindle and a relief motion of a cutter head by means of linear motors, feeding back the momentum so that synchronism of the cutter spindle and the cutter head is maintained and controlled, and bringing the speed of reciprocating motion of the cutter near the momentum and increasing the speed of the cutter head in return route. CONSTITUTION:When drive-control devices of each mechanism are previously inputted to NC control device based on a portion to be worked of a work 12 and operated, a spindle and the work are automatically rotated, and the spindle is periodically reciprocated by the operations of both linear motors 17, 21. A cutter head then makes a relief motion, and is driven-controlled so that one cycle of reciprocating motion of a cutter is exactly in synchronism with one cycle of relief motion of the cutter, head. In one cycle, the difference in delayed speeds of both linear motors can be freely and simply set, so that a return motion of the cutter head can be accelerated and the length of stroke can be freely set every work. A locus of the cutter 11 can thus inclined by changing input values, and even a tapered surface of the work with a taper tooth T can be simply machined.

Abstract: PURPOSE:To improve the stability and reliability without increasing the absolute number of tracks on the code plate by dividing units into two in the length direction of the tracks, and providing the same physical properties with an original code to one section and the opposite physical properties from the original code to the other. CONSTITUTION:The respective minimum read unit of length lambda of the code plate A are divided into two in the track length direction; and the original numerals are assigned to the section T2 and the reciprocal numbers are assigned to the other section T1. Plural sets of sensors S1 and S2 are arranged at a detection part B nearly at intervals 1/2lambda and differential amplifiers M are provided respectively. Each amplifier M subtracts the output of S2 from the output of S1 and outputs '0' when the result is negative or 1 when positive. Consequently, even if foreign matter sticks, the stability and reliability can be secured with one track as well as the use of two tracks.

Filed: 1983-05-18
Abstract: PURPOSE:To reduce the load to the program capacity by inverting and transmitting a specific bit every transmission through a central command microcomputer and resetting an abnormality detection timer with said specific bit through a terminal microcomputer. CONSTITUTION:A master microcomputer (muCP) 1 performs transmission, and a slave muCP 2 replies to the muCP 1. A master device 1 judges the input/output through a MAIN 4 and inverts 5 a specific bit of the transmission information for each transmission to a slave device 2. Then the operation is reset to the MAIN 4 after transmission 6, reception waiting 7 and reception 8. The device 2 resets an abnormality detection timer 3 with the inverted specific bit sent from the device 1. The timer 3 starts timing at and after a time point when the output change of the device 2 is stopped, and the device 2 is reset 14 when said timing action is through. Thus a program to detect the abnormality of transmission and a runaway are not needed for the device 2.
