Title: Linear pulse motor
Inventor: MIZUNO TSUTOMU
IPC: H02K41/03
Filed: 1985-11-29
Abstract: PURPOSE:To obtain a large thrust force by passing a magnetic flux through a secondary side traveling path along the longitudinal direction of a tooth, and sufficiently deepening the groove of a tooth to reduce a leakage magnetic flux. CONSTITUTION:Four magnetic field legs P1-P4 are arranged longitudinally of a tooth of a secondary traveling path 3 on a movable unit 1. Two teeth are formed on each field leg, and the teeth are displaced in phase by 1/4 pitch. Permanent magnets PM1, PM2 are formed on the backs of the legs P1-P4, and both are coupled by a yoke 5. Exciting windings C1-C4 are provided at the respective legs. With this construction, since the magnetic flux in the path 3 flows longitudinally of the teeth, a leakage magnetic flux can be reduced by deepening the grooves of the teeth, thereby obtaining a large thrust force.

Abstract: PURPOSE:To enable posture control of a probe in a flaw-detecting scanning to be simplified by providing a supersonic probe which is slid along a guide rail on a circular arc so that its center line always passes the center of curvature of the circular arc. CONSTITUTION:A slider 4 which is mounted on a supersonic probe 1 moves from an edge of a guide rail 3 on a circular arc to the other edge on a concentric circle so that a center of the probe 1 constantly passes the center of curvature of circular arc 0.

Title: Coal pulverizer
Inventor: MIGAKI HITOSHI
IPC: B02C15/04
Filed: 1990-10-09
Abstract: PURPOSE:To allow a coal pulverizer to correspond to both many kinds of coal and the rate of change in high load by comparing the detection value of mill differential pressure detected by a detection means of mill differential pressure with the preset value of mill differential pressure and slowing rotation of a rotary type classifier when the set value of mill differential pressure is larger than the detection value of mill differential pressure and speeding rotation of the rotary type classifier when the set value of mill differential pressure is smaller than the detection value thereof. CONSTITUTION:The deviation of mill differential pressure based on the signal of actual amount of coal obtained form a coal weighing machine 19 is checked for the relative characteristics of both previously programmed coal feeding amount and mill differential pressure in an r.p.m. controlling device 104 as a circuit for correcting r.p.m. by a signal sent from a mill differential pressure gage 17. When the signal of the measured mill differential pressure is larger than the set signal of mill differential pressure for the set feeding amount of coal, rotation of a rotary classifier is controlled by command sent from the r.p.m. controlling device 104 so as to reduce the r.p.m. of a variable speed motor 21 for the rotary classifier in order to make the mill differential pressure small. Reversely when the signal of the measured mill differential pressure is smaller than the set signal of mill differential pressure, the r.p.m. of the variable speed motor 21 is increased and rotation of the rotary classifier is controlled so that mill differential pressure is made high.

Title: Complementary insulated gate field effect transistor integrated circuit
Inventor: SHIZUKUISHI MAKOTO
IPC: H01L27/092
Filed: 1985-12-02
Abstract: PURPOSE:To reduce a variation in a threshold value voltage due to thickness of a gate insulating film by differentiating implanted ion peak density positions in n-channel type and p-channel type transistors. CONSTITUTION:After a p-type well 252, a field oxide film 260 and gate oxide films 264, 266 are grown on an Si substrate 250, B<+> ions, for example, are implanted. At this time, B<+> ions are implanted with an energy that B<+> ion flying stroke RP becomes equal as the thickness of the film 264 in an n-channel type transistor Q2, and B<+> ions are implanted so that ion flying path RP'' becomes sufficiently larger than the thickness of the film 266 in a p-channel type transistor Q1. As a result, the thickness of the film 264 is cancelled by the influence due to the variation in the ion implanting amount so that the threshold voltage of a gate electrode 274a becomes substantially constant in the transistor Q2. Since the influence due to a variation in the thickness of the film 266 is less in the transistor Q1, a gate threshold voltage becomes substantially constant.

Title: Motive power generating device
Inventor: ASADA KAZUHIKO
IPC: H02P6/14
Filed: 1995-10-18
Abstract: PROBLEM TO BE SOLVED: To limit the electric current flowing in an inverter by controlling the turning on/off timing of a switching elements so that electric currents can flow to the windings of the inverter in the direction in which magnetic fluxes generated from permanent magnets can be intensified in accordance with the phase of a DC power source. SOLUTION: A logic circuit 153 is connected to the output of a Hall IC 66, etc., which is a position detecting means, detects the angle of rotation of a second object 52 in accordance with the output, and outputs the detected angle of rotation to a driving circuit 154. The circuit 154 supplies electric currents to windings 60a-62b connected to an inverter 55 and causes the object 52 to generate a torque by causing permanent magnets 63 and 64 to generate peripheral forces counterclockwise. The driving circuit 154 adjusts the turning on/off timing of each switching element so that the timing can become slower than the actual position received from the logic circuit 153. Therefore, the value of the electric current flowing in the inverter can be limited and, at the same time, the generated torque can be secured by the effect obtained when the magnets 63 and 64 are equivalently intensified.
