Title: In-car receiver for satellite signal
Inventor: AOSHIMA SHIGEKI
IPC: H01Q1/32
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To maintain always good receiving state by inspecting reception level and the output signal of oscillation gyro with a controller and conducting gyro controlling and step track controlling. SOLUTION: In tracking operation, reception level and the output signal of an oscillation gyro 26 are converted to digital signals by way of an A/D board 24 and supplied to a controller 28. The device 28 properly conducts the gyro control and step track control based on these signals. With the gyro control, an antenna beam is faced to a satellite direction by rotating the antenna 10 at an angular velocity (-ωG) of the same degree as the rotation angle (ωG) of a vehicle detected with the gyro sensor and opposite sign. With the step track control, the upper limit of the reception level is checked by slightly swiveling the antenna beam keeping the azimuth direction, and azimuth of the antenna beam is faced to the satellite direction by rotating the antenna 10 to the direction that the reception level increases.

Title: Dot printer head
Inventor: NORIKOSHI TAKASHI
IPC: B41J2/275
Filed: 1984-06-29
Abstract: PURPOSE:To make it possible to perform high speed printing, by rapidly stabilizing an armature by preventing the levitation of an armature stopper at the time of return by the armature stopper opposed to a core. CONSTITUTION:Printing is performed by exciting a coil 12 and attracting the rear part of an armature 18 to a core 13. When the supply of a current to the coil 12 is cut off, the armature 18 is returned by the force of a spring 24 and becomes stationary upon the contact with an armature stopper 25. Therefore, the armature 18 is not levitated from the yoke 11 or the core 13 by the counteraction of return operation and becomes stable rapidly. By this method, the same coil 12 can be continuously excited and high speed printing can be performed.

Abstract: PROBLEM TO BE SOLVED: To easily produce a duplicated mask for mass production at low cost by pouring a light-transmitting material into a mother die and transferring a proximity field exposure pattern fixed to the mother die to form a mask. SOLUTION: A mother die 11, having a proximity field exposure pattern which has a size smaller than the wavelength of light is prepared. A duplicated mask material 13 which is a light-transmitting material such as glass, resin (PMMA) and plastics is molten by heating and poured as molten into the mother die.
