IPC: G02F1/01
Filed: 1985-09-26
Abstract: PURPOSE:To obtain a large polarizing angle by reflecting light between a magnetized magnetic body and a film having a high reflection factor plural times. CONSTITUTION:Current I is made to flow into a coil 5 and a magnetic field is generated in the magnetic body 2 in the arrow direction e.g. Linearly polarized light 4a is irradiated from a part on which a metallic film 3 is not arranged to a glass body 1 at an angle approximately vertical to the surface of the magnetic body 2.

Title: Linear ball bushing
Inventor: KONDO HIROMITSU
IPC: F16C31/04
Filed: 1994-09-07
Abstract: PURPOSE:To eliminate additional fastening for preventing balls from dropping by constituting a linear ball bushing in such a way that balls are held due to the deviation of the pocket of a cage from the holding hole of the holding cylinder fitted around the outer periphery of the cage. CONSTITUTION:A linear ball bushing comprises a cylindrical cage 1 in which a lot of pockets 1a are formed, balls 2 contained in the pockets 1a and the holding cylinder 3 fitted around the outer periphery of the cage 1. The holding cylinder 3 has holding holes 3a corresponding to the pockets la of the cage 1. The holding holes 3a have the same diameter as that of the pockets 1a, but the center of each holding hole 3a is deviated from the center of each pocket a distance S in the axial direction, and a part of the peripheral edge covers a part of the pocket 1a from the outer diameter side. For this reason, the movement of the ball 2 contained in the pocket 1a toward the outer diameter side is restricted by a part of the peripheral edge covering the pocket 1a of the holding hole 3a. Therefore, the movement of the ball 2 toward the inner and outer diameter sides is restricted by the inner diameter side of the pocket 1a and a part of the peripheral edge of the holding hole 3a, which prevents the ball 2 from dropping out from the cage 1.

Title: Circuit and method for driving piezoelectric transformer
Inventor: FURUHASHI NAOKI
IPC: H01L41/107
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To realize maximum dimming range and to prevent the heat generation from the parts of a drive circuit by driving a piezoelectric transformer with time division frequency signals outputted from a selecting means. SOLUTION: A dimming circuit 22 is dimmed at the dimming frequency of a triangular wave oscillating circuit 35 when an alternating current I0 continuously flows at a desired value, or at the dimming frequency of another triangular wave oscillating circuit 34 when a driving frequency is swept due to insufficient output. In addition, the circuit 22 is dimmed with the dimming frequency of the circuit 34, by setting the time constant of an integration circuit 26 before a cold cathode-ray tube is turned on after the power supply is made to the inverter of a piezoelectric transformer, or with two different frequencies of triangular wave oscillating circuits 34 and 42, and a drive-off signal is outputted based on the AND of the outputs of comparators 37 and 36 when the inverter of the transformer is operated in a no-load state.  Therefore, the maximum dimming range can be realized by driving the piezoelectric transformed, and at the same time, the heat generation from parts can be suppressed, because the effective value of the current flowing to the drive circuit of the transformer drops.
