Abstract: PURPOSE:To prevent return of the reflected light of a laser beam to a semiconductor laser light source by using a polarizing plate and 1/4 wavelength plate. CONSTITUTION:A laser beam outputted by a semiconductor laser 1 and having the plane of polarization parallel to a P-N junction face passes through a polarizing plate 6, and is polarized to circularly polarized light by a 1/4 wavelength plate 7 disposed so as to increase a 45 deg. angle to the P-N junction face. A drum 5 is optically scanned by this circularly polarized light via a scanning part 3 and an imaging lens 4.

Title: Piezoelectric transformer
Inventor: UEDA MASANORI
IPC: H02M3/24
Filed: 1993-07-12
Abstract: PURPOSE:To restrain a spurious emission and a transmission loss, to restrain unwanted vibrations or to restrain chippings by a method wherein the parallel distance (crossing width) of the crossed part of the teeth of a comb for one pair of electrodes is set at a specific multiple of the resonant wavelength of vibrations in the width direction of a piezoelectric-substance substrate. CONSTITUTION:The parallel distance L of the crossed part of one pair of electrodes 2a, 2b which are attached to the surface of a substrate 1 is set at six to ten times the resonant wavelength lambda of vibrations in the width direction of the substrate 1. That is to say, the smaller the parallel direction of the crossed part of the pair of electrodes is set, a spurious emission can be suppressed effectively, but a propagation loss is increased because vibration energy is hard to confine. In order to restrain the spurious emission without increasing the propagation loss, the crossing width is set at six to ten times the resonant wavelength. Thereby, it is possible to restrain the spurious emission and a transmission loss, to restrain unwanted vibrations or to restrain chippings.

IPC: H02G5/06
Filed: 1993-07-12
Abstract: PURPOSE:To reduce the size while enhancing the reliability by setting the ratio between the diameter of a high voltage conductor and the inner diameter of a metal enclosure larger than a specific value, setting the ratio between the diameter at a joint and the inner diameter of the metal enclosure within a specific range, and coating the bottom of the metal enclosure with a dielectric material in the vicinity of an insulating spacer. CONSTITUTION:A high voltage conductor 5 is made thin such that the ratio D/d1 between the diameter d1 thereof and the inner diameter D of a metal tank 1 is larger than 3.0. The inner diameter d2 at a joint 3 is determined such that the ratio D/d2 between the diameter d2 at the joint 3 and the inner diameter D of the metal tank 1 is in the range of 2.7-3.0. Furthermore, the bottom of the metal tank 1 is coated with a viscous substance 7 in the vicinity of an insulating spacer 4. This structure lowers the electric field on the inner face of the tank while preventing the concentration of the field on the high voltage conductor side without enlarging the metal enclosure thus lowering the electric field at the joint. Consequently, a metallic foreign matter is prevented from adhering to the insulating spacer or shifting to the high voltage conductor side.
