Title: Optical transmission module
Inventor: HENMI NAOYA
IPC: H04B10/2507
Filed: 1988-06-06
Abstract: PURPOSE:To prevent a transmission code error due to TM mode oscillation by specifying the angle between the TE polarization output surface of a semiconductor and the axis of the input-side polarizer of an optical isolator. CONSTITUTION:The optical isolator 3 is provided so as to prevent part of the output light of the semiconductor laser 1 from being reflected by the input or output terminal, etc., of an optical fiber 4 and coupled with the semiconductor laser 1 as return light. Then the axial direction of the polarizer at the input terminal is set at 45+ or -10 deg. to the axis of polarization of the TE mode of the laser so that the TE mode oscillation light outputted by the laser is not cut off by the polarizer at the input terminal of the optical isolator 3 at the time of direct modulation. In both the TE and TM modes, a half of the output is outputted without being cut off by the optical isolator 3. Consequently, the optical transmission module is obtained which generates no code error due to the TM mode oscillation even if the laser performs TM mode oscillation in the direction modulation.

Title: Piezoelectric actuator
Inventor: YAMAKAWA HIROSHI
IPC: F04B9/00
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To facilitate manufacturing of a piezoelectric actuator, by providing it with a pressurizing mechanism for pressing a lower member having a vibrator against an upper member at a constant pressure using a plate member and an elastic member. SOLUTION: After a piezoelectric vibrator 4 having a piezoelectric element 24 is installed in the actuator, an upper member 2 and a plate member 10 are screwed down each other. At this time, a wave washer 8 is used as an elastic component. Because a height of the wave washer 8 is slightly higher than a height A from a top of a bottom plate 60 in a plate member 10 to a bottom of a bottom plate in a lower member 6, the wave washer 8 is pressed and shortened to the height A and has force of restitution, the lower member 6 is pushed up, and the piezoelectric vibrator 4 is sandwiched with an upper member 2 and a lower member 6 at a constant pressure. The wave washer 8 and the plate member 10 act as a pressurizing mechanism. Therefore, a sandwiching pressure of the piezoelectric vibrator can be determined just by controlling the height A and a height of the wave washer 8.

Title: Method for displaying variable information
Inventor: BRAND PETER
IPC: G09G3/20
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To reliably display a partial small capacity of information satisfactorily readable even in a low ambient temperature area, and to avoid heating of a display unit, by making a switching time for a liquid crystal cell of the second display shorter than that of a crystal cell of the first display. SOLUTION: In an automobile display unit, a run speed is displayed in a partial display area 8 of a dot matrix 1 and a display area 27 of a display 3, and distance display 10 is additionally displayed on a display 1. The display unit is driven to cope with a transition temperature or limit temperature, for example from 0 deg.C to -10 deg.C. When an ambient temperature is lower than the limit temperature of -10 deg.C, only the display 3 having a short-switching time is driven since reliable display is impossible in the dot matrix display 1 because of a long switching time. Partial information relating to safety in a speed display 9 is still displayed to allow satisfactory reading for the display 3.
