Abstract: PURPOSE:To enhance the degree of freedom of the selection of materials constituting a diaphragm by providing a terminal of the other electrode connected by a conductor through the inside of a piezoelectric substance to one electrode of a piezoelectric element. CONSTITUTION:In mounting a diaphragm 8 on one electrode 4B of the piezoelectric element 6 where electrodes 4A, 4B are placed on the front and rear sides of the plate shaped piezoelectric substance 2, a terminal part 20 connected to the other electrode 4B through the conductor 18 penetrated through the said piezoelectric substance 2 is provided onto the piezoelectric substance 2 of the one electrode 4A without the diaphragm 8 mounted thereupon. A lead wire 12B to the electrode 4B is connected electrically to the electrode 4A exposed with the piezoelectric element 6 not through the diaphragm 8. Thus, it is not required to form the diaphragm 8 by a conductor or a material with low resistivity.

Filed: 1984-08-31
Abstract: PURPOSE:To enable bending moment applied to a reach arm to be reduced even if excessive tension acts on a seat belt through an impact force, by constituting an end arm disposed on an end of the reach arm to be folded to the seat side. CONSTITUTION:A reach arm R is constituted from a base arm 16, an end arm 17 and an elastic plate 18 for holding these arms linearly.

Title: Optical scanning device
Inventor: ARIKI YOSHIO
IPC: G02B26/12
Filed: 1987-07-23
Abstract: PURPOSE:To increase an angle of deflection and to reduce the overall size of a device regardless of the simple constitution of an optical system by varying the distance between the optical system and the deflecting surface of a deflecting means in the direction of the optical axis and varying the slit width of a slit according to the distance. CONSTITUTION:A light beam which is collimated by a coupling lens 2 input a converged beam close to parallel luminous flux forms its image on the reflecting surface 6a of a rotary polygon mirror 6. The light beam which is polarized by the rotary polygon mirror 6 after passing through a spherical single lens 8 is reflected by a reflecting mirror 9 in a toric shape and projected on a photosensitive drum 10. The spherical single lens 8 almost compensates field curvature and distortion in a main scanning direction (x) mainly and the reflecting mirror 9 compensate the residue. Further, surface tilt correction is made by the curvature in the subscanning direction (y) of the reflecting mirror 9. Consequently, even if the angle of deflection is increased, the field curvature and distortion are all suppressed within permissible ranges in the main scanning direction and subscanning direction.

IPC: G02F1/1337
Filed: 1984-08-31
Abstract: PURPOSE:To suppress light leakage from picture elements and to obtain a clear color image having high contrast by forming insulating layers on the parts corresponding to the parts between plural display electrodes on the formation side of filters for the three primary colors so that the layers are higher than the surfaces of the filters. CONSTITUTION:The insulating layers 7R+G, 7B+R, 7G+B are formed between signal electrodes 3 so that these layers are higher than the surfaces of the filters for the three primary colors which are formed on the upper surfaces of the electrodes 3, so that rubbing parts can be correctly formed on the top parts in a required direction.
