Title: Piezoelectric electroacoustic transducer
Inventor: FUKAMI TATSUO
IPC: H04R17/00
Filed: 1982-11-29
Abstract: PURPOSE:To obtain a composite timbre output of sounds providing a proper accoustic sense, by varying the shape of a metallic plate interposed between a piezoelectric element and a diaphragm, and thus providing a piezoelectric oscillator with multiple peak frequency characteristics. CONSTITUTION:The piezoelectric oscillator 14 consists of the diaphragm 11, metallic plate 12, and piezoelectric element 13. The metallic plate 12 has outer diameter size between those of the diaphragm 11 and piezoelectric element 13 and its circumferential parts are cut to obtain a shape other than a circle. The piezoelectric element 13 is manufactured by polarizing porcelain such as zircon and lead titanate in its thickness direction. Since the metallic plate 12 depends upon the appearance when the circumferential part of the diaphragm 11 is viewed from the center point 15 of the piezoelectric element 13 and the relation between the Young's modulus E and density rho, the metallic plate 12 varies in value (E/rho)<1/2> when changing in shape to obtain variation in resonance frequency fr. The frequency characteristics of the piezoelectric oscillator 14 is double-peak response having two resonance frequencies fr1 and fr2.

Title: Lowering type refuge bed
Inventor: YAMAMOTO MASASUKE
IPC: E04H9/08
Filed: 1995-07-27
Abstract: PROBLEM TO BE SOLVED: To reduce injuries and death by pressure by supporting a base on a floor surface by a column and a beam and lowering the base to the inside of a frame by a base lowering mechanism. SOLUTION: When an earthquake sensing mechanism 4a senses a quake set beforehand, a lock mechanism 3b is moved to the outer part of an earthquake-proof frame, the lick of the lowering of a bed 1 is release and the bed 1 is lowered from the state of being supported on the floor surface to the inside of the frame of a refuge room 2. As a result, the bed 1 is promptly, surely and stably lowered to the inside of the frame of the refuge room 2 and falls down on a first air bag device 7 by the guidance of a guide roller 6 pivoted along the column 2a. Thus, even when furniture arranged near the bed 1 falls down to the bed 1 by the occurrence of an earthquake, the bed 1 is lowered to the inside of the earthquake-proof frame inside the refuge room 2 and falling directly on the bed 1 is prevented by the column 2a and the beam 2b for constituting the earthquake-proof frame.  Then, the possibility of getting a person sleeping on bedding injured or crushed to death is reduced.

IPC: G03G15/04
Filed: 1987-08-25
Abstract: PURPOSE:To enable easy adjustment of the pitch of exposure lines in a main scanning direction, by making it possible to freely adjust the angle of a transparent plate to the main scanning direction of a photosensitive body. CONSTITUTION:When a transparent plate 4 is perpendicular to an optical path, incident light 7 passes through points E and H on the plate 4 to reach a condensing point O. When the plate 4 is inclined at an angle alpha to a main scanning direction of a photosensitive body 3, the incident light is refracted at a point K on the plate 4, reaches a point N, at which it is again refracted, and reaches a condensing point 0'. Namely, with the plate 4 inclined by the angle alpha, the condensing point is shifted by 00'. Thus, by varying the angle of the transparent plate 4 with a relatively rough accuracy, an exposure line can be finely adjusted in the main scanning direction on a several micrometer basis. Therefore, the pitch of the exposure lines in the main scanning direction can be easily adjusted.
