Title: Toner bottle
Inventor: KOIDE TSUNETARO
IPC: B65D83/06
Filed: 1998-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a toner bottle constituted so that the need of an inner cap and the attachment and detachment mechanism thereof is eliminated and the used toner bottle can be distinguished from new one. SOLUTION: An aperture part 12 whose diameter is smaller than a cylindrical bottle main body 11 is formed at one end part of the main body 11. Then, a cap 13 is force-fitted in the inside of the aperture end of the aperture part 12 so that the flange part of the inside circumference thereof is set outside the aperture end surface. Besides, a thin part 13b from which the cap 13 can be broken is formed at the cap 13. The thin thickness part 13b is formed to be U-shaped and the inside of the U-shaped thin thickness part 13b is a bending part 13c. Thus, when the toner bottle is set at the prescribed position of a developing device, the cap is broken. Besides, when the toner bottle is reset, the bending part of the cap is returned to an original position.  Thus, since the complicated attachment and detachment mechanism and the space thereof are not required like the conventional inner cap, the constitution of the toner bottle is simplified and the cost thereof is reduced.

Title: Surface acoustic wave device
Inventor: FUJITA YUJI
IPC: C07C45/51
Filed: 1987-11-16
Abstract: PURPOSE:To obtain a sufficient side lobe suppression degree even in case of a surface acoustic device having an asymmetrical amplitude frequency characteristic by setting a geometrical phase difference so that an excitation source distribution of a surface acoustic wave which is excited by a unidirectional electrode has an orthogonal component, and this orthogonal component goes to roughly an opposite phase in an input electrode and an output electrode. CONSTITUTION:When a geometrical phase difference, an electrical phase difference, an hourly position of an excitation source, and the amplitude of a surface acoustic wave are denoted as phiM, phiE, (t) and A, respectively, a surface acoustic wave amplitude frequency characteristic H (omega) in a specific point by a unidirectional electrode is supplied by an expression I. The first term of the expression I and the second term show a response of a sending-out electrode and that of a reflecting electrode, respectively. In such a case, in case of phiM-phiE=((2n-1)/2)pi, the surface acoustic waves which are excited by the sending-out electrode and the reflecting electrode are in an orthogonal relation, and even in case of a normal type electrode constitution, the frequency characteristic goes to asymmetrical. Also, in case of ((2n-1)/2)pinot equal to phiM-phiEnot equal to 2nPI, when the sending-out electrode is used as a reference, the frequency characteristic goes to asymmetrical in the same way as the foregoing. In such a way, since the input electrode and the output electrode have reverse asymmetricalness, the side lobe suppression degree is improved.
