Filed: 1990-05-22
Abstract: PURPOSE:To obtain a small-sized device in which the occurrence of fogging and faulty transfer are prevented by directly transferring photoconductive toner left on a conductive drum to a paper to be transferred. CONSTITUTION:The conductive drum 22 is uniformly coated with the photoconductive toner 21, and the toner is electrostatically charged to be negative by an electrostatic charger 24. Thereafter, the toner is irradiated with light 25 synchronizing with the signal of an image or a character, etc., so that an electrostatic latent image is formed on the toner 21. At such a time, the surface potential of the toner 26 which is not irradiated with the light is not changed but the toner 27 which is irradiated with the light is polarized and the surface charge thereof is eliminated. Then, a separation means 28 makes an electrostatic charger 29 generate the ion of reverse charge to the charge of the toner 26, so that the toner is scattered from the drum 22 and sucked by a suction pump 30. Meanwhile, the toner 27 left on the drum is transferred to the transfer paper 33 and fixed by a fixing roller 35.

Abstract: PURPOSE:To restrain a gray zone from being generated by a side erasing operation and to ensure a sufficient S/N by a method wherein the front part at the contronted face of ferromagnetic metal thin films is installed on the overwriting side where an overwriting operation is performed. CONSTITUTION:When confronted positions of ferromagnetic metal thin films 60, 63 and 75, 78 on magnetic heads 57, 58 are displaced to the direction of a track width, a leakage flux is generated from edges of the ferromagnetic metal thin film 60, 63 and 75, 78 which have been displaced to the overwriting side where an overwriting operation is performed. However, since said ferromagnetic metal thin films 60, 63 and 75, 78 are installed in the same direction as the direction of the track width, angles theta1, theta2. formed by the ferromagnetic metal thin films 60, 63 and 75, 78 displaced to the overwriting side and by magnetic core parts 59, 62 and 74, 77 faced with them do not form acute angles even when they are displaced to either side of the direction of the track width. Consequently, a leakage magnetic field from the edges of the ferromagnetic metal thin films 60, 63 and 75, 78 is weak, the generation of a gray zone which is side-erased is suppressed, and a sufficient S/N is obtained.

Title: Vibration supressing method of marine two-cycle three-cylinder internal combustion engine
Inventor: MATSUI TAKEO
IPC: F16F15/22
Filed: 1982-07-28
Abstract: PURPOSE:To reduce vibration by providing a heavier weight at the reciprocating part of an engine and setting the inertia efficiency of a flywheel high. CONSTITUTION:A flywheel F is disposed at the end part of an engine, the first, the second and the third cylinder K1, K2 and K3 are arranged in order after the flywheel, and a propeller P is disposed at the side opposite to the flywheel, forming a vibration mode curve M which passes through them. A greater ratio of amplitudes of (d) at the end of the engine and at the end of the propeller (e) may provide a smaller amplitude which is produced at the end of the engine. The torsional amplitude of (d) is in proportion to approximately a square of (d)/ (e). Under the condition of the same total vibromotive force, a greater difference between a total inertia efficiency at the engine side and that at the propeller side lower than it may provide smaller torsion amplitude. In two-cycle three- cylinder engine, its inertia efficiency may be increased by increasing the weight of the cylinder part, however, the three-cylinder engin has an extremely short full length. In the engine, even if having a minimal inertia efficiency, an amplitude ratio of (d)/(e) may be greater than 1 by mounting a flywheel which has an inertia efficiency over that of one piston part of the engine.
