IPC: B23Q1/00
Filed: 1999-06-09
Abstract: PROBLEM TO BE SOLVED: To make a linear motor driving and feeding device of a machine tool compact and further prevent thrust required for machining from being reduced. SOLUTION: A moving base 15 supporting a tool G for machining a work piece W is guided and supported to a base 12 so that the moving base 15 may be reciprocated. By a linear motor 16 constituted of a primary motor element 16a and a secondary motor element 16b opposed to each other, the tool G is reciprocated between an advancing position where the tool G is abutted on the work piece W and machining this work piece W and a retreating position where the tool G is separated from the work piece W. Either one of both of the motor elements 16a and 16b is shorter than the other in length of the reciprocating direction.  The motor elements 16a and 16b are arranged so as to be completely opposed in the reciprocating direction at the advancing position to be a stroke range to be used for machining of all stroke ranges of the moving base 15 and so as to be partially opposed at the retreating position to be the stroke range which is not used for machining.

IPC: A61M16/00
Filed: 1984-08-01
Abstract: A high frequency ventilator (10) which generates a high frequency pressure wave in a supply (26) of ventilating gas for supporting ventilation in air breathing animals. The high frequency pressure wave causes the ventilating gas to be exchanged and to diffuse through the animal's lungs fast enough to support ventilation without spontaneous breathing on the part of the animal and without the aid of a separate ventilator. There are means provided for producing a high frequency, variable period, variable amplitude pressure wave in said gas, which is polar relative to the static airway pressure in said animal, to actively force gas into and draw gas out of said animal.

Title: Image producing method
Inventor: TODA KUNIO
IPC: G03G15/09
Filed: 1988-06-30
Abstract: PURPOSE:To produce a high-quality image and to miniaturize a device by bringing a destaticized electrostatic latent image carrier into contact with a magnetic brush retained on the developing sleeve of a first developing unit, of which the impressed bias voltage is switched so as to be higher than during developing. CONSTITUTION:A toner image is transferred on an image-transferred body 17 in a transfer area Y, while the surface of an electrostatic latent image carrier 2 of which the toner image is deprived is destaticized by an eraser lamp 8. When toner retaining electrostatic charge comes in a first developing area X1, the developing bias voltage VB1 of a first developing sleeve 41 is already switched so as to be higher than during the developing. Electrostatically charged toner is recovered to the developing sleeve 41 by means of static electricity based on a voltage difference between the developing bias voltage VB1 and the surface potential of the electrostatic latent image carrier 2, and the scrape- off action of the magnetic brush on the developing sleeve 41. As a result, the necessity of a cleaning device is eliminated when two units of developing units are provided on the device to obtain the high-quality image, and the device can be thereby made compact and multifunctional.
