Inventor: FUKATSU HIROICHI
IPC: F04B43/12
Filed: 1991-10-28
Abstract: PURPOSE:To simplify the pump structure and to realize a compact size and a light weight by making an elastic plate resonate by the oscillation of a bimorph oscillator so as to increase the force-feeding force of a liquid. CONSTITUTION:At the tip of a bimorph oscillator 7 made by connecting piezoelectric members 11 and 13 on both sides of an intermediate diaphragm 9, an elastic plate 15 is installed. One end of the elastic plate 15 is connected to a suction port along the base end to the front end of the plate 15, and flexible tubes 19 and 23 connected to a discharge port are installed to the other end of the plate 15. By applying an AC voltage of the frequency almost coincident with the intrinsic frequency of the elastic plate 15 to the piezoelectric members 11 and 13 to oscillate the bimorph oscillator 7, the elastic plate 15 resonates, and the oscillation energy of the elastic plate 15 is transmitted to a liquid in the tubes 19 and 23 positioned at the front end of the elastic plate 15, so as to feed the liquid forcibly.

Title: Cleaning device
Inventor: HIKINO AKIRA
IPC: G03G21/10
Filed: 1987-12-08
Abstract: PURPOSE:To prevent a flaw harmful to a photosensitive body from being generated by providing a sheet member whose surface is formed smoothly and friction coefficient is low at the photosensitive body side of a toner receiving magnet in a cleaning device. CONSTITUTION:On the plane confronting with, especially the photosensitive body 1 of the toner receiving magnet 6, the sheet member 10 such as a film sheet having extremely smooth plane is arranged. Therefore, a toner 9 or paper powder 8, etc., remaining on the photosensitive body 1 after the transfer of a toner image are scraped out by a blade being abutted with the photosensitive body 1, and a part of scraped toner is attached on the toner receiving magnet 6 via the sheet 10. Also, the paper powder 8 is mixed in the toner 9 and similarly, it is attached on the toner receiving magnet 6 via the sheet 10. However, since the surface of the sheet 10 is formed extremely smoothly and also it is made of a member whose friction coefficient is low, the gravity of the toner or the paper powder overcomes the magnetic force of the toner receiving magnet 6, then, it drops. Thereby, the accumulation of the toner or the paper powder which generates the flaw harmful to the photosensitive body 1 can be prevented from occurring.

Abstract: PROBLEM TO BE SOLVED: To obtain a smooth image by correcting isolated points in the vicinity of edges of an image so as to correct deformation of edges of characters and line drawings. SOLUTION: Picture elements of a received image are detected based on the position and the number of black level picture elements (when a background is white) in a filter (window) set to the received image (S1, S2), and when a picture element is detected, the picture element is used for a start point of a vector, and another picture element is detected based on the position and the number of the other picture elements and to be used for an end point of the vector. Thus, the detection of the direction of edges of a character or line drawing image is detected (S3, S4, S5). An image with smoothed edges is generated by moving isolated point picture elements and deformed picture elements.

Title: Mobile station device for satellite communication
Inventor: MASUYAMA YUJI
IPC: H01Q3/04
Filed: 1996-11-22
Abstract: PROBLEM TO BE SOLVED: To precisely and easily perform an initial acquisition of a satellite without lowing an antenna driving speed for initial acquisition by estimating a receiving level peak from stored receiving levels at approximately the maximum receiving level by the least squares method. SOLUTION: When starting the initial acquisition, a controller generates an antenna driving pattern for the initial acquisition, and makes an antenna perform a steady uniform driving revolution while performing an oscillation/ revolution correcting processing. Then, it determines whether or not a signal is received, and stores the azimuth angle and the receiving level of the antenna. If the spatial revolution of the antenna is detected, the driving is stopped and a receiving pattern is estimated by the least squares method using the receiving level data at several points before and after as centering the receiving level at the maximum point from among the stored receiving levels, and its peak value and azimuth angle are computed. Then, the antenna is driven to thus computed azimuth angle and the initial acquisition is completed.
