Title: Image forming method
Inventor: NAKANISHI TATSUO
IPC: G03G15/02
Filed: 1989-02-01
Abstract: PURPOSE:To suppress the occurrence of a discharge activating source and to stably obtain a high grade image free of image flow and blur by electrifying the surface of a photosensitive body while the body is brought into contact with a conductive member. CONSTITUTION:The surface of the photosensitive body 1 is uniformly electrified by a conductive roller 2, and original-exposed by an exposing optical system 7, thereby forming an electrostatic latent image corresponding to the original on the photosensitive body 1. The image is developed by a developing device 8 to form a toner image. The obtained toner image is destaticized by a static destaticizing lamp 9 to attain an easy-to-transfer condition, and then transferred on a transfer material P by a transfer electrode 10. Since contact electrification is performed by employing a conductive member for the electrifying mechanism, the occurrence of a discharging source such as ozone is suppressed to stably obtain a large number of high grade pictures free of picture flow and blur.

Filed: 1990-01-31
Abstract: PURPOSE:To easily obtain an easily visible image for a diagnosis by suppressing a pixel value of an image of a fat part by correcting easily spatial sensitivity ununiformity at the time when a surface coil is used. CONSTITUTION:A surface coil 81 is placed roughly in parallel in the Y axis direction of an image, and since fat 82 contacts closely in parallel, a signal of the backbone 83 separated from the surface coil 81 is small, the part of the fat 82 shines in white, and it becomes difficult to read an image of the backbone 83. Therefore, by utilizing a fact that the surface coil 81 is parallel to the Y axis of a screen, a parallel pixel value P(x) is calculated, and with regard to the part limited by a threshold P0 processing of a curve P(x), an approximate primary function F(x) is derived. By allowing an inverse function of this F(x) to apply, the curve P(x) is corrected as P'(x). In such a way, the pixel value which is abnormally high in the part of the fat 82 is suppressed, and an easily visible image is obtained.

Title: Mirror surface active supporter
Inventor: NISHIMURA SHIRO
IPC: G02B23/02
Filed: 1988-02-02
Abstract: PURPOSE:To obtain high rigidity against rigid body displacement even if the diameter of a mirror increases by supporting a mirror at three points on a mirror cell and restraining the relative displacement between the mirror and mirror cell in six directions in total which are so combined as to absorb the displacement. CONSTITUTION:The mirror 1 is supported at the three points, where six degrees of freedom of the mirror in total are restrained. Further, the six degrees of freedom are so combined that there is not any influence of the relative deformation between the mirror 1 and mirror cell 2. Then when the mirror 1 changes its attitude, or when relative displacement like thermal deformation is caused between the mirror 1 and mirror cell 2, the mirror 1 causes rigid displacement or rigid rotation. Consequently, elastic deformation between mirror support points is suppressed below a permissible value and support point intervals are wide, so high rigidity is obtained against the rigid displacement, specially, rotation around an (x) axis and a (y) axis.

Title: Liquid flow detector
Inventor: ISHIZUKA AKIRA
IPC: G01F3/00
Filed: 1979-03-02
Abstract: PURPOSE: To simply detect the outflow of a liquid by a method wherein a liquid level detector for an overflowing liquid in a storage container and a liquid-discharging pipe which has an orifice function provided on the liquid outflow side of the storage container are utilized.  
     CONSTITUTION: A sample liquid is led to flow in through a guide pipe 6 and part of the liquid is discharged through an orifice, then the rest of the liquid flows in a storage container, but if the resistance of flow passage on the container side 8 is made smaller than that of the orifice 11, most part of the sample liquid flowed through the pipe 6 flows into the container 8. When a suitable amount of the liquid has flowed into the container, a floating type switch 9 operates and renders a signal from a signal line S. Since the sample liquid led to a fixed quantity tank 1 flows into it from a valve 3, the sample liquid does not flow into the container 8 if the valve 3 of the tank is operated to close by the signal from the signal line S. Therefore, the liquid in the container 8 is discharged through the orifice 11 and simultaneously the switch 9 is automatically reset. By this constitution, the existence or non-existence of the sample liquid can be detected, and the amount of overflowing liquid from the fixed quantity tank can be set without difficulty.

Title: Electron-beam exposure method
Inventor: SHINMOTO TAMON
IPC: H01L21/027
Filed: 1992-02-10
Abstract: PURPOSE:To form a uniform pattern by a method wherein the focus of an electron beam for an auxiliary exposure operation is displaced to both the upper side and the lower side of a face to be exposed and an exposure operation is performed. CONSTITUTION:After a main pattern has been exposed, an auxiliary pattern 2 is exposed on the upper part of a wafer by using a beam which is out of focus by displacing the focus of an electron beam. Then, the auxiliary pattern 2 is exposed on the lower part of the wafer by using a beam which is out of focus by displacing the focus of the electron beam. The position in which the auxiliary pattern is exposed is displaced to a direction which is opposite to the auxiliary pattern by using a target position as the center when the focus is displaced upward. Consequently, when a half exposure amount each is given to both beams, the uniform backward scattering intensity of the tittle method is realized, and a uniform pattern is formed.
