Title: Crt display
Inventor: KITO KOJI
IPC: G09G1/00
Filed: 1994-04-26
Abstract: PURPOSE:To provide a CRT display in which the correction of landing and the correction of luster rotation can be compatible. CONSTITUTION:In the figure, a geomagnetism sensor 5 detects the change of the geomagnetism in the axial direction of a CRT 1, and a control circuit 6 lets currents flow to geomagnetism correction coils 3 and 4 in the direction of negating the change of geomagnetism, and performs feedback control so that the output of the geomagnetism sensor 5 may be constant. The geomagnetism correction coil 3 mainly corrects the landing, and the geomagnetism correction coil 4 mainly corrects the luster rotation. Hereby, a CRT display, which can get always favorable color reproductivity and screen distortion performance without depending on the change of magnetism, can be materialized.

Title: Manufacturing method for semiconductor device
Inventor: MIZUKOSHI KANJI
IPC: H01L23/31
Filed: 1978-07-18
Abstract: PURPOSE: To surpress an increase of a reverse leak current of a pn junction by controllably giving a small amount of organic chelate material to the full surface of a semiconductor substrate by a evaporation.  
     CONSTITUTION: When Arizarin is contained as an organic chelate material in a seal casing of a semiconductor device, a metallic ion disappears because the arizarin is changed to an arizarin lake in reaction with the metallic ions. However, when a much amount of arizarin may be existed therein, an errosion is caused in reaction with only the metallic ion, but also a bonding wax material for a semiconductor or a solder electrode. Meanwhile, a semiconductor substrate containing a pn junction and a small amount of arizarin are accommodated in the sealed casing to be maintained in the air or vaccum atmosphere, heated at 80 to 430°C to vaporize the arizarin and be attached to a mesa surface. According to this process, only slight organic chelate material is added to the pn junction, and the reverse current increase can be restricted freely and a metallic errosion would not be caused.

Title: Nonspherical micro-lens and its manufacture and optical fiber coupler, condensing optical system, optical element, semiconductor laser light source and image device utilizing nonspherical micro-lens
Inventor: AOYAMA SHIGERU
IPC: G02B6/32
Filed: 1988-04-13
Abstract: PURPOSE:To obtain a nonspherical micro-lens almost free from axial and chromatic aberrations with high accuracy by applying a resist to the surface of a base plate thicker than the maximum thickness of the lens and developing after drawing a prescribed pattern on the resist. CONSTITUTION:An electronic beam resist 4 is uniformly applied to the surface of a base plate 3. Before applying the resist 4, a conducting film (e.g., ITO) 2 is formed on the base plate 3 in order to cause the electric charges charging electrostatically to the resist 4 at the time of drawing a prescribed pattern with an electronic beam to escape. Since the thickness d0 of the resist 4 must be thicker than the thickness of a nonspherical micro-lens to be formed, resist applying and baking processes are repeated several times so that the thickness of the resist 4 can become, for example, about 10mum. Then, after drawing the pattern of the nonspherical lens to be produced on the resist 4 by using an electronic beam drawing device, the lens is developed. Thus a nonspherical micro-lens which is small in size and light in weight, but free from aberration can be obtained.

Filed: 1990-04-04
Abstract: PURPOSE:To accomplish measurement with high accuracy in a proper state for a tested eye using a correcting lens by disposing a polarization mirror on the optical axis, and guiding light from a light source to the eyeground of a tested eye through the polarization mirror. CONSTITUTION:A projection system 1 comprises a light source 4 and a polarization mirror 5 for reflecting luminous flux 11 of the light source toward a tested eye 3. A photo detecting system 2 comprises an objective lens 8 and a photo detecting element 9, wherein the luminous flux 10 reflected by an eyeground 7 and transmitted through a polarization mirror 5 is guided onto the photo detecting element 9. The polarization mirror 5 transmits 100% P components and reflects 100% S components 3. When the eye refractivity exceeds a proper measuring range, the eye refractivity of the tested eye 3 is corrected by a correcting lens 16. The reflection of the luminous flux 11 is caused by inserting the correcting lens 16 in an optical path. The luminous flux which reaches the correcting lens 16 is formed by only S component due to the operation of the polarization mirror 5. Accordingly, all the reflected light is reflected to the light source 4 side by the polarization mirror 5, and it is only P components caused by reflection on the eyeground 7 through the correcting lens 16 that reaches the photo detecting element 9.

Abstract: PURPOSE:To execute stable development with decreased troubles of a transportation system with a prolonged life of a developer by inserting printing plates directly into the developer from the lateral side of a developing tank, linearly transporting these printing plates and retreating the printing plate from the lateral side. CONSTITUTION:Only the air inflow and outflow port 3 is held open and the other ports are held closed and the developer is supplied from a developer supply port 2 into a developing machine 1. A sensor operates to open a shutter 5 when the front ends of the printing plates approach an insertion port 4 after the developer is heated to a prescribed temp. The printing plates are then developed while moving in the developing machine 1 and emerges out of an outlet 4'. The liquid level of the developer is lowered by carry over of the developer by the printing plates when the number of the processed sheets increases. The development is stopped and replenishment of the liquid is executed when the liquid level approaches the transportation plane. Namely, the printing plates are inserted from below the liquid level of the developer and are developed while the printing plates are moved horizontally. The printing plates are horizontally moved as they are until the plates are discharged. Then, the fatigue of the developer by air and the evaporation of the moisture are lessened and the development is executed without bending the printing plates.
