Title: Variable stereoscopic microscope
Inventor: MATSUMURA ISAO
IPC: G02B27/22
Filed: 1984-09-01
Abstract: PURPOSE:To change the degree of stereoscopic observation easily by arranging a light flux polarizing means for changing the interval between the base lines of a pair of stereoscopic observation optical systems by turning them between these optical systems and an objective lens. CONSTITUTION:Light from an object point O is passed through the objective lens 1 and reflected by the reflecting surfaces 2a, 2b of a square reflection prism 2 and the reflected components are made incident upon zoom lenses 4a, 4b through mirrors 3a, 3b and sent to eyepiece optical systems Ea, Eb. When the prism 2 is turned by 90 deg., the light from the objective point O is passed through the objective lens 1 and then reflected by the reflecting surfaces 2c, 2d of the prism 2 and respective reflected components are sent to the optical systems Ea Eb through the mirrors 3a, 3b and the zoom lenses 4a, 4b respectively. The light flux axes La, Lb, Lc, Ld on the prism 2 are that on the reflecting surfaces 2a, 2b, 2c, 2d and the interval of the base lines of the Lc and Ld is set up comparatively larger than that between the La and Lb. Thus, the angle of stereoscopic observation can be changed by changing the interval between the base lines of respective light flux components on the reflecting prism 2.

Title: Flexible pipe covered by resin
Inventor: HIGUCHI HIROSHI
IPC: B32B15/08
Filed: 1999-06-29
Abstract: PROBLEM TO BE SOLVED: To facilitate the inspection of the existence/absence of the hole made by the strike in of a nail, without hurting a flexibility and durability by forming a resin layer by polyolefin system resin with the tensile elastic rate of a specific range. SOLUTION: A flexible pipe 3 covered by a resin is formed by covering a corrugated pipe 1 made of for example thin stainless steel by a resin layer 2. Here, the resin layer 2 is formed by polyolefin system resin whose tensile elastic rate is 590-1400 kg/cm2, for example ethylene-acrylic ester copolymer and made by mixing properly the additive such as an anti-weathering material, fire retardant agent, anti-oxidant and colorant. In the polyolefin system resin with the tensile elastic rate of this range, when a hole is made on a metal flexible pipe 1 by striking the nail in, while ensuring a flexibility sufficiently, the end of broken resin layer 2 hardly blocks the clearance between the resin layer 2 and nail. Therefore, it is easy inspect the existence/absence of the hole made by the strike in of the nail without hurting the flexibility and durability.

Title: Thin film forming device
Inventor: MORI EISAKU
IPC: C23C14/24
Filed: 1986-08-06
Abstract: PURPOSE:To prevent the fall of the deposits on an electrode for improving potential distribution into and onto a crucible and filament with a thin film forming device by providing said electrode inserted between grids and the crucible so as to crown and incline. CONSTITUTION:A material 2 for vapor deposition in the crucible 1 is heated to form vapor 4 which is ejected from a nozzle 3 into a vacuum so as to collide against the ionized electrons drawn out to the grids 9 and to form the ions of positive charge. The vapor 4 formed as the positive ion is accelerated by an acceleration electrode 13 and is deposited by evaporation on a substrate 14 by which a vapor deposited film 15 is formed. The electrode 21A for improving the potential distribution inserted between the grids 9 and the crucible 1 of the device which makes the above-mentioned operation is provided to crown and incline. The materials flow to the peripheral part of a lower level and are thus prevented from falling into the crucible 1 and onto the filament 5 even if the vapor sticks and deposits on the electrode 21a. The staining of the device is thereby prevented without generating electric discharge between the crucible 1 and the filament 5.

Title: Method and device for eliminating edge part of substrate covering film
Inventor: SANADA MASAKAZU
IPC: H01L21/027
Filed: 1995-06-26
Abstract: PURPOSE: To reduce the protuberance of a covering film and the non-uniformity in elimination width by relatively increasing the amount of supply of a treatment liquid in the initial process for eliminating the edge part of the covering and eliminating the most part of the covering edge part and then reducing the amount of supply of the treatment liquid and eliminating residue. CONSTITUTION: A substrate W sucked and retained by a suction spin chuck 1 is rotated by an electric motor 3 via a rotary shaft 2. A scattering-preventing cup 4 for preventing the scattering of such liquid as the treatment liquid is arranged around the suction spin chuck 1. First, the substrate W is rotated at a speed for edge rinsing. Then, a flow adjustment valve 14 is adjusted to set the flow to a relatively large value. The purpose of the elimination of the covering edge part in a large flow is to eliminate the most part of the covering at a part to be eliminated (namely, a rough elimination). When the elimination in a large flow is completed, the flow adjustment valve 14 is adjusted and the amount of supply of the treatment liquid is switched to a small flow.  The purpose of the elimination in the small flow is to eliminate residue at the time of elimination in large flow with a precise finish.

IPC: H01J1/14
Filed: 1983-09-30
Abstract: PURPOSE:To inhibit evaporation of the reducing agent from the back side of the substrate metal so as to ensure long-life of the cathode by forming an oxide layer of alkali earth metals on the back side of the substrate metal. CONSTITUTION:An electron emitting oxide layer 9 composed of oxides of alkali metals is formed on the right side of the substrate metal 8, while another oxide layer 21 composed of oxides of alkali earth metals such as oxides of Ba, Sr, or oxides of Ba, Sr, Ca is formed on the back side of the same substrate metal 8. Thus formed are the internal oxide layers 22, 23 which are 2-5mum deep from the right side or back side of the substrate metal 8. As a result, diffusion control layers 25, 25 composed of BaO, MgO and SiO2 are formed almost in parallel with the faces of the right or back side of the substrate metal 8, between the internal oxide layers 22, 23 and the inside 24 of the substrate metal 8 whose reducing agents Mg, Si, are not yet oxidised. Since these diffusion control layers 25, 25 inhibits the diffusion of Mg, Si and O, the loss of Mg, Si from the inside 24 of the substrate metal 8 can be prevented, and furthermore, the evaporation of Mg from the back side is suppressed. Thus the reducing agents contained in the inside 24 of the substrate metal 8 is effectively utilized so as to maintain the life of the cathode long.
