Title: Nuclear reactor control rod device
Inventor: OTSUKA MIKIO
IPC: G21C7/20
Filed: 1988-01-18
Abstract: PURPOSE:To eliminate the need for a dashpot ram by using control shades and auxiliary shades which convert kinetic energy to fluid pressure energy, thereby functioning as a buffer in the event of fall of a single control rod. CONSTITUTION:Plural pieces of the movable brake shades 2 which utilize liquid drag and the auxiliary control shades 3 integral with the movable brake shades 2 for improving fluid drag as well as mounting plates 5 and pins 4 for mounting these shades to a control rod 1 which is vertically moved by a control rod driving mechanism 9 are mounted to the upper part of the above-mentioned control rod 1. The restrain of the mounting plates 5 which are held locked by contact with the outer circumference of the control rod driving mechanism 8 is lost when the connection of the control rod 1 to the control rod driving mechanism 9 is lost and the single control rod falls of itself. The control shades 2 and the auxiliary brake shades 3 are then force-opened by the fluid pressure of the liquid sodium flowing in a guide pipe 8 from below to above in the reactor core and the spring force of push springs 7.

Title: Image forming device
Inventor: INOUE MICHIHIRO
IPC: B41J2/455
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To form a smooth image without contriving a high resolution. SOLUTION: In an image forming device employing the so-called overscan exposure method, a main control part 33 selects an optimal light-emitting pattern in compliance with the shape of an image in a single pixel to enter an assignment signal to a semiconductor laser control device 24. The semiconductor laser control device 24 controls a semiconductor laser 25 in such a manner that the intensity of light is changed by the selected light-emitting pattern. A pattern of the constant intensity of light in a single pixel, a pattern ascending over time and a pattern descanding over time are prepared as at least, three light-emitting patterns. Consequently, it is possible to reproduce an image edge part tilted in a main scan direction with high fidelity, without depending on a high resolution.

Title: Production of oxide magnetic thin film magnetic recording medium
Inventor: NISHIMOTO KOUZOU
IPC: G11B5/66
Filed: 1978-01-24
Abstract: PURPOSE: To effectively produce a recording medium whose protecting film is a non-magnetic oxide thin film composed primary of α-Fe 2 O 3  which is superior in durability, but is stable in coercive force and does not cause aging by heat-treating the compound films of multilayer structure.  
     CONSTITUTION: O 2  is introduced into a high vacuum vessel and Fe is evaporated from a vapor source under high vacuum. An oxide magnetic thin film composed primarily of Fe 3 O 4  is formed on the substrate to a thickness of about 1500 Å by a reaction vapor deposition method. Next, the introduction of O 2  is stopped and the thin film of Fe is formed to a thickness of 150 Å under high vacuum. Finally, O 2  is again introduced and Fe is evaporated at a lower rate of evaporation under high vacuum, thus the non-magnetic oxide thin film mainly composed of α-Fe 2 O 3  is formed as a protecting film to a thickness of about 1000 Å. The composite films of such multilayer structure are heat-treated for 1 hour at 250°C in air, after which they are cooled rapidly.

Title: Manufacture of polymerization catalyst and olefin polymerization
Inventor: DONARUDO REINHOORUDO UITSUTO
IPC: C08F4/74
Filed: 1983-01-19
Abstract: A silica hydrogel is contacted with a hydroxy-containing organic compound which is not completely miscible with water but which is sufficiently miscible with water so as to remove water, and thereafter the organic compound is removed by heating in an inert atmosphere prior to activation by heating in air. The heating in the inert atmosphere allows utilizing preferred organic compounds such as C<sub>5</sub> and C<sub>6</sub> alcohols which are desirable from a commercial standpoint because of the easy separation for recycle. In a preferred embodiment, the hydrogel is aged at a pH of 7 to 9 by means of either adding a base or by utilizing a chromium component containing bound nitrogen.

Title: Optical axis regulator for spectrometer
Inventor: MURAHASHI TOSHIAKI
IPC: G01J3/02
Filed: 1980-01-23
Abstract: PURPOSE:To speedily and highly accurately regulate the optical axis of a spectrometer and make it possible readily and precisely determine the sample holding position by providing both an optical axis regulating visible laser beam source and a sample positioning laser beam source for regulating the optical path. CONSTITUTION:When the optical axis is regulated, a rotary reflecting mirror 9 is set at the 45 deg. position and a visible laser beam source 11 is driven. The beam 11a from the visible laser beam source 11 is reflected by the rotary reflecting mirror 9 and travels to a reflecting mirror 3. When the beam 11a is on a regular optical path A, the beam entering through a slit in a mask 10 put on the reflecting mirror 3, through reflecting mirrors 3 and 2, goes out of an incident slit 1a; when the beam does not go out an X-Y axis regulating table 12 is operated to regulate the optical axis. After the optical axis regulation, a visible laser beam source 13 is driven and the angle of a reflecting mirror 14 is changed so that an optical intersecting point PO is formed at the focal position of a condensing lens 5. Thereby, the holding position of a sample 6 can be obtained.

Title: Manufacturing method of tungsten halogen lamp

Filed: 1982-01-20
Abstract: PURPOSE:To carry out reduction of an oxide left over inside a glass tube with fairly lower temperature than ever before as well as to remove almost completely the residual oxide in the glass tube. CONSTITUTION:This method is developed by having an eye to the fact that carbon monoxide (CO) is ever strong in reduction force even in case of low temperature as compared with hydrogen (H), i.e., in the exhausting process of a tungsten halogen lamp, inert gases inclusive of the carbon monoxide and carbon tetrachloride, for example, nitrogen, a mixture of gases comprising argon or nitrogen-argon, etc., are sealed up inside a glass tube which is heated from the outside by a burner and the like, thereby raising the temperature of metal component parts such as a lead wire, etc., inside the glass tube and reducing these oxidated metal component parts inside the glass tube. The formed carbon dioxide gas (CO2) by reaction is exhausted out of the glass tube together with the inert gases and other residual gases.
