Patent JP-H1167055-A (JP)
Title: Thermoelectron emitting filament and its manufacture
Inventor: MUROTA MASAO
IPC: H01J1/14
Filed: 1997-08-21
Abstract: PROBLEM TO BE SOLVED: To reduce sputtering effects and generation of whiskers to extend life by depositing a plurality of metallic films from inside to outside on the surface of polycrystal tungsten or a tungsten-rhenium alloy from the end of a filament to a supporting part, in the order of melting point, and alloying them together. SOLUTION: Using polycrystal tungsten 1 or a tungsten-rhenium alloy as a shaft, a thin film 3 of platinum and a thin film 5 of gold, both including platinum black of 500 Å or more, are formed on the shaft, with a relatively thick layer of aluminum 5 formed thereon to provide a three-layered structure. In an end thermoelectron emitting part A, the polycrystal tungsten 1 and the thin film 3 of platinum, the thin film 3 of platinum and the thin film 4 of gold, and the thin film 4 of gold and the aluminum 5, are alloyed together through slow heating. In this case, since the polycrystal tungsten is alloyed by covering with a metallic film, the tungsten is not oxidized and a filament resists breaking, leading to longer life and eliminating getter effects, so that the filament becomes usable in a low vacuum.

Inventor: GUSTAFSON THOMAS L
IPC: F21S4/00
Filed: 1996-08-27
Abstract: PROBLEM TO BE SOLVED: To make a light strip humidity-impermeable, by completely endlosing first and second bus elements and an LED by extrusion soft sticking plastic material. SOLUTION: An LED circuit device 12 is installed which is enclosed in a thermoplastic housing 14 having one integral constitution having no inside gap. The thermoplastic housing 14 is preferably using polymer material having low water-vapor permeability, such as ionomer resin, high-density polyethylene, or polychlorotrifluouroethylene. A resistor 24 and a luminous diode 26 are joined, so as to function to a printed circuit base board track 22 between conductive bus contact pieces. A light strip can be turned into humidity impermeability by thus completely enclosing first and second bus elements and an LED, by extrusion soft sticking plastic material.

Title: Digital av data transmission unit, digital av data reception unit, digital av data transmission/reception system and medium
Inventor: NISHIMURA TAKUYA
IPC: G06F21/10
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To appropriately perform data communication while being immune to forgery or alteration and considering the importance of data or class of a recognition method by receiving an authentication request and performing authentication based on one kind of authentication rule selected out of a means storing plural authentication rules on the side of transmission based on the discriminated result of a data importance discriminating means. SOLUTION: When an authentication requesting means 12 receives the authentication request, a data importance discriminating means 3 discriminates the importance of AV data 2 to be transmitted and classifies them according to CGMS values. A transmission side authentication selecting means 6 sends the optimum authentication rule, which is selected out of a means 5 storing plural authentication rules on the side of transmission, to a digital AV reception unit TV9. At a digital AV transmission unit STB1, the same authentication rule as the selected certification rule is selected and a reception side authentication means 13 and a transmission side authentication means 7 mutually perform the authentication.  When the authentication is made successful, the AV data 2 to be transmitted are enciphered and transmitted while using a work key Kco16 and the received enciphered data are deciphered by a work key Kco17.

Then a reading device 13 reads the document data and a printer 14 prints the reception data. These data are transferred by a MODEM 17. The document used with this facsimile equipment includes an address column containing plural address codes, a message column and a memo column. Then this document is transmitted from the transmission side. At the reception side where the document is received, the addresses written in the address column are extracted under the control of the CPU 10 and then printed together with the message. Thus the accuracy is secured for transmission and reception.

Filed: 1985-10-11
Abstract: PURPOSE:To efficiently form a uniform and beautiful colored layer on the surface Al by immersing an Al material subjected to an anodic oxidation treatment in an electrolytic coloring liquid and impressing a specific AC voltage thereto. CONSTITUTION:The Al or Al alloy material is anodized by an ordinary method using an acidic soln. such as sulfuric acid, oxalic acid or sulfamic acid to form an anodized film on the surface.

Inventor: HIRONO KIMIO
IPC: G01N21/95
Filed: 1998-08-07
Abstract: PROBLEM TO BE SOLVED: To simply discriminate the quality of an optical stamper by irradiating the optical stamper to be inspected with a laser beam through the transparent substrate overlapped onto the stamper and the transparent substance interposed between the stamper and the substate and detecting the reflected laser beam through them. SOLUTION: A glass substrate 207 is preliminarily stuck to an optical disk stamper 200 being a measurement object by interposing a transparent resin or a photosetting resin or a ultraviolet curing resin 210 between them. The beam which transmits the glass substrate 207 and which is reflected on the signal surface of the optical disk stamper 200 transmits the substrate 207 again to be made incident on a objective lens 206. After the reflected beam transmits the lens 206, the light quantity of the reflected beam is detected by a photodiode 208. Then, the quality of the stamper is discriminated by detecting an HF signal and a tracking error signal. A reproduction characteristic inspection result equivalent to that of the optical disk produced from this optical disk stamper is obtained from the same reproduction principle as that of an optical disk.

Title: Substrate type optical switch
Inventor: SAKANO TATSUYA
IPC: G02F1/313
Filed: 1990-08-28
Abstract: PURPOSE:To reduce the absorption loss of free carriers by providing a current confinment layer above a compound semiconductor substrate and an optical waveguide layer above the current confinment layer, and composing the current confinment layer of a crystal layer where a current confinment part is selectively removed. CONSTITUTION:The current confinment layer 32 is provided above the compound semiconductor substrate 22, a 1st semiconductor layer which is not doped is provided above the current confinment layer 32, and the optical waveguide layer 34 is provided above the 1st semiconductor layer. In this case, the current confinment layer is composed of the crystal layer where the current confinment part is selectively removed and the current confinment part consists of the current confinment layer 32 and an opposite conduction type 2nd semiconductor layer. Consequently, carriers which are injected into a waveguide type optical switch flow as a narrow laminar current across the optical waveguide layer 34 toward the current confinment part, so that carriers are concentrated on only the part of the current confinment part which is required for switching. Therefore, the current confinment part confines the injected current effectively to an inflow and outflow area without outward dispersion. Consequently, the absorption loss of the free carriers can be decreased.

Title: Multiple steam water separator
Inventor: SHIINA KOJI
IPC: B01D45/12
Filed: 1992-08-25
Abstract: PURPOSE:To improve the steam/water separator capability for high temperature water steam system two-phase flow and reduce pressure loss by multiplying the steam/water separator, making the bottommost swirl vane angle small, upper one's angle large and the topmost swirl vane angle largest. CONSTITUTION:A steam/water separator is in three steps. Since ascending steam/water two-phase flow from a stand pipe 14 is slug flow with small void fraction, the angle of swirl vane 15a is made small to mainly separate liquid block in this separator 11a and pressure loss is medium grade. Since the above is anular flow with large void fraction, the angle of swirl vane 15b is made slightly large to mainly separate liquid film in this separator 11b and pressure loss is medium grade. Since the topmost is mist flow with large void fraction, the angle of swirl vane 15c is made largest to mainly separate liquid drops in this separator 11c and pressure loss is small. In this manner, the arrangement of the separators 11a to 11c and the angles of the swirl vanes 15a to 15c are determined accordingly to the flow regime of steam/water two-phase flow and the total pressure loss is reduced and the separation capability is improved.
