IPC: H01J61/28
Filed: 1983-04-15
Abstract: PURPOSE:When containing a light emission tube encapsulated with metal body for forming amalgam, to maintain high efficiency of light output in wide temperature range by employing an enclosed casing while constructing with synthetic resin material having lower heat penetration than glass. CONSTITUTION:Amalgam forming metal body 14 is encapsulated in a light emission tube 6, and temperature rise at the circumference of said tube 6 will cause coupling of said metal 14 with excessive mercury in the tube to form amalgam thereby lighting under high temperature environment will hardly cause mercury vapor pressure rise thus to prevent drop of light output. Furthermore the casing 4 is made of synthetic resin having lower heat penetration to provide an enclosed structure thus to confine heat produced from said tube 6 at initial lighting stage efficiently in an enclosed space 5 while the protect the temperature in said space 5 from influence of external temperature.

Title: Display system of tape residual time
Inventor: NASHIKI NOBORU
IPC: G11B27/11
Filed: 1980-05-22
Abstract: PURPOSE:To increase the accuracy of a display system of tape residual time, by displaying through a subtraction performed with a prescribed time interval when an error is within a specified time and with a time interval longer or shorter than a prescribed time when the error is more than a specified time respectively. CONSTITUTION:The residual time obtained through an operation is compared with the residual time that is presently displayed. A display is carried out by giving a subtraction to the residual time presently displayed with a prescribed time interval when an error is within a specified time and with a time interval longer or shorter than a prescribed time interval when the error is more than a specified time respectively. For instance, the data of the rotating speed and the thickness of a tape is supplied through input/output circuits I/O2 and I/O3, and the residual time is calculated by a memory ROM and an operational CPU. A program to correct the error is set up in the ROM by performing a count-down from the residual time presently displayed with every second by a second when the error is within a specified time with every second in, e.g., by 1.1sec when the rror is more than a specified time respectively.

Title: Fuse
Inventor: HORIBE KINYA
IPC: H01H85/11
Filed: 1988-03-23
Abstract: PURPOSE:To prevent fusing performance from lowering due to aging and oxidation and improve durability by using an oxidation resistant metal as a low melting point chip. CONSTITUTION:An oxidation resistant, low melting point metallic chip 3 is placed on a fusing section of a meltable metallic conductor 2. While copper (of the melting point 1083 deg.C) is usually used as the metal for the meltable metallic conductor, tin-plate copper, aluminum, or aluminum alloy can also be used. The fuse generates heat by an excessive current, the heat melts the low melting point chip, the molten chip diffuses and forms alloy with the meltable metallic conductor, and the alloy melts. As a result, the fuse melts. Because the oxidation resistant metal is excellent in the oxidation resistance, its surface is not oxidated even if it is used for a long period time and prevents the sensitivity of the fuse from lowering.

Title: Liquid crystal display element
Inventor: KINUGAWA KIYOSHIGE
IPC: G09F9/30
Filed: 1984-04-06
Abstract: PURPOSE:To execute uniform gap control between electrode substrates, and also to prevent air bubbles from being generated when a titled element is allowed to stand at a low temperature, by providing an interval holding material between the opposed electrode substrates, and making an outside diameter of an interval controlling fine particle smaller than the outside diameter of an interval controlling fine particle in a sealing material. CONSTITUTION:The first glass fiber 3 whose outside diameter is about 7mum is dispersed and placed between an upper electrode substrate 1 and a lower electrode substrate 2, and also the second glass fiber 5 whose outside diameter is larger than the first glass fiber 3 is mixed in a sealing material 4 and an interval holding material 7. In this state, when the upper electrode substrate 1 and the lower electrode substrate 2 are stuck to each other by applying a uniform weight, both the electrode substrates 1, 2 are bent because an area of an effective display surface 6 is wide, the first glass fiber 3 dispersed and placed between both the electrode substrates 1, 2 comes into contact, and a uniform gap P readjusted by the outside diameter of the first glass fiber 3 is formed. On the other hand, an area surrounded by the sealing material 4 and the interval holding material 7 is fixed in a state that it does not contact the first glass fiber 3, because its area is narrow.

Abstract: PURPOSE:To prevent damage of article, deterioration in characteristics and the like from occurring and the predetermined portion of the article from being covered by resin by a method wherein a covering member of a passage, through which resin is poured to the predetermined portion of the article to be embedded, is pressed by a mold. CONSTITUTION:A pallet 12 is die-bonded onto a lead 13b by means of a bonding layer composed of silver paste, soft solder or the like. Resin 22 is applied over the whole top surface of the pellet 12, excluding the portion near bond pads 15a-15d and solidified. The leads 13a-13d and the resin are pressed from above and below by clamping a mold 23 consisting of a top half 23a and a bottom half 23b. Finally, resin is poured in the mold 23 in order to transfer- mold. Because magnetism sensing parts 14a-14d are covered by the resin 22 which is also pressed down by the top half 23a, the resin 16 does not flow in the magnetism sensing parts 14a-14d.

Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To obtain excellent color developability and transparency even if either of recording paper and OHP is subjected to image formation by incorporating a high concn. of chromatic coloring agents, binder resins and metal oxide particulates into a master batch. SOLUTION: The master batch for color toners contg. the high concn. of the chromatic coloring agents, binder resins and metal oxide particulates is used. This master batch is obtd. by mixing raw materials, melting and kneading the mixture composed thereof and pulverizing the mixture after cooling. More specifically, the chromatic coloring agents, the binder resins and the metal oxide particles are mixed by a device, such as Henschel mixer, which acts shearing force on the material to be treated. The disintegration of the secondary flocs of the chromatic coloring agent is induced as a result of the stresses by the shearing force in this mixing stage. This mixture is then subjected to melting and kneading, then to pulverizing after cooling, by which the master batch is obtd.  The large shear acts on the coloring agents in consequence of the high concn. of the chromatic coloring agents in the kneaded mixture and the coloring agents are finely dispersed in this melting and kneading stage.
