Title: Semiconductor device
Inventor: HONMA ICHIRO
IPC: H01L23/522
Filed: 1988-12-22
Abstract: PURPOSE:To prevent a conductive region in an Si semiconductor element from being etched by a method wherein a high-melting point metal or high-melting point metal silicide-Al alloy layer is formed on the surface of a conductive support pillar region, where conductive support pillars are formed, in the Si semiconductor element. CONSTITUTION:Al element isolation insulating film 2 to isolate an Si semiconductor element and an N-channel MOS transistor TR consisting of a gate oxide film 3, a gate electrode 4 and N-type high-concentration impurity diffused layers 5 are provided on a P-type Si substrate 1. Moreover, a high melting point metal silicide layer 6 is formed on the surfaces of the layers 5 and sn Al-high-melting point metal silicide alloy layer 7 is formed on the layer 6. Conductive support pillars 8 containing Al as their main components are formed for connecting with these upper wirings 9. Thereby, in case a reactive ion etching is performed, the possibility of the disappearance of a conductive region in the Si semiconductor element can be avoided.

Title: Optical fiber coupler
Inventor: OSHIMA SHIGERU
IPC: G02B6/28
Filed: 1990-11-29
Abstract: PURPOSE:To accomplish the function of an optical multiplexer/demultiplexer and a directional coupler and to miniaturize an entire system by providing a tapered area formed by bundling three single mode optical fibers, heating the specified position of the bundle of the optical fibers and extending the optical fiber in an axial direction. CONSTITUTION:Three single mode optical fibers 11-13 are arranged in parallel and bundled. The near center part of the fibers is heated so that the respective clads of the respective optical fibers are thermally fused one another and the fused part is extended in the axial direction of the optical fiber to form the tapered area. Then, the light beam of 1st wavelength and the light beam of 2nd wavelength are inputted in a 1st input end 12a. The light beams are distributed and coupled in the optical fiber. However, since the complete coupling length is different between the 1st wavelength and the 2nd wavelength, only the light beam of the 1st wavelength is outputted from a 1st output end 12b by controlling the length of the tapered area in the axial direction and fused shape, and the light beam of the 2nd wavelength is outputted from 2nd and 3rd output ends 11b and 13b. Thus, the optical fiber coupler is allowed to have the function of the optical multiplexer/demultiplexer and the directional coupler.

Title: Luminaire
Inventor: MURASE KANEYUKI
IPC: F21V31/00
Filed: 1993-12-22
Abstract: PURPOSE:To restrain a convection of the air so as to prevent adhesion of dust or the like to a reflection plate. CONSTITUTION:A globular lamp 1 is housed inside of an approximately cup- shaped reflection plate 2, thus constituting a luminaire main body. Needle electrodes 3 are inserted through the reflection plate 2 in a state where the tips thereof project inward of-the reflection plate 2. A plurality of flat electrodes 7 are disposed under and near the lamp 1 oppositely to the needle electrodes 3. The needle electrodes 3 and the flat electrodes 7 are connected to both poles of an AC power source 8, respectively. With application of a high voltage from the AC power source 8, an electric field is generated between both the electrodes. Since this electric field becomes unequal because of concentration to the tips of the needle electrodes 3, dielectric breakdown occurs to generate corona electric discharge. This corona electric discharge partly ionizes substance in the air, thus producing an ion. The ion is moved toward the flat electrodes 7 from the needle electrodes 3 by the electric field while being accelerated, and is collected to form an ion wind, which restrains convection of the wind.

Title: Continuous sheet casting equipment and operation thereof
Inventor: MARUYAMA TETSUO
IPC: B21C47/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent breakage and meandering of a cast sheet by setting plural pieces of looper rolls for controlling tension to outlet side of casting roll and bridle rolls attaching brake mechanism for controlling winding tension. CONSTITUTION:Reason, which tension Tr at outlet side of the casting roll is controlled by applying the looper rolls 8 without using pinch rolls, is because of little influence to the sheet shape by quantity, which is not pinched, in the case of the looper roll 8, and sufficient tension control for controlling prevention of the meandering can do without obstructing. Further, application of the bridle roll 9 attaching the brake 10 as the cast sheet conveying device, is because of that the necessary tension for winding with a coiling machine 11 is given to the cast sheet controlled to low tension by adopting the looper roll 8 for preventing the breakage of sheet.

Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To reduce deterioration in image quality of a color difference signal of a sequentially scanning signal in the case of conducting high efficiency coding and high efficiency decoding. SOLUTION: A conversion controller 107 selects a converter A103 or B104 to convert a 844 signal being a sequentially scanning signal received from an input terminal 101 into a 420p signal where a color difference signal is placed at a desired sample position and provides color difference information relating to the sample position of the color difference signal obtained by the selected converter A103 or B104 to a color difference information recorder 106. The color difference information recorder 106 multiplexes the color difference information onto the converted signal and provides an output of the result. The color difference information from the conversion controller 107 is multiplexed at the color difference information recorder 106 to allow a plurality of kinds of signals are sent through one and same transmission line.  In the case of applying high efficiency coding to the transmitted signal, proper conversion is applied to the color difference signal based on the color difference information and provision of undesired deterioration is avoided.

Abstract: PURPOSE:To obtain a high speed Bi-CMOS circuit by providing a voltage correction means between the base of a transistor(TR) receiving the output of the Bi-CMOS circuit and a power supply, and converting a level of the Bi-CMOS circuit to an ECL level. CONSTITUTION:When an L level is inputted to a Bi-CMOS circuit 12, a P- channel MOS TR MP1 and a TR Q1 are turned on and a base voltage of a TR Q3 is lowered to 0.8V by a base-emitter level VBE of the TR Q1. In such a case, N-channel MOS TRs MN1, MN2 and a TR Q10 are turned off. On the other hand, when an H level is inputted to the Bi-CMOS circuit 12, since the TR-MN1, MN2 and the TR Q10 are turned on, the base voltage of the TR Q3 is equivalent to the clamped level of diodes D1, D2 and SD1 and goes to -2.0V. Thus, the level of the Bi-CMOS circuit 12 is converted into a level of an ECL circuit 3.
