IPC: H03M7/30
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To accelerate encoding speed by providing a tree constructing means which constructs tree representation of a coefficient and a tree encoding means which encodes the tree representation. SOLUTION: A coefficient encoder 1305 fetches corresponding data 1304 and outputs encoded data 1306.

Abstract: PURPOSE:To strengthen the bonding power on the polycrystalline silicon/silicide interface for preventing the release from occurring by a method wherein, after doping the polycrystalline silicon with an impurity, a natural oxide film is etched away within a silicide deposition device to deposit the silicide continuously without exposing it to the atmosphere. CONSTITUTION:After forming a gate oxide film on a silicon substrate, a polycrystalline silicon film 3 is deposited to be doped with an impurity however, a spontaneous oxide film 4 is deposited on the polycrystalline silicon. This natural oxide film 4 causing the release of silicide shall be removed. Thus, the spontaneous oxide film is removed within a silicide depositing device to deposit the silicide continuously without exposing it to the atmosphere. In order to remove the spontaneous oxide film 4, HF vapor is suitable but carbon halogenide, sulfur base gas are also applicable. The polycide gate thus formed having the high bonding power on the polycrystalline silicon/cilicide interface shall be subjected to no release at all even after the later heat treatment and oxidization processes.

Abstract: PURPOSE:To measure the temperature at a junction of a multibeam-type LD effectively by adopting a variable pulse current source for one of variable direct current sources and by measuring a direct-current light emission characteristic and a pulse light emission characteristic of the LD. CONSTITUTION:Multibeam-type LD 2 is driven by variable direct current source 1A, 1C and 1D and a variable pulse current source 1P. Laser beams 2E to 2H of the LD 2 are applied in a state of a synthesized beam onto a photodiode 3. Accordingly, the laser beams of direct-current light outputs driven by the variable direct current sources 1A, 1C and 1D and the laser beam of a pulse light output synthesized in the direct-current light outputs are obtained and the laser beams of the direct-current light outputs and the laser beam of the pulse light output are measured by a measuring device 5. Since two kinds of measured outputs are obtained, a heated state of the inside of the LD 2 can be measured in a condition that a laser oscillation element integrated inside the LD 2 is driven by a plurality of direct current sources, while a light output characteristic can be measured, of course, in respect to only one specified laser beam.

Title: Semiconductor device
Inventor: KOYAMA HIROSUKE
IPC: H01L39/14
Filed: 1987-10-30
Abstract: PURPOSE:To protect device performance characteristics from degradation due to a bend of the course of carriers under the influence of a current in a superconducting wire by a method wherein a current is allowed to flow in a superconducting wiring layer so that carriers in a MOS transistor channel may be attracted to the surface of a semiconductor substrate. CONSTITUTION:On a gate electrode 5, there is an insulating layer 7, whereon there are superconducting wiring layers 6a and 6b sandwiching another insulating layer 8. The superconducting wiring layers 6a and 6b are vertically connected at their ends by contact 6c and 6d which are again superconducting wiring layers, which results in a closed circuit. An electron current E in a channel 3 is opposite in flow direction to an electric current C in the superconducting wiring layer 6a. Accordingly, the current in the channel 3 is flow direction same as the current in the superconducting wiring layer 6a. In such a design, electrons are bent toward the surface of a substrate 1 on their way from a drain 2a for a source 2b. Electrons therefore will not travel deep into the substrate 1, which protects a semiconductor device from degraded performance characteristics.

Abstract: PURPOSE: To improve operability and safety by energizing covers to positions to cover inserting holes when a plug is not inserted in the plug electrode inserting holes. CONSTITUTION: Tip parts of electrodes of a plug 25 are pressed against planes or curved surfaces 14c and 15c formed on projecting parts 14b and 15b of an upper side cover 14 and a lower side cover 15. Then, the covers 14 and 15 are slidingly moved in parallel to a surface of a plate 11, and inserting holes 17 are exposed, and the electrodes of the plug are inserted in the inserting holes 17. Therefore, since the electrodes of the plug can be inserted into the inserting holes 17 with one hand, operability is improved. Here, when the electrodes of the plug 25 are not inserted, the covers 14 and 15 are energized to positions to cover the inserting holes 17 by springs 18, and cover the inserting holes 17.  After they are inserted, a clearance generated between the plug and a surface having the inserting holes 17 is covered from the vertical direction with the projecting parts 14b and 15b. Therefore, since erroneous insertion of a metallic piece or the like is prevented, safety is improved.

Title: Method of applying radiation curable resin
Inventor: MASUHARA KENICHI
IPC: B05D1/36
Filed: 1985-12-09
Abstract: PURPOSE:To enhance the close adhesiveness of a film by simple pretreatment, by using an aqueous polyacrylic acid solution in pretreatment and irradiating radioactive rays having intensity reaching the pretreatment film in curing a radiation curable resin. CONSTITUTION:Because polyacrylic acid used in pretreatment has a polar group and an ethylenic double bond, a polyacrylic acid film is strongly and closely adhered to a metal plate so that the polar group is oriented to the surface of the metal plate. When radioactive rays having intensity reaching the polyacrylic acid film are irradiated in curing the radiation curable resin applied onto said film, the ethylenic double bond generates a radical by said radioactive rays and brings about the radical polymerization of the radiation curable resin to be chemically bonded to said resin. Therefore, the radiation curable resin is closely adhered to the metal plate through the polyacrylic acid film.
