Title: Semiconductor light emitting element, its electrode, and its manufacture
Inventor: KAMAKURA TAKANOBU
IPC: H01L21/28
Filed: 1996-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable inexpensive electrode which can efficiently fetch light from an active layer as an ohmic electrode for semiconductor light emitting element, a semiconductor light emitting element using the electrode, and a method for manufacturing the element. SOLUTION: Electrodes for semiconductor light emitting element have laminated metallic thin films 2 and 4 formed on a pellet 1 having double heterojunctions and a layer containing oxygen at a high concentration or an oxide layer 3 formed, between the thin films 2 and 4 by annealing the thin film 2 and high electric conductivity and light transmissivity required for the electrode are obtained from the multilayer effect of the thin films 2 and 4 and layer 3. A semiconductor light emitting element using the electrode has high luminous efficacy and high reliability and can be reduced in cost. In a method for manufacturing the element, an electrode structure can be obtained stably by forming the oxide film 3 between the metallic thin films 2 and 4 by annealing the thin film 2 in an atmosphere containing oxygen after the thin films 2 and 4 are formed.

Title: Encoding method and encoder
Inventor: BOYCE JILL MACDONALD
IPC: H04N7/24
Filed: 1999-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a method for adding recovery information to an inter-frame encoding video for the purpose of protecting video quality from packet loss. SOLUTION: An inter-frame encoding video signal uses a data division function for dividing a video stream into a high priority part 104 and a low priority part 105. After that, systematic forward error/deletion correction encoding is executed only for data of the high priority part 104. High priority part data which are forward error/deletion corrected and low priority part data which are not forward error/deletion corrected are combined into be a packet, transmitted to a reception side through the same network and decoded there. Depending upon a degree of protection for an error or a deletion provided by a specific forward error/deletion correction(FEC), loss of the packet including the high priority part data is corrected by the data where there is no loss in the high priority part.

Title: Manufacture of semiconductor device
Inventor: MIYAJIMA MOTOMORI
IPC: H01L21/31
Filed: 1989-11-17
Abstract: PURPOSE:To prevent a step from occurring in a boundary between an element isolating region and an element forming region and a recess from occurring at the center part of the element isolating region by a method wherein a buried material on a protrusion is finally removed through a polishing method. CONSTITUTION:A polycrystalline silicon film 14b is formed on an oxide film 13 buried in a groove 10a, and only the oxide film 13 on a protrusion 15 is finally removed through a polishing method. By this setup, a step, which is apt to occur in a conventional process that is carried out through a full face controlled etching method, is restrained from occurring in a boundary between an element forming region and an element isolating region, and even if the groove 10a is long in a lateral direction, the groove 10a is not subjected to a polishing process, so that a recess hardly occurs at the central part of the element isolating region.

Title: Molten metal storing container
Inventor: TAKI CHIHIRO
IPC: B22D41/02
Filed: 1987-11-27
Abstract: PURPOSE:To extend the service life of a molten metal storing container by forming a blowing stock layer consisting of a powder refractory stock and convertor slag layer by superposing them alternately on the inner side surface of a refractory brick piece. CONSTITUTION:A coating layer 24 is formed at the inner side of the refractory brick 14 consisting of the inner lining brick 12 of a molten metal storing container 10. This coating layer 24 is composed of the blowing layers 26, 30, 34 consisting of a refractory brick powder body and the layers 28, 32 consisting of a convertor slag. Due to the refractory brick powder body containing no C, the adhesion of the blowing layer 26, 30, 34 becomes better even to the refractory brick 14 and convertor slag layer 28, 30 as well and the coating layer 24 is strongly adhered to the refractory brick 14. The coating layer 24 can thus be formed thicker, hence the service life of the molten metal storing container 10 is extended.

Abstract: PURPOSE:To detect dirt of a charging terminal and to attain warning display by providing a circuit detecting a contact resistance between charging terminals and a means applying warning display when the detected contact resistance exceeds a prescribed limit to a mobile station. CONSTITUTION:A voltage detection circuit 10 in a mobile station 2 sets conditions such as current consumption of a station 2 different from each product, a current by standby and talking time and a change in the charging current due to a voltage change in the charging battery 3 or the like. Then while a change in the charging current flowing between charging terminals 4, 5 in each case is corrected, a contact resistance 9 between the terminals 4, 5 is calculated from the terminal voltage at the terminal 5. Thus, when the terminal voltage at the terminal 5 exceeds a prescribed limit, that is, the resistance 9 between the terminals 4, 5 exceeds a limit, the circuit 10 lights a light emitting diode 11 and sends a signal. Thus, the diode 11 is lighted and the user recognizes it that the terminals 4, 5 are dirt by observing the lighting and the battery 3 is charged properly by cleaning the terminals 4, 5 to remove the dirt.
