Title: Combustor of gas turbine
Inventor: YAMANAKA CHIKAU
IPC: F23R3/40
Filed: 1983-09-21
Abstract: PURPOSE:To efficiently and smoothly burn catalyst by enhancing catalyst combustion reaction by burying a metal piece having good thermal conductivity in a ceramic wall of a honeycomb structure catalyst made of ceramic. CONSTITUTION:Mixture gas of fuel and air is flowed in a cell 8 opened at both ends. Metal piece 10 is filled in a cell 9 sealed at one end. When the mixture gas of fuel and air is now flowed, a catalytic combustion occurs so that the temperature of the catalyst increases toward the downstream side, and the wall temperature of the ceramic having high temperature at the downstream of the catalyst is transmitted to the filled metal piece. Since the metal has high thermal conductivity, the heat is moved from the downstream side of the upstream side in the metal piece. Since the temperature difference exists between the piece and the ceramic at the upstream side, the heat is, on the contrary, flowed from the metal to the ceramic. Accordingly, the axial temperature distribution becomes uniformly higher as compared with that made of only ceramic, thereby accelerating the catalytic combustion reaction.

Filed: 1986-07-23
Abstract: PURPOSE:To obtain a low-cost and small-size printer, by a method wherein two sets of thermal head and ink ribbon cassette are mounted on a carriage axially along a platen so that a printing operation is conducted with one of the sets when the carriage moves forward and with the other when the carriage returns. CONSTITUTION:When a carriage 3 moves forward, printing is conducted with one set of a thermal head 7 and an ink ribbon cassette 9; when it returns, printing is carried out with the other set of a thermal head 8 and an ink ribbon cassette 10. In this case, since the two ink ribbon cassettes 9, 10 are disposed axially along a platen 1, the need for shifting the ink ribbon cassette in the forward/return of the carriage 3 in the prior art is eliminated; thus, a printing direction can be smoothly changed to enhance a printing speed. Additionally, since the need for an elevator mechanism for the up/down operation of the cassette is eliminated, the structure on the carriage is simplified and the need for the travel space for the cassette is eliminated thereby realizing a small-size printer.

Abstract: PURPOSE:To prevent adverse effect such as sound fluctuation or the like by changing over a gain adjusting resistance of a sound output section by a switch attached to a socket for inputting a DC power supply in operating a television receiver or the like by means of the DC power supply. CONSTITUTION:Since no external DC power supply is connected to the socket S at the operation of the sound amplifier by means of an AC power supply, the switch is kept closed and a resistor R3 is short-circuited.
