IPC: G09G5/12
Filed: 1989-02-07
Abstract: PURPOSE:To save electric power by stopping the generation of a dot clock signal in a period wherein a dot clock signal needs to be oscillated, i.e. a vertical blanking period. CONSTITUTION:This display control circuit is equipped with an LC oscillator 3 which generates the dot clock signal DOTCK used to display characters and a display stopping circuit 20 which outputs an oscillation stop signal STOP to the LC oscillator 3. The display stopping circuit 20 inputs two signals, i.e. horizontal synchronizing signal HSYN and vertical display signal VDISP and outputs the display stop signal STOP according to the output of a NAND circuit 21 which NANDs those input signals. The output of the dot clock signal DOTCK is therefore stopped in the vertical blanking period. Consequently, the power consumption is reduced.

Title: Washing method of substrate
Inventor: SOGOU KOUHEI
IPC: H01L21/306
Filed: 1984-02-20
Abstract: PURPOSE:To wash a substrate efficiently at low cost by using a conventional sheet type automatic treater by each discharging a substance showing an exothermic reaction through mixing with sulfuric acid and sulfuric acid to the surface to be washed of the substrate from independent supply piping systems. CONSTITUTION:A mixing substance 1 is fed to the surface to be washed 6 of a substrate to be washed 5 from a nozzle 4 through a supply piping 3 by a feeder 2 for the substance 1. On the other hand, sulfuric acid 7 is fed to the surface to be washed 6 of the substrate to be washed from a nozzle 10 through a supply piping 9 by a feeder 8 for sulfuric acid. Consequently, the mixing substance 1 and sulfuric acid 7 are mixed on the surface to be washed 6 of the substrate 5, and an exothermic reaction is generated. When hydrogen per oxide solution is used as the mixing substance 1 at that time, nascent oxygen is also generated by the decomposition of hydrogen peroxide solution. The surface to be washed 6 is washed by the acceleration of an oxidation reaction by oxygen, a dehydration reaction by sulfuric acid 7 and these reactions by said exothermic heat. Washing action is extremely efficient because the mixing substance 1 and sulfuric acid 7 are mixed on the surface to be washed 6 requiring washing at that time.

Filed: 1982-02-22
Abstract: PURPOSE:To provide the titled turbine having a self-starting and improve operating efficiency in a high-speed range, by constituting a rotor such that a plurality of flexible blades are attached transversely to a rotor shaft and the rotor can be rotated in any given direction by air stream flowing to axial direction. CONSTITUTION:A plurality of flexible blades 35 is attached to a rotor shaft 2 transversely to its axial direction. The flexible blades 35 are formed by a leading edge beam 31 of cylindrical or similar shape, a boom 32 with its cross-section shaped as a symmetrical blade at a portion attached to a top end of blade, a slender line-shaped trailing edge 33 arranged tranversely to an axial direction of the rotor shaft 2 and horizontally to the leading edge beam 31, and a flexible blade surface 34 streched between the leading edge beam 31 and the trailing edge 33 and the like. The flexible blade 35 is acted thereon by a combined speed 10 of a flow velocity 6' of the air 6 and a peripheral velocity, but flexibility of the blade surface 34 deforms the blade into a shape that provides less resistance. In consequence, the combined velocity 10 serves to increase a dynamic lift 11 and instead reduces the resistance 41. As a result, components of the rotating direction are incrased, whereas the turbine receives greater torques.
