IPC: G11B7/085
Filed: 1994-12-26
Abstract: PURPOSE: To carry out normal focus servo accurately at high speed by detecting each specified region of a focus error signal and a focus servo signal and starting focus servo. CONSTITUTION: A focus error signal FE and a focus servo driving signal FSS are applied to a focus zero detecting section 12 and a diving-signal zero detecting section 17 respectively.

All the conversion coefficient F(u, 8-v) is allotted with 5 bits and the sum of F(u, 8-v) and (8-u, v) in bit length takes a value of 10 bits. In the coupling, which part among the 10 bits is allotted with which signal is determined according to charbick algorithm. Thus, determination by a decoder of video keys used in the transposition can be made difficult.

Title: Radiation structure for case
Inventor: EMORI TOSHIHIKO
IPC: H05K7/20
Filed: 1993-12-22
Abstract: PURPOSE:To prevent dust and dirt from entering by radiating heat with thermal shape memory alloy of a top plate deforming reacting with a temperature rise inside a case to form a radiation hole. CONSTITUTION:A top plate 2 is equipped with thermal shape memory alloy 10 which deforms with high temperature and thermal shape memory alloy 10 which deforms at normal temperature. When a heat source 1 generates high temperature, the alloy 10 deforms reacting with a temperature rise inside a case, forming a radiation hole on the top plate 2 to permit heat inside the case to be radiated. When power supply to a device ceases, the alloy 11 deforms reacting with a temperature drop inside the case, restoring the top plate 2 to an original state. Thus entrance of dust and dirt can be prevented.

IPC: F23R3/00
Filed: 1990-11-27
Abstract: PURPOSE:To always improve combustion efficiency and also allow smooth operation all the time by fixing one end to the wall face of a combustion chamber, and forming a circular flow generation part by means of a curved stepping plate extended in a condition that other end thereof is laid along the flow of high temperature gas. CONSTITUTION:A mixing combustor 2 is provided with a combustion chamber 3 which generates high temperature gas flow by mixing atomized main fuel in the flame flow consisting of combustion gas including excessive fuel followed by flame and compressed air. One end 10a of the mixing combustor 2 is fixed to the wall face 3a of a combustion chamber, and a circular flow generation part is formed by means of a curved stepping plate extended in a condition that the other end 10b is laid along the flow of high temperature gas downstream from the one end 10a and on the center side of the combustion chamber 3. Consequently, since increase in high temperature gas passing area is reduced downstream from the circular flow generation part, mixing of flame flow with main fuel is performed uniformly, and flame propagation is effectively performed, and total pressure loss is reduced so as to improve a combustion efficiency. Since the resonance in the direction of the high temperature gas flow can be suppressed, always smooth operation is allowed.
