Title: External magnetic field impressing device
Inventor: TAKAHASHI TORU
IPC: G11B11/10
Filed: 1990-06-04
Abstract: PURPOSE:To suppress the rise of temperature in a magnetic circuit, and to prevent a fault accompanying the rise of the temperature at the time of recording or reproducing information in a magneto-optical disk device by constituting an electrical insulating member surrounding the outer periphery of a winding with a heat radiating member, and besides, providing a heat transferring member between a magnetic pole piece and a magnetic plate. CONSTITUTION:An upper side and a lower side heat radiating members 4a and 4b attached with adhesive are piled up at the upper and the lower sides of the winding 3, and assembled around the magnetic pole piece 1 fitted with the heat radiating member 4a. The heat transferring member 5 of aluminum alloy is interposed between the heat radiating member 4b and the upper edge part of the magnetic plate 2. When a current is made flow in the winding 3, Joule heat is generated in the winding 3, and its temperature is raised. But the heat is transferred to a magnetic pole piece or the magnetic plate through the heat radiating members 4 and the heat transmitting member 5, and the rise of the temperature can be suppressed within an allowable limit.

Title: Transistor
Inventor: YOKOZAWA MAMI
IPC: H01L29/73
Filed: 1979-11-07
Abstract: PURPOSE:To equalize a current flowing from a base area into an emitter area and to reduce a switching time by a method wherein a shape of an emitter diffusion area formed in a base area is made shallow directly under an emitter metal race way. CONSTITUTION:After a base diffusion area 2 is formed on a silicon substrate 1, a thin oxide silicon film is formed in a central part of a window for forming an emitter diffusion area. And then, an emitter diffusion is performed from this window to form an emitter diffusion area 3 having an emitter diffusion central part 3A wherein a diffusion length is small. An impurity concentration in the emitter area 3 is the highest at its superficial layer and it lowers gradually toward the diffusion front, as a result, when an emitter area under the connection part of a metal thin race way 7 is formed shallow, a current flows much at this part 3A, and a current at the bottom part of an emitter area increases to be equalized. On this account, a switching characteristics is improved, thus, safety operaion area being expanded.
