Title: Thermal protector
Inventor: ADAMANTEIOSU ANTONASU
IPC: H01C1/028
Filed: 1988-10-03
Abstract: PURPOSE: To absorb the energy of explosion due to an abnormally high temperature, and to prevent the generation of fire due to emitted particles by forming a first layer made of an energy absorbing material and a second layer made of an elastomer material into a capsule. CONSTITUTION: A thermal protector A is formed into a capsule of a first layer 24 made of an energy absorbing material and a second layer 28 made of an elastomer material. Then, this is connected with an electric circuit through a conductor connected with metallic disks 14 and 16 provided in the layer 24. The layer 24 softens and melts beyond an operating temperature area, absorbs an energy, and absorbs gas and particles at the time of explosion in an abnormal high temperature. Also, at the time of explosion, the layer 28 expands within an elasticity limit, absorbs the energy, and prevents the particles from being emitted. Thus, firing due to the particles emitted to the outside owing to the explosion can be prevented, and the generation of fire can be prevented.

Title: Formation of semiconductor element isolation region
Inventor: KAWAMURA AKIO
IPC: H01L21/32
Filed: 1990-09-18
Abstract: PURPOSE:To easily make an active region and an isolation region fine and to largely contribute to a high integration by a method wherein the encroachment of a bird's beak on the active region of a silicon oxide film formed in the isolation region is suppressed extremely. CONSTITUTION:A shallow groove 8 is formed in a silicon substrate 1 in a self- alignment manner while a first silicon nitride film 3 and a second silicon nitride film 7 which has been left on the stepped sidewall part of an opening part 5 are used as an etching mask. When an oxidation operation is executed by a thermal oxidation method, a silicon oxide film 9 is grown in the groove 8 in which the silicon substrate 1 is revealed. Since, at the oxidation operation, oxygen is not supplied to the surface of the silicon substrate 1 covered with the first silicon nitride film 3, a silicon oxide film is not grown. Since a second silicon oxide film 6 is very thin, the supply of oxygen is small. Since it is held down by the first and second silicon nitride films 3, 7 at its upper part, the encroachment of a bird's beak is very little as compared with that in conventional selective oxidation methods.

Title: Optical disk device
Inventor: HAYASHI SHIGEO
IPC: G11B7/004
Filed: 1987-10-07
Abstract: PURPOSE:To decrease the output level of laser beam projecting an optical disk by attaining the intermittence of a light flux from a light source at the waiting time after the action of recording/reproducing information. CONSTITUTION:The output of an intermittent signal generating circuit 76 is applied to one of the input terminal of a logical gate 75, and a waiting signal W from a CPU 80 is applied to the other input terminal. When the waiting signal W is at '1', namely at the waiting time, a high frequency pulse from the intermittent signal generating circuit 76 is applied through the logical sum circuit 75 to the base terminal of a transistor (TR) 74, and the TR 74 repeats an ON/OFF action. Consequently, an information reproducing current flowing on a semiconductor laser 11 is intermittently bypassed to the TR 74, the current is intermittently applied to the semiconductor laser 11, and blinking is repeated. On the other hand, when the waiting signal W is at '0', the TR 74 is always in an OFF-condition. Thus, the output level of the laser beam can be decreased.
