Title: Lateral pnp transistor and manufacture thereof
Inventor: KURITA HIROSHI
IPC: H01L21/331
Filed: 1987-04-01
Abstract: PURPOSE:To improve a transition frequency of a transistor by forming a low concentration P-type diffused layer on a collector region and an N-type diffused layer on an emitter region, and the approaching collector and emitter diffused layers to each other by means of thermal diffusion. CONSTITUTION:A low concentration acceptor impurity is ion implanted in the degree of substantially eliminating the conductor of an N-type conductivity layer of an epitaxial layer 3 through the opening 7 of an insulating film 5 to become an emitter region. Then, doner impurity is ion implanted through an opening 8 to form an emitter region. Thereafter, diffused layers 10, 11 of collector and emitter regions are approached to each other to be formed by a heat treatment. Thus, an oblique base is formed on a base region directed from the emitter side to the collector side. Then, other base region is depleted or formed in a P-type, carrier base running time is shortened to enhance its transition frequency.

Title: Liquid level detecting device
Inventor: NAGASHIMA HIROSHI
IPC: G01F23/30
Filed: 1983-05-09
Abstract: PURPOSE:To improve vibration resistance, detecting accuracy, life and explosion proof, by the constitution, wherein a float is inclined up and down with the increase and decrease in liquid level, a liquid in a tube is moved in the separating direction from the outer end surface of a prism or in the contacting direction to the outer end surface, and light from a light emitting element is made to transmit or not to transmit to a light receiving element by the prism. CONSTITUTION:When a liquid level reaches a specified upper limit, a float 1 is inclined upward. A liquid 6 flows in the direction of a root part so as to cover the outer end surface of a prism 4. The light from a light emitting element 5a is not reflected by a reflecting surface 4m and is not inputted to a light receiving element 5b. Based on this state, reaching of the liquid level to the specified upper limit is electrically detected. When the liquid level reaches a specified lower limit, the float 1 is inclined downward, and the liquid 6 flows in the direction of a tip part and is separated from the outer surface of the prism 4. Therefore, the light from the light emitting element 5a is reflected by the reflecting surface 4m of the prism 4 and received by the light receiving element 5b. Based on this light received state, reaching of the liquid level to the specified lower limit is electrically detected.
