Title: Production of carbide
Inventor: AMINO TOSHIKAZU
IPC: C01B31/30
Filed: 1986-12-26
Abstract: PURPOSE:To contrive to extremely improve heat efficiency in reacting a metallic oxide with carbon in a solid phase, by dropping raw materials through a preheating zone of a reactor, fluidizing the raw materials with a gas containing a reducing reaction gas in a heating zone to give a carbide and cooling the carbide in a cooling zone. CONSTITUTION:Raw materials consisting of metallic oxide powder and a carbonaceous substance are fed from the top of a reactor having a preheating zone, a heating zone and a cooling zone. As the raw materials are dropped in the preheating zone under gravitation, reach the heating zone. The raw materials are heated in the heating zone while being fluidized with a fluidizing gas containing at least a reducing reaction gas to form a carbide. Then a reaction product containing the carbide is dropped to the cooling zone, cooled in a nonoxidizing atmosphere and the reaction product is discharged from the bottom of the reactor. By this method, various carbides can be produced in high yield, stably and continuously and operation can be carried out under an extremely effective condition.

Title: Optical disk device
Inventor: SASAKI TSUKASA
IPC: G11B19/28
Filed: 1991-10-31
Abstract: PURPOSE:To reduce track count errors without a special device by installing a means which preliminarily counts and stores the number of tracks from the point of time when the absolute time of a set disk is 0 up to a specified time. CONSTITUTION:When a linear velocity is assumed to be 1.3m/s, the tracks whose absolute is 30min, are jumped at first. The absolute time recorded at the jump destination is read. When the absolute time is not 30min, a further attempt to jump is made. It is possible to reach a track whose target absolute time is 30min by repeating this operation. The number of tracks which starts at a 0min-absolute time and reaches the target value is counted and stored so as to determine a corrected value. In this case, absolute time of a disk is read from data generated at a signal processing section 23 in a CPU while a count value obtained from a tracking counter 25 is read at the same time, thereby operating the corrected value based on the data and operating or storing the number of racks to be jumped.

Title: Preparation of bipolar transistor
Inventor: REN HEIRETSU
IPC: H01L29/73
Filed: 1994-12-19
Abstract: PURPOSE: To enhance integration of an element while simplifying the process by forming the base at an etched part of an insulation film through the use of an SEG step, forming a side wall film defining an emitter region on the side face of a nitride film, forming a conductive emitter layer in the emitter region thus defined and then interconnecting the electrodes. CONSTITUTION: Integration of element is enhanced through the use of a step for making a shallow trench and the number of trenches is decreased by thermally oxidizing the collector region 23 on the outside of an active region such that the collector region 23 has a depth similar to that of the shallow trench. Unnecessary regions are then removed from an isolation film and an insulation film defining the active region thus reducing the size of element and the parasitic capacitance between the subcollector and the board. Since the thickness of insulation film can be adjusted arbitrarily to the order of the thickness of shallow trench, parasitic capacitance of metal interconnection can be decreased.  Furthermore, the process is simplified by eliminating the trench isolation step and the SEG step for growing interconnect polisilicon arsenide while self-aligning the emitter, base and collector.
