Title: Method and device for manufacturing solid matter product manufactured by thermal decomposition and its use
Inventor: SCHILD ANDREAS
IPC: C01B33/18
Filed: 1999-11-24
Abstract: PROBLEM TO BE SOLVED: To make obtainable a distribution as narrow as possible of particle characteristics such as primary particle grain size, aggregate grain size, the number of primary particles per aggregate, specific surface area, and the like by introducing a reaction mixture into a reaction chamber through at least one molding with a channel penetrating in the flow direction. SOLUTION: A starting gas mixture comprising air, hydrogen, a volatile metal and a metalloid compound, e.g. silicon tetrachloride is introduced into a supply pipe 6 similar to a wind tunnel from a mixing chamber, and it is made to communicate with a molding 7, around which an annular suction inlets for air and hydrogen are provided. The molding 7 is a member of a burner designed as a sealed burner. That is, the air introduced from the side of the molding 7 is not sucked but is metered and introduced by a metering device. In order to create a uniform flow condition, a burner flame is introduced into a pipe 8, and then a silicon dioxide generated thereafter can be guided further into a reaction chamber 9.

Title: Cassette loading device
Inventor: OHASHI KENJI
IPC: G11B15/675
Filed: 1995-12-21
Abstract: PROBLEM TO BE SOLVED: To reduce the cost of a driving device of a slider assembly for mounting a cassette and transporting it to the loading position and also to reduce the cassette inserting force. SOLUTION: When the cassette 11 is pushed in the direction of arrow C while keeping pin parts 2a of a holder 2 of the slider assembly so as slidably inserted to a groove part 6a long in the radial direction of a drive gear 6, the area corresponding to a backlash G due to the lack of tooth of a driving rack 8 is inserted without special force. Further, a backlash H due to the lack of tooth is provided also on the driving side of the driving rack 8, and by detecting the movement a little before the backlash H is moved, a motor is driven and the cassette is transported by the rotation of a driving gear 10.  At the time of turning back, since the operation opposite to that at the time of insertion is made since the rack and gear are engaged, the turn-back is executed by an energizing spring 12 having the spring force only for turning back the initial backlash, and therefore, a conventionally used restoring rack and a restoring spring with strong spring force are not required.
