Title: Quartz boat and method of producing compound semiconductor single crystal by boat method using the same
Inventor: SEKI MINORU
IPC: C30B11/00
Filed: 1999-11-22
Abstract: PROBLEM TO BE SOLVED: To provide a quartz boat with which a compound semiconductor single crystal almost free from polycrystal is obtained and a method of producing the single crystal by a boat method. SOLUTION: The outer surface positioned at the shoulder part 10a of a quartz boat 10 accommodating a raw material 3 and a seed crystal 4 is made transparent. Thereby, the radiation heat from a high temperature heater 6 reaches the melt of the raw material 3 at the shoulder part 10a without being scattered, although the radiation heat is scattered at the opaque part, and the effect of partial heating can be obtained. Accordingly, the temperature at a bottom part 10aa of the shoulder part 10a can be raised, solid-liquid interface is prevented from becoming a recessed form, and a single crystal almost free from polycrystal can be obtained.

Title: Digital television video signal processor
Inventor: ONOZATO MASASHI
IPC: H04N11/04
Filed: 1987-12-25
Abstract: PURPOSE:To execute an exact blanking processing by providing a circuit to switch a Y signal to a constant value, which is smaller than a pedestal level, in correspondence to a signal to show a blanking period and integrating the value of data, which show the blanking period, into picture data. CONSTITUTION:A video input signal 1 is converted to the PCM data of 8 bits, for example, by an A/D 2. In a blanking period generator 11, a blanking(BLK) control signal 14 to be synchronized to the video input and to express the blanking period is obtained from vertical phase information 12 and a clock 13. A selector 7 is operated by the BLK control signal 14 and the BLK data from a BLK data generator 8 are padded into the Y signal after being black- clipped. Here, the BLK data are obtained as a 3B (16-ary). Since there is no value of <3C for the Y signal by a black clip 6, the period of the value 3B can be easily and securely detected with the blanking period.

Title: Paper feeder
Inventor: MURASAWA TOYOAKI
IPC: B65H3/68
Filed: 1988-12-29
Abstract: PURPOSE:To make stable paper feeding performable at all times by projecting a paper guide member farther from a friction member contacting with a paper feed roller under pressure. CONSTITUTION:When a tip of paper is fed to a pressure-contact point between a paper feed roller 3 and a friction member 6, this paper is guide by a guide member 7 projected farther from this friction member 6. Consequently, such a possibility that the paper tip might be folded as hitched on the friction member 6 is brought to notching. Next, even if the friction member 6 is worn out by friction with the paper after carrying out a large quantity of copies, the friction member 6 supported free of rotation is slightly rotated and merely refixed, whereby double-feed preventing performance is kept intact. In consequence, stable paper feeding is always performable.
