IPC: F27D21/02
Filed: 1995-08-01
Abstract: PROBLEM TO BE SOLVED: To obtain an improved single crystal production apparatus effective for preventing the clouding of an inspection window caused by the deposition of a component having high vapor pressure without causing the disturbance of the thermal balance in the furnace, etc. SOLUTION: An inspection window 3 is provided with a protection cover 31 surrounding a quartz rod 30 for inspection. The protection cover 31 is composed of a cover main body 31a surrounding the side face 30b of the rod protruding into the furnace 2 excluding the end face 30a of the quartz rod 30 in the furnace and a flange part 31b formed on the upper edge of the cover main body 31a. The flange part 31b is bonded and integrated to a reflector 40 of a water-cooled reflector part 4 in a high-pressure vessel 2 and the cover main body 31a is cooled by the flange. When the gas component in the high-pressure vessel 2 is brought into contact with the cover main body 31a during the growth of crystal, the gas component is cooled, solidified and deposited on the surface of the cover main body 31a.  Accordingly, the solidification and deposition of the gas component on the end face 30a of the quartz rod in the furnace can be prevented to prevent the clouding of the end face of the rod.

Title: Image reader
Inventor: TAKAHASHI TADASHI
IPC: H04N1/19
Filed: 1995-08-02
Abstract: PROBLEM TO BE SOLVED: To provide an image reader which can fast read a source document by reading out the right and left parts of the source document at a time and independently of each other and acquiring a series of signals through the image processing of the source document. SOLUTION: A source document is scanned by two mirror units having a 2:1 scanning ratio and read by a color CCD sensor 1100. A linear photodiode array is divided into the right and left parts, and the outputs inverse to each other are sent to an image processor. The image processor delays the reset pulses RS1 and RS2 generated at a timing generation part 3009 by the delay elements 6001 and 6002 in the timing accordant with the right and left transfer paths respectively and supplies these delayed reset pulses to a reset part to combine the right and left pixel signals into a series of signals in terms of time series after adjusting the right and left timing independently of each other. In such a signal processing way, the source document can be fast read together with the fast scanning that is carried out by the image reader body.

When the difference TDIF1 is within the defined valued when it is discriminated, the present address TPRS which is read is judged to be correct, and it is submitted for an operation for access action. When it is discriminated to be beyond the defined value, the difference between the address TOBJ of the objective position which a host computer 33 has specified and the present address TPRS is calculated through a host computer interface 32. When the difference TDIF2 is within the defined value, the present address TPRS is judged to be correct. Thus, access action is attained at high speed.
