Title: Preparation of anhydrous quartz glass tube
Inventor: FUNAKI MINORU
IPC: C03B37/012
Filed: 1985-06-13
Abstract: PURPOSE:To prepare the titled tube without causing generation of crack by drying and calcination for a short time after filling dispersion of binder soln. of fine quartz particles in a liquid permeable cylindrical vessel 1, revolving the vessel at high speed by holding the center line of the axis of the vessel horizontally, and calcining fine quartz particles and a small amt. of binder deposited to the inside wall after drying with hot air. CONSTITUTION:Liquid dispersion contg. fine quartz particles dispersed in binder soln. is filled in a cylindrical vessel 1 having permeability. The center line of the axis of the vessel 1 is held horizontally and revolved at high speed causingg deposition of the fine quartz particles in the soln. together with the binder soln. to the internal peripheral surface of the cylindrical vessel 1, and excess binder soln. is allowed to permeate the cylindrical vessel 1 and discharged to form fine quartz particle layer 10. Then, a heater 5 and a blower 9 are actuated while revolving the cylindrical vessel 2 to pass hot air. Thus, the binder soln. in the fine quartz particle layer 10 is transformed to gel and a porous tube comprising fine quartz particles is formed. The porous tube is taken out by opening a cover 4, which is calcined by the usual process to obtain thus an anhydrous quartz glass tube.

Abstract: PURPOSE:To realize a 10-bit sequential comparison type analog-digital converter (ADC) by using 128 unit capacitors, by adding a resistance voltage divider, a switch array and a decoding circuit to the ADC having a sampling and a holding function. CONSTITUTION:As a synchronizing signal is applied to a terminal 124, switches 101-202 are as shown in the figure and when an analog signal is applied to a terminal 121, capacitors 103-110 are charged up to prescribed potentials.

When pulsator is rotated, water flows into the chamber 2 through overflow filter 8 provided upwardly of chamber 2 and again flows out of the chamber 2 through  water strainer 7 provided downwardly of the chamber 2. Thus, circulation of water  flow is produced. Yarns carried with this circulated water flow are collected at the  back of strainer 7. Water leakage of valve 10 due to loading of yarns can be prevented by use of weight 22 serving to urge hollow pipe 11 downward. Further, ribs  are formed on both sides of the hollow pipe 11, so that pipe 11 may be guided  along the ribs when it is moved vertically, whereby it is made unnecessary to provide any special guide in use of partition plate.

Abstract: PURPOSE:To reduce the transmission time as to a part not requiring the transmission in an input document by detecting a specific mark on an input pattern and filling the picture information of the scanning line in white level. CONSTITUTION:A mark detection circuit 4 discriminates whether or not a mark 13 exists at the scanning position during processing at present at a mark detection area 12 decided in the input pattern 10 and informs the result to a control circuit 8. The control circuit 8 informed of the detection of a mark from the mark detection circuit 4 gives a command of outputting a white level by one scanning line to a buffer memory 3. Thus, the scanning line of the part on the input pattern 10 drawn with the mark 13 is all sent as white level information and in the case of the input pattern 10, the information is rewritten into the picture information of a transmission pattern 11 and sent. Thus, the code information length to be sent is reduced.
