Abstract: PROBLEM TO BE SOLVED: To obtain an adequate process for sintering a large hollow cylinder of silicon dioxide soot and a retaining apparatus of the hollow cylinder which is easy to attach and disassemble and assure safe and highly reliable handling.  
     SOLUTION: A hollow cylinder (5) is held in a vertical orientation and sent continuously through a heating zone for sintering.

In a second phase the cylinder hangs from a rataining ring while its lower end (10) is sintered. A vertical retaining rod (1) is fixed to the base (3) on which its *1 lower end is supported, and extends through the hollow cylinder. The retaining ring is fixed inside the upper end of the hollow cylinder. During the first phase, the upper end (12) vitrifies and contracts so that the retaining ring engages the jacketed pipe (2). Longitudinal contraction causes the lower end to lift off the based so that the cylinder is suspended.

Abstract: PURPOSE:To prevent the in-pile structure from being damaged due to flow vibration by lowering a position of a reactor core shroud support leg from the lower end of a control rod guide tube, and expanding its breadth by that portion. CONSTITUTION:First of all, as for reactor water of a downcomer part 12 between a pressure vessel 4 and a wall of a reactor core shroud 5, a suction flow 9 is pressurized by an internal pump 6, becomes a discharge flow 10 from an opening part of a reactor core shroud support leg 5a and flows into a reactor.

Filed: 1986-10-07
Abstract: PURPOSE:To eliminate the need for a correcting circuit and to reduce the cost of equipment by applying a bias voltage which is different according to the array position of a photosensor to a light shield layer. CONSTITUTION:An original P is irradiated with light L which is incident through the incidence window 19 of a transparent substrate 11 and its reflected light is received by a photosensor part 108 to read out a read signal through electrode wiring. Namely, when the reflected light L is incident on the surface of a semiconductor layer 14 through a photodetection part 118 while a high-potential driving voltage based upon the potential of a main electrode 116 is applied to a main electrode 117, carriers increase and then the resistance decreases, so that the variation is read as image information. At this time, the bias voltage which is different according to the array position of the photosensor is applied to the light shield layer 112 and the distribution of the sensor output is smoothed when the image is read, thereby eliminating the need for the correcting circuit.

Title: Line switching device for facsimile
Inventor: SHIINA KATSUMI
IPC: H04N1/00
Filed: 1990-09-10
Abstract: PURPOSE:To reduce the total number of lines, and to improve the using efficiency of the line by switching and connecting plural signal processing parts to the optional one of NCU parts or ISDN I/F parts connected to a PSTN line or an ISDN line. CONSTITUTION:When the response request of a G3 standard arises, a control part 2 sends a control signal to a switching part 10, and connects the NCU or the ISDN I/F having received call incoming to a non-operating G3 processing part, and executes call receiving operation. On the other hand, when the call incoming of the response request of a G4 standard arrives through the ISDN line, the receiving operation is executed by a G4 processing part connected directly to the ISDN I/F having received the call incoming. As mentioned above, since the operation of transmission and reception can be performed without any trouble if the number of the lines is made previously more or less the maximum number of the lines a device is estimated to transmit and receive at a time, the number of the lines can be greatly reduced compared with the total sum of a handset 11, the G3 processing parts 12a1 to 12an, and the G4 processing parts 13a1 to 13am.
