IPC: G03G15/20
Filed: 1983-02-09
Abstract: PURPOSE:To prevent even long-sized copying paper from zigzagging by providing a pressure roll so that its axial line crosses the axial lines of a couple of fixing rolls which are parallel to each other and have different diameters only at a fine angle, pressing the pressure roll by a pressure applying means, and adding a pressure releasing mechanism. CONSTITUTION:The fixing rolls 1a and 1b are installed in parallel to each other, so when copying paper 6 is passed between the fixing rolls 1a and 1b, the paper insertion direction is coincident with the paper ejection direction to prevent the zigzagging of the running paper to some extent. When the long-sized copying paper is used, an eccentric cam 16 is rotated by 180 deg. by rotating a support shaft 15 by 180 deg. and then levers 11b and 11'b are pressed up. Consequently, one-side terminals 11a and 11'a of the levers 11 and 11' are moved down and no pressure operate between the fixing rolls 1a and 1b, and fixing roll 1b and pressure roll 2. Therefore, the track of the copying paper 5 running between the fixing rolls 1a and 1b is corrected.

IPC: H03K3/02
Filed: 1980-02-20
Abstract: PURPOSE:To eliminate the limitation of the working frequency, by constituting a retriggerable multivibrator with two flip-flops. CONSTITUTION:The time constants C1R1 and C2R2 of the two integral networks 7 and 8 are selected as C1R1>>C2R2. When a pulse signal having the period T0 shorter enough than the time constant C1R1 is applied to the clock terminal of each flip- flop, the flip-flop 1 is not set with its Q output signal 4 kept at a low level. On the other hand, if the period T0 of the input signal is larger enough than the constant C1R1, the time working state decided by 0.7C1R1 is kept to give a restoration. When the input signal pulses are supplied consecutively, the working time is started at the time point when the final pulse of the input signals that continue in the time interval less than 0.7C1R1.

IPC: H01S3/06
Filed: 1993-02-08
Abstract: PURPOSE:To provide an optical fiber for optical direct amplification in a specific mum band and an optical fiber amplifier using it. CONSTITUTION:Amplifying optical fiber 7 composed of a core formed of optical glass that contains neodymium (Nd<3+>) and thulium (Tm<3+>) and a clad which surrounds the core and has lower diffraction factor than the core is used.

Abstract: PROBLEM TO BE SOLVED: To equalize the concentration of a feed solution in each part in a pan and further to prevent the nonuniform wear of a scraper by providing an agitation member rotatably supported around a horizontal axis for agitating a solution in a receiving pan. SOLUTION: First, a feed solution is stored in a receiving pan 20 and a drum 10 is heated and is rotated in the direction as shown by the arrow P. Then, a motor is driven to rotate a major shaft 32. In this way, rotation shafts 37, 38 rotate links 51, 52 respectively to rotate the heads thereof on circular loci, and links 53, 54 are oscillated in the directions as shown by the broken lines. As a result, oscillation plates 60, 61 are oscillated within a fixed angular range around a drum shaft 13 as a horizontal axis, and agitation blades 62 at the head parts thereof agitate the feed solution in the receiving pan 20. Therefore, even when the drum 10 is heated to increase the concentration of the feed solution, nonuniform deposition of solid matter in the receiving pan 20 is prevented, and consequently the occurrence of nonuniform wear and vibration of a scraper 40 itself is prevented.

The insulating film 11' is formed on the above base layer and only the insulating film 11' located at the upper part of the exposed base layer 4 is removed by dry-etching and then this device allows a semiconductor layer 5 having the same conductivity type as that of the base to brow at the upper part of the exposed base layer 4 with an epitaxial growth technique, thereby holding a space between it layer 5 and the collector as it is. Thus, a structure having exceedingly short and low base-length and small junction capacitance is obtained by maintaining the ease of taking out the base electrode as it is.
