Title: Differential apd circuit
Inventor: FUJITA TETSUYA
IPC: H03K19/086
Filed: 1994-09-29
Abstract: PURPOSE: To make the size small and to facilitate the design by selecting the same reference potential of a differential active pull-down (APD) circuit as an output reference potential in a single end APD circuit. CONSTITUTION: A constant current source 11a is connected to a base terminal of a transistor(TR) Q1a being a component of a current path selected by a 1st current switch S1a and a constant current source 11b is connected to a base terminal of a TR Q1b being a component of a current path selected by a 1st current switch S1b in the differential APD circuit. Then a reference potential of the differential APD circuit is selected to be equal to an output reference potential of a single end APD circuit. Thus, when the single end APD circuit and the differential APD circuit are used in mixture, a reference potential VREG is used in common. Thus, the configuration to supply the reference potential and number of wiring used to distribute the reference potential are reduced.

Title: Copying machine
Inventor: KATSURAGI KOJI
IPC: G03G15/20
Filed: 1986-10-01
Abstract: PURPOSE:To eliminate a shift in transfer position by lowering the feed speed of copying paper, the rotating speeds of a photosensitive drum and a fixing roller, and the moving speed of a light source or original plate in synchronous relation before or after the front end of the copying paper being sent out by a resist roller passes by the fixing roller. CONSTITUTION:A main motor begins to rotate at time A and then rotates at a constant rotating speed. The original platen 1, resist roller 9, fixing roller 13, etc., are coupled with the main motor through a clutch and when the clutch operates, they begin to rotate at constant speeds with specific timing delay. At time B, the front end of the copying paper cuts off the optical axis of a sensor 14 and then a start signal S1 is generated to lower the rotating speed of the main motor. The degree of the decrease in the rotating speed of the main motor varies curvedly so as to reduce a shock as much as possible and is so set that the front end of the copying paper is caught by the fixing roller 13 when the rotating speed of the main motor decreases most. Consequently, the position shifting of a transfer image due to the collision of the copying paper after transfer against the fixing roller is eliminated.

Title: Locking mechanism
Inventor: NAKANO NOBUYUKI
IPC: A47C1/02
Filed: 1985-10-21
Abstract: PURPOSE:To obtain a stable and strong locking mechanism by interposing a spring between two or more circular-arc-shaped stopper members, which are connected with each other in the rotating direction of a driven shaft and equipped with a circular-arc- shaped guide groove, so that the spring presses these stoppers against the inner surface of a stator, thereby assembling operating members. CONSTITUTION:Between two circular-arc-shaped stopper members 4, which are connected with each other in the rotating direction of a driven shaft 3, a spring part 5, which presses these stopper members 4 against the inner peripheral surface of a stator 2, is interposed. In addition, an operation knob 6 as an operating member, which is equipped with an engaging pin 6a that is engaged with a circular-arc-shaped guide groove 7 and which can be rotated from the outside, is provided. When this knob 6 is turned, a circular-arc-shaped stopper surface 4a, which is situated toward the turning direction of the knob, can be moved in the centripetal direction, resisting the pushing force of a spring member 5. Accordingly when the operating physical force of the operating member 6 is released, a stable locking state can be obtained by means of the spring member 5. Thus, the number of parts can be reduced, and the cost can also be lowered.

Title: E.collie strain, method for stabilized this characteristics and preparation of l-tryptophan
Inventor: HEREN KAMAKARIZU
IPC: C12P13/04
Filed: 1996-09-05
Abstract: An E.coli strain which 'over-produces' L-tryptophan, comprises, in the genome thereof, a mutant gene which encodes partially-defective tryptophanyl-tRNA synthetase (preferably the trpS378 allele) - which when present in a non-producing strain, is characterized by a temperature-dependent tryptophan auxotrophy - and has a further mutation on the chromosome thereof in at least one gene selected from mtr (especially mtr - 24 ), aroP (especially aroP579 ), tnaA (especially tnaA1 ) and tnaB . The strains may be transformed with a plasmid which carries the tryptophan operon encoding an anthranilate synthase enzyme, freed from feedback inhibition by tryptophan, and/or which possess mutations in at least one gene selected from the trpEDCBA - group (which, when present in a non-producing cell, confers tryptophan auxotrophy thereon). L-tryptophan may be prepared by the cultivation of the said strains at ca. 30 degrees C (preferably in the presence of yeast extract), limiting growth by the concentration of available phosphate (in an appropriate medium), followed by fermentation (in the absence of yeast extract) at from 33 to 37 degrees C. The fermentation is preferably effected in the absence of antibiotics.

IPC: B29C55/12
Filed: 1984-11-09
Abstract: PURPOSE:To make stable measurement with satisfactory reproducibility possible even at low elongation multiplying factor by providing a holding stand with a clip and a sliding groove provided, a long and a short link and a connecting pin to form a pantagraph mechanism. CONSTITUTION:A rectangular sample S to be tested is set at a chip C at a resetting position where clips C are spaced most narrowly. Drive spindles 2, 3, 4 and 5 are rotated by starting a motor 1 and resultantly moving tables 11, 12, 13 and 14 move at the same velocity in an arrow direction. Following this movement, a terminal point block shifts in an enlargement direction. As a result, each side of the example S is elongated to both sides of an original clip Co centering around side clip. Each clip C moves by a pantagraph mechanism consisting of two kinds of clip C, long and short, so the space between each clip C is uniformly enlarged, thus enabling uniform elongation tests.

Title: Transmission line and stub
Inventor: MORIYAMA SHINICHI
IPC: H02G1/00
Filed: 1994-09-29
Abstract: PURPOSE: To have a delay effect of high-frequency waves at the same time with radiating heat of an internal conductor easily by forming either the internal conductor or an external conductor in the spiral shape. CONSTITUTION: In a transmission line 10, an internal conductor 11 having a smaller diameter is installed at the inner diameter side and an external conductor 12 having a larger diameter is installed at the outer diameter side. The inner conductor 11 is formed in the spiral shape. The spiral may be in any shape and can be designed at pleasure. Since the internal conductor 11 is formed in the spiral shape, high-frequency waves of a TEM mode which propagate at the light velocity in a free space in the direction perpendicular to both the electric field and the magnetic field propagate along the spiral between the spiral internal conductor 11 and the external conductor 12. Therefore, an effective propagation velocity of the high-frequency waves in the axis direction becomes slower than the light velocity.  At the same time, since there is no dielectric, etc., filling a space between the internal conductor 11 and the external conductor 12, heat radiation of the internal conductor can be done efficiently even if the internal conductor 11 generates a relatively large amount of heat.
