Filed: 1977-12-20
Abstract: PURPOSE: To adjust the strokes of a slide by simple operations by connecting an eccentric drum linked to the slide so as to adjust freely to an eccentric section in a main driving shaft.  
     CONSTITUTION: If a main shaft 1 rotates by means of a gear 6, an eccentric section 4 in a cylinder body 5 fixed to the main shaft also rotates. Then, corn rods 8 arranged around the said drum vertically move according to the amount of eccentricity (a) between the center (1a) of the main shaft and the center (7'a) of the drum, and a slide 11 also moves vertically. The adjustment of the quantity (Q) of eccentricity is carried out by loosening a nut 23, sliding an annular body 18 to the left by means of a plate 25, releasing serrations 18a, 13a, so as to position the annular body 18 and the cylindrical body 5 in a discontinue relation, slidably fitting a spanner to a hexagonal section 28, rotating a pinion 27 so as to revolve around a gear 20, and thus rotating the annular body 18 and the eccentric drum 7.

IPC: B41J11/42
Filed: 1984-07-26
Abstract: PURPOSE:To provide a serial type recording apparatus requiring no mechanism for locating the leading end of recording paper and excellent in operability, constituted by arranging a non-contact type paper detector between a pinch roller and a recording head. CONSTITUTION:For example, a paper detector 38 using a reflective type photointerruptor is arranged at a position, which is below a platen 21 and corresponds to the opening part 35a of a paper pan 35, and detects not only the start end and terminal end but also the presence and absence of recording paper 46.

When the recording paper 46 is inserted between the paper holding roller 23 and the platen 21, it is bitten into the gap therebetween by the rotation of the platen 21 and a pinch roller 36 to be sent forwardly. When the recording paper 46 is detected, a paper feed motor 22 is rotated in a predetermined amount for allowing a printing start line to come and, when the rotation of the platen 21 is finished, the carriage 29 is returned to the original position to complete setting.

Title: Fault detection system of magnetic tape device
Inventor: NAKAMURA MASAO
IPC: G06F3/06
Filed: 1977-12-21
Abstract: PURPOSE: To obtain a rational fault information processing system by equipping the output of a fault detection circuit with a method which detects that fault detection information was connected for a period more than a fixed criterion and by processing only continuous fault information over the period more than this criterion as a fault.  
     CONSTITUTION: When reset input (a) is logic [0], output (e) is [0] unconditionally. If reset input (a) changes into logic [1], output (e) of FF2 when output (c) of fault detection circuit 1 becomes logic [1] for a short period changes into logic [1] following it, but before output (g) of DFF3 is inverted, the terminal (d) changes into logic [0] and output (g) remains as it is logic [0]. Since output (c) of circuit 1 becomes [1] for a long period, output (g) at this time is inverted into logic [1]. In this way, and detection output is sent out to output terminal 4 only when a fault detection time is long. The rational fault detection can therefore be made since the transmission of a fault detection output whose continuation time is shorter than the fixed criterion is inhibited.

Title: Light polarizing directional coupler
Inventor: MIYAUCHI MITSURU
IPC: G02B27/28
Filed: 1985-07-12
Abstract: PURPOSE:To reduce the passing loss of a light signal and the mixture of other polarized components by providing a polarization plane nonreciprocal element which rotates the plane of polarization by pi/4 and a polarization maintaining optical fiber which is connected thereto and has its optical axis twisted lengthwise by pi/4. CONSTITUTION:When the magnetic field direction of a Faraday rotator 3 is changed from the optical fiber 1 to the polarization maintaining optical fiber 2 and the optical axis of this optical fiber 2 is rotated counterclockwise by pi/4 in the magnetic field direction, a light signal P having a (y)-axial polarized component which is mode incident from the optical fiber 1 is rotated by pi/4 clockwise through the Faraday rotator 3 in the traveling direction and rotated by pi/4 counterclockwise through the polarization maintaining optical fiber 2, so the rotation of the plane of polarization is compensated to maintain the plane of polarization of the (y)-axis component and the light is projected as an in-phase light signal. A light signal Q having an (x)-axial component which is made incident from the polarization maintaining optical fiber 2 is rotated by pi/4 counterclockwise through the polarization maintaining optical fiber 2 in the traveling direction and further rotated by pi/4 counterclockwise through the Faraday rotator 3, so the rotations of the plane of polarization are added and the light signal Q is therefore rotated by pi/2, so that the light signal is converted into a light signal in phase with the (y)-axial component.
