Title: Data signal transfer system
Inventor: YOSHIMURA GENICHI
IPC: G06F15/177
Filed: 1979-03-24
Abstract: PURPOSE: To secure the transfer of data signals by invalidating the transmission of data signals when a receivable signal can not be confirmed through confirming operation.  
     CONSTITUTION: On the basis of a received data signal, reception part microprocessor RMPU performs fixed operation and when the data signal is receivable, a receivable signal is sent out. Transmission part microprocessor SMPU, on the other hand, detects the received signal from the reception part and then outputs a data output indication signal to the reception part to send fixed data out. After the end of the transmission of the data signal, processor SMPU is allowed to make sure of whether the receivable signal is sent out from the reception part within a certain time. When the receivable signal is not confirmed through the confirming operation, the transmission of the data signal is invalidated. Consequently, the secure transfer of the data signal comes into effect without increasing signal lines in number.

IPC: B23B5/36
Filed: 1981-03-12
Abstract: PURPOSE:To avoid leaving any uncut portion on the axis of rotation of a workpiece, by providing a servomotor on a main rotary shaft on which a tool is held, to specifically control the radius of rotation of the tool depending on the angle of its rotation to revolve the tool along an ellipse. CONSTITUTION:When a paraboloid of revolution is expressed as z=1/4alpha(x<2>+y<2>) where alpha denotes the focal distance, the angle phi of rotation of a tool 25 and the radius gamma of its rotation are controlled into a relationship defined by a formulaI. The axis of a main rotary shaft 24 is inclined at an angle of theta to that of rotation of a workpiece W. Trains of pulses are produced for simultaneous operation along two axes by a numerical controller 45 on the basis of electronic computation according to the formulaI. On train of pulses are applied to a servomotor 43 to rotate the main shaft 24 for the tool 25. The other train of pulses are applied to another servomotor 28 to move the tool 25 in the radial direction. The cutting edge of the tool 25 is thus revolved along an ellipse. The workpiece W is slowly rotated. As a result, the desired paraboloid of revolution is generated.

Abstract: PURPOSE:To accelerate the process for a recording material and to improve processing ability by carrying a longwise recording paper from the vertical direction. CONSTITUTION:A photosensitive body for image forming is incorporated in a printer main body 1. An image is formed and developed on the surface of the photosensitive body, and the developed image on the photosensitive body is transferred in a transfer area 6 on the recording paper 4 to perform printing. In this case, to vertically feed the recording paper 4, a cassette 2 housing the recording paper 4 is set to the printer main body 1 so that the longer side 4a, that is, the major direction of the recording paper 4 is specified as a carrying start point in the direction of an arrow 5 with respect to the transfer area 6 of the printer main body 1. In other words, the direction of the long side 4a of the recording paper 4 in the cassette 2 is set along the width direction 6a of the transfer area 6. Thus, by specifying its longer side 4a as the carrying start point, the recording paper is fed toward a shorter side in the direction of 4b. Therefore, the carrying time of the recording paper 4 is shortened, and operational efficiency can be improved.
