Title: Paper feed controlling system
Inventor: MITSUMOTO MASAHIKO
IPC: B41J11/42
Filed: 1986-06-19
Abstract: PURPOSE:To minimize the scattering of a printing position and enable high-quality printing, by controlling the paper-feeding velocity in the period from the moment a paper is in the vicinity of a paper-detecting means to the detection of the paper to be lower than the paper- feeding velocity, before and after the period. CONSTITUTION:In the steps from the moment a paper is in the vicinity of a sensor to the moment the positioning of the leading end of the paper is detected by the sensor, when a comparator 20 detects the coincidence of the number of steps sent from a moving quantity data register 11a with a count from a timer part 60, a coincidence signal causes a controlling part 1 to change over a switch 15 to the side of a stop data register 12c and change over a switch 14 to the side of a low-speed rotation data register 12b. Then, the controlling part 1 accelerates the rotation of a line-feeding motor 4 to a speed specified by the register 12b (a speed sufficiently lower than the speed specified by a high-speed rotation data register 12a), and it again stops the line-feeding motor 4. Under this condition, the controlling part 1 reads a signal 1 from the sensor 32 through a level-changing circuit 7, and when the positioning of the leading end of the paper is not detected by the sensor 32, the controlling part 1 accelerates the rotation of the motor 4 to the speed specified by the register 12b. By this, secure detection by the sensor of the position at which the leading end of the paper is positioned can be achieved, the scattering of a printing position can be reduced, and high- quality printing can be performed.

Title: Screw for thermoplastic resin
Inventor: NOZAWA KENJI
IPC: B29C48/76
Filed: 1984-07-11
Abstract: PURPOSE:To contrive to improve the surface replacement effect and to prevent venting-up from occurring by a structure wherein 2-6 flutes, each of which consists of two threads respectively having specified angles in the axial direction and one group of each of which is a flute open on upstream side and closed on downstream side and the other group of each of which is a flute open on downstream side and closed on upstream side, are provided in such a manner that said two groups of flutes are arranged alternately. CONSTITUTION:Flutes 14, each of which is open on upstream side and closed on downstream side, and flutes 15, each of which is open on downstream side and closed on upstream side, are alternately arranged with no communication between the flutes on the outer peripheral surface of a screw element 13 provided just before the vent port 12 of a screw main body 11. Resin entered the flute 14 from the main body 11 side passes over a thread 16 through a small gap (b) into the flute 15. The angle alpha between the thread 16 and the axis of the main body is set at 25-45 deg., because resin is sent in the flute 14 at all times. Further, because the depth of the flute 15 is made larger than that of the flute 14 or the volume in the flute 15 is larger than that in the flute 14, the resin entered the flute 15 is released from its compressed state, resulting in increasing volumetrically and consequently improving the surface replacement effect. The angle beta between the thread 17 and the axis of the main body is set at 50-75 deg., because the flute 15 itself must have resin conveying capacity. The number of flute is made to be 2-6.

Filed: 1985-07-01
Abstract: PURPOSE:To make the device small-sized and sufficiently durable by providing the aspheric surface convex lens, the light source device, the light shutter means, the driving device, etc. CONSTITUTION:A laser beam is emitted from a single color light source 30 in the right-angled direction to the shifting direction of a movable stand 12, converged to a focusing point 34 by a collecting lens 32, and thereafter, the beam is diffused again and irradiated to the front surface of an optical deflecting element 15. At such a time, the same action as the action that a convex lens part 18f is shifted in the direction right-angled to the optical axis up to the position of a convex lens part 18g is executed, and the laser beam is deflected. Especially, since the focusing point 34 is located between the focus F and a point F2 equivalent to two times of the focus position in the optical axis direction of the aspheric surface convex lens, the interval between focusing points Sf and Sg is larger than the dislocation quantity of partial convex lens parts 18f and 18g and the shifting distance of the focusing point is largely amplified. In such a way, the device can be small-sized and the durability can be improved.
