Title: Encoder
Inventor: NAKAYAMA HIROSHI
IPC: G01D5/26
Filed: 1992-02-28
Abstract: PURPOSE:To enable an encoder to detect not only the abnormality of an optical system, but also such a small abnormality as accuracy deterioration by calculating acceleration from three continuous angle data and detecting the abnormality from the acceleration data. CONSTITUTION:A computing element 10 first computes the differential (sintheta) in digital value of a first subtracting means between the turning-on time and turning-off time of a light source and the differential (costheta) in digital value of a second subtracting means between the turning-on time and turning-off time of the light source. Then the element 10 computes an angle by computing the phase of sine wave-like illuminance distribution based on the two differential data. Since the differential among three continuous angle data can be expressed by the product of the squares of acceleration alpha and sampling interval DELTAT when the three continuous angle data and sampling interval are respectively represented by X1, X2, and X3 and DELTAT, abnormality can be detected from acceleration data by computing the acceleration from a prescribed expression.

IPC: B41K3/48
Filed: 1980-04-02
Abstract: PURPOSE: To accelerate a tape feed speed and to improve a pitch correction precision, by a method wherein driving of two rollers is switched by means of an electromagnetic clutch, and this enables a feed of a pattern-printed tape to be changed in two stage.  
     CONSTITUTION: In case an electromagnetic clutch 4 is set into an OFF condition, a drive shaft 61 drives a delay roller 12 through gears 71, 73, a one-way clutch 8, and a shaft 52. A tape 9 is fed out through the nip formed between a free roller 2 and the roller 12, and a roller 11 serves as a driven roller thereon. With the electromagnetic clutch 4 brought into an ON condition, the roller 1 is driven serving as the drive roller. The speed of the roller 11 is faster, and as a result, the tape 9 is increased in a feed rate. This causes switching in two-stage of a tape feed speed, correction of a feed distance, and acceleration of a tape feed speed, and permits the improvement of a pitch correction precision.

Abstract: PURPOSE:To reduce irregular burning and irregular heating at a lower surface of a heated material by a method wherein a concave part is formed at a rotating shaft of a turn table, this rotating shaft is reinforced and several punched holes are also formed in the concave part. CONSTITUTION:A central part of a turn table 10 is drawn to show a projection at a bottom wall 5 of a heating chamber 3 and then an upper concave part 14 is formed. Inclined outer circumferential wall 14a of the concave part 14 and a flat mounting surface 10a of the turn table 10 are formed with several punched holes 15. A turn table part 10b passing just over a lower electric heater 9 may form punched holes 15 more roughly than that of other portions during a rotation of the turn table 10 and a rate of opening of the hole per unit area through the punched holes 15 is set low. In this way, if the heated material 2 is mounted near the central part of the mounting surface of the turn table 10, the infrared direct ray from the lower electric heater 9 is radiated through the punched holes 15 made at the outer circumferential wall 14a of the concave part 14 and thus they may be heated substantially in the equal degree as that of other portions of the heated material 2.
