Title: Apparatus and method for producing alternately twisted yarn and obtained product
Inventor: DONARUDO AARU HARAMU
IPC: D02G3/04
Filed: 1989-04-15
Abstract: PURPOSE: To obtain alternate twist plied yarn having a long twist inversion length by progressing a specific alternate twist plying stage of plural strands at a prescribed speed under tension in paths adjacent to each other. CONSTITUTION: The plural strands are heated in alternating directions by a torque jet 20 under tension. Yarns are ply-twisted as they leave the torque jet 20. The yarns are compressed and are bonded to each other by an ultrasonic horn 26 and an anvil 27 while their advance is periodically stopped. The strands are twisted respectively in the same opposite directions by a single booster torque jet 28. The ply-twisted yarns 30 are accelerated and decelerated by take-off rolls 40. The yarns are heated and are fixed to the ply-twisted shape by a heating tunnel 56.

Title: Automatic focus detector
Inventor: FUJIWARA AKIHIRO
IPC: G01S17/46
Filed: 1983-05-30
Abstract: PURPOSE:To save electric power and to increase a detection speed by deciding on focusing speedily when the integral value of the output of a photodetecting element attains to a focus detectable level. CONSTITUTION:Light emitted from a projected element 3 passes through b1 to strike an object, and is reflected irregularly to pass through an optical path b2, forming an image on a photodetecting element 6. When the image is in focus, the reflected light of the projection spot image P is photodetected in two areas 6A and 6B on the sensor with the same quantity of light, and the integral values VA and VB of their outputs have no difference. When the image is not in focus, the integral values have difference, so the photodetecting element 6 is moved until the difference is eliminated to move a lens 1 associatively. For the purpose, a means which detects the integral values attaining to a specific level and a means which detect the large/small relation between both integral values VA and VB exceeds the specific level are provided, and a focusing decision is made immediately when one of the detecting means operates.

Title: Optical branching coupler
Inventor: TOKURA NOBUYUKI
IPC: G02B6/293
Filed: 1982-06-05
Abstract: PURPOSE:To obtain an optical branching coupler, by using a polarizing filter which divides light into two parts. CONSTITUTION:An optical fiber 21 is set at the left of a branching polarizing filter 29 and a coupling polarized filter 28 in parallel to the filter 29 at the other side of the filter 29. Furthermore, an optical fiber 23 is provided to form a coupling input optical path going toward the filter 28. Then optical fibers 22 an 24 pick up the reflected beams of both filter 28 and 29. In such constitution, the fibers 22 and 24 are not set on the same straight line and therefore the P wave delivered from the fiber 23 never enters the fiber 22. It is possible to obtain an optical branching coupler having such an effect even by use of a relfector 30.

Abstract: PURPOSE:To constitute the screen editor so that it does not take time for completing a program source by executing a grammatical check in a program source generation process, and informing a grammatical error to a user at the time when it is detected. CONSTITUTION:Whenever symbol information which is displayed on a screen 4 and can be mentioned in an input area 6 with a format prompt is inputted by one line, a simple grammatical check of input symbol information is executed by referring to grammatical check data stored in a file.

Title: Electronic clock
Inventor: ICHIKAWA MASAKAZU
IPC: H02J7/02
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To make it possible to drive a clock in safety without causing overcharging voltage, by, if the voltage of a small-capacity accumulating portion is sufficiently higher than that of a large-capacity accumulating portion when distributed charging is being performed, continuing to charge the small-capacity accumulating portion and discharging power from a generating portion to the large-capacity accumulating portion. SOLUTION: In block 2', a small-capacity accumulating portion and a large-capacity accumulating portion are alternately charged with charging current HD from a generating portion. In block 2'-1, the small-capacity accumulating portion is charged. In block 2'-1, the small-capacity voltage VCS of the small-capacity accumulating portion does not exceed overcharging voltage VO despite large charging current. In block 2'-1, the large-capacity voltage VMT of the large-capacity accumulating portion is also charged. This is because if a large voltage difference is produced between the small- capacity voltage VCS and the large-capacity voltage VMT, the electric charge accumulated in the small-capacity accumulating portion is moved to the large-capacity accumulating portion by a discharging means. Therefore, the large-capacity accumulating portion is charged as well and the large-capacity voltage VMT is increased even though the generating portion is charging the small-capacity accumulating portion.
