Title: Contour compensating device
Inventor: WATANABE MAKOTO
IPC: H04N5/208
Filed: 1989-02-15
Abstract: PURPOSE:To improve the sharpness of a picture picked up at a low illuminance by varying a delay time by a delay means in response to an output of a mean value detection means of a luminance signal and generating a horizontal contour compensation signal based on the delay signal from the delay means and the luminance signal. CONSTITUTION:When the illuminance of an image pickup element 2 is low, the mean level of a luminance signal YH is lowered. A switching circuit 11 receives a signal from a discrimination circuit 10 and the connection is switched to input an output of a delay line 6-2 to a horizontal aperture signal generating circuit 5. Thus, the luminance signal YH inputted to the horizontal aperture signal generating circuit 5 is retarded by the delay lines 6-1 and 6-2. Thus, the luminance signal YH is retarded longer than a conventional signal by the delay time depending on the delay line 6-2. As a result, the width of the horizontal aperture signal generated by the horizontal aperture signal generating circuit 5 is increased. Thus, the S/N is improved and the noise effect is reduced and preferable contour compensation is applied even under low illuminance.

Title: Method and apparatus for measuring packing time in die casting
Inventor: MOTOMURA NORIYUKI
IPC: B29C45/77
Filed: 1980-03-21
Abstract: PURPOSE: To accurately measure a packing time for every cast product, and make possible sufficient control of casting conditions by measuring the acceleration of an injection plunger tip which force-feeds molten metal into dies, and measuring a stop signal for said tip by the change in the acceleration.  
     CONSTITUTION: A signal S f  is beforehand applied to a circuit 32, and molten metal 17 is force-fed into a cavity 14 by an injection plunger tip 18. As an increase in the force-fed molten metal, pulse signals are supplied to a detector 25 by the stripe pattern 24 of a piston rod 23. A circuit 28 receives these, measures the period of each signal and supplies the values thereof to circuits 30, 31. The circuit 31 stores the cumulative period value of the cumulative signal. When the tip 18 ends packing the rod 23 stops and just before it stops, the circuit 30 detects a period specifying value and supplies the predetermined signal to the circuits 28, 32. The circuit 32 reads the time Tn from the start of the injection of the circuit 31 til the end of the packing, and obtains the packing time T f  from this and S f  by the formula. T (n-f)  is the time from the start of injection until the tip 18 is extruded up to the molten metal gate part. The time T f  is displayed on a display 33.

Title: Recording method of pcm signal
Inventor: OZAKI SHINYA
IPC: G11B20/12
Filed: 1983-03-08
Abstract: PURPOSE:To make a smooth joint processing possible by converting an analog signal to a PCM signal and recording signals on each track so that signal components of the analog signal, which correspond to a prescribed time length, overlap signal components, which correspond to the prescribed time length, preceding and succeeding said signal components. CONSTITUTION:Rotary heads 1A and 1B are arranged at an interval of 180 deg., and a magnetic tape 2 is wound around a drum 3 in a range of, for example, 90 deg.. Consequently, a period when two rotary heads are not brought into contact with the tape 2 is generated, and in this period, redundant data is added at a recording time, and a correction processing or the like is performed at a reproducing time. As shown by Fig., signals corresponding to sections of a rotation angle of 10 deg. are written before and after a signal corresponding to a unit section of 180 deg. in RAMs 16 and 17, and they are recorded on every one track. Consequently, write control signals RWA and RWB of RAMs 16 and 17 overlap in a section of 20 deg. at the start and the end of their high-level periods (section of 200 deg.). Thus, a signal CP becomes high-level in a period corresponding to a section of 160 deg.-90 deg. in the beginning of each period, and a generation adding circuit 18 is made operated.
