Title: Lens barrel
Inventor: IWASAKI YOICHI
IPC: G02B7/04
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To instantaneously normalize the relationship between the current position of an objective lens group and the drive amount of a driving device after external force and an obstacle are removed by detecting the current position of a holding frame of the objective lens group and controlling the operation of the driving device. SOLUTION: A current position detecting means 20 is an absolute position encoder, and the output has a one-to-one correspondence to the position of a first lens group 1. During picture non-recording operation, the zoom position deviation is detected, and when picture recording is interrupted after a zoom position deviation is detected during picture recording operation, the current Z pulse count value is stored in a memory. Subsequently, the direction of the Z-initial position is judged from the output of the current position detecting means 20, and the Z motor 10 is driven until a Z sensor detects that the first lens group 1 reaches the Z initial position. On detecting the Z initial position, the Z pulse count value is reset to a numerical value of the Z initial position and counting is restarted. The Z motor 10 is further driven until the Z pulse count value agrees with the current Z pulse count value stored in a memory.

Abstract: PURPOSE:To eliminate the loss of the data due to shortage of ink and decrease the consumed power of the electric circuit by providing a light emitting device at an end of a recording pen of hygrometer and the like and electrically detecting the movement thereof by a plurality of arranged photoelectric transducers. CONSTITUTION:A light emission diode LD attached to an end of a movalbe pen such as a recording pen is arranged in an opposite relationship to longitudinally arranged phototransistors PT1-PT11.

Title: Two-screen television receiver
Inventor: ISHIDA MAKOTO
IPC: H04N9/77
Filed: 1985-01-18
Abstract: PURPOSE:To decrease color shifts due to temperature changes or aged changes and to realize the system suitable for circuit integration by applying sampling while shifting a delay time corresponding to a delay circuit at the sampling point of time of an A/D converter and shifting the sampling point of time of a color difference signal to a luminance signal to correct the delay time. CONSTITUTION:Sampled luminance signal data is written sequentially on a 1H memory 6a during the 2nd horizontal scanning period and a color difference signal data is written sequentially on 1H memories 6b, 6c. The data stored in temporary storage means 6a, 6b, 6c is read in the 3rd horizontal scanning period. A read clock of the luminance signal data is read by the same clock as the write clock, and since the read clock of color difference signal data is obtained by applying 1/4 frequency division to a basic clock generating the read clock of the luminance signal by a frequency division circuit 11, the data is read as soon as the 1st luminance signal data in one unit is read. Thus, the color difference signal retarded by the luminance signal is corrected at signal demodulation by reading the data from the temporary storage means.
