Title: Tracking control system of step track device
Inventor: KAMAO YOSHIYUKI
IPC: G01S3/44
Filed: 1985-03-20
Abstract: PURPOSE:To prevent a tracking error even when the change occurs at the incoming electric wave by providing the difference between the receiving level to start an antenna tracking and the receiving level to stop an antenna tracking. CONSTITUTION:The output of a receiving device 10 is applied through an LPF 2 to an integrator 3, integrated for a constant time while an antenna 11 is standstill, next, sampling-processed 4 and stored 5. An arithmetic processing part 6 calculates the difference of a receiving signal level before and after the antenna is driven, decides the positive and negative and transmits the control signal to a driving device 12. Presently, when the automatic tracking is stopped, a stop level deciding circuit 8 is operated, and the automatic tracking is restarted from the untrackable condition, the difference between the level to restart the tracking and the level to stop the tracking is set larger than the level to descend when the antenna 11 drives by one step, and again, it can be prevented that the antenna 11 is driven to a stop level or below. Even when the change of the incoming electric wave strength is large, the increase in the tracking error can be prevented beforehand.

Abstract: PURPOSE:To contrive the high speed of an interpolation processing by selecting the addresses of three points by means of a decimal part address value, preparing a coefficient for the selected three points, reading the data of the three points, and obtaining the inner product of the three point data and coefficient. CONSTITUTION:Two-dimensional real number coordinates (X, Y) are separated into integer part addresses (x, y) and decimal part addresses (Kx, Ky), and based on the value of the decimal part addresses (Kx, Ky), the three point addresses to be used for interpolation are selected out of (x, y), (x+1, y), (x, y+1) and (x+1, y+1). Next, the coefficient for the selected three points is prepared, and the inner product of the three point data and the three point coefficient is obtained. That is, the two-dimensional real number coordinates are separated to the integer part addresses and the decimal part addresses, the three point addresses are selected based on the value of the decimal part addresses, the coefficient for the selected three points is prepared, the three point data are read, and the inner product of the three point data and coefficient is obtained. Thus the two-dimensional data of the real number coordinates can be interpolation-processed at high accuracy and at high speed.

Title: Optical recording medium
Inventor: MORIYA MITSUROU
IPC: G11B7/24085
Filed: 1984-03-26
Abstract: PURPOSE:To easily adjust a focal point controlling system to the best condition when the condition of the system varies, by previously providing a converging condition adjusting signal which confirms the condition of the focal point controlling system and adjusts the system to the best condition when the condition varies. CONSTITUTION:When spiral recording tracks for adjusting converging condition are installed at least more than one round in the vicinity of the outer periphery on a recording medium 10' and an optical beam 6 is irradiated and, at the same time, focal point control is made, a signal is obtained at a summing circuit 21 which outputs the summed signal of a split light detector 11. Since the recording track is traversed by one time for every rotation when the recording medium 10' is not eccentric, one piece of signal output is obtained. When the recording medium 10' is eccentric, plural signal outputs are obtained, because the recording track is traversed many times for every rotation. Moreover, the signal output 22 depends on the spot diameter of the optical beam 6 on the recording medium 10' and when correct focussing is made, namely, when the optical beam 6 is correctly converged, the spot diameter becomes the minimum and the signal output becomes the maximum.

Title: Lens driving device
Inventor: MORIKAWA TOSHINORI
IPC: G02B7/10
Filed: 1990-03-09
Abstract: PURPOSE:To drive the moving frame for a zoom lens in a small space by providing a zoom motor which engages the gear of a screw shaft and locking a nut member so that the nut member can be shifted in position by the moving frame for the zoom lens at right angles to the optical axis. CONSTITUTION:When the screw shaft 34 rotates, the zoom lens moving frame 11 coupled with the nut member 36 engaging the screw shaft 34 moves in the direction of the optical axis. At this time, the zoom lens moving frame 11 is supported by two guide poles 10 and moves integrally with the nut member 36. For the purpose, the clearance DELTAL between a collar 37 and the cut surface of the nut member 36 is made large. The nut member 36 can, therefore, be shifted in position at right angles to the optical axis and the influence of the low accuracy of the screw shaft 34 upon the position accuracy of the guide poles 10 and screw shaft 34 about the zoom lens moving frame 11 can be reduced. Consequently, the zoom lens moving frame 11 can be driven in the small space.
