Patent JP-S61276176-A (JP)
Title: Data processing method
Inventor: OGAWA HIROSHI
IPC: G11B20/18
Filed: 1985-05-31
Abstract: PURPOSE:To decrease the quantity of data which are lost by errors by providing the synchronizing signals at the front and rear parts of a data block having the prescribed bit length and correcting the data arraying order at and after a defective part of the reproduction data in response to the detecting position of the synchronizing signal at the rear part. CONSTITUTION:The front synchronizing signal PRD of (a) bits having a prescribed bit pattern is recorded on a disk at the head part of data equivalent to a frame together with the rear synchronizing signal POD of (b) bits having a prescribed bit pattern recorded at the end part of an n-bit data block. In a reproduction mode an address counter of a RAM to which the reproduction signal is written is started by the signal PRD. Thus the difference is obtained between the address obtained when the signal POD is detected and a prescribed number of clocks obtained in a frame period and then recorded. At the same time, the defect and its position of the reproduction signal are detected and stored. In a read mode of the RAM the reading is carried out in a normal way up to the position where a defect is produced. Then the addresses are corrected by the obtained difference at and after the defective position. Thus the quantity of data lost by errors can be reduced.

Title: Video tape recorder
Inventor: SUZUKI MITSUYOSHI
IPC: H04N5/91
Filed: 1989-05-11
Abstract: PURPOSE:To record only a required picture efficiently by storing a final picture data recorded on a tape into a frame memory and stopping the video recording when a difference between the stored data and the input picture is small. CONSTITUTION:When an external switching input 16 is selected to 'monitor', a switch 11 sends OFF to a controller 6 as it is when a video recording operation input 8 is at 'OFF' to stop the operation and when the video recording operation input 8 is at 'ON', the operation depends on a moving detection output 19 representing whether or not there is any movement in the picture. A frame memory 14 writes a new picture data 17 and revises it only when a moving detection output 19 is ON (with movement) and a final recording picture to be recorded on a magnetic tape 5 at all times and the final recording picture data 18 is inputted to a computing element 15. Thus, the part without any motion is eliminated from the recorded picture and the picture is recorded with deframing state to the picture moved gradually.

Filed: 1978-09-26
Abstract: PURPOSE: To search a tape at a high speed accurately by controlling a tape driving motor by generating pulses of a frequency corresponding to a search distance and then by comparing them with pulses of a frequency corresponding to a detection tape speed.  
     CONSTITUTION: In search operation, a control pulse, varying with a serach distance, of a frequency higher than that in steady run state is applied from a controller to terminal 17 and then inputted to servo circuit 29. To this circuit 29, a detection pulse of a frequency equivalent to a tape speed generated by tape speed detecting method 30 detecting the rotation of take-up reel 10b of VTR, etc., is also applied and driving motor 9b for reel 10b is so controlled that both pulse frequencies will agree each other. Therefore, motor 9b rotates faster than in the steady rotation state corresponding to the pulse frequency supplied to terminal 17 to make tape search, so that high-speed search will be performed with its initial point set accurately.

Abstract: PURPOSE:To always stably control going and return by changing the speed for going and return of read scanning in accordance with the temperature of a driving motor. CONSTITUTION:When the copying operation is started by a copy key, an optical scanning system starts going. When it goes for a required extent, the temperature of an optical system motor 115 is detected by a thermistor 116.

After the optical system returns to reach a brake control start position, the temperature of the optical system motor 115 is detected again. An extent of brake most suitable for this temperature is calculated and brake is controlled. Since the speed and brake are properly controlled in accordance with the temperature change of the motor 115 in this manner, the stop precision is improved and the variance in stop time is reduced.

Abstract: PURPOSE:To enable to augment the breaking withstand quantity at the time of reverse recovery by a method wherein an electrode smaller than an opening for heavy metal diffusion, which is provided on the insulating film of the semiconductor substrate, is formed on the surface of the anode region in the opening. CONSTITUTION:An electrode film 4A is formed in the opening 5a for polymeric metal diffusion of an insulating film 5 in such a way as not to reach up to the outer peripheral edge of the opening 5a. By this way, as the distance from the electrode film 4A to the outer edge part of a heavy metal diffusion region 2a becomes longer than that in the conventional semiconductor device, the current circuit to an equivalent diode D1 corresponding to a heavy metal non-diffusion region 2b becomes longer and the apparent resistance in the diode D1 becomes (r+R) increasing as much as a resistance R to the increased component of the current circuit. Accordingly, the forward voltage in the equivalent diode D1 corresponding to the heavy metal non-diffusion region 2b becomes larger than that in the conventional semiconductor device and current concentration is reduced. As a result, the breaking withstand quantity in the heavy metal non-diffusion region 2b at the time of reverse recovery can be improved.
