Title: Tape supply speed detector
Inventor: IBARAKI SHOICHI
IPC: G11B15/46
Filed: 1990-09-12
Abstract: PURPOSE:To accurately detect speed by providing plural guide rollers rotated by a tape, and forming roll-in air ejection groove with different ejecting directions on the circumferential planes of the guide rollers. CONSTITUTION:The guide rollers 6A, 6B are rotated centering a guide shaft 2 by friction with a tape 7. The air is rolled in the outer peripheral plane of a sleeve 6b by drift friction with the tape 7. A fishbone roll-in air ejection groove 11a is formed at the outer periphery of the sleeve 6b, and the air is introduced to the groove 11a, and it is ejected smoothly from both sides of the sleeve 6b by the inclination of the groove 11a, therefore, the frictional force of the tape 7 with the sleeve 6b can be sufficiently maintained. Thereby, since either the guide rollers 6A, 6B is always rotated surely synchronizing with the supply of the tape, the supply speed of the tape 7 can be accurately detected by photointerruptor 10.

Title: Image signal band compression system
Inventor: ASHIBE MINORU
IPC: H04N19/132
Filed: 1987-09-24
Abstract: PURPOSE:To suppress a change in mode which causes deterioration in picture quality by performing mode determination by using an interpolation error variation quantity. CONSTITUTION:For example, an image is divided into blocks and modes are determined by the blocks; and there are two modes, i. e. mode 1 and mode 2. In this case, the in-block sum S of absolute values of interpolation errors in the mode 2 is calculated to assign a mode which is one field before to blocks whose variation quantities DELTAS between fields of the S are smaller than a certain given threshold value Ts and determine a mode newly for blocks whose DELTAS are larger than the Ts. In this case, once the mode 1 is entered, there is no mode change when an interpolation error varies slightly under the influence of, for example =, a noise. Consequently, a mode is determined by using the interpolation error variation quantity DELTAS, so that no mode change is caused by slight variation in interpolation error.
