Title: Clock selecting circuit
Inventor: YAMAZAKI HAJIME
IPC: G06F1/06
Filed: 1982-03-30
Abstract: PURPOSE:To always select and deliver a correct clock and to improve the reliability of a clock selecting circuit, by selecting the clock based on the change of states between break and recovery of the clock as well as on its immediately preceding state. CONSTITUTION:Output signals ''1'' and ''0'' of break detecting circuits DET1 and DET2 and storage contents ''0'', ''0'' and ''0'' of a memory MEM are added to a decoder DEC after delay times of delay circuits DL1 and DL2. Thus the output signal of the decoder DEC is set at ''1'' on the basis of a decoding logic table of the figure 4. Therefore a selector SEL selects and delivers a clock CLK2. When this clock CLK2 is recovered after clocks CLK1 and CLK2 of both systems are broken, storage contents ''1'', ''1'' and ''1'' of the MEM showing the immediately preceding clock state and output signals ''1'' and ''0'' of the circuits DET1 and DET2 which are obtained via the circuits DL1 and DL2 are applied to the DEC. Thus, the decoding output is set at ''1'' in accordance with the decoding logic table. Therefore the SEL selects and delivers the CLK2.

Title: Reel device
Inventor: FUJII HIROSHI
IPC: G11B15/18
Filed: 1993-03-12
Abstract: PURPOSE:To lighten the collision to a tape at the time of stop by reducing the number of components cutting the driving force of a reel base. CONSTITUTION:Centering parts 3, 4 centering an oscillating arm 47 are provided on brake arms 1, 2. When a mode is changed to the stopping mode from the running mode, the reel bases 57, 58 are braked by the brake arms, and simultaneously pundulum gears 52,53 are separated off from the reel bases by the centering parts to cut the driving force of the reel bases. Since the driving force of the reel bases is cut in the centering parts provided on the brake arms, the arrangement of a separately provided member like as the conventional manner is unrequired, thereby the number of components are reduced. Similarly, the deviation between the time to brake and the time to cut the driving force of the reel bases is eliminated, therefore, the large driving force is not applied to the tape at the stopping time.
