Title: Cover tape for packaging chip-type electronic component
Inventor: NAKANISHI HISAO
IPC: B65B15/04
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent conventional sealing characteristics from degrading and also easily confirm contents by coloring a cover tape which can be heat-sealed on a plastic carrier tape continuously formed with housing pockets for receiving a chip-type electronic component. SOLUTION: The cover tape 1 comprises an outer layer 2 made of a biaxially oriented film which is either polyester, polypropylene or nylon, an intermediate layer 3 made of a polyethylene film and a heat-seal layer 4 made of thermoplastic resin. Which layer of the cover tape 1 to be colored and its color is not especially limited, wherein any color can be used. However, a color other than that of the carrier tape is desirable, while a color other than black is more desirable. Although transmissivity of visible light may not be improved due to addition of pigment or the like, since the color of the carrier tape is often black, contents looks more clear due to complementary color effects.

Abstract: PROBLEM TO BE SOLVED: To obtain a wide capture range by detecting a phase and the length of a pulse signal as digital signals to recover a bit clock from a data flow and using the result of summing and integrating the signals for a tuning signal for a PLL. SOLUTION: A phase P is fed to a phase detector 1 and the length L of a pulse is fed to a pulse length detector 2. The pulse length detector 2 inputs information representing a side edge of the pulse to be a rising state or a falling state (R/F) and a control signal from a control unit (not shown) in addition to the pulse length L. Output signals from the phase detector 1 and the pulse length detector 2 are added by an adder 4, and its sum is multiplied with (a coefficient -1) in a case. The output signal 6 of an integration device 5 obtained in this way is used for the returning value of a frequency oscillator of a PLL. Thus, a bit lock PLL with an improved capture characteristic is realized.
