Title: Method and apparatus for pcm recording and reproducing audio signal
Inventor: ARAI TAKAO
IPC: G11B20/08
Filed: 1986-11-12
Granted: 1992-03-31
Abstract: ABSTRACT OF THE DISCLOSURE          A PCM audio signal recording and reproducing apparatus samples an audio signal accompanying with a video signal, converts it to a PCM signal, adds an error detec-tion/correction data to a predetermined number of PCM data, forms a data frame by those signals, modulates it in accordance with a predetermined modulation system, and records the audio signal together with the video signal or singly on a record medium by using a rotary head type scanner.  A digital signal processing circuit having a memory of a predetermined capacity is provided, and the number of digital data to be recorded in one data frame is varied in accordance with a difference between the number of input data of the digital audio signal to the digital signal processing circuit and the number of output data supplied to the record medium for recording.  In the record-ing mode, the PCM audio signal is sectioned into blocks, a data block address signal is added to each block to indicate a relative order to other blocks and complete in one track, certain number of blocks are combined to form a block set for processing signals, and an identification signal completing in the block and an interleave block address signal for indicating a relative order to other blocks are added to each block.

Abstract: SAFETY CLOSURE FOR CONTAINERS                 Abstract of the Disclosure A safety closure for a container having a tubular neck surrounding a passageway having an outlet aperture for pouring contents from the container, the safety closure comprising a cap in the form of an inverted cup having an outer peripheral wall and an inner peri-pheral wall concentric with the outer peripheral wall spaced apart inwardly a short distance radially of about an eighth of an inch.  A closure wall extends across the top having a closure tab hinged at one end for pivotal movement between an open and closed position.  When in the closed position it closes an aperture opening to a central cavity bounded by the inner peripheral wall, the central cavity in turn opening to the open bottom wall of the closure cap for communication with the chamber of the container when the closure cap is in place thereon.          The free end of the closure tab terminates at the peri-pheral edge of the outer peripheral wall and seats in a cut out portion thereof when in the closed position. A deflectable barrier strip is formed in the outer peri-pheral wall immediately below the cut out portion, the free end of the closure tab in the closed position abut-ting against the upper edge of the deflectable barrier strip forming a lateral crack therebetween.  The outer portion of the upper edge of the barrier strip includes an upwardly extending flexible nib therealong which covers that crack and prevents inserting anything therein to pry up the free end of the closure tab.  In order to gain access to the free end of the closure tab for opening, the deflectable barrier strip has to be pressed inwardly whereupon a portion of the closure tab is bared for pushing upwardly to the open position.
