Title: Easy opening envelope for letters - has thread with outwards projecting end positioned in opening edge of closing flap to cut along fold line
IPC: B65D27/38
Filed: 1976-10-21
Abstract: An envelope is designed to accommodate letters. It includes along the opening edge of a closing flap (11) a thread (12). This thread is arranged so that it projects with at least one end on the outside of the envelope. To open the envelope the end of the thread is pulled upwards so that it cuts through the flap of the envelope at the fold line (14).

Title: PCM audio disc recordings - allows multichannel signals to be modulated and recorded on disc with suppression of undesirable HF
Inventor: FUJITA TOSHIJI
IPC: G11B20/10
Filed: 1978-11-02
Abstract: A pulse code modulation (PCM) process is used to record audio, and in particular music, signals with a minimum of distortion. Signals from eight microphones e.g. cello, piano, violin etc., are processed over low pass filter stages (3) to suppress unwanted high frequency components and are sampled (10) before being converted to digital form (11). The sampling is performed at 47.25 kHz. Conversion is made with 13 bits accuracy and the values multiplexed (12) to a pulse code modulator (13) controlled by a 7.1949 MHz clock (14). The signals are separated by high and low pass filters (16, 17), with the low pass signals modulated (19) with an AM carrier of 3.58 MHz. The two signals are mixed (20) before being transmitted to the recording stage. The signals are recorded on a spiral groove on a disc.
