IPC: H04N5/91
Filed: 1989-10-31
Abstract: PURPOSE:To record an event caused concentratingly for a period other than a recording period by applying time base compression multiplex to input audio information for a prescribed period corresponding to intermittent video information within a vertical blanking period of compressed video information. CONSTITUTION:An adaptor is in the operating state in the state before recording and a video write control means means 10 is in the write control information mode and generates a timing pulse and a write address signal intermittently at a period of 0.5sec (30 fields). Thus, the input video information is digitized as intermittent video information by a 1st AD conversion means 12 and stored in a video memory 14 by 18 fields. In the case of the storage, the input audio information by nearly 0.5sec in preceding over each intermittent video information is compressed by nearly 1/500 with respect to the time base and the result is stored in a relevant address for the vertical blanking period of the intermittent video information. Thus, the video information and the audio information highly possible to lose the recording are surely stored.

Title: Filament nonwoven fabric and its production
Inventor: TSUBATA MASARU
IPC: D04H1/544
Filed: 1991-10-03
Abstract: PURPOSE:To provide a filament nonwoven fabric having high bulkiness and flexibility and to provide a process for producing the fabric. CONSTITUTION:A fiber-forming thermoplastic resin S1 is melted in an extruder 1 and a mixture S2 of the resin S1 and inorganic compound powder S3 is melted in an extruder 2. The molten materials S1 and S2 are separately supplied to a spinneret 3 and extruded in separate state through a pair of nozzles 6, 6' of a side-by-side conjugate spinning die 5 of the spinneret 3. The extruded materials S1 and S2 are bonded with each other immediately after extrusion to form a side-by-side conjugated filament. Since the component S2 contains the powder S3 functioning as a crystal nucleation agent, the crystallization of the component S2 is accelerated compared with the component S1. Accordingly, the crystallization degree and the volume shrinkage of the component S2 are higher than those of the component S1 during the period from the molten state to the solidified state. Consequently, the obtained conjugate filament is crimped in such a manner as to face the component S2 inwardly. A filament nonwoven fabric is produced by collecting the crimped filaments.
