    摘要: A process for producing a graphite block from a plurality of graphitizable polymer films or a plurality of carbonaceous films separately obtained from graphitizable polymer films is described. The method comprises superposing the plurality of the graphitizable polymer films or the plurality of the carbonaceous films, and thermally treating the plurality of the graphitizable polymer films or the plurality of the carbonaceous films in a substantially compression pressure-free condition when the treating temperature is in the thermal carbonization temperature range and the graphitization temperature range and under compression pressures in temperature ranges between the thermal carbonization temperature and the graphitization temperature ranges and over the graphitization temperature range. The compression pressure over the graphitization temperature range should be higher than that in the range between the thermal carbonization and graphitization temperature ranges. By this, a wrinkle-free graphite block with a good rocking characteristic is obtained.

    摘要: A moving coil type pickup cartridge comprises at least two movement-electromagnetism conversion systems functioning in push-pull mode, each system being arranged by a coil supported on a plate and inserted in an air gap between two opposing magnet blocks each constituted by side-to-side two magnets so as to provide opposite magnetic poles facing each other with the air gap intervening therebetween. A linear movement of the coil is allowed in the air gap in the directions of cutting the magnetic fluxes in the magnetic fields produced between the opposing magnet blocks. This arrangement provides a high density of magnetic fluxes and a high output voltage and improves the quality of signals reproduced. This effect is promoted further by yoke plates of a material of high magnetic permeability arranged to straddle the open magnet poles of the side-to-side magnets, thereby inhibiting leak of magnetic fluxes from these open poles. Vertical compliance of the vibration system can be made small during tracing a warped record disk by the use of an asymmetrically shaped armature. Good contact of damper to armature can be secured by fitting the armature into the damper. This cartridge may be made integral with head shell.
