IPC: B65B51/10
Filed: 1992-09-09
Abstract: PURPOSE:To prevent the occurrence of excessive melting and incomplete welding of a plastic film for package by a method wherein a heat roller of heat pipe structure in the inside the temperature of which is controlled to a given value is arranged in front of a sealing mechanism. CONSTITUTION:In a heat roller 3, a plurality of heat pipes 14 are fitted in the interior thereof coaxially of a heater 13 fitted in a central axis-form manner. The arrangement is worked to balance dispersion of the temperature of the heater 13 and dispersion of the heat roller 3 is suppressed to a minimum.

Title: Device for compacting powder
Inventor: NASU TOSHIYUKI
IPC: C10B45/02
Filed: 1985-11-28
Abstract: PURPOSE:To attain noise elimination, maintenance work simplification and cost reduction, by equipping a compacting member with a secondary side conductor as a needle and a stator facing the conductor with a gap, thereby permitting application of AC. CONSTITUTION:Applying AC to a coil 20 of a stator 17 leads to occurrence of magnetic flux phi. This magnetic flux phi causes an induced current Ie to occur on an induced current plate 16, i.e., a needle. However, this current is an eddy current since the induced current plate 16 which is a conductor has a large area. Further, since the magnetic flux phi is AC, it becomes an advancing magnetic field wave. This advancing magnetic field wave brings about a thrust in cooperation with the eddy current. The stator 17 is fixed to a protruded portion 13a, so that the induced current plate 16 moves in the X direction as a needle. As a result, a rod 8 is elevated. After elevating the induce current plate 16 to an extent as needed in this manner, if passage of current to the coil 20 is discontinued, elimination of the magnetic flux phi and thus extinction of the thrust result. Then the rod 8 freely falls, thereby causing dust coal to be compacted by means of the lower surface of a foot 7.

Title: Sync signal detecting system for rotary head type tape recorder
Inventor: TAKI TETSUYA
IPC: G11B15/467
Filed: 1987-10-23
Abstract: PURPOSE:To limit the duration of a blind sector by discriminating the regularity of a reproduced sync signal when said regularity does not coincide with a preliminarily set regularity, and modifying the set regularity based on the result of said discrimination. CONSTITUTION:A reproduced signal is equalized of its waveform by the equalizer 6 of a sync signal detecting part 5, then converted to a digital signal by a zerocross comparator 7. A control logic circuit 8, when the regularity of this signal and the preliminarily set regularity do not coincide with each other, starts a regularity retrieval, and discriminate the regularity of the reproduced sync signal, and based on the result, modifies said preliminarily set regularity in order to discriminate the regularity of the signal. When this discrimination is impossible, the system is maintained in a state SRQ=1 where only such one of the sinc signals detected subsequently that includes no miss sync for a length of 1r is recognized as a sync signal until the regularity can be discriminated.
