Title: Tracking controller for rotary head type tape recorder
Inventor: TAKI TETSUYA
IPC: G11B15/467
Filed: 1987-04-20
Abstract: PURPOSE:To perform stable tracking control by changing the detection gain of the tracking error signal between the levels of this signal are higher and lower than the reference value based on the integration value of the tracking error signal. CONSTITUTION:The tracking error signal voltage es produced by adding a fixed level of voltage corresponding to the offset value to the difference of levels between the pilot side read signals received from right and left adjacent tracks is applied to an operational amplifier 10 together with the reference voltage -er set by a variable resistor VR1. In this case, the gain of the amplifier 10 is changed by the difference between the tracking error signal es and the reference voltage -er. Thus it is possible to correct the S-curve characteristics obtained in an offset tracking state or a tracking state where the steady deviation is secured into the satisfactory characteristics. Then the stable tracking control is carried out.

Title: Continuous production of water- and/or oil-impermeable sealing sheet
Inventor: GEORUKU HEERUTEN
IPC: E02B3/12
Filed: 1993-04-02
Abstract: Described is a process for the continuous production of a water- and/or oil-impermeable (impervious) liner (sealing matt) wherein expansive (swellable) clay is needled into between a carrier layer and a nonwoven top (cover) layer while at the same time an expansive clay additionally sprinkled onto the upper surface of the top layer is incorporated into the top layer. Subsequently the expansive clay present in the top layer is incipiently moistened and re-dried. A modified embodiment uses only a carrier layer made of a nonwoven, woven fabric or knitted fabric and/or a foil, the foil being a plastic film, a fabric-reinforced plastic film or paper, and a coarsely porous nonwoven or a non-consolidated crosslaid (fibre-crossed) card web or a random-laid fibre web, to which the pulverulent expansive clay is applied and needled in, moistened and dried. Instead of the needling technique it is also possible to use the knitting and/or sew-knitting technique.

Abstract: PURPOSE:To provide excellent dynamical properties to a film and especially enhancing the modulus of elasticity thereof at high temp. and to impart enhanced heat resistance and high temp. dimensional stability thereto, by a method wherein a raw film. which was thermally stretched to the lateral direction, is subjected to zone stretching under tension under local heating and further subjected to one stage or multistage heat treatment while locally heated at temp. in the vicinity of crystallization temp. under high tension. CONSTITUTION:A raw film according to an extrusion method is thermally stretched to the lateral direction to be converted to morphology facilitating zone stretching. By this operation, lamella is arranged in a state stacked in the lateral direction and takes an azimuth wherein a folded chain crystal structure is easily unraveled by external force in the longitudinal direction. Subsequently, zone stretching performed in the orthogonal direction is performed while the film is passed through a narrow heating zone while locally heated. Further, by applying zone heat treatment to the highly stretched and ultimatelly extended chain structure obtained by zone stretching at temp. suitable for crystallization, a film having not only enhanced dimensional stability but also high modulus of elasticity and high strength is obtained.
