Title: Adhesive seal
Inventor: KUWABARA YOSHIMORI
IPC: C09J7/02
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To facilitate the peeling when opening or closing a package bag lid or the like by utilizing difference between the adhesive layer at a void having a distance corresponding to the thickness of a punched cover sheet having the void at a part thereof, and the surface of the material to be adhered. SOLUTION: This adhesive seal is obtained by laminating a peelable sheet 1, an adhesive layer 2, an adhesive substrate sheet 3, an adhesive layer 4, a punched cover sheet 5 having a void 7 at a part thereof and a peelable sheet 6. When the adhesive seal is used for a package bag, the adhesive seal is used by peeling and removing the peelable sheet 1 from the adhesive seal, adhering the removed adhering seal to the bag body, and when closing a lid, peeling and removing the peelable sheet 6 from the adhered adhesive seal, covering the adhesive seal with a folded lid from the upper side, pressing the covered part from exterior to adhere the adhesive seal 11 to a material to be adhered. When opening the sealed part, the lid is easily peeled off because the adhesive strength between the lid and the adhesive 4 is weak at the void 7.  The opening and closing operation can be repeated as far as the adhesive strength of the adhesive 2 is retained.

Title: Radiation treating device and method of material
Inventor: UIRIAMU BII NIYUUBAAGU
IPC: B29B13/08
Filed: 1988-05-19
Abstract: PURPOSE: To efficiently manufacture monomeric particles by treating a polymeric fluid solid polytetrafluoroethylene material by radiation while cooling and stirring it. CONSTITUTION: Coarse powder or a chip-like material composed of unused or scrap polytetrafluoroethylene is placed in a container 12 and is stirred by a stirrer 16 while irradiating it with an electron beam to be supplied from an electron source 44. The electron beam coming from the electron source 44 is spread in the direction along the container 12 by manipulating it in a vacuum passageway 46. The rotary stirrer 16 circulates the material for uniform irradiation. The electron beam is emitted from a sector horn through windows 58, 66. Emission of the electron beam coupled with the stirring action by the stirrer 16 of a ribbon blender causes the decomposition of the material into powder with a molecular weight of about 1 MM or less as crushings.

Title: Servo controller for optical disk drive and control method thereof
Inventor: KO HOBIN
IPC: G11B7/09
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To realize precise focus and track control by separately performing gain adjustment of an error signal at the beginning of operation without obtaining information of light reflected from a disk and after an error value arrives at a prescribed target value. SOLUTION: In a first control stage executed at the beginning of operation, an RF sum signal is outputted from a first switching part 70, and the error value is adjusted to be within the prescribed target value by the signal outputted from an automatic gain adjustment part. That is, the error signal generated in a light detection part 10 and passing through an operation part 30 is multiplied by a prescribed value in the automatic gain adjustment part 40 by having its result value divided by the RF sum signal. Thus, even when light quantity incident on the light detection part 10 is changed drastically, the error signal adjusted within the fixed gain is obtained.
