摘要:
A heating plate is disclosed which is adapted for use in a dryer for drying a sheet of wood veneer by heating said plate at a desired level and placing one surface of the plate on either side thereof in engagement with the veneer sheet. The heating plate, when heated and placed in non-engagement state, is formed such that said one surface is convex shaped.

A rewrite determining unit acquires, for every servo frame recorded on a magnetic disk, an amplification degree, i.e., a gain of an amplifier circuit by which a read signal read from the magnetic disk is amplified to a predetermined output, determines a rewrite sector count based on the amplification degree, and performs data rewriting according to the rewrite sector count.

A waveguide type variable optical attenuator is provided with a substrate for forming a waveguide for optical signal propagation; a waveguide element comprising 2 arm waveguides arranged on the surface of the substrate for constituting a portion of the waveguide and cladding for covering the arm waveguides and the surface of the substrate; and a heater arranged on the surface of the waveguide element for heating the arm waveguides. The 2 arm waveguides are connected thermally.

A head-slap detecting device detects a head slap. The head slap causes a storage medium to be slapped by at least one storage-medium driving unit that performs at least one of reproduction and recording of data from and to the storage medium. The head-slap detecting device includes a detecting unit that detects the head slap by determining whether a first variable gain obtained from a variable gain amplifier that amplifies an output of data reproduced by the storage-medium driving unit exceeds a predetermined threshold.

A method and apparatus of manufacturing glued laminated wood such as laminated veneer lumber (LVL) are disclosed. The glued laminated wood is made of a number of wood sheets such as veneer sheets which are laminated together by a hot press with a thermosetting adhesive into a continuous length of multiple-layered board of the glued laminated wood wherein wood sheets in each layer of the multiple-layered board are arranged in a staggered relation in the lengthwise direction of the board to wood sheets in an adjacent layer. The hot press has a pair of heating plates arranged substantially in facing relation to each other and an auxiliary heating plate disposed adjacent to one end of each heating plate. The auxiliary heating plate is adapted to press part of wood sheet which extends out beyond the above end of the heating plate.
摘要:
A method and an apparatus of wood pressing usable in manufacturing glued laminated wood such as laminated veneer lumber (LVL) using a number of wood veneer sheets are disclosed. A hot press used for wood pressing includes a pair of heating plates which are disposed one above the other and have pressing surfaces facing each other. The paired heating plates are both movable toward and away from each other. In operation, firstly one of the heating plates is moved toward the other heating plate to a position where the pressing surface of the one heating plate is spaced from a surface to which a veneer sheet is to be glued by a distance corresponding to the thickness of the veneer sheet. Then, the other heating plate is moved toward the one heating plate until a desired pressure is produced pressing.

When a combination head is on-tracked to an arbitrary cylinder position, a head position controller corrects a head position so as to eliminate an offset amount derived from an offset table. A bias current setting circuit obtains a current set value corresponding to an offset correction amount from a bias current table and supplies the bias current according to the current set value to an MR head. As kinds of offsets, there are a yaw angle offset, a thermal offset, and a core deviation offset.
