IPC: B27N3/04
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To provide the technique for stabilizing the dimensions of a wood fiberboard which prevents bacterial/verminous damage from occurring without the use of a formalin resin adhesive, and is highly productive and of improved quality and further, is advantageous in terms of cost. SOLUTION: The wood fiberboard is made of wood fibers impregnated and interlocked with a glyoxal resin and an agent, integrally molded through a resin adhesive other than a formalin resin. This wood fiberboard is manufactured by coating the wood fibers with the glyoxal resin, the agent and the resin adhesive other than the formalin resin individually or an mixture obtained by arbitrarily mixing these ingredients, during splitting a wood material or in a mixing device or an air feed pipe after the splitting work, and thermally drying the coat so that it is interlocked with the wood fibers. After that, the wood fibers thus obtained are monolithically molded through the resin adhesive.

Title: Thermal printer
Inventor: FUKUSHIGE FUMIO
IPC: B41J2/36
Filed: 1984-02-20
Abstract: PURPOSE:To equalize the density of printing by absorbing dispersion of resistance values by a method in which the resistance values of resistor groups used in printing are directly detected, and voltage is controlled on the basis of the average value of the detected resistance values. CONSTITUTION:In a bridge circuit made up of heating resistors 2, 10, 11 and 12, when the resistance value of the resistor 2 is greater than a reference value, since the output voltage of an operation amplifier 15 is low, the time to reach the threshold of a monostable multivibrator 20 becomes longer and thereby the time value of the microprocessor 8 becomes greater. On the contrary, when the resistance value of the resistor 2 is smaller than the reference value, the time count value of the processor 8 becomes smaller. The detection is made for the n- numbers (a) of resistor groups 2' by the processor 8 to obtain an average value. A constant power can thus be supplied all the time to the resistor 2 on the basis of the average value by controlling the drive voltage of a voltage controller 5.

The evaluation values attain the max. values when the image-forming point of the lens L is just on a certain photodetector array and decrease as the imaging point deviates. When the imaging point deviates considerably, again the small peak of the evaluation values is made by the spurious resolution.
