Title: Cutting tool for optical fiber
Inventor: OSAKA KEIJI
IPC: G02B6/24
Filed: 1984-12-21
Abstract: PURPOSE:To cut an optical fiber excellently by equalizing the length of a leaf spring to the width of a support base and constituting a rotatable optical fiber presser at the tip side of the optical fiber, and making a flaw while the optical fiber is applied with tensile force previously. CONSTITUTION:The length of the leaf spring 2 on which a rubber plate 2 is stuck is equalized to the width of support bases 1a and 1b provided at an interval, and optical fiber pressers 4a and 4b both press the leaf spring 2. Then, the optical fiber presser 4a at the tip side of the optical fiber 10 is supported pivotally on a presser body 4. Then, an initial flaw is made in the surface of the optical fiber 10 with a flawing blade 6 and then when the optical fiber 10 moves according to the flection of the spring 2 caused by the elevation of a stem 8, the optical fiber presser 4a rotates very finely to hold necessary tensile force without causing any sliding force between the optical fiber 10 and optical fiber presser 4a, thereby cutting the optical fiber excellently.

Title: Manufacture of laminated material
Inventor: HASEGAWA KATSUJI
IPC: B32B21/14
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To prevent the yielding from lowering by precisely piling up veneers and, improve the quality of a product by a method wherein the veneer, after the front and rear sides of which are dried by being urged with heating bodies for the specified period of time, is split in the direction of the thickness of the veneer into two so as to bond another plate material between the two split veneers. SOLUTION: The time for urging heating bodies 5 and 6 against the front and rear sides of a veneer 50 is set for drying to be shorter than the time necessary for obtaining the water content at the middle in the direction of the thickness of the veneer 50 less than its fiber saturation point by being dried through the urging of the heating bodies. Next, by splitting the veneer 50 in the direction of its thickness into two veneers 50a and 50b. Then, a middle plate 51 is arranged through an adhesive between the two veneers 50a and 50b under the condition that the split surfaces of the veneers 50a and 50b are faced outwards and their cross grains are set to be almost the same. Next, by urging the heating bodies of hot presses from the respective split surface sides, the two split veneers 50a and 50b and the middle plate 51 are bonded together into a plywood 52.  Since the forces in the veneer 50a side balances with that in the veneer 50b side about the middle plate 51 as the center in the resultant plywood 52, the twisting of the plywood becomes small.

Title: Keyboard device and its manufacture
Inventor: KUMANO SHINJI
IPC: G10B3/12
Filed: 1998-09-25
Abstract: PROBLEM TO BE SOLVED: To obtain an excellent touch sense at the time of key operation corresponding to how strongly a key is pressed by making a large-mass moving member longer in the movement distance of the mass center and larger in mass than a key and an intermediate moving member. SOLUTION: The mass center M30 of a 1st moving member 30 is positioned slightly behind the center of the overall length. A 2nd moving member 50 is formed of plastic, has lead, etc., embedded in its tip part 53, and is large in mass and the mass center M50 is partial to the tip part. Namely, the tip part 53 which has a large movement distance is given large mass and the position of the mass center M50 is positioned behind the center R50 of rotation so that the 2nd moving member 50 returns gravitationally from its rotational position. The 2nd moving member 50 which is associated with the key at the time of key operation is larger in the movement distance of the mass center and larger in mass than the key 20 and 1st moving member 30. A large inertial force is therefore obtained with efficiency and large inertial resistance can be obtained by giving relatively small mass.

The fine adjustment of the pressure inside the vacuum processing chamber 9 by plasma ripple during processing, the phased setting or pressure, and others are controlled by the other pressure control valve 4b. According to this, since the processing start pressure is set with one pressure control valve 4a on the proceeding pressure control valve 4a, and the delicate pressure control during processing is performed with the other pressure control valve 4b, the stable pressure control at vacuum processing at low pressure or the control of the pressure fluctuation within the vacuum processing chamber 9 due to plasma processing becomes possible.

Title: Input signal break detecting circuit
Inventor: IKUSHIMA ICHIRO
IPC: H04L69/40
Filed: 1991-10-21
Abstract: PURPOSE:To enable stable input signal break detection relating to a sign error without any adjustment. CONSTITUTION:The sign error output 9 is integrated by an integration circuit 5, whose output is compared by a comparing circuit 8 with a reference voltage 11 to generate an input signal break detection output 3. The integration circuit output is proportional to the sign error, so the input signal break detection relating to the sign error becomes possible. A capacitor 7 is interposed between the inputs of the comparing circuit to prevent malfunction in the input signal break detection even in the case of an accidental sign error increase. Thus, the signal generated by integrating the sign error detection output is used, so the input signal break detection correlating with the sign error is possible. Further, the sign error detection consists of a digital circuit, so the need for adjustments of the input signal break detection is eliminated.
