Title: Paper piece holder
Inventor: SHIRATORI SEI
IPC: B42F9/00
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent a force of holding a paper piece from being lowered due to a warp brought about by the resilient force of a spring in two members so connected as to be tiltable relatively, in the case when a paper piece holder which holds, in a pressure contact, a paper piece inserted between the two members by an actuating force of the spring is formed of a synthetic resin material. SOLUTION: In a fore-end edge part 3 which extends in parallel practically to the center line of tilting connecting the respective centers of a pair of right and left bearing holes 5a and functions as a part for bringing a paper piece into pressure contact therewith, projections 7a, 7b and 7c, three in total, are provided respectively at the central part in the direction of the center line of tilting and at the parts on the opposite sides thereof, in a straight line in the direction of the center line of tilting and in a mode of projecting toward the surface of paper. According to this constitution, the resilient force of a spring acts on the surface of paper uniformly in an excellent balance and a force of holding the paper piece is increased.  The force of holding the paper piece is further increased, in particular, by making the shapes of the sections of these projections intersecting perpendicularly the center line of tilting be shaped in the letter V substantially and by making the faces of the projections on the side of the center of tilting intersect the surface of paper perpendicularly substantially.

Title: Mounting of electronic component
IPC: B23K26/00
Filed: 1992-03-19
Abstract: PURPOSE:To make it possible to inexpensively, easily and securely carry out the temporary attachment of an electronic component with an adhesive when an electronic component is subjected to surface mounting. CONSTITUTION:In a temporary attachment process prior to carrying out soldering by the immersion of a component in a solder bath, a process is provided for treating the underneath, or an attachment surface, of a diode 10 by a laser beam prior to the temporary attachment process in order to prevent the adhesion of an adhesive from being decreased because of fats and oils left on the surface of resin 11. Figure 'a' shows the diode 10 subjected to a surface treatment by a laser beam; and Figure 'b' shows a plane as viewed from the underneath, and a hatched portion is a part 20 that was subjected to the surface treatment by the laser beam. Fats and oils are removed from this surface-treated part 20, and hence a drop in the adhesion of the adhesive does not occur. This prevents the occurrence of failures such as the dropping-off of a component prior to soldering, thereby improving productivity.

Title: Magnetic recording head
Inventor: TODA YASUSHI
IPC: G11B5/127
Filed: 1981-04-28
Abstract: PURPOSE:To reduce the recording current and to achieve vertical magnetizing recording with excellent recording characteristics, by disposing a main magnetic pole with a slope by a prescribed angle from a normal plane orthogonal to a medium running direction to a recording medium. CONSTITUTION:A main magnetic pole 30 is disposed with an angle of theta to a normal plane orthogonal to a running direction 31 of an recording medium 11. A recording layer 11c runs toward the arrow 31 between both magnetic poles to the main magnetic pole 30. The recording layer 11c is vertically magnetized with a magnetic field 33 by a coil 14 current of an auxiliary magnetic pole 13. In this case, magnetic lines of force near a main magnetic pole 30a are easily saturated and coarse, resulting that the vertical components are reduced. On the other hand, since the magnetic lines of force near a tip 30b where the main magnetic pole 30 is closer to the recording medium 11 pass through a low magnetic reluctance, the magnetic flux is concentrated and the vertical component is increased, allowing highly sense recording. Further the relation between a tilt angle theta and an output taking the recording current as a parameter is shown in figure.

Title: Piezoelectric actuator for optical alignment screw
Inventor: FURANSHISU ESU RUUKE
IPC: H02N2/00
Filed: 1995-02-27
Abstract: PURPOSE: To obtain an electromechanical actuator, more specifically, an actuator employing a piezoelectric element in order to turn a positioning shaft in relation to an optical element. CONSTITUTION: The piezoelectric actuator 50 comprises flange members 60, 61, and a flame secured to a base plate 85 through a flange 86. When the electric signal to a piezoelectric element 51 has such a polarity as the element 51 elongates to increase the amplitude of the electric signal being applied, relative movement takes place between the flange members 60, 61 in the longitudinal direction. Assuming no slip is present between the flange part and a shaft 80, the shaft 80 begins to turn. The piezoelectric element 51 contracts as the amplitude of electric signal being applied thereto decreases and longitudinal movement takes place between the flange parts 60, 61 in the opposite direction.  An electric signal rising or falling steeply due to inertial force of the shaft 80 induces a quick movement of the flange members 60, 61 which causes a slip between the flange part and the shaft 80.
