At the same time, the smaller diameter part 29b faces to the cam follower 35. The arm 31 is inclined at the center of an inclination shaft 33 and the resistance heat generating part 52a is pressed into contact with the printing face of the card 58 for printing. Accordingly, the printing face is held in tight contact with the resistance heat generating part without being curved.

Patent JP-H08194907-A (JP)
Title: Magnetic head
Inventor: ARIGA EIKICHI
IPC: G11B5/187
Filed: 1995-01-20
Abstract: PURPOSE: To obtain the excellent tape touch in a short time even if the base thickness of a tape is changed by a method wherein the widths of core protrusions near a magnetic gap are gradually narrowed toward both the ends of the protrusions in a tape sliding direction to have the tape touch excellent. CONSTITUTION: The widths of core protrusions 2c1 and 2d1 are W near a magnetic gap 2a and, the closer to both the ends of the protrusions in a tape sliding direction, i.e., the direction of an arrow (c), the narrower the widths. At both the ends of the core protrusions 2c1 and 2d1 , the widths are as narrow as W4. A pressure applied to a unit area of a tape at the core protrusions 2c1 and 2d1 of which a tape sliding surface is composed is smaller than a pressure applied to a unit area of a tape at a slider protrusion 42d which is the other sliding surface. This is because a width W1 which is the summation of the respective lengths of the core protrusions 2c1 and 2d1 is larger than the width W2 of the slider protrusion 42d.  Therefore, the protrusion 42d is worn much but the protrusions 2c1 and 2d1 are worn little and hence the protrusions 2c1 and 2d1 are made to protrude more and their widths are gradually narrowed toward both the ends of the sliding surface, so that the tape touch can be improved.

Abstract: PURPOSE:To prevent a memory address speed from lowering and to greatly increase a memory density by partially and selectively adsorbing chemical materials on a substrate to form arbitrary rugged patterns formed by the chemi cal material adsorbed parts and non-adsorbed parts. CONSTITUTION:The substrate 4 is constituted of a base body 3 and a memory carrier holding layer 2. The memory carrier holding layer 2 is the layer to adsorb or desorb the chemical materials to be used as the memory carriers 1. The surface of the memory carrier holding layer 2 is required to have precise flatness. One molecule of the chemical materials or the aggregates thereof are used as the memory carriers 1. The memory density is increased and the memory capacity is increased in this way. Since the memory density is high, there is no need for increasing the entire part of the memory and the decrease in the memory address speed is prevented.

Abstract: PURPOSE:To downsize an apparatus and reduce the number of parts and further to obtain a large displacement by forming a strain element into a belt and then by helically winding the strain element to form a strain element bar. CONSTITUTION:A piezoelectric actuator 1 is equipped with a hollow coil spring 3 and the surface of the coil spring 3 is wound by a beltlike piezoelectric element 5. The beltlike piezoelectric element 5 is helically wound on the surface of a hollow round bar constituting the coil spring 3 over the total length of the hollow round bar. Then, when an electric field is applied to the beltlike piezoelectric element 5, the piezoelectric element 5 is deformed in the longitudinal direction.

As a result. a torsion moment T is generated in the cross section of the coil spring 3 and the hollow round bar is wound into a coil so that the coil spring 3 generates a displacement 6 in the axial direction at the time of receiving the torsion moment T.
