Title: Slight movement mechanism
Inventor: HATAMURA YOTARO
IPC: G05D3/00
Filed: 1988-11-15
Abstract: PURPOSE:To realize highly accurate displacement by securing a piezoelectric actuator with rigid bodies through cement composed of adhesive filled with resilient filler substantially linked therewith. CONSTITUTION:When voltage is applied onto a piezoelectric actuator 7 secured through cement 20 with protrusions 5, 6 in order to displace a rigid body 2, the piezoelectric actuator 7 elongates and the force caused by the elongation is transmitted sequentially to respective fillers 22 in adhesive 21 and the force functions finally between the protrusions 5, 6 thus displacing the rigid body 2. When voltage is removed from the piezoelectric actuator 7, the piezoelectric actuator 7 is reset immediately thus resetting the rigid body 2 and the protrusion 6 through the resiliency of flat boards 3, 4. By such an arrangement, residual vibration of a slight movement mechanism can be suppressed.

Title: Photographic halftone printing method for curved surface body
Inventor: NAKANO YOSHINORI
IPC: B41M1/40
Filed: 1987-11-13
Abstract: PURPOSE:To clearly reproduce colors of a photographic original with favorable fidelity, by reducing the quantities of cyan, magenta and yellow color inks to be superposedly applied to a surface of a curved surface body from a blanket in a printing press, completely removing one of the chromatic color inks used in the smallest quantity, and replacing by a black ink an ink quantity corresponding to gray of the quantities of the inks removed. CONSTITUTION:For example, a purple color expressed by using cyan, magenta, yellow and black inks in respective amounts of 5, 4, 3 and 1 parts can be expressed by reducing the quantities of the chromatic inks through changing the respective amounts into 4.8, 3, 0 and 2 parts and adding a black ink in a total amount of 4.2 parts. In this case, one of the chromatic ink, i.e., yellow ink is completely removed. Since the number of the chromatic inks is reduced, turbidity is not generated even when each of the inks is placed on a blanket 2, and images transferred from the blanket 2 onto a curved surface body 3 such as a can, form a clear image free of turbidity.

Title: Method for manufacturing magnetic head
Inventor: ONO HIROYUKI
IPC: B24B19/26
Filed: 1985-12-20
Abstract: PURPOSE:To absorb dispersion errors in packaging a magnetic head by adopting such a cylinder that the radius of a guide cylinder winding a wrapping tape is smaller than that of a drum cylinder for the tape guide of VTR. CONSTITUTION:A magnetic head 1 is attached integrally to a head base 3 at the edge part of a rotor 2 having a center O and is rotated at the predetermined speed by the rotor 2. While, a wrapping tape 4 winds through a guide pin 5 around a guide cylinder 6, abuts on the magnetic head 1 and grinds it. Here, the radius of the guide cylinder 6 is arranged to be smaller than that of a drum cylinder 8 for guiding VTR tape. As a result, when the magnetic head 1 is placed on VTR, the previously ground range is wider than that of the part to be touched by a magnetic tape, therefore, it is possible to absorb small dispersion errors caused in fixing the magnetic head 1 to VTR cylinder.
