Title: Kinematic mount for attenuation machine
Inventor: SIMONIAN STEPAN S
IPC: F16F15/00
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To obtain a kinematic mount where a new attenuation function is mounted, by arranging an attenuation means and a mechanical support means so that desirable performance characteristics can be provided. SOLUTION: A bending region 62 is formed by the notch of a bar stock used as a machine-supporting means. A spherical damper 46 is constituted of two partial shells 48 and 50 that are arranged concentrically. The partial shells 48 and 50 are mutually connected by a relatively soft layer 52 made of a viscoelastic (VEM) attenuation material being joined to the inner surface of the shell 48. The spherical damper 46 is deformed under a lauching load. Any bending operation at the center of a rotation operates the spherical damper 46 by causing the attenuation viscoelastic layer 52 to be subjected to shear deformation and hence scattering a vibration energy in the form of heat. By selecting an appropriate VEM, a considerable degree of attenuation can be achieved in a suspension vibration mode.

Title: Heat sensitive recording head
Inventor: TANNO KOTARO
IPC: B41J2/36
Filed: 1984-12-12
Abstract: PURPOSE:To enable different printing forms to be selected by an area gradation method to obtain multi-graduation by allowing continuity to be introduced only between desired electrodes using a positive characteristic thermistor which electric resistance value rapidly increases at higher than a certain temperature to a heating resistor. CONSTITUTION:The tips of plural signal electrodes 15, 16 are positioned along both edges of a positive characteristic thermister (PTC) which electric resistance value rapidly increases at higher than a certain temperature to a heating resistor 17. Then if a printing voltage is, for example, applied to signal electrodes 15c, 16a which allow continuity according to information, an electric current concentrates in the part 18 of the heating resistor 17 sandwiched between both electrodes and only said part is heated at high temperature. Thus many different heating dot forms can be selected. In addition, the area of the heating element can be varied by controlling the bulk width of a voltage to be applied and subsequently, super fine printing is performed in multi-gradation expression.

Abstract: PURPOSE:To read high density picture elements, which can be used in a high resolution television camera, by arranging horizontal charge transfer elements on both sides of a photoelectric conversion element group, providing a potential step in the one transfer state of vertical charge transfer element, and transferring signal charges upward and downward at every one column. CONSTITUTION:Pulses are applied to external clocks V1 and V2, and signal charges are transferred. At this time, the signals in odd-numbered rows are sent upward and the signal charge in even-numbered rows are sent downward owing to the potential step in a vertical charge transfer element 2. The signal charges are accumulated in storage gates. During this period, horizontal charge transfer elements 3 continue reading operations. During the horizontal fly-back time, the signal charges are transferred to the horizontal charge transfer elements 3 from the storage gates through transfer gates 9. At the end of the above described operation, the signal charges a1 in the odd-numbered columns are transferred to the upper horizontal charge transfer element 3; and the signal charges a2 in the even-numbered columns are sent to the lower horizontal charge transfer element 3. As a result, the density of the transfer stages of the horizon tal charge transfer elements 3 can be made 1/3 the conventional elements.

Title: Magnetic tape device and control method for the same
Inventor: UMEGAKI SUNAO
IPC: G11B15/00
Filed: 1990-09-28
Abstract: PURPOSE:To prevent the abrasion of a magnetic tape by changing the contact pressure between a tape cleaner and the magnetic tape. CONSTITUTION:The magnetic tape 1 travels in a right and left direction keeping the tension to a predetermined value, and the recording or the reproduction of data is executed by a magnetic head 2. At that time, the tape 1 is pressed against the cleaner 3 by the pressure determined according to positional relation between the tape cleaner 3 and a guide 4 and the tension of the tape 1. One end of the cleaner 3 is formed into a nut, and a lead screw 5 is coupled to this nut part. Accordingly, when a motor 6 is driven, the screw 5 is rotated, and the cleaner 3 is moved to the thickness direction of the tape 1. The control part of a tape device drives the motor 6 in response to a control signal so as to move the cleaner forward or backward. The contact pressure between the cleaner 3 and the tape 1 is increased by the forward movement of the cleaner, and is decreased by the backward movement of it. Thus, the dust removing ability can be raised without accelerating the abrasion of the magnetic tape.
