Title: Head supporting body in recording device
Inventor: SUGIYAMA YOSHIKI
IPC: G11B21/02
Filed: 1988-11-30
Abstract: PURPOSE:To lighten a storage device and to speed up the processing speed of the storage device by forming a head supporting body by means of a porous ceramic sintered body. CONSTITUTION:A carriage 5 is formed by the porous sintered body of silicon carbide. It is preferable that the porosity of the sintered body is 20-60%. The carriage 5 as the head supporting body is linearly reciprocation-moved between a position approximated to a magnetic disk 1 and a position detached from the magnetic disk 1 by a driving device incorporated with a coil on the carriage 5. Thus, the head supporting body is lightened and the driving force can be reduced. Rigidity is improved and a resonance frequency is improved. Thus, the extremely precise positioning of the head can accurately be performed and a access time can be shortened.

Title: Vacuum pump
Inventor: SAKAMOTO RYUICHI
IPC: F04D19/04
Filed: 1989-11-24
Abstract: PURPOSE:To accommodate a vacuum pump to usage in a wide-range from a medium vacuum area to a high vacuum area by making the screw angle of a deep groove located on an suction port side large and the screw angle of a shallow groove located on an exhaust port side small. CONSTITUTION:The inlet portion of a screw groove 4 located on a suction port 2 side is formed as a deep groove 41 which has the depth 1/3 or more the size of a rotary inner cylinder 5, and a space between the deep groove 41 and a shallow groove 42 on an exhaust port 3 side in the screw groove 4 is formed in such a shape as groove depth along a continuous curve. The screw angle of the deep groove 41 is made large and the screw angle of the shallow groove 42 is made small, to complete continuous angle-variation connection between the deep groove 41 and the shallow groove 42. In this way, as the screw angle of the screw groove at the inlet portion located on the suction port 2 side is made large, shift to large exhaust flow and large exhaust speed can be achieved. Also, the screw angle of the screw groove at an outlet portion located on the exhaust portion 3 side is made small and these inlet and outlet are connected to each other with continuous groove depth and screw angle, so that it is possible to ensure high compression ratio and exhaust performance in a medium vacuum area.

Abstract: PROBLEM TO BE SOLVED: To scan a significant volume of the heart intercostally and to realize observation in three-dimensional image system by operating an ultrasonic probe in an arc so as to scan the level that is oriented in a wedge or fan shaped volume. SOLUTION: A drive structure is connected to a probe frame 12 that connects to the ends of connecting rods 24 and 26 as it can turn. The rods 24 and 26 connect with an upper crankshaft 20 and a lower crankshaft 22 as they can turn. Each crankshaft has a drive shaft which is fixed to the holes 28 and 29. In the state (a), the probe frame 12 and a probe 100 incline against a standard line 50, and the scanning level 30 also does. As the crankshafts move clockwise around turning points of the holes 28 and 29, the inclination becomes smaller. While the probe 100 moves in the arc-shaped array, it is necessary for a scanner at the center of the hemispherical dome of lens 104 can pass along the scanning level inside the narrow opening of ribs.

Title: Picture recorder
Inventor: NISHIGAITO TAKAOMI
IPC: G03G15/16
Filed: 1988-12-05
Abstract: PURPOSE:To attain high picture recording with a comparatively small power and to simplify a recorder by reversely driving a recording medium and a transfer roller through a power transmitting means by the same motor. CONSTITUTION:By taking advantage of the fact that the direction of power to drive the recording medium 3 is reverse 4to the direction of power by which a transfer roller 91 carries a transfer material 10 at a fixed speed, the same driving source 70 drives the recording medium 3 and the transfer roller 91 through the power transmitting means 74 to reversely rotate them. The power to drive the recording medium 3 and the power by which the transfer roller 91 carries the transfer material 10 at a fixed speed act on the driving shaft of the driving source 70 as reverse load to cancel out. Consequently, the power that the driving source 70 requires becomes smaller, by which high picture quality recording is attainable under the simple structure.
