Title: Vertical shaft type sealless agitator
Inventor: ASA TAKESHI
IPC: B01F7/16
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To make foreign matters produced in a seal part, a bearing, or the like provided on a driving shaft for driving an agitating tool not enter an agitating vessel as an impurity. SOLUTION: An central hole 18a and an upward inner cylinder 18 are installed in the center of the bottom part of a vessel part 3a to pass a driving shaft 17 through them, and a taper part 17a of the lower end of the driving shaft 17 is supported by a thrust bearing 8. A central hole 19a and a downward inner cylinder 19 installed in the center of a cover 13 of the vessel part 3a surrounds the upper part of the driving shaft 17. When the driving shaft 17 is rotated at high speed through a joint 20, the rotating shaft 17 stands by itself by gyro-action, and liquid to be treated is agitated while raising it in a hollow cylinder along the inner peripheral surface of a vessel 10. Since there is not a seal part or a bearing in the upper part of the vessel part 3a, there is no source of foreign matter and foreign matter does not fall.  When an elevation/lowering device 6 is operated to lower a support frame 4 and disengage the joint 20 to disengage the vessel part 3a from an engaging part 7, the agitating part 3 can be separated from the frame and the driving source.

Title: Magnetic disk device
Inventor: HIROSE YOSHIMI
IPC: G11B21/02
Filed: 1984-05-24
Abstract: PURPOSE:To correct the relative displacement between a servo head and data head due to temperature variation, by inserting a spacer having a linear expansion coefficient which is different from that of an arm holder into part of the head arm pressing surface of the arm holder. CONSTITUTION:A spacer 11 having a linear expansion coefficient which is different from that of an arm holder 6 is inserted at the left side of the head arm pressing surface of the arm holder 6. Since the spacer 11 is inserted into the pressing surface of a servo head arm 22, a servo head arm 32 makes motion different from a data head 31 does. In short, when the coefficient of linear expansion of the spacer 11 is smaller than that of the arm holder 6, the servo head 32 moves in X-direction. This movement can be changed in size and direction when the material of the spacer 11 is changed. Moreover, when the thickness of the spacer 11 is changed, the size of the movement can also be changed. When this spacer 11 is used, the relative displacement between the servo head 32 and data head 31 caused by temperature variation can be corrected.

Title: Fading simulator
Inventor: OZAKI TAKAYUKI
IPC: H04B17/00
Filed: 1983-06-13
Abstract: PURPOSE:To evaluate satisfactorily the actuation of a space diversity receiver by varying the phase and the amplitude of two path and obtaining equivalently the fading in a reception mode of the space diversity. CONSTITUTION:The output of a modulation signal generator MD is divided into two parts by a hybrid circuit H1. At the same time the signal applied to a delay line DL is set correspondent to the signal of a space diversity system, and this output signal is divided into two parts by a hybrid H4. When these divided signals pass through phase shifters PH1 and PH2 and attenuators AT1 and AT2, a signal underwent the variation of its phase and amplitude is obtained. Then the 1st and 2nd signals D1 and D2 are synthesized independently by synthesizing hybrids H2 and H3 respectively. Thus a reflected wave and a direct wave are synthesized, and also a signal underwent the fading is obtained. This state can be varied while grasping two systems, and therefore it is possible to obtain a signal suited for evaluation of actuation of a space diversity receiver.

Abstract: PROBLEM TO BE SOLVED: To perform the smooth cutting of fish body into three pieces of fillet without having troubles caused by clogging of fish. SOLUTION: This apparatus is composed of a transferring means, two pairs of main round rotary blades 5a, 5b, 6a, 6b, and a pair of supplementary round rotary blades 7a, 7b. The transferring means holds the center of the middle rib of a heat-cut fish body F1 by a pair of clamps from the both sides of the direction crossing to the dorso-ventral direction and transfers the fish body in the longitudinal direction of the fish body. The two pairs of main round rotary blades 5a, 5b, 6a, 6b are placed in the pathway where the head-cut fish body F1 is transferred so that each of the pairs of round rotary blades has a space through which the middle rib of the transferred fish body F1 can pass. The pairs of the main round rotary blades are placed at both sides of the position where the middle rib passes.  Thus, the two pairs of the main round rotary blades 5a, 5b, 6a, 6b cut the transferred heat-cut fish body from both the dorsal side and the ventral side toward the vicinity of the middle rib. The pair of supplementary round rotary blades 7a, 7b are placed on the downstream side of the transferring direction of the head-cut fish body from the position where the both pairs of the main round rotary blades 5a, 5b, 6a, 6b are approaching to each other, and cuts and separates the middle rib from the head-cut fish body. Further, each pair of the main round rotary blades are placed so that blades are closed at the transferring pathway side of the head-cut fish and widened at the departing sides from the transferring pathway.  The supplementary round rotary blades 7a, 7b are placed in such a manner that they partly enter between the two pairs of the main round rotary blades 5a, 5b, 6a, 6b, but not interfere them, and intrude into the pathway of the head-cut fish.

Title: Single-spot plural-droplet printing system
Inventor: ELLSON RICHARD N
IPC: B41J2/21
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a single-spot plural-droplet printing system which consumes only specified small peak powder required for operation. SOLUTION: The spot cycle, of each of plural printing heads, which consists of 1-N operating periods is asynchronized by shifting the phase of the spot cycles from each other. For example, the spot cycles of single printing heads 204, 205 are started and the spot cycle of another printing head is started after a non-multiple of N of droplets. Consequently, the spot cycles of two printing heads are asynchronized. Thus the peak average power consumption of an optical operating period of the spot cycle of an acoustic printing system is reduced by asynchronizing the spot cycle of the printing head, and therefore, the demand peak power of the printing head is saved.
