Title: Rotary head assembly
Inventor: NAKA HIROYUKI
IPC: G11B15/61
Filed: 1982-12-14
Abstract: PURPOSE:To float a tape stably and to improve input/output characteristics of a signal by forming a spiral groove in one of facing surfaces of a rotation part, providing a pressure interference area in its discharge port, and absorbing variation in discharge pressure. CONSTITUTION:The spiral groove 11, a land 12, and a common groove g1 are formed on the rotation member 2. When a spiral groove 9 is formed on the rotation member 2, discharge pressure observed at a fixed point on a rotary head assembly varies with the number of spiral grooves. When the common groove is provided in the discharge port, the space at this part serves as a sort of surge tank against surging pressure to obtain damper effect to pressure variation. Therefore, the pressure at the radial end part of the rotation member applied with the discharge pressure enters a uniform static pressure state. Consequently, the tape 1 floats over the rotary head assembly by an extremely slight extent completely except at a magnetic head 5 and the tape lead 10 on a fixed cylinder 3.

Abstract: PURPOSE:To reduce the energy required in printing and to obtain gradation properties by forming a pair of electrodes on the same wall surface of an ink flow passage so as to be adjacent to each other at a microgap and making the effective length of the discharge gap between electrodes becoming a discharge gap part larger than the length of the wall surface of the ink flow passage of an electrode arranging part. CONSTITUTION:A pair of electrodes 31, 32 are arranged in the vicinity of the nozzle orifice 1 of an ink flow passage 2. Both electrodes 31, 32 are arranged on the same plane forming a part of the wall surface of the flow passage so as to be adjacent to each other at a fine interval and constituted so as to be capable of selectively applying voltage. Discharge is generated in the gap between the electrodes 31, 32 but the length having a uniform gap along the electrodes is called a discharge gap effective length. The shape of the gap between the electrodes is bent and the discharge gap effective length (l) being a length of L-L' is larger than the wall surface length D of the flow passage. By this constitution, a region where discharge can be generated is increased and stable discharge is obtained by increasing the generation chance of discharge and the generation of discharge is made possible even when abrasion is advanced in a part of the electrodes and the life of the electrodes can be made long necessarily and sufficiently.

Title: Chimney
Inventor: IIDA YASUHIKO
IPC: E04H12/28
Filed: 1998-08-04
Abstract: PROBLEM TO BE SOLVED: To improve a function by providing plural vertical louvers the inner surface side air passage areas of which are smaller than outer surface side air passage areas at the same height as an inner cylinder of an outer cylinder top part. SOLUTION: A chimney 1 is constituted by providing a permeable wall 5 surrounding an outer periphery of an inner cylinder 2 and consisting of plural vertical louvers 4 roughly at the same height as the inner cylinder 2 at a top part of an outer cylinder 3 surrounding plural numbers of the inside cylinder 2. Thereafter, a horizontal cross section shape of the louver 4 is made trapezoidal where side length of an outer surface side 3a of the outer cylinder 3 is smaller than side length of an inner surface side 3b or triangle where a top point is directed to the outer surface side 3a.  As a passage between the adjacent louvers 4 becomes narrow toward the inside of the outer cylinder 3 when air moving by cross wind in the neighbourhood of the wall 5 enters the outer cylinder 3 through the louvers 4, the air passing through the louvers 4 is compressed, suddenly expands in the outer cylinder 3, comes to easily flow above the outer cylinder 3 where pressure is low, the air blowing by from the louver 4 in the downstream of the outer cylinder 3 decreases. Consequently, it is possible to restrain occurrence of down wash and to prevent contamination of the outer cylinder.

Title: Substitute bone substance based on natural bone
Inventor: HAINTSU MITSUTERUMAIYAA
IPC: A61F2/28
Filed: 1984-10-19
Abstract: The bone substitute material on the base of natural bone is rendered completely free of albumin and antigen by premaceration, pyrolization and sintering and its frame work consists of only the natural mineral structure of the natural bone. In the process of production of this bone substitute material the bone pieces are submitted to a pretreatment with warm water for removing of the soft parts, subsequently takes place a dealbumination by means of a solution of 10 to 30% H2O2 in a shaking machine and a degreasing with ether. The bone pieces treated in this way are subsequently submitted to a combustion in a stove at 400 DEG  C. to 1500 DEG  C. and then to a sintering. This bone substitute material which may exist in the shape of the bone part to be replaced forms a form stable matrix for the bone regeneration in which only pure "mineral bone" is present so that no immunogen reactions can take place. The process which includes combustion and sintering is considerably shorter than known processes.
