Title: Westco type pump mechanism
Inventor: MINE KOICHI
IPC: F04D5/00
Filed: 1989-06-14
Abstract: PURPOSE:To improve the efficiency of pumping and lower a pump noise and increase the quantity of flow, by making a constitution so that the directions of an inlet hole and an outlet hole may become acute-angled against the flow directions of fluid at respective opposing flow passages. CONSTITUTION:At a pump portion 10, the directions of an inlet hole 25, a connection hole and an outlet hole 30 are formed so as to make the angle of an acute angle against opposing 1st and 2nd flow passages 15, 16. Fluid flows into the 1st flow passage 15 and the 2nd flow passage 16 in an acute angle shape, and also, flows out in an acute angle shape, so the degree of the conversion of flowing at the inlet hole 25, the connection hole and the outlet hole 30 becomes small. Thus, the occurrence of an eddy at the conversion portion of flowing is restrained, so the improvement of a pump efficiency, the lowering of a pump noise and the increase of a flow quantity can be attained.

Title: Rotary magnetic head device
Inventor: WATANABE YUKIO
IPC: G11B5/53
Filed: 1988-06-21
Abstract: PURPOSE:To reduce a cost and to prevent inconvenience from being generated in performance and manufacture by using a rotary erasing head to have an erasing gap width which is almost double of a conventional recording track width. CONSTITUTION:When an angle position on a cylinder drum 2 of a rotary magnetic head, which executes recording at first, is defined as reference 0 deg., a revolving magnetic head FE is fit to an angle position theta in the range of 180 deg.<=theta<=270 deg. to the rotational direction of the rotary magnetic head. Accordingly, since the rotary erasing head FE is always preceding to a recording head, the information of the track to be just recorded are prevented from being erased by the overlap of the rotary erasing head FE. Then, since the rotary erasing head FE to have the erasing gap width, which is almost double of the conventionally used recording track width, is used, it is not necessary to execute the design and manufacture of a new rotary erasing head. Thus, the production cost can be reduced.
