Title: Menu display device
Inventor: ASAHI TOSHIYUKI
IPC: G06F3/038
Filed: 1989-12-27
Abstract: PURPOSE:To improve the degree of freedom for the selection of display position of the related menus by providing a position deciding means which outputs a specific position within a selected item that is equal to the cursor position when selective operation is executed. CONSTITUTION:A menu bar display means 11 displays a menu bar in the area of a screen designated by an area storage means 12. When one of item groups forming a menu bar is selected by a selection means 14, a related menu designating means 17 decides a specific item stored in the means 12 where a cursor is kept in a selection state, then designates a related menu to be displayed. A position deciding means 15 refers to the means 12 to calculate the relative position of the cursor within a selected item. A position designating means 16 calculates a position where the related menu is displayed within a display enable area being recorded by a display area storage means 13 based on the output of the means 15. Thus it is possible to display the related menu in an area except those areas where the important information are displayed.

Title: Dynamic pressure bearing device and deflecting scanner
Inventor: ASAMI MASAYOSHI
IPC: F16C17/02
Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To avoid a gall at the time of decrease of rigidity of a bearing due to decrease of viscosity of oil by forming herringbone shaped dynamic pressure generating grooves which consist of a pair of the inclining groove parts on either one of a spindle and a sleeve engaged freely to rotate with each other, and by providing a circumferential groove communicating to inclining groove parts on a central part of the dynamic pressure generating grooves. SOLUTION: A spindle 2 for integratedly rotating with a rotating polygon mirror is rotatively fitted into a sleeve 3, and the sleeve 3 is fitted into a boss part of an outer cylinder. A space of 3 to 10 μm of a bearing is formed between the sleeve 3 and the spindle 2, and oil in the space flows by rotation of the spindle 2 to journal the spindle 2 in a non-contact state in a radial direction by the dynamic pressure. Two herringbone shaped dynamic pressure generating grooves 22b are formed on an outer circumferential surface (an outer diameter part) of the spindle 2.  A circumferential groove 31 is formed on a central part of the dynamic pressure generating grooves 22b, and a pair of inclining groove parts arranged above and below which are composed of the herringbone shaped dynamic pressure generating grooves 22b is formed by communicating to the central part intersected with the grooves in a V-shape, and thereby producing a stably annular groove. When the spindle 2 is sopped or rotated at a low speed, and an exothermic action of bearing is generated, the spindle 2 inclines, and then abrasive powders generated by contact with the sleeve 3 are collected in the central part by pumping actions of the grooves.

Abstract: PURPOSE:To increase the effective thickness of a channel layer while restraining the effect of a lattice mismatch by intervening a second channel layer wherein a composition is gradually changed so that the lattice mismatch causes no problem between a buffer layer and the channel layer. CONSTITUTION:Between a buffer layer 12 and a first channel layer 14 composed of superlattice structure semiconductor, intervenes a second channel layer 13 composed of the superlattice structure semiconductor wherein a composition is gradually changed so as to lattice-match the buffer layer 12 in a portion in contact with the buffer layer 12 and lattice-match the first channel layer 14 in a portion in contact with the first channel layer 14. Thus, even when a material which poorly lattice-matches the first channel layer 14 and the buffer layer 12 and from which only a small layer thickness can be taken for preventing a misfit dislocation from being generated is used for the first channel layer 14, by using the second channel layer 13, a channel layer as a whole can attain a large thickness while restraining the effect of a lattice mismatch.

Title: Propeller fan
Inventor: KAWASAKI HIROSHI
IPC: F04D29/38
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To maintain performance of a propeller fan and ensure operational reliability. SOLUTION: Plate thickness of a cover body 20 is so set that a part positioned to a front edge part 3a of a blade 3 is thinner than a part positioned to a rear edge part 3b. With such constitution, the rigidity of the cover body 20 is lower at the part positioned to the front edge part 38 of the blade 3 than at the part positioned to the rear edge part 3b, and in case of the blade 3 being flexure-deformed receiving bending force generated by centrifugal force in association with the operation of a propeller fan 1, the cover body 20 is deformed following the deformation of a blade body 10, and the flexural deformation of the blade body 10 is hardly impeded by the cover body 20. Separating force acting upon a joint part of the blade body 10 and cover body 20 is therefore reduced.  Since the plate thickness of the part, positioned to the rear edge part 3b of the blade 3, in the cover body 20 is set thick, the rigidity of the cover body 20 and in its turn, the rigidity of the whole blade 3 can be maintained excellent in spite of making the plate thickness of the part to the front edge part 3a thin.
