Title: Flow rate detecting device
Inventor: OZAKI YUKINORI
IPC: G01F1/05
Filed: 1983-06-21
Abstract: PURPOSE:To obtain an extremely small flow rate resistance, and also to obtain a small- sized and compact flow rate detecting device by setting a flow direction of a fluid to an axial-flow direction, and rotating a rotating body whose area is smaller than a sectional area of a flow path in a swirling flow by a swirling means. CONSTITUTION:A fluid to be detected which has flowed in from an inlet 24 side is brought to axial-flow swirling by flowing to the downstream along a circular arc blade 13 of a blade 11. As a result, a magnetic spherical body 18 turns round in the direction vertical to a direction of the flow by obtaining a dynamic force by the swirling flow. In this case, the magnetic spherical body 18 abuts on two points of a rotating surface 28 of a spherical body receiver 19 and a casing 12 and turns round. A revolving speed of a rotation of this magnetic spherical body 18 is proportional to a flow rate, therefore, the flow rate can be measured by measuring the revolving speed of this magnetic spherical body 18. Its means gives a magnetic field of a constant strength to a magneto-resistance element 21 by a permanent magnet 20, and a resistance variation of the magneto-resistance element 21 in case when the magnetic spherical body 18 has passed through this magnetic field is fetched as a pulse variation of voltage, and processed through a controlling circuit.

Title: Method for press-forming green compact and die press forming die
Inventor: SONODA TOMOAKI
IPC: B22F3/035
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To obtain a forming method in which a step is not attended on chamfered parts by pressurizing filled powder in the through hole of a die having tapered taper surface for chamfering and forming on the inside surface of the through hole of the die, between the end faces of a pair of outer punches and in end parts and which is surrounded with outer peripheral surfaces of a pair of inner punches whose end parts are mutually abutted. SOLUTION: The outer peripheral surfaces of the inner punches 3a, 3b are made into taper surfaces 34 and small diameter peripheral surfaces, chamfered parts 94, 94 on both sides and an inner peripheral surface 93 are formed in the hollow part of the green compact 9 and the steps are nor formed on the chamfered parts 94, 94. Because the inner punches 3a, 3b are divided into a pair of upper and lower parts, the green compact is easily released from the die by vertically separably pulling the inner punches 3a, 3b after molding. The endfaces 2a, 2b, 3a, 3b of the punches may be in flat shape, so the mechanical strength is larger and durable life is obtained. The step is not formed in the green compact 9, so grinding and polishing stages for removing the step after sintering are unnecessitated and finishing stage is simplified.

Title: Image retrieving device
Inventor: HIROSE MAKOTO
IPC: G06F17/30
Filed: 1989-05-08
Abstract: PURPOSE:To reduce the burden of a user by selecting a registered image which coincides with a condition image within an allowable range, based on the allowable range designated by an allowable range designating means and the degree of coincidence calculated by a coincidence degree calculating means. CONSTITUTION:At the time of executing a retrieval, a user inputs an allowable range by an allowable range designating means 1. A coincidence degree calculat ing means 2 derives a feature quantity of a retrieval condition image, compares successively this quantity with a feature quantity of each registered image, and calculates the degree of coincidence (or the degree of discrepancy). An allowable range control means 3 executes a control so that an image having a high degree of coincidence (or a low degree of discrepancy) calculated by the coincidence degree calculating means 2 remains behind as a coincidence image within the allowable range designated by the allowable range designating means 1. In such a way, an appropriate number of images can be shown to the user for any retrieval condition, and also, such a user's burden as many images are confirmed with eyes can be reduced.
