Title: Tank for dissolving magnetic metal powder
Inventor: TANOGUCHI ICHIROU
IPC: B01F27/71
Filed: 1995-02-27
Abstract: PURPOSE: To supply a dissolving liq. having a low content of an undissolved magnetic metal powder to be supplied to a filter to the filter by dissolving a magnetic metal powder in the dissolving liq. in a dissolution tank and leaving the undissolved magnetic metal powder in the dissolution tank as long as possible. CONSTITUTION: When the dissolution of a magnetic metal powder is finished in a dissolution tank 1, the agitation of a dissolving liq. 9 by an impeller 5 is stopped, and a permanent magnet 2 is moved and brought close to the bottom face and the side face outside a furnace. The undissolved magnetic metal powder remaining in the liq. 9 is attracted and held on the bottom face and side face. The dissolving liq. reduced in the undissolved magnetic metal powder concn. is sent to a filter 3 and filtered. Consequently, since the dissolving liq. having a low content of undissolved magnetic metal powder is supplied to the filter in this way, the liq. permeability of the filter is increased, and the frequency of backwashing and change of filter cloths is reduced.

Title: Punch cutter edge
Inventor: NAKAGAWA HIKOYOSHI
IPC: B23D27/02
Filed: 1982-03-10
Abstract: PURPOSE:To cut metal sheet coated with resin film with fine sharpness and make its cut surface completely smooth by a method in which a recessed part is formed at the inside of at least either a stationary edge or a punching edge, and the width of a push-surface is made small. CONSTITUTION:A recessed part 39 is formed at the inside of a stationary edge 37. As the width of a push-surface 38 becomes small due to the recessed part 39 at the inside of the stationary edge, the cutting force exerted on a coating film 44 by way of the stationary edge 37 accompained by punching force is concentrated onto the push surface 38 with small width. Consequently, due to the small width of said push surface, resin layer is perfectly compressed, and punching force acts on a metal sheet with the minimum thickness of the resin layer. Accordingly, the metal sheet is cut with fine sharpness by the direct  action of the punching force without bent.

Title: Optical communication equipment
Inventor: ISHIHARA TOMOHIRO
IPC: H04L12/28
Filed: 1987-02-20
Abstract: PURPOSE:To make the optical reception level in a network terminator constant independently of the distance from each terminal equipment by resetting a signal converted into an electric signal at each network connection device to a preset level again and outputting the result. CONSTITUTION:One input electric signal of a signal processing means 600 of a network connection device is subjected to time division multiplex so as not to collide with the electric signal of the output of a photoelectric conversion means 500 being other input. The multiplexed signal is converted into an optical signal by an electrooptic conversion means 400 and inputted to the network terminator via an optical transmission line 800. In this case, an photoelectric conversion means 500 in terminal connection equipments 900-1-900-n discriminates 0, 1 signal converted into an electric signal and resets the signal 0, 1 to a prescribed level and outputs the result. Thus, in the network terminator, the signal of a prescribed level is received independently of the distance from each terminal equipment in the network terminator.

Then, the control part 13 impresses a driving signal to a third lens supporting bar 4, a Y directional driving coil 8, and a fourth lens supporting bar 5 for exciting the lens holding part 1 in the Y direction by the driving force of a Y-directional driving coil 8.  At that time, the electric resistance values of the first lens supporting bar 2, the X-directional driving coil 7, and the third lens supporting bar 4 are measured by the resistance measuring part 16. Then, when the electric resistance values are temporarily increased to a set value (threshold) or more, failure due to defective soldering (nonstandardized) is judged.

Title: Universal attachment
Inventor: MATSUBARA YASURO
IPC: B23Q3/12
Filed: 1994-02-14
Abstract: PURPOSE:To easily and quickly set an accurate and small angle by establishing a relative space between angle setting elements for a base end body case and a forward end body case. CONSTITUTION:The space X of each angle setting element 56 for a base end body case 12 and the space Y of each angle setting element 58 for a forward end body case 14 are established, so as to satisfy the expression where (n) is a natural number equal to or above 2. In other words, a difference between X and Y can be expressed as Y-X=Y-[(n-1)/n]Y=Y/n. An angle fixing means 60 is provided at the matching position of both angle setting elements 56 and 58 for establishing the angles of both cases 12 and 14. An angle, therefore, can be indexed for every angle having a smaller space Y/n than the spaces X and Y actually used at a machining process. Provided that X=10 degrees, Y=1 degree and n=11, for example, Y/n becomes equal to 1. That is, an angle can be indexed at a smaller angular space than the actually applied angle spaces of 10 and 11 degrees.

Abstract: PURPOSE:To enable only a precipitation echo to be accurately displayed by using the data in an area from which the ground echo that can not be completely removed even by the use of a Moving Target Indicator (MTI) filter is not present. CONSTITUTION:Elevation angle judging means 6a judges whether the present elevation angle of an antenna is the one corresponding to an area wherein the ground clutter that can not be completely removed even by a MTI filter is present. Signal analyzing means 6b performs a signal analysis by using the collected data at an elevation angle other than the one at which the ground clutter is present. Data replacing means 6c replaces the data in the area wherein the ground clutter is present with the data after the signal analysis. The ground clutter that can not be completely removed even by the MTI filter is completely removed by using the data of the elevation angle different from that including the ground clutter.
