Title: Device for shielding magnetic field in plane
Inventor: SMITH NEIL
IPC: G01R33/09
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To impart very high anisotropy to a shield rate along an orthogonal axis by the structure, wherein the loop-shaped rings of a soft magnetic material having high permeability are separated by the coaxial spacer rings of non- magnetic material partially containing air. SOLUTION: A basic structure 20 of an anistropic shield structure comprises a plurality of N pieces of loop-shaped rings 22 of soft magnetic material having high permeability. The rings 22 are mutually separated by the series of N-1 pieces of spacers 24 of ordinary non-magnetic material (containing air). When the above described structure is formed, for example, 14 pieces of the loop- shaped rings 22, whose permeability μ is in the order of 10<4> , are used in the structure 20, wherein the length L is about 1.3 inches and the diameter D is about 1 inch. The shield rate in the radial direction is in the order of several hundreds, and the shield rate in the axial direction is about 1.  For example, the suitable magnetic field is applied on the head part of a human body, and the fringe magnetic-field component is detected with the magnetic-field detecting system constituted by using a magnetoresistance sensor and the above described ring-shaped shield structure. Thus, foreign material such as a metal piece can be detected.

Title: Circuit for detecting collision of incoming and outgoing calls
Inventor: NAGATA KEIZO
IPC: H04Q3/42
Filed: 1986-08-20
Abstract: PURPOSE:To surely detect outgoing and incoming calls by connecting both a light emitting diode connected reversely a 1st diode and a 2nd diode that is connected in the reverse direction of said light emitting diode in parallel to a parallel circuit consisting the 1st diode and a 1st resistance only in an outgoing mode. CONSTITUTION:In the outgoing mode a contact point 12 is connected to a make side A by outputting a control signal, and a diode 10 and a resistance 11 are functioned. If a trunk line is not in an incoming state, a current is conducted through the following route: L1  a transformer 9 the diode 10 the contact point 12 a Zener diode 4 L2. However a current is not conducted to a light emitting diode 1a through said route, and a collision is not detected. The current conducted at that time is large enough to activate a station exchange. Afterwards, a contact point 6 is closed. By returning the contact point 12 to a brake side B, and opening/closing the contact point 6, a dial pulse is transmitted. An outgoing and incoming call collision detection means(CPU, for instance) detects the collision of incoming and outgoing calls, by judging from the fact that a potential at a point C changes to 0V from 5V. After the detection, a dead trunk line is searched to dial.

Filed: 1993-08-05
Abstract: PURPOSE:To reduce spring-back of a mask spherical peripheral part in warm press forming of an invar mask, and to improve mask deformation yield strength after forming is completed. CONSTITUTION:This die assembly is constituted so that an air blowout port 8 is provided in a peripheral part of a punch 1 of a warm press die, warm air or air of a room temperature is fed therefrom, and a temperature of a mask stock plate 6 and a forming mask can be controlled. At the time of overhanging the mask spherical surface, a temperature of the mask stock plate 6 is raised enough before the die and the mask stock plate 6 come into contact with each other. Also, in a process in which the forming mask is allowed to ascend and taken out from a bottom dead center at the time of forming the mask, it is taken out by blowing out air of a room temperature from the air blowout port 8 and after forced cooling. In such a way, recessed deformation caused by spring-back in the periphery of the spherical part peculiar to the invar mask can be suppressed, and also, wrinkle deformation generated at the time of taking out the forming mask from the die can be prevented.

Filed: 1988-08-04
Abstract: PURPOSE:To simplify a necessary processing for conversion by converting a floating point displaying form without the intermediary of the character data in which the data of a real number are displayed by the decimal system. CONSTITUTION:After the real number value by the floating number displaying of a first form expressed by the binary number of 32 bits, an index part and a mantissa part are respectively separately converted without the decimal character data, the conversion of the floating point displaying form from a first form to a second form is executed. Namely, the conversion of the index part is executed from the carry due to the remainder of the index part at the time of the function of 16<e>=(2<4>)<e>=2<4e>...(4) and the conversion from the binary to the sexadecimal of the mantissa part. Since for the mantissa part, the first form is displayed by the binary number and the second form is displayed by the sexadecimal number, the conversion is executed from the remainder of the index part when the conversion is executed from the binary to the sexadecimal together with a first form hidden bit. Thus, the conversion which keeps the accuracy of the real value before the conversion at the maximum can be performed.
