Title: Flaw detection of aluminium coated steel wire
Inventor: OGAWA MASAHIDE
IPC: G01N27/90
Filed: 1989-05-24
Abstract: PURPOSE:To perform the automatic flaw detection of an aluminum coated steel wire by selecting a distance and frequency so as not to react with steel in a normal part of aluminum. CONSTITUTION:A high frequency oscillation type proximity sensor 4 is allowed to approach an aluminum coated steel wire 1 to scan said wire 1 to perform flaw detection. When the detection distances of steel and aluminum are respectively set to SF3, SAl and the distance between the leading end part of said proximity sensor 4 and the surface of the steel 3 of the aluminum coated steel wire 1 and the distance between said leading end part and the surface of aluminum 2 of the wire 1 are respectively set to DFe, DAl, the high frequency oscillation type proximity sensor 4 is arranged so as to become SFe>=DFe, SAl<DAl and the frequency of the proximity sensor 1 is selected so that the penetration depth into aluminum 2 becomes equal to or less than the thickness of aluminum 2. Since output not responding to the steel wire 3 in the normal part of aluminum 2 but responding to the steel wire 3 in a flaw part 5 is obtained, flaw detection can be performed.

Title: Superconductive magnet unit
Inventor: SASAKI KATSUTOKI
IPC: H01L39/04
Filed: 1978-10-27
Abstract: PURPOSE:To enhance the cooling performance by preventing helium gas bubble from penetrating into the upper coil, a bubble barrier plate that spacedly covers the coil is installed at the middle upper half of the space between the faces of coil internal diameter side, side face and the container. CONSTITUTION:Liquid helium 3 is boiled to form bubbles by heat generated from the coil 1 and by heat penetrated from the outside of the container 2. The formed bubbles rise up through liquid helium in the duct as shown by the arrow 8. In the lower half of the coil 1, the formed bubbles move along the cylinder portion at the inner diameter side of the container 2 and rise up through the space between the bubble barrier plate 9 and the internal cylinder portion of the container. The bubbles then move along the barrier plate 9 in the upper half of the coil 1, rise along the side plate of the container 2 and flow up through the hole 2b to reach the pocket 2a. In this manner, bubble generated in the lower part is prevented from flowing into the upper portion of the coil 1 and results in reduced content of bubble and thus enhanced cooling performance.

Filed: 1995-05-30
Abstract: PURPOSE: To eliminate mask processing and to shorten the time for sequence arithmetic processing by instructing the requirement of initialization of a register at every bit by bit information. CONSTITUTION: The initialization signals *CLR0-CLR8 of the register 0 are generated by a select signal *CS3, write *WR and data *D0. The initialization signals are inputted to the reset input of a corresponding register by taking OR with the reset signal of the register. Concretely, data representing the requirement of initialization in which only D0 is set at 1 as setting the data of DO-D8 at 1, 0, 0,..., 0 on a universal CPU side is prepared, and the data is written on a register 10 for initialization of an LSI for calculation from the universal CPU side. In this way, the initialization signal in accordance with each bit of a correspond-register 20 of one byte is generated from a write signal on each bit out of one byte/eight bits of the register 10 for initialization. Therefore, the mask processing is omitted.

Filed: 1984-06-28
Abstract: PURPOSE:To form the titled photoelectromagnetic recording medium capable of double- sided recording with a simple recording and reproducing device by forming a magnetic thin film on both surfaces of a substrate consisting of a magnetic body. CONSTITUTION:A substrate 7 consists of a high-permeability magnetic body such as electromagnetic soft iron, and magnetic thin films 2 and 3 are formed respectively on both surfaces of the substrate 7 through heat-insulating layers 8 and 9.

The light energy concentrates on the part irradiated with a light beam during recording to increase the temp. of the part, and information is recorded as reverse magnetization. When the recording medium is put between a couple of magnets 5 and 6 whole N poles are opposed, the magnetic lines of flux emitted from the megnets 5 and 6 are introduced to the high-premeability substrate 7 while repelling respective counter magnetic lines of flux, and magnetic fields are impressed on the magnetic thin films 2 and 3 in the direction vertical to the film surface and opposite to each other. Consequently, the magnetic thin film 2 and 3 uniformly magnetized in the direction opposite to each other.
