Title: Manufacture of permanent magnet
Inventor: SAKAI ISAO
IPC: H01F1/047
Filed: 1989-12-05
Abstract: PURPOSE:To obtain a permanent magnet characterized by high magnetic flux density, excellent square-shapedness and excellent oxidation resistance furthermore without necessarily requiring rare earth metal and B by heat-treating an alloy comprising Zr of specified atomic % and the substantial amount of Co for the remaining part. CONSTITUTION:An alloy comprising Zr of 20atom.% and the substantial amount of Co for the remaining part is heat-treated at 300-1,000 deg.C. For example, at first Zr and Co are compounded at the rare of 15% Zr and 85% Co in atomic fraction. Arc melting is performed by using a water-cooled copper boat in an Ar atmosphere. Then, the obtained alloy is cooled at a super quench speed by a single-roll method using a copper roll having the diameter of 300mm at a speed of 40m/sec in the Ar atmosphere. Thus the ribbon-shaped alloy which has the average grain diameter of 0.07mum in main phase and is cooled at the super quick speed is manufactured. Then the super quench ribbon-shaped alloy described above is heat-treated in vacuum at 700 deg.C for 10 minutes, and the ribbon-shaped permanent magnet is manufactured. Or the alloy is crushed and the alloy powder is obtained. Epoxy resin is added and mixed. Thereafter, the powder is compressed and molded, and curing is performed. Thus the bond magnet is manufactured.

Title: Substrate for thermal head
Inventor: NONOYAMA OSAMU
IPC: B41J2/335
Filed: 1987-12-14
Abstract: PURPOSE:To form a narrow and thin glaze layer having flatness, by forming the surface of a substrate, to which at least the glaze layer must be formed, so that alumina content is set to specific wt.% or more and surface roughness (Ra) is set to a specific value or less. CONSTITUTION:A substrate 1 has alumina (Al2O3) having large heat conductivity as a base composition and consists of alumina and glass flux (e.g., SiO2) as a sintering aid. The content of alumina is set to 98wt.% or more. When said content is 98wt.% or less, a glaze component locally flows in the formation of a glaze layer to become an undulated state because of the non-uniform dispersion of alumina and flux and the glaze layer 2 having a smooth surface is not obtained. Further, the glaze component and the flux component get intimate well with each other and the glaze component becomes easy to flow and the partial glaze layer 2 having a small radius of curvature can not be formed. The surface roughness (Ra) of the substrate must be 0.15mum or less. When the surface roughness is larger than 0.15mum, glaze flow becomes non-uniform linearity and is deteriorated.

Title: Dynamic range compressor for input signal
Inventor: FUKUNAGA KOICHIRO
IPC: H03H17/02
Filed: 1992-10-30
Abstract: PURPOSE:To arbitrarily change the dynamic range of the input signal with simple and small amount of hardware constitution by computing the power level of the input signal by a detection circuit, computing the control information constant for the output by a control constant circuit, multiplying the input signal by the control information constant, and computing it to the prescribed amplification degree. CONSTITUTION:When an input signal D5 is inputted to a detection circuit 3, a power signal DP is produced. The calculated power signal DP is inputted to a control constant arithmetic circuit 4. In the circuit 4, a value '1' of a constnat circuit is subtracted from the power signal DP to be supplied and a signal (DP-1) to be outputted is supplied to a multiplier 4c. Further the squared signal (DP-1)<2> is supplied to a multiplier 4d and further squared (DP-1)<4> can be obtained. From a multiplier 4d at the final stage, a control constant K can be obtained as the arithmetic result of the control constant arithmetic circuit 4 and is inputted to a compression arithmetic processing circuit 2. Thus, the power level is increased for the low level input, and is reduced for the high level input.

Filed: 1992-11-25
Abstract: PURPOSE:To prolong the life of bellows and improve the operation availability factor of a reactor by separating the inflow area of a driving fluid driving a piston and the arranged area of the vacuum sealing bellows, and indirectly pressurizing the bellows. CONSTITUTION:When a reactor core internal structure is to be fixed to a vacuum vessel, a liquid inlet 14 is pressurized, the inner tube 6a and outer tube 6b of the piston rod of a piston 6 are integrally driven in the direction to shrink vacuum sealing bellows 11, and a cotter 7 is driven into the insertion hole of the reactor core internal structure. The driving liquid 12 leaked to the bellows 11 side is discharged from an atmosphere release port 16. When the reactor core internal structure is to be removed from the vacuum vessel, a liquid inlet 15 is pressurized, the cotter 7 is extracted, and the liquid 12 leaked to the bellows 11 side is discharged from the atmosphere release port 16. The pressure force of the liquid 12 is not directly applied to the bellows 11, and only the differential pressure between the vacuum region and the atmosphere is applied. The life of the bellows 11 repeatedly expanded and shrunk is largely extended, and it can contribute to the improvement of the operation availability factor of a reactor.

Said movement of squeegee 3 regulates the thickness of a resin layer on the resin layer 93 to the thickness (h) and accelerates the flattening of resin. At that time, laser beam is emitted in the given pattern from a laser beam source 12 to photoset the resin layer on the resin forming layer 93.
