Title: Base for hair-dressing agent
Inventor: UCHIYAMA YUUJIROU
IPC: A61Q5/06

CONSTITUTION:The hair-dressing base agent is produced by polymerizing monomers consisting of a combination of 3-30wt.% of a monomer of the formula I (R<1> is H, methyl or CH2COOH; R<2> is H, methyl or COOH), 5-60wt.% of a monomer of the formula II (R<3> is H or methyl; R<4> is alkylene), 3-40wt.% of a monomer of the formula III (R<5> is alkylene; R<6> and R<7> are H or alkyl; X is NH or O) and 1-60wt.% of a monomer selected from acrylic monomer of the formula IV (R<8> is alkyl) and vinyl acetate. The base has excellent water- solubility as well as moisture resistance and is suitably usable for aqueous hair-blowing agent. The base agent is easily removable by shampooing and exhibits high set-retaining power. It has sufficient characteristics to impart hair with excellent luster, softness, etc.

Title: Acoustic amplifier
Inventor: FUKUI YUKIO
IPC: H03G3/20
Filed: 1979-04-06
Abstract: PURPOSE:To make it possible to reproduce music with fidelity regardless of the temperature change of a loudspeaker by controlling power supplied to the loudspeaker by detecting the power. CONSTITUTION:Power supplied to loudspeaker 4 is detected by power detecting circuit 6 and input to control input terminal 9 of gain control circuit 8 by way of integrating circuit 7, so that as the input of terminal 9 increases, the gain will also increase. Then since the voice coil temperature of loudspeaker 4 is in proportion to the integral value of the power supplied to loudspeaker 4, the gain of gain control circuit 8 is incresed as the temperature of the voice coil rises. Therefore, a signal input to input terminal 1 is amplified and then input to pre-amplifier 2, and the output of main amplifier 3 also increases. Thus, a current proportional to the input signal flows even when loudspeaker 4 varies in impedance due to a temperature rise, so that music can be reproduced with fidelity.

Filed: 1995-03-01
Abstract: PURPOSE: To alleviate the temperature change of a sensing unit by providing low heat transfer means for increasing the thermal capacity of the unit by a high thermal capacity sealing structure and decreasing the heat transfer amount at the outside of the structure. CONSTITUTION: A magnetic sensing unit 1 having a magnetostrictive material 2, a permanent magnet 3, optical fiber coils 4, 5 and optical couplers 6, 7 is inserted into the half-split copper sphere having large thermal capacity, and embedded in the copper sphere 8. The sphere 8 is hung in a vacuum vessel 9 by a hanging string 10 made of nylon having low thermal conductivity. If the temperature of an external environment is changed, the thermal capacity introduced to or output from the unit 1 is the heat radiating transfer between the inner wall of the vessel 9 and the surface of the sphere 8, and the thermal conductions of string 10 and the fiber passed through the vessel 9, and the amount is reduced as compared with the case that the unit 1 is directly exposed with the atmosphere. Since it is embedded in the sphere 8 having large thermal capacity, the temperature change is delayed.

Title: Electrode wire for discharge machining
Inventor: AOYAMA MASAYOSHI
IPC: B23H7/08
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To improve the inferior workability caused by Zn, reduce the occurrence of breakage or scars at the time of drawing, and improve workability and the machining speed by using a brass alloy of a Cu-Zn-B composition containing a proper quantity of boron. SOLUTION: B of 0.03-0.3wt.% is added to a Cu-Zn alloy having the Zn concentration of 40-50wt.%. This Cu-Zn-B alloy is charcoal cover-dissolved by a high-frequency heating vertical casting machine, and a wire is continuously manufactured. The wire is drawn by a die at the draft of 15%, then it is heated for 30min at 800 deg.C in the Ar atmosphere. This machining is repeated to manufacture a drawn wire having the prescribed outer diameter. When the added concentration of B is 0.03wt.% or below, breakage occurs at the time of drawing. When it exceeds 0.3wt.%, voids are easily generated in the wire at the time of drawing. When B is added and contained, crystal refinement is progressed, the drawing property in the post-process is improved, and the machining speed can be improved when the Zn concentration exceeds 40wt.%.
