Title: Forming method for mask for ion etching
Inventor: TAKAHASHI YOSHIO
IPC: H01L21/302
Filed: 1985-10-08
Abstract: PURPOSE:To obtain a metal film mask for ion etching which ensures an excellent pattern precision, by a method wherein a moderately-sloping layer for sloping a stepped portion moderately is applied by coating on a thin film layer in which the stepped portion is formed by the indented surface of a lower pattern layer. CONSTITUTION:An insulating layer 34 is provided on a first conductor pattern layer 33 which is patterned on a substrate 31 with an insulating layer 34 interposed between them, and a conductor layer 36 is connected thereon. After a moderately-sloping layer 37 forming of a resin material and provided for sloping a stepped portion moderately is applied by coating on the conductor layer 36 in which the stepped portion is formed by the indented surface of the pattern layer 33, a metal film 38 is connected thereon. The metal film 38 is patterned with a resist pattern 39 used as a mask. In succession, the moderately-sloping layer 37 except for the part thereof in a region wherein the patterned metal film is formed is removed selectively by etching, and a metal film mask 40 for ion etching is formed on the conductor layer 36. The conductor layer 36 is ion-etched with the mask 40 being used, and thereby a section conductor pattern layer 41 can be obtained with excellent precision.

Title: Polarized electromagnet
Inventor: NAGAMOTO MITSUKI
IPC: H01F7/14
Filed: 1986-09-24
Abstract: PURPOSE:To improve magnetic efficiency by allowing a pair of armatures to form surface contact with the intermediate magnetic pole section and either of the side magnetic pole sections due to the elastic deformation of a flexible permanent magnet. CONSTITUTION:When a coil 2 is electrically energized from one side, an armature block 5 is rotated and the free ends 6a, 6a of armatures 6, 6 reverse from one side to the other side, respectively contacting with an intermediate magnetic pole section 1a and a magnetic pole section 1c of one side. At this moment, forces P1, P2 are respectively applied to a flexible permanent magnet 4 placed between the armatures 6, 6 with points C and D as the points of application, and the magnet 4 contracts due to its own elastic force, whereby the free ends 6a, 6a of the armatures 6, 6 are brought into surface-contact with the intermediate magnetic pole section 1a of a yoke 1 and the magnetic pole section 1c of one side. With this, contacting with the corner sections of the armatures as before will be eliminated, and thus the magnetic reluctance is lowered, enabling a polarized electromagnet of a good magnetic efficiency to be obtained.

Title: Measuring method for concentration of dry-cleaning agent and container used therefor
Inventor: NAKAHARA NORIO
IPC: D06F43/08
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To relatively easily measure the concentration of a cleaning agent in dry-cleaning solvent by putting into a cylindrical container a washing liquid obtained by addition of the cleaning agent to the dry-cleaning solvent, and comparing the amount of emulsification of the added water with the amount of emulsification in a standard liquid. SOLUTION: A concentration scale part which shows a proper range of emulsification by a standard fluid, with 0 at its center, is formed at a constricted part 10c formed in an area halfway between upper and lower large-diameter parts 10a , 10b . In this case, a washing fluid S1 (S2 ) obtained by addition of a cleaning agent to a dry-cleaning solvent is injected up to the zero position of the concentration scale part so that the lower (upper) limit concentration of a dry-cleaning agent is attained, after that water W is injected by an about equal amount from above. Therefore, the fluid S1 (S2 ) is replaced by the water W with a part of the water W being emulsified by the cleaning agent in the fluid S1 (S2 ) to form an emulsified layer N1 (N2 ). With the layer as a range L1 (L2 ), the area between L1 and L2 is set as the proper emulsification range.  Next, an emulsification test of a washing agent to be measured is performed by similar procedures, and whether the concentration of the agent is within or out of a specified range is determined based on whether or not the range of the emulsified layer is within the proper range.
