Patent number: 8074695Abstract: An adhesive transfer device can reliably transfer by simple operation an adhesive onto a transfer target surface by either of spot-like transfer and linear transfer that are alternately selected. The adhesive transfer device has a supply reel (20) around which a transfer tape (1) having a backing material (2) provided with an adhesive (3) on one surface thereof is wound, a take-up reel (30) for taking up the transfer tape, and a transfer head (40) for transferring the adhesive onto the transfer target surface. The transfer head is pivotally supported at one end thereof and includes a first transfer section (45a) formed at a free end portion thereof and having a circular arc-shaped contact surface for mutual contact with the transfer target surface, a second transfer section (45b) having a flat transfer surface (45c) between the first transfer section and a pivot portion of the transfer head, and a spring member (46) for urging the free end portion of the transfer head toward the transfer target surface.Type: GrantFiled: May 7, 2008Date of Patent: December 13, 2011Assignee: Nichiban Co., Ltd.Inventors: Nobuyuki Sekiya, Masatsugu Yamaguchi, Masashi Tanaka, Takashi Kawakami

Patent number: 5358576Abstract: In amorphous materials including at least one iron-transition metal of Fe, Co, and Ni, and at least one metalloid of B, C, Si, and P, excellent magnetic characteristics can be provided subject to the condition that 0.5 to 10 atomic % of the above-described iron-transition metals are substituted by Mn. In addition, when the amorphous material partially substituted with Mn as described above is further comprised of at least one element selected from Groups IIIa, IVa, Va, and VIa in the periodic table, the crystallization temperature is considerably raised.Type: GrantFiled: June 6, 1980Date of Patent: October 25, 1994Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Harufumi Senno, Hiroshi Sakakima, Masatsugu Yamaguchi, Eiichi Hirota

Patent number: 4288260Abstract: A method of heat treatments of amorphous alloy ribbons comprises the sequential steps of; grinding amorphous alloy ribbon continuously fed at a predetermined speed (V) selectively varied in the range of 1 cm/sec.ltoreq.V.ltoreq.50 cm/sec, to uniformly finish the ribbon, and successively, heat-treating the ribbon with its surface contacting a stationary or rotating heating body having a surface temperature (T) defined in the range of (T.sub.cry -200.degree. C.).ltoreq.V.ltoreq.(T.sub.cry +50.degree. C.), where T.sub.cry is a crystallization point temperature of the alloy, to uniformly enhance the magnetic properties of the ribbon, and to remove the specific curlings inherently caused by so-called splat cooling manufacturing method, without causing any developments of brittleness of the ribbon mentioned above.Type: GrantFiled: March 26, 1980Date of Patent: September 8, 1981Assignee: Matsushita Electric Industrial Co.

Patent number: 4041437Abstract: This invention provides a humidity sensor having a negative coefficient of resistivity for relative humidity, which comprises 99.99 to 10 mole percent of iron oxide (Fe.sub.2 O.sub.3) and 0.01 to 90 mole percent of at least one member selected from alkali metal oxides, which are lithium oxide (Li.sub.2 O), sodium oxide (Na.sub.2 O), potassium oxide (K.sub.2 O) and cesium oxide (Cs.sub.2 O). The amount of the alkali metal oxide in the sensor is preferably 0.01 to 25 mole percent. This sensor is advantageous because it can accurately detect the changes in humidity and it has a long, stable life.Type: GrantFiled: December 24, 1975Date of Patent: August 9, 1977Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Mikio Matsuura, Nobuji Nishi, Masatsugu Yamaguchi, Michio Matsuoka, Takeshi Masuyama
