Title: Production of thin-film magnetic head
IPC: G11B5/31
Filed: 1992-03-31
Abstract: PURPOSE:To enhance accuracy by forming patterns for detecting a polishing depth in the gap forming part of a lower core and an upper core and controlling the polishing depth to a desired gap depth while observing the pattern width or measuring inductance. CONSTITUTION:The upper core 2 and the lower core are connected by a core juncture 7 and have a gap 8 to form a magnetic circuit. X0 denotes the position of the gap depth 0 and X1 the position of the prescribed gap depth. From X0 to X1 of the gap 8 is, therefore, an effective spacing for electromagnetic conversion. The prescribed gap depth is obtd. with high accuracy without generating a relative deviation between the gap depth zero 6 and the pattern for detection even if the sliding width of the head is narrowed to any width when the polishing is executed while the patterns for detection are observed from the sliding surface side. The control of the desired gap depth with the higher accuracy is possible if the polishing is executed while the inductance of the head is simultaneously measured.

Title: Digital filter
Inventor: MURAMATSU KUNIO
IPC: H03H17/02
Filed: 1987-03-30
Abstract: PURPOSE:To reduce a hardware quantity, by inverting the complement of 2 and the MSB(most significant bit) of straight binary, and enabling response to be performed to both inputs. CONSTITUTION:Data V'in can be obtained by controlling an exclusive OR gate E1 so that only the MSB of an input Vin is inverted when the input Vin is the straight binary, and no MSB of the input Vin is inverted when it is the complement of 2. At this time, when an input IN+ is selected by a selector S1, delay circuits DL1-DL4 are interposed in a signal path from the V'in to a delay signal D1, meanwhile, no delay is applied on a signal D2, therefore, a transfer function from the data V'in to an output Vout goes to 1+Z<-4>(Z1 expresses unit time delay). Similarly, when an input IN- is selected by the selector S1, since one inverter INV and the delay circuit DL4 are interposed in the signal path from the data V'in to the signal D1, the transfer function from the data V'in to the output Vout goes to 1-Z<-1>. Thus, since a digital filter can be used commonly for two different inputs, it is possible to reduce the hardware quantity.

Title: Nickel powder and conductive paste containing the powder
Inventor: ISHIKAWA HIROYUKI
IPC: B22F1/00
Filed: 1990-03-28
Abstract: PURPOSE:To achieve thickness and low resistance of an inner electrode layer by manufacturing such conductive paste as having Ni content of not less than 99.5wt.% and also as containing Ni powder of given properties, and using the paste. CONSTITUTION:The Ni content of Ni powder is set to not less than 99.5wt.%, and the area mean diameter thereof is set to the diameter of a globular body having a diameter of not less than 0.05 micrometer and of less than 1 micrometer. High reliability required for an electronic-part material can not be achieved sufficiently because Ni powder having Ni content of less than 99.5wt.% has bad effects upon the low resistance of an electrode or upon the properties of a dielectric. Also a grain having a area mean diameter of less than 0.05 micrometer is undesirable because it is easily condensed. And because of being in a globular shape, the desirable grains can take the form of a construction near their closest packing when an inner electrode is printed, and therefore a low resistance electrode having equal density and having few voids caused therein can be obtained after they are baked. A kind of electrode having its thinned inner-electrode layer, low resistance, and also reduction in the frequency of delamination, cracks and of the like all caused when conductive paste is baked can be obtained by manufacturing the conductive paste through the process of adding 2.5 pts.wt. of ethyl cellulose and 10 pts.wt. of terpineol respectively as a binder and a solvent to 100 pts.wt. of such globular powder like this and kneading the resultant material, and using the paste.

Filed: 1994-04-15
Abstract: PURPOSE:To obtain an optical recording medium enabled in recording and reproduction by visible laser beam by successively laminating a recording layer containing a tetraazaporphyrin dye, a reflecting layer and a protective layer on a transparent substrate. CONSTITUTION:A recording layer containing a tetraazaporphyrin dye represented by the formula I [wherein M is two hydrogen atoms or a divalent metal, L<1>, L<2>, L<3> and L<4> are respectively independently a group represented by either one of the formulae II, III (wherein A1, A2, A3, A4 and A5 are hydrogen, an alkyl group, an aryl group or halogen)] is provided on a transparent substrate. Further, a reflection layer and a protective layer are successively laminated to the recording layer to obtain a single palate type optical recording medium. Since the tetraazaporphyrin dye has almost no absorption in the vicinity of 780nm, when a dye having the max. absorption at 650-900nm is together used, a pref. result is obtained. As the reflection layer, a metal membrane composed of Al or Au is pref. and the protective layer is pref. composed of an ultraviolet curable resin or an electron beam curable resin.

Title: Separation type reverse stirling cycle refrigerator
Inventor: OSHIMA KEIJI
IPC: F25B9/00
Filed: 1990-03-27
Abstract: PURPOSE:To increase an inner wall area and improve radiation effect without increasing an inner capacity of a pipeline by connecting an expansion cylinder to a compression cylinder with a connection pipe so that the cylinders communicate with each other and setting the connection pipe so that it may be provided with a cross sectional shape where its inner diameter in the vertical direction is larger than the inner diameter in the horizontal direction. CONSTITUTION:A compressor 1 for an operating medium and an expander 2 for an operating medium communicate and are coupled with each other with a connection pipe 3. The inner diameter of the connection pipe 3 in the vertical direction is larger than the inner diameter in the horizontal direction. When the cross section shape is circular an identical in terms of the inner diameter both horizontally and vertically, the periphery length is the shortest in terms of its cross area. The greater the periphery length is, the greater the difference between the inner diameter in the vertical direction and the inner diameter in the horizontal direction is. Therefore, it is possible to increase the inner wall area of the pipe for the same pipe inner capacity. The connection pipe becomes less flexible for the cross section in the vertical direction. Therefore, when flexibility is needed, it is necessary to insert a flexible pipe fitting 31 comprising a circular pipe in the middle part. It is possible to increase the inner wall area of the pipe without increasing the inner capacity and improve the refrigeration efficiency of a refrigerator based on the improvement of radiation effect in terms of a radiation body 19B installed on the connection pipe.
