Title: Coil
Inventor: KUWABARA TAKASHI
IPC: H01F41/04
Filed: 1988-06-25
Abstract: PURPOSE:To obtain an arbitrary turn ratio simply by changing an electrode- printing mask and to simultaneously form an electrode for board mounting use by a method wherein a minute hole is made in a core material, a conductor is installed in the hole and an upper-part conductor and a lower-part conductor are connected. CONSTITUTION:This coil is formed of printed conductors 1 for board mounting use, lower-part printed conductors 2, through holes 3, upper-part printed conductors 4, a ferrite 5 and protective glass sheets 6. B-B', C-C'...H-H' are conductors constituted on the rear of the ferrite 5; B'-C, C'-D...bG'-H are conductors constituted on the surface of the ferrite 5. The conductors on the ferrite 5 are connected by the through holes 3. By this setup, six turns are wound on a ferrite core between the conductors, and a coil can be formed. Since the coil is constituted by directly printing the conductors on the ferrite 5, an insulated electric wire is not required and lands for board mounting use are printed and constituted simultaneously; accordingly, a pedestral is not required.

Title: Apparatus for cleaning up washing liquid for electrolytic cleaning
Inventor: SEKIGUCHI KATSUMASA
IPC: C25F7/00
Filed: 1983-08-30
Abstract: PURPOSE:To improve the efficiency of a system and to reduce cost by passing the washing liquid for a metallic strip to a multi-stage heat exchanger to cool said liquid then stirring the liquid to flocculate the same, subjecting the flocculated liquid to vacuum dehydration and passing the treating liquid to the preceding heat exchanger. CONSTITUTION:The cleaning liquid for metallic strip in an electrolytic circulating tank 20 is passed through the 1st heat exchanger 2 and is cooled to about 40 deg.C, then said liquid is fed to the 2nd heat exchanger 3 using a refrigerant and is cooled to about 20 deg.C. The liquid is fed to a stirring tank 4 where the liquid is stirred at a low speed to grow flocs of soap. The flocculated liquid is dehydrated with a vacuum dehydrator 5 and the filtered cake is removed from a rotary filter cloth body 5a by a scraper 7. The cleaned up liquid is put into a receiving tank 13 and is fed forcibly into the 1st heat exchanger 2 where the liquid is subjected to a heat exchange with the untreated liquid and thereafter the liquid is returned to the E.C. tank 20. The continuous and exact removal of the soap-content and iron-content in the washing liquid is thus made possible by the relatively low speed operation.

Title: Writing utensil
Inventor: FUKUDA MASAO
IPC: B43K8/02
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To control blurred handwriting or writing inability through connecting an ink flow between a pen point and an ink relay core over time by forming a collar part on the pen point side tip part of the ink relay core and arranging an elastic repulsion part between the collar part and the writing utensil body to bring the tip of the ink relay core into contact with a pen point rear end under pressure. SOLUTION: A collar part 3a which is of a large diameter on a tip part is formed on an ink relay core 3. In addition, a thin wall piece 2d with elastic repulsion is formed at a corresponding position to the rear stage 3b of the collar part 3a of the ink relay core 3, so that the rear stage 3b of the ink relay core 3 is urged in a pen point direction. Consequently, even when each of members is deviated out of its arranged position, resulting from the mon- uniformity of the dimensions of parts such as the ink relay core 3 and the pen point 5, the dimensional deviation is absorbed to bring the tip of the ink relay core 3 into contact with the rear end of the pen point 5. Thus it is possible to keep a state in which the flow of the ink is connected ideal and avoid a state in which an urging force is brought to bear upon the entirety of the ink relay core 3.

Title: Reagent for immunoassay
Inventor: SUZUKI MASUMI
IPC: G01N33/58
Filed: 1987-06-26
Abstract: PURPOSE:To improve measurement sensitivity by housing a soln. of nitro PAPS into an endoplasmic reticulum having a membrane labeled by an antigen or antibody. CONSTITUTION:This reagent has preferably the endoplasmic reticulum which has the membrane labeled with the antigen or antibody and is housed internally with the soln. of the nitro PAPS and a liquid in which this endoplasmic reticulum is dispersed and contains the metal ions capable of forming a colorable complex between the same and the nitro PAPS. The metal ions include Ni(II), Co(III), Fe(II), Zn(II), Cu(II), etc. The nitro PAPS has high water solubility, can be dissolved at several hundreds millimol or above in 1l buffer soln. and is capable of increasing the concn. of the chelate agent housed in the endoplasmic reticulum. The complex forming reaction between the nitro PAPS and the metal ions is sensitive and the coefft. of molecular absorption is as high as order of 10<5>. Since the absorption wavelength of this complex exists mostly at >=600nm, the errors by the absorption of extraneous matter are decreased. The measurement sensitivity is thus improved.

Title: Method for recovering high-purity gallium
Inventor: NISHIYAMA YUTAKA
IPC: C22B58/00
Filed: 1987-06-26
Abstract: PURPOSE:To easily recover high-purity gallium in a short time, by subjecting gallium-containing scrap to chlorination and distillation separation to prepare crude gallium chloride, reducing the above aqueous solution with metal, and then applying distillation to the above under reduced pressure. CONSTITUTION:Gallium-containing scrap such as gallium-arsenic and gallium- phosphorus, is crushed and charged into a dissolution vessel, where gallium and other element are chlorinated by means of chlorine gas. After or simultaneously with the chlorination, distillation separation is applied, by which AsCl3, PCl3, etc., are removed and crude gallium chloride composed principally of GaCl3 and GaCl2 is obtained. Further, rechlorination treatment is applied to convert GaCl3 into GaCl2 with lower boiling point, which is distilled and rectified into refined gallium chloride. Subsequently, this aqueous solution of refined gallium chloride is reduced by metal (zinc, etc.) and then subjected to vacuum refining at about 200-1,000 deg.C under a pressure of about 0.01-10Torr to undergo impurity removal. By this method, high-purity metallic gallium can be recovered and used as semiconductor material.

The eccentricity of this elliptic face is set to 1/n (n is the refractive index of materials constituting a lenticular lens 7b). A part 8 of an elliptic face having the same eccentricity as the lenticular face is formed on the output surface facing to the lenticular face 5, and the output surface is formed to a lenticular face also. Consequently, red and blue input lights are outputted as parallel beams from the face 8, and thus, white is not colored even at the sight of a screen from sideway.
