Title: Thick-film hybrid integrated circuit board
Inventor: KINOSHITA MASAKI
IPC: H01L21/98
Filed: 1985-04-22
Abstract: PURPOSE:To prevent peeling due to molten solder even after a heat history by a method wherein an Ag-Pd thick-film conductive layer is formed on an insulating substrate, another conductive layer of a simple metal is formed to partially cover the alloy layer, so that the simple metal may be diffused into solder, in a process of soldering leads to the simple-metal layer, for the elevation of the melting point of said solder. CONSTITUTION:On an insulating substrate 1, an alloy thick-film conductive layer 2 is formed. A suspension of Ag mixed with some metal powder as binder is applied to an installation land 22 in the alloy thick-film conductive layer 2. The applied suspension after baking is converted into an Ag thick film for the formation of a simple Ag conductive layer 8, whereto leads 7 are attached by means of solder 9. The solder 9 should be a low-melting solder composed of Sn, Pb, Ag, etc. and the heating for the soldering of the leads 7 to the conductive layer 8 and the heating for the soldering of a transistor 3 to the installation land 22 are accomplished, simultaneously, at a low temperature. During the heating for the low-temperature soldering, silver is diffused from the conductive layer 8 into the solder 9. Accordingly, with the percentage increased of silver, the solder 9 now has a higher melting point.

IPC: G01L9/00
Filed: 1983-05-18
Abstract: PURPOSE:To accurately detect the internal pressure of a cylinder at every cylinder, by providing a member for detecting the wall displacement of a combustion chamber caused by the internal pressure of the cylinder and a signal take-out member for taking out the displacement as a signal between the wall of the combustion chamber and the outer shell wall thereof while adequately detecting the displacement proportional to the internal pressure of the cylinder. CONSTITUTION:A cylinder internal pressure detecting sensor 10 is mounted to the outer shell 1A of a cylinder head 1 at every cylinder and the pressure sensitive part 11 of the sensor 10 is brought into contact with the protruded seat 2B of the head part wall 2A of a combustion chamber of which the upper surface is flatly formed. The head part wall 2A of the combustion chamber or the cylinder liner wall 4A of a cylinder block 4 generates displacement outwardly corresponding to the change in the internal pressure of the cylinder, that is, displacement is generated toward the side of a cooling water passage 2 in the head part wall 2A while toward the side of a jacket 7 in the liner wall 4A. In this case, the pressure sensitive part 11 of the sensor 10 receives displacement pressure to give strain to a piezoelectric element and generated charge is taken out by a lead wire 12.

Title: Manufacture for magnetic head
Inventor: IWASAKI JUN
IPC: G11B5/39
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To eliminate a special rust preventive by using a paraffin-based hydrocarbon as a solvent of a grinding fluid used in a process of grinding a magnetic head having a thin film element by a grinding wheel. SOLUTION: In order to cool a grinding wheel and an object to be ground at a grinding work point, to maintain a lubricity between the two and to disperse/eliminate cut dust generated by the grinding, a grinding fluid is jetted and supplied from nozzles arranged in the periphery of the grinding work point. The grinding fluid used here has a paraffin-based hydrocarbon as a solvent which maintains a fluid state at the grinding work point where a temperature increases. Since water is not used as the grinding fluid, the fear of corroding a material of a low corrosion resistance such as FeMn, Cu or the like used in GMR elements is eliminated. The used paraffin-based hydrocarbon is one that includes water as less as possible. Since the paraffin-based hydrocarbon itself has a lubricity, a special lubricant is not necessary to add.

Title: Control method of injection molding and its controller
Inventor: TAKENO KAZUNORI
IPC: B29K21/00
Filed: 1992-03-09
Abstract: PURPOSE:To improve both stability in weight and stability in shape of a molding product when a viscoelastic material having a complicated viscoelastic behavior characteristic such as rubber or the like is injection molded. CONSTITUTION:Total displacement Z of a plunger 5 is supposed to be composed by adding displacement Z1 applied to viscoelastic behavior of a molded material to displacement Z2 applied to injection from a nozzle 3. The displacement Z1 applied to viscoelastic compression behavior is obtained by expressing viscoelasticity of the molding material in an injection material 2 by a viscoelastic pattern. Displacement Z2 applied to injection from the nozzle is obtained by subtracting the displacement Z1 applied to viscoelastijc compression behavior from the actual total displacement Z of the plunger. An actual injected flow rate (g) is calculated of the molding material to be injected from the nozzle is calculated by the displacement Z2, and a filling amount of the molding material filled in a metal mold 1 is controlled based on the injected flow rate (g). An aimed injection flow rate pattern is realized by monitoring indirectly the injected flow rate without carrying out real time measurement of the injected flow rate.

IPC: A01C17/00
Filed: 1994-04-25
Abstract: PURPOSE:To provide a fertilizer distributor furnished with a fertilizer-stirring apparatus free from the intrusion of fertilizer into a shaft-supporting surface of a bearing which supports the front end of a spreading shaft and placed in a fertilizer tank. CONSTITUTION:A bearing 15 is placed in the bottom of a tank in a protruded manner from it and the boss 22a of a stirring member 22 has a cylinder-shaped part 22ab covering the upper side of the bearing 15. Since the shaft-supporting surface where a spreading shaft 7 and the bearing 15 fit with each other is communicating to the tank through a gap (g) formed by the cylinder-shaped part 22ab and the bearing 15 fitting it, the length of the labyrinth reaching the shaft-supporting surface is become long. Further, the intruding direction of the fertilizer is upward at the gap (g). Accordingly, the gap (g) is resistant to the squeezing of the fertilizer, the shaft-supporting surface is free from the intrusion of fertilizer and the rusting of the surface is prevented.

Filed: 1986-04-15
Abstract: PURPOSE:To improve the ability of manufacture and assembling operation and to improve detection accuracy by allowing the distance between a body of rotation and a transducing means to be varied. CONSTITUTION:Brackets 56 and 58 are provided projecting on a sensor substrate 36 in its upper end center and on both lower part sides, and long-sized holes 60 and 62 are bored therein extending to or away from a magnet ring 24.

In this case, the screws 64 are loosened to move to or away from the magnet ring 24. Consequently, when components are assembled in manufacture, they are assembled temporarily at proper positions, and then can be adjusted finely by being moved again unless a desired detection output is obtained at the time of a test in a trailing stage; and the separation distance can be adjusted so as to obtain the desired detection output. Thus, the detection accuracy and operation efficiency are improved.

Abstract: PURPOSE:To prevent an image formation reference position from deviating and to accurately maintain optical axis accuracy by providing a roll which rolls on a guide member for moving a moving table in the direction of an optical axis at an end part of a guide rod. CONSTITUTION:On the opposite sides of a 1st moving table 30 from bearings 30A, rolls 33 are fitted to tips inserted into the bearings through the shaft parts of guide rods 15. The rolls 33 are positioned on the same plane with the axis positions of the guide rod 21 on the 1st moving table 30 and guide rods 15 on a 2nd moving table 31. The 1st moving table 30 is therefore suspended and supported by a rail 23 through the guide rod 21 on the 2nd moving table 31 and by the guide rod 21 on the side of the 1st moving table 30. Namely, the rigidity of the guide rod 15 which supports the 2nd moving table 31 slidably is set large to prevent the 1st moving table 30 from being loaded directly with the weight of respective components including the 1st moving table 30, thereby eliminating inclination due to the deflection of the coupling part.

That is, the slope of the head track to the core thickness is taken as θ 2  and the slope of the track to the gap depth is taken as θ 3 . Thus, a number of heads can be machined at the same time easily.
