Title: Low dielectric constant multilayer ceramic board and manufacture thereof
Inventor: OGAWA KAZUNOBU
IPC: H05K3/46
Filed: 1990-07-31
Abstract: PURPOSE:To obtain a multilayered ceramic board which is high in bending strength, excellent in dimensional accuracy, and low in dielectric constant by a method wherein a ceramic layer of high density and a porous ceramic layer are specified in alumina content and porosity respectively, and the alumina content of the porous ceramic layer is larger than that of the ceramic layer of high density. CONSTITUTION:Ceramic material whose alumina content is 90-99.9% is used, and the main components of both dense ceramic layer slurry and porous ceramic layer slurry are alumina sol which makes water serve as dispersion medium. A dense ceramic layer and a porous ceramic layer are formed of the slurries concerned and dried up into green sheets, the green sheets are laminated and burned at a temperature range of 1200-1600 deg.C. At this point, a porous ceramic layer and a dense ceramic layer are so controlled as to be 20-60% and 0-5% in porosity respectively. By this setup, a porous ceramic layer of low dielectric constant is formed, which is reinforced by a dense ceramic layer, whereby a multilayered board high in bending strength and excellent in dimensional accuracy can be obtained.

Abstract: PURPOSE:To simplify the formation of a truck and to execute its forced steering to improve passing through performance along a curved road by devising a coupling structure between an axle and an interlockedly connecting member including an arm or the like related to the axle. CONSTITUTION:During the running of a car along a curved road, a car body and a truck frame move relatively as far as (d2) in a lateral direction, and further revolve as much as an angle of alpha2 round the axis of a center pin. A actuating shaft 51 turns into a state denoted with a virtual line 65 to cause operation links 47, 48 to produce the angular displacements of the second levers 40, 41 and of the first levers 28, 29, and the displacements of the first and the second links 18,19 and 26, 27 are therefore caused. In addition to that, wheels 10a, 10b are steered so that the extensions of the axis 66 of the axle 11 of the wheel 10a and of the axis 67 of the axle of the wheel 10b may pass through the center 60 of the curved road. Thus even when the radius of the curved road is small, the performance of a passing through along the curved road can be improved.

Title: Manufacture of steel tube
Inventor: MIYAMARU MASASHI
IPC: B21C37/08
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To manufacture a steel tube having good straightness by forming a steel sheet into a cylinder, fixing both ends of the cylinder in a state where bending distortion by which a seam side is made convex is imparted to the cylinder and welding the inside surface. SOLUTION: In a method for manufacturing steel tubes by forming the steel sheet into the cylinder 1 and, next, welding the seam 7 in the longitudinal direction of the cylinder 7 at least from the side of the inside surface, after fixing both ends of the cylinder 1 by fixing means 2 in the state where bending distortion by which the seam side is made convex is imparted to the cylinder 1, the inside surface is welded. When the inside surface is welded in the state where both ends are fixed, since bend (downward bend) such as the seam is made convex is pre-liminarily imparted, upward bend (the direction that the seam is made concave) which is finally generated by welding the inside surface and the downward bend which is preliminarily imparted are mutually canceled and the steel tube having reduced bend is obtained.

IPC: H03K5/08
Filed: 1981-12-17
Abstract: PURPOSE:To reduce offset voltage to reduce its dispersion by biasing the gates of switching MOSTRs in a chopper type comparator by a bootstrap type boosting circuit. CONSTITUTION:Boosting circuits 11a, 11b are connected to the gates of switching MOSTRs 3a, 3b constituting a chopper type comparator. The circuits 11a, 11b to be used are bootstrap type boosting circuits. Analog input voltage V1, comparison voltage V2 and a clock signal are applied to the terminal 1 of the TR3a, the terminal 2 of the TR3b and a terminal 13 respectively. The clock signal is applied to the boosting circuit 11b through an inverter 9. Consequently the gates of the TRs 3a, 3b are biased so as to have reversed phase each other and the change of charge proportional to voltage V1-V2 is generated in a capacitor 5. Thus a comparison output having no change of offset voltage is obtained from a terminal 8.

Abstract: PURPOSE:To prevent splashes of lubricating oil from being mixed in compressed gas and to prevent consumption of lubrication, by a method wherein a screw pump is mounted to a crank part at the upper end of a main shaft, and an oil extraction hole is formed in the bottom of the thrust bearing part of a frame. CONSTITUTION:When a main shaft 4 is started to rotate, after lubricating oil pumped up with the aid of a lubrication pump 4a lubricates a contact surface between a main shaft and a frame 12 and between a crank part 4b and a cylinder 1c, oil is fed to the upper surface of the crank part 4b.

Abstract: PURPOSE:To provide a material for magnetic head slider excellent in fittability to recording medium, thermal matching property with metallic magnetic film and bonding strength and satisfying various requirements such as abrasion resistance, precision machinability, high strength, density of texture, fitness to recording medium and lubricity. CONSTITUTION:The objective material for magnetic head slider contains CoO and NiO as principal components and incorporated with 0.1-7wt.% of zirconium oxide and/or hafnium oxide to the composition. The thermal expansion coefficient and the hardness of the material of the composition can be made to be comparable to those of a magnetic film structure and, accordingly, the material satisfies various requirements such as abrasion resistance, precision machinability, high strength, density of texture, fitness to recording medium and lubricity. Since the material has unprecedented excellent thermal matching property and the bonding strength of the material to a metallic magnetic thin film, it is most suitable for attaching to a thin-film magnetic head, coupled with the absence of reaction product and high uniformity which is unattainable by conventional material.
