Filed: 1986-12-10
Abstract: PURPOSE:To reduce the size and weight of an acceleration detector by composing the detector of a magnetic spherical body floated in the ferromagnetic liquid charged in an enclosed container made of a nonmagnetic body, detection coils, exciting coils, and a magnet couple for holding the magnetic spherical body in the center of the enclosed container. CONSTITUTION:The ferromagnetic liquid 2 is charged in the enclosed container 1 made of the nonmagnetic body and the magnetic spherical body 3 is suspended in the ferromagnetic liquid 2. The magnetic spherical body 3 is held normally at the center position in the enclosed container 2 through the operation of the magnetic forces of magnets 5a and 5b and the operation of buoyancy from the ferromagnetic liquid 2. Then acceleration operates to right in parallel to a center axis X-X line, and then the magnetic spherical body 3 is displaced to left in the opposite direction from the direction of the acceleration. Consequently, said two detection coils generate a differential output voltage and the value of the acceleration is detected from the difference output voltage while the direction of the acceleration is detected from the polarity. Consequently, the structure is simplified and the size and weight are reducible.

Title: Production of ceramics substrate
Inventor: BANDAI HARUFUMI
IPC: H05K1/03
Filed: 1988-11-21
Abstract: PURPOSE:To obtain the ceramics substrate which is inexpensive and has smooth surfaces by alternately laminating and press-welding ceramics green sheets which are opposite in the warpage directions at the time of calcination in a specific form and integrally calcining the sheets. CONSTITUTION:The ceramics green sheet 10' which constitutes the ceramics substrate when calcined is formed by laminating and press-welding two sheets of the ceramics green sheets 12, 14. The sheets 12, 14 are so disposed that the film-contact surfaces of the sheets at the time of the formation of the sheets are positioned on both the outside surfaces of the ceramics substrate after calcination. The ceramics green sheets 12, 14 are laminated is such a manner that the warping direction occurring in the packing density of the ceramics particle is made to the opposite. The warping and curving stresses of the respective ceramics green sheets 12, 14 are, therefore, offset or relieved and suppressed when the sheets 12, 14 are superposed on the substrate and are press-welded by, for example, a cold isostatic pressurization method. The deformation and warpage over the entire part of the ceramic green body 10 are obviated. The stage for correcting the warpage is, therefore, not executed.

IPC: C23C2/00
Filed: 1990-10-31
Abstract: PURPOSE:To effectively prevent the rolling up of dross due to a plating metal flow by providing an inclined face part opposed to the sink roll and steel strip traveling line at an appropriate distance from the roll and line to a plating metal flow straightening structure. CONSTITUTION:The first face part 41 confronting with a melting part 6, the second face part 42 opposed to the sink roll 7 and steel strip traveling line at an appropriate distance from the roll and line and the third face part 43 opposed to the inclined bottom of a plating part 5 are formed on a plating metal flow straightening structure 4 arranged in the plating bath 1. Since the cross section of the plating metal passage between the second face part 42 and the steel strip 8 is smaller than that in the melting part 6, the flow rate of the plating metal in the plating part 5 is limited. Consequently, the linear flow velocity of the plating metal in the melting part 6 is made lower than the flow velocity in the plating part 5, and the dross contained in the plating metal introduced into the melting part 6 and having a relatively large grain diameter is effectively settled on the bath bottom and removed.
