Title: Laminar flow keeping type high-lift device
Inventor: AMANO KANICHI
IPC: B64C9/24
Filed: 1993-11-12
Abstract: PURPOSE:To facilitate a change between a cruising condition and a high-lift condition by providing either of a frontal line slat or a leading-edge Krueger flap formed on the front of a wing leading-edge part made into an adhesive streamline laminar flow type profile when developing operation is made to a high-lift flight condition from a cruising flight condition. CONSTITUTION:A leading-edge profile outer plate 1 and a Krueger flap 6 form the front part lower surface of a main wing in a cruising condition, the leading- edge profile outer plate 1 forms a leading-edge having a large radius, that is, an adhesive streamline laminar flow type profile, and the Krueger flap 6 is moved to the front to form the Krueger flap in a high-lift condition. The development into a high-lift condition actually increases the leading-edge radius of the main-wing leading-edge part 5, consequently the path of a flow along a leading edge is lengthened to increase the movement quantity of the flow per unit time, that is, a flow velocity, to increase a velocity gradient. As a result, a boundary layer is thinned to become an adhesive streamline laminar flow to maintain a laminar flow over a broad region from the leading-edge lower part to the upper surface of the wing, generating a very large lift compared with a conventional turbulent type.

Title: Integration circuit
Inventor: NAKA HIDEYUKI
IPC: G06G7/184
Filed: 1989-10-30
Abstract: PURPOSE:To obtain excellent distortion characteristics by comparing the center potential of an output voltage generated on both ends of an integration capacitor with a prescribed bias potential and controlling current flowing into a pair of current circuits based upon the compared result. CONSTITUTION:The integration capacitor CI2 is connected between both the output terminals (collectors of transistors(TRs) Q3, Q4) of a cascade type voltage/current conversion amplifier to differentially extract the output voltage. Thereby, distortion due to the non-linearity of the output characteristics of the TRs Q3, Q4 can be removed. On the other hand, the center potential of the output voltage is compared with the prescribed bias voltage VBI to control the positive pole side current of the amplifier. Thereby, the center potential of the output voltage is stabilized. Consequently, excellent distortion characteristics can be obtained independently of the non-linearity of the output characteristics of the TRs Q3, Q4.

IPC: G11B7/26
Filed: 1987-11-10
Abstract: PURPOSE:To decrease the noise components in a reproduction signal and to lower a signal error rate by forming an optical recording layer into two-layer constitution and executing recording and reproduction of signals by utilizing the pits formed in the 1st layer. CONSTITUTION:The 1st layer 12 which consists of the sublimatable material exhibiting transparency to a reproducing light beam is formed on a transparent substrate 11 and the 2nd layer 13 which induces melting and evaporation when subjected to irradiation of the light beam is formed on the 1st layer 12. Information is recorded by projecting the light beam to the 2nd layer 13. The 2nd layer 13 is thereafter etched away in plasma and further, a reproducing beam reflecting film 14 consisting of Au, Ag, Cu, Al, etc., is stuck thereto. Namely, the part irradiated with the light beam is heated by the heat generated in the 2nd recording layer 13 and the material sublimimates in the 1st recording layer 12 consisting of the sublimatable material and, therefore, recesses (pits) are formed. The same reflectivity as the reflectivity of a reproduction-only optical disk such as compact disk is thereby obtd. and the signal quality is improved. The noise components are thus decreased and the error of the reproduction signal is lowered.

Title: Joining body of ceramic member and metal member
Inventor: MIYAKE MASAYA
IPC: B23K20/00
Filed: 1994-10-24
Abstract: PURPOSE:To inexpensively obtain a joining body having a stably high bond strength by joining a ceramic member comprising Si3N4 or SiC to a metal member while laying a soft metal plate and a cemented carbide plate having specific compositions between the members. CONSTITUTION:In joining a ceramic member comprising Si3N4 or SiC to a metal member, two kinds of plates of a soft metal plate of Al, Cu, Al-Si, Ti or Nb and a thin cemented carbide plate are laid from the side of the ceramic member between both the members. Consequently, heat is applied during the joining, since difference in thermal expansion between the ceramic member and the cemented carbide of the joining layer is small, stress produced by heating between the joining layer of the ceramic and the cemented carbide can be reduced. Therefore, after the joining, the ceramic has slight fear of separation even by reheating. Preferably the surface of the ceramic member is sputtered, provided with an active metal layer such as Ti and a soft metal plate is laid on the active metal layer.
