Title: Air intake device for engine
Inventor: KONDO MITSUNORI
IPC: F02B31/02
Filed: 1994-12-17
Abstract: PURPOSE: To throttle the passage-sectional area of an intake port to increase the flow velocity of intake, and prevent lowering of the flow late to ensure charging efficiency. CONSTITUTION: A definition plane for defining the sectional shape and sectional area of a port is tilted more toward a valve seat part forward in relation to the axis of the port to be connected to the axis of a valve by an axis connecting part with a small radius of curvature. By making the sectional area of the intake port on the definition plane about the same to restrict the sectional area perpendicular to the axis of the port, the flow velocity of intake is increased to intensify swirl. Then, the length of the axis of the port from a position of minimum sectional area up to the underside of a head 1, is set to 1.5 or less times the port-diameter D on the definition plane, and the inside diameter d0 of a valve seat part is enlarged in relation to the port-diameter D on the definition plane to enlarge a curtain area K.  In the case of double tangential ports, an enlarged-diameter part 7k for enlarging swirl component is provided in the umbrella-shaped part of an intake valve in relation to an intake port 4 on the front side in the direction of swirl.

Abstract: PROBLEM TO BE SOLVED: To form the digital images of low noise by performing constitution from the respective stages of performing correction relating to a nonlinear mapping function used in a preamplifier so as to generate digital signals from the digitized signals of distorted analog video signals. SOLUTION: Analog video signals are distorted or amplified beforehand in the preamplifier by the nonlinear mapping function (S704). The distorted analog video signals are processed for digitization including gain/offset adjustment (S706). An A/D converter receives the distorted analog video signals and generates the digitized signals of the distorted analog video signals by the first resolution of an 8-bit format for instance (S708). Then, the digital signals of the analog video signals are restored from the digitized signals of the distorted analog video signals and the digital signals are indicated by the second resolution of a 16-bit format for instance (S710).

IPC: H04N5/94
Filed: 1992-12-17
Abstract: PURPOSE:To deal sufficiently with a long burst error characteristic of magnetic recording while simplifying the constitution and reducing the cost of a magnetic recorder/player. CONSTITUTION:When a MUSE signal is subjected to FM recording, ternary PCM voice information of one field is stored in a voice PCM memory 6. A head HP dedicated for reproduction monitors the information recorded by a recording head HR and detects an address LD where dropout occurs thus reading out a corresponding backup data from the voice PCM memory 6. The backup data and the dropout address LD are recorded in a redundancy recording area of a magnetic tape by means of a head HB dedicated for backup recording. At the time of reproduction, the backup data is fetched previously and latched at a binary/ternary conversion memory section 21. When a MUSE reproduction signal is outputted externally, the dropout address LD is detected and the input to a dropout correction switch 26 is switched to the binary/ternary conversion memory section 21.

IPC: E04B1/64
Filed: 1996-12-18
Abstract: PROBLEM TO BE SOLVED: To stabilize the rust inhibiting effect over a long period and to improve operability and economy by using an aq. emulsion of styrenic resin, an aq. emulsion of asphalt and an inorg. powder as the main components of the inhibitor. SOLUTION: This rust inhibitor is composed essentially of a binder consisting of 5-25wt.% aq. styrenic resin emulsion as solid and 5-15wt.% aq. asphalt emulsion as solid and 60-90wt.% inorg. powder of an alkaline-earth carbonate not contg. a silicate as solid. Consequently, the inorg. powder is dispersed in the binder, and a coating film with the inorg. powder as an aggregate and bound with the styrenic resin and asphalt is formed. Since this coating film is chemically stable, the adverse effect such as a lowering of strength and an increase in water absorptivity is obviated over a long period. Further, since the amt. of the inorg. powder such as limestone powder is large, the flexibility and rust resistance of the coating film are improved, and the inhibitor is economically advantageous.
