Title: Inter-frame prediction coding system
Inventor: KUWATA KOJI
IPC: H04N19/51
Filed: 1992-06-11
Abstract: PURPOSE:To obtain a reproduced picture with stable quality for all blocks by setting a new independent frame between frames when a difference between frames of preceding and succeeding independent frames exceeds a prescribed threshold level. CONSTITUTION:A moving picture signal of various formats is inputted by an input device 1 and a processing unit 2 converts the signal into a required format by a coder 3. The coder 3 reduces a data quantity to generate a bit stream without deteriorating the inputted moving picture. A 3n-th order independent frame from the beginning is fetched by the difference device and the difference between the n-th independent frame and the (n+1)th independent frame is calculated and when the value is larger than a prescribed threshold level, a frame located between the two compared frames is set to a new independent frame. Thus, the frequency of the independent frame is high for a period subject to a rapid change and an independent frame with a large prediction error is eliminated, then a reproduced picture with high picture quality is obtained.

Title: Ventilating fan for duct
Inventor: TAKUSHIMA WATARU
IPC: F24F7/06
Filed: 1984-07-23
Abstract: PURPOSE:To simplify duct work and prevent the chattering sound of a shutter by forming a duct connecting joint incorporating a shutter therein to a specified configuration. CONSTITUTION:The duct connecting joint 6 which is tapered so as to be fitted into the duct 112, is attached to a duct mounting member 4 closely attached to the main body 1 of the ventilating fan so as to surround the opening 5 of the duct mounting member. The shutter 8 is attached to cut-ups 7 in the duct connecting joint 6 by pins 110 and is opened by being rotated about the pins 110 toward the direction of the duct 112 until it is held substantially horizontal when air is discharged while it returns to a vertical state due to gravity when the fan stops. The duct connecting joint 6 has a sufficient length such that the top end of the shutter does not project outside when the shutter 8 is opened to become horizontal and therefore, the shutter 8 does not run against the inner wall of the duct 112 generating a chattering sound and against the duct 112 even when the duct 112 is bent at right angles at a place near the duct connecting joint 6 whereby the shutter opens and close at a predetermined angle at all times.
