Title: Charge-coupled device for processing analog signal
Inventor: IMAI MASAHARU
IPC: H01L29/762
Filed: 1985-03-11
Abstract: PURPOSE:To reduce a high frequency distortion by narrowing a charge transfer line of a signal charge injection part under a signal sampling electrode and by making a transfer cell area of said electrode smaller. CONSTITUTION:A width W2 of an electric field transfer line boundary 12 of a charge transfer line of a charge injection part due to the voltage input injection formed by a transfer cell A under a control electrode 15, an input diode 14, a transfer cell B under a signal sampling electrode 16, etc., is made nallower than a width W1 of a charge transfer line boundary 11 of a main charge transfer line formed by transfer cells D, F... and accumulation cells C, E, G.... Consequently as soon as a transfer cell area under the signal sampling electrode is made smaler, and a sampling signal is turned off, a built-up charge of the cell B is pushed back to a diode 1 through the cell A. Some of a charge of the cell B is mixed in the cell C, and the mixed amount becomes smaller in proportion to the area of the cell B, whereby a harmonic distortion can be reduced.

Title: Lining method for conduit
Inventor: HAMADA SUSUMU
IPC: B29C51/00
Filed: 1980-04-08
Abstract: PURPOSE: To maintain an excellent adhering property of a cylindrical lining material for the inside surface of a conduit by a method wherein a string-formed member is connected to a trailing end of the lining material and then an appropriate tension is applied to the lining material while introducing the lining material into the conduit.  
     CONSTITUTION: One end of the cylindrical lining material 1 coated with an adhesive on the entire of its inside peripheral surface is fixed to a leading end of the conduit 6 or the like, and the lining material 1 is passed in the conduit 6 by feeding compressed air into the material 1 through a tank 3 by a compressor 5. In this case, the string-formed member 1' is preliminarily connected to the trailing end of the lining material 1 so that the tension can be continuously imparted to the material 1 even after the material 1 reaches a point corresponding to about one half of the length of the conduit 6. Accordingly, the lining material can be adhered to the inside surface of the conduit at a sufficiently high speed and without occurrence of penetration of air bubbles.

Title: Detection system of frame synchronizing signal
Inventor: HIRAKI MOTOMASA
IPC: H04L7/06
Filed: 1979-04-16
Abstract: PURPOSE:To prevent mixture of general signals and the frame synchronizing signal by making general signal and the synchronizing signal different from each other in pulse amplitude value or making pulses of general signals and the synchronizing signal different from each other in polarity. CONSTITUTION:In respect to frame synchronizing signal pulse P2, the amplitude peak value is larger than that of general signal pulse P1, and threshold level 3 for frame synchronizing signal detection is set to a high value. Consequently, the output of receiving circuit 1 for general signals where a general signal pulse train is inputted becomes as shown in b, and the frame synchronizing pulse becomes as the amplitude peak value of general signal P1. Then, only pulses of frame synchronizing signal P2 detected by threshold level 3 are outputted as the output of frame synchronizing signal receiving circuit 2. Otherwise, frame synchronizing pulses different from general signals in polarity may be used.
