Title: Color signal clamp circuit
Inventor: TAKEYA NOBUO
IPC: H04N9/64
Filed: 1993-11-09
Abstract: PURPOSE:To keep the linearity of a color difference signal and accuracy of color component detection by excluding a gain adjustment circuit such as a color contrast in a clamp loop from the clamp circuit and adding a G-Y generation circuit to the clamp circuit. CONSTITUTION:A pedestal voltage of an output signal of a B-Y pedestal clamp circuit 101 is matched with a reference DC voltage 119. Thus, a gain adjustment circuit is excluded from a clamp loop. Thus, even when the gain is decreased close to 0, the clamp loop gain is not zero and the linearity of a color difference signal is not impaired in the clamp circuit 101. A pedestal voltage of the output signal of an R-Y pedestal clamp circuit 104 is made to match with a reference voltage 120. A B-Y clamp output signal 113 and an R-Y clamp output signal 114 which are coincident to each other in pedestal voltage are inputted to a newly provided G-Y generation circuit 108 to generate a G-Y output signal 118. Since the signals 113, 114, 118 are coincident with each other in pedestal voltage, a color component detection circuit 110 receiving these signals is free from malfunction.

IPC: H04N1/52
Filed: 1987-11-05
Abstract: PURPOSE:To reduce the multi-level level number, that is, memory bit number without losing picture quality by setting the multi-level number of one color among plural colors so as to be smaller than that of other colors. CONSTITUTION:An original to be copied is decomposed into R, G, B by a color scanner 1 and is read. A shading correction circuit 2 corrects the sensitivity unevenness and lighting unevenness of a light source. An MTF correction circuit 3 corrects the deterioration in the MTF characteristic at a high frequency region especially in the input system. The Y, M, C, Bk data subjected to color correction and UCR processing are processed for multi-level processing of binary or above by a gradation processing circuit 6. In order to emphasize the gradation of the data Bk especially, the gradation processing is applied by using more multi-level number than that for the data Y, M, C. In the output system using a laser printer, the gradation processing data is sent indirectly to the printer 7 via a memory 8.

Title: Adhesive resin composition and adhesive sheet
Inventor: MOCHIZUKI SHU
IPC: C09J7/02
Filed: 1997-09-25
Abstract: PROBLEM TO BE SOLVED: To obtain a resin composition which can perform bonding even at low temperatures in a short time, has high heat resistance and low hygroscopicity and scarcely undergoes e.g. package cracking by mixing polycarbodiimide with a bisalkenyl-substituted nadiimide. SOLUTION: The mixing ratio is such that 1-100 pts.wt. bisalkenyl-substituted nadiimide compound represented by formula II is used per 100 pts.wt. polycarbodiimide resin represented by formula I. In formula I, n is a positive integer; and A is a divalent organic group. In formula II, R1 and R2 are each hydrogen or methyl; and R3 is a diamine residue. When the amount of the bisalkenyl-substituted nadiimide compound used is smaller than 1 pts.wt., the compound can not exhibit any effect. When this amount is above 100 pts.wt., an adhesive sheet coated with the composition has poor adhesiveness, undesirably. Its typical example is N,N'-hexamethylene-bis(allylbicyclo[2,2,1]hept-5-en-2,3- dicarboxyimide).

Title: Packetized voice communication system
Inventor: WATANABE YOSHINORI
IPC: H04M3/00
Filed: 1984-12-27
Abstract: PURPOSE:To minimize deterioration of the reproduced voice by providing a data-stuff controlling part that inserts a pseudo data formed by extracting and interporating the data among those in the memory of which influence on the reproduced voice is minimum when the data quantity reaches the upper or lower limit value. CONSTITUTION:When the accumulation reaches the upper limit value, the data stuff part retrieves and removes one among all the data stored in the reception memory of which influence on the reproduced voice due to the removal is the least. Therefore, the reproduced voice positions between the upper and lower limit values. In case the voice data reaches the lower limit value, the data stuff part inserts the copy of the said data or a dummy data formed by interpolating the said data in the data cycle of which influence on reproduced voice due to the insertion is the least. Because the removal and insertion occurs being limited on one among the data of received-voice LCU stored in the temporary memory of which influence on reproduced voice is the least, the deterioration of voice is reduced.

Title: Dry etching method
Inventor: YANAGIDA TOSHIHARU
IPC: H01L21/302
Filed: 1991-10-02
Abstract: PURPOSE:To enable an SiO2 material layer to be dry-etched high in speed and selectivity and low in damage and especially in contamination. CONSTITUTION:A wafer temperature is controlled to be lower than a room temperature, and an SiO2 interlayer insulating film 3 is etched with the mixed gas of higher fluorocarbon(FC) compound such as syslic C4F8 or the like and carbon monoxide(CO). A high speed etching process is promoted by a synergistic effect of a sputtering reaction by CFx effectively generated from the higher FC compound and an oxygen extracting reaction from SiO2 by CO high in reducing property. Injection ion can be reduced in energy, so that it causes little damage to a single crystal silicon substrate 1, and a small amount of carbon-based polymer required for securing a base selectivity can meet requirements, in result the silicon substrate can be protected against particle contamination. By this setup, a device can be enhanced in yield and improved in throughput.
