Title: Hydrophilization method of glass and glass fiber
Inventor: OOZEKI TAKAO
IPC: C07F7/18
Filed: 1982-04-06
Abstract: PURPOSE:To give the hydrophilicity, improve the dispersibility and impart the water retaining property to glass fibers, by treating glass and the glass fibers with an organic compound having a specific structure. CONSTITUTION:About 0.01-10wt% one or more compounds expressed by the general formula (R1 is alkyl group; R2 is alkylene group; n is 0 or an optional integer) is applied to glass and glass fibers, dried and baked to give the hydrophilicity thereto. For example, the hydrophilizing agent is applied to the glass fibers by mixing in a binder in an apparatus for applying the binder thereto in the spinning process of the glass fibers, etc. The hydrophilizing agent is synthesized by saponifying completely or partially a polyvinyl acetate derivative obtained by the addition reaction of a silane compound having 3 alkoxyl groups and one organic group containing a mercapto group linked to the silicon atom with vinyl acetate in the presence of a radical polymerization initiator, etc.

Title: Automatic control circuit
Inventor: YAMAMOTO TAKESHI
IPC: H03L7/093
Filed: 1995-03-16
Abstract: PURPOSE: To provide a circuit capable of preventing the leak of the automatic control circuit of an IC constituted of a capacity incorporated with a loop filter, suppressing the influence of noise and reducing temperature dependency. CONSTITUTION: A rectifier amplifier 142 detects the amplitude of an output signal from a gain control amplifier 141 for performing the gain control of a chrominance signal to be inputted corresponding to a control voltage VGCA. A current output type level comparator circuit 143 compares the output voltage with a reference voltage VDET and outputs a current output IDET. Resistors R1, R2 and an operational amplifier 11 are inserted to this output, a charging/ discharging current is supplied through the resistor R1 to a smoothing capacitor C, and the output of the operational amplifier 11 is supplied to the gain control amplifier 141 as the control voltage. The current output IDET is branched into pathes of resistors R1 and R2, and only the current of the (R2/(R1+R 2)).IDET flowing through the resistor R1 is related to the charging/discharging of the capacitor C.  The detected current is reduced into R2/(R1+R2) and becomes a charging/discharging current and the same effect as the addition of capacitor of the multiple of (R1+R2)/R2 is obtained.
