Title: Viscosity modifier
Inventor: YOSHIOKA TOYOTARO
IPC: C09K3/00
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To obtain a viscosity modifier which is less affected by temp., can retain a viscosity in a certain range even under any conditions, and has excellent handleability throughout the year by using a compound represented by a specific formula. SOLUTION: This modifier comprises a compound represented by the formula (wherein R<1> , R<2> , and R<4> each is a hydrocarbon group; R<3> is a hydrocarbon group optionally having a urethane bond; R<5> is a branched or secondary hydrocarbon group; (m) is 2 or a larger number; (h) is 1 or a larger number; and (k) and (n) each is 1-500). It has a combination of properties which is not possessed by any known thickener. For example, it has a satisfactory thickening effect on water-based systems even when added in a small amount, despite its nonionic nature and relatively low mol.wt. It is stable to water and alcohols. Especially in the case of emulsion paints, the modifier not only thickens the paints, but enables most of the paints to have excellent flowability and leveling properties and have excellent viscosity adjusting effect under both low and high-shear conditions. Since it is less temp.-dependent and retains a viscosity in a certain range even under any conditions, it has excellent handleability throughout the year.

Title: Feedback amplifier
Inventor: MINATO TAKASHI
IPC: H03F1/34
Filed: 1991-09-10
Abstract: PURPOSE:To expand the dynamic range of the feedback amplifier circuit by connecting an output voltage of a current monitor circuit provided in a feedback section of a feedback amplifier so as to control a current branch circuit provided in a feedback section of the amplifier. CONSTITUTION:When an optical input level to a photodetector 1 is small, an input current of a preamplifier 2 is small, a voltage across a current monitor resistor 8 is very small and a base potential of a current branch transistor(TR) 10 is low, then the TR 10 is turned off. As a result, the preamplifier 2 acts like a feedback amplifier having a simple feedback resistor only. When an optical input level is increased, an input current of the preamplifier 2 is increased and a voltage across the resistor 8 is increased. After the voltage is amplified by a current monitor signal amplifier 9, the amplified voltage is fed to a base of the TR 10, which is turned on. Thus, part of the current flowing to the feedback section is branched to a Vee. Then the current flowing to the input of a TR 3 is suppressed and the dynamic range of the amplifier is expanded.

Abstract: PURPOSE:To reduce a noise of musical sound output, by attaching a dummy switch in a ladder-type D/A conversion circuit. CONSTITUTION:A signal 10 is always turned on apparently by short-circuiting a source and a drain by the dummy switches 25 and 26 with half of Tr size of switches 21 and 23. When a musical sound output ON signal 30 is set at an 'H', a T.M gate 27 is turned on, and a musical sound signal is outputted to the musical sound output 20, and when the signal 30 is set at an 'L', the output of an inverter 29 is set at the 'H' by turning on the T.M gate 27, and the (-) input terminal of an operational amplifier 7 is fixed at the ground (GND) by an N-channel (ch) Tr33, then, the musical sound output 20 is turned off. Thereby, since the dummy switches 25 and 26 absorb a switching noise, the overshoot and undershoot of the musical sound output 20 can be reduced, then, the noise can be reduced.
