Title: Digital audio reproducing device
Inventor: TAKEUCHI TOSHIFUMI
IPC: H03H17/02
Filed: 1987-08-31
Abstract: PURPOSE:To attain an N-fold of over-sampling regardless of the converting time of a D/A converting circuit by parallelly connecting the D/A converting circuit in plural numbers to the N-fold of an over sampling digital filter and adding the plural numbers of D/A converting circuit outputs. CONSTITUTION:Since the two numbers of D/A converting circuits 3 and 4, for example, are parallelly connected to the N-fold of a sampling frequency N.Fs and sampling data are D/A converted at every other circuit, the sampling frequency of the D/A converting circuit for one circuit can be made N/2.Fs. Further, an audio signal, which is outputted by adding the signal of the parallel D/A converting outputs in two numbers, goes to be the N-fold of a sampling frequency signal. Thus, the N-fold of the over sampling can be executed without being limited by the converting time of the D/A converting circuit.

Title: Silicon-containing copolycondensate and preparation thereof
Inventor: NAGASAKI YUKIO
IPC: C08G77/50
Filed: 1993-08-31
Abstract: PURPOSE:To produce a silicon-containing copolycondensate having a high content of Si, a polymerizable vinyl group and high oxygen permeability by the copolycondensation of specific compounds each containing styrene, dimethylsilyl and trimethylsilyl groups. CONSTITUTION:p-Vinylbenzyllithium, 1, 2-bis(chlorodimethylsilyl)ethane and allyl-trimethylsilane are copolycondensed in an adequate solvent to produce a silicon-containing copolycondensate consisting of the structural units represented by formulae I, II and III wherein Me is methyl. The oligomer thus produced is a useful starting material for synthesizing functional polymers, applicable to air separation membranes and resists, because of its high oxygen permselectivity resulting from the presence of Si both in the side and straight chains, and polymerizable vinyl residue in the styrene group. The method is controllable with respect to combination of the structural units represented by formulae I, II and III, and composition and molecular weight of the oligomer depending on the specific purposes for which it is used.

The noises are removed from the output signal with a waveform shaping circuit 25. The signal is inputted into an operation amplifier 32 through resistors r6 and r7. The voltage, which is generated in correspondence with the position of the movable contact of a variable resistor r10, is changed. Therefore, the movable contact is slid to an appropriate part, and the voltage corresponding to a contract flow rate is generated at the movable contact. The voltage corresponding to the contract flow rate is integrated with the operation amplifier 32. The flow rate exceeding the contract flow rate is changed into a capacitor c4.  The pulse signal, which has the frequency corresponding to the flow rate exceeding the contract flow rate, is outputted from an operating circuit 26 into a pulse counter 28. The pulses are counted and displayed.

IPC: H04N5/14
Filed: 1984-10-17
Abstract: PURPOSE:To eliminate sinking of a low brought part and to improve a gradation characteristic and repeatability of a color in an automatic gain controller for fixing an output signal independent of an input signal not by executing the automatical gain control but fixing to a certain gain when the input signal exceeds the prescribed level. CONSTITUTION:Normally, an amplifier 2 modulates an output (VOUT) of a gain control amplifier 1, which is modulated by a WBLK pulse, and a detector 3 detects it as a DC signal, while an integrator 4 integrates it to drive a gain controller 5. Here a so-called gain control system is applied which controls the gain control amplifier 1 and obtains the certain output (VOUT) independent of an input (VIN). When the input (VIN) exceeding the prescribed level is obtained, the gain controller 5 fixes the gain of the gain control amplifier 1. Namely, when the input exceeds the prescribed level, the automatic gain control system is switched to a fixed gain control system. Thus the output (VOUT) in proportion to the input (VIN) can be obtained.

Abstract: PURPOSE:To prevent a blackening phenomenon in inactive operation by supplying a fine current to electrodes made of a battery element, detecting the inner resistance value of the battery element and supplying an oxygen concentration detecting current to electrodes made of oxygen pump elements when said resistance value is below a reference. CONSTITUTION:When an ignition switch is on, a fine current supply command is issued.
