Patent JP-S58121897-A (JP)
Title: Digital speaker
Inventor: SUZUKI KENJI
IPC: H04R1/00
Filed: 1982-01-14
Abstract: PURPOSE:To obtain the miniaturized system having a minute change of sound field to any sound level and frequency, by arranging plural sound converters concentrically and arranging the converters at the more outside circumference proportionally corresponding to host bits. CONSTITUTION:Sound converters Si are arranged in concentric square form. Input signals are of SM (SIGNAL MAGNITUDE) form. Each bit of the input signal is applied to each operational amplifier OPi of a polarity inversion circuit 1 except the MSB and the MSB is applied to a non-inverting input transistor (TR) TRi of each operational amplifier. When the input signal is positive, since the MSB is 0, the TRi turns off, and ''1'' is outputted when each operational amplifier has input ''1''. Inversely, when the input signal is negative, the operational amplifier outputs -1 with input of ''1''. With input of ''0'', ''0'' is outputted. The signal (-1/0/1) is inputted to a drive amplifier 2-i outputting identically (-1/0/1) in terms of the voltage value to drive each unit Si of an acoustic converter. Each unit is arranged in corresponding to the weight at more outside circumference in propotioning to host bits.

Title: Formation of conductive circuit
Inventor: TOMITA SATORU
IPC: G03G15/05
Filed: 1981-01-16
Abstract: PURPOSE:To lower the impedance of a conductive circuit by moving the 2nd conductive member mounted with conductive filaments on the surface while bringing the same into contact with the 1st conductive member in moving intermittently, at least in a static state. CONSTITUTION:One side edge of a belt-like photoreceptor 1 consisting of a photosensitive layer 11, a conductive layer 13 and a base layer 15 is stripped away of its layer 11 to expose the surface 13a of the layer 13. A brush 17 flocked radially with filaments 17a contacting here is rotated by a driving means so that only the part of the layer 11 subjected to exposure generates conductivity, thereby forming the conductive circuit of the layer 13, the brush 17 and the earth 21. Since the brush 17 is rotating, always the different parts are brought into contact and the impedance of the conductive circuit is kept low.

Title: Cmos receiver circuit for conversion of ttl input signal level
Inventor: KARURU SEEDERUBAUMU
IPC: G11C11/419
Filed: 1993-01-18
Abstract: PURPOSE: To obtain a low power receiver circuit in which no DC current is consumed in a still state by using a feedback loop so as to decrease the DC current flowing to an input stage of the receiver circuit when an input signal is at a high level. CONSTITUTION: With an input signal Vin set to a high level, NFETs N1, N5 are conductive to connect nodes C, F to a GND. Thus, a PFET P4 is conductive and a node E is kept to a high level. An NFET 6 is conductive via a feedback loop 22 and an NFET N2 is nonconductive via a loop 20. Thus, in an inverter of an input stage 16, nodes C, D are open and the node D is kept to a high level via a PFET P1. Since the signal Vin is not enough to high to turn off the PFET P1, the PFET P1 is conductive. Each FET device is conductive in a 4th stage 21, and a PFET P5 has only a difference resulting from subtracting a level of a node G from the signal Vin to limit a DC current in the input stage 16. Thus, the low power receiver circuit not consuming the DC current is obtained.
