Filed: 1989-04-12
Abstract: PURPOSE:To apply the voltage to the electrodes of all memory cells and to secure the reliability with a semiconductor memory by applying the complementary voltage that can be set at high and low levels to all bit and word lines in a test mode. CONSTITUTION:For the outputs of a Y decoder circuit 3 and an X decoder circuit 4, a pulse signal PS and a signal, the inverse of PS received from an oscillation circuit 8 are set at high levels when a mode setting signal MS is kept in a normal mode and an inverted signal is outputted in response to an address signal AD received from an address buffer circuit 2. The signal PS and the inverse of PS are complementary with each other in a test mode of signal MS and are changed between high and low levels in the prescribed cycle. Then all output signals of the circuit 2 are set at high levels and the signals of pulse PS and the inverse of PS are outputted. As a result, the voltage of high and low levels are applied alternately and repetitively to all bit lines BL1 - BLN and word lines WL1 - WLN respectively. Then the electrodes of all memory cells MC11 - MCMN of a memory cell array 1 can be tested. Thus the reliability is secured for a semiconductor memory.

Title: Sound image rotation effect addition device
Inventor: NAKAMURA KAZUO
IPC: H04S7/00
Filed: 1990-04-10
Abstract: PURPOSE:To rotate a sound image position by outputting a signal resulting from an input audio signal subject to amplitude modulation by a sinusoidal wave signal and a signal resulting from the input audio signal subject to amplitude modulation by a cosine wave signal as left and right channel audio outputs respectively. CONSTITUTION:When a phase angle phi of a sinusoidal wave signal sin(2pift) and a cosine wave signal cos(2pift) is in a range of 0-pi/2, each signal multiplying a positive coefficient with an input audio signal (x) is outputted as left channel and right channel audio outputs Lout, Rout. Thus, a sound image is present in front of a listener. When the phase angle phi is in a range of pi/2-pi, the phase of the sinusoidal wave signal and that of the cosine signal are reverse to each other. Thus, when the phase angle phi is in a range of pi/2-pi, the sound image is present at the back side of the listener. As the phase angle phi increased for this period, the sound image is shifted from right to left. While the phase angle phichanges from 0-2pi, the sound image turns around the listener twice.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G5/05
Filed: 1989-04-12
Abstract: PURPOSE:To obtain the compact image forming device which has the satisfactory toner transfer rate and cleaning characteristic, and provides a stable picture free from picture quality variation by using spherical toner for development. CONSTITUTION:In the image forming device which performs both development and removal of unnecessary residual toner on the surface of a photosensitive body, and forms a toner image longer than the circumference of the photosensitive body, toner used for development is constituted of spherical toner. In this constitution, since the spherical toner is used, residual toner is also spherical, and it is in point-contact with the smooth surface of the photosensitive body. When discharge ions are supplied, they are almost uniformly adsorbed on the surface of the photosensitive body except the point where toner is in point- contact with the surface, therefore obstacle to uniform electrification, which is caused by residual toner, does not occur. As a result, toner is selected to suppress nonelectrostatic detaining to the photosensitive body, and the transfer rate is improved; additionally, a picture of satisfactory quality can be obtained by reversal development, etc. Since a cleaning blade does not abut on the photosensitive body, the service life of the photosensitive body can be prolonged.

IPC: H04L12/00
Filed: 1984-05-09
Abstract: PURPOSE:To increase an effective data transmission speed by comparing the data within a buffer memory with input/output signals and transfers signals only when no coincidence is obtained from said comparison. CONSTITUTION:The input signals of input/output devices b1-bn are read out successively via a switch circuit 5 by a command of a control circuit 3 and then written to a buffer memory 4. At the same time, the contents of the memory 4 stored previously by a cycle are also read out. A discordance detecting circuit 7 compares those input signals with the contents of the memory 4. The signals ''0'' and ''1'' are supplied to a discordance deciding memory 8 when the coincidence and discordance are obtained from said comparison respectively. Then the circuit 3 reads out successively the contents of the memory 4 and sends them to a transmission line 2 after P/S conversion performed via a signal converter 1. Then the contents of the memory 8 are referred to successively, and the contents of the corresponding memory 4 are transmitted to the line 2 only when the contents of the memory 8 is equal to ''1''. While no contents of the memory 4 is transmitted to the line 2. In other words, the transmission of data is carried out only when the input signal has a change. In such a way the effective data transmission speed is increased.

Filed: 1985-05-02
Abstract: PURPOSE:To detect the true target distinguished from a pseudo target, by employing a combination structure having both functions of an infrared type detector and a radio wave type detector. CONSTITUTION:An infrared detector 3 sends a received signal to a signal comparator 5. The comparator 5 fetches a signal as reference from a reference signal generator 6 to send it to a polarity decider 7 as target signal when the intensity of the received signal exceeds that of the reference signal and it decides on the polarity of the target signal to output the signal indicating the polarity to detection logical circuit 8. On the other hand, an antenna 10 sends the received signal to a signal comparator 12, which takes a signal as reference from a reference signal generator 13 to send the received signal to a polarity decider 14 as target signal when the intensity of the received signal exceeds that of the reference signal and it decides on the polarity, positive or negative, to send a signal indicating the polarity to the circuit 8. The circuit 8 outputs the target detection signal at an terminal 15 when the polarity of respective target signals by infrared rays and radio waves coincide with the signal feature of a metal target.
