Title: Data processor
Inventor: KIMURO SHIGEO
IPC: H03M5/20
Filed: 1980-03-31
Abstract: PURPOSE:To make efficient the data processing of an unpack form, by processing the zone and digit part of a byte data with lach of two sets of registers. CONSTITUTION:The hexadecimal number, e.g., 3 corresponding to the zone loaded to the logical operation circuit 9 is stored in the zone register 7Z of the register 4. Then, the data of the form of zone Zn and digit Dn in one byte unit is read out from the main memory 1 with the access request of CPU3. Further, the gate is controlled with the set of register stored and written in FF in advance, and digits are written in and stored in the digit section register D with the switching signal 12D and clock signal 13D. Thus, the data is normalized with registers 7Z, 7D and the data is written in the memory 1 until it reaches the designated length. The data processing time of zone section is reduced with the system processing the zone and digit through the use of registers of two sets and 4-bit, allowing to efficiently make the data processing of the unpack form.

IPC: H04R3/02
Filed: 1982-03-16
Abstract: PURPOSE:To prevent the occurrence of the echo between speakers and prevent howling, by providing a digital delay circuit between a microphone input part and an amplifying stage of a loudspeaker and delaying an inputted sound signal by a preliminarily set prescribed time. CONSTITUTION:The sound signal inputted from a microphone 1 is converted to a digital signal through an A/D converter 2 by pulses from a sampling pulse generator 4 and is stored in a memory 3 successively. The first-the n-th clock pulses of a reference clock frequency generator 5 are counted through a counter 6 by an address pulse counter 7 and are decoded as the first-the  n-th addresses of the memory 3 through an address decoder 8. The value (n) is changed by the output of a repeat frequency determining counter 9 which is set by a delay time designating switch 10. The signal read out from the memory 3 is transferred to the amplifier incorporated in the loundspeaker through a D/A converter 12, thus preventing the occurrence of the echo between speakers and preventing howling.

Abstract: PURPOSE:To prevent external equipment from executing a malfunction with error data by providing a turning-off detecting circuit to detect that an output signal becomes a turning-off condition and generate an alarm signal and a noise detecting circuit to detect that a noise signal is superimposed to the output signal and generate the alarm signal. CONSTITUTION:An input light signal is converted to an electric signal by a photoelectric converting means 1, shaped to a pulse signal by a waveform shaping means 2 and thereafter, outputted to external terminal equipment. A turning- off detecting means 4 of an alarm means 3 detects that the output pulse signal of the waveform shaping means 2 is not changed over a constant period, detects the abnormality of a light link system and generates the alarm signal. A noise detecting means 5 generates the pulse signal of a constant width triggered by the fall part of the output pulse signal of the waveform shaping means 2 in the internal part, detects the phase difference between the pulse signal and the output pulse signal and detects whether or not the noise pulse is superimposed at an output pulse signal. Thus, when the noise pulse is superimposed, the alarm signal of the data error is generated at the external equipment and the malfunction of the external equipment can be prevented beforehand.

Title: Photoelectric conversion device
Inventor: HISAMATSU TADASHI
IPC: H01L31/04
Filed: 1993-03-02
Abstract: PURPOSE:To provide a new fundamental idea of solar cells which operate in reverse-biased conditions for the dramatic improvement of photoelectric conversion efficiency, by reverse-biasing the solar cell and using the thus optically generated carriers as a trigger to cause an avalanche breakdown in a depletion layer. CONSTITUTION:A second element 2 is made of a heavily doped semiconductor material which includes a p<+>-n<-> junction and a relatively narrow forbidden band. When it is reverse-biased through a first element 1, a strong electric field is formed in its depletion layer. The second element 2 is injected with electron-hole pairs obtained by absorbing solar light mainly in the intermediate and long wavelength range which was not photoelectrically converted in the first element. In the mean free path the electron-hole pairs get energy from the strong electric field and thus collide with atoms. The resultant covalent- bonded electrons are excited to produce a conduction band, and thus new electron-hole pairs are generated. This causes an avalanche breakdown, and the avalanche multiplication process provides a photocurrent several to several hundred times that in conventional solar cells.
