Abstract: PURPOSE: To reproduce analogue information accurately by adding prescribed elements of modulated digital signals on a basis of a prescribed system to generate the first and the second correcting signals and forming and recording and reproducing block signals.  
     CONSTITUTION: Switches SW 1  and SW 2  are switched according to sampling of analogue information, and digital signals which were subjected to PCM modulation, etc., are applied to a block signal constitution equipment and check signal generator through delay equipments 12W16 and 17W21. Meanwhile, digital signal elements are subjected to the addition processing, where 2 is adopted as a rule so that the same elements may be prevented from overlapping, in exclusive OR circuit 8, and the first error correction signal is applied to generator 24. Similarly, the addition processing is performed so that one or more digital signal elements selected at the first error correction signal generation time may be prevented from being used commonly, and the second error correction signal is applied to generator 24, and low-restoration impossible probability digital block signals obtained by adding these error correction signals and check signals such as CRC are formed to reproduce and demodulate analogue information accurately.

Title: Calling system for data terminal
Inventor: INOUE MITSUYOSHI
IPC: H04L29/08
Filed: 1987-05-27
Abstract: PURPOSE:To facilitate calling of a terminal in the case of the change of the code transmission speed and the transmission code condition by changing the internal condition by a line terminating equipment in accordance with training data from the terminal and sending this change information to an exchange to automatically change set contents. CONSTITUTION:Before originating a call, a data terminal DTE transmits training data which has its own transmission code condition and code transmission speed as information. In a line terminating equipment DCE, received transmission code condition and code transmission speed are discriminated by a central control unit 100, and the condition of an interface 101 or the fundamental clock of a clock generator 104 is repeatedly changed; and in the case of coincidence, this change is stopped and the transmission code condition and the code transmission speed are reported to the exchange. The exchange collates the transmission code condition and the code transmission speed of the terminal DTE with those of the destination, and the exchange transmits a connection completion signal to the terminal DCE and connects a corresponding exchange switch if communication is possible. Thus, calling of the terminal is facilitated even if the code transmission condition and the code transmission speed of the terminal are changed to perform communication.

Title: Exhaust particulate purifying device
Inventor: YOSHIDA HIDEJI
IPC: F01N9/00
Filed: 1995-05-26
Abstract: PURPOSE: To reduce the number of a sensor so as to regenerate a filter by using rotating speed of a diesel engine which is calculated using a detecting intake air rate on either one of calculation of an exhaust particulate collecting rate and regeneration of the filter. CONSTITUTION: A pressure difference which rear pressure detected by a pressure sensor 4b subtract from before pressure is found out while finding out an intake air rate detected by flow rate, pressure, and exhaust temperature sensors 11, 4a, 20 and the volume flow rate of exhaust gas from before pressure and an exhaust temperature. Engine rotating speed is calculated from the intake air rate. When it is judged that calculated engine rotating speed is a prescribed value or more, the collecting rate of exhaust particulate is calculated from found out pressure difference and the exhaust gas volume flow rate. If it is not on regeneration, it is judged whether the calculated collecting rate exceeds a prescribed value or not. Until the collecting rate exceeds the prescribed rate, it is judged as NO. When rotating speed is lower than the prescribed value and a collecting rate is not calculated, it is judged as NO. When the collecting rate exceeds the prescribed rate, regeneration of a collecting filter is started.

Title: Synchronizing coupler for vtr
Inventor: USUKI NAOJI
IPC: H04N5/93
Filed: 1990-05-17
Abstract: PURPOSE:To obtain a synchronizing coupler for a VTR formed with a small capacity of a memory by using a phase modulator so as to absorb the dispersion in the recording position of a recording medium. CONSTITUTION:A phase comparator 10 compares the phase of a vertical synchronizing signal of a reproduced video signal delayed by a delay circuit 9 and the phase of a vertical synchronizing signal of an external video signal and outputs a phase error voltage. Then the vertical synchronizing signal separated from the external video signal is phase-modulated by a phase modulator 11 in response to the phase error voltage and the result is used for a reference phase of a drum phase control circuit 6, which controls the rotary phase of a head drum 1. Thus, the phase of the reproduced luminance signal outputted from the head drum 1 is decided definitely independently of the effect of the recording position of the recording medium. Thus, the synchronizing coupling of the reproduced video signal is implemented for the VTR with a memory of a small capacity only required to absorb time axis fluctuation of the reproduced video signal.

Title: Light-applied physical quantity measuring instrument
Inventor: KAWAMURA TAKESHI
IPC: G01L1/24
Filed: 1989-05-22
Abstract: PURPOSE:To reduce the power consumption without shortening a measurable distance by supplying constant-level pulse light to an optical means at a constant period and leading out a light output corresponding to optical characteristics. CONSTITUTION:An LED 1 is applied with the constant-level DC voltage from an LED driving circuit 2 in constant cycles for a constant period, so a constant- level light pulse signal is outputted in every specific cycles for the constant period. Consequently, the power consumption on a transmission side is made less than that when the constant-level DC light is supplied to the LED 1 at all times by a quantity corresponding to the time of light nomemission. Further, a reception part receives output light from a sensor part by a photoelectric conversion part 5 and the light is converted and amplified by a photodiode 51 and a photocurrent amplifying circuit 52 into a voltage signal. This voltage signal is smoothed by an integration circuit 6 to extract only its low-frequency component, which is amplified 8 and then outputted.
