Title: Photoelectric conversion device
Inventor: OOISO MITSUO
IPC: G06K9/20
Filed: 1979-10-17
Abstract: PURPOSE: To weaken a photoelectric conversion signal from the column on the business form and make strong a photoelectric conversion signal from the ball- point pen for OCR, by using a filter.  
     CONSTITUTION: As for the reflected ray from an image drawn by the ball-point pen for OCR, a black image is tinged with white since the reflection factor is high in case when wave length of the irradiation ray is long. Also, as for the column on the business form, since the reflection factor is low against the ray of specific wave length, having relatively short wave length, the reflected ray in case when said wave length has been irradiated is tinged with black. Therefore, the filters 3, 4 for obstructing the rays of long wave length and short wave length are provided on the front of the photoelectric conversion mechanisms 6, 5.

Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a method by which information is imbeded to a digital image and read with a simple device at a high speed. SOLUTION: Information to be imbeded to an image is prepared as a binary series of '0' and '1', and a specified value with an interval of 2<n> such as 2<n-1> (2j-1) is set to each coefficient used for coding a digital image to which the information is imbeded and a meaning of '0' or '1' is assigned to the specified value. In the case of imbeding the information '1' to a coefficient, the coefficient is normalized into the specified value to which the meaning of '1' is assigned and in the case of imbeding the information '0' to a coefficient, the coefficient is normalized into the specified value to which the meaning of '0' is assigned so as to record the information in the unit of one bit to each coefficient and other information is multiplexed and imbeded to the digital image.  In order to read the imbeded information, the information is read by checking only a bit value at a specific position decided by a value (n) with respect to the coefficients of the digital image to which the information is imbeded.

Title: Glass plate breakage detector
Inventor: NAGAMINE KENJI
IPC: G08B13/04
Filed: 1981-08-27
Abstract: PURPOSE:To improve reliability against malfunction, by a method wherein detection is not performed before a galss plate is broken or destroyed, and the breakage state is indicated in visual indication and an alarm. CONSTITUTION:If a signal detected by a piezoelectric element P contains high- frequency component generated at breakage of a glass plate, the high-frequency component is separated by a resonance circuit 2 and detected and amplified by a transistor Q1 and then the amplified current is held as collector current of Q2 for a given time. Thereby high-frequency component at usual breakage is detected more rapidly than low-frequency component and synchronization miss is prevented. Low-frequency signal passing through BPF constituted by LPF5 is applied to gate electrode G of FETQ3. Signal off negative voltage beyond the gate cutoff voltage produces cutoff state between drain electrode D and source electrode S thereby holding current passes through a resistor R7 and is introduced to gate of thyristor Q4. Thus Q4 is rendered conductive to light LEDD1 and passes through power source polarity converting member C and operates an external alarm D.

Title: Individual resuming control system in exchanging system
Inventor: FUKUDA KIYOMITSU
IPC: H04Q3/545
Filed: 1987-05-28
Abstract: PURPOSE:To attain an individual resuming control by having an executing processing means to apply for a common line signal system as an information communicating control between function processors and when one function processor is resumed, informing other function process of the recovery of a call. CONSTITUTION:The signal system of common signal lines 31 and 32 applies for a CCITT No.7 signal system. When a line control processor 23 at a receiving side executes the individual resumption due to a trouble, the line control processor 23 transmits RLS (releasing) information through the common line 32 to a call control processor 21. The call control processor 21 to receive the RLS information transmits the RLS information through the common signal line 31 to a line control processor 22 at a calling side, releases the channel to connect a calling terminal 41 to a receiving terminal 42 and transmits RLC information through the signal line 32 to the processor 23. Thus, the processor 22 completes the recovery, and transmits the RLC information through the signal line 31 to the processor 21. The processor 21 to receive this completes the recovery. When one function processor is resumed, the recovery of the call to other processor is informed by the common line signal system and thus, the individual resuming control in the exchanging system can be executed.

Title: Manufacture of cold rolled sheet of al-alloy containing mg
Inventor: TOTSUGI YOICHIRO
IPC: C22C21/00
Filed: 1990-05-24
Abstract: PURPOSE:To obtain a cold rolled sheet of alloy without periodic fluctuation of thickness due to the difference of thickness of oxidized film by the temp. difference inside a coil when annealing by specifying the composition of Al-alloy ingot contg. Mg, cleaning liquid and cleaning time for this. CONSTITUTION:After Al-alloy ingot contg. Mg >=0.3% is performed with soaking treatment, this ingot is cleaned with the lye of >=pH10 or acid solution of <=pH3 for 1-500 sec after performing hot rolling and succesive annealing and, after that, cold rolling is executed. The reason for confining the Mg content >=0.3% is that the oxidized film on the surface is difficult to grow when Mg content is under 0.3% and thickness fluctuation is not generated. The removing effect of the oxidized film with the lye under pH10 or acid liquid over pH3 is small and they are not suitable and sufficient removing effect is hopeless when cleaning time is under 1sec and the surface of sheet is excessively etched when this time is over 500sec.
