Title: Smoke density measuring instrument
Inventor: MATSUSHIRO RYUICHI
IPC: G01N21/59
Filed: 1989-11-13
Abstract: PURPOSE:To accurately measure smoke density by providing a pulse driving circuit for a light emitting element and outputting the output difference of a light receiving element driven with pulses as a smoke density signal through a differential circuit. CONSTITUTION:A driving circuit 602 receives the signal of a timing generating circuit 601 to supplies a pulse signal S1 with a voltage VD to an LED 4 according to a signal T1, the V0 is varied with the output S0 of an integration circuit 606, and a phototransistor 5 generates an output S2. A circuit 603 holds the output S2 for a time T2 and the circuit 604 holds the output S2 of the PT 5 for a time T3. A differential amplifier 605 generates a differential output S5 with the outputs of the circuits 603 and 604. The influence of disturbing light is canceled by the circuits 603 and 604. An integration circuit 606 generates the mean output S6 of the output S5 and the output is fed back to the driving circuit 602 to control the VD. A differential amplifier 607 generates a differential output S7 based upon the S5 and S6 and a variation quantity detecting circuit 608 generates the peak-to-peak value of the AC component of the output S7 as the smoke density signal S. Consequently, the influence of the disturbing light is eliminated, drift and gain variation at three points is small, and a measurement error is small.

Title: Cd-wo device
Inventor: KUMAGAI MORIO
IPC: G11B7/00
Filed: 1989-11-13
Abstract: PURPOSE:To prevent overlapped recording onto a recorded part and to attain accurate connection between the recorded part and a new recording part by detecting the presence of a guide signal and a radio frequency signal on a disk to control the recording. CONSTITUTION:Since no guide signal is recorded on a CD for exclusive reproduction, a detection circuit 6 sends the state of absence of signal to a microcomputer 8, which controls inhibit of recording. In the case of recording to a write- once CD, the detection circuit 5 detects an RF signal from the signal of a radio frequency RF amplifier 3 to move a pickup 1, thereby detecting a border between the recorded part and the unrecorded part depending on the presence of the RF signal. Then the recorded part and the unrecorded part are connected smoothly. Thus, overlap recording onto the recorded part is prevented and the accurate connection between the recorded part and the unrecorded part is attained.

IPC: G06F3/0488
Filed: 1993-10-28
Abstract: PURPOSE:To prevent the generation of a detecting position error even when a signal level is varied in a coordinate detector using an electrostatic capacity coupling type cable added detection pen.

Filed: 1993-10-28
Abstract: PURPOSE:To obtain a highly detailed color image free from color shift, in printing a full-color image using a three-color or four-color surface sequential film, by precisely detecting the printing start end position on a sheet.

Title: Refrective index distribution measuring apparatus for optical fiber preform
Inventor: MATSUO SHOICHIRO
IPC: G01M11/02
Filed: 1993-10-28
Abstract: PURPOSE:To prevent a stoppage of measurement due to bubbles or the like contained in an optical fiber preform by providing a monitoring device of an output of a photodetector. CONSTITUTION:In a normal measurement, an output of a photodetector 28 detected with a motor 40 is repeated in high and low levels at a fixed interval depending on whether a laser light is intercepted with a chopper. Based on the information thus obtained, a computer 34 judges that the measurement proceeds normally and operates according to a program determined. But when the laser light fails to enter the photodetector 28 because of bubbles in an optical fiber preform the output of the photodetector 28 remains at the low level. Based on the information thus obtained, the computer 34 judges an error to occur from the output of the monitor 40 which does not turn to the high level when a fixed time passes even after it switches over to the low level from the high level. Then, the measurement of the preform is suspended according to the program determined and a shift is made to the measurement of the subsequent preform 10.

Abstract: PURPOSE:To reduce the number of working processes and to reduce a correction error by equipping the title system with a means to re-wire an existing wiring along the wiring route of a terminal connection in consideration of allowable free capacity and automatically executing processing for correcting the existing wiring. CONSTITUTION:The wiring route of the terminal connection is determined according to an interactive system, the free areas of respective both sides of segments are obtained along the wiring route by a free area calculating module 107, and existing wiring information included in the free areas is taken out while an existing wiring information extracting module 106 is referred to. Next, the intersection between the wiring route of the terminal connection and the existing wiring is checked, and it is checked whether capacity for wiring the terminal connection remains or not by calculating the free capacity obtained by subtracting information for the existing wiring from allowable free capacity information. When the wiring is allowed from the result of the checking, the existing wiring is re-wired at the interval for the allowable free capacity from the wiring route of the terminal connection. Thus, the number of the working processes can be reduced, and the correction error caused by the correction of the existing wiring can be eliminated.
