Title: Dozing state detecting device
Inventor: KANEDA MASAYUKI
IPC: G08B21/00
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To always stably detect a dozing state by inputting a face image detecting the positions and opening of eyes and judging the degree of awakening from the opened/closed state of the eyes based on the opening of the eyes. SOLUTION: An input image photographed by a TV camera 21 is converted into a digital value by an A/D converter 22 and the digital value is stored in a picture memory 23. An image data operation circuit 24 detects the density of vertical pixel strings of a face based on the input image data stored in the memory 23 and extracts a 1st extraction point based on the increment of density of the pixel strings and its changing state. An eye position detection circuit 25 detects the positions of eyes by selecting the eyes from curve groups. An opened/closed eye detection part 26 extracts 2nd and 3rd extraction points from the increment of density in the vertical direction and its changing state within a prescribed area including the positionally detected eyes and detects the opening of the eyes. An awakening degree judging circuit 27 judges the degree of awakening from the detection result of the opened/closed eyes sent from the circuit 26.

Title: Demultiplexing and photodetecting device
Inventor: MURATA SHIGERU
IPC: H04B10/07
Filed: 1987-08-20
Abstract: PURPOSE:To hold a photodetecting level nearly constant even if signal light varies in wavelength by controlling the reflection characteristics of a filter electrically. CONSTITUTION:The filter 111 can vary wavelength 2neLAMBDA (LAMBDA: diffraction grating period of filter 111, ne: effective refractive index of filter 111) corresponding to the largest reflection factor. Namely, even if the wavelength lambda1 of signal light varies, the impressed current of the filter 111 is controlled a control circuit 131 while the mean photocurrent of a photodetecting element A is monitored so that the photocurrent is maximum, thereby controlling the effective refractive index ne of the filter 111. Consequently, the level of signal light made incident on the photodetecting element A is held nearly constant even if the signal light varies in wavelength.

Abstract: PROBLEM TO BE SOLVED: To enable to continuously obtain the subject compound in high yield and selectivity without generating a polymer as a by-product by feeding each component of a chromium-based compound catalyst in a specific rate to a reaction zone at the beginning of a reaction to initiate the reaction of an α- olefin. SOLUTION: In continuously reacting (B) α-olefin to polymerize into a low polymer using (A) a chromium-based catalyst consisting of a chromium compound (A1 ), a nitrogen-containing compound (A2 ) which is an amine, an amide or an imide and an alkylaluminum compound (A3 ), each component of the component A and the component B are fed to a reaction zone so that each of molar ratios A2 /A1 and A3 /A1 is made higher than the molar ratio in a stationary state to initiate the low polymerization reaction of the component B. It is preferable to feed each component of the component A and the component B to the reaction zone while keeping A1 and A3 apart not to come into contact with each other, thus, the objective compound can be obtained in high purity.

IPC: B65H23/195
Filed: 1988-08-23
Abstract: PURPOSE:To prevent the breakage of a sheet at the time of the occurrence of a wrinkle on the sheet and wind up the sheet on a winder by correcting the circumferential speed reference of the winder by a tension deviation value when there is difference in speed between an unwinder and the winder.

Title: Finger chuck
Inventor: ITOU RIYUUZOU
IPC: B23B13/12
Filed: 1983-11-08
Abstract: PURPOSE:To guide the end part of the pipe onto the finger member accurately by providing the end of the pushbar with a lead-in guide having a pointed head. CONSTITUTION:A lead-in guide 20 having a pointed head is fixed on one end of a pushbar 14. The pointed head is stuck out of the end 12a of a finger member 12 so that the rear end of a pipe 26 is guided onto the finger member accurately. Furthermore, a spring 22 is fitted between the rear end of the pushbar 14 and the rear end of a holding member 16 which holds the finger member 12 allowing the finger member 12 to rotate freely. The spring 22 works on the lead-in guide 20 so that the lead-in guide 20 is pulled toward the finger member 12. Thus the pushbar can be pushed forward with an impact and also the lead-in guide can be pulled out instantaneously. Consequently the remainder of the pipe falls out of the finger member 12 and the lead-in guide 20 instantaneously without failure.
