Title: Switching mechanism for tray is sorter
Inventor: SAKURAI SABURO
IPC: G03G15/00
Filed: 1987-08-25
Abstract: PURPOSE:To perform the vertical motion of a tray in a highly accurate manner by fitting a wired ball in a ball hole of each guide post at both sides of the tray rear, coupling all trays together, and rotating a take-up wheel, having feed grooves as much as tray numbers, clockwise or counterclockwise. CONSTITUTION:Each guide post 5 is projected to both sides of the rear of each tray 3, and a ball 7 of a ball-cum-wire 6 is fitted in the ball hole 5a. Consequently, these trays 3 are coupled together in the same space in the vertical direction by the ball-cum-wire 6 at the specified space. Each tray 3 is moved up and down as each tray box 5 is engaged with each feed groove 4a by c.w. or c.c.w. rotation of a take-up wheel 4 provided with feed grooves as much as tray numbers. In this case, the tray 3 to be reached to a sheet inserting port 13 is accurately kept of its vertical distance with the tray 3 being situated on the upper part by regulation of the ball-cum-wire 6 in the guide post 5 with each other. Accordingly, it can be accurately opened to a position of the inserting port 13 and, what is more, feed rate is speeded-up.

Title: Manufacture of bond magnet molding material
Inventor: NUSHISHIRO KOICHI
IPC: H01F1/113
Filed: 1990-08-09
Abstract: PURPOSE:To make excellent in fluidity and magnetic characteristics without addition of a resin modifier and to improve mechanical strength by modifying ferrite magnetic powder with a phosphoric acid coupling agent after acid treatment at the time of mixing and kneading synthetic resin as the matrix and the ferrite magnetic powder. CONSTITUTION:Treatment with an acid such as hydrochloride acid, its adsorption by a powder surface, and then surface treatment with a phosphoric acid coupling agent, provide much water-resiliency. A preferable degree of acid treatment is that the pH of posttreatment magnetic powder is in the range of 2.0<=pH<=6.0. After acid treatment, treatment is made with a phosphoric acid coupling agent; the acid coupling agent used here is exemplified by di-2- ethylhexylphosphinate, di-2-ethylhexylphosphate, etc. A preferable amount of addition of the coupling agent is in the range of 0.1-1.0wt% to the magnetic powder. Less than 0.1wt% gives low magnetic characteristics of a molding, and more than 1.0wt% markedly decreases mechanical strength.

Title: Color inspecting apparatus
Inventor: MAEDA SATOSHI
IPC: G01J3/50
Filed: 1990-08-07
Abstract: PURPOSE:To separate and detect the structure distribution of a material under inspection and irregularities of colors by providing chromaticity coordinates within the color difference of 10 from each point on a straight line where the color difference of the chromaticity coordinates is separated by 20 or more with respect to a reference chromaticity coordinates on a straight line connecting achromatic colors so that the background has the equal lightness with the reference chromaticity coordinates. CONSTITUTION:The color of a material under inspection, which is the object of this invention and has a part that transmits light rays, is measured on a certain background color for the material under inspection. At this time, the chromaticity coordinates become the chromaticity coordinates wherein the color of the material under inspection is mixed with the background color. The background color and the reference chromaticity coordinates have the substantially equal lightness. Therefore, in the LC*H deg. coordinate system, H deg. is always constant even if the structure distribution is present unless color irregularities are present. On the contrary, the change H deg. suggests the presence of the color irregularities. Therefore, when the direction of H deg. is emphatically observed, the structure distribution and the color irregularities can be separated.

Title: Treatment of acrylonitrile/butadiene rubber
Inventor: KITANO KIYOYUKI
IPC: C08L33/00
Filed: 1984-10-08
Abstract: PURPOSE:To improve inexpensively the oil resistance of acrylonitrile/butadiene rubber without adversely affecting its properties, by immersing the rubber in a solution containing an ashless detergent-dispersant for lubricating oil. CONSTITUTION:Acrylonitrile/butadiene rubber is immersed in a solution containing an ashless detergent-dispersant for lubricating oil, selected from among succinimide, succinamide, succinate esters, their derivatives and their mixtures (e.g., polybutenylsuccinimidopolyethylenepolyamine). The treatment temperature is suitably about 30-80 deg.C and the treatment time is suitably about 5-300hr. In this way, the oil resistance of acrylonitrile/butadiene rubber can be improved because ion pairs are formed between an oxidizing component in an lubricating oil, which deteriorates the rubber, and the ashless detergent- dispersant for lubricating oil, to prevent the rubber from being deteriorated.

IPC: G08B21/00
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To efficiently prevent a driver from dozing while driving by time sequentially extracting a change component on moving images. SOLUTION: A video camera 4 successively picks up video images including the eye part of the driver 3 of an automobile 2 as the moving images. A CPU 7 calculates an area where luminance is changed between the latest video image and the previous video image stored in a frame memory 6 and performs an arithmetic operation for taking a correlation coefficient between the time sequential pattern of the area difference of the area where the luminance increases and the area where it decreases and a standard blink eye waveform. When the correlation coefficient exceeds a reference value, the point of time of a blink eye is extracted and the awakening state of the driver 3 is judged based on the extraction of the blink eye. When it is judged that the awakening state is lowered, treatment for preventing dozing while driving by an alarming device 12 is performed.

Title: Acoustic displacement meter
Inventor: ISHII YASUSHI
IPC: G01B17/00
Filed: 1985-09-25
Abstract: PURPOSE:To determine displacement on the basis of the ratio of two oscillation frequen cies, by constituting a multiple oscillator by connecting a measuring acoustic pipe to a Helmholtz resonator. CONSTITUTION:An acoustic pipe 3 is mounted on a container 1 to form a Helmholtz resonator and the resonant frequency thereof is set to fr'. A measuring acoustic pipe 2 is mounted on the container 1 and a microphone 6 of a sound pressure detector is inlaid with the interior of said acoustic pipe 2. The microphone 6 moves up and down and the displacement (x) to a stand 4 is quantity to be measured. When a sound source 5 is mounted on the container 1 to apply sound pressure to the interior of said container 1, the acoustic pipe 2 comes to a resonant state and the frequency is set to fr. An electronic circuit is connected between the microphone 6 and the sound source 5 to constitute a multiple oscillator simultaneously oscillating at frequencies fr', fr and fr'/fr is measured by a frequency ratio measuring circuit. The frequency fr is almost constant regardless of displacement (x). Therefore, the frequency ratio fr'/fr changes almost linearly with respect to the displacement (x). By this method, the displacement (x) can be determined. Further, because both frequencies also change in the same ratio with respect to the change in air temp., no effect is exerted on the frequency ratio.
