Title: Correcting method of varied length of optical path of cuvette
Inventor: MIMURA TOMONORI
IPC: G01N21/01
Filed: 1982-03-29
Abstract: PURPOSE:To remove the influence of variation of length of optical path at the time of automatic analysis of general specimens for test by such an arrangement wherein the degree of extinction of each cuvette is measured by using colored liquid and water, and based on the measured values, a coefficient for correcting length of optical path is obtained for each cuvette in advance. CONSTITUTION:From a sample cup 4 placed on a reaction disk 21, a fixed amount of specimen (pure water) is sucked up by a probe 40 and discharged into a cuvette 22. A fixed amount of colored liquid is poured into the cuvette from a reagent bottle 31 and the cuvette 22 is measured photometrically by using 2 wavelength while rotatating it. All cuvettes are measured for degree of extinction and the results are memorized in a microcomputer. Similarly, the degree of extinction is measured by using pure water instead of the colored liquid. From a total of 4 measured values, a correction coefficient of the optical path of each cuvette is calculated by the microcomputer and the result is also memorized in it. When general specimens for test are to be measured, photometrically measured values by using 2 kinds of wavelengths are to be corrected by multiplying the correction coefficient of each cuvette thereto.

Abstract: PURPOSE:To stably develop whole surface wetting of a solution to over seed for growing solution, by moving a solution bath having a larger thickness of washing solution than that of growing solution relatively to a solution partition plate and carrying out epitaxial growth. CONSTITUTION:When starting temperature of the first layer p-Al GaAs growth is attained by drop in temperature, a substrate sliding plate 18 is moved in the arrow direction and the substrate crystal 19 is positioned under the bottom of a thin layer solution 42 a for the first layer growth. Crystal is grown at a fixed growth rate on the surface of the substrate crystal 19 since the solution has stable nucleus formation. After temperature is lowered by 1-3 deg.C and the first layer grows into a given layer thickness, the substrate crystal 19 is moved, stopped and arranged under the bottom of a thin layer solution 42b for the second layer p-GaAs growth. In the movement, the substrate crystal is passed through a washing solution 41b. Since over seed is placed even on the washing solution, a large amount of formed nuclei are not attached to the surface of the first layer growth and high-quality crystal surface free from defects is obtained. Successively, the substrate is slid, temperature is dropped by 1-2 deg.C as the second layer and desired thickness of growth layer can be obtained.

Title: Image forming device
Inventor: HANEDA SATORU
IPC: G03G15/08
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To maintain proper cleaning performance by making the discharging capability of toner discharged to an image forming body from a toner recycling means higher than the recovering capability of the toner left after a transfer action and recovered to the toner recycling means from the image forming body. SOLUTION: A photoreceptor drum 10 is softly rubbed by a rough magnetic brush at a discharge time so that the toner is excellently discharged by the magnetic brush in order to set the discharging capability by the toner recycling device to be higher than the recovering capability. Since the rough magnetic brush is weak with respect to the sticking toner and roughly actuated, the recovering performance thereof is bad but it is good because the toner can be discharged also from the magnetic brush set near to a sleeve 110 at the discharge time.  It is good that the filling rate of magnetic grains in the magnetic brush at the rubbing part thereof recovering and discharging the toner is set to be 5 to 30% because the toner attached to the magnetic grains becomes easy to be moved along the bristles of the magnetic grains extending over the upper layer from the lower layer of the magnetic brush. It is specially preferable that the filling rate is set to be 10 to 20%.

Title: Method for preventing dazzling light
Inventor: HASHIMOTO TAKAAKI
IPC: G02B27/28
Filed: 1983-03-24
Abstract: PURPOSE:To prevent the dazzling light from a car running in the opposite direction by fitting headlights or polarizing filters fitted to front surfaces and an eccentric filter fitted within a driver's visual field so that the principal axes of polarization of the both are within a specific angle range. CONSTITUTION:A polarizing filter 3 whose principal axis 5 of polarization is set to 0 deg. is arranged in front of a headlight 2 which emits dazzling light L, and a polarizing filter 4 which crosses the principal axis 5 of polarization at an optional angle is arranged behind the polarizing filter 3; when those filters are seen through, the cutoff rate B of light becomes larger and larger as the intersection angle A of the principal axis 5 of polarization becomes larger and larger. When the intersection angle A is 90 deg., the cutoff rate B of light is maximum, and when the angle is between 90 and 180 deg., the cutoff rate B decreases symmetrically. The light from the headlights 2 of a car running in the oppsite direction is a transversal wave which has directivity in a plane perpendicular to the moving direction, so two polarizing filters are arranged so that their principal axes 5 of polarization are at 45-135 deg. to the straight direction of the ight L, thus preventing the dazzling light L.

Title: Data converting device
Inventor: KOMIYAMA TADASAKI
IPC: H04L69/40
Filed: 1987-03-06
Abstract: PURPOSE:To ensure the proper transmission of data between a duplex control device and a single control device by delivering the transmission data to the control device of the remote side by a control means via an interface in a state where a protocol is converted. CONSTITUTION:The transmission of data is performed between control devices 1 and 1' and a control device 2 via a data converting device 3 while the device 2 is controlling a plant B. In this case, a control device 2' is kept under a waiting state and therefore no significant data is sent to system buses 1b and 1b' from a data converting device 3'. Thus data are never sent simultaneously to both buses 1b and 1b' from both devices 3 and 3'. At the same time, data are sent to the device 2' from devices 1 and 1' via the device 3'. However the device 2' does not fetch the data. Then the device 2' becomes active and the transmission of data is carried out between the device 2' and the devices 1 and 1' via the device 3' as soon as the device 2 has a fault and is set under a waiting state.

Title: Vapor-phase etching method for wafer
Inventor: OKAMOTO KIMITAKA
IPC: H01L21/302
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a method, in which etching is enabled in a temperature region, in which thermal strain is not generated, and fine particles can be removed from the whole region of a device, by feeding sufficient N2 gas into a device system, removing moisture and O2 in a furnace, introducing a specific quantity or less of dilute CIF3 gas and conducting vapor-phase etching without external heating. CONSTITUTION:In a vapor-phase etching in which a clean Si surface is exposed as the preprocess of the vapor-phase film formation of a wafer, sufficient N2 gas is fed into a device system, moisture and O2 in a furnace are taken off, dilute CIF3 gas of 1000ppm or less is introduced as an etching gas, and vapor- phase etching is performed without external heating. A large quantity of N2 gas are fed, moisture and O2 in the furnace are removed, the sufficient gas is replaced, and dilute CIF3 gas of 1000ppm or less is introduced. Since a vapor- phase etching reaction by CIF3 gas is accompanied by strong heat generation and temperature distribution is easy to be generated, it is desirable that sufficiently dilute CIF3 gas is used for uniform etching. Vapor-phase etching is completed, the gas is replaced enough with N2 gas, H2 gas replacement is executed sufficiently, and heating for vapor growth is conducted.
