Patent JP-H01136702-A (JP)
Title: Manufacture of improved wood
Inventor: KONISHI SATORU
IPC: B27K3/02
Filed: 1987-11-24
Abstract: PURPOSE: To sufficiently impregnate a timber with a large quantity of an insoluble noncombustible inorganic substance by eventually treating the timber with high concentration anion-containing treatment liquid in case of noncombustiblizing the timber with the liquid and cation-containing treatment liquid. CONSTITUTION: The timber is alternately impregnated totally three times or more with water solutions of water soluble inorganic compound for constituting cation part and anion part. Thus, compound is generated and fixed in a timber tissue to be modified for flame-retardancy. And, eventually, the timber is treated with anion-containing treatment liquid in such a manner that the concentration of the liquid is set higher than that of the anion-containing treatment liquid used previously. The final liquid is set to the high concentration, and treated to accelerate the diffusing velocity of the anion into the timber. Thus, the cation component impregnated into the timber is not discharged out of the timber but reacted therein, and hence a large quantity of the noncombustible inorganic substance can be fixed in the timber.

Title: Glass scattering-preventing laminated film
Inventor: TANAKA YOSHIO
IPC: B32B27/18
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To improve a weather resistance, transparency and a flaw resistance in the case where a thermoplastic film is used for window glass on an outdoor side, by laminating an ultraviolet-absorbing layer to at least one face of the thermoplastic film and making pencil hardness on the surface provided with the UV-absorbing layer to be at least H. SOLUTION: An ultraviolet-absorbing layer is laminated to at least one face of a thermoplastic film, and pencil hardness on the surface provided with the UV-absorbing layer is made to be at least H. The UV-absorbing layer is obtained by laminating a layer having a suitable UV-absorber e.g. a benzophenone-based, a benzotriazole-based, a triazine-based, a cyanoacrylate- based, an ester salicylate-based, a benzoate-based, an anilide oxalate-based, or an inorganic UV-shielding agent, etc., contained in resin components such as a thermoplastic, a thermosetting and an actinic ray-curable type resin. Further, in order to obtain the desired surface hardness, an actinic ray-curable type acrylic constituent is used. By this method, weatherability, transparency and flaw resistance can be improved.

Abstract: PURPOSE:To ensure power generation ability sufficiently by increasing gas flow rate flowing through a turbine during idling to increase the rotational frequency of the turbine in a turbocharger having a generator driven by an exhaust gas turbine. CONSTITUTION:During idling operation of a 4-cylindered engine, a throttle valve 23 in one suction manifold 12 communicated with two cylinders 7, 9 is fully opened, and fuel injection of a fuel injection nozzle 15 is stopped. On the other hand, a throttle valve 23 in the other suction manifold 11 communicated with the other two cylinders 8, 10 is throttled and fuel injection of the fuel injection nozzle 15 is conducted as usually. Thus the cylinders 8, 10 are operated, and the cylinders 7, 9 are forced to do pumping motion, whereby air discharged from the cylinders 7, 9 is merged into exhaust gas from the cylinders 8, 10 to be supplied to a turbine 4. Thus the rotational frequency of the turbine 4 is increased to increase regenerative voltage generated in a power generator 3.

Title: Centrifuge
Inventor: MORITA MASATAKA
IPC: B04B9/10
Filed: 1993-11-26
Abstract: PURPOSE:To use the difference in sedimentation velocity of particles without using a density gradient liquid to perform centrifugal separation by reducing the revolution with the lapse of centrifugal time. CONSTITUTION:This centrifuges is constituted of a driven motor, a rotating body 1 for holding a sample to be separated 3 and a control part for controlling the revolution. In the rotating body 1, the sample to be separated 3 contg. object particles is layered on a specific gravity liquid 4 consisting of cane sugar, etc., in a test tube 2. When centrifugal separation is performed, the revolution speed is decelerated in steps or continuously with the lapse of centrifugal time. Then, since particles whose sedimentation factor is larger than that of objet particles have a higher sedimentation velocity and their moving distance per a fixed time is larger, their sedimentation is faster than the object particles. As for particles whose sedimentation factor is smaller, since their moving distance per a fixed time becomes small, their sedimentation velocity becomes slow with the lapse of time and they are left near the surface of the liquid of the sample 3 in the rotating body 1. Thus, only the object particles are separated.

Abstract: PURPOSE:To measure the forbidden bandwidth of a semiconductor quantum well by a light absorption method or a light reflection method of high detection sensitivity, by utilizing the polarization dependency of optical transition probability between the valence band and the conduction band of semiconductor, and dying the forbidden bandwidth. CONSTITUTION:A monochromatic light obtained by a spectroscope is converted to a linearly polarized light by a polarizer 1, and further converted to a circularly polarized light by a 1/4 wavelength plate 2. A specimen 4 is irradiated with the light which has penetrated a beam splitter 3, and the reflection spectrum or the transmission spectrum is measured. The two polarizers 1, 2 are removed, and the reflection spectrum or the transmission spectrum is similarly measured by using the light which is not polarized. When the intensity difference between the spectrum of the circularly polarized light and the spectrum of the unpolarized light is examined, sharp difference between the two spectrums is generated at the wavelength corresponding to the forbidden bandwidth. Thereby the forbidden bandwidth can be easily detected.

Filed: 1988-11-25
Abstract: PURPOSE:To prevent malfunction due to an unnecessary reflected signal by converging light which is emitted by another vehicle on a light spot position detecting means by a converging means such as a condenser lens. CONSTITUTION:If a leading vehicle 24 is, for example, at a left-side position shown by a broken line, infrared rays 26 emitted from its exhaust pipe 24a passes through an optical path shown by a broken line and is converted on a right-side photodetection body 28. In this state, the leading vehicle 24 moves to the right side, the light passes an optical path shown by a solid line in a figure and is converged on a left-side photodetection body 28b, and the light spot is positioned on the left-side photodetection body 28b. When the leading vehicle moves to the left side, the light spot shifts in position to the right. Here, the movement direction and movement quantity of the light spot 32 are found to obtain the movement direction and movement quantity of the leading vehicle 24. Thus, the movement direction and quantity of the leading vehicle 24 are detected and the direction of the visual field 34 of a vehicle-to-vehicle distance detecting means 2 is controlled. Consequently, a reflected signal is only a signal which is reflected by the leading vehicle at all times and malfunction which is caused by an unnecessary reflected signal is evaded.

Filed: 1988-11-25
Abstract: PURPOSE:To prevent the contamination of an image in the case of successively forming the images by gating an image signal with the aid of an image effective signal obtained by detecting the trailing edge of a transfer paper and stopping the image from being written on a drum in the trailing edge of the image. CONSTITUTION:The title device is so constituted that at least either of a 1st CPU 22 and a 2nd CPU 11 generates the image effective signal whose range is smaller than the length of the transfer paper in a drum rotating direction based on the detected results by a trailing edge sensor 9 and read or exposure is performed within the range controlled with the image effective signal. Therefore, since toner does not adhere to the part of the drum where write is not performed, the toner does not adhere to the edge part of the transfer paper and there is no trouble that the upper fixing roller of a fixation part is contaminated by the toner. Thus, the contamination of the image is prevented at the time of successively forming the images.
