Title: Exhaust product recovery device for exhaust emission control system
Inventor: YAMAMOTO ISAO
IPC: F01N3/021
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To improve the exhaust purifying performance and effectively clean the filters of an exhaust emission control system by constituting a purifying body by two, the first and second purifying chambers made through the splitting of an exhaust pipe in its halfway portion and arranged in parallel to each other and by arranging in the respective purifying chambers injection nozzles which selectively inject fluid to clean the filter SOLUTION: When the engine is running, a fluid force feed part 40 is controlled to force-feed fluid in an fluid tank 24 to a second fluid supply pipe 30-2 for example, which pipe is selected by the switching of a valve 16, and injects the fluid from a second fluid injection nozzle 32-2 toward the filter in a second purifying chamber 8-2 to clean the filter through the removal of products adhering thereto. At which time exhaust gas from the engine flows through a first fluid supply pipe 30-1, thus the fluid is not injected from a first fluid injection nozzle 32-1, and products in the exhaust gas is removed by the filter in a first purifying chamber 8-1. An ozone supply means 44 supplies ozone to oxidize Nox in the exhaust gas.

Title: Distance measuring optical system
Inventor: YOKOTA HIDEO
IPC: G02B3/04
Filed: 1978-12-11
Abstract: PURPOSE: To improve distance measuring capacity by specifying the materials and shapes of a light projecting lens and a photodetecting lens.  
     CONSTITUTION: A light projecting lens 2 and a photodetecting lens 6 are made of single lenses which are formed by synthetic resins such as polymethacrylate resins. There are so formed as to satisfy 1<f.(1/R 1 +1/R 2 )<1.6 where the focal lengths of the respective lenses 2, 6 are let f, the radius of curvature of the 1st face on the object side R 1  and the radius of curvature of the 2nd face R 2 . Also, they are formed to such shapes that one face of each of the lenses 2, 6 becomes subsequently smaller in the curvature of the periphery than in the curvature at the vertex. Wiht this arrangement, at the time when the luminous flux emitted from a light source 1 is refracted and converged by the projecting lens 2 and is radiated to the surface of the subject 7 and the luminous flux scattered and reflected by the subject 7 is condensed to the photodetecting surface of a photoelectric converting means 3 by the photodetecting lens 6, the extension of the maximum measurable distance becomes feasible while the illuminance of the distance measuring luminous flux image on the photodetecting surface of the photoelectric converting means 3 is being improved.

Title: Thermal transfer element
Inventor: SHIMIZU AKIO
IPC: B41J31/00
Filed: 1990-06-11
Abstract: PURPOSE:To enable the same process to be applied as for thermally plastic resin by adding thermally plastic resin and solvent-soluble wax having a hydroxyl group in the molecule as a binder in an ink layer. CONSTITUTION:The content of solvent-soluble wax having a hydroxy in the molecule in a binder is preferably be 10 to 20wt.%. If the content of the solvent- soluble wax having a hydroxyl in the molecule in the binder is 10wt.% or less, the resin binder cannot display the effect to eliminate its own defect. If the content of the wax in the binder is 20wt.% or less, the wax binder begins to indicate its defeat, so that the print becomes less resistant to rubbing. The thermally plastic resin which is used as a binder by mixing it with the solvent- soluble wax having a hydroxyl in the molecule is ideal for this type of application and is such as polyamide and an ethylene-vinylacetate copolymer.

Abstract: PURPOSE:To prevent the deviation of an original and the incidence of flared light caused by an original pressuring plate is inadvertently opened by providing a means regulating the original pressuring plate so that it is not released from an original pressing state when the original is read by a read means. CONSTITUTION:The original is set at a prescribed position and the copying thereof is started by an operation part by closing a pressure plate 1. Then, the scanning of the original is started and an image sensor 10 is moved left and right while reading the image of the original placed on an original platen glass. At this time, the plunger 6a of a solenoid 6 being under a state that it is pulled in a right direction by a spring 6 is moved simultaneously with the start of the copying and the stopper fitting 1b of the plate 1 is locked. Since the locking state is continued during the copying and the plate 1 cannot be opened even when it is inadvertently opened during the copying, miscopying is prevented from being executed. When the copying is finished, an initial state is obtained and the plate 1 is freely opened and closed.

IPC: G11B7/2535
Filed: 1986-07-02
Abstract: PURPOSE:To obtain a base film for an optical recording medium which does not produce deformation owing to curling and lowering of flatness, when an optical recording layer, a protecting layer and a reflecting layer are prepared by means of vapor-deposition or sputtering, and is fit for applications, by consisting of a specific biaxially oriented polyethylene terephthalate film. CONSTITUTION:An optical recording film consists of a biaxially oriented polyethylene terephthalate film whose heat shrinkage is 0-1% at 200 deg.C in its longitudinal direction and heat elongation is 0-2% at 200 deg.C in its axial direction. Polyethylene terephthalate is a homopolymer, a copolymer or a blend thereof whose molecular constitution comprises 80mol% or more polyethylene terephthalate and m.p. and intrinsic viscosity are 250 deg.C or more and 0.4-1.0 respectively. As the thickness of the film, 7-200mum is preferable. Heat setting under a condition of being unstretched in the axial direction is carried out at 180-210 deg.C. Out of this range, it is difficult to obtain a film having good thermal characteristics.

CONSTITUTION:The PFN 6 is connected to the anode of the thyristor 7 via the saturable reactor 5 and a branch A composing of the saturable reactor 5, the PFN 6 and a pulse transformer 8 is formed. Then a CR circuit composing of the capacitor 10 and the resistor 11 is connected between a connecting point of the saturable reactor 5 and the PFN 6 and a cathode of the thyristor 7 to form a branch B. In this case, the circuit constant is decided so that the time constant of a loop through the branch B to a semiconductor switch is decreased than the time constant of the loop through the branch A. When the thyristor is triggered to be turned on and both electric charges are discharged, a current flows to the branch B and the entire face of the anode is the conducting region by the discharge current. Then a current flows to the branch A to produce a pulse driving a magnetron.

Title: Method and device for controlling convection
Inventor: WAKAYAMA NOBUKO
IPC: C30B15/20
Filed: 1999-06-01
Abstract: PROBLEM TO BE SOLVED: To simply and effectively suppress natural convection which is caused by a gravitational force and flows toward the upper direction or the lower direction at the central part of a liquid by applying a magnetic force in the horizontal direction, being generated by a gradient magnetic field, to the liquid from the outside to center part or from the center part to the outside. SOLUTION: When flow 1 of natural convection such that the liquid in a vessel flows toward the upper direction based on the gradient of the temp. or the concentration at the central part is occurred by a gravitational force, a magnetic force, which is generated by a gradient magnetic field in the horizontal direction and faces from the outside to the central part, is applied. This magnetic force generates the flow 10 of magnetic convection, facing toward the central part from the outside in the liquid, and the flow 10 cancels the flow 1 of the natural convection at the central part, thereby the natural convection is suppressed. Or when natural convection such that the liquid flows toward the lower direction at the central part of the liquid occurs, a magnetic force facing toward the outside from the central part is applied to suppress the natural convection.  The gradient magnetic field can be formed by using a gradient magnetic field generating device equipped with a permanent magnet, an electromagnet, a superconducting magnet or the like.
