Title: Method for coating fine particles by using supercritical fluid, and coated material
Inventor: MISHIMA KENJI
IPC: C23C22/00
Filed: 1997-08-05
Abstract: PROBLEM TO BE SOLVED: To obtain fine particles on which uniform coating film is formed with simple operation and gently in environment. SOLUTION: Liquid carbon dioxide fed from a cylinder 1 through a valve V-3 is sent to a preheating column 14 installed in a constant temperature water bath 18 and is heated to the equilibrium temperature of carbon dioxide and is turned into supercritical fluid and is sent to an extraction cell 15. In the extraction cell 15, PEG which is a high molecular compound which is a solute, ethanol which is assistant solvent for dissolving the high molecular compound in the supercritical carbon dioxide, and titanium oxide which is inorganic fine particles are completely dissolved bin the supercritical carbon dioxide which is solvent. Next, the supercritical carbon dioxide in which the solute is dissolved is introduced into a constant temperature air bath 23 through a heating pipe 19 when a stop valve V-6 is opened to jet it from a nozzle 20. In this way, the supercritical carbon dioxide is rapidly expanded and dissolving power of the solute is lowered. As a result, titanium oxide superfine particles 21 coated with PEG are collected by a panel 22.

Title: Lamp device for automobile
Inventor: SASAKI KENICHI
IPC: G01S15/08
Filed: 1990-08-23
Abstract: PURPOSE:To give sufficient brightness on road surface between a succeeding car and my car by providing a rear lighting lamp provided on the rear face part of my car, and lighting up the road surface in rear of my car in running or stopping condition. CONSTITUTION:On the road at night where several automobiles are running, when the succeeding car 4 in rear of my car 1 runs at the speed of 60km/h for example, the distance between my car and the succeeding car must be maintained at 75m. But because the illuminating range of the headlamp of the succeeding car 4 is 40m at low beam, there is possibility of running with the distance between cars at 40m, from the tendency of an automobile driver being fond of continuity of light. This is due to insufficient brightness of the road surface between a (b) point and a (d) point. Therefore, the road surface between the point (b) and the point (d) is illuminated with a rear lighting lamp 3 having center luminous intensity at a point (c) so as to insure continuity of light. Lighting of the rear lighting lamp 3 is controlled by a brightness detecting device.

Title: Fuel injection device for internal combustion engine
Inventor: ITO EIJI
IPC: F02M45/08
Filed: 1987-09-07
Abstract: PURPOSE:To enable to perform stable main fuel injection continuously after pilot fuel injection by forming the fuel inlet side end portion of a plunger larger in diameter than the fuel outlet side end portion and engaging the large diameter portion into the flow in chamber and still the small diameter portion into the flow out chamber respectively slidable. CONSTITUTION:During a period of main fuel injection, a small diameter portion 13 of a plunger 11 is pressed into the flow out chamber 17 deeper than during pilot fuel injection, therefore it becomes that fuel pressure in this flow out chamber 17 goes up. But, pressure receiving area of the small diameter portion 13 facing to this flow out chamber 17 is smaller than pressure receiving area of the large diameter portion 12 facing to the flow in chamber 15 therefore difference of press forces generated between up stream side and down stream side of the plunger 11 can be maintained as it is. Therefore, the plunger 11 can get along without pressing back to the fuel inlet port 9 side. Thereby, fuel can be led stably to a fuel injection valve 2 without intermittence in connection between the flow in chamber 15 and a connecting channel 26 during a period of main injection.

Filed: 1982-12-22
Abstract: PURPOSE:To enable a call charge to be informed to a caller by a telephone set used for the call by informing acoustically the call charge to the caller by the indication of the caller when a call is finished in a telephone exchange. CONSTITUTION:A central controller 8 starts the calculation of charging and transmits a call charge to a storage device 9 at each unit time. When the caller hooks on once a handset for the end of the call, the central controller 8 detects it via a scanner 6, stops charging and also stops the transfer of charge to the storage device 9. When the caller A1 hooks off again the handset after a prescribed time, the central controller 8 detects it via the scanner 6, the charging for the finished call's share just now of the caller A1 is read from the storage device, converted into voice at a voice synthesis output device 5 and the voice is informed to the caller A1 via a channel switch 2.

Title: Hybrid type speed change gear with internal gear and roller
Inventor: ISHIBASHI AKIRA
IPC: F16H37/02
Filed: 1986-09-24
Abstract: PURPOSE:To prevent variation in a speed ratio, by pressing taper rollers into contact one another under a pressing force using thrust produced to a skew gear to reduce slip on the contact surface of the rollers. CONSTITUTION:Taper rollers 6A, 6B, 6C, which are pressed into contact against a taper roller 4 of an input shaft 1, are disposed at respective ends of intermediate shafts 3A, 3B, 3C. The intermediate shafts 3A, 3B, 3C have another ends to which skew gears 7A, 7B, 7C to be meshed with a skew external gear 5 are disposed. With the arrangement, the taper roller 4 of the input shaft 1 is gripped by the three taper rollers 6A, 6B, 6C so that it is pressed into contact against the taper roller 6A, 6B, 6C of the intermediate shaft under an action of a load imposed in advance in a normal direction with respect to a contact surface. As a result, since the taper rollers are pressed into contact one another by thrust produced the skew gears under an action of a pressing force, excessive slip on the contact surface of then rollers is prevented, whereby no variation in a speed change ratio is caused.

Abstract: PURPOSE:To provide the arithmetic operation unit in which a general number and a fuzzy number are calculated collectively and efficiently. CONSTITUTION:Input data given to a buffer 11 for data 1 and a buffer 12 for data 2 (data 1, 2) are sent to a data class discrimination section 15, where the data are fuzzy data are discriminated. In this case, an arithmetic operation code added to the input data is outputted from an arithmetic operation code buffer 13 to an arithmetic operation section 20. When the data class discrimination section 15 discriminates the input data to be a fuzzy number, it is outputted to a fuzzy normalization arithmetic operation section 17 and when not, the data are outputted to a crisp normalization arithmetic operation 16. The normalizing arithmetic operation section normalizes the input data and outputs the normalized data to the arithmetic operation section 20 through a buffer 18 for after-normalizing data 1 and a buffer 19 for after-normalizing data 2. An arithmetic operation code is inputted to the arithmetic operation section 20 and the arithmetic operation is implemented based on the arithmetic operation code. The result of arithmetic operation by the arithmetic operation section 20 is stored in an output buffer 22.

Filed: 1986-09-22
Abstract: PURPOSE:To improve the lock-on probability by calculating the lock-on probability and deflecting an antenna to perform an angle searching action in the case of an inferior lock-on probability. CONSTITUTION:A lock-on probability calculation part 21 calculates the lock-on probability to lock on a target based on the target information and the mother device information received from a command receiver 17 and the inertia information on a controller M received from an inertia navigation device 8. If the calculated lock-on probability is low, an antenna servo controller 22 is driven for control of the searching range of antenna angles. Thus an antenna is deflected for change of its angle searching range. Then it is possible to improve the lock-on probability and to track and catch a target with a high shoot-down rate.
