Title: Stealth fighter
Inventor: KATONO SATORU
IPC: B64D47/08
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a stealth fighter which is difficult to be discovered and difficult to be attacked by an enemy fighter by covering a whole fighter body with cathode ray tubes, and fitting cameras thereon. SOLUTION: A camera 2 is provided on a tip part of a cathode ray tube body 1 in a stealth fighter. By projecting the image around the fighter which is picked up by the camera 2 on the cathode ray tube body 1, the body of the fighter is same in color as the scene therearound, and can not be identified, and the fighter body can be concealed. Since the whole fighter body is covered with the cathode ray tubes, the body is same in color as the scene therearound whose image is picked up by the cameras, and the position of the fighter can not be identified, the fighter body can not be visually identified. As a result, a pilot of an enemy fighter can not discover the stealth fighter body, and the stealth fighter is not be attacked. The cathode ray tube bodies and cameras can be applied to a tank, a warship, an aircraft carrier, a military helicopter and a submarine.

Title: Method and apparatus for diagnosing abnormality of current detector
Inventor: TABEI KUNIO
IPC: G01R31/00
Filed: 1987-09-29
Abstract: PURPOSE:To easily discriminate whether abnormality is generated in a current detector or in a control system, by calculating a current response speed value from the ratios of the present and previous measured values of the output of the current detector with a rated current value and judging the abnormality of the current detector when said ratios exceed upper and lower limit values. CONSTITUTION:The current signal (i) outputted from an insulation type amplifier 6 is sampled at a unit time cycle by a sampling means 71 to be stored. Then, the difference between the present measured value (in) and the previous measured value (in-1) is operated by the first operation means 72. Next, the ratio of said difference and the rated current value iC of a manual setting device 8 is operated by the second operation means 73 to hourly calculate a current response speed. This current response speed is compared with the upper and lower limit values in a normal range and, when it is judged that said response speed exceeds the upper and lower limit values, it is judged that a current detector 5 is abnormal.

Title: Lead-acid battery
Inventor: TOKUNAGA AKIO
IPC: H01M10/12
Filed: 1989-09-19
Abstract: PURPOSE:To prevent corrosion of a negative electrode plate ear portion and reduce the weight of a lead acid battery and enhance the performance and safety of the battery by retaining the negative electrode plate ear portion in a non-fluidized electrolyte. CONSTITUTION:The lower faces 2, 2' of straps 1, 1' to which groups of positive and negative electrode plates are welded are not in contact with the upper edge 4 of a liquid-retaining separator 3. After an element is inserted into a batter jar, powder of silicon dioxide is added until the upper portion of each strap 1, 1' is covered thereby, and then a dilute sulfuric acid is injected into the battery jar and the battery jar is charged, whereby a battery A is fabricated. Thus the section near the negative electrode ear portion is covered after the battery is charged, and the negative electrode plate ear 5 above the upper edge of the separator is covered with powder 6 of silicon dioxide containing an electrolytic solution. Thus a lightweight, high-performance lead-acid battery is obtained while its maintenance is totally unnecessary and corrosion seldom occurs in the negative electrode plate ear portion.

Abstract: PURPOSE:To facilitate the checking work of the bonding status by a method wherein, within an inner lead bonding device connecting an electrode of a semiconductor chip to a lead of a carrier tape, a punching means to arbitrarily punch out the part of carrier tape fixing a semiconductor chip is provided. CONSTITUTION:When one semiconductor chip 5 arbitrarily selected from those fixed on a carrier tape 2 in transit is aligned between a punch 11 and a dies 16 to drive an air cylinder 12, the punch 11 interlocked with a piston 13 is lowered. The carrier tape 2 held between the punch 11 and the dies 16 is punched out almost circularly with the semiconductor chip 5 aligned with the central part of the punch 11. Consequently, within an inner lead bonding device in such a constitution, the arbitrary semiconductor chip after finishing the inner bonding process can be punched out by the punch 11 and the dies 16 without interrupting the inner lead bonding process being performed this side in transit. Through these procedures, the checking work of the bonding status can be performed easily within a short time.

Abstract: PURPOSE: To rapidly and precisely inspect an inside surface in a small diameter of a work by holding an image to be made incident through a trapezoid prism in the same direction to a CCD camera. CONSTITUTION: When an inside surface image is photographed successively while rotating a detection head in the inspected inner wall surface 9 of the work 8, the inner surface image is turned and photographed by the CCD camera 19 when the CCD camera 19 is not turned. Then, when the trapezoid prism 29 is interposed and is turned by a drive mechanism 21 at a 1/2 angle of the rotational angle of the detection head 1, all of the images to be made incident on the CCD camera 19 are made incident in the same direction.  That is, since the detection head 1 and the trapezoid prism 9 are rotated at a prescribed rotation ratio, it is unnecessitated that the heavy-weight members such as the CCD camera 19 and a lends group 28 are rotated, and the images to be made incident on the CCD camera 19 are obtained in the same direction, thereby improving the precision of the inside surface image obtained by the immovable CCD camera 19.

IPC: H04B1/38
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To reduce noise caused by high frequency energy, transmitted via a telephone set harness by forming curl-shape nonlinear parts in the telephone set harness at intervals corresponding to the wavelength of communication radio waves. SOLUTION: Curl-shape nonlinear parts 116x which spirally wound the telephone set harness 116 are formed at the positions of distances L1, L2, L3,..., Ln from the end part of a connector part 116x in the telephone set harness 116. Thus, high frequency energy from the portable telephone set is rotated spirally by the curl-shape nonlinear part 116x. At that time, phases are mutually compensated and are attenuated. The formation position Ln of the curl-shape nonlinear part 116x is set to be integral number of times the 1/4 of the radio wavelength λ of the portable telephone set, which is most effective for the cancellation of the phases. Consequently, the occurrence of noise sound is prevented from a loudspeaker, and sound signal with low noise can be transmitted to a call opposite party by installing the nonlinear part in the harness.

Abstract: PURPOSE:To provide a scroll type hydraulic machine that prevents any possible wear between the peripheral wall of a fixed scroll and the end plate of a tuning scroll in time of low frequency operation. CONSTITUTION:An oil groove 43 is formed on a thrust surface 40a of a thrust plate 40, and when a turning radius of this oil groove 43 is set to delta, the whole thrust surface 40a is installed so as to be within a distance of 2 delta from the oil groove 43.
