Patent JP-S6442608-A (JP)
Title: Method for connecting optical fibers
Inventor: SUGAWARA YASUYUKI
IPC: G02B6/24
Filed: 1987-08-10
Abstract: PURPOSE:To prevent the failure in connection by the influence of air bubbles by subjecting optical fibers to a pretreatment to crush the air bubbles by previous heating then welding and connecting the fibers. CONSTITUTION:The air bubbles 2 in the heated part are crushed when discharge electrodes 3 are set at the specified point from the terminal of the optical fiber 1 having the air bubbles 2 and the fiber is heated to melt by discharging electricity from the electrodes. The left side part of the heated part is confined in the fiber at this time but the part to be heated is just a part and since the volume of the air bubbles is larger than this part, the bubbles do not expand and burst. Since the right side is open, the bubbles in this part do not burst. The air bubble part is crushed by the force of surface tension and the solid glass is successively formed when the electrodes in the discharge state are moved to the right, i.e., toward the terminal. The optical fibers are welded and connected after the air bubbles therein are crushed to form the solid fibers in such a manner and, therefore, the increase in the transmission loss of the optical fibers by the influence of the air bubbles is prevented.

Title: Stepping motor
Inventor: MIYAZAWA HIROSHI
IPC: H02K37/14
Filed: 1992-07-03
Abstract: PURPOSE:To vary the magnetic resistance between stators in sets and enlarge the detent torque of a rotor at nonapplication of a current and stabilize it by varying the gaps between the stators and a casing, between the stators in sets, in a permanent magnet type of stepping motor. CONSTITUTION:Two sets of stators 3 and 4 are assembled out of circular stators 21, 22, 23, and 24 and coils 25 and 25, and magnetic poles 27, 28, 29, and 30 are formed at the inside periphery opposed to a rotor 2. For these magnetic poles 27, 28, 29, and 30, the inside peripheries of the respective stators 21, 22 and 23 and 24 are bent at right angles, and are opposed alternately to the N and S poles around the rotor 2, and the two sets of stators 3 and 4 are arranged, with their phase angles slid by pi/2. Here, magnetic resistance is increased by forming gaps 31 between the outside peripheries of the stators 23 and 24 and the inside periphery of a case 9. Accordingly, the detent torque generated in the rotor 2 becomes the torque caused by the stators 3 and 4 in sets.

Title: Airframe system
Inventor: MORITA MASASHI
IPC: F42B15/01
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To enable tracking of a target by a correlation processing of target reflected waves without being supported by a ground radar, by launching two airframes for one target and by executing the correlation processing of a target reflected signal between the airframes. SOLUTION: Two airframes 1 and 2 are launched for one target 3 and the airframe 1 casts a radio wave S1 on the target 3. The tracking radio wave S1 is reflected on the target 3 and the wave containing a Doppler component depending on the velocity of the target is received by both of the airframes 1 and 2. The airframe 2 transmits S4 a received target reflected wave S3 to the airframe 1. The target reflected wave S3 via the airframe 2 which is received by the airframe 1 contains a time delay depending on a route difference and a processing time in the airframe 2 and Doppler components of the target 3 and the airframe 2. In the airframe 1, a target reflected wave S2 received directly from the target 3 is correlated with the target reflected wave S3 received via the airframe 2, in a frequency region and a time region, and a target signal is thereby detected.

Abstract: PURPOSE:To permit an operator to know the generation of a trouble previously and to take a proper measure by repeating the try for advance/retreat gear shift several times and generating alarm when the desired gear shift is not generated. CONSTITUTION:The try operation in the gear shift of an advance/retreat gear is carried out, and after the lapse of a predetermined time, the output signal of the lever selection supplied from an advance/retreat lever position detection sensor 6 and the input signal of the gear shift position supplied from an advance/retreat gear position detecting sensor 5 are compared, and when both the signals accord, a clutch is connected, and the selection of the advance/retreat gear is completed. When the signal from the advance/retreat gear position detecting sensor 5 is other than a signal for advance, the try of gear shift is carried out again, and if the signal from the advance/retreat gear position detecting sensor 5 becomes a signal for advance during process of n-times of tries, the clutch is connected, and the selection of the advance/retreat gear is completed. When the signal of the advance/retreat gear position detecting sensor 5 is other than a signal for advance, even if try is repeated n-times, it is judged that the machine is in trouble, and a warning lamp 15 lights up.

Title: Container made of aluminum alloy
Inventor: FUJIMOTO TOSHIO
IPC: B65D8/04
Filed: 1999-07-14
Abstract: PROBLEM TO BE SOLVED: To improve the impact-fracture resistance by forming a container into a columnar body having a specified cross sectional shape, and specifying the thickness of the side surface, in the container made of an aluminum alloy which is widely used for a beverage can or the like for beer or a soft drink or the like. SOLUTION: In order to improve the impact-fracture resistance of this container made of an aluminum alloy, the cross sectional shape is formed into a circle to a polygonal shape. Especially, a cylindrical body with a polygonal cross sectional shape, is preferable, and the cross sectional shape preferably is an n-angled polygon (4<=n<=36) from a square to a 36 angled polygon. Then, this aluminum alloy container is made of an aluminum alloy while the thickness of the side surface is not more than 0.1 mm. By this container made of the aluminum alloy, when the container collides with other object due to, e.g. a fall, even if the container collides with the other object from the top-most vertices, the collision is quickly transferred to a contact with either one of the edges on both sides.  Therefore, a plastic distortion due to a stress of the collision is substantially applied to one edge of the polygonal shape while being dispersed. Thus, the impact-fracture resistance can be increased.
