Title: Guided missile
Inventor: WATANABE YOSHIKO
IPC: B64C3/38
Filed: 1988-12-15
Abstract: PURPOSE:To improve response of a body, to simultaneously steer two types of steering wings of front and rear wings by a control signal of one controller to actuators of the two types of steering wings of the front and rear wings and to obtain advantages of both a front wing steering system and a rear wing steering system by forward moving a main wing after a rocket motor is burned. CONSTITUTION:A guided missile has two types of a front wing 2 forward of a main wing 3 and a rear wing 4 rearward of the main wing. The wings receive a control signal from one controller 5 to steer by operating simultaneously the actuators of the wings. When the main wing is moved forward, the force applying point of the body is moved forward, the long distance between the center of gravity and the force applying point can be shortened upon burning of a rocket motor to reduce static stability, thereby improving body response. Since the two types of steering wings 2, 4 are simultaneously steered by one controller, the advantages of both of the fast response of a front wing steering system and the high trim angle of a rear wing steering system are obtained to improve the performance of the guided missile.

Title: Packet exchange and packet exchange system
Inventor: SAGARA KAZUHIKO
IPC: H04B10/54
Filed: 1998-11-09
Abstract: PROBLEM TO BE SOLVED: To easily obtain data multiplexing between input and output ports even when the scale of a packet exchange is expanded by arranging encoders in a line interface part and multiplexing data by using a spread spectrum system. SOLUTION: This packet exchange 80 decides the destination of an upper IP frame by retrieving a routing table 30 and transfers the IP frame to optical output lines 91 to 9n and optical input lines 101 to 10n by a routing processor(RP) and forwarding engines(FE) 61 to 6n. Encoders 71 to 7n generate a scramble signal by multiplying a digital signal (baseband signal) by a random number of a specific cycle. Because the cycle of the random number can be designated by a specified code, ports can be recognized by allocating a different code to every line interface(LIF) 51 to 5n. Because an encoded code is decided by the cycle of a random number in this way, there is no constraint in a device, and multiplexing can be easily realized even when the number of ports is increased.

Title: Semiconductor memory
Inventor: ONODERA TADASHI
IPC: G11C11/401
Filed: 1999-11-08
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor memory in which an adjacent banks sharing a sense amplifier are not activated simultaneously even when a bank to be activated is erroneously specified or a power source is applied. SOLUTION: Banks B0-B2 are operated independently, for example, a bank B1 shares a train of sense amplifiers 3-01, 3-12 with adjacent banks B0, B2. When a bank enable-signal generating circuit 10-1 generates a bank enable-signal BE1 for activating the bank B1, the circuit 10-1 validates a bank enable-signal BE1 only when neither of adjacent banks B0, B2 are activated. A row decoder 1-1 and a control circuit 11-1 validate the sense amplifier enable-signal SE1 for activating word lines WL1, and the train of sense amplifiers 3-01, 3-12, a pre-charge signal PDL1 for activating pre-charge circuits 2-1a, 1-1b, and a switch control signal TG1 for controlling a conduction state of switches 5-1a, 5-1b only when the bank enable-signal BE1 is valid.

Filed: 1990-11-26
Abstract: PURPOSE:To make it possible to correct the flatness of a rail surface and provide a suitable crown shape to said rail surface by holding a magnetic head slider, using an offset portion and lap-finishing the surface of the rail. CONSTITUTION:A 20 mum or deeper groove 5 is formed on a block 4 where a row of magnetic heads 3 are laid out, using a mechanical means where the groove 5 will serve as an offset latter. All surfaces except for a rail are cut by an ion mill or a laser process, thereby forming a rail 2. The rail 2 is further cut so that it may be a magnetic head slider 1 respectively. An offset section 6 is supported with a support board 7. Then, the surface of the rail 2 is lapped by means of a lapping level block in such a manner that the rear section may be depressed by way of a flexible material, such as rubber. Since lapping is carried out with the offset section 6 supported, it is possible to correct the flatness of the rail surface 2. Furthermore, the rear section of the magnetic head slider 1 is lapped being pressed by the flexible material, the peripheral part is more lapped than the central part, which turns the rail surface 2 in crown shape.
