IPC: H04J13/00
Filed: 1999-04-27
Abstract: PROBLEM TO BE SOLVED: To enhance reception performance by detecting an accurate path timing, even with respect to a user signal whose reception electric field strength is weak. SOLUTION: Path search sections 41-4N output a path timing obtained by path-searching a received signal rin as a primary path timing signal 8, interference estimate units IEUs 11-1N in a 1st stage apply inverse spread processing or the like to the received signal rin on the basis of the primary path timing signal 8, so as to produce a symbol replica signal 51 and a tip replica signal 6, and a sbutractor 31 subtracts a sum of the chip replica signals 6 from the received signal rin to obtain a residual signal 7. The path search sections 41-4N use the residual signal 7 to conduct path searching again and output a timing of a path, whose time difference is within the range of a threshold with respect to a path with a deteriorated SIR as a secondary path timing signal 9.  IEUs 11-1N of 2nd and succeeding stages use the secondary path timing signal 9 to conduct processing, such as inverse spread processing.

Title: Information processor
Inventor: IGARASHI HIROO
IPC: G06F21/31
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To protect the security of a personal computer by means a password without starting a note-type personal computer main body by providing a means for opening a lock by means of inputting a correct password when the lock is fastened in a state where a cover is closed. SOLUTION: When the password is normally inputted by a password input key 5, a password input part 4 holds the password in a password backup area, transmits a message to fasten the lock to an LCD opening/closing lock part 3 and sets the lock. When the password input part 4 judges that the LCD opening/closing switch 2 is depressed, it displays a password input request to a password display part 6 and inputs the password by the password input key 5, reads the password which is inputted previous time and collates it with the inputted password. When the password is normal, the opening of the lock is transmitted to the LCD opening/closing lock part 3 and the lock is opened.

Title: Television tuner
Inventor: YAMAMOTO MASAKI
IPC: H04N5/44
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To prevent a navigation system from receiving interference due to higher harmonics of a local oscillation signal that is generated from a local oscillator by providing an attenuating means, which attenuates signals of a frequency that is higher than the highest frequency of a received television signal, between an input terminal and an input tuning circuit. SOLUTION: A television tuner 1 is equipped with a input terminal 18, input turning circuits 12 and 15 and local oscillators 5 and 8, and is further provided with an attenuating means 2 which attenuates signals of a frequency that is higher than the highest frequency of a received television signal. This prevents higher harmonics of a local oscillation signal of the tuner 1 from externally leaking from the terminal 18 and as a result, a receiver of a navigation system incorporating the tuner 1 no longer receives interference through higher harmonics of the local oscillation signal. Also, since the means 2 is provided between the terminal 18 and the circuits 12 and 15, it can simply be constructed only by adding the means 2 to a conventional television tuner 1.

Patent JP-S5019284-A (JP)
IPC: G02B6/42
Filed: 1973-10-29
Abstract: An apparatus for illuminating an operating zone which is observed by means of an observation mirror of the type having a stem, includes a light-generating device from which the light is transmitted to the operating zone over a light conductor and reflecting means separate from the observation mirror. The light-generating means comprises a light source which is positioned in one focal point of a cold-light reflector which is part of an ellipsoid. A planar cold-light mirror is provided between said focal point and the other focal point of the ellipsoid and makes an angle with the axis of the ellipsoid such that the visible light is reflected toward a secondary focal point positioned outside the maximum focusing cone of the reflector, one end of the light conductor being disposed at the secondary focal point. The other end of the light conductor cooperates with the reflecting means the surface of which makes an angle with the longitudinal direction of the stem of the observation mirror such that the light coming from the reflecting means strikes the operating zone. The latter angle is so selected in relation to the angle of the observation mirror to the longitudinal direction of the stem that the operating area becomes visible in the observation mirror.

Filed: 1987-05-19
Abstract: PURPOSE:To obtain a stable quality, by constituting a wall surface, containing a thinning edge in a thinning part, of tilt surfaces in plural stages so that a crossing part prevents the generation of chipping and the separation of cutting chips with the thinning part being easily machined. CONSTITUTION:A drill changes a radial angle in stages from a thinning edge 17a to a thinning edge 17b and from the thinning edge 17b to a cutting edge 12, and each crossing part of these edges forms a large obtuse angle. Accordingly, the generation of chipping and the separation of cutting chips in the crossing part can be prevented. While the drill, enabling tilt surfaces 16a, 16b to be easily formed by machine work, enables the stable quality to be attained. Further the drill, which forms the tilt surface 16b in the peripheral side into a spiral curved surface along a twist groove 13, generates no change of length of the thinning edge 17b in the peripheral side and its rake angle even if a flank 11 is polished. Accordingly, the drill, when it is repolished, is required for polishing only a bottom surface 15 of a thinning part 14, enabling the repolishing to be easily performed.
