Title: Mutual backup method and routing method for a plurality of servers
Inventor: AITSU MASATO
IPC: G06F13/00
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To provide the mutual backup method for a plurality of servers by which the client server system with high reliability is realized at a low cost. SOLUTION: When a client requests update of data to a server A (access server), the server A inquires about a time stamp stored in all other servers B, C. Since the time stamp of the server A is To a time stamp reply from the servers R, C to the server A is To , the server A confirms it that data stored in the server A are not old. Moreover, a time T1 at this point of time is stored in the server A as the time stamp for updated data this time, and the server A makes data update request this time to the other servers B, C and distributes the time stamp T1 to them. The other servers B, C update the data and the time stamp similarly in the case of the server A. The server A receives data update reply from the other servers B, C and the data update reply is returned to the client.

Title: Liquid crystal display element
Inventor: NAKAGOME TAMIHITO
IPC: G02F1/13
Filed: 1986-10-08
Abstract: PURPOSE:To improve the contrast through prevention of the occurrence of domain phenomenon even when a twist angle is increased, by incorporating a particular compd. in a nematic liq. crystal in a liq. crystal display element comprising a liq. crystal molecule having a twisted structure. CONSTITUTION:A nematic liq. crystal having a positive dielectric anisotropy and containing an optically active substance added thereto is filled between a pair of upper and lower electrode substrates disposed opposite to each other to prepare a liq. display element in which a spiral structure having a twist angle of 200-270 deg. in the thicknesswise direction thereof is formed in the liq. crystal molecule. In the above process, 5-60wt% compd. having a structure of formula I (wherein m and n are each 1-7) is incorporated in the nematic liq. crystal. This causes the contrast ratio to be increased and therefore, prevents the occurrence of domain phenomenon even when the twist angle is increased. Thus, a high-quality display can be obtained even during high time sharing drive. Examples of the compd. of formula I include compds. of formulae II and III.

Title: Keyboard device
Inventor: TSURU MASAFUMI
IPC: G06F3/02
Filed: 1988-09-22
Abstract: PURPOSE:To reduce cost and to improve reliability by reloading a timer counted value in order to correct a disturbed scan interval according to a request which is asynchronously generated. CONSTITUTION:When a sub CPU2 finishes command processing and is restored before the generation of interruption, a terminal counted flag to be generated from a timer counter 4 is subjected to polling. Then, since the sub CPU2 is active, scan processing to be shown by ts1 is executed. In such a case, since a time to next scan activation is secured by setting the counted value corresponding to an interval time tit to the timer counter 4, an enough time to be needed for catering absorption is guaranteed as shown in a tsw2 (tit). Thus, since the catering absorption is executed by a software, the cost is reduced and the reliability is improved.

Title: Laminated soft magnetic film
Inventor: INAZUMI MITSUHIRO
IPC: H01F10/08
Filed: 1983-12-19
Abstract: PURPOSE:To obtain a magnetic thin film having excellent soft magnetic characteristics in a high frequency area by laminating vertically magnetized films. CONSTITUTION:In case a film 4 magnetized vertically and uniformly is put on a soft magnetic film 3, and magnetostatic energy of a magntic wall 5 is reduced due to a magnetic field given from the film 4. Therefore the number of magnetic walls can be increased. When the magnetization of the film 4 is inverted, the magnetic field applied to the film 3 becoms uneven. Thus more effective formation of magnetic walls can be expected. As a result, the number of magnetic walls of the film 3 can be increased owing to the lamination of both films 4 and 3. This improves the high frequency characteristics of a soft magnetic substance with no big increment of the hysteresis loss.

Abstract: PURPOSE: To reduce the loss of a light source and to obtain a bright projected picture by forming a reflector reflecting and condensing a light beam of a dichroic multi- layered film selecting and reflecting wavelength and using it as a light source for emitting the light beams having different wavelength in different directions. CONSTITUTION: Two or more reflectors 1-a and 1-b are formed of the dichroic multi- layered film selecting and reflecting the wavelength and used as the light source emitting the light beams having the different wavelength in the different directions by making the wavelength selecting characteristics of the respective reflectors 1-a and 1-b different. That means, the white light beam of a lamp 2 is reflected by the blue reflection dichroic reflector 1-a reflecting only a blue component. Besides, the green and the red light beams are condensed in the different directions and guided to a liquid crystal light valves 5 respectively modulating a green and a red components by the red and green reflection dichroic reflector 1-b reflecting the green and the red components. Then, the light beams are synthesized by a dichroic prism and projected on a screen 7 through a lens 6. Thus, a distance to the valve 5 from the lamp 2 is shortened and the loss of the light scattered and lost around is reduced. Besides, the bright projected picture is obtained.
