Title: Orbit control method for spacecraft
Inventor: FURUYA MASATOSHI
IPC: G05D1/10
Filed: 1992-11-05
Abstract: PURPOSE:To ensure robust stability relating to an modeling error, disturbance, noise and a target value change. CONSTITUTION:A control system is modeled by a generalized plant 100, control gain 110 and a virtual gain 120. In an input side of the generalized plant, a control input 11, target value 12 and external signals 21, 22 are set, and in an output side, controlled amounts 31, 32 and a measured value 41 are set. The control gain 110 is obtained so that an Hinfinity  norm of transfer function matrix from the external signal of a closed loop system to the controlled amount is less than 1 and further to ensure internal stability. Here, the virtual gain is a gain for reltaing the target value and the measured value to a linear shape obtained by assuming the target value, obtained by a fuzzy inference, as that guided by the measured value.

Filed: 1992-11-06
Abstract: PURPOSE:To obtain a semiconductor device which has an excellent heat dissipation, easy assembling and a small number of components by fixing three or more semiconductor elements to a common conductive board. CONSTITUTION:Lower surface electrodes of silicon surge absorber chips 1, 2, 3 are fixed to a copper board 5 via solders, and heads of bandlike leads 11, 12, 13 of a lead frame 10 are soldered to the upper surface electrodes of the respective chips.

Then, since the leads 11, 12, 13 are flat, they can be freely bent to be externally connected. Accordingly, heat conduction to a cooler 6 can be improved, the number of components can be reduced from six of prior art to two, assembling is made easy and a semiconductor device having high reliability can be obtained.

Title: Key storage system for data secrecy and data signature and security module provided with key storage function
Inventor: AKIYAMA RYOTA
IPC: G06F21/34
Filed: 1995-11-15
Abstract: PROBLEM TO BE SOLVED: To mitigate the congestion state of a line by providing the key managing table needed for secrecy, authentication and signature in the security module (the card) of a user side. SOLUTION: At the time of pulling out data from a data file 2, a verification request is transmitted to a card 4 and also a data delivering request is transmitted to the data file 2 from a work station 3. In the case an objective key is not stored in a key managing table, the card 4 receives the key from a key managing means 1 to store it in the vacant area of the key managing table (in the case the vacant area is not present in the table, the area of a low priority order is eliminated). When the data file 2 receives the data delivering request, the file 2 transmits the request data added with identifier to the card 4. When the card 4 receives the request data, the card 4 performs a signature verification processing by the key stored in the key managing table and generates a Y/N message to return it to the file 2.  Moreover, in the case of performing a secrecy communication processing, the card 4 uses the key stored in the key managing table similarly in the case mentioned above.

Filed: 1990-11-01
Abstract: PURPOSE:To always use the entire area of a picture display section independently of the aspect ratio even when an input signal with the different aspect ratio is applied to the display section and to obtain a beautiful picture with less deterioration in resolution by providing a plane mirror to the display device in a way that the plane mirror can be saved from an optical axis connecting a projection lens and an anamorphic lens. CONSTITUTION:The display device is provided with an anamorphic lens 21 and a plane mirror 16 placed between a projection lands 13 and an anomorphic lens 21 provided to the light emission side of the projection lens 13 and the plane mirror 16 is placed in a way that it is able to be saved from an optical axis connecting the projection lens 13 and the anamorphic lens 21. For example, when a signal whose aspect ratio is 9:16 is inputted to a display section 9 whose aspect ratio is 3:4, a signal processing circuit 11 able to convert the aspect ratio is used to compress the signal in the lateral direction thereby converting the aspect ratio of the signal into 3:4 and the result is displayed. The projection image is restored to 9: 16 being a substantial aspect ratio by operating the plane mirror 16 so as to lead the picture to the anamorphic lens 21 via the projection lends 13. Thus, the entire area of the picture display section is used to obtain a beautiful projection image without degrading the resolution of the picture display device.

Filed: 1988-11-25
Abstract: PURPOSE:To make the dispersion of load small and stabilize contact pressure at an on-time by forming a taper plan to be rectangular to an axial direction of a contact pressing spring at an off-time in almost half side position of a spring washer of a movable body responding to the movable contact wide. CONSTITUTION:A taper plan 131 being in a rectangular direction to an axial direction of a contact pressing spring 28 at an off-time is formed in an almost half side of a spring washer 130 of a movable body responding to a movable contact point 36. Then, the elastically contacting plan of the contact pressing spring 28 and the taper plan are set to be in parallel each other. The deflection degrees in right and left sides of the contact pressing spring 28 thus become almost the same and the contact pressing spring 28 becomes difficult to be detached from a hole 26c of a sequential plate 26. Also, the elastically contacting plan of the contact pressing spring 28 and the spring washer become in parallel at an on-time, and at both on- and off-time of a movable contactor 27, the contact pressing spring 28 becomes in parallel to the spring washer 130, therefore, dispersion of load becomes small and stabilized. As a result, contact pressing pressure at an on-time is stabilized and detaching of the contact pressing spring 28 at an off-time is prevented.
