Title: Semiconductor device
Inventor: GOTO KOJI
IPC: H01L29/78
Filed: 1990-02-16
Abstract: PURPOSE:To prevent influence of a noise current flowing through an N-type substrate to a transistor by surrounding a semiconductor device using the substrate with a P-type semiconductor layer, and surrounding a P-well with a semiconductor device using a P-type substrate with an N-type semiconductor layer. CONSTITUTION:When a P-type substrate 1a is used, a P-well 9 is surrounded by an N-type semiconductor layer 14. Accordingly, noise is transmitted from the substrate 1a to an N-well 4, but since noise transmitted from an N-channel transistor 3 to the substrate 1a is reduced by the layer 14, a noise current flowing to the substrate 1 is reduced. If an N-type substrate 1b is used, the well 4 is surrounded by a P-type semiconductor layer 15. Accordingly, noise from the substrate 1b to the well 4 is reduced, and no noise current flows from the substrate 1b to the well 9. Thus, both P-channel and N-channel transistors 2 and 3 are scarcely affected by the influence of noise.

IPC: G01S13/24
Filed: 1980-03-22
Abstract: PURPOSE:To simplify the construction employing a VCO serving both for transmission and local reception of signals by making IF to be a diffrence in the frequency  oscillated between the times for transmitting and receiving it. CONSTITUTION:Signals S1 and S2 having a fixed voltage difference V1 including sinewave and triangular wave are applied to sample hold circuits 2 and 3 from an oscillator 1 where a sample holding is made at a cycle T1 of a timing signal from a control circuit 5. The output signal of the circuits 2 and 3 is introduced to a change-over circuit 4 and fed to a VCO7 as a control signal with a switching to transmitting or receiving it. With such an arrangement, the difference in the frequency oscillated by the VCO between the times for transmitting and receiving it becomes a center frequency of IFA11. This allows the VCO to be used in common for a transmitting oscillator and a receiving local oscillator.

Title: Write control system of journal record
Inventor: TERAO MINORU
IPC: G06F12/00
Filed: 1986-02-21
Abstract: PURPOSE:To reduce the number of times of write to a journal file to improve the use efficiency of a file space by providing a journal record forced write means, a journal output request waiting detection means, etc. CONSTITUTION:In case of the write control of a journal record, a journal record forced write means 4 operates a journal output request waiting detection means 8 to inquire whether the journal output request from another file processing program is sent or not. If the journal output request is sent, forced write is delayed, and the means 4 reports the delay state to a blocking means 3 and returns the control to the file processing program. When the delay state is reported to the means 3, the means 3 inquires of the means 8 each time when the journal output request processing is completed, and the means 3 operates the means 5 if there are no succeeding journal output requests. Thus, the number of times of write to the journal file is reduced to improve the use efficiency of the file space.

Title: Decoding device
Inventor: REONARUDASU MARIA HENDORIKASU
IPC: G06F11/10
Filed: 1985-02-28
Abstract: A decoding device for code words which are protected against the occurrence of several symbol errors per code word by means of a Reed-Solomon code is provided with a word buffer which comprises a space for the storage of an erasure indication per symbol received. For correction of the code word, first the syndrome symbols are formed by multiplication by the parity check matrix. The sum of twice the number of error symbols and once the number of erasure symbols may not be larger than the number of syndrome symbols. First the syndrome symbols are modified so that the syndrome symbols which could possibly relate to error symbols (non-erasure symbols) are no longer influenced by the erasure symbols. The key equation and error locator equation for the non-influenced syndrome symbols can then be separately solved, so that the locations of error symbols can be found. The latter syndrome symbols are then modified, when necessary, for calculated error locations, while the error values or erasure values are determined from a set of mutually independent syndrome symbols whose numer equals the sum of error symbols and erasure symbols. There is provided an arithmetic unit for the Galois-field which, for the sake of simplicity, performs the calculations on the exponents of the symbols which are written as powers of the basic symbol of the Galois-field.

Title: Damping construction of building
Inventor: OMIKA YUKIHIRO
IPC: E04H9/02
Filed: 1996-02-26
Abstract: PROBLEM TO BE SOLVED: To facilitate execution in a minimized installation place by combining three to four planes of structure including a plane of structure incorporating a damper therein, forming a unitized self-supporting damping solid frame install it from the outside of a building. SOLUTION: A damping solid frame 1 is unitized by combining three planes of structure including a plane of structure incorporating a viscous damper 3 as a damper therein. In that case, the viscous damper 3 is incorporated so as to connect between a brace 5 and a column. When a building 2 is vibrated in the horizontal direction in case of an earthquake, seismic force is transferred to the outside damping solid frame 1 from the floor 2a of the building 2, and relative velocity occurs between layers of the damping solid frame 1. Damping force occurs from the damper in opposition to the displacement, and the force acts on the floor 2a of the building 2 to reduce the vibration of the building.  By the constitution, the damping solid frame 1 is an independent frame installed from the outside, selective flexibility of an installation place is extensive because it can be installed even in out of the plane of structure, and execution can be carried out in the minimized installation place.
