Title: Signal transmitter
Inventor: SUEHIRO YOSHIKAZU
IPC: H04L25/38
Filed: 1987-09-11
Abstract: PURPOSE:To expand the number of optical transmission bits without expanding a signal transmission scale by providing plural signal transmission sections to apply time division multiple, using one of them as a master station and the others as slave stations and allowing the master station to send plurally the transmission signal of the slave station. CONSTITUTION:The first half of a start bit is set as '0s' and the latter half is set as '1s' to double the transmission speed to be distinguished from data. Moreover, a signal transmission section 11a (master station) multiplexes further the multiplex signal subjected to parallel serial conversion once. The start bit of the slave station has '0s' at the first half and '1s' as the latter half differently, then the first half start bits 33, 34 are taken in by the master station 11a and sends them. Thus, the same data of data bits are sent twice.

Filed: 1987-09-11
Abstract: PURPOSE:To obtain a high output slab type solid state laser device having less optical distortion by cooling a whole laser medium with the same flowing refrigerant. CONSTITUTION:In a laser having a laser medium 1 of substantially rectangular section including two optically smooth surfaces, in which a laser beam 7 is reciprocated while the beam is internally totally reflected plural times on the smooth surfaces, the whole laser medium 1 is cooled by the same flowing liquid refrigerant 9. For example, a window 20 is composed of a base material having the same refractive index as that of the laser medium, and the beam 7 is incident to the medium 1 and the window 20 at a Brewster angle theta determined by the refractive indices n2 and n2 of the refrigerant 9 and the medium 1 so that the longitudinal end face 1a of the medium is disposed in parallel with the window 20. Thus, since the medium 1 is cooled on the whole periphery uniformly by the refrigerant 9, temperature difference in the medium is minimized, and a high output laser radiation having less optical distortion is obtained.

Title: Method of identifying frequency characteristics of electric power system
Inventor: AMANO ISAO
IPC: G01R29/00
Filed: 1999-08-16
Abstract: PROBLEM TO BE SOLVED: To remove the effect caused by the generating source of harmonic current as a disturbance at the time when the frequency characteristics of an electric power system is identified by treating the value obtained by dividing mutual spectral density by the self-spectral density of an identification signal as the identified value of frequency characteristics. SOLUTION: The phase of each sine wave signal that makes up an identification signal x(t) from an identification circuit 50 is injected into an electric power system 1b by being displaced by 2 π/n (rad) ('n' is a plural number) from the previous one. From the responses of the electric power system 1b based on these injected identification signals, the correlation functions of the responses to the identification signal x(t) are obtained to calculate mutual spectral density by performing the Fourier transform of the average of the addition of each correlation functions so obtained. The value obtained by dividing this mutual spectral density by the self-spectral density of the identification signals is treated as the identified value of the frequency characteristics. This method can prevent the occurrence of a resonance phenomenon and the like.

Title: Bit data transfer circuit
Inventor: KANEKAWA RYOJI
IPC: G06F7/76
Filed: 1989-09-04
Abstract: PURPOSE:To reduce the size of a bit data transfer circuit by shifting first the data on a 1st latch circuit via a barrel shifter to make a 2nd latch circuit latch the shifted data and then selecting the data on the 2nd latch circuit and the barrel shifter via a selector. CONSTITUTION:The data latched by a latch circuit 1 is first shifted in the optional direction via a barrel shifter 2 by an amount equal to an optional number of bits. The data on a latch circuit 3 and the shifter 2 are selected by a selector 4. Then the shifter 2 is actuated with the input data of the same amount as the data on the circuit 1. The input data on the selector 4 is required by an amount double as much as the data amount latched by the circuit 1. However the output data on the selector 4 needs an amount equal to the data latched by the circuit 1. As a result, a function equivalent to the conventional one can be attained with a smaller circuit size.

Filed: 1988-09-13
Abstract: PURPOSE:To eliminate such a sense of incongruity that it takes a long time to display external characters by reading patterns corresponding to indicated in-use character codes out of an external storage device before a user program makes a display request. CONSTITUTION:The application program 1 indicates the external character codes to be used and requests a display control part 2 to read external display patterns in a display memory 3. The display control part 2, therefore, reads the patterns corresponding to the indicated external character codes out of the external storage device 4 and stores them in the display memory 3, and the control part displays internal characters first when receiving a display request by an application program and displays external characters by referring to the display memory 3 without accessing the external storage device when there are the external characters present. Consequently, an external display control part can displays the external characters by referring to the display memory without accessing the external storage device.

Filed: 1986-09-29
Abstract: PURPOSE:To use a data buffer also to store the status information by adding a bit showing an end state to the status information on a reception data block and writing said bit after the final word. CONSTITUTION:When two variable length data blocks A and B are successively received, data are written to an FIFO buffer 14. Thus data can be outputted from the buffer 14 and therefore an output enable signal 28 is outputted to a control part 43. Thus the part 43 applies the read control to the buffer 14 via a control line 26. As a result, the word data and an end state bit added to said word data are read out for check of a logical state of the end state bit. When logic '1' is judged, the part 43 judges the end state bit and the word data read out onto a data line 29 as the status information and writes them.
