Title: Hybrid satellite communication system
Inventor: TOYONAGA NARUHITO
IPC: H04B7/15
Filed: 1987-02-09
Abstract: PURPOSE:To improve the activity efficiency of a satellite line, by using the satellite line for transmission from a station A to a station B, using a ground line for the transmission in a reverse direction, and operating an error correction function in a ground line system independently from a transmission procedure between both stations. CONSTITUTION:In packet transmission between the stations A and B, a packet (command) from the station A to the station B is transferred via a satellite 3, and the packet (response) from the station B to the station A is transferred via the ground line 20. The command and the response are transferred according to an X.25 transmission control procedure recommended by CCITT. In such a case, an error generated in the command is informed to the station A by the response, but, the correction of the error generated in the response is performed independently from the X.25 procedure between the stations A and B by using the error correction function in the system. In such a way, no error is generated in the response from the station B to the station A from the standpoint of the X.25 procedure, and also, most of delay time can be neglected compared with the command.

Title: Sample support for thermal balance
Inventor: SENDA TETSUYA
IPC: G01N5/04
Filed: 1986-02-12
Abstract: PURPOSE:To obtain a simple, small and inexpensive sample support apparatus,by mounting a sample on one arm of a thermal balance utilizing a magnetic reaction in the same polarity between two permanent magnets. CONSTITUTION:A repulsive force works between N poles and S poles of a cylindrical magnet 9 and a bar magnet 15. As a vertical component of the repulsive force acts as upward force like a vector (p) to the magnet 15 and a sample 17 and the like, the sample 17 or the like is mounted on an arm 2 of the balance by this force. The horizontal component of the repulsive force each between N poles and S poles acts radially in all directions within the horizontal plane, but if the magnet 15 should be biased to one side within the horizontal plane, the distance between the magnets 9 and 15 in this side is reduced to increase the repulsive force thereby automatically correcting the bias. As the arm 2 of the balance is tilted toward one direction, a light shielding plate 5 moves upward or downward to change the quantity of light incident into a photoelectric converter 7. Thus, the balance can be always automatically adjusted to maintain a balance by increasing or decreasing the output of an amplifier 8.

Title: Method and device for optical parallel processing
Inventor: HASHIMOTO HITOSHI
IPC: G02F3/00
Filed: 1988-02-08
Abstract: PURPOSE:To utilize the parallel property and the high speed property of light and to execute an optical parallel processing which can execute a multistage input and a multistage processing, and also, which is programmable by replacing the binary state of digital information with two polarizations intersecting orthogonally with each other, separating them so that there is no overlap in accordance with the polarization and selecting its light. CONSTITUTION:A light beam from a light source 1-1 becomes a linearly polarized light by a polarizer 1-2. The linearly polarized light is varied in the polarizing direction by an input signal 1-3 in a space modulator 1-3'. That is, in the binary state, at the time of one state, the polarized light rotates by 90 deg. and becomes a linearly polarized light in the vertical direction in parallel to the paper surface, and at the time of the other state, the polarized light is not varied and remains vertical to the paper surface, as it is. The light beam passing through the space modulator 1-3' is separated spatially in accordance with the polarized light by a double-refraction plate 1-4. In such a way, the light beam separated spatially in accordance with the state of the input signal 1-3 is selected to a carnel 1-5. Therefore, the result of processing can be obtained at the speed of light, and the processing speed is high. Also, parallel image information consisting of a large quantity of picture elements can be processed as it is in the state that the parallel property is high.

Title: Electric power control device
Inventor: YOSHIDA KEIZOU
IPC: H02M7/5387
Filed: 1980-03-04
Abstract: PURPOSE:To prevent damages to a transistor because of an overcurrent, by preventing an on/off control signal after detection by a detection circuit from being applied to a transistor base. CONSTITUTION:When a voltage of a resistor 17 is lower than the normal voltage a comparator 18 outputs a logic 1, and when higher it outputs a logic 0. And because the comparator 18 possesses a latching function, a state in which the output is 0 is retained after an output is changed 1-0. When an input current valve to a switch circuit 11 surpasses a corresponding valve of the normal voltage, an output from a pulse width modulation circuit 15 is prevented from being input to a base driving circuit 16 because of a gate circuit 19. Therefore all transistors 11-1-11-4 fall into a state of noncontinuity. Consequently by setting the normal voltage of a normal voltage generator 20 at a lower value than that corresponding to the maximum valve of the permissible current of the transistors 11-1-11-4, a flow of overcurrent to each transistor can preliminerily prevented.

Therefore, the metallic magnetic substance bodies 14 and 15 and glass 13 and 17 are firmly united in one body by mutual diffusion and the gap line becomes stable. Moreover, the tape sliding surface of this head is composed only of the magnetic substance and no wear of bonding agent exists and, therefore, reliability of this magnetic head is improved. In addition to the above, no unevenness in height occurs which results in a high accuracy.
