Filed: 1990-06-14
Abstract: PURPOSE:To attain optimum AGC(automatic gain control) automatically even in the case of long or short range transmission by providing an equalization amplifier means, a gain control amplifier means and a control means. CONSTITUTION:In the case of long distance optical transmission, gain control amplifier means 221, 222 control the gain of a photoelectric conversion means 201, 202 and an equalization amplifier means 21 with a control voltage in response to an output level of the equalization amplifier means 21 to form 2 system of AGC loops. On the other hand, in the case of short distance optical transmission, a control means 23 inactivate the means 202 in the means 201, 202 to activate only one system in the 2 system of AGC loops. Thus, in the case of short distance optical transmission, the AGC loop of one system only is formed automatically and optimum AGC is applied to the system without deviation of AGC dynamic range. Thus, optimum AGC is applied automatically even in any of the long or short range transmission.

Title: Printing paper and its production
Inventor: NAGATSUKA FUJIYA
IPC: B32B27/36
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To make it possible to print characters and graphics on the surface of a plastic film with a printing machine or copying machine of an electrostatic copying type. SOLUTION: The surface of the plastic film 2 consisting essentially of polyethylene terephthalate is printed and coated with a coating material 1 which is prepd. by mixing and dispersing a pigment and a thermosetting resin having a curing temp. of 220 to 320 deg.C with and in an org. solvent, and is used as ink. The film is then dried at a temp. lower than the curing temp. of the thermosetting resin. As a result, the nature of the plastic film 2 is effectively utilized as it is and carbon particles are included therein by the coating material and, therefore, the film does not change even if the film is wet with water. The printed characters and graphics are hardly erasable even if the film is rubbed. The paper which withstands long-term preservation is thus inexpensively obtd.

Title: Control method of servo controller
Inventor: ARIMOTO TAKU
IPC: B25J13/00
Filed: 1984-07-24
Abstract: PURPOSE:To improve the tracking performance by changing an input signal within an input limit and using the input signal changed whose integration valve is unchanged so as to control a controlled system. CONSTITUTION:An input limit discriminator 10 discriminates whether an input signal u2 at a time (i) exceeds an input limit value UL of a servo controller and a controlled system or not. When the input signal in an input change arithmetic unit 11 exceeds the input limit value, an input limit value is outputted at the time (i) and when the changed input value u2 exceeds the input limit value, the input signal integration value to be changed is changed so as to be coincident with the integration value of the calculated input signal in a way adding the excess to a value at a time (i+2). On the other hand, if the input signal calculated at the time (i) does not exceed the input limit value, the result is outputted without any modification. In giving this input signal to the controlled system 6, an output signal nearly close to an object output signal is obtained.

Filed: 1981-10-02
Abstract: PURPOSE:To shorten an execution time of an SS format instruction, by reading out the following operand before writing a result, and overlapping write of the result and the following processing in time. CONSTITUTION:At first, both operands are read out and an ALU operation is executed. In this case, a result can be written by the first operand byte pointer FBP=0, but before executing it, read-out of the first operand of the second time is executed. At this point of time, data required for executing the ALU operation are collected in both the first operand register and the second operand register, and the ALU operation is restarted. Write of the result by FBP=0 is executed by keeping pace with this ALU operation, and 6 cycles are required in the same way as the ALU operation. When the ALU operation ends, an unprocessed byte number register goes to zero and the result is written. Total 20 cycles are necessary cycles.
