Title: Optical amplifier control system
Inventor: KINOSHITA SUSUMU
IPC: H01S3/067
Filed: 1992-03-02
Abstract: PURPOSE:To constitute the above system in such a manner that automatic photooutput control (APC) is executed while the internally generated noises are kept low at wide input levels. CONSTITUTION:Stimulating light to put an Er-doped fiber 25 in an amplified state is kept maintained at the specified value sufficient for optical amplification by a stimulating light control circuit 31. The control of the light output level of the optical amplifier is executed by controlling the light attenuation quantity of a variable light attenuator 32 in accordance with the electric signal from a photodetector 29 for monitoring output light which receives a part of the output light from the variable light attenuator 32 and photoelectrically converts this light so as to suppress the fluctuation in the output light by a signal light output control circuit 33. Since the Er-doped fiber 25 is sufficiently excited, the naturally released light coefft. proportional to the noise electric power generated within the optical amplifier is kept always in the low state. The APC is thus realized with the low noise characteristic at the wide input levels.

Abstract: PURPOSE:To perform high-quality rolling by correcting the peripheral speed of rolling roll by the motor-speed setting system of the 1st rolling stand so that a tension obtained by a computing means coincides with a target tension. CONSTITUTION:Detection signals detected by load meters 15, 16, the rotating speeds of motors 8, 9 detected by speed detectors 10, 11, and the voltages and currents of motors 8, 9, are inputted to a processing unit 18.

The rolling load, the rolling torque, and the thickness of material, which are obtained based on respective input signals when the material is rolled only by the 1st stand, are previously stored. Next, when the material is rolled by the 1st and 2nd stands, the correcting value for correcting the peripheral speed of rolling roll is computed based on the stored values and each input signal, to correct the speed reference value of motor 8 by using the computed value as the speed correcting quantity of the 1st stand. In this way, the tensionless state of a material to be rolled is obtained.

Title: Ink jet recorder
Inventor: SHIMIZU MEGUMI
IPC: B41J2/205
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To improve recording quality by a method wherein density variation due to variation in volumes of ejected ink drops ejected from ink ejection nozzle provided in an end section of each head unit is reduced. SOLUTION: In a head, adjacent two head units 232, 233 are disposed such that parts of ink ejection nozzles at end sections thereof are superposed in a paper feeding direction. An image signal having eight gradation levels is inputted to a correction circuit 41 and a line direction position signal is inputted to a position signal judgment section 42. When it is judged that the image signal is in correspondence with the superposed ink ejection nozzles in each head unit, the gradation levels of the image signal is divided such that for example, seven levels are divided to six levels for one head unit and one level for the other head unit by using a look-up table in the correction circuit 41. Thus, one dot is formed by combining ink ejection from ink ejection nozzles on the two head units.

Then, when the cassette 1 is further pushed inside in the direction of an arrow A from the state of the cassette 1 that is just prior to abuting against the lid body 2, since the guide pin 2b of the lid body 2 is incapable of entering the guide groove 4a, the guide pin 2a is guided by the guide groove 4a to move in the direction of an arrow B so that the lid body 2 is opened. Afterward, the guide pin 2a is moved along the guide groove 4a in the direction of an arrow F, while the guide pin 2b along the guide groove 4b respectively so that the lid body 2 is closed. By this method, the miniaturization of the device can be contrived.

IPC: G02B6/126
Filed: 1997-02-13
Abstract: PROBLEM TO BE SOLVED: To obtain a communication speed similar to that of a single-mode fiber by using an inexpensive multimode fiber by arranging a specific hologram element at the photodetection-side exit of the multimode optical waveguide. SOLUTION: At the photodetection-side exit of the multimode optical waveguide which propagates the projection light from a laser used for optical communication, the hologram element is arranged which diffracts only light in specific propagation mode of the optical waveguide, and the travel direction of only the light in propagation mode is changed. Namely, the light 1-9 having its intensity modulated is coupled with the multimode fiber 1-3 from the laser 1-1 through a lens 1-2. When the distance of the fiber is long and signal modulation is fast, the output signal from the fiber is distorted because of repetition of modes. When, however, a mode separator 1-4 is used, an LP01 mode is diffracted upward and an LP11 mode is diffracted as a plane wave, so that the two mode can be separated and photodetected by using lenses 1-5 and 1-7 and photodetectors 1-6 and 1-8 respectively.
