Title: Multiplex wavelength optical amplifier
Inventor: MUKAI TAKAAKI
IPC: H01S3/063
Filed: 1981-11-05
Abstract: PURPOSE:To obtain the amplifier, which can directly amplify a light singal without photoelectric transducing action, can implement the amplification action by using one common element with respect to multiplex wavelength signal light, and has a compact, simple constitution. CONSTITUTION:Two facing reflecting surfaces 3 and 4 are providing in a single current injecting type semiconductor laser amplifier element 1. Light is inputted to one side and outputted from to other side. The reflecting surfaces 3 and 4 act as a half mirror. When a forward direction current is injected from a terminal 2, the element 1 starts laser oscillation at a certain current value or more. Under the bias state lower than this oscillation limit, the Fabry-P erot resonating type linear optical amplifier having a gain vs. frequency characterisic shown by a solid line is obtained. In this amplifier, each carrier wavelength of the incident multiplex wavelength signal light (f1...fN in frequency indication) is set so that it agrees with the frequency of a resonating point. When the multiplex wavelength signal light, whose carrier frequency is the frequency f1... or fN which is equal to the resonance frequency of the amplifier, is inputted into the resonating type optical amplifier 1, respective light is directly amplified, transmitted through the other reflecting surface 4, and taken out.

Inventor: MORITA TAKESHI
IPC: G06T7/00
Filed: 1986-07-28
Abstract: PURPOSE:To avoid the influence of variance caused by the noises or the change of the working environment by defining the R, G and B outputs obtained when the illumination of a color detector is turned off as the offset value to correct those outputs in a color dividing job mode. CONSTITUTION:The R, G and B outputs of a color sensor 24 of a color detector obtained when the illumination of the color detector is turned off are stored in a memory of a firmware CPU43 in the form of the offset value with a coordinate position defined as an address. This offset value stored in the memory are subtracted from the R, G and B detection outputs obtained by the sensor 24 for correction in the following dividing job mode. In such a way, it is possible to obtain the color dividing data of high accuracy that is free from variance due to the noises or the change of the working environment.

Title: Hologram interferometer
Inventor: TENJINBAYASHI KOUJI
IPC: G01B9/021
Filed: 1987-07-16
Abstract: PURPOSE:To achieve an accurate reproduction of an object light, by irradiating a hologram from the back of an object to be inspected in the measurement thereof after a reference light identical to that when the hologram is generated is reflected to be tilted by 90 deg. with a flat mirror. CONSTITUTION:A flat mirror 14 is arranged between a collimator lens 6 and a hologram 3. The flat mirror 14 turns the optical path of a reference light 15 as parallel light leaving the collimator lens 6 by 90 deg. to be incident into the hologram 3. In this manner, the hologram is lighted with a wavefront the same as that of the reference light 15 used when the hologram is generated. This corrects any astigmation in the reference light 15 thereby achieving an accurate reproduction of an object light (spherical wave). This eliminates the need for a non-spherical objective lens with a high accuracy thereby facilitating adjustment with a simple construction.

Title: Vicinal electrolytic apparatus for strip
Inventor: HINOTO HAJIME
IPC: C25D7/06
Filed: 1980-12-17
Abstract: PURPOSE: To make it possible to plate a strip rapidly with a large current, by jetting an electrolyte in close vicinity from curved electrodes divided in the circumferential direction of a roll to the surface of the strip passing along the circumferential surface of the rotating electric conducting roll to increase surface contact between the strip and roll.  
     CONSTITUTION: A rotating electric conducting roll 3 that is not dipped into an electrolyte has an electric conducting surface 12 narrower than the width of a strip in the central part of its surface layer and has its both ends sealed with a non-conductive material 13. A current flows through a contact surface between the surface 12 and strip 1. A hollw anode 4 closely opposite to the strip 1 passing along rolls 2, 3, and 2' is nearly parallel to the width direction of the strip and is curved in the longitudinal direction of the strip. If a plating liquid is supplied into the hollow part of anode 4, the liquid is jetted from a slit 5 in the direction of an arrow, and static pressure P is formed between the anode 4 and strip 1. Thus, contact surface pressure between the strip 1 and roll 3 is increased. Furter, if the anode 4 is insoluble, a gap between the anode 4 and strip 1 is maintained constant and thus the current density can be maintained stably.

Title: Multi-stage fluidized layer type reaction apparatus
Inventor: KOJIMA KENJI
IPC: B01J8/28
Filed: 1980-12-19
Abstract: PURPOSE:To provide the titled apparatus necessitating no auxiliary fluid for falling a powder and making a superficial velocity constant comprising opening particle falling pipes which pierce perforated partition plates of a fluidized layer divided into plural stages in a vertical direction and of which a lower end part is tapered above the lower perforated partition plate respectively. CONSTITUTION:An inside of a shaft shaped container 1 is divided into plural stages by perforated partition plates 5, 6, 7 and each stages are filled with a solid particle respectively to form a multi-stage fluidized layer. Through the partition plates 5, 6, particle falling pipes 11, 12 are respectively pierced and upper end surfaces thereof are fixed to said partition plates so as to be brought in line with surfaces thereof as well as other ends thereof are opposed to the lower partition plates 6, 7. In the above described constitution, if moving layers are respectively formed in insides of the pipes 11, 12 preliminarily by known means, a fluid superficial velocity of a fluid upwardly flowing through the insides of the pipes 11, 12 is made extremely low. Therefore, particles fluidized on upper surfaces of the pipes 11, 12 are fallen and particles of the fluidized layers 8, 9 can be respectively moved to the lower stage layers 9, 10. Because of increment pressure difference generated at both ends of the pipe 11, the fluid superficial velocity of the fluid raising through the inside of the pipe 11 is increased and resistance imparted to the falling fluid is increased and, therefore, a particle amount of the layer is returned to a steady condition.
