Title: Light-emitting array apparatus, its manufacture, light- scanning apparatus, and image-forming apparatus
Inventor: SEKIYA TOSHIYUKI
IPC: B41J2/44
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To prevent a decrease of a setting workability when a commercially available resistance is used and prevent a change of an emission wavelength because of a difference of driving currents of chips in relation to a light-emitting apparatus used in an image-forming apparatus of an electrophotographic recording system, its manufacture, a light-scanning apparatus using the light-emitting array apparatus, and an image- forming apparatus using the light-emitting array apparatus. SOLUTION: An abscissa-coordinate value of an intersection between a line Lp of a required L target of an emission amount and a characteristic line C1-C15 of each chip is the reciprocal of an external current limit resistance value required for obtaining the emission amount of the L target by each chip. A coordinate value of the intersection of the characteristic line C1 of a first chip nearly agrees with a value of 1/R1. Coordinate values of intersections of the other chips do not agree with any of resistance inverse number values 1/R1-1/R11, and these intersections are within d1-d10 of an equal width. A resistance value range is divided on the basis of commercial resistance values of the normal 96 series in terms of R dimension, and a group of chips having intersections in the width d1-d10 are specified in one rank in terms of a quantity of light. Groups in the same rank are used for one apparatus.

Title: Decoding device and decoding method
Inventor: KATAYAMA HIROSHI
IPC: H04N19/625
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To facilitate the format conversion processing and to increase the format converting speed by applying the band limit processing to the discrete cosine coefficient data to decrease the high band components and also applying the interpolation processing to the decoded image data to change coincidence with the number of pixels of a frame image to be decoded. SOLUTION: When the coded data D1 are decoded, the band limit processing is applied to DCT coefficient data D5 outputted from an inverse quantization part 4, via a masking part 21 to decrease the high band components. Meanwhile, the horizontal and vertical interpolation processes are applied to the image data outputted from an addition circuit 6 via an interpolation filter part 23 to convert the image data into an image format. Thus, the band limit processing is performed in a DCT coefficient step to eliminate the need for preparing both horizontal and vertical band limit processing circuits independently of each other. Furthermore, the band limit processing is performed in a DCT coefficient step, where the quantity of data is reduced and before the inverse DCT decoding processing. As a result, the format converting speed is increased.

Title: Optical connector
Inventor: UMEKI KAORU
IPC: G02B6/38
Filed: 1985-09-30
Abstract: PURPOSE:To simplify detaching and attaching work by linking a sliding frame to an adapter as said frame is combined with a plug. CONSTITUTION:A projection 14b in the vicinity of an elastic locking piece 14 is pushed up by projection parts 43a and 44a in the vicinity of the sliding frame. The tip of the elastic rocking piece 14 bends upwardly, and a locking claw 14a can advance over a projection formed before the recessed part 21a of the plug 20. As the insertion depth further increases, the upward bending of the elastic locking piece 14 is released because the projection 14b passes through the positions of the projections 43a and 44a. Then the locking claw 14a passes through the opening part 41 of the sliding frame 40, and drops in the recessed part 21a formed on the front surface of the plug 20. Due to the dropping of the locking claw 14a in the recessed part 21a, the adapter 10 and the plug 20 cannot advance and retreat, thereby completing the mechanical linkage of them.

Abstract: PROBLEM TO BE SOLVED: To improve the response speed in temperature control using a heat exchanger by equipping a controller with a disturbance estimating observer structured by representing the input/output characteristics of the exchanger as a feedback type transfer function and then developing the transfer function. SOLUTION: The quantity of a current supplied to a thermoelectric module 28 is adjusted by using the controller 20 of a robust control system having a disturbance estimating observer 12 built in to control the temperature of a controlled system 16. The temperature of the controlled system 16 is measured by a temperature sensor 18 and fed back to the controller 20. The controller 20 adjusts the quantity of the current supplied to a thermoelectric heat exchanger 27 according to target temperature T0 and the temperature T detected by a temperature sensor 18.  The disturbance estimating observer 12 is structured by representing the input/output characteristics of the thermoelectric heat exchanger 27 as a feedback type transfer function and developing the transfer function, and hence an adequate disturbance estimation value is outputted irrelevantly to the complicated input/output characteristics of the thermoelectric heat exchanger 27.

Abstract: PROBLEM TO BE SOLVED: To concentrate the reflected light to the observer's side and to obtain an easily visible display with a large angle of view by controlling the pitch and height of irregularities randomly formed on a substrate facing the liquid crystal layer to specified values or smaller. SOLUTION: The irregularities are formed on the substrate 3 facing the liquid crystal layer, and a thin metal film is formed as a reflection layer on the rough surface so that the irregularities of the substrate also appear on the metal film surface. The rough surface acts as a light-scattering plane to scatter and reflect the light entering through the observation side. In this method, the irregularities are preferably controlled to give more reflected light to the observer's side, and the rugged pattern is formed with inhomogeneous and random pitches. The average pitch p is preferably controlled to <=80 μm, and more preferably <=10 μm.  The height h of the irregularities are preferably controlled to <=0.6 μm, and more preferably <=0.3 μm considering the alignment stability of the liquid crystal to be held and the concentration of the reflected light to the observer's side.

Title: Lighting control system
Inventor: IGARASHI KAZUYUKI
IPC: H05B37/02
Filed: 1988-09-01
Abstract: PURPOSE:To prevent an excessive increase in traffic between floor controllers by communicating the information of time to each floor controller and converting it into an individual control signal to each individual load control terminal equipment followed by controlling. CONSTITUTION:In the lighting control of lighting equipments 4j, 4k, the information of time from a lighting control system parent equipment 1 is communicated from a memory part 14 to a control part 7. The control part 7 interprets and transmits the communicated command to a communication control part 12a, which sends a control signal to a feed transmission line 4a. A floor controller 2a interprets it as the lighting control request to lighting equipments 4a, 4k, and sends the command to a transmission line 5b after encoding with the load control terminal equipment 3a address. Hence, the transmission of control requests of individual load control terminal equipments to each floor controller 2 is not required, so that the traffic between floor controllers 2 can be reduced.
