Title: Light-emitting diode lamp with dioptric lens element
Inventor: KEBUIN GURANTO OORUSUTON
IPC: H01L33/00
Filed: 1992-07-16
Abstract: PURPOSE: To make it possible to illuminate a specific range with minimum power by constituting a lens element so as to obtain a necessary output beam. CONSTITUTION: Each radiation face 110A or 110D passes a beam having each beam center 120A or 120D. Since the radiation face is convex, a parallel beam passing a lens element 106 is converted upon each beam center and allowed to mutually intersect with each other on a plane 125. Then the beam center is generally entered into a convergent band 126 and propagated to an observer 127. When a radius to be applied to a curved surface to the radiation face 110 e.g. is reduced, the beam is intersected at the plane 125 brought more close to the lens element 106, diverged at a large angle and turned to a more widely radiated beam. When the radius of the curved surface of the radiation face 110 is increased, light is converged on a position separated from the lens element 106 correspondingly to the increment of the radius, slowly diverged and turned to a more narrowly converged beam.

Title: Centrifugal compressor
Inventor: FURUYA YASUSHI
IPC: F04D29/44
Filed: 1984-09-12
Abstract: PURPOSE:To enhance the efficiency of a centrifugal compressor, by using return vanes to define a return channel, and by connecting the return channel to the outlet port of a U-turn passage provided at the outlet port of a diffuser, and by providing a vertical collector at the outlet port of the return channel. CONSTITUTION:A fluid having flowed out of a diffuser 2 has its direction shifted from radially outwards to radially inwards by 180 deg., by a U-turn channel 5, and is then guided to a return channel 6 defined by return vanes 13, so that the fluid is released into a collector 3. For that reason, the remaining velocity energy of the fluid at the outlet port of the diffuser 2 is efficiently changed into pressure energy so that the sufficiently decelerated fluid is introduced into the collector 3. The efficiency of a centrifugal compressor is thus enhanced.

Title: Picture coder
Inventor: SAKAGAMI SHIGEO
IPC: H04N19/50
Filed: 1989-07-21
Abstract: PURPOSE:To attain coding without new study as to other picture by inputting a signal having statistic property in common to a picture signal to adders of multi-input one-output connected in hierarchy, giving the signal to an output layer as a teacher signal so as to allow the output layer to be studied. CONSTITUTION:A discrete cosine conversion of an input picture signal Xm is given as a teacher signal. When the study for an output signal in a way of changing its weight is finished, the output signal from an output layer 4 is nearly equal to the result of applying discrete cosine conversion to an input picture signal. When the number of units of an intermediate layer 3 is decreased more than the unit number of the input layer 2 and the output layer 4, an input signal x1 is subjected to high efficient coding by an output signal y1 of the intermediate layer 3 and decoded by the output layer 4. A discrete inverse cosine conversion section 5 applies discrete inverse cosine conversion to an output signal zk of the output layer 4 to obtain an output signal z1 equal to the input picture signal x1. Thus, the picture coder acts like a picture coder effective also to other input picture when a specific input picture is once studied.

Title: Ecr system
Inventor: TERATANI SHIGEKI
IPC: G07G1/14
Filed: 1987-07-29
Abstract: PURPOSE:To prevent infeasibility of communication between remaining ECRs due to the fault of a specific ECR set as a master station from being generated, by operating each ECR as the master station, and operating the ECRs as the master station at a prescribed order. CONSTITUTION:At the time of assuming that the minimum time is set at a first timer circuit 7 in the ECRR1, the first timer circuit 7 in the ECRR1 outputs a first time out signal. Thereby, the ECRR1 detects the time out signal, and is operated as the master station, and sends certain data to a transmission path L. Then, the remaining ECRs R2-Rn receive the data, respectively, and reset the first timer circuits 7. Also, when the ECRR1 is not operated as the master station due to an unknown reason and no data is sent to the transmission path L, the ECR in which the next minimum time is set in its first timer circuit 7 is operated as the master station. Thus, either ECRs R3-Rn functions as the master station, thereby, it is possible to prevent the communication of the whole system from being infeasible.
