Title: Manufacturing instrument for optical transmission module
Inventor: SHIGA NOBUO
IPC: G02B6/42
Filed: 1988-08-31
Abstract: PURPOSE:To accurately fix an optical fiber at the best position by obtaining a light output by measuring the temperature of a semiconductor laser and also measuring a light output in advance, correcting the light output and the shifting of the optical axis according to the relation between the obtained light output and temperature, and soldering the optical fiber at the position where the coupling efficiency is maximum. CONSTITUTION:The module 1 is heated by a heating device 7 and variation of the light output with the temperature of the semiconductor laser is measured by an optical power meter 5 through an optical fiber 2 and stored in a microcomputer 13. Then while the temperature of the semiconductor laser is measured, the light output after passing through the optical fiber 2 is measured by the optical power meter 5 and the optical fiber 2 is soldered to the module 1 at the position where the coupling efficiency becomes maximum. At such a time, the light output of the semiconductor laser heated during the soldering is found and compared with the light output measured by the optical power meter 5 to control manipulators 10 and 11 so that the optical fiber 2 is soldered at the position where the coupling efficiency becomes maximum. Consequently, the optical fiber 2 is soldered at the position where the coupling efficiency becomes maximum.

Title: Tool path producing device
Inventor: MAEDA YASUYUKI
IPC: G05B19/4093
Filed: 1987-08-31
Abstract: PURPOSE:To effectively produce a tool path even with a product to be worked that has a complicated contour by dividing the shape of said product stored in a memory part into a partial path to be deleted and the other remaining part and producing repetitively the partial paths to said remaining part for connection of the adjacent partial paths. CONSTITUTION:A working shape memory part 1 stores the contour data of a product to be worked and a degeneration arithmetic part 2 reduces the shape of the product toward the inside from the outer circumference by an effective cutting width decided by the size of a tool. Then the part 2 stores a new working shape into the part 1. A partial path producing part 3 produces a graphic shape to be deleted from the product to be worked as a partial path and stores this path in a partial path memory part 4. These degeneration arithmetic and partial path production processes are repeated so that the outer shape of the product is decomposed into plural partial paths and stored in the part 4. These partial paths are connected together by a continuous path producing part 5 for production of a tool path. This obtained tool path is stored in a tool path memory part 6.

Abstract: PURPOSE:To collect the stall factor information even in the case of a power supply trouble of a central processing unit CPU, by adding an exclusive power supply device to a stall monitor device and at the same time setting the monitor time via a service processor. CONSTITUTION:The power supply devices different from those of CPU11 and 12 are added to stall monitor devices 21 and 22. Then the monitor time can be set to both devices 21 and 22 via an external service processor 6. Thus both devices 21 and 22 replace the set values at fixed time intervals and informs the end of replacement to the processor 6 when said end of replacement is detected. Thus the processor 6 knows that the CPU11 and 12 are stalled and gives this information to an operating system. At the same time, the processor 6 sets again the monitor time at both devices 21 and 22 and stops the entire working of the system with the second information at the end of replacement received from the devices 21 and 22 to collect the information to study the stall factors.

IPC: H04W16/32
Filed: 1993-09-03
Abstract: PURPOSE:To form the radio communication system capable of the extension of a service area and hand-over between radio base stations in accordance with the movement of a portable radio terminal. CONSTITUTION:This system is composed of plural outgoing radio base stations 101 to respectively form macro-cells, plural incoming radio base stations 102 to form microcells inside the respective macro-cells, and a mobile communication control station 100 connected between each outgoing radio base station and a public or private network 109. By monitoring the level of a received signal from the portable radio terminal at each incoming radio base station, this mobile communication control station 100 performs the specification of the incoming radio base station to manage each portable radio terminal and hand over control. Therefore, since the incoming radio base station is arranged for each microcell, the transmission power of each portable radio terminal can be made weak and since the number of outgoing radio base stations and mobile communication control stations to be installed is increased, the service area can easily be enlarged.

Title: Detection of inner surface defect of cylindrical work
Inventor: FUNAHASHI MITSURU
IPC: G06T7/00
Filed: 1989-08-25
Abstract: PURPOSE:To make it possible to ensure the detection of defects at the inner surface of a cylindrical work in a short time by comparing the luminance of each picture element with two threshold values which are set in response to the illumination irregularities. CONSTITUTION:Lighting is applied on the inner surface of a cylindrical work at a low angle. The image of the inner surface is picked up with a two-dimensional camera, and the image is outputted to an image processing device. Since the object to be photographed has the curved surface, illumination irregularities are formed in the obtained image. The luminance value itself at a place without irregularities becomes the curved state. With a curved base line C as a reference, the luminance value at a protruding part 1 on a position line B is increased. The luminance value at a recess part 2 is decreased. Then, the luminance of each picture element is compared with preset two threshold values D and E. A picture element F whose luminance value is larger than one threshold level D having the smaller value is obtained. A picture element E whose luminance value is smaller than smaller threshold value is obtained. The picture elements F and E and the other picture element are binary-coded. The picture element F whose luminance value is larger than one threshold value D whose value is large and the picture element G whose luminance value is smaller than the other smaller threshold value E are detected as the inner defects of the work.
