Filed: 1980-10-27
Abstract: PURPOSE: To enable lighting of a plurality of lamps in a lighting confirming device to be confirmed positively by connecting an amplifying switching element to a light receiving element for detecting optical spectrum to light an indicator by color.  
     CONSTITUTION: When a lamp L 1  to be detected is lit, only optical spectrum with blue color wave length from an optical blue filber 2a is optically introduced into a photoconductive fiber 3a, and other optical spectra of lamps L 2 , L 3  are optically introduced into a relay fiber to be composed with said optical spectrum. This radiation is divided by a triangular prism section so that, when said optical spectrum with blue color wave length is incident upon a phototransistor Tr 1 , current corresponding to intensity of the light flows through the phototransistor Tr 1 . At this time the base level of a switching transistor Tr 3  is lowered not to light a luminescent diode D 2  so that a indicating window (red colored) of an indicator does not indicate the luminescence. On the other hand, the base level of the switching transistor Tr 2  is raised to light a luminescent diode D 1  so that the indicating window (green colored) of the indicator indicates the luminescence.

Abstract: PURPOSE:To reduce a total work time for withdrawing required pallets simultaneously from a plurality of lanes by checking the residual number of delivery pallets in each lane, and delivering them from the lanes having more residual numbers with priority for evening the residual numbers of pallets in the lanes. CONSTITUTION:When a delivery instruction for required pallets is outputted from an automatic storage reception/delivery instruction device 10, a computation and indexing device 9 determines the number of pallets to be delivered from each lane based on inventory management data, and gives an instruction to a control device 8 based on the number of pallets to be delivered for each lane. The control device 8 transfers the pallets up to a maximum storage number possible for all the work conveyors for no conditions. For a number more than the maximum storage pallet number possible, the residual number of delivery pallets are checked constantly for each lane, and the delivery pallets are withdrawn and transferred from the lanes having more residual numbers with priority for evening the residual number for the lanes. In this constitution, total work time can be reduced.

Title: Electromagnetic driving device
Inventor: MITSUMOTO TAKASHI
IPC: H01F7/16
Filed: 1980-10-24
Abstract: PURPOSE:To prevent the leak of magnetic flux and to obtain a large stroke by arranging electromagnets coaxially on the lateral side of an iron core at a prescribed interval, by connecting a rod connected with a driven body to the electromagnet positioned remotes from the iron core and by attracting the electromagnets sequentially from the remotest one. CONSTITUTION:When voltage is applied to a solenoid 24, an attracting force is generated between the electromagnets 16 and 15. However, since the electormagnet 15 is incapable of moving to the right because of the presence of a connecting wire 27, the magnet 16 moves to the left against a spring 32 and is attracted to the magnet 15. When the magnet 15 is excited while the magnet 16 is being excited, the attracting force is generated between the magnet 15 and the magnet 10, but since the magnet 10 is incapable of moving to the right by the presence of a connecting wire 26, the magnet 16 moves to the left and is attracted to the magnet 10, and finally the magnets 16, 15 and 10 are attracted integrally to the iron core 25 in the same way. Although the stroke of each magnet is small in this constitution, the leak of magnetic flux is prevented and the rod 29 fitted to the magnet 16 operates the driven body at a large stroke and by a large force as a whole.

Title: Deflection device for raster scanning crt display device and computer system
Inventor: ANDORUU JIYON MOORITSUSHIYU
IPC: H04N3/22
Filed: 1993-06-22
Abstract: PURPOSE: To provide a deflector with which a raster scan cathode-ray tube(CRT) device can maintain a fixed picture size, even when a raster line scanning frequency is changed. CONSTITUTION: The deflector for a raster-scan CRT display device is provided with a ramp generator 210 for generating a ramp current signal which synchronized with a raster synchronizing signal. A ramp regulator 230 changes the amplitude of scanning signal as a function of difference between a reference input and a feedback signal, while being connected to this generator 210. A feedback circuit 220 is connected to the generator 210 and the adjuster 230 and generates the feedback signal as the function of amplitude and frequency of line scanning signal. A multiplier 250 is connected to this regulator and changes the reference input as an integral multiple function of the frequency of raster synchronizing signal.  A scanning signal frequency component in this feedback signal is canceled at the input of regulator by leading that scanning signal frequency component through the multiplier 250 into the reference input.
