Abstract: PROBLEM TO BE SOLVED: To obtain a wavelength-stabilized coherent light source capable of wavelength-stabilized control at high speed by specifying an arbitrary wave length. SOLUTION: Part of output light of a semiconductor laser 1 capable of variably controlling the wavelength with current is split with a beam splitter 3 and introduced to a interference optical system 5.

Filed: 1995-07-13
Abstract: PROBLEM TO BE SOLVED: To use a coaxial dielectric resonator which can sufficiently sustain even an excessive stress by mounting coaxial dielectric resonators on a circuit board in such positions that they are not brought into contact with each other. SOLUTION: The length of one side and that of the other of a coaxial dielectric resonator 1 are denoted as (a) and (b), and the interval of mounted resonators is denoted as (c). This interval is different by shapes or the like of coaxial dielectric resonators 1, but experimentally, it is sufficient if the interval is about 5 to 10% of the length (a) of one side of the coaxial dielectric resonator 1. With respect to joining, solder paste is coated on a circuit board 2 with a prescribed pattern, and coaxial dielectric resonators 1 are so mounted that they are not brought into contact with each other, and they are heated at a prescribed temperature in a reflow furnace, thus joining them.  Since coaxial dielectric resonators are mounted in such positions that they are not brought into contact with each other, the stress is distributed, and the joining strength is secured and the partially applied stress is reduced.

Title: Leftover detection of rolled recording paper
Inventor: YOKOCHI TOSHIYUKI
IPC: B65H23/00
Filed: 1984-09-28
Abstract: PURPOSE:To make detection of leftover low-priced high precision roll paper quantity possible by detecting a leftover quantity of recording paper on the basis of detection results of identification information. CONSTITUTION:A control block 15 makes a logic sum signal of an output signal of a reflective photosensor 14 and a drive pulse signal to be supplied to a drive block 16 for rotating a platen roller 13, and measures a length of pattern by calculating the number of continuous pulses in this logic sum signal. The control block 15 reads from a memory 17 leftover length indication data corresponding to the counted number of pulses and sends it to a display block 18. The display block 18 indicates a leftover length of recording paper based on inputted leftover length of recording paper based on inputted leftover indication data, but the content of indication is not updated until a next pattern is detected. Thus it is made possible to accurately detect a leftover length of rolled recording paper under a simple configuration without depending upon a complicated mechanical structure.

Filed: 1987-08-14
Abstract: PURPOSE:To attain a coupling operation when a coupler is not observed from a driver seat by projecting a video signal, which is image-picked up by an ITV camera, to a monitoring television on a vehicle. CONSTITUTION:A ground equipment sends the video signal of an ITV camera 4, which is provided on a position where the coupling condition of a train can be visually confirmed, to the train at an emitting angle theta by an emitter 5 for optical spatial communication. A loaded equipment on vehicle receives the optical signal of the emitter 5 by a light receiving device 6 and the signal light- received there is projected to a monitoring television 7. Accordingly, when a driver drives a train while proceeding the train at a low speed, a train 3 goes into the view of the ITV camera 4 soon and both trains 2 and 3 are projected to the monitoring television 7. Thus, a distance interval between both trains can be read from the monitoring television 7 and the driver can execute the coupling work 8 while supervizing the monitoring television 7.

Filed: 1984-09-28
Abstract: PURPOSE:To reproduce a stable reference signal phase-locked with an arrival reference signal without being influenced by a noise even at the time of a weak electric field, by detecting a phase state and reproducing digitally the reference signal. CONSTITUTION:A reference clock CK for sampling a character broadcasting signal is applied to a terminal 1. This clock CK is counted by a counter 11, and based on this counting value, a decoder 12 outputs various timing signals P1-P7. Based on this timing signal, a flip-flop 13 reproduces a horizontal synchronizing signal and outputs it to a terminal 2. Also, a receiving horizontal synchronizing signal which has been brought to synchronizing separation is applied to a terminal 3, and in accordance with this signal and a reproducing reference signal from the decoder 12, three kinds of phase states are outputted from a phase detecting part 43. This detecting output is integrated by an integrating part 61, and a noise component is eliminated. By this detecting output, a phase correcting part 51 sets a frequency dividing ratio of the counter 11, and phases of various timing signals are corrected.

Abstract: PURPOSE:To enable continuous supply of sheets to be achieved by simple operation, duly accompanied by enhanced efficiency of work, by processing the sheet feed work in such a way as placing sheets on a plurality of mutually facing pallets fixed to the chains or the like laid round a sprocket or the like. CONSTITUTION:The bottom door of a framework is opened and sheets 8 are placed on pallets 6a, 6b on the bottom. Thereafter, sprockets 3a, 3b are rotated to lift the pallets 6a, 6b by one step while the same process is repeated to the next step, thus sheets 8 are load on respective pallets 6a, 6b on 4 steps. Then, when sheets 8 are adsorbed to a transport device and the height of the sheets 8 is decreased, a motor turns to lift the next pallets 6a, 6b and when the upper face of the sheets 8 reaches a limit switch, the motor ceases its turn. When all the sheets on the pallets 6a, 6b are conveyed to a bucket, the pallets 6a, 6b on the next step are lifted to top position and the bucket moves away and an empty bucket receives the sheets 8 and sends them to a folding device. Continuous supply of sheet can be achieved by repeating this process.
