Filed: 1981-02-27
Abstract: PURPOSE:To develop short sized photographic films automatically with a required min. amt. of chemical soln. by setting the film to be developed and supplying and discharging the chemical soln. for development of adequate temp. and washing water at constant timings. CONSTITUTION:An opening-closing cover 28 is opened, and a film 1 to be developed is set to a patrone supporting pin 29. The leading end of the film is inserted between rolls 30 and 31, and the cover 28 is closed after which a knob 37 is turned to feed the film into a developing chamber 21. A specified amt. of a developing chemical soln. is fed into a storage tank 41 by opening a plug 43.

Title: Multi-carrier transmission equipment
Inventor: TSUNOISHI MITSUO
IPC: H04J11/00
Filed: 1995-02-17
Abstract: PURPOSE: To reduce the degradation of the transmission quality due to the fluctuation of the phase of a sampling clock by weighting the analog signal, which is generated by D/A conversion, based on a prescribed transmission characteristic thus equalizing and transmitting it. CONSTITUTION: An inverse fast Fourier FFT means 11 regards transmission information, which is divided in the order of time series by a prescribed word length, as levels of frequency slots arranged at equal intervals on the frequency base to perform the inverse east Fourier transformation. A D/A conversion means 13 subjects the bit string generated by the inverse FFT means 11 to D/A conversion in the order of time series to generate an analog signal and supplies it to an equalizing transmission means 15. This means 15 has the transmission characteristic, where the gain is given as a monotone non-decreasing function of frequency, and weights the analog signal, which is generated by the conversion means 13, based on this transmission characteristic and transmits it to a transmission line. Then, the difference in frequency of a subchannel is compressed on the reception end with respect to the bit error due to the rounding error of digital operation or the other noise.

Title: Cassette tape recorder
Inventor: ISHIOKA KIYOSHI
IPC: G11B15/28
Filed: 1984-02-20
Abstract: PURPOSE:To prevent a draw-in phenomenon and the damage of a tape in a tape loading/unloading mode by cutting the 2nd metal and a metallic housing so that they are not protruded toward the tape beyond a capstan tangent line and setting a capstan drop-off preventing ring above the 1st metal. CONSTITUTION:A capstan upper metal part 17 is cut by half at the tapeside so that it remains only at the side the press contact force of a pinch roller 7 is received. At the same time, a metallic housing 19 is also cut by half at the tape side. Thus it is impossible to load and unload a tape along a capstan in the tape cassette loading/unloading mode. This recorder prevents the hitch between the tape and the metal 17 and the housing 19 and therefore avoids a draw-in phenomenon and the damage of the tape. In addition, a capstan drop-off preventing ring 20 is set above a cylindrical lower metal to improve the above-mentioned effects.

Abstract: PURPOSE:To improve the recording density with less space between the nozzles by integrating the electrode plates having adjacent deflection electrodes possite to each other on both sides of the dielectric plate in such a manner that the creeping distance is longer than the straight distance between the two electrodes. CONSTITUTION:A dielectric plate 26 is composed of a plastic film or a thin plate like the acrylic plate. A negative electrode plate 22b and a positive electrode plate 23a are integral mounted on both sides of the dielectric plate being coated with copper, silver or other conductive metal by evaporation or other method in such a manner that the creeping distance is larger than the straight distance between the electrodes, so to speak leaving the periphery of the dielectric plate 26. With such an arrangement, application of high voltage causes no dielectric breakdown despite an extremely small space between the electrodes. Accordingly, the recording density can be improved with a lessened space of the nozzles.
