Title: Method and device for electrolytically treating strip
Inventor: MURAKAMI SHINJIRO
IPC: C25F1/00
Filed: 1987-04-15
Abstract: PURPOSE:To carry out uniform electrolytic treatment of a steel strip by varying the interval between an electrode and the strip traveling along the electrode so that the electric resistance of an electrolytic soln. flowing through the space between them in a direction reverse to the traveling direction of the strip is made uniform. CONSTITUTION:A steel strip 2 is traveled in the direction of an arrow A with two turn rolls 3, 4 and a winding roll 5 rotating in the direction of an arrow. An Ni-Zn alloy plating soln. is fed from an ejection nozzle 7 to the space between the strip 2 and an electrode 6 confronting the strip 2 and the fed soln. is allowed to flow in a direction reverse to the traveling direction of the strip 2 and discharged from a discharge nozzle 8. While the soln. is allowed to flow, electric current is supplied between the electrode 6 as the insoluble anode and the roll 5 as the cathode to form a plated Ni-Zn alloy film on the surface of the strip 2. At this time, gaseous oxygen is generated from the anode 6 and the current density lowers gradually by a change of the specific resistance of the plating soln. to vary the ratio between Ni and Zn deposited. In order to keep the ratio constant, the interval between the strip 2 as the cathode and the anode 6 is narrowed in the direction of 10 11 12. A plated Ni-Zn alloy film having a uniform compsn. can be formed from the beginning of plating to the end.

Title: Method and apparatus for printing onto corrugated sheet
Inventor: HIBINO TAKASHI
IPC: B41F31/02
Filed: 1991-03-29
Abstract: PURPOSE:To apply a printing technique which requires minimized ink consumption, makes possible rapid ink replacement and a subsequent directly connected process at the time of an order change and also enables clear printing onto a corrugated sheet. CONSTITUTION:A low viscosity, rapid-drying ink is supplied to an area between an ink transfer roll 50 which can freely come in contact with and becomes separated from a plate cylinder 44 and a pressing roll 52 which rotates in contact with said roll 50, without being circulated. Then the ink is transferred to a printing plate 42 when the transfer roll 50 is allowed to come close to the plate cylinder 44, and when color is changed, ink sticking to the transfer roll 50 and the pressing roll 52 is removed directly using a scraper 72 or indirectly. A corrugated sheet after printing can be fed directly to a subsequent process so that an operator need not monitor a printing condition constantly. In addition, the overall structure of a printer can be simplified as the ink need not be circulated constantly and the ink consumption is minimized. Further, when color is changed, the ink sticking to the roll has only to be removed by scraping it off so that an order change takes place in a short time and small-lot printing can be most ideally dealt with.

Title: System and device for radio transmission and reception with optical fiber
Inventor: KITAYAMA KENICHI
IPC: H04B10/43
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To reduced the cost of a radio base station(BS) and to simplify its configuration by receiving a downlink sub carrier multiplexed(SCM) signal at the same time with transfer to an uplink from a receiving radio terminal in the BS and inserting and withdrawing an optical signal. SOLUTION: A control station(CS) 7 transmits a downlink SCM optical signal and continuous light for an uplink. In a transmitter of the CS 7, a data signal in an IF band is upconverted into a millimeter wave band by a millimeter wave local signal and subsequently applied to an optical modulator. A continuous light output of a laser beam light source whose wavelength is different is transmitted to a BS 8 by a different millimeter wave signal. In the uplink, the SCM optical signal branched by a wavelength demultiplexer in each wavelength, and subsequently, only an SCM optical signal with a specific wavelength is received and demodulated by a photodetector. Thus, a downlink SCM signal is received at the same time with the transfer to the uplink from a receiving radio terminal in the BC 8, and the optical signal is inserted and pulled down.

Title: Semiconductor laser
Inventor: MITSUNAGA KAZUMASA
IPC: H01S5/34
Filed: 1984-05-08
Abstract: PURPOSE:To improve luminous efficiency, and to lower oscillation value currents by forming an active layer held by clad layers in quantum well type potential structure and flowing electrons and holes in the direction parallel with boundary surfaces among the clad layers and the active layer. CONSTITUTION:When well layers 50 are made shorter than the de Broglie wavelength of carriers in a semiconductor, injecting carrier density required for laser oscillation reduces due to a quantum size effect, and oscillation value currents are minimized largely. When differences among the band gaps of barrier layers 9 and the well layers 50 are formed in large values in order to inject carriers in parallel with boundary surfaces among clad layers 4, 6 and an active layer 5, current injection efficiency is not deteriorated, couplings among the well layers can be reduced sufficiently, a quantum level can be made sufficiently higher than the band gaps of the well layers without increasing oscillation value currents, and laser oscillation at short wavelengths is facilitated. Since quantum well type potential structure is formed, gain spectral width is reduced to one several-th of conventional devices, thus resulting in easy single longitudinal mode oscillation.
