Title: Sound volume adjusting device in digital audio system
Inventor: SATO MASATO
IPC: H03G1/04
Filed: 1987-05-30
Abstract: PURPOSE:To obtain a sound volume adjusting device with a wide adjusting range and less distortion by providing 1st and 2nd analog sound volume adjusting means and a control section selecting the combination of sound volume adjusting means in response to the indicated sound volume adjusting level. CONSTITUTION:With switches 11, 12 of the 1st analog sound volume adjusting means 13 opened, a feedback element of a current/voltage converter (IVC) 3 is only a resistor R10 to bring the attenuation to 0dB. With the switch 11 closed, the attenuation is 6dB and when both the switches are closed, the attenua tion is 12dB. On the other hand, the 2nd analog sound volume adjusting means 14 offers an attenuation of 0dB with the switches 21, 22 opened and gives an attenuation of 12dB with the switch 21 closed. When both the switches are closed, the attenuation is set to be 24dB. The switches 11, 12 and 21, 22 are switched by a command from a CPU 9 to apply analog sound volume adjustment through a prescribed combination in a prescribed dB step.

Abstract: PURPOSE:To facilitate the removal operation of the head of a pile without generating dust and noise by a method in which a reinforcing bar shield device is brought down, the upper part of reinforcing bars is inserted into the space between inner and outer cylinders, and concrete is placed in such a way as to avoid the adherence of concrete to the upper part of the reinforcing bars. CONSTITUTION:A reinforcing bar shield device 1 is brought down, the upper part of reinforcing bars 18 is inserted between inner and outer cylinders 3 and 4, and a concrete-pouring tube 14 is inserted into the center of the device 1. Concrete is placed into a formwork 17 through the tube 14. Since no air is present the space between the inner and outer cylinders 3 and 4, concrete does not come in from below and concrete does not adhere to the upper part of the reinforcing bars 18. Before the concrete hardens, the formwork 17 is pulled off, and after the concrete hardens, the device 1 is lifted up. By breaking a constricted portion E formed by the guide 13 of the device 1, the head D of the concrete pile is removed out.

Title: Treatment of sulfur-containing fuel
Inventor: AKIMOTO SHINKICHI
IPC: C10L10/00
Filed: 1980-10-01
Abstract: PURPOSE: To remove sulfur compds. as an alkaline earth metal surface and to make the simple and inexpensive treatment of fuel possible without emission of SO 2 , by mixing an alkaline earth metal oxide or hydroxide with sulfur-contg. fuel, and injecting and burning the mixture.  
     CONSTITUTION: An equivalent amount (based on the amount of sulfur in fuel) or a slightly excess amount of an alkalin earth metal oxide or hydroxide is mixed with fuel contg. sulfur or sulfur compds. and injected directly from a combustion burner for combustion. When the fuel is heated to 530W580°C in the reducing the flame zone of a stabilization zone, H 2 S evolved in said zone is set as an alkalin earth matal sulfide which is then oxidized in an oxidizing flame atmosphere at 1,000°C or higher to produce a combustion residue, thus suppressing SO 2  generation. This combustion residue and a proper residue from the fuel are collected and removed in a melt- kneaded state by a dust collector.

Title: Excitation device of lifting electric magnet
Inventor: IWAKI KOICHI
IPC: H02M7/19
Filed: 1989-05-31
Abstract: PURPOSE:To eliminate the need for a power supply transformer with large capacity and to provide an excitation device of lifting electric magnet which achieves required initial excitation only by adding a simple circuit of short-time rating by constituting a booster circuit generating an output voltage which is added to the output voltage of a main excitation circuit for initial excitation using a switching element and a diode including a transformer with a small capacity. CONSTITUTION:Switching elements 31a and 31b of a booster circuit 3 conduct current by a controller 4 for initial excitation of a lifting electric magnet 1. Through a transformer 32, for example, the boosted alternate current generates a specified DC voltage using a parallel circuit of the switching elements 31a and 31b and diodes 30a and 30b. On the other hand, even in a main excitation circuit 2, the power rectifying circuit generates a specified excitation voltage. However, since the output side of the main excitation circuit 2 is connected to the output side of the booster circuit 3 in series, output voltage of the booster circuit 3 is added to the output voltage of a main excitation circuit 2, thus producing an overshoot voltage of a specified initial excitation voltage, which is applied to the coil of an electromagnet 1, thus increasing the leading edge of current flowing to the coil.

Title: Communication pulse light source device
Inventor: TAKADA ATSUSHI
IPC: H01S5/0687
Filed: 1993-06-07
Abstract: PURPOSE:To reduce a frequency fluctuation between pulses and suppress pulse expansion after an optical fiber transmission and an increase in timing jitters by a method wherein a fluctuation of optical frequency between beam pulses is detected and a feedback loop into a change part of a refractive index is arranged so as to minimize the fluctuation portion. CONSTITUTION:An optical interferometer 7 acts as an optical frequency-strength converter that a change portion of the optical frequency is converted into a change of strength of output beams as to a certain longitudinal mode of an inputted light wave. The thus-generated outputs of the optical interferometer 7 are converted into electric signals by an optical converter 8 and sent to an electric circuit part 9. The electric circuit part 9 transmits signals to a refractive index change part 3 so that input electric signals can be constant, namely frequency of beam pulses can be constant. An increase in line width, namely a fluctuation of the optical frequency between pulses can be suppressed by modulating an effective resonator length by changing the refractive index within the optical reso-l nator 4.
