Title: Muting circuit
Inventor: IMAZAWA KOUJI
IPC: H04B1/10
Filed: 1983-10-07
Abstract: PURPOSE:To obtain a muting circuit which forms soft muting of a digital audio signal by forming a simple circuit with a shift register, an interpolation circuit and a latch circuit. CONSTITUTION:The shift register SR receives a digital signal in 16-bit through the interpolation circuit IN. Then the digital signal is shifted by a clock formed by a shift clock generating circuit phi-G. The digital signal shifted by the shift register SR is fetched to a latch circuit L and fed to a digital/analog converter DAC (not shown in a figure). Said shift register SR receives the 16-bit digital audio signal subjected to interpolation one after another in synchronizing with the interpolation of the interpolation circuit IN and applies shift operation of prescribed bit to the signal while the next digital audio signal is received.

Title: Corrosion preventing method for water surface measuring apparatus or water level regulating apparatus for boiler
Inventor: AGATA KUNIO
IPC: F22B37/78
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To reduce local decrease of chemical concentration and to alleviate corrosion in a water surface measuring apparatus by heat insulating the apparatus and a peripheral tube of the apparatus with heat insulators, thereby preventing condensation of steam flowing from a steam side tube of a boiler to the apparatus. SOLUTION: A position of a water level 40 in a boiler 1 can be confirmed by a water gage 26 communicating at upper and lower parts with a water column tube 25 connected at upper and lower parts by a steam side tube 2 and a water side tube 3. Steam flowing from the tube 2 of the boiler 1 to a water surface measuring apparatus 4 is less lowered at its temperature since circumstances of the tube 25, tube 2, tube 3, switching valves 5, 6, drain tube 7, ON/OFF valve 8 for blowoff and the gage 26 are heat insulated by heat insulators 30. Accordingly, condensation of steam is prevented, local dilution of chemical concentration for forming a corrosion preventive film on an iron surface is reduced, and corrosions of the apparatus 4, tube 3 and tube 7 are moderated.

Abstract: PURPOSE:To efficiently carry out an efficiency measuring operation by obtaining volumetric efficiency at a stabilized time based on the maximum volumetric efficiency which can be obtained in a relatively short time, from previously obtained relation between the maximum volumetric efficiency obtained after starting the operation of a pump and volumetric efficiency at the stabilized time of operation. CONSTITUTION:First, input signals from a flow rate sensor, etc. is read, and the then volumetric efficiency (compressibility) etav is obtained from a defined equation for calculation based on these input signals. Then, it is judged whether the volumetric efficiency etav is the maximum value etav max or not. Since the judgment is affirmed about 5 minutes after starting the operation of a Roots vacuum pump 10, volumetric efficiency etava at a stabilized time is calculated based on the maximum volumetric efficiency etav max obtained immediately after starting operation, from previously obtained relation. And, a signal SK for indicating the volumetric efficiency etava is outputted. Accordingly, the volumetric efficiency etava at the stable time of the Roots vacuum pump 10 is displayed on a display, carrying out an efficiency measuring operation efficiently.

Filed: 1991-07-29
Abstract: PURPOSE:To provide a document feed device having the capability of reducing a non-feed rate by restarting (retrying) separation and carriage operation, upon occurrence of non-feed. CONSTITUTION:An S2 sensor 32 makes judgement, regarding the existence or non-existence of a document, and detects the non-feed of the document by detecting the leading end of the document carried with a feed roller as a carriage means. A retry control section 53 causes a separation means and a carriage means to start again separation and carriage operation, when the non-feed of the document is detected by the S2 sensor 32. If the non-feed of the document is detected after the restart of said means, retry state continues. Also, retry by the means is repeated, upon detection of the non-feed. A maximum value for retry repetition, however, is predetermined at the frequency of (n).

Filed: 1986-08-13
Abstract: PURPOSE:To prevent internal short circuit at the end by removing positive active material from the winding end of a positive plate to expose a metal supporter, and fixing a metal plate to the exposed part of the metal supporter. CONSTITUTION:A part of positive active material 1 is removed to expose a metal supporter 2, and a metal plate 3 is fixed to the supporter by spot-welding. Since the burr of the metal supporter and warp at the end of the metal supporter have a harmful effect on the outside, the metal plate 3 is fixed to surface, which is faced to the outside in winding, of the positive plate. The metal plate is extruded from the end of the metal supporter so as to cover its end. A folded metal plate may be used as the metal plate 3, and the inside of the folded part is butted to the winding end of the positive plate so as to cover the end and make positioning easy. Since the both sides of the metal plate, on which welding terminals are placed, are flat, spot welding job is made easy. Problems generating internal short circuit are reduced.
