Title: Output buffer circuit
Inventor: USUI TOSHIMASA
IPC: H03K17/687
Filed: 1991-09-09
Abstract: PURPOSE:To change the output drive capability matching the operating condition by connecting plural transistors(TRs) of an output final stage in parallel and using a control signal so as to turn off part of the TRs of the output final stage. CONSTITUTION:When an H level is inputted to a control signal input terminal 3, an output of a NOR gate 40 goes to an L level and an output of a NAND gate 35 goes to an H level and TRs 10, 20 are turned off. On the other hand, since an inverse signal at an input terminal 1 is inputted to output TRs 11, 21 through an inverter 31, the TRs are always operated independently of the state of the input terminal 3. Conversely, when an L level is inputted to the input terminal 3, since an inverse signal at the terminal 11 is inputted to the TRs 10, 20, the TRs 10, 11 are simultaneously in operation and the TRs 20, 21 are simultaneously in operation. Thus, a larger output drive capability is obtained in comparison with that when an H level is inputted to the terminal 3.

Title: Production of glass pipe
Inventor: AOKI MIKIO
IPC: C03B8/02
Filed: 1985-10-15
Abstract: PURPOSE:To produce a high-quality glass pipe free from a warpage with excellent mass-productivity by standing vertically tubular gel in the center of a drying vessel having a taper-shaped supporting rod for gel and drying it. CONSTITUTION:In a producing method of a glass pipe due to a sol-gel process wherein alkylsilicate and a fine powder of silica are used as an essential raw material, tubular gel 4 is vertically (+ or -5 deg.) stood in the center of a drying vessel having a taper-shaped supporting rod 1 of gel and dried. Gel is shrunk according to drying but the slant of gel is vanished and therefore gel does not receive the effect due to gravity and a warpage is vanished. Since the shrinkage direction of gel is completely coincident with the direction of gravity, gel is smoothly shrunk and the yield is increased. Therefore a high-purity and high-precision glass pipe can easily be produced with excellent mass-productivity. For example, it can extensively be applied as a furnace core pipe of a diffusion furnace for a semiconductor and a jacket tube for an optical fiber.

Abstract: PURPOSE:To efficiently regenerate exhaust particulate callecting filters at the time of sequential regeneration thereof, by suppressing difference between flow rates of exhaust to be flowed into filters during regeneration which may be caused by order of regeneration, and suppressing unbalanceness between regeneration degrees. CONSTITUTION:A first open/close valve 30 is closed so as to regenerate filters 11, 12 in a first vessel 10 first. The first open/close valve 30 is abutted against a stopper 31 for regulating to a specified value a flow rate of exhaust to be flowed into the first vessel 10. After regenerating the filters 11, 12 orderly, the first valve 30 is opened and a second open/close valve 40 is closed so as to filters 21, 22 in a second vessel 20. The second open/close valve 40 is abutted against a stopper 41 for regulating an amount of exhaust to be flowed into the second vessel 20. An opening of the second valve 40 is set larger than that of the first open/close valve 30 so as to obtain a flow rate of exhaust equal to that at the time of regeneration on the side of the first vessel 10, considering recovery rate of air resistance in the first vessel 10. It is thus possible to suppress difference between amounts of exhaust to be flowed into the filters at the regeneration time, and suppress unbalanceness between regeneration degrees.

Filed: 1990-08-30
Abstract: PURPOSE: To prevent radioactive contamination upon occurrence of a critical accident by stacking a plurality of underground cavities on a basement where a reactor is installed and mounting a mixture of sand, boron powder, etc., contained in each cavity on a fragile floor. CONSTITUTION: An underground facility has a reactor room 13 in which a reactor 14 is installed. A plurality of cavities 12 are provided on the reactor room 13 and the cavity 12 has an unreinforced concrete floor 18. About half of each cavity 12 is filled with an inactive microparticle mixture 28 of sand and boron powder. An explosive 16 is embedded into the mixture 28, for example, in each cavity 12 provided with an access door 119 disposed contiguously to a shaft and running vertically between the bottom and the top of the cavity 12. Since no reinforcing rod is employed in the floor 18 of the cavity 12, the floor 18 is crushed relatively easily by a force of explosion in the reactor room 13. Consequently, the mixture 28 of sand and boron powder falls gravitationally into the reactor room 13 and the reactor 14 is thereby embedded.

Title: Ad converter,da converter,and digital audio processor
Inventor: TAKASHI MATSUSHIGE
IPC: H03M3/02
Filed: 1995-09-07
Abstract: PROBLEM TO BE SOLVED: To reduce the subjective distribution effect of long conversation delay in a return signal path. SOLUTION: These AD converter 10 and DA converter execute a requested conversation at a higher sampling rate (64Fs, for instance) and a lower resolution (1-4 bits, for instance) than requested actual sampling speed (Fs) and resolution (16 bits, for instance). Oversampled low resolution signals are generated by oversampling input digital signals (for DA conversion) and decimated and requested output digital signals (for AD conversion) are generated. The oversampling or decimation filter 20 can be switched between two mode operations and different signal delay is applied by the filter. Thus, in a signal path for the return signals of an artist, the filter of short delay though low quality is used.
