Patent JP-S60140096-A (JP)
Title: Explosion-proof type heat exchange device
Inventor: OONISHI TETSUYA
IPC: B01J7/00
Filed: 1983-12-27
Abstract: PURPOSE:To contrive to prevent a boiler from exploding by a structure wherein a check valve is provided in a water supply pipe on the downstream side of a pump and a safety valve and a shut-off mechanism is provided in a water return pipe running between a vaporizer and a bypass pipe arranged between the water supply pipe and the water return pipe in order to collect the gas leaked in the vaporizer in the shut-off mechanism. CONSTITUTION:When gas leaks in a vaporizer (a) during operation, the leaked gas flows through a water return pipe (e) down into a shut-off mechanism 2, resulting in accumulating the gas in the upper layer of a gas-liquid separation chamber 2c. Consequently, the buoyancy applied on a float 3 is lost and simultaneously the float 3 gradually falls down. Finally a valve plate 4 blocks a valve seat 2d with the further increase of leakage gas. Because the delivered hot water passes through a check valve 7 and flows in the shut-off mechanism even after the shut-off mechanism is blocked, the blockage of the valve seat 2d by the valve plate 4 is strongly kept by the water pressure applied on the back face of the valve plate 4, resulting in enabling to surely store the leakage gas in the gas-liquid separation chamber 2c. On the other hand, the pressure of hot water on the vaporizer side rises abruptly, resulting in opening a relief valve 6 so as to form a circulating passage. Accordingly, the leakage gas in the shut-off mechanism 2 does not flow into a boiler (b) and consequently explosion accident and the like can be surely prevented from occurring.

Title: Inspection of semi-transparent container
Inventor: TEIMOSHII JIEI NITSUKUSU
IPC: G01L5/00
Filed: 1994-09-16
Abstract: PURPOSE: To provide a device and a method which are capable of detecting and checking non-vertical, radial cracks and other cracks in the side wall of a container. CONSTITUTION: This is a device which is capable of detecting cracks in the side wall of a translucent container 22 and in which illuminating light beams project any points on a strip from multi-different angles, and which contains a light source 24 for illuminating a long-narrow strip parallel to the central axis of the container in the container wall. A camera 50 is arranged outside the container to receive a light reflected on the cracks in the illuminated strip, and an electronic circuit 52 is connected to the camera to detect the cracks in the container as a function of the reflected light.  Since the light beams on any points in the illuminated, long narrow strip of the container wall come from mutli-different angles, plane cracks and other cracks in the container side wall which are not exactly vertical with respect to their direction, increase much more the number of the chances where a light energy is reflected form the light source to the camera.

Title: Method for removing nitrogen and suspended matter in wastewater and removal system therefor
Inventor: ENZAKI MASAYUKI
IPC: B01D29/62
Filed: 1998-09-03
Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently removing nitrogen in the secondary treated water of sewage or the like. SOLUTION: This method comprises adding a hydrogen donor such as methanol to feed wastewater, transferring the wastewater contg. the hydrogen donor to a moving bed type upflow filter 1 having a filter medium backwash function and further, recycling and adding a part of backwash wastewater discharged from the filter 1 to the feed wastewater, to biologically decompose nitrogen components in the feed wastewater and to filter and remove suspended solid in the feed wastewater. In the method, since the filtration operation and the filter medium backwash operation can continuously be performed in parallel, the clogging of a filter bed 6 due to the generation of biofilm can be inhibited from being caused and long-term continuous filtration operation can be performed.  Also, since the backwash wastewater which abundantly contains organisms grown in the filter bed 6 and has a low oxidation-reduction potential, is returned to the feed wastewater, nitrogen removal from the feed wastewater proceeds even for the period of time before the feed wastewater reaches the filter bed 6 and further, the amount of organisms in the filter bed 6 is increased to effectively enhance the nitrogen removal rate.

Title: Contact electrostatic charging device
Inventor: INOUE TAKAHIRO
IPC: G03G15/02
Filed: 1991-09-27
Abstract: PURPOSE:To cancel the force of a vibrating electric field which operates between an electrophotographic sensitive body and an electrostatic charging member and to eliminate an electrostatic charging sound and fusion by performing electrostatic charging through a gelled elastic body which has conductivity. CONSTITUTION:The vibrating electric field (AC) on which a DC voltage (DC) is superposed is applied between the electrophotographic sensitive obyd 1 and an electrostatic charging roller 2 and a voltage which is neawrly equal to the DC voltage is converged on the surface of the electrophotographic sensitive body. A spring applies the pressing force to the mandrel 21 of the electrostatic charging roller 2 so as to secure the adhesibility between the surfaces of the electrophotographic sensitive body 1 and electrostatic charging roller 2. The gelled elastic body 22 has viscoelasticity and is soft and low in strength and when the vibrating voltage is applied, it is to be deformed. At the applied frequency, however, the deformation is not enough, so the electrostatic charging roller 2 is hardly vibrated. Consequently, neither the electrostatic charging sound nor fusion caused by the vibration is generated.

Title: Digital etching method
Inventor: MEGURO TAKASHI
IPC: G11B9/14
Filed: 1989-09-26
Abstract: PURPOSE:To make it possible to obtain etching characteristics, which are stable and have a controllability in an atomic layer level, by a method wherein before a beam is projected, reactive gas is evacuated and the reactive gas which does not contribute to adsorption to the surfaces of solid materials is evacuated from the interior of a container. CONSTITUTION:This digital etching method is a method wherein reactive gas 2 is adsorbed to the surfaces of solid materials 1 in a container and after this gas is evacuated, an etching is controlled at an atomic layer level by repeating a process for projecting a charged particle beam or an optical beam 3. That is, by the adsorption of the gas 2 to the surfaces of the materials 1, the coupling of adsorbed solid atoms 1' with the materials 1 is weakened, then, the atoms 1' only weakened their coupling are etched through the materials 1 with the charged particle beam or the optical beam 3 which is projected. Thereby, stable etching characteristics which do not depend on the amount of the gas 2, which is fed, and the amount of the beam, which is projected, can be realized having a controllability at the atomic layer level.

And the separation signal CK, 1/2, 1/4, and 1/8CK signals are sent sequentially to spectrum analysis circuits 24-21 and allocation bit number decision circuits 34-31, respectively. Therefore, the maximum spectrum analysis detection time interval can be obtained at the circuit 21, and the minimum spectrum analysis detection time interval can be obtained at the circuit 24 in order. In such a manner, it is possible to perform efficient spectrum analysis when the audio signal is quantized while matching with the frequency analyzing performance of human hearing by changing the detection time interval of the spectrum analysis.
