Title: Abnormality detecting circuit for thyristor converter
Inventor: KOUNO KIMIO
IPC: H02H7/125
Filed: 1978-12-13
Abstract: PURPOSE: To detect an abnormal current when an antiparallel short circuit takes place, by combining an overcurrent detecting circuit with an antiparallel short circuit detecting circuit which utilizes a suppression signals for a forward and a backward silicon controlled rectifier converters.  
     CONSTITUTION: An abnormal current detecting circuit 20 comprises an operational resistor, an operational amplifier, a comparator and an OR circuit. The operational amplifier 20-3 inverts the polarity of a current detection signal of a backward silicon controlled rectifier converter 7. As a result, the polarity of an input signal to another operational amplifier 20-7 becomes negative and the simultaneous currents of direct current transformers 6, 7 due to an antiparallel short circuit do not cancel each other. The comparator 20-14 compares the current with an overcurrent detection level to detect an overcurrent. Thus, the abnormal current under the antiparallel short circuit is detected and a trouble is prevented from expanding.

Title: Signal generating method
Inventor: INOUE HIDEO
IPC: H04N7/01
Filed: 1986-06-30
Abstract: PURPOSE:To freely select a generated signal source without selecting the signal system of an objective device by processing generated signals by an operation. CONSTITUTION:Analog signals inputted from an input end 1 are converted to digital signals by an A/D converter circuit 2 and written in a memory 3. The memory 3 is connected to an arithmetic unit 4, and the content of the memory 3 can be converted to optional form. Since the arithmetic unit 4 is connected to an external storage unit 5, the preservation of the content of the memory 3 and the writing from inside in the memory 3 are possible. Further, optional signal data can be written in the memory 3 by generating optional data by the arithmetic unit 4. Thus, since it becomes possible to change the form of generated signals optionally, the generation of signals of very high degree of freedom becomes possible.

IPC: F16J15/26
Filed: 1978-12-12
Abstract: PURPOSE: To extend the life of the packing and to obtain excellent sealing characteristics by press-welding a multi number of packing pieces with fine clearances with each other in the peripheral direction on the rotary shaft by the packing gland and the garter spring.  
     CONSTITUTION: The sealing surfaces 11c of the packing pieces 11 1 W11 n  arranged in circle around the main shaft 1 is pressure-welded on the outer surface of the main shaft 1 through the packing gland 6 by the spring force of the garter spring 7. Initially, the packing pieces 11 1 W11 n  keep the fine clearances g in the peripheral direction, but the clearances g gradually become smaller as the sealing surface 11c is worn away, until there are no clearances g. From then on, the packing pieces 11 1 W11 n  do not shift. As the packing pieces 11 1 W11 n  are thus constituted so that the fine clearances are gradually decreased, the life of the packing can be extended and the sealing characteristics can be maintained for a long time.

Title: Circuit for generating substrate bias
Inventor: IKEDA SANENARI
IPC: G11C11/407
Filed: 1991-06-26
Abstract: PURPOSE:To freely set an optimum substrate bias at the time of a characteristic test by providing plural oscillating circuits with a different frequency, a switching circuit for changing-over them and a judging circuit judging an operation mode so as to output a switch changing-over signal. CONSTITUTION:An output phi is adopted as an H level and switch elements S and S are respectively turned on and off so that the oscillating circuit 2 is selected and a pulse is supplied to a node (A) in a reading and writing cycle under detecting and testing the test mode of a semiconductor storing device in an operation mode judging equipment 3. Therefore, the potential of the substrate bias VS is set by the frequency of the circuit 2. The lower the potential of the bias VS is, the lower the threshold of a memory element is set and the judgement of normal/defective in the memory element comes to be easy. When the frequency of the circuit 2 is set lower than that of the oscillating circuit 1 here, the bias VS in the test mode is set smaller than that of normal time and the threshold voltage of the memory element becomes low so as to make high efficiency test possible.

Abstract: PURPOSE:To shorten the distance between crankshafts and enable the sure transmission of motive power through a compact size and low weight, by forming the webs of the crankshafts with gears, and enagaging the gears with each other to transmit the motive power. CONSTITUTION:A fresh mixture supplied from an intake passage is compressed in a crankcase 24 as crankshafts 6, 11 rotate and pistons 5, 5 move down. At the same time, combustion gas is discharged from exhaust passages 26, 27. The compressed mixture is supplied into combustion chambers in a cylinder block 3. Since the same crankcase 24 is provided for both cylinders 1a, 1b, the mixture is charged into both the cylinders uniformly under equal pressure. As the pistons 5 move up, the mixture is compressed in the cylinders 1a, 1b for explosive combustion. Such strokes are repeated. According to this constitution, the distance between the crankshafts 6, 11 is shortened, the engine is made compact, and a separate system for transmitting motive power between the crankshafts is not needed. Therefore, the weight and the fuel consumption are reduced.

Title: Method for leaching vanadium contained in used catalyst
Inventor: KIRISHIMA KENJI
IPC: C22B34/22
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To selectively recover vanadium at a good leaching rate without the execution of a high-temp. treatment by bringing used vanadium-contg. catalysts into contact with sulfuric acid in the presence of metal aluminum to leach vanadium. SOLUTION: The vanadium is leached by bringing the used catalysts contg. the vanadium into contact with the sulfuric acid in the presence of the metal aluminum. If the used catalysts contg. the vanadium contain an oil-component, the catalysts are previously subjected to a pretreatment to remove the oil- component by oxidation roasting at about 300 to 690 deg.C. The amt. of the sulfuric acid to be used is satisfactory if the amt. is kept below 4.8 times the weight of the vanadium element included in the used catalysts. The metal aluminum is made to exist preferably at 0.5 times the weight of the vanadium element included in the used catalysts and at 100g or below per 1 liter leaching liquid.  While the vanadium is included in the form of pentad oxide in the used catalysts, the pentad oxide is reduced to quadrivalent oxide by the reducing power generated at the time the metal aluminum dissolves, by which the solubility into the sulfuric acid is enhanced.

Title: Safety combustion device
Inventor: KITAMURA JIYUNICHI
IPC: F23N1/08
Filed: 1983-08-23
Abstract: PURPOSE:To ensure an improved safety, by arranging such that a fuel supply to a burner is automatically interrupted in the case of burner unignited or flame extinguished during combustion, and the burner is unable to be ignited or burnt unless unburnt gas is exhausted from a device after the lapse of preset time. CONSTITUTION:By opening a hot water feed cock 9, a water flow switch 9 is turned ON and a condenser C increases its voltage higher than a reference voltage. A comparator 12 outputs an operation signal to a combustion actuation circuit 11 to effectuate an ignition trial a1. In the case of ignition failure, however, a first switch circuit 16 is turned into a high-voltage state while a second switch circuit 17 is in turn maintained in a low-voltage state. An electrical discharge is thus effectuated via a second discharge circuit 14, so that the voltage of condenser C may be reduced to zero. The charge of condenser C is started after the condenser C is fully discharged and consequently if an operator knows the ignition failure and attempts to reignite, the ignition trial a1 is effectuated after a prepurge a2 is finished, provided that the water flow switch 9 is turned ON prior to the finish of prepurge a2.
