PURPOSE:To attenuate noises generated by impingement between a movable iron core and a core receiver, by providing a vibration damper between a yoke and a coil. CONSTITUTION:A solenoid is provided with a vibration damper 10 between the inner face of a first yoke 2 and a coil 5. For example, after this vibration damper is inserted between the coil 5 and the first yoke 2, the first and second yokes ...

A method and apparatus for removing carrier liquid from solids particles separated from a liquid slurry in a decanter-type centrifuge, a further liquid is introduced into the bowl which is both immiscible with and of higher specific gravity than the carrier liquid to establish at the periphery of the bowl a body (42) of this further liquid defining a transfer zone (46) disposed radially outwardly ...

PURPOSE:To detect an infinite loop having runaway of software by applying interruptions periodically with a pulse signal having the time width longer sufficiently than the execution continuing time for a normal interruption and a cycle shorter than the normal interruption executing time. CONSTITUTION:An FF6 is reset and then set again immediately with the output of an interruption waiting instruct...

The present invention provides a method of producing articles containing cement and reinforcing vegetable fibres. Hitherto, the fibres had to be treated chemically in order to ensure sufficient bonding between the cement and the fibres. The present invention removes the need for the chemical pre-treatment of the fibres and involves a two stage process of mixing the cement powder, water and the fib...

PURPOSE:To prevent the system breakdwon of a multiprocessor by reading out the correct data from the control data of the own CPU when an error is detected with the control data of another CPU and writing the correct data on a control memory of said faulty CPU. CONSTITUTION:An error arises on the control data of a CPU1; while a CPU2 is in normal working. In such a case, the CPU1 stops immdiately it...

PURPOSE:To prevent a shortcircuit malfunction due to the contact of leads with a metal plate in case of sealing by providing an insulator film on the surface of the metal plate buried in a sealing resin so as to accelerate thermal conduction. CONSTITUTION:A chip 1 is bonded to a die pad 2, the inner ends of leads 3 and a gold wire 4 are electrically connected, a metal plate 5 to accelerate thermal...

PURPOSE:To prevent a shortcircuit malfunction due to contact of leads with a metal plate in case of sealing by providing an insulator film on the back surface of the lead of a resin-sealed semiconductor device buried with the metal plate in a sealing resin so as to accelerate thermal conduction. CONSTITUTION:A chip 1 is bonded to a die pad 2, the inner ends of leads 3 and a gold wire 4 are electri...

PURPOSE:To improve heat sink characteristic with a simple structure by bonding a paste material which has a thermal conductivity higher than an enclosure sealing resin material on the back surface of a semiconductor chip placing plate. CONSTITUTION:A semiconductor chip 1 is secured to the surface of a chip placing plate 2, electrically connected by fine gold wirings 4 with the inner ends of leads ...

The invention relates to a method for preparing inner ester ganglioside derivates which comprises: (a) dissolving a ganglioside or a mixture of gangliosides obtained from a mammal in a non-aqueous organic solvent; (b) converting the carboxylate groups in the gangliosides to carboxyl groups or a salt thereof by means of ion exchange; and (c) reacting the resultant ganglioside or mixture of gangl...

Compounds of the formula wherein R1 is hydrogen, an optionally substituted aromatic hydrocarbon radical, an aralkyl radical or an optionally substituted aliphatic hydrocarbon radical having up to 45 C atoms, R2 is an optionally substituted aromatic hydrocarbon radical, an aralkyl radical or an optionally substituted aliphatic hydrocarbon radical having 5-50 C atoms, X is O, S, NH or NR...

A computer for calculating the similarity between first and second patterns, each represented by a sequence of feature vectors, comprises a calculating circuit for calculating a weighting factor from feature vectors in the first pattern, a weighting circuit for applying the weighting factor to the feature vectors of the second pattern to calculate an estimated vector for the second pattern, and a ...

Preparing olefins by mixing heavy petroleum oil (i.e. crude oil and atmospheric pressure and reduced pressure residual oils) with superheated steam in an atomizer (5) with a steam-oil ratio of from 2 to 7, and feeding the resulting mixture into an indirectly heated reaction tube (6) so that the temperature at the outlet (8) of the reaction zone is from 700 to 950 DEG C. The residence time of the m...
