IPC: C09D7/12
Filed: 1986-09-19
Abstract: PURPOSE:To obtain magnetic semiconductor globular fine particles which have no magnetic anisotropy and can be applied to a substrate to realize a magnetic recording medium with excellent magnetic characteristics and which can produce compound component gas of a ferrite component and a ceramic component as CVD materials by making solid solution of the ceramic component and the ferrite component uniformly and foriming the solid solution into globular fine particles. CONSTITUTION:Magnetic semiconductor particles which are obtained by making uniform solid solution of a ceramic component and a ferrite component and forming the solid solution into globular fine particles are employed. Powder which is composed of ferrite-ceramic composite particles which are obtained by coating the surfaces of ceramic fine particles with ferrite crystals are heated and melted at a high temperature and chilled by high speed flame-coating on a cooling material to form solid solution globular fine particles. For instance, the powder composed of ferrite-ceramic composite particles (the average particle size is 0.6 mum) which are obtained by coating the surfaces if the ceramic fine particles with the crystals of ferrite are reduced and melted at a high temperature in a plasma flame.-coating apparatus and the melted powder is made to collide against water or a cooling plate with a high speed (about 30 m/sec) to obtain amorphous magnetic semiconductor globular fine particles in which the ceramic component and the ferrite component are coupled with each other.

Title: Vertical shaft pump
Inventor: TAMURA IKUJI
IPC: F04D29/44
Filed: 1989-08-25
Abstract: PURPOSE:To securely prevent the vibration of a vertical shaft pump at the time of sucking water by setting the discharge port of a tank device, lower than the lowest water level, which receives water rising from the hanging pipe portion of the other side of a branch pipe at a position lower than the level of a turn-back portion. CONSTITUTION:When the water level of a well P descends to release the water sealing at the air introduction portion 7 of a branch pipe 3, water sucked up in a hang pipe portion 10 rises due to the negative pressure of an impeller chamber 6 to be received in a tank device, but the water is not introduced in the impeller chamber 6. At this time, as the discharge port of the tank device is set lower than the lowest water lever, there is no event such that air enter to the branch pipe 3 from the discharge port of the tank device before the air enters from the air introduction portion 7 to make the interception of pumping, secure pumping operation can be conducted even at the lowest water level without vibration due to the enter of the air.

IPC: H03H17/02
Filed: 1985-10-04
Abstract: PURPOSE:To shorten a time required for the addition of floating point by normalizing only the finally accumulated result. CONSTITUTION:The exponential part data out of an output of an input register 71 to which accumulated output data are inputted from a double precision register 6 are applied to a subtractor 73 and the mantissa part data are applied to a maximum inverted code bit detecting circuit 72 and a shifter 74. The circuit 72 outputs a difference between the succeeding digit of a code bit and the digit of a maximum inverted code bit. The subtractor 73 subtracts the output of the circuit 72 from the exponential part data of the input register 71. The shifter 74 shifts the mantissa part data of the input register 71 left by regarding the output of the circuit 72 as a shifting variable. An output register outputs floating point data consisting of (e+2n-1) bits obtained by assigning an output consisting of (e) bits from the subtractor to the exponential part and an output consisting of (2n-1) bits from the shifter 74 on the basis of the outputs of the subtractor 73 and the shifter 74.

Title: Ecl circuit
Inventor: KURISU MASAKAZU
IPC: H03K19/086
Filed: 1991-08-30
Abstract: PURPOSE:To improve pull-up and pull-down delay times by replacing one of load resistors with an inductance and coupling the inductance with a constant current source of an emitter follower through mutual inductance. CONSTITUTION:One of load resistors of the ECL circuit is replaced with an inductance L1 and an inductance L2 is inserted between a base of a constant current transistor(TR) Q5 of an emitter follower and a constant voltage source VCS2. In this case, an electromotive force shown in equation is induced by a mutual inductance M between L1 and L2. When an input changes from a high level (HL) to a low level (LL), th relation of V2<0 is in existence from equations II, III. Thus, the TR Q5 is turned off and an emitter current of the TR Q4 is an output and used for charging a load capacitance. As a result, a pullup delay time to change the output from into HL is reduced. On the other hand, as soon as the input changes from LL to HL, the relation of V2>0 is in existence and the TR Q5 is turned on and the charge in the load capacitance is extracted to reduce the pull-down delay time.
