Title: Device for magnetic recording
Inventor: SAKAKI TERUO
IPC: G11B5/48
Filed: 1984-04-20
Abstract: PURPOSE:To permit easy working and adjustment with the decreased number of parts and to make a device smaller and more compact by the constitution in which just one pair of head blocks constituted integrally with a main magnetic pole and auxiliary magnetic pole are disposed in a way so as to face the recording films. CONSTITUTION:The main magnetic pole 11-1 is held in proximity to a vertical magnetized film 12-1 and while the opposite block (the auxiliary magnetic pole 15-2, the main magnetic pole 11-2 and coil 16-2) is held detached from a medium, a signal is applied to the coil 16-2 to operate the head as an auxiliary magnetic pole and recording is executed by the main magnetic pole 11-1 in the case of performing recording and reproducing to the recording films 12-1, 13-1 on a medium substrate. The signals of the films 12-1, 13-1 are detected by the main magnetic pole 11-1 and are taken out of the coil 16-2 of the opposite head block in the case of reproduction. The main magnetic pole 11-2 and another recording films 12-2, 13-2 are substantially spaced from each other and therefore generation of a problem such as overwrite is obviated.

Title: Detector for position of excavator in open caisson method
Inventor: TANAKA KAORU
IPC: G05D3/12
Filed: 1993-03-12
Abstract: PURPOSE:To accurately detect the position of an excavator in a caisson. CONSTITUTION:A reversible counter 132 counts output pulses from a rotary encorder 130 attached to a driving wheel for an excavator and sents its counted value to an operating device 134 for the position of traveling. On the basis of the counted value from the reversible counter 132, the operating device 134 finds the position where the excavator travels and outputs it, and simultaneously rewrites positional data on a storage 136. When a MR sensor 140 detects a magnet 142 provided along a rail for the traveling of the excavator, the MR sensor 140 inputs it to a soft counter 146 through a detector 144 for the direction of the traveling. On the basis of output pulses from the MR sensor 140, which are counted by the soft counter 146, an operating device 148 for actual position retrieves a table 150 for positional data, finds the actual position of the excavator and inputs it to a comopensator 152 for detected position. The compensator 152 clears the reversible counter 132 and compensates an operated value by the operating device 134 for the position of the traveling.

Title: Orthogonally phase shifting circuit
Inventor: NISHIJIMA KAZUNORI
IPC: H03H11/20
Filed: 1990-03-28
Abstract: PURPOSE:To obtain a signal phase-shifted accurately by 90 deg. without being affected by dispersion in components or temperature change by providing a phase detection circuit adjusting the level of a phase control signal when a phase shifting angle is deviated from 90 deg.. CONSTITUTION:A phase detection circuit 3 detects a phase difference between the input signal Vi and the output signal Vo of a phase shifting circuit 1 inputted via an amplifier 2 and increases the level of an error signal Vo when the phase difference is larger than 90 deg. and decreases the level of the error signal Vo when the phase difference is smaller than 90 deg.. When the phase difference is larger than 90 deg., for example, a control signal Vc whose level is increased is given, the capacitor of a voltage variable capacity diode Cv is small and the phase angle approaches 90 deg.. Thus, an output signal Vo whose phase shifting angle is 90 deg. appears at an output terminal To at all times. Thus, the phase angle of 90 deg. always accurate independently of dispersion in components or temperature change is maintained.

Title: Current mirror circuit
Inventor: SHINOMIYA KOUJI
IPC: H03F3/347
Filed: 1982-05-10
Abstract: PURPOSE:To attain a current mirror circuit in which the phase compensation is performed easily and the stable operation is obtained, by reconstituting the circuit in which transistors (TR) being the current mirror circuit components are changed into common base constitution with collector resistors of the TRs selected as low as possible. CONSTITUTION:A minimized input bias current is attained by the constitution of input circuit MOS TRs of a differential amplifying circuit OP. Since an input current to an inverting input is brought to <=0.1pA by using the differential amplifying circuit OP, the current is regarded as almost zero. Thus, a current Ii inputted from an input terminal 1 is regarded as a collector current Ic of a TRQ1. Further, since a power supply EA is connected to a noninverting input of the differential amplifying circuit OP, the collector potential of the TRQ1 is set freely with a voltage of the power supply EA with a negative feedback operation. That is, the current error due to the base width modulation effect of the TRQ1 and TRs the output accuracy of which are desired high, is neglected.

Filed: 1992-04-01
Abstract: PURPOSE:To prevent the formation of blocking and to satisfactorily produce fine metal powder by specifying a vertical distance from the lower end of an ejector spurting a high velocity jet to the primary atomization point. CONSTITUTION:Molten metal M flows down as a columnar molten metal flow of a small diameter M' from a molten metal nozzle 2 in the bottom part of a tundish 1 and is atomized by spurting a high velocity jet to it from a jetting nozzle 3. At this time, the jet nozzle surrounds the columnar molten metal flow M' in the form of a ring and a part of the inner wall 4 from the upper surface to the ejector of the jet nozzle 3 is made conical surface 4', causing the primary atomization action in the neighborhood of the apex of the cone to happen. The vertical distance from the primary atomization point P1 to the lower end of the ejector 5 of the nozzle 3 is specified so that it may be 40-85% of that from the lower end of the ejector 5 to the intersection point P2 of the high velocity jets (the secondary atomization point). Thereby the formation of blocking in an ultra high velocity atomization method is prevented and fine powder is effectively produced.

Title: Separating and removing method for fine particle suspended in fluid
Inventor: HARA FUJIO
IPC: B01D29/25
Filed: 1978-06-29
Abstract: PURPOSE: To make it possible to remove sludge independently of the particle size of the sludge, by dividing a centrifugal separating chamber from a separating chamber by a partitioning plate having through-holes, and by connecting a cylinder having an upper opening to a discharging pipe.  
     CONSTITUTION: While a liq. contg. sludge etc. rising helically in a centrifugal separating chamber 5, the sludge etc. stays in the chamber 5 for a long time because its specific gravity is larger than that of the liq., so that gravity acts on the sludge to make the sludge fall against the rising liq. At the same time, the number of helical rotation of the sludge is increased to meke the centrifugal force energy greater. The sludge is helically floated along the inner surface of the cylindrical partitioning plate 11 and is pushed out by way of through-holes 10 to a separating chamber 9, where the sludge falls rapidly to a precipitating chamber 12 because the helical flow of the sludge is nearly interrupted by the partitioning plate 11, and deposited on the bottom. Hereby the liq. at the upper part of the centrifugal separating chamber 5 becomes clear, and flows away through an opening 13 of the cylinder at the central part to a discharging pipe 13.
