Patent JP-H04247606-A (JP)
Title: Focus-orientation type disk magnet and magnetic field orientation molding device
Inventor: NAKATSUKA SATORU
IPC: H01F41/02
Filed: 1991-02-01
Abstract: PURPOSE:To improve a surface magnetic field on a substantial active surface of a disk magnet by controlling orientation of magnetic powder in a magnet material. CONSTITUTION:While a synthetic resin magnet material which has been introduced into a disk cavity 1 by extrusion molding is being softened, a magnetic field is applied to the magnet material, whereby lines of magnetic force transmit to focus to a center ring region of a main pole side track in the disk cavity 1. Therefore, an axis of easy magnetization of magnetic powder in the magnet material is oriented to focus to the center ring region of the main pole 3 side track along a direction of the lines of magnetic force to provide a focusing type disk magnet. From an aspect of a metal magnetic circuit, magnetic pole width is made narrower than cavity width with a center ring of a side track as the center on a small area side where a magnetic flux should be converged, while on a magnetic field applied surface of a magnetic pole on the opposite side with a large area, it is essential to have the magnetic pole width equal to or wider than the cavity width.

Title: Liquid discharging instrument
Inventor: MASUYAMA KESAO
IPC: B65D83/00
Filed: 1990-02-14
Abstract: PURPOSE:To quantify discharge easily by means of a simple constitution by using a collision sound at a time when ratchet teeth are mutually brought near and collide by the use of an elastic member and by moving a push rod forward only when a rotating base is intended to make position rotation. CONSTITUTION:When a rotating base 60 makes positive rotation from the initial position, the state in which the projection 62 of the rotating base 60 is abutted against a stopper 15, a push rod 20 is moved forward while being revolved in response to the angle of rotation of the rotating base 60 by the screwing section of a rod holder 30 because rear second ratchets 52, 61 are brought to an engaging state under the non-engaging state of front first ratchets 41, 51, and a liquid is discharged by a pushing valve 21. Since the collision sound of 'click' due to the mutual collisions of the ratchet teeth 41, 51 is generated every time a front slider 40 is slid forward and returned to an original position by the first ratchets 41, 51, discharge can be determined by the number of the collision sounds, thus easily attaining the quantification of discharge.

Title: Voltage controlled oscillator circuit
Inventor: YAMAZAKI KIYOHIKO
IPC: H03L7/183
Filed: 1990-02-13
Abstract: PURPOSE:To prevent the influence of external noise onto process fluctuation and the increase in jitter by detecting the level of an input voltage with a voltage detection circuit and operating a control current circuit with a detection signal. CONSTITUTION:When an input voltage is given to this voltage controlled oscillator circuit 110, a voltage detection circuit 160 compares 1st and 2nd reference voltages with the input voltage and the detection signal of H or L level in response thereto is outputted to a constant current circuit 170. Then the constant current circuit 170 is turned on or off according to the inputted detection signal to change the operating current of the voltage controlled oscillator circuit 110 by a prescribed current. Thus, when the input voltage is low, the oscillating frequency is low and when the input voltage is high, the oscillating frequency is high and a hysteresis characteristic is generated in the input voltage versus oscillating frequency characteristic and the oscillating frequency range is made broader without increasing the voltage frequency conversion gain. Thus, the effect of external noise and the increase in jitter are prevented.

Title: Separation of insoluble solids from liquefied hydrocarbon
Inventor: PIITAA JII GUROENEUEKU
IPC: C10G21/00
Filed: 1983-02-28
Abstract: A process for the separation of solids from liquid hydrocarbons in which liquid hydrocarbons comprising oils, asphaltenes and pre-asphaltenes containing insoluble solids are contacted with a volatile solvent compatible with the liquid hydrocarbons for solubilizing said oils, asphaltenes and pre-asphaltenes. The liquid hydrocarbons containing solids are contacted with the volatile solvent in stages to form a carrier solution which preferably is displaced by the volatile solvent, preferably by a countercurrent or crosscurent contacting mode, to produce a slurry of insoluble solids with volatile solvent substantially free of the said liquid hydrocarbons, to permit a separation and removal of said insoluble solids by gravity settling, preferably under centrifugal forces, such that a minimum of interstitial liquid containing a minor amount of the liquid hydrocarbons is discharged with the insoluble solids. The interstitial liquid, composed largely of the volatile solvent, is substantially recovered from the solids by evaporation. The liquid hydrocarbons, including substantially all the asphaltenes and pre-asphaltenes, are thus effectively separated from the solids and can be in turn separated from the volatile solvent for conventional processing. High losses of the asphaltenes and pre-asphaltenes inherent in known processes, particularly for low rank coals such as lignite coals, are avoided.
