IPC: B01D35/14
Filed: 1989-11-07
Abstract: PURPOSE:To accurately and efficiently control a filter by measuring the pressure difference between the primary and secondary sides of the filter, flow rate on the secondary side and the amt. of liq. passing through the filter in a specified time and reporting the measured values. CONSTITUTION:The liq. pressure P2 on the input side on the filter plate 24 of the filter 20 and the pressure P1 on the output side are measured to control the filter.

Title: Optical fiber angular velocity sensor
Inventor: MIYAZAKI JUNPEI
IPC: G01C19/72
Filed: 1991-11-06
Abstract: PURPOSE:To improve stability, reliability and precision by a method wherein the frequency of a drive signal given to a piezoelectric vibrator is set to be lower than any of resonance frequencies in the directions of the radius, the axis and the circumference of the piezoelectric vibrator. CONSTITUTION:By impressing an alternating-current signal on electrodes 1 and 2 of a cylindrical piezoelectric vibrator 3, the vibrator 3 is made to expand and contract in three directions of the radial direction (arrow 13), the axial direction (arrow 14) and the circumferential direction (arrow 15) and generates vibrations. Out of the vibrations in these three directions, the resonance frequency in the radial direction is the lowest and inversely proportional to the sum of an inside diameter D1 and an outside diameter D2. When a modulated set frequency fm is set at a value being lower by several hundreds of heltz to several kilohertz than the resonance frequency in the radial direction, accordingly, changes in a modulation efficiency and others due to a change in the resonance frequency of the vibrator 3 and a change in a Q value which are caused by a temperature change, a manufacturing error, a change in an external pressure, etc. become remarkably smaller, in this region, than the ones in the case when the modulated frequency fm is made to accord with the resonance frequency. Although the modulation efficiency lowers on the occasion, it is supplemented by increasing the number of windings of an optical fiber 4.

Title: Taking-out device for molded product
Inventor: SHIMIZU HITOSHI
IPC: B29C45/42
Filed: 1989-11-10
Abstract: PURPOSE:To make identification of defective product at the first stage easy and inspection of quality of a molded product easy even at an appropriate time, by a method wherein the molded product introduced into a recovery chamber by passing through a transport pipe from a taking-out head by receiving suction force by a decompression device is dropped and held within a recovery holding vessel by discharging through an opening and closing lid. CONSTITUTION:A molded product held in one side mold of a resin molding machine is introduced into a recovery chamber 50 by passing through a transport pipe 40 through a taking-out head 30 by receiving suction force with a decompression device 60. When introduction is detected by an optical sensor 45, sucking force becomes not workable by suspending an action of the decompression device 60 and an opening and closing lid 70 on the lower part of a recovery chamber 50 becomes an open state with its own weight. The molded product introduced into the recovery chamber 50 is dropped through the recovery chamber 50, discharged through the open state opening and closing lid 70 and held within a lower holding vessel 80. Since the holding vessel 80 is separate from and independent of the recovery chamber 50, the held molded product can be handle freely. For example, only a defective product at the initial stage can be identified easily and inspection of quality can be performed easily by extracting the molded product at an appropriate time.

Title: Production of alloy and intermetallic compound of pseudosingle domain magnetic material powder
Inventor: ADACHI KINYA
IPC: B22F1/00
Filed: 1994-11-25
Abstract: PURPOSE: To obtain a pseudosingle domain particle powder excellent in magnetic characteristics and durability by subjecting the single domain particles of an alloy exhibiting magnetic anisotropy and an intermetallic compound magnetic material to orientation in the easy axis of magnetization under a magnetic field and then performing pressure molding and sintering at a predetermined temperature. CONSTITUTION: An alloy or an intermetallic compound is crushed down to the single domain particle size and then it is molded in a magnetic field to produce a green compact where the particles are oriented in the easy axis of magnetization. Subsequently, it is heat treated at the predetermined temperature in order to accelerate the growth of particle and adhesion thereof. When the sintering has progressed, the green compact is crushed again into desired size and subjected to an appropriate chemical or physical treatment thus producing a pseudosingle domain particle powder. Consequently, a powder of pseudosingle domain particle having large particle size can be produced easily.  Since the powder is excellent in oxidation resistance and can be molded easily together with a binder, the magnetic characteristics and durability can be enhanced when the powder is employed as the material of bond magnet.
