Title: Magnet roll
Inventor: YAMASHITA KEITARO
IPC: H01F7/02
Filed: 1992-11-10
Abstract: PURPOSE:To obtain a magnet roll for development which suppresses production of eddy current and can be produced at low cost by forming a sleeve of an aluminum alloy having specified electric conductivity. CONSTITUTION:A permanent magnet member 1 is made of, for example, barium ferrite magnetic material, and is magnetized to have symmetric 8 poles on the outer surface. Then a sleeve 6 is formed by using an aluminum alloy having <=40% electric conductivity of the pure copper and is coaxially assembled with the permanent magnet member 1 to obtain a magnet roll. The aluminum allay having <40% electric conductivity ratio is preferably, for example, A5056 alloy. By this constitution, eddy current generating in the sleeve 6 can be decreased, which prevents generation of heat in the sleeve 6, stabilizes the picture quality, and decreases the driving torque.

Title: Interplace system
Inventor: INOUE TAKASHI
IPC: H04N3/00
Filed: 1986-12-16
Abstract: PURPOSE:To obtain a picture with least influence of noise by constituting the interlace display circuit of a cathode-ray tube displayer so that a constant current source for superposing vertical deflection currents which is operated by a decision signal representing an odd-number field or an even-number field, is connected with a deflection DC coil to deflect the output of a vertical deflection circuit. CONSTITUTION:The titled system is constituted of an odd/even number field decision circuit 1, the vertical deflection DC current superposition circuit 2 that is driven by a decision signal outputted by the former circuit 1, and a vertical amplitude detection-amplification circuit 5 from which provides such a signal to correct a superposed current to satisfy the vertical size of the screen so that the interlace ratio comes constant even if said size varies. With this constitution, an interlace correction current outputted by the circuit 2 is superposed on a current through the deflection coil during an even number field period or an odd-number field period. Thus either an odd-number field or an even-number field is shifted upward or downward for a length in vertical deflection direction equivalent to half a horizontal scanning period. In such a way, an interlace display can be achieved.

Title: Water recovering method of sewage treatment water
Inventor: MATSUI KATSUNORI
IPC: C02F1/58
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To recover a fresh water from a sewage treatment water and to make the most use of water resource by removing COD components and BOD components in a concentrated water, which is concentrated by a desalting reverse osmotic membrane, by a low pressure reverse osmotic membrane and discharging the water with a quality within the effluent standard directly to the outside to facilitate the treatment of the concentrated water. SOLUTION: A supply water 1 consisting of the sewage treatment water is supplied from a supply line 5 and, in the desalting reverse osmotic membrane 2, a desalted water 3 is separated by impressing a pressure higher than the osmotic pressure on the supply water 1 side. The desalted water 3 is separated from salt matter, the COD components and the BOD components in the supply water and utilized as the fresh water and reutilized for sewage treatment or industrial water. The concentrated water 4, in which almost all of the salt matter, the COD components and BOD components remain, is introduced into the low pressure reverse osmotic membrane 8 through a concentrated water line 7 and a COD/BOD-removed water 9 is separated by pressurizing. The COD/ BOD-removed water 9 has a quality within the effluent standard value and is discharged as it is.

Title: Air conditioner
Inventor: SUMITANI SHIGETO
IPC: F25B1/00
Filed: 1987-11-30
Abstract: PURPOSE: To operate an air conditioner having a refrigerant heating path for cooling with a low load when the outside air temperature is low, by controlling the valve travel of a flow control valve provided to a discharge gas by-pass path on the upstream side of a refrigerant heater. CONSTITUTION: In the refrigerating cycle of an air conditioner, a flow control valve 31 the valve travel of which can be controlled freely is connected to a discharge gas by-pass path 32 which communicates the discharge side of a compressor 21 with the upstream side of the refrigerant heater 30 of a refrigerant heating path 28. Therefore, when the air conditioner is operated for cooling with a low load when the outside air temperature is low, the valve travel of the flow control valve 31 is controlled to a required value by means of a control signal from a controller 36. Accordingly, part of a discharge gas from a compressor 21 is branched to the by-pass path 32 under the guidance of the valve 31 and another part of the discharge gas is blocked by a closed two-way valve 29, flows in the heating path 28, and returns to the compressor 21 through the refrigerant heater 30.  Consequently, the suction pressure of the compressor 21 is secured and the cessation of operation of the air conditioner is prevented.

Title: Absorbing article
Inventor: KANAI TAEKO
IPC: A61F13/15
Filed: 1994-12-02
Abstract: PURPOSE: To eliminate the trouble caused by the stretching of an elastic material at the time of the processing of a product and to enhance the stability of product capacity by using a composite material formed by fixing an elastic material and a non-elastic material using a curable adhesive cured by the application of energy from the outside as an elastic member. CONSTITUTION: A composite material 1 has an elastic material 2 in a stretched state and a non-elastic material 3 fixed to the single surface of the elastic material 2 through an adhesive 10 formed by arranging a non-curable adhesive 11 and a curable adhesive 12 in predetermined patterns while the stretched state of the elastic material 2 is kept. The elastic material 2 becomes freely stretchable in a region other than the bonded part of the non-curable adhesive 11 by the application of energy. Since the elastic material 2 is fixed to the non-elastic material 3 through the adhesive layer 10, the expansible force of the elastic material 2 is not developed as the whole of the composite material even in such a state that the elastic material 2 is stretched and, therefore, this article can be handled in the same way as a usual member having no expansible force.

Abstract: PURPOSE:To lighten a shift part and to remove the telescopic rod for a long mandrel by providing a means to supply hydraulic oil for a telescopic device for a mandrel fitted on the point of a mandrel shaft through a driving device. CONSTITUTION:A 1st, a 2nd, a 3rd valve body 25, 32, 33 are engaged by moving a mandrel shaft on a driving device side respectively with a 4th, a 5th, a 6th valve body 43, 46, 47 in a coupling 16 on a mandrel shaft side. Of each valve body, the 2nd valve body 32 and the 5th valve body 46 are brought into pressure contact with each other, the 3rd valve body 32 and the 6th valve body 47 are brought into pressure contact with each other and flow paths are communicated with each other. When a coupling 16 at the point of the mandrel shaft is shifted so that it is departed from the coupling 10 of the output shaft of the driving device, each valve body closes the flow paths instantly by the action of each compression spring. Thus, the shift part is lightened in weight and the telescopic rod for the long mandrel can be removed.
