Title: Apparatus for filtering petroleum
Inventor: ISHINO TAKESHI
IPC: F02M37/22
Filed: 1982-01-11
Abstract: PURPOSE:To obtain a filter apparatus excellent in durability, by using a rubber magnet in which a ferrite powder having a coupling agent adhered to the surface thereof is mixed as a filter to prevent the deterioration of rubber. CONSTITUTION:After a titanium coupling agent such as isopropyl triisostearoyl titanate is mixed with a ferrite powder or a mixture prepared by mixing vinyltriethoxysilane in a solvent is dripped to the ferrite powder to be stirred therewith, the treated ferrite powder is dried to adhere the coupling agent to the surface thereof and mixed in rubber along with a vulcanizing agent. The prepared rubber compound is molded into a sheet to be subjected to vulcanizing treatment and, after the resulting vulcanized sheet is subjected to magnetizing treatment by an electromagnet, it is molded into a desired shape to prepare a filter. As is apparent from the foregoing, because this filter does not contain a plasticizer, the elasticity thereof is not lost even in a gas oil and the durability thereof is enhanced. in addition, in place of rubber, a flexible plastic can be also used.

Title: Rotary encoder
Inventor: SOEJIMA KENJIRO
IPC: G01D5/245
Filed: 1992-01-10
Abstract: PURPOSE:To prevent a failure from occurring by retaining a magnetic field spacing which is formed by the magnetization surface of a magnetic circular plate and a magnetic detector, to be uniform constantly. CONSTITUTION:A cylindrical part 31 of a retention body 3 is retained nearly concentrically within a cylindrical part 21 of a main body 2 by a plurality of leaf springs 4 9 that it can be rocked. Therefore, when a rotary axis 7 is inclined due to deviation, etc., between the rotary axis 7 and the axis of a specimen, the leaf springs 4 are deformed and then axis deviation is absorbed while the retention body 3 rocks following inclination of the rotary axis 7. On the other hand, a magnetic circular plate 5 is engaged into and is fixed to a cylindrical part 31 of the retention body 3 by a bearing 6 and also a magnetic detector 8 is provided at a cylindrical part 31 of the retention body 3 in one piece. Therefore, the relative position between the magnetic circular plate 5 and the magnetic detector 8 does not change and a magnetic field spacing which is formed by a magnetization surface 53 and a magnetic resistance element 80 is always retained to be constant regardless of the axis deviation.

Title: Leak diagnostic device for evaporative fuel processor
Inventor: OKUMA SHIGEO
IPC: F02M25/08
Filed: 1999-01-08
Abstract: PROBLEM TO BE SOLVED: To shorten the time for leak diagnostic in evaporative fuel processor. SOLUTION: After an engine stop, an air pump 13 is actuated and a directional control valve 14 is changed over to connection with the air pump 13, so that the air the air pump 13 force-feeds flows through the directional control valve 14 and into a new charge inlet 9 of a canister 7 which feeds it into purge lines 6 and 10. The air pump 13 is initially driven on a high driving voltage V2 so as to have an accordingly raised feed rate. The driving voltage of the air pump 13 is next changed down to a normal driving voltage V1, after which the operating current value of the air pump 13 is measured as a leak level. The obtained leak level is compared with a determination level. A leak level not larger than the determination level triggers a leak decision.

Title: Method and apparatus for inserting code into television signal
Inventor: EMIRU PENCHIEFU BURADOKOFU
IPC: H04N5/278
Filed: 1989-01-09
Abstract: PURPOSE: To cope with every television signal encoding standard and to prevent degradation in television signal quality after a code has been inserted by forming a level value of a code signal to a value which is lower than or equal to the difference between a luminance level of the code inserted into a television image and an instant luminance level of the television signal and adding the television signal and the code signal together. CONSTITUTION: The code is inserted into the television signal by executing the addition of the television signal and the code signal together. Before the addition, the code signal is formed so that its value B is always set lower than or equal to the difference between the luminance level E of the code inserted into the image and the instant luminance level VA of the television signal. For example, a first input terminal of an adder 1 is connected to an output terminal of a DC level fixing unit 3, and a second input terminal is connected to the output terminal of an adder 11. Consequently, the quality of the television signal does not change, and coping with every color standard system is enabled by making it hardly affected by a nonlinearization processing or frequency conversion processing, when the code is inserted into the television signal.

Filed: 1980-01-14
Abstract: PURPOSE: To enable to make zero point correction automatically without stopping a scale, by inhibiting the supply of object to a measuring vessel with a given zero point corrector and correcting the output of a weight detector to zero.  
     CONSTITUTION: When a switch 25 is closed and a start memory 32 is set, the output of a NOT circuit 34 is zero to inhibit the operation of a supply gate 10 and take- in gate 14a. The discharge signal of a combined control section 22 opens a discharge gate 4, a discharge end memory 48 is set, the output is made to 1, and a zero-point correction output generating device 28 is operated. The device 28 detects the output of an addition/substraction amplifier 26 to one end of which the output of a weight detector 18a is fed, and the output in which this is zero is fed to an amplifier 26. In this case, since no material is fed to a measuring vessel 2a, zero correction is made. Thus, the supply of material during the operation of a scale is inhibited to enable zero point correction.

Title: Length measuring apparatus using ultrasonic
Inventor: NOUMI YUUZOU
IPC: G01S7/527
Filed: 1985-01-11
Abstract: PURPOSE:To achieve a higher reliability of measurement, by forbidding the sampling of results of measurement with a time measuring circuit when a reflected wave is not received within a specified time range to remove an abnormal measured value. CONSTITUTION:A probe 11 is driven with a transmitting circuit 12 to transmit an ultrasonic wave. The reflected ultrasonic wave is received with the probe 11, the output of which is fed to a time measuring circuit 14 through a receiving circuit 13. A received wave monitoring circuit 31 monitors the presence of a receiving trigger from the receiving circuit 13 due to the received wave until a fixed time passes after the reception of a transmitting wave and outputs a received wave detection signal when the receiving trigger is inputted. In response to the received signal detection signal, a sample holding circuit 16 starts the sampling of the output from the time measuring circuit 14. In addition, malfunctioning due to a jamming wave can be prevented with a disturbance counter measure circuit 40.

Abstract: PURPOSE:To obtain a lead frame with excellent bonding property by a method wherein layers of an Al alloy containing Si and Fe are cold welded to the two surfaces of a strip shaped Fe core material and is subjected to annealing before it is used to constitute a lead frame for a semiconductor device. CONSTITUTION:Al alloy layers 11b and 11b' containing 0.7-1.5% Si and 0.3- 0.6% Fe are cold welded to cover the both main surfaces of an Fe core stripe 11a.

Abstract: PROBLEM TO BE SOLVED: To reduce driving motive power and to reduce maintenance cost by floating a footboard belt by an air film. SOLUTION: A footboard belt 3 is made to float by forming an air film 13 by delivering compressed air 12 from a pore 10b between an outward side belt 3a lower surface and a frame board 10 upper surface.

Filed: 1992-01-13
Abstract: PURPOSE:To simplify the measurement of lead angle of the tooth section of a gear by detecting the displacement of the side end face of the gear and calculating the rate of change by differentiating the displacement with respect to the pitch of the tooth section. CONSTITUTION:Since a contact terminal 1 is displaced as the side end face G1 of a gear G is displaced, a rotary member 3 is rotationally displaced and, as a result, the displacement of the face G1 of the gear G is detected by means of a digital gauge 4 which is brought into contact with the member 3. In case the displacement of the face G1 exceeds a reference value during the detection of the displacement, a marking member puts a mark. Then the rate of change is calculated by differentiating the displacement of the face G1 of the gear G thus measured with respect to the pitch of the tooth section of the gear G. Then the deflection of the lead angle of the tooth section is estimated from the rate of change.
