Title: Production of magnetic recording medium
Inventor: MORI TAKAHIRO
IPC: G11B5/84
Filed: 1989-04-26
Abstract: PURPOSE:To prevent the surface of a magnetic layer from being scratched by fixing specified diamond abrasive grains on a substrate by electroplating and rotating a cylindrical grindstone with the surface roughness specified to grind the surface of the magnetic layer. CONSTITUTION:The magnetic recording medium 2 (original sheet for 8mm video tape) is rewound from a magnetic recording medium rewinding roll 1 is cut to a width of 8mm by a slitter 6. The video tape is sent to an electrodeposition diamond grinding wheel 7 and ground. In this case, the diamond abrasive grains having 1-20mum average particle diameter are fixed on the substrate by electroplating, and a cylindrical grindstone with the surface roughness Ra controlled to 0.2-1.5mum is rotated to grind the surface of a magnetic layer 2. Consequently, since the amt. of protruding abrasive grains is increased and the sharpness is improved, the surface of the magnetic layer 2 is prevented from being scratched.

Filed: 1986-05-12
Abstract: PURPOSE:To enable liquid to be conveyed in a state in that it has high purity and is extremely clean and to enable the liquid to be conveyed by selecting automatic and manual operation, by a method wherein a cover body having a liquid sucking and discharging means is engaged with a bellows port part made of soft synthetic resin. CONSTITUTION:In case liquid is automatically conveyed with the aid of a pump can 1, compressed air is first fed in an airtight chamber 6c of a can body 6 through a feed valve 16. A base plate 9 secured to a bellows container 2 is pushed upward through the pressure of compressed air to forcibly contract the bellows container 2. Secondly, the compressed air in the can is exhausted through an exhaust valve 17 to expand the bellows container 2. In this case, an internal pressure in the bellows container 2 is decreased, and liquid is sucked from a suction valve 3 secured to a cover body 5. When the internal pressure in the bellows container 2 is increased, the liquid is discharged from a discharge valve 4. Meanwhile, in case the liquid is manually conveyed, the bellows container 2 taken out of the can body 6 is expanded or contracted by hands to discharge or suck the liquid.

Filed: 1980-08-09
Abstract: PURPOSE:To increase a corona discharge starting voltage and to avoid the noise generation even through the corona discharge is generated at the outside of a bushing, by coating a conductive material on the inside of the bushing wherein a Hall element is enclosed, and grounding said material. CONSTITUTION:The bushing 1 has a cylindrical inner space. One end of the bushing is opened and the other end thereof is closed. Coating of the conductive material 9, which is grounded through a conductive lid 6 and a lead wire 10, is applied on the inside of the bushing 1. A horseshoe shaped magnetic core 3 is provided at the upper part of said bushing 1 so that an electric line 2 is enclosed and the core is freely attached and detached.

Title: Inspection method of curved magnetic tape
Inventor: MARUMO MUTSUO
IPC: G11B5/84
Filed: 1979-08-28
Abstract: PURPOSE: To enable quick inspection with high accuracy, by reading out the information recorded at the write-in section through the tape guide different in the guide interval, detecting the shift of the readous timing between the bracks at both the sides of tape and discriminating the curved degree of tape through the size of shift.  
     CONSTITUTION: The two peak detection circuits 1, 2 detect the peak value of the readous signal of the 1st and 7th track t 1 , and t 7  for example. The pulse signal sets the discriminated time in FF7 via the OR gate 5, one-shot multivibrator 6. On the other hand, the logical product of the Q output is output from the NAD gate 8 via FF3, 4 for the signal at the detection circuits 1, 2. When the skew value of the tracks t 1  and t 7  is within the discrimination time of the one-shot multivibrator 6 and the output of the AND gate 8 is 1, no error signal is output from the Q output of FF7. If the output of the AND gate 8 is 0, error signal is fed at FF7 via the inverter 9. Thus, the degree of curve of tape can quickly be inspected with high accuracy.

Inventor: OCHIAI IZUMI
IPC: F04C27/00
Filed: 1978-09-08
Abstract: PURPOSE: To raise the efficiency of compression by maximizing sealing effect by producing labyrinth effect by providing plural grooves along lap winding form in the lap end portion.  
     CONSTITUTION: By providing the plural grooves 14 along lap winding form in the end portion 11 of the lap 3, a sectionally changed portion is produced in the aperture between the mirror plate surface 10 and the lap end 11 and by a labyrinth effect in the portion, leakage due to the difference in gas pressure on the both sides of the lap 3 can be effectively reduced. Also, in case where oil is present in the aperture, the groove 14 serves to supply and hold oil, whereby an oil layer is always present between the mirror plate surface 10 and the lap end 11, making the sealing effect more completely. Also, in case where the mirror plate surface 10 is in contact with the lap end 11, the presence of the groove 14 increases greatly the strength of oil film, preventing the wearing between the mirror plate surface 10 and the lap end 11.

Abstract: PURPOSE:To form an extremely thin antistatic film having a film thickness of nanometer level on the substrate surface without impairing a function native to the substrate by introducing a electrically conductive group into a molecule of a chemical adsorption film using a chemical adsorption method. CONSTITUTION:For example, a hydroxy group of the surface of film substrate 21 is brought into constant with SiCl4 and the obtained product is hydrolyzed to provide a siloxane monomolecular film 23.

As the other method, this input audio signal is changed by removing the sequence of the sample corresponding to the pitch cycle from the input audio signal. Besides, synergy and velocity change operation for voice coding is performed. The filtering processing required for velocity change operation is performed by the linear predictive filter of voice coding.  The pitch cycle required for this velocity change operation is the known parameter of a voice decoding device.

Abstract: PURPOSE: To obtain the magnetic field detecting element with high sensitivity and broad dynamic range, by giving different width for at least one MR element from the direction flowing in it in the sense current, in the magnetic field detection element consisting of one of a plurality of MR elements formed on the substrate.  
     CONSTITUTION: The two strip shape MR elements 7, 8 having the same thickness and different widths W1, W2 are formed on the substrate 11 in the form of series connection together with the conductor terminals 9 and 10. They are connected to the current supply source 13 and the output terminal 14 via the conductor terminals 9 and 10. Further, W1 is greater than W2. The sensitivity of the MR element 7 W1 in width is greater than that of the MR element 8 W2 in width to the broadwise magnetic field HX. Accordingly, the MR element 8 is not saturated to the saturation magnetic field to the MR element 7. The MR elements like these can be plurally arranged in equal interval of 1/4 of the bit length. Thus, the dynamic range can be made broader with high sensitivity.
