Title: Magnetic disk and magnetic recording and reproducing method using the same
Inventor: HONDA NAOKI
IPC: G11B5/73
Filed: 1989-05-19
Abstract: PURPOSE:To prevent a crack from being generated on a metal magnetic thin film by specifying the penetration stiffness of a magnetic sheet in correspondence to the thickness of a non-magnetic supporting body and the difference of a radius for the fixed part of the magnetic sheet. CONSTITUTION:Magnetic sheets 3 and 4 provided with flexibility, are fixed to the outer peripheral part and inner peripheral part on both sides of a discoid rigid substrate 2 by an adhesive, etc., with the prescribed penetration stiffness. When the thickness of the non-magnetic supporting body is defined as 8mum and the radius difference of the fixed part in the magnetic sheets 3 and 4 is defined as  r mm, the magnetic sheets 3 and 4 are stuck so that the penetration stiffness can be less than 90.8/ r mg/mum. This value of the penetration stiffness is an upper limit value so that the crack is not generated on the metal magnetic thin film to be formed on the non-magnetic supporting body when the magnetic sheets 3 and 4 are spread over the rigid substrate 2. Thus, a magnetic disk 1 equipped with the metal magnetic thin film, where the crack is not generated, can be obtained.

Abstract: PURPOSE:To obtain the water drop sounding jar which is small-sized, easily installed without being buried in the ground, and placed at hand by forming the respective parts of a water basin, the respective parts of a main body jar, and a receiving pan. CONSTITUTION:A water basin center hole 3 is bored 5 in the center of the water basin 1 to drip water, and drops of water falls in the main body jar 7. A sound quality adjusting body 15 is placed on the water basin center hole 3 or the water drop hole 5' of the upper part of the main body jar. A water drop spread open groove 6 is arranged in a proper circular shape in the center of the reverse surface of th slanting surface 5 of the upper part of the main body jar 7. The bottom of the main body jar 7 is extended and the lower terminal 7' of the main body jar is placed on the receiving pan 8. Thus, this sounding pot is constituted as a desk-top type which can be easily placed in any of a Western-style room, a Japanese room, an entrance, and a corridor, and drops of water are fallen in the jar 7 whose internal space is made large. When a drop of water falls and strikes on the water surface of water at the bottom part of the jar 7, a sound is generated and reverberated in the internal space of the jar 7, thereby a unique water drop sound.

Title: Opposite polarity plasma welding method
Inventor: UKAI JIYUN
IPC: B23K9/00
Filed: 1978-10-12
Abstract: PURPOSE: To prevent the arc break of plasma arc and enable a large amount of deposition to be obtained by heating a welding rod and letting the same arrive at the arc part.  
     CONSTITUTION: The welding rod 5 fed by feed rollers 5 is fed within an opposite- polarity plasma arc 3 in the state where it is heated or partly melted by the arc 8 generated from a TIG welding torch 6. Then, it achieves perfect melting with a slight plasma heat source and melts in the peripheral part of the plasma arc 3. The molten state is freely controlled by increasing or decreasing the current of the TIG welding arc 8. Since this prevents the unmolten welding rod 5 from entering the central part of the plasma arc 3, the cathode point of the plasma arc 3 is formed on the built-up metal and shifting of the cathode point to the welding rod 5 is obviated. Hence, the plasma arc 3 may be reached to the front of the material 2 to be welded.

     CONSTITUTION: An electric conductive reinforcing plate 14, a post-shaped electrode 15, and a radiator 16 are placed in this order on a primary plane of a semiconductor pellet consisting of a primary and a secondary thyristors 11, 12. Grooves 21 are provided to the plate 14 and the electrode 15 to divide them to form regions A, B which correspond to the primary and secondary thyristors. By so doing, majority of the regions A, B are separated although some areas are connected at 14 3 , 15 3 . Thus low temperature is maintained at the junction of the secondary thyristor 12 even if the primary thyristor is heated due to a temperature increase by receiving light for a phototrigger and due to electric conduction after being triggered. Thereby, withstand voltage drop and dV/dt misignition can be prevented.

Abstract: PURPOSE: To obtain an automatic sampling apparatus by which experience technique, labor and time, are saved and by which a sampling operation representing an object resin as a whole can be performed by sampling the resin which is fed so as to flow in a transfer pipe one part by one part automatically and intermittently. CONSTITUTION: By a resin flow and feed starting signal from a flow and feed detection sensor 13, a control means 16 opens and shuts an electrically-driven valve 14 intermittently. Then, a part of a mixed resin which is moved in a transfer pipe 16 flows into a metering tank 12 via a sampling pipe 11 whenever the valve 14 is opened. When a constant amount is stored in the metering tank 12, a resin-amount detection sensor 15 shuts the valve 14, and a sampling operation is finished. Then, a valve 19 at a resin discharge pipe 18 is opened, the resin is sent to an automatic resin ion composition measuring device 20, and its performance is measured and evaluated.  In this case, the intermittent time for opening and shutting the valve and the time for keeping the valve open are adjusted in such a way that a prescribed amount is sampled so as to average the mixed resin which is being sent flowing to a demineralizing column. Thereby, a sampling operation respresenting the whole mixed resin as an object to be sampled, which is fed so as to flow can be performed automatically.

Abstract: The invention relates to a new process for etherifying at least one phenolic functional group of mono- or of polyphenols. It consists essentially of the reaction of a phenolic compound with an etherifying agent chosen from the group consisting of saturated aliphatic alcohols containing 1 to 6 carbon atoms or unsaturated ones containing 3 to 6 carbon atoms, the said process being characterised in that it is carried out in the presence of a carboxylic acid salt. The arylaliphatic ethers obtained may be either employed directly, for example in the pharmaceutical industry, or as intermediates for the synthesis of more complex compounds.
