Title: Memory device for temporary storage of charge
Inventor: KUROKI YUKINORI
IPC: H01L27/108
Filed: 1983-09-12
Abstract: PURPOSE:To obtain the unit cell of the DRAM suitable for increasing the density and the capacitance by a method wherein the side and the bottom of a groove dug in the Si substrate surface are made of a high concentration impurity layer of the same conductivity as that of the substrate or a metal or an alloy in ohmic contact with the substrate. CONSTITUTION:An N<+> drain 301 a switching element, a P<+> channel stopper 302, and a field oxide film 304 are provided on the P type single crystal Si substrate 300, and a P<+> layer 303, an oxide film 305, and the upper electrode 306 on the side and the bottom of the groove deeply dug in. In this construction, even when electron-hole pairs generate by the passage of alpha rays, the Si surface at the capacitor part is kept neutral by recombination without generating the gradient of potential in the presence of the P<+> layer; accordingly information is not disturbed, and the surface potential does not vary. Since a depletion layer is not formed in the surface, the gap between adjacent capacitors can be made fine in dimension, and the groove can be utilized for isolating the adjacent cell from the switching element. Thus, the unit cell of the DRAM suitable for increasing the density and the capacitance can be obtained. Besides, the capacitor electrode on the substrate side can be also made of a metal or an alloy in ohmic contact.

Title: Tire with tube, and tubeless tire
Inventor: YAMAGIWA TOSHIO
IPC: B60C5/00
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To make a vehicle continuously travel when a flat tire is generated, and to prevent deterioration of the performance even after the tire is used for a long time. SOLUTION: A large number of rubber or foamed urethane spherical bodies 16 are filled in an air chamber 3 in a tube 2 of a tire T with tube, or an air chamber of a tubeless tire, and the volume (the total volume) of the spherical bodies 16 is 50-80% of the volume of the tube 2 in an inflated condition. When the tube is pierced by a nail, etc., and air is leaked from the air chamber 3 of the tube 2, i.e., in a flat tire condition, the external shape of the tire 1 is kept in a certain degree because a large number of spherical bodies 16 are present in the space of the air chamber 3 below the compressed tube 2, and a vehicle can continuously travel for a short distance to e.g. a repair shop. Because no load is applied to the spherical bodies 16 themselves during the normal traveling, the bodies are not reduced in volume or hardened by the load, and can be used for a long time.

Title: Manufacture of moved plate member of clutch
Inventor: HARA YASUHIRO
IPC: F16D13/62
Filed: 1991-07-09
Abstract: PURPOSE:To make flat the moved plate member of a clutch and stabilize motion of the moved plate member by constructing the clutch in a double structure from a backup member of light alloy and a friction material, making the roller on the backup member side with a dia. greater than that of the roller on the friction disc side, permitting to pass between the two rollers, and thereby eliminating possible warp of the moved plate member of the clutch. CONSTITUTION:The moved plate member 1 of a clutch is embodied in a ring form, and a friction material 3 is placed on a backup member 2 made of Al allow and they are heat shaped as in a single piece, through which a bending moment is given, and they undergo plastic deformation. Thus the intended shape is achieved. The warp produced at the time of heat shaping is corrected by passing the material between a plurality of roller couples 4, 5, upper and lower. Therein the backup member 2 is deformed plastically while the friction material 3 is formed elastically, and therefore, the backup member 2 must be deformed effectively. Therefore, the dia. of the roller 5 on the backup member 2 side shall be formed greater by an amount corresponding to the thickness of the friction material 3 than the dia. of the roller 4 on the friction material 3 side. This eliminates possible warp of the moved plate member 1 of the clutch to achieve its flatness, nullifies dislocation of rivet boring, and enables uniform polishing. Thus a stable moved plate member 1 can be fabricated.

Title: Formation of magnetic tape
Inventor: TAKAHASHI KIYOSHI
IPC: G11B5/84
Filed: 1980-11-28
Abstract: PURPOSE:To obtain a magnetic tape which is free of creases and curvature and never varies in electromagnetic conversion characteristics, by forming a magnetic metallic thin film of the surface of a plastic film and by winding the tape while slitting both its widthwise end parts to specific width after pressing the tape in contact with a heat roller with constant tensile force. CONSTITUTION:On a plastic film surface 21, a magnetic metallic film 22 is vapor-deposited. In this case, creases 23 are generated at the boundary between an nonmetallic part and the metallic film. If the film is wound as it is, the attitude of winding is disordered and when it is sized long, creases 23' are generated at the center part. To prevent those, the film after the vapor deposition is pressed against <=1 heat roll, thus eliminating the creases, curvature, etc. Then, both the end parts are slit to 5-30mm. width including the unnonmetallic part 21 and a metallic part to wind the film. The variations of electromagnetic conversion characteristics of a magnetic tape obtained as mentioned above are reduced. Thus, the quality and yield of the magnetic tape are improved.

Title: Sheet feed device
Inventor: KIMURA ATSUSHI
IPC: B65G27/24
Filed: 1989-06-30
Abstract: PURPOSE:To improve sheet holding force during transfer stopping, in a vibration type sheet feed device used for a computer or the like, by forming a circular oscillating body provided with a pair of straight parts pressing a sheet along a sheet transfer direction, providing plural number of slits only in a sheet pressure surface at either of straight parts, and forming comb toothed oscillating pieces. CONSTITUTION:When a sheet is pressed against an oscillating body 2 to generate an out-of-plane bent traveling wave, the transfer force of which the traveling wave as usual is opposite to the traveling direction works at the left straight part. On the other hand, when pressure is small at the right straight part, air layer is formed between the sheet and the oscillating body 2 because there is not an air outlet like a slit S, a traveling wave in a traveling direction is generated because of squeeze effect, so that transfer occurs. Under no existence of a traveling wave, the sheet is supported by pressure at both the ends.
