Title: Apparatus for removing particulate in oil
Inventor: SAKANO KOUJI
IPC: F01M11/03
Filed: 1982-04-08
Abstract: PURPOSE:To certainly remove a particulate, by providing a charging aid supply part holding a charging aid generating charge to the particulate in engine oil between a cathode and an anode. CONSTITUTION:Engie oil enters an oil chamber 2 from an inflow port 15. At this time, a charging aid 6 stored in a charging aid supply part 5 passes the orifices of a partition wall 52 to be mixed in engine oil and applies charge to particulate contained in engine oil while the particulate is migrated to an anode 4 by the action of an electric field formed between a cathode 3 and an anode 4 to be adhered to and coagulated on the partition wall 52. After the part of the particulate is removed, the engine oil enters a top part 12 from the oil chamber to be retured to a diesel engine from an outflow port 16. In this case, as the charging aid, Ba or Ca sulfonate is used.

Title: Optical disk
Inventor: TSUCHIYA YOICHI
IPC: G11B7/259
Filed: 1987-03-13
Abstract: PURPOSE:To reduce a secular change of the reflectance of a reflecting film and to stably reproduced information over a long period by using a binary Al-Ti alloy or a ternary Al-Ti-Ag alloy to form the reflecting film on one side of a substrate. CONSTITUTION:One side of a substrate 1 has many pits 2, 2... corresponding to information to be recorded in a spiral line around the central axis. A reflecting film 3 of a binary Al-Ti alloy or a ternary Al-Ti-Ag alloy is formed on the substrate 1 so as to cover at least all the pits 2, 2.... The Ti in the film 3 inhibits the oxidation of the Al and suppresses the reduction of the reflectance of the film 3 due to oxidation. When the resulting optical disk is used, information can be stably reproduced over a long period without causing a bit error or nonreproducing.

IPC: G01M13/04
Filed: 1979-05-16
Abstract: PURPOSE: To detect the existence of a flaw, its size, etc., accurately by detecting the number of impulse responses by putting it to practical use that the detection signal of the acoustic sensor of a piezoelectric vibrator, etc., is the impulse response of vibration acceleration by the flaw.  
     CONSTITUTION: A piezoelectric signal detected by acoustic sensor 3 is input via amplifier 4 to band-pass filter 5, which removes random electric noises. Output SS of this detected signal, therefore, becomes a signal of a nearly-constant frequency and its envelope forms the impulse response waveform of an impulse wave generated due to a flaw, etc., of axis 1. Then, this detected signal is supplied to discriminator 6 to generate signal P every time it exceeds threshold level TL. Counter 8 counts pulse signal P for a predetermined unit time and the count value is displayed. Since the number of waves of this pulse signal P changes corresponding to the size of the flaw, the size of the flaw can accurately and easily be detedted from this number of waves.

Title: Manufacture of laminated body
Inventor: DEZUKI KIYOTO
IPC: B29C63/02
Filed: 1985-03-27
Abstract: PURPOSE:To efficiently manufacture a laminated body, which consists of fiber layer and thermoplastic resin layer and has water permeability or air permeability by a method wherein through holes are formed by the pressure difference produced by suction. CONSTITUTION:Resin layer 2 is supplied at nearly the same speed as the peripheral speed of a rotating cylinder 11 onto the surface of the cylinder 11 of a roll 10 for forming through holes in order to closely contact with the surface of the cylinder 11. When the resin layer 2 reaches a through hole forming range, to which a suction hood 15 is open, through the rotation of the cylinder 11, the resin layer 2 is pulled in through holes 12 due to the difference of pressures applied on both the sides of the resin layer 2 at the portion, which faces to the through hole 12, of the resin layer 2 and further developed and elongated until the bursting of the resin layer occurs at the bottom of a recess developed by the pulling on of the resin layer in the through hole 12, resulting in forming a through hole 8 in the resin layer. The pitch of through holes 8 and the diameter of the hole 8 formed on the resin layer 2 are determined in due consideration of the quantity of water flow or air flow in the environment, in which a laminated body 9 is used. The resin layer, in which the through hole 8 is formed, is successively pinched together with fiber layer 1 between the roll 10 for forming through holes and a pressure roll 20 in order to be manufactured into the laminated body 9.
