Title: Identification cable
Inventor: NISHI SHIRO
IPC: G09F3/20
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide an identification cable which always retains a clean surface without sludge materials adhering thereon. SOLUTION: An identification cable 1 is an cable on whose surface an identification mark 4 for identifying a cable sort is formed, wherein a forming material of the identification mark 4 contains a metal oxide having a photocatalyst function. Since the identification mark 4 which contains the metal oxide layer having the photocatalyst function on the surface of the metal oxide layer, the surface of the identification mark becomes super hydrophilic through the activation effect of a metal oxide die to high-energy rays such as ultraviolet rays, consequently, even when water containing a sludge material splashes the cable 1, the water disperses over the entire surface of the identification mark 4 without agglutinating to make a polka-dot pattern, thereby after the water evaporates, the surface of the identification mark 4 always shows a clean surface,  so that the cable sort can be identified clearly.

Title: Torsion bar type rear sxle device
Inventor: HATA HIDEYUKI
IPC: F16F15/10
Filed: 1978-03-24
Abstract: PURPOSE: To effectively prevent wind-up noises in conditions where transmission torque is small by forming a rear axle of inner and outer drive shafts and making one of the shafts idle according to the torque.  
     CONSTITUTION: In such smaller average torque range as in third or fourth speed, tooth rows 11a idle in impact fit grooves 10b so that torque is transmitted only by an inner shaft 1 and a vibration occurs in a smaller spring constant rage. In such larger average torque range as first or second speed, torsion of the inner shaft 1 causes the tooth rows 11a to impact fit the ends of the grooves 10b so that torque is transmitted by inner and outer shafts 1 and 2 and a rear axle attains increased torsion rigidity. Because the axle 3 attains two-step variable torsion rigidity according to the torque strength, vibration transmission rate in third or fourth speed is decreased and wind-up phenomenon is effectively prevented.
