Title: Reproducer
Inventor: KAMAI TOSHIMITSU
IPC: H04N5/93
Filed: 1982-09-28
Abstract: PURPOSE:To prevent the deterioration in a sound signal because of the generation of side band of a video signal, by detecting that a side band component of the video signal is generated in a channel of the sound signal, and extracting the signal of other channels in place of the signal of the channel having the side band component. CONSTITUTION:When the side band of the video signal takes place, the component at the outside of the sound band is extracted at HPFs 31L, 31R and detected at level discriminating circuits 32L, 32R. Since this sound distortion is generated only a channel and the other channels receive no effect, the abnormal sound due to the sound distortion is eliminated by replacing the signal from a signal of other channels. The switching is attained with the switch circuits 30L, 30R driven with the output of the discriminating circuits 32L, 32R. Thus, the sound signal is monaural during this switching, but no problem is arisen because of too short time.

Title: Thin film formation
Inventor: MITSUYA MUNEHISA
IPC: B01J19/00
Filed: 1993-07-09
Abstract: PURPOSE:To form a monomolecular film which is even at an atomic level and has a firm chemical linkage with a solid surface and mechanical stability by terminating interatomic linkages of the solid surface with fluorine atoms and then making the solid surface adsorb a desired compound. CONSTITUTION:After interatomic linkages of the surface of a solid are terminated with fluorine atoms, the surface of the solid is made to adsorb a desired compound. At that time, the fluorine-terminated solid specimen is immersed in either a non-polar solvent solution containing the desired compound or a liquid compound of the desired compound or is exposed to vapor of the desired compound. Otherwise, the surface of the solid may be terminated with fluorine by immersing the surface in an aqueous hydrogen fluoride solution with 0.1% or higher concentration. Moreover, the solid substrate is exposed to a rare gas fluoride in a vacuum and thus the surface of the solid may be terminated with fluorine. Meanwhile, the non-polar solvent may be saturated hydrocarbon or saturated fluorocarbon. The solid substrate is a crystal silicon. Consequently, a monomolecular film which is even at atomic level and has a firm chemical linkage is formed on the solid surface.

Title: Main bearing structure for crankshaft for internal combustion engine
Inventor: KOBAYASHI YOICHI
IPC: F16C9/02
Filed: 1994-07-22
Abstract: PURPOSE:To improve the flow of lubricating oil through a bearing part as worsening of the friction loss of a lower bearing metal of which a part of the main bearing of a crankshaft for an internal combustion engine consists is prevented from occurring. CONSTITUTION:The width of a lower bearing metal 3 is decreased to a value lower than that of an upper bearing metal 1. An oil groove 5 peripherally extending by a short distance and connected to an oil groove 2 formed in the inner peripheral surface of the upper bearing metal 1 is formed in the inner peripheral surface of the lower bearing metal 3 in the vicinity of the joint 4, positioned on the side where rotation from the upper bearing metal 1 toward the lower bearing metal 3 is effected, of a joint between the upper and lower bearing metals 1 and 3. Thus, the lower bearing metal 3 has width enough to hold an oil film and support a crank shaft and a proper slide area, whereby incurring of a friction loss is reduced. Since the oil groove 5 has a function to introduce lubricating oil to the lower bearing metal 3 side, a possibility for an amount fed to the lower being metal 3 to reduce is eliminated and lubrication of the lower bearing metal 3 is improved.
