Title: Valve lift varying mechanism for internal combustion engine
Inventor: TAKIZAWA MASAAKI
IPC: F01L1/12
Filed: 1978-03-14
Abstract: PURPOSE: To raise the natural frequency of a valve lift varying mechanism employing a hydraulic tappet and prevent noises, by providing in an oil pressure chamber a spring for applying a force to a check valve to reduce the volume of a pressure chamber.  
     CONSTITUTION: The vibration of a spring system is generally represented as f= {(K 1 +K 2 ).g/w} 1/2 /2π where K 1  and K 2  denote spring constants. Therefore, f is increased by raising K 2  if K 1  and w are constant. The check valve 57 having a conical face is thrusted upward by the tension spring 59 provided in the oil chamber 53b so that the conical face is fitted on a valve seat. Because the spring 59 is placed in the oil chamber 53b, the volume of the pressure chamber 51b is thoroughly reduced. Thus, the natural frequency of the vibration system including the hydraulic tappet and an intake valve is increased and noises are prevented.

Abstract: PURPOSE:To obtain an impact head apparatus with limited power consumption and noise by a simple and inexpensive means by providing a silencing member made up of magnetic material and elastic material at least a part of a magnetic path containing a fixed core and a mobile core. CONSTITUTION:A silencing member 9 is fastened on the top surface of each fixed core 8. The silencing member 9 is made up of magnetic materialand elastic material and formed in the shaped of a flat disc to almost match the top surface of the fixed core 8. When the energization of a coil 10 is released, a mobile core 3 abuts against the silencing member 9 as attracted in the direction of the arrow A and attracted to the fixed core 8 through the silencing member 9, so that any contact impact can be absorbed by the damping action of the silencing member 9 to eliminate the generation of a large contact sound. During the attraction to the core, a gap is caused between the mobile core 3 and the fixed core 8 because of the interposition of the silencing member 9. But the silencing member 9 deforms and gets tight on both cores to accommodate the shape and inclination of the bottom of the mobile core 3 to hardly produce a clearance therebetween thereby minimizing the permeance loss of the magnetic path.

Filed: 1980-03-11
Abstract: PURPOSE: To prepare gas barrier and transparent plastic film by a method wherein fine powders of polyvinylidene chloride resin are added to latex and then coated on the plastic film.  
     CONSTITUTION: There is no specified method of preparation for fine powders of polyvinylidene chloride resin (PVDC) and it is desired for the resin to be pulverized to the microne size. When the diameter of a particle is excessively large, the gas barrier effect becomes small and additives are sbliged to be increased. The PVDC used as a coating agent in this invention is limited to aqueous base one. Fine powders of this PVDC are added to latex and coated on the plastic film. Surface treatment and anchor coating are conducted on the plastic film of this invention, if necessary. Thus, the film of this invention is entirely equivalent in the effect to the film treated by the conventional gas barrier agent and rather more excellent in transparency.

Abstract: PURPOSE:To attain the tracking with high accuracy and a large allowable eccentric degree by detecting the position of an optical pickup unit via an electromagnet and an electromagnetic position sensor and at the same time shifting the pickup unit until it is adsorbed by the electromagnet by a linear motor. CONSTITUTION:A carriage 10 contains an electromagnet 17 forming an oscillating motion holding mechanism and a electromagnetic position sensor 24 set opposite to each other centering on an optical pickup unit PU15. The position of the PU15, i.e., the gap between a magnetic plate 15b and the electromagnet 17 is detected by the electromagnet 17 and the sensor 24. At the same time, the PU15 is shifted by a linear motor 11 until the PU15 is adsorbed by the electromagnet 17. The driving of the motor 11 is controlled so that the moving speed of the arm 15 is lowered as the gap is gradually reduced. Thus the PU15 has a slow collision against the electromagnet 17, and the PU15 is adsorbed and held simultaneously with collision. Thus it is possible to attain the tracking with high accuracy and a large allowable eccentric degree.
