Title: 4-valve, 4-cam engine
Inventor: YAMAMOTO YOSHITAKE
IPC: F02F1/24
Filed: 1998-06-08
Abstract: PROBLEM TO BE SOLVED: To enable valves to withstand two times the current number of revolutions per minute by providing a specified number of valves on both the intake side and exhaust side of a reciprocating engine and by operating each of these valves of both the intake side and the exhaust valve alternately. SOLUTION: The present invention enables higher revolutions in a four-valve engine, which has two intake valves and two exhaust valves per one cylinder most commonly found in a reciprocating engine, by changing the way the valves are operated. In a four-valve engine having two intake valves and two exhaust valves, one intake valve is used during intake and the other intake valve rests. During the next intake, the intake valve which was resting is used and the valve that was used rests. If the exhaust valves are also operated in this same manner, the valves are only worked half as much as they were in the past. Put simply, the valves are able to withstand twice the number of revolutions per minute as they were in the past.

Title: Base film for magnetic card
Inventor: MOGI MASAHIKO
IPC: G11B5/80
Filed: 1987-08-21
Abstract: PURPOSE:To prevent the generation of an erroneous optical signal due to surface scratch and to enable clear printing by laminating polyester films A contg. >=0.5wt.% titanium dioxide on both sides of a polyester film B contg. carbon black. CONSTITUTION:Polyester films A contg. >=0.5wt.% titanium dioxide are laminated on both sides of a polyester film B contg. carbon black by such an amt. that the transmissivity of the film is reduced to <=50%, preferably <=1% when the wavelength of rays of light from a light source is 9,000Angstrom . The films A are films stretched in at least one direction, preferably biaxially stretched films. When the resulting base film is used, no erroneous signal is given to an optical signal detecting part even though a magnetic layer or a coated layer of a light shielding material is peeled or scratched by repeated use. Since the surface layers are white because of the titanium dioxide, a clear printed card can be formed by one-side or both-side printing.

IPC: H04N1/107
Filed: 1986-09-03
Abstract: PURPOSE:To reduce or prevent miscellanious light due to reflection on the inner or lower surface of platen glass and to obtain an excellent white and black picture with a good contrast and an excellent color picture with a good color balance by providing parallel light shielding members with gaps in parallel with the platen glass in front and behind in the moving direction on the upper side of a housing for a light source. CONSTITUTION:Since a light emitting material 50a applied to the tube wall of an aperture type fluorescent tube 50 is mixed with a material to improve reflectance, a large amount of the quantity of emitting light comes out from an opening part 50b, and less light leaks from the tube wall. As the leakage light from the tube wall and light reflected by the platen glass 1 enter into a solid-state image pickup element as unnecessary light to affect said element adversely, the four corners of a pair of fluorescent tubes 50 are surrounded by a housing 41. Anti-reflection black treatment is applied to the inner and outer surfaces of the housing 41. The upper surface has an opening 41a required for projecting light coming out of the opening part 50b of the fluorescent tube 50 on an original, while the lower surface of the housing 41 has a thin slit-like opening 41b required for driving the optical image of the original 2 to an optical system. The width dimension of the direction in which the light shielding member 42 moves becomes more effective as it is longer. However more than twice the gap dimension between the platen glass 1 and the lower surface 1b is preferable, if possible more than five time is preferable.
