Patent JP-S6040711-A (JP)
Title: Valve mechanism
Inventor: TAKESHITA YOSHIHIRO
IPC: F01L9/10
Filed: 1983-08-12
Abstract: PURPOSE:To generate large force at the start of opening an exhaust valve to securely start the opening of said exhaust valve, by forming larger diameter and smaller diameter chambers in a cylinder chamber and also forming the corresponding piston into one having larger and smaller diameters, in a hydraulic cylinder device which opens and closes said exhaust valve. CONSTITUTION:When a first solenoid valve 21 is opened by means of a control device 20, hydraulic pressure enters a larger-diameter chamber 6 through a first oil passage 11, and a piston 8 is advanced by means of force acting on a larger diameter part 9. Thereby, an exhaust valve 3 starts to open its exhaust port 2, while the larger diameter part 9 closes a fourth oil passage 14. Because of the large diameter of the larger diameter part 9, the exhaust valve 3 can be securely opened with a less hydraulic pressure. When the piston 8 is further advanced, a third oil passage 13 connects the larger diameter chamber 6 of a cylinder chamber 5 with its smaller diameter chamber 7, causing hydraulic pressure in the larger diameter chamber 6 to enter the smaller diameter chamber 7, and the piston 8 is, then, advanced by means of force acting on a smaller diameter part 10. On the other hand, when the first solenoid valve 21 is closed and a second solenoid valve 22 is opened, the piston 8 is moved backward.

Title: Optical scanner
Inventor: MOCHIZUKI KENJI
IPC: B41J2/44
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To reduce spherical aberration without providing a correction lens and the like separately so as to cope with the high dot density of a recording medium by allowing a luminous flux made nearly parallel by a collimator lens to have an excessively corrected spherical aberration. SOLUTION: A luminous flux emitted from a light source 41 is collimated by a collimator lens 42, deflected by a light deflecting means 43 and formed into an image on a medium to be scanned 45 by a scanning lens 44. In this case, the surface of the lens 42 is a high-order aspherical surface, so that the converging action is smaller at a part away from the optical axis than a part near the optical axis. Therefore, a light beam 47 near the optical axis advances nearly in parallel with the optical axis 46 and a light beam 48 whose incident height is large advances diverging with respect to the optical axis 46. Namely, the spherical aberration of the lens 42 is excessively corrected.  Meanwhile, the spherical aberration that is insufficiently corrected is caused in the lens 44 because the lens 44 has a large NA, and they are cancelled each other, so that the spherical aberration of the entire device is almost zero.
