Title: Power steering device using variable displacement pump
Inventor: KATOU TOSHIYA
IPC: B62D5/07
Filed: 1994-03-28
Abstract: PURPOSE:To decrease a discharge flow rate of a variable displacement pump at the time of non-steering by providing a discharge flow rate control mechanism for decreasing the discharge flow rate of the variable displacement pump when the load pressure of a gear box is low during non-steering, and increasing the discharge flow rate of the variably displacement pump when the load pressure of the gear box becomes high during steering. CONSTITUTION:When the load presure applied to a gear box is below a fixed value like non-steering time, a load pressure sensitive valve 3 decreases the eccentricity amount of a variable displacement pump 1 in earlier timing as compared with that of steering time according to the load pressure. On the other hand, the power steering device is provided with a discharge flow rate control mechanism for increasing a discharge flow rate of the variable delivery pump 1 when the load pressure applied to the gear box becomes high during steering. Thus, during non-steering, the discharge flow rate of the variable displacement pump 1 can be lowered than that during steering so as to realize an energy-saving effect.

IPC: H05H13/04
Filed: 1991-04-15
Abstract: PURPOSE:To perform stable operation by providing a first and a second radiated light absorbing members opposing to each other around an accumulated electron beams, and mounting a pair of radiated light shields, inwardly extending in the radial direction, on both end parts in the circumferential direction of the first radiated light abosrbing member, further mounting cooling channels on the outside peripheries of both the absorbing member. CONSTITUTION:In an absorber 10, the radiated light radiated from an accumulated electron beams 4 is absorbed by a first radiated light absorbing member 1. The remaining radiated light, being unabsorbed and reflected by the member 1, is absorbed by a second radiated light absorbing member 2. A part of radiated light reflected by the member 1 causes diffused reflection. The advance of the diffused reflected light is limited only in the direction pointing the member 2 by the radiated light shield 3 of the member 1. Thus, since all of the radiated light reflected at the member 1 is absorbd by the member 2, the arrival of the radiated light to a beam duct 5 can be prevented. The heat caused at the members 1 and 2 are discharged from cooling channels 6.

Title: Reflection, refraction, reduction and projection optical system
Inventor: ICHIHARA YUTAKA

Filed: 1990-03-30
Abstract: PURPOSE:To clearly project a fine pattern with excellent resolution by providing a 1/4 wavelength plate between the polarizing beam splitter and the concave reflecting mirror of a reflecting system and a refracting system. CONSTITUTION:A first surface 10 where the pattern of an integrated circuit is formed and which corresponds to a reticle is irradiated with polarized light {(p) polarized light} from an illumination optical system. Luminous flux from the pattern on the first surface 10 is converted to almost collimated luminous flux by a first lens group G1 having positive refracting power and made incident on the polarizing beam splitter (BS) 11. The (p) polarized light transmitted through the BS11 is passed through the 1/4 wavelength plate 12 and converted to right (left)-handed circularly polarized light. Besides, it is made to diverge by a second lens group G2 having negative refractive power and made incident on the concave reflecting mirror 13. The luminous flux reflected on the mirror 13 becomes left (right)-handed circularly polarized light and it is passes through the lens group G2 and the wavelength plate 12 again while it is focused. Then, it becomes (s) polarized light. The luminous flux becoming the (s) polarized light is reflected on the BS11 and formed on a second surface 20 corresponding to a wafer surface by a third lens group G3 having the positive refracting power as the reduced image of a reticle pattern.
