Title: Steering force control device for power steering device
Inventor: NAKAMURA KYOICHI
IPC: B62D5/08
Filed: 1986-07-17
Abstract: PURPOSE:To maintain a steering force constant by controlling a reaction force chamber pressure approximately constant by suppressing a rise in a differential pressure by increasing the throtting area of an orifice when the differential pressure rises beyond a specified pressure due to increase in a pump rpm. CONSTITUTION:When a delivery flow rate Q increases due to a rise in a pump rpm, a differential pressure DELTAP(P-P1) between front and back of a fixed orifice 65 of an orifice 61 for detecting rpm increases. Accordingly, under a condition of a low vehicle speed, the pump rpm is low and the differential pressure is small and therefore a low differential pressure DELTAP produced between the fixed orifice 65 and a metering orifice 70 of a flow rate control valve 69 acts on a plunger 54. And when an input shaft is rotated by operating a steering wheel, the plunger 54 is readily pushed. This causes a sleeve valve member 32 and a rotary valve member 31 to produce relative rotation. When the vehicle speeds increase, DELTAP increases, a differential pressure introduced into reaction force chambers 55a and 55b increases, and the pressing force of the plunger 54 against a projection 50 increases.

Title: Double refractive diffraction grating type polarizer
Inventor: URINO YUTAKA
IPC: G02B5/30
Filed: 1989-06-28
Abstract: PURPOSE:To obtain the polarizer which allows the connection of diffraction gratings to >=3 stages and by which diffracted light is diffracted only in one direction by cascade-connecting the diffraction gratings having the refractive index distributions of a square waveform and setting the periods of the respective diffraction gratings at even times the respective periods. CONSTITUTION:The diffraction gratings 5 having the refractive index distribution of the square waveform are formed by subjecting a crystal substrate 1 consisting of lithium niobate, etc., having optical anisotropy to a periodic ion exchange or forming periodic plural grooves on the substrate or packing the anisotropic material into the grooves. The diffraction gratings of the square waveform do not generate the diffracted light of the even order exclusive of zero order if these diffraction gratings 5 are cascade-connected in three stages and, therefore, the offsetting of the diffraction angles of the diffracted light of the 1st order or above by each other and the formation of the zero order diffracted light (rectilinear light) as a whole are obviated in the case of the cascade connection of these diffraction gratings. The zero order diffracted light intensity over the entire part of the cascade-connected diffraction gratings, i.e. extinction ratio is the product of the zero order diffraction efficiency of the respective diffraction gratings and can be made sufficiently small when the number of steps is increased.
