Title: Optical system including diffraction optical element
Inventor: ISHII TETSUYA
IPC: G02B5/18
Filed: 1995-05-09
Abstract: PURPOSE: To prevent the occurrence of flares and ghosts by light of the unnecessary order by providing the exit side of a diffraction optical element with a diffraction selection element which allows the transmission of the diffracted light of prescribed order and attenuates the diffracted light of the other order. CONSTITUTION: This imaging optical system 70 has a refractive lens 71 having positive refracting power and a diffractive lens 72 having positive refracting power. The diffractive lens 72 is brazed in such a manner that its first order diffraction efficiency is maximized at the wavelength near the middle of the wavelength band to be used. An image pickup element 60 is arranged in the imaging position of the imaging optical system 70. The diffracted light selection element for allowing the selective transmission of the diffracted light of a prescribed order and attenuating the diffracted light exclusive of the order, for example, an NA limiting member (louver) 30 which limits the luminous flux having the numerical aperture larger than the numerical aperture of a prescribed size, is arranged on the exit side of the diffractive lens 72.  As a result, the degradation in the performance of the optical system according to the dependency of the diffraction efficiency on wavelengths in the case the plural wavelengths or band light regions are used is lessened and the occurrence of the flares and ghosts by the light of the unnecessary order is prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent a braking distance from being increased in the situation that a vehicle should be urgently stopped by prohibiting the decrease of the braking force by a stop shock mitigating/regulating means when an obstacle is detected within the prescribed distance in the front of the vehicle. SOLUTION: The distance to an obstacle in the front of a vehicle is detected by an obstacle detecting unit 70. When an electronic control unit(ECU) 30 detects that the obstacle exists within the prescribed distance in the front of the vehicle based on the detection signal from the obstacle detecting unit 70, it turns on holding solenoids 38, 40 (to close valves) and turns on decompression solenoids 60, 62 (to open valves), it cuts off wheel cylinders 42, 44 from a master cylinder 20, and it communicates them with a reservoir 54. The brake fluid in the wheel cylinders 42, 44 flows out to the brake reservoir 54, and the wheel cylinder pressure is decreased to mitigate the braking force.

Filed: 1988-05-09
Abstract: PURPOSE:To always make the supply mounts of wire members equal to each other by arranging a feed roller and a length measuring roller in such a way that their imaginary axes swing around an electric wire supply line. CONSTITUTION:Even though the diametrical dimensions of electric wires 10a, 10b are different from each other, when first and second opening and closing arms 26a, 26b are closed, a first conveying roller 27a is inclined around an electric wire supply line so as to absorb the difference in diametrical dimension between the electric wires, and accordingly, first and second toothed endless belts 10a, 10b make close contact with both electric wires 10a, 10b. Accordingly, upon supply of the electric wires, they are fed by amounts proportional to the rotating amounts of the first and second belts 29a, 29b without they slipping on the first and second belts 29a, 29b so as to make the feed amounts of the wires 10a, 10b equal to each other. In this arrangement, a first length measuring roller 28a is also inclined so as to be parallel with the first supply roller 27a, thereby it is possible to prevent the second belt 29a from being twisted and to make the tensions thereof uniform in its entirety.

Title: Semiconductor memory device
Inventor: HARADA HIROSHI
IPC: H01L29/792
Filed: 1983-06-22
Abstract: PURPOSE:To reduce the variation of the substrate potential at the time of hole injection by the reduction of the substrate resistance while the specific resistance of the region for electrode formation is set high by a method wherein a single crystal layer of the same conductivity type as that of a semiconductor substrate and a higher specific resistance is formed on the substrate having a lower specific resistance, and then a memory cell array is formed on this single crystal layer. CONSTITUTION:The single crystal layer 20 having a higher specific resistance (e.g. 20OMEGAcm), approx. 30mum thickness, and the same conductivity type as that of the semiconductor substrate 11' is formed on the substrate 11' of a lower specific resistance (e.g. 0.2OMEGAcm) by a vapor growing method, and the element (memory cell array) is formed on this layer 20. In such a construction, a substrate current I due to holes generating at the time of write to a transistor Tr1 is 2-3mA; however, the specific resistance of the bulk 10 is small and the increase of the specific resistance of the bulk 10 is small and the increase of the substrate potential is small. Therefore, the potential can be stabilized, and the variation of the threshold voltage of a parasitic transistor Tr2 is reduced, resulting in little decrease of the amount of written information. Thereby, the supplied current to the transistor Tr1 can be increased, and accordingly the time for write can be shortened.
