IPC: G02F1/01
Filed: 1988-11-16
Abstract: PURPOSE:To vary a phase difference freely by applying various stress to a material which shows optoelastic effect as the phase plate. CONSTITUTION:The optoelastic effect member 2 formed shaping the material which provides the optoelastic effect in a shape of a rectangular prism is mounted on a support base 3 made of metal, etc., in a U-sectioned shape and a pressing means 4 which applies stress to the optoelastic effect member 2 at right angles to the transmission direction of light is provided to the support base 3. Then the pressing means 4 applies stress with a screw 7 while a pressure plate 6 is arranged on the flank of the optoelastic effect member 2. Namely, when the light 5 is transmitted through a phase plate 1 and the pressing means 4 applies the stress to the optoelastic effect member 2, birefringence is caused in the optoelastic effect member 2 of glass, etc., by the optoelastic effect to generate a difference in refractive index between the X-axial and Y-axial directions of the optoelastic effect member 2. Consequently, the phase difference is varied freely.

IPC: G06F11/22
Filed: 1992-10-03
Abstract: PURPOSE:To shorten prescribed time for memory check by enabling a read/write test on plural memory banks to be performed simultaneously by comprising a system so that output data in each memory bank can arrive at a comparator, but it cannot arrive at a data bus when the memory bank is read out. CONSTITUTION:Disconnection circuits are inserted between data input terminals and a data bus, respectively. When the read/write test is performed, prescribed data is written on all the addresses of the memory banks #1-#n, and after that, the data bus is disconnected from the data input/output terminal by the disconnection circuit. Thence, data in the memory banks #1-#n are read out by read/ write control, and they are supplied to the comparator. The comparator compares the data in the memory banks #1-#n, and outputs an error signal when noncoincidence is obtained. The output of the data H to the data bus is prohibited by the disconnection circuit to prevent the collision of the data read out from all the memory banks #1-#n on the data bus at that time from occurring.
