Title: Optical member inspection device
Inventor: KIDA ATSUSHI
IPC: G01N21/958
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To provide an inspection device for outputting data for indicating such causes of failure as the birefringence state of an entire optical member, refraction force failure, and dust/dirt. SOLUTION: White light emitted from a light guide cable 1 is diffused by a diffusion plate 2 where a knife edge 2a is formed and enters a lighting side polarization filter 3. The lighting side polarization filter 3 transmits only linear polarization light in a certain direction and the light is applied to an optical member A. The vibration direction of the linear polarization light through a part causing birefringence within the optical member A is rotated. A camera side polarization filter 4 transmits only the linear polarization that vibrates in the same direction as the linear polarization transmitted by the lighting side polarization filter 3. Therefore, the quantity of light through the part for causing birefringence within the optical member is attenuated.  On the other hand, when refraction failure occurs, the state of the image of the knife edge 2a being picked up by an image pick-up device 5 is disturbed.

IPC: H04B1/03
Filed: 1992-07-09
Abstract: PURPOSE:To prevent the remodeling action because an electronic equipment can not be subsequently used by exchanging the part of the data of a memory for dummy data other than the dada required by a CPU by the CPU when a case is opened. CONSTITUTION:Electric power is supplied from a preliminary power source 11 for remodeling prevention to a memory 20 via a subswitch S2 and a diode D2.

When a case is opened, electric power is supplied to the CPU 10 from the route which is different from a main power source 1 since a switch S2 is actuated. Thus, a rewriting means 10p incorporated as a program in the CPU 10 is actuated, dummy data is written in the memory 20, the contents is rewritten and an electronic equipment is made not to operate normally. As a result, the opening of the case for the purpose of a remodeling is prevented.

Filed: 1995-07-20
Abstract: PROBLEM TO BE SOLVED: To prevent the dielectric breakdown of a switching element and a wiring intersection part by connecting at least one of plural gate wires and data wires by short-circuit wires. SOLUTION: On one surface 22a of an insulating substrate 22, a looped gate short-circuit wire 24 and plural data short-circuit wires 25-27 are formed at mutual intervals while surrounding all the gate wires G and data wires D.
