Title: Optical recording medium
Inventor: ISHITOBI YOSHIMITSU
IPC: G11B7/24033
Filed: 1982-06-28
Abstract: PURPOSE:To reduce laser light power required and contrive to enhance preservability and recording speed, by a method wherein a laminate layer or a mixed layer of a photoconductor and a recording material is provided, and information is written by jointly using electric discharge energy and thermal energy of laser light. CONSTITUTION:An electrically conductive layer 2 is provided on a base 1 such as polyester or the like by aluminum vapor deposition or the like, then a photoconductive layer 3 and a recording layer 4 are laminated thereon, and a transparent electrically conductive layer 5 is provided thereon by applying indium oxide or the like. The photoconductive layer 3 has internal impedance lowered when being irradiated with light, and is constituted of, for example, a mterial obtained by mixing zince oxid into a resin. The recording layer 4 is so formed that a hole is opened by electric discharge phenomenon of a local electric current, and is formed of, for example, a light-transmitting polyester. When a DC voltage is impressed on the conductive layers 2, 5 of the thus formed optic recording medium (a) and laser light 6 is projected to a desired part P1 from above, the impedance of the photoconductive layer 3 is locally lowered, and the voltage is impressed concentrically on a point P3, thereby forming a bit in the recording layer 4.

Title: Method and device for inspecting surface by retro-reflection screen
Inventor: MORI YOSHIICHI
IPC: G01B11/30
Filed: 1991-05-16
Abstract: PURPOSE:To enable a capability for detecting a pseudo image at a defective portion to be improved by allowing a luminous position of a light source to be moved to a plurality of locations and an image which is captured by a camera to be subjected to addition by an image-processing device for each movement of the luminous position. CONSTITUTION:Light sources 3a, 3b,... and 3n are placed at relative positions where light of the light sources hits against an object 5 to be inspected, is reflected, and then travels toward a retro-reflection screen 1. The light sources 3a-3n are successively lit up by a light source switcher 6, one light at a time. A timing of lighting is synchronized to a timing signal generator 12 and a timing signal simultaneously allows an image pickup timing of a camera 2 to be synchronized. When the light source 3a-3n are lit successively, the luminous positions are moved. Therefore, an image which is captured by the camera 2 for each luminescence of light sources 3a-3n is subjected to addition by an image processing device 8 and a traveling pseudo image becomes ambiguous when it is observed by a monitor 9. However. since the defective image is fixed, the image is highlighted, thus preventing the pseudo image from being regarded as the defective portion by mistake.

Title: Parity generation detecting circuit
Inventor: KANETSUNA HIROSHI
IPC: G06F11/10
Filed: 1985-05-27
Abstract: PURPOSE:To cope with high-speed operation by adding a circuit which holds temporarily the detection information and a circuit which switches the information between said information holding circuit and a CPU, to a memory that is unable to cope with the high-speed operations and a parity generation detector. CONSTITUTION:In a write mode data are written to a memory 8 according to the address information and a write instruction produced from a CPU 7. At the same time, the data are led to a parity generation detector 13 via a selector 14 and turned into the write parity information. This parity information is written to a parity memory 9 via a gate 12. In a data read mode both memories 8 and 9 produce the information according to the address information and a read instruction produced from the CPU 7 and hold these information in registers 10 and 11. In the read mode the selector 14 and a gate 15 lead the contents of registers 10 an 11 to a parity generation detector 13. The parity detection is performed in a normal way even though the response time of the detector 13 is slower than the read instruction. Thus the check result can be held in a register 16.
