Title: Optical information recording medium and information reading method
Inventor: TAKEUCHI SATOSHI
IPC: G11B7/24085
Filed: 1986-12-05
Abstract: PURPOSE:To omit a track exclusive for follow-up and to improve the information recording density by forming a diffraction grating on each track surface and discriminating a relevant track to its adjacent tracks based on the difference of diffraction characteristics. CONSTITUTION:A recording tracks include the tracks 4 (4a, 4b) of a first attribute and the tracks 5 (5a, 5b) of a second attribute. Then a diffraction grating is formed with a diffraction constant (d) to each track 4 in the direction of +45 deg. to the track forming direction and also to each track 5 in the direction of -45 deg. to the track forming direction respectively. As a result, the different diffraction characteristics are secured between those tracks 4 and 5. Thus the diffracted beams have different emitting directions. Therefore all tracks can be used as recording tracks and the information pits are formed on all tracks. As a result, the information recording density is improved.

Title: Sucking device for plate glass
Inventor: NAGASAWA IKUO
IPC: B65G49/06
Filed: 1994-11-25
Abstract: PURPOSE: To block the occurrence of breakage to a plate glass by preventing thrust of an elevating cylinder from being transmitted to the plate glass through a sucking pad. CONSTITUTION: A support member 14 vertically movably supports a sucking pad 16 through a shaft 20 and the sucking pad 16 is supported in a suspending state through a shaft 20. This constitution separates thrust of an elevating cylinder 12 from the sucking pad 16 during lowering of the support member 14 and the sucking pad 16 is lowered to a sucking position under its own weight following lowering of the support member 14. Thus, thrust of the elevating cylinder 12 is not transmitted to a plate glass 32 through the sucking pad 16.

Title: Reduced image information reader
Inventor: NISHINO YASUKAZU
IPC: G09G5/36
Filed: 1987-11-19
Abstract: PURPOSE: To prevent the generation of an omission on reduced display information by setting up a sampling position of data for two-dimensional scanning as the same group within one horizontal scanning and setting up respectively different sampling positions in current horizontal scanning and succeeding horizontal scanning. CONSTITUTION: Sampling points are respectively differently set up in current horizontal scanning and succeeding horizontal, scanning so that the same sampling point, e.g. a sampling point 8, is set up in each block in a horizontal H1 line and a different sampling point, e.g. a sampling point 6, is set up in the succeeding horizontal line. Since a sampling point is set up in each horizontal scanning line, setting processing time can be completed within the horizontal flyback time of a display and access time to a memory can be executed at normal timing, the generation of an omission on reduced display information can be prevented.

The multiplexing device L1 once stores data D1 from the terminal T1 and data D2 from the terminal T2 and first transfers the data D1 from terminal T1 and later the data D2 from the terminal T2. The device L2 performs multiple separation of the data D1 and D2 from the terminals T1 and T2. In such a case, the data D1 and D2 from the terminals T1 and T2 surely arrive with data as lumps of the data D1 and D2 in turn respectively.

Title: Estimation of leakage area and leakage amount of gas
Inventor: NISHINO HARUO
IPC: G01M3/04
Filed: 1993-10-27
Abstract: PURPOSE:To quickly and correctly estimate a leakage area and a leakage point of a gas by calculating a gas flux from the density of the leakage gas detected by each gas detector and data on the wind direction and wind velocity in the vicinity of each detector and using a plurality of vectors of the gas flux. CONSTITUTION:For instance, gas detectors G1-G12 are arranged in matrix every 20m, and anemoscopes/anemometers B1-B4 are integrally set with the gas detectors G1, G4, G9, G12 at four corners. The data on wind directions and wind velocities are interpolated at the other detectors. A gas density and wind direction/wind velocity detected at all times are processed at a data processing device to operate a gas flux (a vector having a scalar of (density of leaking gas) X (wind velocity) and the direction of wind direction). The gas flux is displayed at a CRT. For example, the gas flux for three or more data in a preceding one hour is subjected to a regression analysis, and a maximum value and direction are represented by (m) and (n). An intersection is a leakage point of the gas and a part of oblique lines is a leakage area of the gas. When the gas flux exceeds a set alarming value, an alarm is issued and also the display of the maximum value and direction is changed, e.g. to red.
