Title: Pyroelectric infrared sensor
Inventor: KISHIHARA HIROYUKI
IPC: G01J1/02
Filed: 1993-11-30
Abstract: PURPOSE:To enable a pyroelectric infrared sensor to always detect infrared rays with the maximum sensitivity irrespective of the diameter of an infrared beam by constituting the infrared ray receiving section of an electrode of a photoconductive material. CONSTITUTION:The main body 2 of a pyroelectric infrared sensor is provided with a platy pyroelectric body 5 constituted of the crystal of LiTaO3, etc., and electrodes 6 and 7 respectively formed on the front and rear surfaces of the pyroelectric body 5. A discoid light receiving section 6a formed at the central part of the electrode 6 is formed of such a photoconductive material as PbS, HgCdTe, etc., and connected to the pyroelectric body 5 by, for example, vapor deposition. Usually, when the section 6a constituted of the photoconductive material which is usually an insulating material is irradiated with an infrared beam, the irradiated part becomes a conductor and functions as an electrode. Since the size of the part of the pyroelectric body 5 which generates electric charges when the part is irradiated with infrared rays coincides with the size of the part of the section 6a which becomes a conductor, the diameter of the infrared beam always coincides with the size of the part of the section 6a which functions as an electrode irrespective of the diameter of the infrared beam.

Title: Method for storing data for database
Inventor: ICHIKAWA MAMORU
IPC: G06F12/00
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To provide the effect of clustering even in an index whose overlapping degree is low and to sufficiently narrow data through the use of the same index by executing a clustering storage processing on key values overlapped with the value of the front item of index constitution items in the storage processing of data having the index constituted by plural arbitrary items in a database management system. SOLUTION: The system has a file storing inputted data. The index is constituted by the plural items among the items constituting data (4). When the key value machined with the key value of added data exists in the file (42), data is stored physically near data which is previously stored and has the same key value on the file (43). When the key value matched with data to be added does not exist in the file, data is stores behind stored data or in an overflow area (44). In such a case, the storage position of data is decided in the same way as the mentioned method in accordance with the presence or absence of the key value where the item of the front part among the plural items constituting the index is partially matched.
