Title: Trespasser finding device
Inventor: HASHIMOTO TAKESHI
IPC: G08B25/10
Filed: 1992-02-14
Abstract: PURPOSE:To find a trespasser, etc., with reliability by comparing a signal stored in a memory with the output of a detection part and deciding whether or not a specific level difference is generated. CONSTITUTION:The carrier oscillation part 5 of a transmitter generates a carrier of frequency fc and the carrier is transmitted from an antenna 6. The antenna 7 of a receiver receives the carrier of frequency fc and after unnecessary frequency components other than the carrier are removed by a BPF 8, an amplification part 9 amplifies the carrier. The detection part 10 detects the envelope of the amplified carrier and inputs level information on the carrier to a storage part 11 and a comparison part 13. The comparison part 13 operates with a switch 14 ON and compares the level information on the received signal from the detection part 10 with sequentially updated level information on the received signal from the storage part 11 to generate a detection signal when a level difference is generated, thereby detecting the trespasser.

Title: Document data processing method and document processor
Inventor: NAGANO YOSHIHIRO
IPC: G06F19/00
Filed: 1995-03-20
Abstract: PURPOSE: To efficiently process documents by verifying a processing result and skipping a specific number of following processing phases for document data after processing when the processing result meets specific conditions. CONSTITUTION: The document data which are received by FAX 20 and recognized at a recognition part 22 are stored in a file 25 while having its processing status set to 'wait for input'. When a processing terminal 40 specifies 'wait for input', the document data in the 'wait for input' state are extracted in the recognition order and sent to the terminal 40, which performs correction processing. When the data are not corrected, the status is set to 'wait for approval' by skipping 'wait for confirmation', but when the data are corrected, the status is set to 'wait for confirmation'. In input processing, the amount of money is collated with the set amount of money and the status is set to 'wait for approval' by skipping 'wait for confirmation' when the amount of money is less than the set amount of money and no correction is made.  In approval processing, an operator requests 'wait for confirmation' unless there is 'wait for approval', and performs confirmation processing. If a miss is found, the status is put back to 'wait for input' and re-input processing is performed.

Title: Large-sized bolt lower nut screwing device
IPC: F01D25/24
Filed: 1992-03-17
Abstract: PURPOSE:To provide a large-sized bolt lower nut screwing device capable of automatically fixing a lower nut of a large-sized bolt for tightening a steam turbine high pressure casing without galling in suspending and screwing. CONSTITUTION:In fixing and screwing a lower nut 2b, the lower nut 2b and a nut support table 6 are fixed to a lifting wire 4, to be connected to the lower end of a screwing shaft 5. The connected lower nut 2b receives specified winding force by a winding-up adjusting mechanism 15. The screwing shaft 5 is fed upward by the same lead as that of a screw of a bolt 3, thus starting screwing. In the case of generation of an overload, winding operation is automatically stopped, thereby preventing generation of abrasion. Consequently, it is possible to enhance reliability and reduce manhours because galling and operating fluctuation by an operator cannot be generated owing to automatic management and adjustment of the screwing force. Furthermore, a screwing device can be used anywhere without limitation of an installation site and space.

Abstract: PURPOSE:To ensure easy attachment of a sheet web and simple solution of a paper jam problem by parking a paper powder brush from a recording sheet web transport path which swingingly opens with a main printer system, interlocked with the swingingly opening action of an upper opening member. CONSTITUTION:A cover 2 which is an upper constituent member is attached to a main device system 1 in such a manner that the cover 2 can be swingingly opened and a fanfold sheet transport path 3 is formed between the main device system 1 and the cover 2. In addition, paired paper dust brushes 5 are arranged near an introduction member for the fanfold sheet transport path 3. The paired paper dust brushes 5 consist of two pieces of brush 51, 52 attached horizontally over and under a brush holder 53. Then if the cover 2 swingingly opens, the pressure of a lever 6 by a lever operation part 22 is released, so that the lever 6 is rotated at a specified angle by a spring 63. Subsequently, a paper dust brush operating arm 61 pushes up a holder arm 53B which holds the brush 51 to give an oscillating action to the holder arm 53B. Thus the upper brush 51 is allowed to move upward over a specified distance to an immobilization position, leaving a specified amount of space between the paired paper dust brushes 5.
