Title: Data base retrieval system
Inventor: TAKADA HIROSHI
IPC: G06F17/30
Filed: 1992-02-07
Abstract: PURPOSE:To increase the retrieval speed and to use the retrieval result again in the data base retrieval system using complicated conditional expressions. CONSTITUTION:Retrieval on prescribed conditions A, B, etc., is performed in a retrieval part 12, and retrieval results are stored in a retrieval result list storage part 14. In the case of retrieval on complicated conditions such as A or B, A and B, an object list condition retrieval part 16 uses the results of retrieval on conditions A and B, which are stored in the retrieval result list storage part 14, to perform the retrieval. Since the data base is not directly retrieved on complicated conditions, the retrieval time is shortened. Since results of retrieval on simpler conditions are used again, the retrieval efficiency is high.

IPC: H02G3/04
Filed: 1992-02-08
Abstract: PURPOSE:To provide a conduit for communication line in which damage at a bent or breakdown due to twisting can be prevented at the time of laying the conduit while furthermore minimum curvature of communication line can be ensured. CONSTITUTION:A conduit 1 having cross-section shown in fig.(A) is formed by winding a stripe material having S-shaped cross-section as shown on fig.

IPC: G02B5/124
Filed: 1988-03-10
Abstract: PURPOSE: To surely detect a beam by utilizing the displacement of the beam caused by a retroreflection mirror having three mirrors.  
     CONSTITUTION: A light source 20 is positioned in a light emitting and receiving device 14 and irradiates a lens 18 having the pupil 15 of the light emitting device and, as a result, a parallel light beam 21 is produced. A light receiving lens 19 is positioned near the lens 18 in the device 14 and a photodetector 22 is positioned to the focal surface of the lens 19 on the rear side of the lens 19. A retroreflection reflector 13 using a large number of reflecting mirrors 11 having three mirrors is constituted so that each reflecting mirror 11 can have a large bottom face B. Accordingly, the displacement V of the beam 21 caused by the mirrors 11 increases and a sufficient quantity of light enters the lens 19 and is received by the photodetector 22 even when the reflector 13 is positioned near the device 14. Therefore, the lgiht receiving signal of photodetector the 22 when the reflector 13 is positioned at a near distance does not change substantially from the light receiving signal when the reflector 13 is positioned at a far distance. Thus the beam 21 can be detected surely.

Filed: 1985-03-20
Abstract: PURPOSE:To operate efficiently a relay system while suppressing the probability of failure of retransmission by deciding a retransmission waiting time of relay request with the number of originals, the number of destinations and mean transmission time for one original at the preceding communication. CONSTITUTION:When the number (m) of reception stations A-Z is inputted by using an input key 8, the number (m) is set to a register 9. In depressing a transmission button 10 next, a call signal CA is sent from a control section 11. Then a start command ST is sent, an original is subjected to read 12 and compression 13, the result becomes picture information G and stored in a memory 14. The picture information G is sent to a relay station 3 and a page counter 16 counts the number of sheets of the original after sending. The relay station 3 receives the picture information of sheets of originals and applies sequential/ simultaneous multiple address to the reception stations A-Z. If the capacity of the storage section 4 is deficient in this process, the relay station 3 sends a signal NG informing disabled reception to a transmission station 1. Then each transmission station makes recalling of the relay station in response to the recalling time obtained from the information such as the number of originals sent already.

Thus 2<8> (=256) pieces of 9-bit signals are selected and stored previously to a ROM102 in response to the number of 8-bit input signals. Then the corresponding 9-bit signal is read out to a register 103 every time the 8-bit input signal is stored to a register 100. In such a way, the data code conversion with high accuracy is attained.

IPC: G06K19/00
Filed: 1987-03-13
Abstract: PURPOSE:To obtain a portable electronic equipment which can reduce processing programs by using one instruction as plural instruction for writing data in a data memory. CONSTITUTION:When a record number added to instruction data is 0 at the time of writing data in the data memory 16, a control element 15 writes the data from an address indicated by a write pointer. Further, when the record number is 1, on the other hand, the element judges that the data is an area specifying and rewriting command and rewrites data from an address of the area corresponding to the record 1. Further, when the record number is 1-N, the element judges that the data is a record specifying and writing command and rewrites data from an address the area corresponding the record number 1-N. Thus, the area specifying and writing command, area specifying rewriting command, and record specifying and writing program are put into one. Three similar processing programs can be put into one common processing program and reduced.
