Patent JP-S61115366-A (JP)
Title: Semiconductor laser device
Inventor: SHIMIZU YUICHI
IPC: H01S5/00
Filed: 1984-11-10
Abstract: PURPOSE:To reduce defectives due to electrical short circuits, which have been generated in an assembly process in the conventional method, largely by constituting p-n junction sections exposed to side surfaces except the end surface of a resonator for a semiconductor laser under the state in which the p-n junction sections are indented to the substrate side more than an internal p-n junction section. CONSTITUTION:p-n junction sections in the vicinity of side surfaces except the end surface of a resonator take constitution in which the p-n junction sections are formed recessed to the substrate side more than internal p-n junction sections. A proper protective film for preventing the deterioration of the end surface of the resonator is shaped onto the end surface. When a semiconductor laser is prepared by a cutting such as cleavage according to the constitution, sections made to be contained in the end surface of the resonator in the end sections of p-n junctions exposed in all directions are insulated electrically by the protective film, and the ends of the p-n junctions in side surfaces approximately vertical to these sections made to be contained in the end surface of the resonator are separated from the surface, and formed on the side nearer to a substrate. Consequently, when the laser is bonded by using a solder material while the surface is directed downward, electrical short circuit due to the creeping, etc. of the solder material can be prevented.

Title: Data control system for data base
Inventor: FUKUSHIMA YUKI
IPC: G06F12/00
Filed: 1990-09-07
Abstract: PURPOSE:To prevent the deterioration of performance of a data base by processing the requests after reception of the inquiry given from another data base if at least one of requests lacks. CONSTITUTION:A 1st data base 1A receives an answer from a 2nd data base 1B via a network 7 and then sends this answer to an inquiry processing part 5 through a command I/F 3. The part 5 sends the received answer into its own data base so as to use the answer like its own table. When plural inquiry sentences are sent to another data base the part 5 waits for arrangement of all answers. In this case, however, only a DOCTOR-LIST sends an inquiry sentence and therefore the arrangement of tables is reported to a command processing part 4. In such a constitution, the communication processing is never complicated and therefore the deterioration of performance is prevented for the data bases.

Title: Tuning fork type piezoelectric gyro sensor
Inventor: INOUE TAKESHI
IPC: G01C19/56
Filed: 1998-08-25
Abstract: PROBLEM TO BE SOLVED: To obtain a compact and high-performance gyro sensor by forming one or a plurality of layers of internal electrodes in parallel with the main surface of a piezoelectric ceramic tuning fork in one piece by sintering. SOLUTION: Internal electrodes 11-14 that become the same potential for drive, internal electrodes 17' and 17" that become the same potential for drive, internal electrodes 15 and 16 that become the same potential for detection, and another internal electrode 18 for detection are formed in an arm 21 at a drive side and an arm 22 at a detection side of a tuning fork. The material of a tuning-fork-type piezoelectric gyro is made of piezoelectric ceramic with improved temperature stability and is manufactured by the tape casting method. When the right half of the right-side arm 21 of the tuning fork is extended (shrunk) due to a piezoelectric side effect, a left half is shrunk (extended) due to the piezoelectric side effect.  In this case, coriolis force Fc operates in a direction perpendicular to vibration in the surface of the tuning force and voltage being generated by the coriolis force is detected from the electrical terminal of the left-side arm 22. The large part of the piezoelectric tuning fork is a piezoelectric active part and the interval between electrodes also decreases, thus obtaining a high-sensitivity gyro.
