Title: Magnetic recording and reproducing device
Inventor: HIROSE YOSHIHITO
IPC: H04N5/91
Filed: 1988-04-18
Abstract: PURPOSE:To attain follow-up recording without damaging a source video signal by delaying by one frame period a video signal reproduced from a magnetic tape where the video signal and a sound signal are frequency-multiplex-recorded on the same track and rerecording it together with the sound signal to be follow-up sound recorded on an erased track after the video signal is reproduced. CONSTITUTION:The video signal reproduced from the magnetic tape where the video signal and the sound signal are frequency-multiplex-recorded on the same track is delayed by one frame period and it is rerecorded together with the sound signal to be follow-up sound recorded on the erased track after the video signal is reproduced. Therefore, magnetic heads 12a and 12b for rerecording the video signal, magnetic heads 13a and 13b for follow-up sound recording, magnetic head for erasing able to erase only a necessary track, a frame delay circuit 16 to match a recording timing, etc., are added. Thus, the follow-up sound recording is attained without damaging the source video signal.

Title: Semiconductor light emitting device
Inventor: ISHIKAWA HIROSHI
IPC: H01S5/026
Filed: 1988-04-18
Abstract: PURPOSE:To reduce chirping created at the time of high speed modulation while the noise is maintained at a low level by a method wherein two active layers separated from each other by a distance with which optically light coupling is provided between each other, semiconductor layers whose conductivity types are different from that of a substrate, electrodes on the respective semiconductor layers and a capacitor are provided on the substrate. CONSTITUTION:Two stripe-form active layers 22 and 23 separated from each other by a distance with which optically light coupling is provided between each other are provided on a substrate 21 and semiconductor layers 27 and 28 whose conductivity types are different from that of the substrate 21, electrodes 29 and 30 and a capacitor 32 connecting between the electrodes 29 and 30 are provided on them and an electrode 31 is provided on the bottom surface of the substrate 21. Light output excited in the active layer 22 is detected in the active layer 23 and converted into an electric signal (photocurrent) in the active layer 23 and fed back through the capacitor 32. Therefore, as the surface reflecting the light does not exist between the two active layers 22 and 23, the variation of the operation state of a laser is not induced. With this constitution, chirping can be suppressed while the noise is maintained at a low level.

Abstract: PROBLEM TO BE SOLVED: To prepare a cast excellent in air permeability and high in compressing strength, by adding a nonionic surfactant to a main body consisting of a heat resistant material and hemihydrate gypsumas as a bonding member so as to make a burying material for dental casting. SOLUTION: A wax pattern 3 in the same shape of a casting body is prepared and the pattern 3 is planted at a rubber cover 41 and a ring 42 is set to the cover 41 to inject a slurried burying material 50 into the ring 42. The material 50 is coagulated by leaving alone for 20 minutes, e.g. after injection and thrown into a heating furnace of 700 deg.C atmosphere in the state of removing the cover 41 to keep 60 min to fusing and discharge the pattern 3 to obtain a cast 5 with a cavity 51. Then, the material 50 is obtained by adding the nonionic surfactant to the main body consisting of the heat resistant material and hemihydrate gypsumas as the combining member. In addition, a polyether- based surfactant its used as the nonionic surfactant.

Abstract: PURPOSE:To improve productivity of the mirror and enhance the molding accuracy thereof by providing a mirror part, which forms a polygonal mirror face, and shaft parts, which coaxially extend on both end faces of the mirror part, and further providing recessed parts on the end faces of the mirror part. CONSTITUTION:A polygonal mirror 1 consists of a regular hexagonal mirror part 2 and shaft parts 3 coaxially extended on both end faces of the mirror part 2 and is molded in a unitary structure with plastic.

Filed: 1987-04-20
Abstract: PURPOSE:To disable an operator to execute processing such as deposit with drawal unless a 1st code is known by displaying a 1st code in case of a correct personal identifying number input or a 2nd code in case of an incorrect identifi cation number input. CONSTITUTION:The operator 2 of an IC card 1 inputs a personal identification number through an information input part 11 such as a keyboard and stores the number in an input identification number storing part 12. The stores contents are compared with that of a registered identification number storing part 13 previously storing the identification number by a coincidence deciding part 14. At the time of coincidence, the 1st code previously stored in a 1st code storage part 15 is displayed on a display part 18 and the operator checks the display and depresses a transaction key to execute transaction. In case of discrepancy, the 2nd code is displayed and the operator inputs the identification number again. Since an incorrect card owner does not know the 1st code, deposit or the like can not be paid even if the input of the identification number is repeated several times.

CONSTITUTION:The post-processing of an address book reader is used as an example. The address book is recognized by a recognition part 1 and the recognized result is stored in a document buffer 7. The word stored in the document buffer 7 is compared with a word group registered in a post-processing dictionary 4 and replaced by the most similar word out of the words in the post- processing dictionary 4 and replaced by the most similar word out of the words in the post-processing dictionary 4. If there is no sufficiently similar word, an unregistered flag corresponding to the word is set up to ''1'' and only the word is displayed on a display device 5. The operator moved a cursor to the line of the displayed word and depresses a ''REGISTER'' key to register the word in the post-processing dictionary 4. When the word recognized in error, the word is corrected through keying and a ''RE-POST-PROCESSING'' key is depressed, the word is compared with the post-processing dictionary 4 again, and if there is no similar word as the compared result, the unregistered word is displayed.

Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To restrain ascending movement of a valve element under the condition of little contact friction resistance and reduce the number of part items by forming the upper end part of a valve shaft into a spherical face body of small radius of curvature, and bringing the spherical face body in contact with the top board part of a can body fixed to the upper part of a valve main body to regulate a valve full open position. SOLUTION: In a motor driven flow control valve applied to a refrigerating cycle and controlling flow of fluid, when the valve element 33 is on the full close position, by giving a pulse signal to the coil 22a of the stator part 22 of a motor 20, a rotor part 23 is rotationally moved to raise a valve shaft 31, and the valve element 33 is opened through engagement of the male thread part of a fixed guide 35 with the female thread part of a sleeve.
