Title: Associated hierarchical
Inventor: MAAKU DABURIYU MAIAA
IPC: G01S7/38
Filed: 1989-11-02
Abstract: PURPOSE: To deinterleave a signal pulse featured by at least two parameters by generating a model of itself based on the signal actually received. CONSTITUTION: The components of arrival words are frequency, arrival angle and time of the pulse. Respective pulse descriptive words 22 are compared with confirmed emitter 24. First to N-th confirmed emitters 26-1 to 26- N are mismatched, and hence compared with virtual emitter 30. Again, if it is mismatched with any of first to N-th virtual emitters 32-1 to 32- M, the words are disposed at one of first to K-th asserrablings 38-1 to 38- K. The emitter is a group of pulses formed of the assembling, and the description is started by the level of the assembling. The assembling is a group of words having similar values for the frequency and arrival angel, and the similarity is decided by using the predetermined allowable error, and the assembling step is substantially matching function. With the constitution, substantially complete deinterleave can be performed by the minimum hardware.

Title: Semiconductor device
Inventor: SATO MASAYUKI
IPC: H01L21/60
Filed: 1987-11-13
Abstract: PURPOSE:To reduce the connecting resistance of bump electrodes to wirings by so forming a pad larger than an opening on the opening as to connect it through the opening to the wiring, and providing the electrodes on the pad. CONSTITUTION:A pad 16P is connected through a connecting hole 15 to aluminum wirings 13. The upper face of the pad P16 is flattened. The area of the pad 16P is, since there is no restriction in the periphery, much larger than that of the hole 15, and can be formed, for example, 25 times or more as large as it. The pad 16P is covered by the substrate metal film 19 of the electrode 20B. That is, since the pad 16P having an area larger than the opening 15 is formed on the opening 15, the connecting area of the wirings 13 to the film 19 is equivalently increased. Here, when the diameter of the hole 15 is set to 10mum, the connecting resistance of the pad 16P to the wirings 13, i.e., the connecting resistance of the aluminum film to the aluminum film is <=0.01mOMEGA.

Title: Device for recording and reproducing digital audio signal
Inventor: TAKEMOTO SHINJI
IPC: G11B20/10
Filed: 1992-09-29
Abstract: PURPOSE:To record and reproduce a multi-channel digital audio signal on one track with simple circuit constitution. CONSTITUTION:The N channel audio signal is inputted to a miultiplexer 21, and is gathered at every M channel (M is a divisor of N), and is divided to the N/M pieces of sector signals. A channel number (ID code) is added to data in respective sectors by an ID addition means 22. The recording timing signals of respective sectors are impressed to a multiplexer 23 with a phase signal outputted from a phase detection means 9 by a recording timing generation means 10. At this time, a generated serial signal is recorded on a magnetic tape through a recording system RF processing means 3. Reverse signal processing at a recording time is performed at a reproducing time. In such a manner, the total number of bits in the ID code is reduced, and the multi-channel digital audio signal is recorded and reproduced on one track by time division.

Title: Testing device for digital-analog converter
Inventor: UENO TOSHIAKI
IPC: H03M1/10
Filed: 1985-12-20
Abstract: PURPOSE:To bring the conversion speed of a reference A/D converter to a low speed and to avoid the deterioration in the effective resolution by sampling the output of a D/A converter to be tested at a low speed synchronously with the conversion speed of the reference A/D converter. CONSTITUTION:A frequency synthesizer (1)7 generates a frequency f0 of a low phase noise specifying the conversion speed of a D/A converter 4 to be tested and a frequency synthesizer (2)8 generates a frequency fSPL specifying the conversion speed and sampling speed of the reference A/D converter 14. A pattern generator 9 generates a parallel data synchronously with the frequency f0 and makes the D/A converter 4 output an analog output. The analog signal is sampled at a low speed by a sampling head 11 and inputted to the reference A/D converter 14. Since the pattern generator 9 generates a pattern repetitively, the sampled waveform has a low frequency to test a high speed waveform.

Filed: 1988-11-10
Abstract: PURPOSE:To prevent a failure in photographing caused by errors in the operation for switching modes by providing a means for presetting data in accordance with a usual photographing mode when the counted value of a limit detection means exceeds a limit or when a detecting means detects that a manual operation is performed. CONSTITUTION:The title device is provided with a means for presetting the data in accordance with the usual photographing 16 mode in a counting means when it is detected that the counted value of the limit detection means exceeds the limit or when it is detected by the detecting means that the specific manual operation is performed in a camera. When a mode except the usual photographing mode 16 is set as the photographing mode with such a constitution, the usual photographing 16 mode is automatically set thereafter by performing a specific operation, for example, by operating a release button 1 once. Thus, the photographing mode is electrically switched just by operating an operational switch provided in the camera. Since the photographing mode where there are a few failures is automatically and electrically restored if the operation of the camera is performed, the failure in photographing caused by a user's forgetting that the mode is switched can be prevented.
