Title: Rolling bearing with seal device
Inventor: MITSUE NAOKI
IPC: F16J15/3252
Filed: 1996-01-19
Abstract: PROBLEM TO BE SOLVED: To improve the sealability so as to effectively prevent the intrusion of the foreign material such as slurry into a ball installation part. SOLUTION: At the time of use, an inner ring 12 is not rotated and an outer ring 1 is rotated. A peripheral edge of a first seal ring 13 opposite to an outside space is locked with the inner peripheral surface of an end of the outer ring 1, and a second seal ring 14 opposite to a ball 5 is locked with the peripheral surface of an end of the inner ring 12. Since the first ring 13 is rotated at the time of use, the foreign material adhered to the outside surface of the first seal ring 13 is shaken off.

Title: Adder of pcm signal
Inventor: WAKAHARA YASUSHI
IPC: G06F7/38
Filed: 1980-01-28
Abstract: PURPOSE:To make possible high-speed operation with a small circuit scale by making digit matching of step values in SG according to the difference in the segment SG values of PCM signals and making predetermined calculations with two adders. CONSTITUTION:The bit components of SG values out of the absolute value of the input PCM signals from terminals 10, 11 are applied to a subtractor 30 and OR circuits 39, 40, and the bit components of the remaining step values are applied to shift registers SRs 35, 36. The subtractor 30 applies the absolute value of the differences in the SG values to a pulse generator 31, and applies the bit showing the magnitude of the SG values to a gate 34 and to a gate 33 via an inverter 32. When the input absolute value from the terminal 10 is larger than that from the terminal 11, the pulses from the generator 31 are applied to the SR36, so that it is shifted in the direction of lowering digits by the number of said pulses. In a converse case, the SR35 is shifted. The outputs of the SRs 35, 36 are inputted to an adder 37, by which they are added in such a state that they are converted to a linear signal, and if the overflowed bit is 1, this information is applied to an adder 38, by which it is added to the information from the subtractor 30, whereby the correct SG value is obtained.

Abstract: PROBLEM TO BE SOLVED: To superimpose digital watermark information on audio signals without lowering the quality of the audio signals while raising resistance against various signal processings. SOLUTION: Input audio signals are converted to frequency spectrum signals in an MDCT calculation part 12 by MDCT and the spectrum signals whose signal level is equal to or higher than a prescribed level obtained from the peak of the input signals are selected in an adaptive selection part 14. For 1 bit which is an n-th bit from the LSB of the successively selected spectrum signals, the digital watermark information is successively replaced in a bit operation part 15. The bits of an order lower than the n-th bit are replaced with a specified value for not making the n-th bit be influenced by an addition/ subtraction processing to the LSB. The frequency spectrum signals on which the digital watermark information generated in such a manner are returned to original digital audio signals in an IMDCT calculation part 16 and outputted.

Title: Light emitting diode
Inventor: MATSUDA MOTONOBU
IPC: H01L33/62
Filed: 1981-01-22
Abstract: PURPOSE:To obtain high light emission efficiency in a light emitting diode by absorbing heat produced in a P-N junction region in the vicinity of the side face in the region corresponding to the part of a light shielding mask, thereby suppressing the increase in the temperature. CONSTITUTION:An LED is composed of a junction of a P type semiconductor layer P2 and an N type semiconductor layer N2. An electrode A2 is provided at a partial region contacted with the side face 10, from which a light e is emitted, is provided on the top surface of the layer P2, and a light shielding mask A3 of insulated state from the electrode 2A is formed at the part except the electrode A2. In an LED thus constructed, when a current is supplied to the electrode A2, a current is flowed mainly to the region in the vicinity of the side face 10 and is not considerably flowed to the region provided with a mask A3. Accordingly, the temperature rise of the latter region is less than that of the former region. Therefore, the heat produced from the former region can be absorbed by the latter region, thereby suppressing the temperature rise at the P-N junction region in the vicinity of the side face 10, thereby obtaining the LED having good light emission efficiency.
