Title: Digital system for encoding subband of digital audio signal
Inventor: REIMONDO NIKORAASU YOHAN FUERU
IPC: G11B20/10
Filed: 1988-04-27
Abstract: A system for subband coding of a digital audio signal x(k) includes in the coder (1) a filter bank (3) for splitting the audio signal band, with sampling rate reduction, into subbands (p = 1, ....P) of approximately critical bandwidth and in the decoder (2) a filter bank (5) for merging these subbands, with sampling rate increase. For each subband (p) the coder (1) comprises a detector (7(p)) for determining a parameter G(p;m) representative of the signal level in a block (p;m) of M samples of the subband signal xp(k) as well as a quantizer (8(p)) for adaptively block quantizing this subband signal in response to parameter G(p;m), and the decoder (2) comprises a dequantizer (9(p)) for adaptively block dequantizing the quantized subband signal sp(k)in response to parameter G(p;m). The quantizing characteristics are related to the noise-masking curve of the human auditory system, owing to which a high-quality of the replica x/< ANd >(k) of audio signal x(k) is attained with an average number of approximately 2.5 bits per sample for representing the output signals of the coder (1). The occasional audibility of quantizing noise in this replica x/< ANd >(k) is reduced effectively in that the coder (1) and decoder (2) contain identical bit allocation means (23, 24) responsive to a set of parameters G(p;m) for the higher group of subbands (pim</=p</=P) within an allocation window (Fig. 5) for allocating a number of B(p;m) bits per sample from a fixed predetermined number of B bits for this allocation window to the quantizer (8(p)) and the dequantizer (9(p)) for the block (p;m) of subband signal xp(k) and sp(k), respectively.

Title: Data preservation device and hierarchical data preservation system
Inventor: SHIRAISHI TOSHIHITO
IPC: G06F17/30
Filed: 1994-05-18
Abstract: PURPOSE:To provide a hierarchical data preservation system with improved extendability. CONSTITUTION:The data preservation devices 1a-1c are hierarchically interposed between a network N and a lowest data preservation device 2. The data preservation devices 1a-1c are composed of controllers 11a-11c and data storage devices 12a 12c. When data are supplied from a host device, the controllers 11a-11c store the data in their own data storage devices 12a 12c or transfer the data to the low-order data preservation device by a prescribed judgement standard. When a data request is supplied from the host device, their own data storage devices 12a-12c are retrieved and the pertinent data are taken out and sent out to the host device when they are present. When the pertinent data are not present, the data request is transferred to the lower-order device and when the pertinent data are sent from the lower-order device, they are transferred to the host device. Thus, when the number of the hierarchically connected data preservation device is increased/reduced, constitution is easily changed so as to provide storage capacity suited to the required capacity of the data capable of being taken out within practical response time at all times.

Title: Protective circuit of autotransformer for voltage regulation of x-ray tube
Inventor: KOBAYASHI ICHIRO
IPC: H01F27/00
Filed: 1987-04-28
Abstract: PURPOSE:To prevent the generation of abnormal heat and the damage by a fire at coils and brushes of an autotransformer even at a shift in a position of the brushes by a method wherein a circulating current flowing between the brushes is detected and, when this current exceeds a prescribed value, it is shut off collectively between the brushes and between output terminals of the transformer. CONSTITUTION:When a switch 9 is closed and contacts 7, 7 are closed, a voltage V0 is output. During a normal operation, i.e., when brushes 3b, 3b are not shifted, a circulating current I does not flow. When the brushes 3b, 3b are shifted, the circulating current I flows between the brushes 3b, 3b; its partial current I' flows to a fuse 5. By this current, the fuse 5 is blown; the current I' is shut off; an alarm contact 6 is closed; a relay 8 is turned off; make-and-break contacts 7 are opened. By this setup, the circulating current I is shut off; coils 3a, 3a and the brushes 3b, 3b do not generate heat. Because the circulating current flowing between the brushes is detected and the brushes and output terminals are shut off, it is possible to prevent the generation of abnormal heat and the damage by burning of the coils and the brushes even when a position of the brushes is shifted.

Filed: 1980-07-28
Abstract: PURPOSE:To reject the noise each frame without the processing of interpolation, by decoding a digital information through the delay of a quantitized width information of a frame by a reception time. CONSTITUTION:A time series signal (a) is sectioned with a specific time interval, and the quantitized width is changed according to the maximum value of a signal at respective sections (frame) for a quasi-instantaneous compression, allowing to convert an original signal into a digital code and a quantitized width information Q. In the decoding (expansion) of the original signal, as shown in Figs. b, c, the information Q is received at the beginning of the frame and then the digital code in the frame is received to sequentially decode each digital code with a delay by the reception time of the quantitized width information than the original signal (a) in time series. The error per frame due to this time delay can not be noise, because it can be neglected on human audible sense.

IPC: B60W10/10
Filed: 1987-04-27
Abstract: PURPOSE:To eliminate unnatural feeling of driving at the time of a sudden change in a load condition in a vehicle where a target engine rpm is set corresponding to throttle opening, etc. by limiting a slow-down ratio of the target engine rpm per unit time. CONSTITUTION:An electronic control device 60 for inputting various output signals from an engine rpm sensor, vehicle speed sensor, shift position sensor, throttle opening sensor, etc. sets a target engine rpm corresponding to throttle opening. The control device 60 also controls the speed change ratio of a continuously variable transmission 10 by controlling a solenoid 44 for controlling a pulley so that the engine rpm approaches the target engine rpm corresponding to throttle opening at that time. In this case, the electronic control device 60 is provided with a means for limiting a slow-down amount of the target engine rpm per unit time. This causes the engine rpm, when the throttle is fully closed during driving, to slow down with a time gradient to the target engine rpm to eliminate unnatural feeling of driving.

Title: Test method for common line data transmission link
Inventor: TSUKADA NORITAKA
IPC: H04L69/40
Filed: 1984-05-23
Abstract: PURPOSE:To attain the continuous test of a data transmission link despite hit of a carrier wave occurs by deciding a defective decision result for the output of a deciding circuit during the hit of carrier wave and resetting the deciding circuit to its original state when the hit is recovered and at the same time adding a carrier wave break countermeasure circuit to a deciding pseudo random pattern generating circuit. CONSTITUTION:When hit of a carrier wave break arises at a data transmission link 1, a carrier wave break countermeasure circuit 9 detects a carrier wave break detection signal 10 and decides a defective decision result for the output of a deciding circuit 7. Thus an error counter circuit 8 can count the bits. When the hit of carrier wave is recovered, the circuit 7 is reset to its original state. At the same time, a reception circuit 5 sets a pseudo random pattern to a deciding pseude random pattern generating circuit 6 after the hit of carrier wave is recovered and for a period during which the next pattern is received after a 9-bit data pattern is received first. In other words, the test of the link 1 is continued even after the recovery of the hit of carrier wave by synchronizing the circuit 6 with a pseudo random pattern generating circuit 4.
