Title: Voice decoding system
Inventor: SUZUKI MASAMITSU
IPC: H03M1/66
Filed: 1986-07-14
Abstract: PURPOSE:To compensate the expected value of the data on the bits which are not transferred and to suppress deterioration of signals, by adding '1' to a digit lower by a step than the lowest digit of the code data produced by the semi-instantaneous compression when this data is decoded. CONSTITUTION:The coding data DL is applied to a demultiplexer 11 and head three bits are identified as the scale value SC for each block. This value SC is applied to the scale value input terminal of a semi-instantaneous expanding part 12 and other code data (compression data) are applied to the code data input terminal of the part 12 respectively. The pat 12 divides the received code data every four bits and at at the same time distributes these 4-bit data at the bit positions of the 8-bit data corresponding to the input data SC. Then the contents of the code data are set to the digits higher than the code data together with '1' set to the digit lower by a step and '0' set to the next lower digit respectively. Thus the 8-bit coding voice data is decoded and then undergoes D/A conversion 13.

IPC: G01R23/16
Filed: 1997-06-20
Abstract: PROBLEM TO BE SOLVED: To highly accurately estimate a spectrum, without synchronizing the spectrum with a pitch. SOLUTION: An approximately 3-5 ms minute section τ of an input sound waveform is sliced (S3) and subjected to DFT(discrete Fourier transform) with a Hamming window (S5). A spectrum of the τ, i.e., M=log(X+1) (X: a result of the DFT) is found (S6). A cumulative addition A=A+M<e> (an initial value of the A is 0) is performed (S7). The τ is shifted by 2-4 ms, and the slicing of the τ is carried out again (S8). The process is conducted for a conventional analysis section T, and S=(A/N)<1/e> (where N-1 is a count of shifts) is calculated to obtain a spectrum S (S10). This procedure is executed for each spectral component.

Title: Dead-soft cold rolled steel sheet excellent in spot weldability
Inventor: OGAWA KAZUHIRO
IPC: C22C38/32
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To improve the spot weldability of a steel sheet while its excellent workability is maintained by prescribing the contents of elements. SOLUTION: In this steel sheet, good spot weldability (nugget formability) is imparted by the addition of B, the nugget size and the hardened region of the heat affected zone expand, and the static strength and fatigue strength of the spot weld zone are made good even without the addition of Nb. Namely, B is the element effectively segregating in the grain boundaries and improving its hardenability. Furthermore, by the addition of B, the transformation point drops to expand the melting region. In this way, the strength and area of the substantial load-bearing part expand, therefore B improves its fatigue properties and static joint characteristics.  The content of B is preferably regulated to 0.0010 to 0.0030wt.% in consideration of deterioration in the trapping operation of solid solution N and the material (ductility in particular), and furthermore, the satisfaction of B>(11/14N) is the requisite.

Abstract: PURPOSE:To provide a selective call function calling a specific caller by adopting an in-band signal system for the connection control where one of two stations calls the other and inhibits the call and talking of the other station until the talking is finished. CONSTITUTION:A control circuit 11 turns on/off a switch 34 according to a channel selection signal of a call start station, an output of a 2,280Hz oscillator 33 is subject to FM modulation via a delay circuit 36 to form a transmission IF signal 102. When a channel selection signal is finished, switches 34, 38 are turned off and a reception switch 26 is turned on. When a called station detects a signal 102, the circuit 11 sets a busy tone oscillator 27 and inhibits turning-on of the transmission switch 38 for the period. When an incoming call is to the own station, the oscillator 27 is turned off and a call signal oscillator 28 is turned on. While a voice detector 35 of the call start station/a called station detects a talking signal, the switch 38 is kept off, and while the talking signal is detected during the other period, the switch 38 is turned on. When a station other than the call start station/called station detects the selection signal, the oscillator 27 is turned on and when the end of call signal is detected twice, the oscillator 27 is turned off to make the line idle.

Title: Combustion equipment and combustion method
Inventor: JIEFURII CHIYAARUZU BOOKAA
IPC: F23C6/04
Filed: 1995-06-06
Abstract: PURPOSE: To perform stabilized combustion of an ultra-lean mixture gas in order to reduce emission of NOx. CONSTITUTION: A first mixture of fuel and air is preheated by transferring heat from hot gas 40 discharging from a combustor 15. The preheated first mixture is then catalyzed in a catalytic reactor 86 and then combusted so as to produce a hot gas having a temperature in excess of the ignition temperature of the fuel. Second and third lean mixtures 84, 85 are then sequentially introduced into the hot gas, thereby raising their temperatures above the ignition temperature and causing homogeneous combustion of the second and third mixtures. This homogeneous combustion is enhanced by the presence of free radicals created during catalyzation of the first mixture. In addition, the catalytic reactor acts as a pilot that imparts stability to combustion of the second and third lean mixtures.
