Title: Digital power switch circuit
Inventor: MOCHIZUKI HIROTAKA
IPC: H03K17/08
Filed: 1990-04-11
Abstract: PURPOSE:To perform automatic-reset overcurrent protection without a bad influence upon peripheral apparatus by controlling turning-on/off of a power FET in accordance with a binary logical signal of the high level and the low level and limit ing the current by linear control. CONSTITUTION:A gate driving circuit 2 which controls turning-on/off of a power FET (MOS transistor) 1 in accordance with a binary logical signal of the high level and the low level and a circuit means 4 which causes the power FET 1 to limit the current by linear control are provided. If a current Io flowing to the power FET 1 exceeds a prescribed value determined by a reference level Vref because of short-circuit of a load or the like, this state is linearly negatively fed back to a gate voltage Vg of the power FET 1 through a current detecting means 41, an amplifying circuit 42, and the gate driving circuit 2. That is, the current Io is limited to the prescribed value or lower determined by the reference level Vref. Thus, automatic-reset overcurrent protection is performed without a bad influence of malfunction upon peripheral apparatus.

IPC: H01L29/06
Filed: 1983-05-30
Abstract: PURPOSE:To improve dielectric resistance between a source and a drain without increasing ON resistance by forming a first source electrode being in contact with a source region and a second source electrode arranged through a thick insulating film. CONSTITUTION:A second source electrode 13 is disposed onto the surface of an epitaxial layer 2 held by a channel forming region 3 through a gate oxide film 5 and a second oxide film 12, and connected to a first source electrode 14 being in contact with the channel forming region 3 and an N<+> type source region 4. Since the sum of the second oxide film 12 and the gate oxide film 5 is thicker than the thickness of the gate oxide film 5 positioned under gate electrodes 6, the elongation of a depletion layer 15 generated by the second source electrode 13 is inhibited, the rise of ON resistance can be suppressed to a low value, and depletion layers 10 extending to the epitaxial layer 2 from the channel forming region 3 are connected mutually, thus improving dielectric resistance between a source and a drain.

IPC: H04L47/43
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To decrease a range of an error in discrimination by discriminating whether or not a time required for decoding of a frame exceeds a 2nd period for each 1st period. SOLUTION: In each connection, prev201 , 20i ,... and status 211 , 21i ... are read. When a frame is being assembled, a subtractor 13 subtracts the prev of the connection from a current time to obtain a difference (x). Information relating to a cell finally received is stored in the prev and the difference (x) indicates a lapse of time after the cell is received finally with respect to the connection. When the lapse of time (x) is larger than an assembled timer (RT) value by the comparison at a comparator 14, it is discriminated to be the RT end and error processing is conducted, (e.g. a frame being assembled is aborted) so as to relieve the area of the memory having stored cells belonging to the frame. When the lapse of time (x) is smaller than the RT value or in the case of error processing, expiration of time of a timer 11 is confirmed.  That is, each processing is repeated for each period T2.

Title: Method for measuring catalytic activity of active carbon
Inventor: HAMAZAKI ISAO
IPC: B01J21/18
Filed: 1994-05-11
Abstract: PURPOSE:To measure the catalytic activity conveniently by adding a solvent, reactive through the catalytic action of active carbon, to the active carbon and heating the active carbon at a temperature lower than the melting point of the solvent and then measuring the heating value. CONSTITUTION:Methyl ethyl ketone, methyl propyl ketone, methyl butyl ketone, etc., having melting point of 80-220 deg.C, is preferably employed as a solvent reactive through the catalytic action of active carbon. The solvent is added to the active carbon by spraying, mixing or immersion. Heating is normally performed at a temperature 10-60 deg.C lower than the melting point. The heating value is measured by means of a differential scanning calorimeter or a differential thermal analyzer. For example, 1.8g of dry active carbon is immersed into a solvent of about 0.2g and stirred for about 1 hour to prepare an active carbon containing the solvent. It is then heated at a temperature lower by about 20 deg.C than the melting point of the solvent by means of the differential scanning calorimeter and brought into contact with the air thus measuring the heating value. It has correlation with the amount of byproducts produced through the catalytic action and can be employed as an index of catalytic activity.

Filed: 1983-05-31
Abstract: PURPOSE:To keep a metastable time constant and invariable, and to obtain a square wave output of a prescribed width by connecting one input terminal of the second CMOS-NOR circuit to an output terminal of the first CMOS-NOR circuit, through a series circuit of a capacitor and a protective resistance. CONSTITUTION:Voltage of an input terminal g21 of the second CMOS-NOR circuit N2 is clamped instantly to power supply voltage VDD by a clamping diode DC the moment a curcuit state is reset to a stable point, also an unnecessary excessive current of a forward direction does not flow to a gate protective diode Dp1 of the inside of the CMOS-NOR circuit by a protective resistance RO, and a circuit operation which is stable and has a high reliability can be obtained. Also, since a perfect clamping effect is obtained, a metastable time tW can be made variable stably and continuously extending over a wide range by a variable resistor R, and also the voltage of the input terminal g21 is recovered instantly to the power supply voltage VDD, therefore, even in case when a trigger period T approaches the metastable time tW, the metastable time tW is not varied by the trigger period T, therefore, a square wave output of a prescribed width can be obtained.

Title: Speech recognition method and speech signal processor
Inventor: LAURILA KARI
IPC: G10L15/065
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To correct a feature vector to be decided at a speech recognition time for correcting the effect of a noise by defining the mean value and the standard deviation of the characteristic vector, using these parameters and normalizing the characteristic vector. SOLUTION: The mean value and the standard deviation of the characteristic vector are defined, and the feature vector is normalized using these parameters. In such a case, the feature vector is normalized using a sliding normarization buffer preferably. In a speech recognition device, a front end 30 forms the feature vector Xi (i=1-M) at a prescribed interval. The feature vector X is stored in a normalization buffer 31, and thus, the mean value and the standard deviation related to respective feature vector components Xi are calculated. Thereafter, the feature vector component Xi to be recognized is normalized using a calculated normalization coefficient in the block 31. In such a case, the normalization buffer 31 that e.g. a length N is fixed is slid on the feature vector X.
