IPC: B01D39/20
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To form a uniform collecting layer at an inner surface with respect to a production method and a production device for a ceramic filter element applied to a dust collector of a dust-containing gas generated from a boiler, a coal gasifier, etc. SOLUTION: In the ceramic filter element 3, the upper part is stopped with a cap 5 and the lower part is stopped with a plug 4, and a nozzle pipe 10 and a differential pressure gauge 11 are inserted into the cap 5. An air flow is introduced to an injector 9 from a blower 6 through a flow rate control valve 7 and a flowmeter 8, and ceramic particles are made to flow into the injector 9 from a hopper 12 for storing the ceramic particles by a feeder 14 rotated with a motor 13, and the ceramic particles are blown off into the element 3 from the nozzle pipe 10 together with the air flow. The air is made to flow out to the outside of the element 3 like (d) in the figure, the particles are stuck to the inner surface, and the collecting layer is formed on the surface of a skeletal layer of the element 3.  Adhered particles are uniformized since a difference between the internal pressure and the external pressure becomes uniform by closing the inside of the element 3 with the cap 5 and the plug 4, and the flow rate and the differential pressure are controlled.

Title: Nonconsumable electrode for welding
Inventor: KONO HITOSHI
IPC: B23K9/29
Filed: 1988-03-31
Abstract: PURPOSE:To extend the service life of a nonconsumable electrode type torch used for TIG welding by arranging a water-cooled electrode having double-wall structure to perform a function of a water-cooled jacket between the periphery of a slider to extend the electrode and an insulating cover of the outermost periphery. CONSTITUTION:When a cap 13 of the upper part of the slider 17 is turned the cap 13 is pressed downward in the axial direction by a screw action and hits on a tapered hole of the tip of the slider 17 and since the tip of the collet 2 is split, it is subjected to elastic deformation in the direction where the diameter becomes smaller to fix the electrode 1. Water-cooled electrode constituent members 18, 19 and 20 are formed to the integrated double structure and water- cooled. The tip thereof comes into contact with the central electrode, by which it is water-cooled indirectly. When electricity is supplied to a terminal and an arc is generated and continued between the electrode and base metal to perform welding, since the electrode tip has the small diameter, melting is not proceeded and its shape is maintained. Accordingly, afterward, the electrode is not consumed suddenly.

Title: Speaker recognizing method
Inventor: MATSUI TOMOKO
IPC: G10L15/06
Filed: 1990-03-26
Abstract: PURPOSE:To improve the speaker recognition rate by finding similarity from the size of the overlap of the distribution of an input voice and the distribution of a standard pattern and the distance between elements of the overlap part. CONSTITUTION:The similarity is found by using the calculation results of a part 11 which counts samples in the input voice included in the overlap part of the distribution of the input voice and the distribution of the standard pattern and a part 12 which calculates the distance between elements of the overlap part. Therefore, when the input voice contains a phoneme which does not appear during the generation of the standard pattern, the distribution of the feature parameter of the phoneme is much different from the distribution of the stan dard pattern and the overlap part becomes small, namely, the similarity increases. When the distribution of the input voice is very similar to that of the standard pattern, the overlap part becomes large and the similarity decreases, so that the similarity can correctly be known. Consequently, the speaker recognition rate can be improved.

Title: Voltage level converter
Inventor: BROWNLOW MICHAEL JAMES
IPC: H03K3/356
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of a voltage level converter by converting an input signal of a 1st voltage level into an output signal of a 2nd voltage level, charging or discharging a circuit node against a 3rd voltage level during a 1st period, separating the circuit node from a 1st voltage supply source during a 2nd period and then charging the voltage according to the input voltage during a 3rd period. SOLUTION: A PRECHARGE signal has a high level in a standby phase. An NMOS transistor TR M2 discharges the gate of an NMOS TR M4, and a PMOS TR M3 charges the inputs of the output CMOS inverters M5 and M6 up to voltage VDD. Under such conditions, there is no conduction path from the supply voltage VDD to the ground and accordingly the power consumption is decided in a static state by only the leakage currents in both inverters M5 and M6. In the following active phase, the PRECHARGE signal has a low level and a node A is separated when the TR M3 is switched off.

IPC: H04N19/40
Filed: 1995-03-09
Abstract: PURPOSE: To provide a rate conversion device for image encoded data which has performance similar to trans-encoding by using a means which is simpler than the trans-encoding. CONSTITUTION: Image encoded data 1a which are inputted from an encoded data input terminal 1 and encoded at an encoding rate R1 are supplied to a variable length decoder 2. The variable length decoder 2 decodes the data after variable length encoding and DCT encoding information 2a is inputted to an inverse quantizer 3. A quantizer controller 5 finds a quantization step required for requantization to control a quantizer 6. The DCT encoding information 2a quantized inversely by the inverse quantizer 3 is restored to a DCT coefficient 3a. This DCT coefficient 3a is quantized again by the quantizer 6 in a quantization step Q determined by the quantizer controller 5 and inputted to a variable length encoder 7. The variable length encoder 7 outputs image encoded data 7a, encoded at an encoding rate R2, to an encoded data output terminal 8 after the variable length encoding.

Abstract: PURPOSE:To realize a high-speed test for an integrated circuit of the multistep dividing circuit without increasing the number of pins but by resetting a rear step part of the dividing circuit by means of several units of the gate circuit and the latch circuit and then cancelling the reset at the supply time of the external pulse to start counting at the rear step part.

And FETQ1, Q2 set the output part to the pin of the circuit for other use under the high impedance state, and furthermore gates G4, G9 and G10 plus latch LT1 reset the rear-step part of the dividing circuit and then cancels the reset when the external high frequency pulse is supplied from the pin. Thus the counting is started at the rear-step part. In this way, the high-speed test is possible for the integrated circuit incorporating the multistep dividing circuit and without increasing the number of pins.
