Title: Noise suppressing device
Inventor: AKAHA MAKOTO
IPC: G10L21/0208
Filed: 1992-01-30
Abstract: PURPOSE:To suppress noise and to constitute the device simple and compact. CONSTITUTION:While referring to a code conversion table making codes bx of noise added sounds and code aj no noise sounds correspondent in the manner of probability, a code converter 5 coverts the code obtained by vector quantizing a linear predictive coefficient extracted from the noise added sound by a vector quantizer 4 to the code of the sound suppressing the noise of the noise added sound. On the other hand, a whitening part 9 converts the residual signal of the noise added sound outputted by a predictive filter 7 to an impulse sequence or white noise having the pitch cycle of the noise added sound. In a synthesizing filter 10, a sound model composed of the linear predictive coefficient calculated by the converted code is driven by the impulse sequence or white noise outputted from the whitening part 9, and audio signals are reproduced.

Title: Brazing fin material for heat exchanger made of aluminum alloy
Inventor: BABA YOSHIO
IPC: F28F21/08
Filed: 1980-03-31
Abstract: PURPOSE:To enhance the corrosion resistance, workability and buckling resistance of a brazing fin material by using an Al alloy contg. a small amount of Mn, Fe, Zn and Sn and having a specified grain size or above as a core material and an Al-Si or Al-Si-Mg solder alloy as a shell material. CONSTITUTION:An Al alloy consisting of 0.5-2% Fe+Mn (Mn exceeds Fe), 0.1-0.7% Zn, 0.001-<0.02% Sn and the balance Al and having >=100mum grain size is used as a core material. On the other hand, an Al-Si solder alloy is used as a shell material for flux brazing, or an Al-Si-Mg solder alloy for vacuum brazing. The core mterial is clad with the shell material to manufacture a brazing sheet, and this sheet is used as a fin material for the main tube of a heat exchanger made of Al alloy. Since the electric potential of the fin material becomes baser than that of the main tube, the pitting corrosion of the tube can be prevented.

Title: Data communication controller
Inventor: SHIMURA KIYOSHI
IPC: G06F13/00
Filed: 1985-03-01
Abstract: PURPOSE:To reduce the quantity of a microprogram of a communication control circuit and the hardware by providing a means adding count information representing the order of generation of the notice of end to an end notice. CONSTITUTION:An ending counter comprising a device such as a microprogram register, a memory or a hardware counter is built in a control section of a communication control circuit 3 and indicates the order of ending of commands. When the end of command is notice to a data processing section 1 via an interruption line 104 from the control circuit 3, the processing section 1 searches a word of a report block of the memory 2 and discriminates which command is to be finished. Furthermore, when >=2 commands are finished, the order of end of commands is discriminated by comparing next words. Thus, the command end processing is applied in the correct order and further, the processing section 1 searches periodically the word of the report block of the memory so as to attain similar effect even without the interruption line 104.

Title: Pellicle for protecting mask
Inventor: ONISHI YURI
IPC: G03F1/62
Filed: 1993-03-02
Abstract: PURPOSE:To prevent the change in the shape of a pellicle film by a fluctuation in the atm. pressure outside the pellicle by forming a hole in a pellicle frame and providing this pellicle frame with a film deformable according to a fluctuation in the atm. pressure so as to cover the hole of the pellicle frame. CONSTITUTION:The hole 14 is formed in a part of the pellicle frame 11 and the pellicle frame is provided with the film 15 deformable according to the fluctuation in the atm. pressure outside the pellicle so as to cover the hole 14. The method of installing the pellicle film 12 and a photomask 13 to the pellicle frame 11 is the same as the conventional methods. There is no change in the shape of the pellicle film 12 and the deformable film 15 in the case of an atm. pressure outside the pellicle but the deformable film 15 is made to be in a projecting state in the case of a drop of the amt. pressure outside the pellicle. A pressure difference between the outside and the inside of the pellicle is thereby offset and, therefore, the deformation of the pellicle film 12 to a projecting state does not arise. Since this pellicle for protecting the mask covers the hole 14 of the pellicle frame 11 with the film 15 deformable according to the fluctuation in the atm. pressure, the good state in the pellicle is maintained.

IPC: B60T8/66
Filed: 1978-04-10
Abstract: PURPOSE: To improve the reliability by preventing mulfunctioning using the frequency signal indicating the speed of wheels for control signal as it is.  
     CONSTITUTION: A counter 3 counts the speed of wheels detected as frequency signal in a frequency value per unit and outputs the count value to shift registers 6 and 7. The moment the braking starts, a subtraction circuit 11 subtracts the value of the shift register 15 from that of the shift register 6 each unit time and outpts the result to the shift register 6.

CONSTITUTION: A connecting cylinder 2 in a closed end cylindrical shape is fixed over the outer side of a metallic pipe which is a subject pipe for connection, for example, one of swelled-up sections 12 and 12 which hold the bottom plate 20 of the connecting cylinder 2 so as to fix it, is projected into a circular space A between a metallic pipe 1 and the connecting cylinder 2, and when an elastic pipe 4 is inserted into the aforesaid circular space A, the tip end section of the elastic pipe 4 is brought into contact with the swelled section 12, and a clearance is so constituted as to be formed between the connecting pipe 2 and the bottom plate 20 while a width (=X) equivalent to the swelled section 12 is maintained.  After that, strain produced in the elastic pipe 4 as the connecting cylinder 2 is squeezed, is dispersed by the swelling of the elastic pipe 4 to the side of the clearance, and the concentration of strain to the vicinity of a squeezing position is thereby relaxed.
