Filed: 1994-04-26
Abstract: PURPOSE:To accurately and stably detect the generation of a wind noise by comparing a period wherein the polarity of the multiplication signal generated by multiplying two speech signals is positive with a period wherein the polarity is negative at every specific periods. CONSTITUTION:A multiplier 3 multiplies the signals outputted from low-pass filters 1 and 2 by each other and outputs the signal indicating the multiplication result. A polarity discrimination unit 4 discriminates the polarity of the signal outputted from the multiplier 3 and outputs a signal indicating '1' to a positive- polarity counter 5 and a signal indicating '0' to a negative-polarity counter 7 when the polarity of the signal outputted by the multiplier 3 is positive or a signal indicating '0' to the positive-polarity counter 5 and a signal indicating '1' to the negative-polarity counter 7 when negative. A comparing circuit 8 makes a large/small comparison between the count values of the counters 5 and 7 at every specific periods and outputs a signal indicating the generation of the wind noise when the count value of the counter 5 is larger.

Title: Pulsating combustion apparatus
Inventor: SAITOU TOSHIHIKO
IPC: F23C15/00
Filed: 1984-05-02
Abstract: PURPOSE:To obtain desirable pulsating frequency as well as to get a needed heating surface, by connecting a plurality of tail pipes of nearly the same length to a combustion chamber, and by setting pulsating frequency in those pipes corresponding to the length of one pipe. CONSTITUTION:Fuel gas and combustion air are fed into a mixing chamber 1 through feed pipes 2 and 3, respectively. Pulsating combustion starts in a combustion chamber 5 when mixed gas is ignited by an ignition plug 4. Explosion pressure accompanied with pulsating combustion is uniformly received by the downstream side of a combustion chamber 5 which is composed of a semi- spherical surface 5a. When four tail pipes 6... are used, for example, needed heat transfer area can be obtained with one-fourth length in comparison with the case when one tail pipe is used. When the former frequency was 25Hz, for instance, the latter becomes 50Hz. Thereby normal and stabilized pulsating combustion is taken place. Because a plurality of pipes in the nearly same length consist of tail pipes to be connected to the combustion chamber, the tail pipes can be designated in accordance with the need of heat transfer area, and desirable pulsating frequency can easily be obtained from those pipes. In addition, the size of the titled combustion apparatus can be miniaturized.

Inventor: MATSUMOTO YASUKAZU
IPC: H04B1/16
Filed: 1988-04-11
Abstract: PURPOSE:To improve the S/N of a sub broadcast without deteriorating the effect of a band pass filter by adding a difference signal of opposite phase to an FM composite signal comprising a main broadcast band and a sub broadcast band in a circuit extracting the sub broadcast so as to attenuate the difference signal of the FM multiplex signal. CONSTITUTION:A parallel circuit comprising a buffer 6 to adjust the level and a series circuit consisting of a multiplex circuit 7 and a balanced modulator 8 is formed between an RF IF detector 2 and a band pass filter 4 in a circuit extracting a sub broadcast. The multiplex circuit 7 extracts a difference signal (L-R) in opposite phase from a composite signal outputted from the RF IF detector 2, sends the result to the balanced modulator 8 and also extracts a subcarrier 38kHz and ends it to the balanced modulator 8, where the subcarrier 38kHz is modulated by the difference signal (L-R) in opposite phase and the result is fed to a composite signal subjected to level adjustment outputted from the buffer 8. As a result, the portion of the difference signal (L-R) of the sub channel in the composite signal inputted to the band pass filter 4 is sufficiently attenuated.

Title: Production of hardened piston ring made of steel
Inventor: SHIGEMOTO NOBUMASA
IPC: B21D53/84
Filed: 1979-07-13
Abstract: PURPOSE: To easily produce a hardened piston ring made of steel of high hardness under superior dimensional and shape accuracy by heating a wirelike or striplike steel material and forming the same to a piston ring shape, then immediately hardening and tempering, the same.  
     CONSTITUTION: A steel material being a blank material for piston rings is formed to a strip shape by drawing or roll forming and is heated to a temperature higher than the hardening temperature of this steel material. Next, it is put in a ring forming machine and is thereby formed to a piston ring shape. It is mechanically restrained and held in that state and is then quenched by oil, water, etc. whereby it is hardened. Since the material is formed to a piston ring shape and is quenched and hardened in that state without being removed from the device, it is hardened without  giving any change in its shape and after it has been subjected to necessary working,  it is fixed in jigs and is hardened. These obviate the production of any strain in  shape owing to hardening and tempering and enable the hardened piston ring of  steel of superior dimensional and shape accuracy to be produced.

Title: Electrolyte film for high molecular solid electrolyte fuel cell, manufacture thereof, and method for gas-sealing electrode unit of fuel cell with electrolyte film
Inventor: MURAYAMA KEIJI
IPC: H01M8/02
Filed: 1996-04-11
Abstract: PROBLEM TO BE SOLVED: To improve the battery characteristic, and prolong the lifettime of the battery by forming film thickness of a central part of inside, which corresponds to an electrode unit, thinner than a part, which does not correspond to the electrode unit. SOLUTION: Since film thickness of an electrolyte film 1 is formed so that film thickness of a central part of inside, which corresponds to an electrode unit, is formed thin, for example, at 50μm, battery characteristic is improved. Film thickness of a peripheral side part thereof, which does not correspond to the electrode unit, is formed at 150μm as an original film thickness. Consequently, since the peripheral side part 3 is formed thicker than the central part 2 of the inside, tensile strength is large, and it is hard to generate a breakdown near a packing, and lifetime is remarkably prolonged. Film thickness of the central part 2 can be reduced by performing O2 plasma treatment applied to this part in a low-vacuum condition.

IPC: B65D85/38
Filed: 1989-04-07
Abstract: PURPOSE:To permit an easy image processed and automated appearance inspection of an electronic part by making the color of non-pressure sensitive adhesive type darker than that of an exterior electrode of an electronic part. CONSTITUTION:The color of non-pressure sensitive adhesive tape 12 having an opening through which to view a pressure sensitive adhesive tape 13 attached to the other side of the tape 12 is made darker than that of an exterior electrode 4b of an electronic part. The dark color refers to the color indicating exactly a black point when the images of the tape 12 and the electronic part are processed into binary image. Since the color of the tape 12 is darker than that of the exterior electrode 4b of the electronic part, the electrode 4b is indicated as a white point and the tape 12 as a black point by processing their images. This permits the exterior electrode 4b to be accurately inspected.
