Title: Acoustic matching layer, ultrasonic wave transmitter/receiver and flow measuring apparatus of fluid having the same
Inventor: BETSUSOU DAISUKE
IPC: H04R17/00
Filed: 2004-03-18
Abstract: <P>PROBLEM TO BE SOLVED: To alleviate the distortion and warpage of the acoustic matching layer of a porous body made of the dry gel of an inorganic oxide, to improve flatness and to further improve the accuracies of an ultrasonic transmitter/receiver using the acoustic matching layer and a flow measuring apparatus.  <P>SOLUTION: The acoustic matching layer 1 includes a fine structure 2 and the porous body 3 of a disk shape having the shape of a diameter of 10.8 mm, and a thickness of 200 to 500 μm. As the porous body 3, for example, the dry gel of the inorganic oxide is used. The dry gel of the inorganic oxide is made of the porous material having an air gap of nano-size (nano is 10<SP>-9</SP>m), and its density is about 0.2 to 0.5 g/cm<SP>3</SP>. Since the inorganic dry gel has a small density, its strength is weak. Since a shrinkage arises in a forming process, the distortion arises to cause the generation of a density distribution. However, when the fine structure is mixed, the absolute amount of the dry gel of the inorganic oxide is reduced and the shrinkage is suppressed by the strong bond with the fine structure, and the distortion is alleviated.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Inventor: NAKAMURA MITSUO
IPC: H04B1/7097
Filed: 2004-03-25
Abstract: <P>PROBLEM TO BE SOLVED: To improve an S/N in spread spectrum communication.  <P>SOLUTION: In a transmitter, a spreading code having a chip width which is natural-number times of one cycle of a cyclic signal is generated, and the cyclic signal is multiplied with the spreading code for transmitting a resultant spreading signal. In a receiver, the reception signal is made synchronous with the spreading code, and the reception signal is multiplied with the spreading code. Since the chip width of the spreading code is natural-number times of one cycle of an original cyclic signal, if the chip rate of the spreading code is sufficiently high relative to change of the original cyclic signal, multiplying results of the reception signal and the spreading code have almost the same waveforms (35A<SB>1</SB>-35A<SB>m</SB>) in view of time interval corresponding to the chip width of the spreading code within the range of one code length of the spreading code. By extracting the multiplying results at the time interval and adding them, only a signal component among the multiplying results is emphasized with a noise component being relatively suppressed.  <P>COPYRIGHT: (C)2006,JPO&NCIPI

Title: Synchronous motor device
Inventor: KIMURA JUN
IPC: H02P6/08
Filed: 2004-03-31
Abstract: <P>PROBLEM TO BE SOLVED: To provide a synchronous motor device which can synchronously control a synchronous motor without using an encoder.  <P>SOLUTION: When power supply is turned on, this device energizes only the coils 22U and 22U' of U phases and magnetically attracts rotor teeth 24 by stator teeth 23 which generate electromagnetic force for U phases. After passage of the time when the shake of a rotor 11 settles, this energizes all phases, with the energization of U phase ON. Hereby, this can surely counterpose the rotor teeth 24 to the stator teeth 23 where the coils 22U and 22U' of U phases are mounted. When rotating the rotor 11, this switches the energization of each phase in order with open control where the synchronization does not step out until the control value comes to a specified value while counting the number of times of energization of each phase, thereby rotating the output shaft to the target rotational position. By the above, this can synchronously control the motor while abolishing an encoder.  <P>COPYRIGHT: (C)2006,JPO&NCIPI
