Title: Digital filter
Inventor: SHIRAISHI MIKIO
IPC: H03H17/02
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To detect an overflow for multiple bits of two bits or more, and also completely prevent generation of overflow oscillation. SOLUTION: In operation of a digital filter, the overflow for multiple bits of two bits or more can be detected by arranging an overflow detector for detecting an overflow which generates data exceeding a fixed bit length. A clipping circuit is provided which fixes an output to a positive maximum value when a positive overflow has been detected by the overflow detector and to a negative maximum value of magnitude when a negative overflow has been detected. Accordingly, the generation of the overflow oscillation can be completely prevented.

Title: Porous rubber stamping body
Inventor: MURAI HIDEKI
IPC: H01J37/305
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To provide a porous rubber stamping body, the cell interconnecting properties of which is improved under the state that the uniformity of cell is kept as it is and the hardness of which can be lowered without lowering its strength. SOLUTION: A master batch, which is prepared by kneading at least an unvulcanized rubber, water-soluble particles, a vulcanizer, a filler and a vulcanized porous rubber ground to 2.0 mm or less, is vulcanized and then the water- soluble particles are removed from the resultant vulcanized master batch in order to obtain a porous rubber stamping body having open cells. Further, by compounding 0.1 to 30 wt.% of the vulcanized porous rubber to the total amount of the master batch, a porous rubber stamping body having open cells is also obtained.

Title: Wafer processing apparatus
Inventor: YUYA YUKINORI
IPC: H01L21/677
Filed: 2000-09-28
Abstract: PROBLEM TO BE SOLVED: To shorten the transfer time of a wafer, while preventing positional displacement of the wafer. SOLUTION: A wafer transfer robot 50 for transferring a wafer in a CVD system is controlled by a modified trapezoidal curve 63, which has sections 63b of constant acceleration other than zero-point 0 and each curved points ta. Since maximum acceleration factor αmax can be restrained to be low, the displacement of the wafer at the maximum acceleration is prevented, and since positive and negative turning point of acceleration factor αis set to pass the zero-point 0 at an slanting side 63a of the modified trapezoidal curve 63, generation of impact force which displaces the wafer is prevented at this point.  Since wafer transfer time per distance is reduced, while preventing wafer displacement, the total processing time for the CVD system can be reduced, and the throughput of the system is increased, and the generation of particles due to the displacement of the wafer is prevented.

IPC: G10L21/043
Filed: 2000-10-13
Abstract: PROBLEM TO BE SOLVED: To search for present broadcasting by reproducing the sound easy to listen without sense of incongruity in an on-vehicle audio apparatus having a function capable of rehearing a broadcast sound. SOLUTION: A stream memory 120 stores an audio signal sent from a receiver 110 via an analog-to-digital converter 130 and a signal discriminator 140 only for recent five min. In this case, the discriminator 140 discriminate whether the audio signal is a monaural or stereo signals, and transmits an address of the monaural signal to a controller 150A. The controller 150A designates a start of reproducing from a time point of 10 s before the time falling in a state in which a broadcast is hard to listen when a driver becomes easy to listen. The controller 150A designates that only the stereo signals are reproduced at an equal speed for initial two min and thereafter omitted. Thus, since the present broadcast can be searched for, the driver can listen to the reproduced sound without sense of incongruity and does not miss the information.
