Patent JP-H1117642-A (JP)
Title: Receiver
Inventor: SATO KAZUMI
IPC: H04J11/00
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To obtain stable reception characteristics at all times, even in the case that a propagation environment has changed extensively by measuring the delay time of delay waves generated by multipath and changing the band width of a band width variable filter which corresponds to the measured delay time. SOLUTION: In a time response measurement part 7, from the time response of a transmission line, the delay time of the delay waves by the multipath is measured. A band width setting part 8 sets the band width of a band width variable filter 9 to an appropriate value, by using the delay time output of the time response measurement part 7. Then, the delay time of the delay waves generated by the multipath is measured, and the band width of the band width variable filter 9 is changed corresponding to the measured delay time. Thus, even in the case that the propagation environment is has changed extensively in the band width variable filter 9, a transmission line response inputted from a transmission line response calculation part 5 can be filtered in an appropriate band at all times and the stable reception characteristics are obtained.

Title: Spike pin
Inventor: WATANABE MAKOTO
IPC: B60C11/16
Filed: 1986-07-21
Abstract: PURPOSE:To prevent road face damage by providing a cover capable of elastic deformation outside a spike shank and positioning the top of the cover on the top face of a spike shank as shooting, in a spike pin of spike type for vehicle. CONSTITUTION:At running on i not-frozen road face, a shooting 7 is projected from a tip 4 on the summit face of a shank 3 and the tip 4 doesn't contact with the road face. At this time, the friction coefficient between the shooting and the road face is large and the sideward slipping of the shooting 7 doesn't occur. And on the frozen road face, the friction coefficient between the shooting 7 and the snow/ice becomes small and the shooting 7 causes the sideward slipping and the shooting 7 shifts outward along the top end face 9 of the shank 3 and enters a groove 15. Hereby, the tip 4 contacts with the road face to function as a spike. By this constitution, road face damage can be prevented.

Title: Ultrasonic flaw detector
Inventor: UCHIDA KUNIHARU
IPC: G01N29/44
Filed: 1982-09-30
Abstract: PURPOSE:To improve the detection sensitivity of a defect at long distance and to perform flaw detection in a short time by summing up signals which exceed a threshold level at a waveform adder in a summing memory, and performing signal processing regarding only signals which exceed the threshold level in a gate which specifies a specific propagation direction. CONSTITUTION:An vibrator 104i is controlled by a computer 110 to generates an ultrasonic wave in a propagation direction theta1. The receive signal waveform of the vibrator 104i is a receive signal waveform 132i delayed by the difference in distance from the defect and added by the waveform adder 122. When the sum waveform in the gate exceeds the threshold level, the adder 122 outputs a detection signal and at this time, the time from the oscillation to detection signal output, i.e. path time Ti is calculated. Then, this Ti is inputted to a signal processing circuit 128 to calculate defect depth Zi by arithmetics as mentioned above. Further, said operations are performed while the ultrasonic-wave propagation detection theta1 is changed to complete the flaw detection within its necessary range.

Abstract: PURPOSE:To increase breakdown strength at a time when laminating an insulating film by forming a polycrystalline silicon film onto the insulating film in the main surface of a semiconductor substrate at a specific reaction temperature and bringing the crystal grain size of the polycrystalline silicon film to 100Angstrom  or less. CONSTITUTION:When silicon is attached onto an insulating film 52 in a semiconductor substrate 51 at a reaction temperature of 400 deg.C or 600 deg.C, crystallization hardly progresses, and an amorphous silicon film 53 is shaped.

When the reaction temperature is elevated to 600 deg.C or 800 deg.C and a polycrystalline silicon film 54 is formed, grain size is shaped to 100Angstrom  or less. Traps on the grain interface are removed and phosphorus is diffused uniformly when phosphorus is diffused thermally to the polycrystalline silicon film 54, and local sections where field concentration is liable to be generated such as the irregularities of a crystal are also decreased largely in the interface of an insulating film 55 even when laminating the insulating film 55, thus increasing breakdown strength.
