Title: Road condition detecting device
Inventor: NAKAMURA HIROYUKI
IPC: G01S15/50
Filed: 1990-08-27
Abstract: PURPOSE:To enable a road condition to be accurately detected by extracting a signal having a frequency shifted to such an extent as corresponding to a Doppler shift computed from the frequency of an ultrasonic wave transmitted to the road on the basis of a ground speed. CONSTITUTION:A transmitter 21 sends an ultrasonic wave having a frequency of a f0 to a road on the basis of an electrical signal having a frequency of f0 generated with an ultrasonic wave supply source 10. A receiver 22 is so positioned as to be capable of receiving irregular reflection waves giving an effective Doppler shift, among reflection waves generated on the road. The received ultrasonic waves are converted into electrical signals and amplified in a preamp circuit 31. In a tracking filter 32, only signals having a frequency of f0 + DELTAf (Doppler shift) are extracted from pure irregular reflection waves from the road. The aforesaid DELTAf is computed on the basis of a vehicle speed V detected with a speed sensor 23. The noise component of the signal is eliminated with a low pass filter 35 via an AM detection circuit 34, thereby obtaining a signal D accurately detecting a road condition.

Abstract: PURPOSE:To prepare high purity disilane with high yield basing on the amt. of raw material in a process for prepd. disilane and trisilane from monosilane by an electric discharge method by carrying out the reaction under a positive low pressure in the presence of an inert gas by using unreacted monosilane freed of higher silane such as tetrasilane in circulation. CONSTITUTION:Disilane (Si2H6) and trisilane (Si3H8) are prepd. from monosilane (SiH4) by an electric discharge method by introducing gaseous SiH4 3 into a reactor 11 provided with a discharge tube 1 after evacuating the reaction apparatus to high degree of vacuum by a vacuum pump 2. Harmful higher silanes than tetrasilane are separated by condensing in the first and second trap 4, 5 cooled to -130 deg.C with liq. N2. The pressure of the gas dropped by said separation is recovered by the addn. of N2 6 as inert gas and the reaction is caused under a positive low pressure (1-2atm) to transform unreacted SiH4 to Si2H6 and Si3H8 in the reactor. Thus, Si2H6 and Si3H8 having high purity are prepd. from SiH4 as raw material with high yield.
