Abstract: PURPOSE:To prevent generations of cavitation and choking sound by a method wherein the land section of a sleeve valve member, rotatable relatively with respect to the rotary valve member, is provided with a long groove and a communicating hole to secure sufficiently the flow path area of a supplying port for pressure fluid. CONSTITUTION:When a steering torque is applied to a steering shaft to twist a torsion bar 25 and rotate the rotary valve member 22 relatively with respect to the sleeve valve member 21, the opening area of a choking section 50 between a supplying hole 29 and one of distributing holes 32 is increased while the opening area of the choking section 51 between the supplying hole 29 and the other distributing hole 31 is decreased.

Filed: 1980-08-14
Abstract: PURPOSE:To increase the response speed of switching at frequency dividing ratio switching, by forming pulses having T times the frequency of input pulse frequency, frequency-dividing this as the input clock pulse, and frequency-dividing the output to 1/T. CONSTITUTION:Frequency of an input pulse CP is multiplied by T at a double frequency circuit 11 to form an input clock pulse CK and this is inputted to a binary counter 12. A frequency dividing data set to a latch circuit 13 is decoded at a decoder 14 and the decoded frequency dividing value is inputted to a coincidence detection circuit 15. The circuit 15 compares the frequency dividing value with the count value from the counter 12, the coincidence of both the data is detected to output the coincidence detection pulse to a 1/T frequency-dividing circuit 16, and the counter 12 is reset with the coincidence detection pulse and a frequency dividing ratio data is fetched to the circuit 13. Since the input pulse is frequency-divided into 1/T at the circuit 16 and makes output, when the frequency dividing ratio is switched, the switching response time can be reduced to 1/T.

IPC: G10K11/16
Filed: 1995-05-10
Abstract: PURPOSE: To provide a soundproof material which can efficiently shield and absorb its noise even if a noise of a different frequency level is generated and whose weight is not increased. CONSTITUTION: A soundproof material 1 having three sheets 2, 3 and 4 and air layers 5, 6 and 7, is installed on a surface on the engine room side of a hood panel P. Through holes 2a, 3a and 4a are respectively formed at prescribed intervlas in the respective sheets 2 to 4. Energy of a noise is attenuated and absorbed mainly by the so-called resonance effect when its wave passes through the through holes 2a to 4a and is propagated to the air layers 5 to 7 or the like. A wave of the noise strikes on the sheets 2 to 4, and its sheets 2 to 4 themselves move slowly. Its energy is converted into vibration, heat or the like, and energy possessed by the noise is attenuated.  Particularly, since the plural sheets 2 to 4 and the plural air layers 5 to 7 are arranged, individual sound absorbing characteristics can be made different from each other, and resonance type sound absorption is attained.
