摘要： PURPOSE:To generate an optional simulated sound in quick response to the driving state of a vehicle by providing a parameter storage means which can be accessed at random instantaneously. CONSTITUTION:This device is equipped with a control means 5 which grasps the driving state detected by a driving state detecting means 4 and indicates one group of composite parameters among plural groups of composite parameters stored in a parameter storage means 6 to a composing means 7 and speakers 301 - 303 which reproduce a simulated sound with a signal of composite sound from the composing means 7. Therefore, one group of composite parameters corresponding to the driving state is read out from the parameter storage means 5 which can be accessed at random instantaneously and those composite parameters are used to synthesize the simulated sound. Consequently, simulated sounds are reproduced in quick response to momentary variation of the driving state.

摘要： PURPOSE:To make it possible to detect a minute gap with a simple constitution by arranging many minute-gap detecting pieces on a frame body having the shape along the periphery of a member to be inspected in an array pattern. CONSTITUTION:An ultrasonic-wave inspecting sound source part 13 which has at least one ultrasonic-wave piezoelectric transducer 24 as a pseudo point sound source and has the approximately uniform radiation characteristic is arranged in a tightly sealed space which is sealed with a door (an object to be inspected) 41. The ultrasonic waves which are transmitted into the tightly sealed space from the sound source part leaks to the outside through a minute gap when there is the minute gap at a part which is sealed with the door 41 of an automobile (an object to be inspected) 12. A plurality of minute-gap detecting pieces 43 of an ultrasonic wave sensor are provided in an ultrasonic-wave leakage detecting part 14 facing the sound source part along the sealing part at the outside convert the leaking ultrasonic waves into the detected signal. The distribution of the minute gaps generated in the peripheral part of the automobile 12 can be positively detected based on the signal.

摘要： PURPOSE:To make it possible to sufficiently correct the dynamic imbalance of a tire in a state mounted to an actual car within a short time, by allowing the vibration characteristic of the tire in a state mounted on the actual car on the basis of the dynamic imbalance of the tire to be approximate to linearily. CONSTITUTION:A piston rod 9 is held between small caliber semi-cylindrical parts 3 by opposing split pieces 2, 2 to each other and a cylinder 10 is held between large caliber semi-cylindrical parts 4. A bolt 11 is inserted in a bolt hole 6 and tightened to integrated the piston rod 9 and the cylinder 10 and a shock absorber 8 is fixed to bring the characteristic of a suspension supporting a tire to non-linearity near to a linear characteristics. In this state, the tire is rotated to measure a vibration level and a correction wt. is mounted so as to bring the vibration level A to zero. Thereafter, the vibration level is measured again and, by repeatedly performing this operation, residual imbalance quantity can be allowed to approach zero as near as possible.
