Abstract: PROBLEM TO BE SOLVED: To increase the maximum change angles of front and rear wheels by providing a first tie-rod connected to one end of a link attached to a differential case of a first drive axle in such a manner that it can turn freely in the horizontal direction and an outer drive steering mechanism and a second tie-rod connected W to the other end of the link and the other outer drive steering mechanism. SOLUTION: The direction of front wheels is changed at two steps by an inner drive steering mechanism and an outer drive steering mechanism 7. First, a lock condition of hydraulic cylinders 13A, 13A is released. Then, the inner drive steering mechanism is turned in the horizontal direction by the hydraulic cylinders 13A, 13A by turning a steering wheel. A front wheel side case of a second front wheel drive axle 6 is turned and the front wheels turn by using this inner drive steering mechanism as a shaft. The inner drive steering mechanism turns by the maximum angle, stops, and enters a fixed condition. Then, a steering arm on front wheel side 12 on one side is turned. The turn of the steering arm on front wheel side 12 on one side is transmitted to the outer drive steering mechanism 7, and the front wheels turn furthermore.

Abstract: PURPOSE: To efficiently recover unreacted allyl alcohol by carrying out the azeotropic distillation and separation of water in a low-boiling fraction separated after copolymerizing the allyl alcohol with styrene in the presence of H2 O2 as an initiator using diallyl ether as an entrainer. CONSTITUTION: The azeotropic distillation and separation of water in a low- boiling fraction obtained by separation with an evaporator, etc., after copolymerizing allyl alcohol (A) with styrene (S) in the presence of H2 O2 as an initiator are carried out using diallyl ether (D) as an entrainer to recover the unreacted A. For example, the low-boiling fraction is charged into a recovering column 1-1 and the D is then charged from the column top to perform the azeotropic distillation. The three-component azeotropic distillation of water in the charging liquid with the A and D is carried out to condense the distillate in a condenser 2-2 at the column top. The condensate is collected in a separating tank 3-3 thereunder and the aqueous layer in the separated lower layer of the condensate is taken out of the system.  The upper layer containing the D is returned to the column top of the recovering column 1-1 to recover the dehydrated A from the column bottom.

Title: Vibrating body driving device and powder supply device
Inventor: MURAI KATSUMI
IPC: G05D19/02
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To make a resonance frequency applied to a vibrating body follow up the actual resonance frequency of the vibrating body when the actual resonance frequency varies by feeding a residual frequency generated by the residual vibration of the vibrating body back to a PLL control means. SOLUTION: When a duty ratio control circuit 12 does not apply a resonance frequency to a driving circuit 13, an ultrasonic motor 15 slightly vibrates owing to residual vibration caused by inertia. This residual vibration generates an electromotive force. A resistance 14 is provided so as to accelerate a flow of a current generated by this electromotive force and a sufficient current is supplied to a current monitor 15 and then shifted (delayed) in phase and converted into a voltage at the same time. Then the generated voltage is fed as actual resonance frequency information back to a PLL control circuit 11 through a zero-cross comparator 17. Consequently, the actual resonance frequency of the residual vibration can accurately be obtained from the electromotive force, and a sufficient signal can be obtained as the feedback signal of the PLL control circuit 11.
