Title: Magnetostrictive speaker driver
Inventor: SHOMURA ATARU
IPC: H01L41/12
Filed: 1999-05-28
Abstract: PROBLEM TO BE SOLVED: To constitute the whole speaker as a slim type speaker by driving a speaker diaphragm by using a magnetostrictive(MS) element. SOLUTION: The MS speaker driver is constituted so that a pair of winding coils 15a, 15b are wound around the outer periphery of the MS element 14 formed by molding an MS material to be magnetostrictively deformed in the direction almost rectangular to a magnetic field applying direction upon receiving an external magnetic field like a thin plate, fixing both the end parts and setting up the center part as a driving point of the speaker diaphragm 12 through the driving point.  Since the MS element 14 expressing an MS horizontal effect to be extended in the direction almost rectangular to the magnetic field applying direction and the diaphragm 12 are mutually connected on the driving point, a plane speaker 11 can be constituted by opposing the element 14 close to the rear side of the diaphragm 12, the thickness of the speaker along the vibration direction of the diaphragm 12 can be sufficiently reduced and extremely thin constitution can be obtained.

Title: Fuel supply system of engine with supercharger
Inventor: TADOKORO ASAO
IPC: F02D41/34
Filed: 1982-08-30
Abstract: PURPOSE:To maintain a high charging efficiency of an engine and to prevent knocking thereof by providing a fuel supply controller which increases the fuel to air ratio obtained by a supplementary fuel supply means and reduces the same ratio obtained by a main fuel supply means in the case of high load and low speed running of an engine. CONSTITUTION:A main fuel supply means and a supplementary fuel supply means are disposed in a main intake passage and a supplementary intake passage, respectively. With an engine running under a high load, a supercharging range discriminating device 102 generates a high level output so that an output S11 is produced at a supplementary fuel injection pulse width generating circuit 107. With the engine running in a middle and low speed range, the pulse width of the output of the circuit 107 is elongated by the output signal S10 from a revolution range discriminating device 114. Consequently, the quantity of fuel which is supplied from an injector 80 is increased, whereas the quantity of fuel from an injector 54 is reduced as much as the increment. Thus a high charging efficiency may be maintained and knocking can be prevented effectively.
