Title: Ultrasonic wave converter
Inventor: TSUJI YORIICHI
IPC: H04R17/00
Filed: 1989-09-28
Abstract: PURPOSE:To simplify the structure, to make the size small and to reduce the weight of the converter light by forming a vibrator only with a piezoelectric thin film and an electrode without use of a beam made of silicon or silicon oxide. CONSTITUTION:A vibrator 1 consists of a piezoelectric thin film 3 comprising 2-layer structure of a low resistance layer 2a whose electric resistance is small and a high resistance layer 2b whose electric resistance is large, on which 1st and 2nd electrode layers 4, 5 are formed, and the one end of the film 3 is supported to a substrate 6 as a cunti-lever. When an AC voltage is applied between upper and lower electrode layers 4, 5 of the piezoelectric thin film 3, since the electric field is concentrated onto only the high resistance layer 2b, expansion/contraction is caused in the high resistance layer, while no expansion/contraction is caused in the low resistance layer 2a, the vibrator 1 having a beam shape as a whole is vibrated vertically and then an ultrasonic wave is sent. Thus, the ultrasonic wave converter of simple structure, high performance and small size and light weight is obtained.

Title: Inductor element
Inventor: KOBAYASHI HIROSHI
IPC: H01F17/04
Filed: 1988-10-08
Abstract: PURPOSE:To obtain an inductor element which is excellent in inductance characteristics and is capable of miniaturization by constituting it out of a conductor whose surface is covered with soft magnetic amorphous metal. CONSTITUTION:This is constituted of a conductor whose surface is covered with soft magnetic amorphous metal. Any conductor will do so long as the electric resistance is small, and it is to be desired that the soft magnetic metal to cover the surface of the conductor should contain amorphous alloy or Co. In particular, for Co-Fe alloy in composition of Co/Fe=94/6, since the value of magnetostriction becomes zero, the one whose atom number ratio of Co to Fe is 90% or more is preferable. To cover the conductor surface with soft magnetic amorphous metal, wet plating method is preferable because it is excellent in productivity. Hereby, a noise filter can be constituted simply by covering the foot 2 of a semiconductor element main body 1 with soft magnetic amorphous metal 4, and miniaturization of the element, facilitation of manufacturing and cost down can be realized.

For purging the trapped sulfur, the trap 32 is heated up to about 650 deg.C. The purging operation takes about three to ten minutes at this temperature. In a lean mode, nitrogen oxides and sulfur oxides are accumulated in the trap for nitrogen oxide. After absorbing almost whole in the trap 32, the purging operation is performed.  Via an operation for fuel injection amount, an exothermic reaction providing sufficient temperature rising occurs in the trap 32.
