Title: Ultrasonic motor drive
Inventor: FUNAKUBO TOMOKI
IPC: G05D3/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic motor drive in which the frequency can be tracked easily even when a so-called hard system piezoelectric element is employed for driving an ultrasonic oscillator while stabilizing the motor characteristics.

Title: Fuse structure and production thereof
Inventor: PREIN FRANK
IPC: H01L21/82
Filed: 1999-11-04
Abstract: PROBLEM TO BE SOLVED: To enhance fuse cutting window through laser by adding a substance being etched more selectively than a gate gap layer to a dielectric layer and an interlayer dielectric layer. SOLUTION: A dielectric layer 130 and an interlayer dielectric layer 128 are patterned to form a hole 134 on a gate structure 116. The hole 134 is formed by etching the interlayer dielectric layer 128 selectively to a nitride. The hole 134 penetrates the dielectric layer 130 and the interlayer dielectric layer 128 but only a relatively thin gap cap 122 is removed by etching. In this method, a gate structure 116 has a thin dielectric layer which includes only the gap cap 122 and a smaller quantity of dielectric is present on a fuse. Since the time for applying laser energy is shortened by reducing the quantity of dielectric on the fuse, quantity of energy being applied to the periphery of the fuse can be reduced.

Title: Optical interference type shape measuring instrument
Inventor: FUJIWARA NORIAKI
IPC: A61H23/00
Filed: 1987-12-15
Abstract: PURPOSE:To improve the in-plane resolution running along the surface of an object to be measured by displacing a sample table on which the object to be measured has been placed, in a minuter distance than a resolution of an interference fringe observing means. CONSTITUTION:A sample table 21 is displaced in the X direction by applying a prescribed voltage to a first piezo-element 22. This displacement quantity is a minute value obtained by dividing a resolution 1.65mum of an image pickup device 7 being an interference fringe measuring means by a positive integer. In this state, a measurement by a fringe scanning method is repeated, while displacing stepwise the sample table 21 until the displacement quantity in the X direction becomes 1.65mum, the position in the X-direction of the sample table 21 is returned to its original position. With regard to the Y direction, as well, the same measurement is executed. Subsequently, based on a variation of a shape caused by the displacement in the X direction and the Y direction, an uneven state on the surface of an object 4 to be measured is calculated by an interpolating method, and displayed on a screen of an arithmetic unit 7. In such a way, the in-lane shape running along the surface of the object 4 can be measured precisely.
