Title: Surface acoustic wave device
Inventor: MATSUI ATSUSHI
IPC: H03H9/05
Filed: 1984-03-27
Abstract: PURPOSE:To incorporate a capacitor into a surface acoustic wave device in order to decrease the number of external parts, by providing counter electrodes holding a zinc oxide thin film and over the lead-out electrodes. CONSTITUTION:Counter electrodes 81 and 82 hold a zinc oxide thin film 7 and set on comb-shaped electrodes 61 and 62. While counter electrodes 101 and 102 are provided on lead-out electrodes 91 and 92 respectively. Thus the electrostatic capacity is produced between electrodes 91 and 92 as well as 101 and 102 respectively. Therefore connecting the electrode 101 of the electrode 91 to an input/output terminal 121 is equivalent to capacitors connected in series. Furthermore connecting electrodes 92 and 102 to an input/output terminal 122 and an earth terminal respectively is equal to capacitors connected in parallel. Thus it is possible to incorporate a capacitor into a surface acoustic wave device. This contributes to reduction of the number of external parts.

Abstract: PURPOSE:To make it possible to improve work efficiency and to enhance attachment accuracy in a magnetic head grinding device by holding a head base with an elastic force relative to a main body of a jig. CONSTITUTION:A main body of a rotary jig 2, when a force is applied on a pressure plate 16 by means of a moving means, moves resisting a spring 19 tensely installed between a pin 17 of a horizontal table 11 and a pin 18 of the pressure plate 16. Under this condition, when a head base 21 which is a workpiece is fed by means of a feeding means onto the horizontal table 11, is placed on the horizontal table 11, and the external force which has been applied on the pressure plate 16 is removed, a pressure contact piece 16' of the pressure plate 16 presses the head base against one of L-shaped walls and holds by means of an energizing force of the spring 19.

Title: Method and instrument for measuring depth of minute groove
Inventor: TAKADA KAZUMASA
IPC: G01B11/22
Filed: 1986-03-17
Abstract: PURPOSE:To measure in a moment the depth of a minute groove by converting the depth of the minute groove into the distance between mirrors generating two interference peaks in the interference intensity and measuring it and taking an S/N large. CONSTITUTION:Light emitted from a white light source 5 via a lens 8, etc., is separated into two light waves of the reflected light A and the transmitted light B via a beam splitter 9. The reflected light A is reflected totally with a total reflection mirror 11 and transmitted through the splitter 9. On the other hand, the transmitted light B is reflected on an Si substrate 10 to be measured and afterward, reflected on the splitter 9 and joined the previous reflected light A. At this time, since the light source 5 is white, the transmission of the light is regarded as a pulse. Then, there is a delay of 2d in space and 2d/c (c is light velocity and d is depth of the groove) in time between the reflected light pulse 21 from the Si surface and the reflected light pulse 22 from the Si groove base in the reflection on the substrate 10 having the minute groove for forming a capacitor. Accordingly, in case the mirror 11 is moved at a constant speed, the two interference intensity peaks are generated and the depth of the minute groove of the substrate 10 is measured from the interval.
