Abstract: PURPOSE:To obtain a sufficiently large isolation resistance between elements by a method wherein two or more ion implantation operations are executed under individually different conditions and a surface density of implanted ions is set at 10<12>cm<-2> or higher near an interface between a substrate and a semiconductor layer. CONSTITUTION:Two or more ion implantation operations are executed, under individually different conditions, between integrated semiconductor elements formed on a semiconductor layer which has been grown epitaxially on a substrate 1. A surface density of implanted ions is set at 10<12>cm<-2> near an interface 10 between the substrate 1 and the semiconductor layer. In this case, it is suitable that the implanted ions are formed of one out of an inert element, oxygen, nitrogen, boron and an element constituting the semiconductor elements or a combination of them.

Title: Apparatus for controlling micro-rotation
Inventor: NISHIMURA KAORU
IPC: G03F7/20
Filed: 1983-12-30
Abstract: PURPOSE:To micro-rotate a rotary disk by providing first and second electrostriction devices, the first device being constantly contacted with the outer periphery of the disk and by inclining while simultaneously extending the second electrostriction device and vice versa. CONSTITUTION:When no voltage is applied either of electrostriction devices 4 and 22, the end face of the device 4 is contacted with a disk 1 at a point P1. When a voltage is applied to the device 22 to extend the same, the device 4 is inclined and the contact point is changed to a point P2. In this state, when a voltage is applied to the device 4 to extend the same, the contacted distance between 26 and 28 of the device 4 is changed to d+DELTAd, where DELTAd is several mum. Then the application voltage to the device 22 is stopped to return the device 4 to its original position and to return the contact point from P2 to P1. Since the device is still extended, however, it is contacted with the contact point 27 of the disk at a contact point 31 which is present on the right side of the contact point 26 by DELTAd. When the application of voltage to the device 4 is stopped to contract the same after the device 22 is sufficiently returned to its original position, the disk is rotated clockwise minutely by DELTAd. According to this construction, the micro-rotation of the disk can be driven by accurately controlling the extension and contraction of the electrostriction device, with a high precision of 0.1sec/pulse and without any backlash.

Abstract: PURPOSE:To manufacture a superbly reliable manifold by affixing a bonding agent on a bonding surface of a cover block, coating said layer with a sheet of breathing structure all over, and providing additionally a bonded surface of a main block on the sheet and bonding thereon. CONSTITUTION:A bonding agent 3 is applied on a bonding surface 2 of a cover block 1, and said bonding agent 3 layer is coated with a breathing sheet 4.
