Abstract: PURPOSE:To enable to surely realize a junction type FET having the prescribed pinch- off voltage Vp value by a method wherein the presumption of the pinch-off voltage Vp value can be accurately performed properly in the manufacturing process of the junction type FET. CONSTITUTION:A window 5 is protrudedly provided on a part of an Si3N4 layer 4 on a region 2, which is to finally become the gate region of the FET to be used as a circuit element on the region 2, and at the same time, a pair of windows 6a and 6b are protrudedly provided on a region 3. P type impurities, Zn, for example, are diffused on each region 2 and 3 through these window 5, 6a and 6b, and a P type gate region 5 and a pair of regions 8a and 8b for characteristic detection are respectively formed. The characteristics through this gate regionm 5 are presumptively detected indirectly. This detection is performed by a way that electromagnetic needles consisting of Cu, etc., respectively, that is, probes 9a and 9b, are set up in contact respectively on the regions 8a and 8b for characteristic detection and the impedance between both probes is measured. By this measurement, the pinch-off voltage of the FET to be used as a circuit element becomes known. On the basis of this result, additional diffusions are performed on the regions 7, 8a and 8b at need in a depth, by which the purposive pinch-off voltage Vp value of the FET can be obtained, and the depth is set at the prescribed depth.

Title: Can
Inventor: NAKANO HIROKAZU
IPC: B65D17/32
Filed: 1989-08-21
Abstract: PURPOSE:To obtain a can with a stay-on-tab which does not come off the can and whose strength can be kept as same as a pull-tab can even with non- carbonic drink put in wherein inner pressure is low by a method wherein the tab is connected to a main body at one position and can be rotated with respect to the connection part as the center in a can. CONSTITUTION:A tab 3 is fixed to a main body 1 and a lid 2 wherein when the lid 2 is to be opened, the tab is raised in a direction (a) first and after a part of the lid 2 and the main body 1 are separated, the tab 3 is pulled along a direction (b) and rotated so that the lie 2 can be separated from the main body 1. Since the lid 2 and the tab 3 are shifted from a mouth, they may not disturb drinking. In addition, since the lid 2 is covered by the tab 3, injuring by the cut of the lid 2 can be prevented. Since the tab is constituted to be connected with the lid, force can be efficiently transmitted as force for pulling the lid from the main body so that the strength of a stay-on-tab can can be approximately equal to that of a pull-tab can even with non-carbonic drink put in whose inner pressure is low.

SOLUTION: The carrier gas from a gas cylinder 20 passes through a mass flow rate controller 24, then through the precursor material in a foam box 22, picks up the precursor material and flows from a head gap 23. The dilute stream of the gas carried to the mass flow rate controller 24 by a parallel circuit is mixed with the gaseous stream and is introduced to the reactor 10 where the thin films are grown on a substrate 30. At this time, the gaseous mixture is passed through an acoustic cell 40 near the inlet port 16 of the reactor 10 and the compsn. is calculated. As a result, the compsn. of the gaseous mixture may be controlled. Simultaneously, the compsn. of the gas to be discharged is calculated by an acoustic cell 50 near the outlet port 18 of the reactor 10 and the reaction part ratio is determined from the compsns. of both gases.
