Inventor: MIYOSHI TAKASHI
IPC: G01B11/24
Filed: 1987-02-25
Abstract: A first convex lens (2), with a central aperture, having a focal point fl and a second convex lens (4), having a focal point f2, are arranged at an interval d (=fl+f2). A micro mirror (3) is provided, on the optical axis between the first and the second lenses (2, 4), to reflect the laser beam incident from an He-Ne gas laser (8) thereby emitting parallel beams, through the central aperture of the first lens (2), onto the surface (S) to be measured. The interval between the first lens (2) and the surface (S) is denoted as fl+zl. The interval between the second lens (4) and the image point (w), at which the image of the surface (S) is formed, is denoted as f2+z2. A position detector (l) of the image point, comprises a slit plate (5), a third convex lens (6), having a focal distance f3, and a CCD line sensor (7). The interval between the slit plate (5) and the sensor (7) is denoted as ℓ₀. The second and third lenses (4, 6) are so arranged that the focal points thereof coincide. The slit plate (5) is provided perpendicular to the optical axis, immediately before the third lens (6), and a pin hole is opened at an interval d₀ on either side of the optical axis. The line sensor (7) is positioned in parallel with the slit plate (5). The output of the sensor is input to the calculating means, to measure the position zl of the surface to be measured as explained below. The position z2 of the image point is obtained from the interval x of the incident positions of the beams incident onto the sensor, through the two pin holes. 
    x = {(f3²+f3z2-ℓ₀z2)d₀}/f3(f3+z2) 
The position zl of the surface to be measured is obtained from the position z2 of the image point, per the formula: 
    zl = z2/(f2/fl)²

Abstract: In a power semiconductor device according to the present invention, a sheet (11), formed of a soft metal such as Ag, is provided on that portion of a pressing control electrode (13a) which is brought into contact with an Aℓ gate electrode (1a) of a pellet (1). By means of this sheet (11), it is possible both to apply a strong pressing power to the Aℓ gate electrode (1a) and to reduce the contact resistance between the two electrodes (1a and 13a). Since an excessive amount of heat is not produced on account of the contact resistance, the semiconductor device can be protected against being damaged.

Abstract: A method of making and processing (machining) pref. thermoplastics panels having a protective foil on one or both faces is described. The protective foil is provided with rows of perforations just before it is applied to the thermoplastics panel or sheet, or continuous extrusion from which panels are subsequently to be cut. In the subsequent machining and processing of the panels, the protective foil can be stripped off locally along perforated lines, leaving the remainder of the panel properly protected. In a variant, an initially unperforated protective foil is locally perforated by a spiked roller or the like just before it is applied to the panel material. Pref. these perforations are applied to the side which will come into contact with the panel material.

Abstract: In a computer human interface an adjustable "window" (177, FIG 4) enables the user to view a portion of an abstract, device-independent "picture" description of information. More than one window can be opened at a time. Each window can be sized independently of another, regardless of the applications running on them. The human interface creates a separate "object" (represented by a process) for each active picture and for each active window. The pictures are completely independent of each other. Multiple pictures (170, 174) can be updated simultaneously, and windows can be moved around on the screen and their sizes changed without the involvement of other windows and/or pictures. Images, including windows, representing portions of any or all of the applications can be displayed and updated on the output device simultaneously and independently of one another. All human interface with the operating system is performed through virtual input/output devices (186, 187, FIG. 5), and the system can accept any form of real input or output devices.

Desirably at least four circuit layers are provided in two circuit layer pairs. Each pair comprises an insulating layer having opposing surfaces and having a circuit pattern on each of the opposing surfaces of the insulating layer.

     The connecting layer comprises an electrically insulating resin containing electrically conductive particles. The quantity of the particles is statistically selected so as to be sufficiently dispersed to prevent electrical conduction along the X and Y axes of the connecting layer and sufficiently concentrated and of a size to insure electrical contact through the Z-axis of the connecting layer between conductive portions of the circuit layers which are in contact with the connecting layer and directly opposite each other through the connecting layer. 
     The invention further includes a method for making the multilayer electronic circuit.
