Title: Pll circuit
Inventor: OKADA KAZUO
IPC: H03L7/06
Filed: 1987-01-29
Abstract: PURPOSE:To stably operate a PLL circuit with a high frequency by modulating a signal with the frequency signal from the D/A converter, which performs D/A conversion of the output frequency from a digital waveform generating circuit, to generate an output frequency signal. CONSTITUTION:One part of the signal oscillated by the first highly stable oscillation source 11 is inputted to one multiplier 12, and another part is inputted to a multiplier 14 through a 90 deg. phase shifter 13, and outputs of multipliers 12 and 14 are subjected to subtraction by an adder 15. The frequency signal oscillated by an oscillation source 17 which is highly stable similarly to the oscillation source 11 is converted to frequency signals different in phase by 90 deg. by a logic circuit 18, and they are converted to analog signals by D/A converters 19 and 20 and are inputted as modulating signals to multipliers 12 and 14 through filters 21 and 22. Consequently, the frequency of an output Vout of the adder 15 can be changed in a wide range if the clock frequency of the oscillation source 17 is converted to another frequency by the logic circuit 18 in accordance with the output of a digital filter 4. Thus, a stable output signal is obtained because highly stable oscillation sources 11 and 17 are used.

IPC: G01N23/22
Filed: 1989-01-30
Abstract: PURPOSE:To make structure analysis by the secondary ion mass analysis of a thin org. film sample by irradiating the sample surface with an H<+> ion as a primary ion and thereby accelerating the formation of a compd. ion which is the secondary ion generated from the sample surface. CONSTITUTION:After the assay sample is mounted on a holder, the apparatus is subjected to evacuation. An acidic gas which is the supply gas of the H<+> ion is introduced into the chamber of an ion gun and thereafter, an electric discharge is induced. The energy and ion intensity of this H<+> ion are adjusted and the sample is irradiated with the ion. The generated secondary ion is detected by a mass spectrograph. Then, the vapor deposited film of malachite green lactone is analyzed by using Ar<+> and H<+> respectively as the primary ion. The sample is irradiated with the H<+> as the primary ion in such a manner to accelerate the formation of the compd. ion which is the secondary ion. The structure analysis by the secondary ion mass analysis of the thin org. film sample is thus executed.

Title: Projection aligner
Inventor: KAMIYA SABURO
IPC: G03F7/20
Filed: 1989-01-30
Abstract: PURPOSE:To increase a focusing margin by a method wherein an optical-axis direction of an object to be exposed is positioned in such a way that an average deviation between the surface of an exposure region directly under a projection optical system and an image- formation plane of the projection optical system becomes minimum. CONSTITUTION:A height distribution of the surface of an unexposed exposure region is sampled and measured at definite intervals by using a shape sensor 1; it is stored in a memory 13. An interpolation computation is executed by means of a CPU 12 on the basis of a height distribution data which has been stored in the memory 13; a height in a part which has not been measured is estimated. Then, a height of the surface of the exposure region after an inclination of a wafer 5 has been adjusted is computed by means of the CPU 12 in such a way that the surface of the exposure region is nearly parallel with an image-formation plane of a projection lens 3. Then, a difference between a reference point P of the surface of the exposure region and a point corresponding to the image-formation plane in the case where an average deviation between the surface of the exposure region and the image- formation plane of the projection lens becomes minimum is computed as a Z-correction amount (DELTAZc). The Z-correction amount is corrected with reference to a value detected by means of a Z-sensor 4; it is judged at a controller 14 on the basis of a corrected value whether the height of the exposure surface is proper or not. Thereby, it is possible to project and transcribe a clear image even when a warp or an uneven part exists on the surface of the exposure region.

Accordingly, the beam 9 after the passing of the second scanner is set parallel to the beam before the passing of the first scanner.

Title: Floor covering element * assemblage and production
Inventor: FURITSUTSU NOAKU
IPC: E01C5/00
Filed: 1980-02-15
Abstract: A ground covering element adapted for positioning adjacent another ground covering element. The outer contour of the ground covering element forms projections and recesses about its entire periphery, has corner projections which form the vertices of a rectangle and line portions all of which are oblique to the sides of the rectangle connecting the corner projections. At least two of the line portions connecting each of the vertices are of equal length and the remaining line portions have lengths which are integer multiples of the lengths of the at least two line portions of equal length. A plurality of irregular spaced polygons project from the top surface to form raised portions, the majority of the polygons differing in shape from each other. The edges of the raised portions are straight and separated from each other by dummy gaps having widths which vary linearly along the entire length thereof and from the periphery of the ground covering element by marginal dummy gaps. The edge of each raised portion adjacent the periphery of the element substantially follows the contour thereof and has a distance therefrom such that the average distance between the edge of the raised portion adjacent the periphery and the contour is approximately equal to the average width of the dummy gaps between the raised portions. Sand is used to fill the space between the adjacent ground covering elements thereby effectively concealing this space from view.

Title: Conductivity-modulation type mosfet
Inventor: WATANABE KIMINORI
IPC: H01L29/78
Filed: 1989-01-27
Abstract: PURPOSE:To increase a latchup current and to reduce a cost by providing a second conductivity type low impurity concentration diffused layer diffused on the surface of a wafer of a range from a drain isolating layer to a source layer. CONSTITUTION:A second conductivity type low impurity concentration diffused layer 15 diffused on the surface of a wafer from a drain isolating layer 5 of the second conductive type to a source layer 4 is provided. Since the impurity diffused layer has a concentration gradient in a depthwise direction different from an epitaxial layer, if a total impurity amount is constant, the concentration can be enhanced in the vicinity of the surface as compared with that of the epitaxial layer. Accordingly, when the surface concentration is the same as that of a prior art, the inner impurity concentration of a first conductivity type base layer 3 can be enhanced. Thus, a latchup current can be raised without increasing a threshold value. Since an epitaxial wafer is not employed, its manufacturing cost is reduced.
