IPC: H01L21/027
Filed: 1988-07-18
Abstract: PURPOSE:To obtain highly accurate leveling mechanism which can perform exposure without reducing throughput by a method wherein leveling is carried out by the three-point driving method. CONSTITUTION:A driving device (20a, etc.) which aligns a wafer W surface with respect to a leveling reference working face 3f determined by a distortion reference point (OA, etc.) as a specified tilting reference face of a leveling stage 3, a focus detecting device 11 which detects Z-directional deviation in position of the leveling reference working face 3f and the wafer W surface and a main control device 15 which calculates driving amount of three pivots (25, etc.) from detected signals of the focus detecting device 11 and controls the driving device (20a, etc.) so that the leveling reference working face 3f and the wafer W surface are approximately aligned are provided. Therefore, on the basis of the detected signals of the focus detecting device, three pivots 25 are driven in the Z direction by the same amount, the leveling reference working face 3f and the wafer center surface are approximately aligned, and then leveling is performed. This decreases horizontal deviation caused along with leveling to a level lower than the allowable value.

Title: Method for constituting low-band digital filter
Inventor: FUKUDA MITSUYOSHI
IPC: H03H17/04
Filed: 1987-07-17
Abstract: PURPOSE:To improve the filter characteristic of a low-band digital filter in a low band, by improving the multiplying accuracy without increasing the number of bits for multiplication when this low-band digital filter is realized by means of a digital signal processor. CONSTITUTION:In case of a low-frequency band, constants C1, C2, C3... of the product sum calculation Y1=C1.Xi+C2.Xi-1+C3.Xi-2... for realizing a digital filter are divided in the form of alpha+beta.delta (where, the alpha is an integer and the betais the value obtained when the decimal part is divided by a constant delta(delta<<1) which is common to each constant) and the constant delta is multiplied after product and sum calculation is applied on each constant beta with respect to inputted data. Then this low-band digital filter is realized by adding and subtracting the results of the product sum calculation performed on each constant alpha and inputted data to and from the multiplied results. Since the decimal part of each constant is expressed as the product of the significant figure beta and common constant delta which is very small of <1, such as beta.delta, the beta is expressed by a limited less bit number, for example, 16 bits and the product sum calculation with data can be accurately carried out.

Abstract: PURPOSE: To keep the air cool in summer and prevent heat from escaping within a tin-roofed house in winter by a method wherein a heat collector utilizing a rugged roof surface is used to absorb solar energy, whereas heated air is collected by taking advantage of the movement of air caused by a temperature difference.  
     CONSTITUTION: Heat insulative material 3 is placed on the whole surface of a roof on plywood 2 attached to a rafter 1 and a galvanized iron plate 4 is used to form a plane and further a black corrugated heat absorbing plate 5 is attached onto the place in order to form an air storage chamber 6 between the iron plate 4 and the heat absorbing plate 5. The heat collecting pipes 9 are arranged at the same pitch intervals as those of the heat absorbing plates 5 above the ridge wood 7 so as to collect heat utilizing gas transfer caused by the temperature difference of the air in the chamber 6. Simultaneously, the heat is sent to a heat exchanger 12 within a tank 13 by connecting the pipes 9 to a pipe 10 to use the heat for hot water supply and space heating. By so doing, problems deriving from hot weather in summertime can be solved and the heat is utilizable for thawing snow, space heating and the like in the cold season by reversely operating a pump 11.

Title: Sample holder for electron beam exposure device
Inventor: MAKITA FUTOSHI
IPC: H01J37/20
Filed: 1988-07-18
Abstract: PURPOSE:To prevent ground failure by installing an elastic plate which eliminates an electron beam sensitive resist applied to the surface of a sample in a shape like a belt and a ground needle which contacts with the surface of a sample where the resist is scraped off due to an electric short developed in a member. CONSTITUTION:An elastic plate is bent upward along the slope of its point when it hits against the side of a mask 2 that is being inserted, and steps on the surface of a mask 2. And it scrapes off a layer of electron beam sensitive resist 4 to make a metal film 5 to be exposured in a shape like a belt. As a result a ground needle 3 steps on the surface of the mask 2 such that it persures after the elastic plate 8. As the ground needle 3 comes into contact with the metal film 5 exposed in a shape like a belt because the layer of electron beam sensitive resist 4 is scraped off by the elastic plate 8, it becomes unnecessary for a ground needle to scrape off the layer of the resist 4 as before so that failure can be prevented. Moreover, as the elastic plate 8 itself has a function of grounding, it can take the place of the ground needle 3.
