Title: Projection copier of mask
Inventor: ERUNSUTO BUEE REEBATSUHA
IPC: G02B7/28
Filed: 1988-08-02
Abstract: PURPOSE: To keep the focal length const. which changes, depending on the refractive indexes of air and ambient medium on a projection object by adjusting the light frequency, depending on the detected refractive index of the ambient medium and utilizing the frequency dependence of the refractive index of the lens material. CONSTITUTION: An exposure aligner 1 has a means for adjusting the frequency- dependent refractive indexes of lenses 3a-3d, so that they may be const., relative to the air refractive index. This adjusting means is a rotary echelette grating 6, a controller 14 computes specified adjustable angle of this grating 6, and hence a control signal for providing specified frequency of the exposure light from known values about the variation of the lens refractive indexes and change of the air refractive index, depending on the frequency. Thus the focal length of the projection lens 3 is held const. at the wafer stepper region, without mechanical adjustments, regardless of the variation in the air refractive index due to the air pressure variation.

Inventor: IIJIMA TORU
IPC: B44C1/20
Filed: 1994-07-25
Abstract: PURPOSE:To prevent the generation of a wrinkle like damage on the surface of a molded product by forming empossed protruding parts to the surface of a laminate formed by successively laminating a synthetic resin surface layer having patterns on its surface, a flow adjusting layer and a synthetic resin flow layer without destructing the patterns of the surface layer.

Title: Wiring circuit device
Inventor: ISHIDA TETSURO
IPC: H05K1/18
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To surely execute soldering when mounting a fine-fabricated electronic component such as an integrated circuit, even if a lead is thinned. SOLUTION: A plurality of projecting and recessed parts, i.e., a number of dent groups 21, are formed in soldering parts for leads 3, in which integrated circuit elements such as an electronic part are thinned, that is, a bottom surface 22 in contact with a land 6. The bottom surface 22, on which the dent groups 21 are formed is positioned at the soldering parts of the land 6 in a circuit board and is soldered, such as reflow soldering. Namely, since the projecting and recessed parts are not formed by cutting the lead thin but they are rather formed by forming dents and rimples, solid soldering can be executed surely without reducing the strength of the lead 3. Furthermore, a comparatively heavy electronic component such as a capacitor can be mounted at a sufficient strength.

Title: Viterbi equalizer and transmission data system judging method
Inventor: KUBO HIROTSUGU
IPC: H03M13/41
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To stably output a precise judging value even when a specific tap coefficient in an actual transmission path becomes small by deciding whether to output a bias value by a bias value preparing means in accordance with the pattern of transmission path characteristic inputted to a replica generating means. SOLUTION: A bias value preparing circuit 14 receives estimated transmission characteristic of one period before from a storing circuit and in a prescribed case, prepares a bias value for adding a branch metric. In the circuit 14, a threshold judging circuit receives transmission path from the storing circuit, and fixes a tape coefficient smaller than a previously decided threshold to be 0. By fixing data on specific transmission path characteristic to be 0 like this, transmission path characteristic threshold-judged by a bias value deciding circuit is inputted to add a bias value when a leading tap coefficient is 0, for example, and to avoid adding the bias value except for it.

Title: Processing method for crystal of compound semiconductor
Inventor: NISHIZAWA JIYUNICHI
IPC: H01L21/265
Filed: 1981-12-01
Abstract: PURPOSE:To minimize the deviation in a crystal from the stoichiometrical composition, by performing a process of raising temperature and a process of lowering temperature while controlling the vapor pressure of at least one high vapor pressure component element of the component elements of the crystal. CONSTITUTION:When a GaAs crystal is subjected to heat treatment under as As pressure, it is subjected thereto for 10hr at the heat treatment temperature of 1250 deg.K. The optimum As pressure at this temperature corresponds to a point 31 on a line 10, equaling an atmospheric pressure of 0.2. The temperature of an As chamber on the low-temperature side for realizing this As pressure is equivalent to a temperature at a point 30 whereat a line drawn from the point 31 in parallel to the axis of a bscissa intersects a line 11. That is, the temperature of the As chamber needs to be set so that T=833 deg.K. Therefore, it is essential to raise the temperature of the As chamber as 21-23-30 so as to correspond to 22- 24-31 on the line 10 when the temperature of a GaAs crystal chamber is raised up to 31. When the temperature is lowered after the completion of heat treatment, it is also indispensable to taken a process reverse to the above mentioned process for controlling the deviation from the stoichiometrical composition in a complete sense.
