IPC: H01L21/20
Filed: 1980-04-11
Abstract: PURPOSE:To contrive the improvement of the life time of a minority carrier and the leakage current characteristics of a P-N junction by forming a semiconductor film gradually changing from amorphous into crystalline on an insulating substrate. CONSTITUTION:A laser beam 5 is focused at a point on the film surface 3 of an amorphous film 2 formed on an insulating substrate 1 through a slit 6 and a focusing lens 8 and the focus 4 of the beam 5 is scanned on the whole surface of the film surface 3 by moving the substrate 1 as shown in arrows. Next, the inside surface is scanned by the focus 4 by the focus depth of the lens 8 by moving the focus depth of the lens 8 downward and by narrowing the gap of the slit 6. In the above operation, the film 2 changes from the film 3 into a semiconductor film gradually changing from poly crystalline into amorphous toward the direction proceeding to the substrate 1. In this formation, lots of stress such as temperature stress or the like are appreciably mitigated comparing with crystalline substance. Therefore, a crystalline section can expect good crystallization and a deterioration in the characteristics of the element formed in the crystalline section can be prevented.

Title: Digital camera
Inventor: SUGIMOTO KAZUHIKO
IPC: G03B13/36
Filed: 1998-03-02
Abstract: PROBLEM TO BE SOLVED: To precisely control focusing even under low illuminance by setting the detecting cycle of an AF evaluation value to be longer than the term of one frame when the illuminance of an object is low. SOLUTION: The object is pre-exposed. Based on the luminance evaluation value of the object obtained by the pre-exposure of the object, an optimum exposure term is calculated by a microcomputer 40. When the optimum exposure term is over the term of three frames, the luminance of the object is judged to be insufficient and the detecting cycle of the AF evaluation value is set to be the term of two frames by the microcomputer 40. That means, the object is exposed extending over the term of two frames at respective lens positions and the contrast component of the object is integrated extending over the term of two frames when the focusing is controlled. Thus, the AF evaluation value is obtained for every two frames.

Title: Transformer coupled secondary dc power supply
Inventor: KUSAKA TOYOYASU
IPC: H02M3/28
Filed: 1993-03-11
Abstract: PURPOSE:To prevent overvoltage in an astable power supply system by performing switching control from a switching element connected with the intermediate tap of primary winding to a second switching element connected with the terminal tap of primary winding having increased number of turns. CONSTITUTION:Number of turns of the primary winding L11 of a transformer 20 is increased over that of a winding NP11 required for normal control and a switching element (SW) 12 connected with an intermediate tap Tm is controlled. When a stable power supply system 32 is loaded heavily while an astable power supply system 31 is loaded lightly and the voltage of the astable power supply system 31 exceeds a set level, an overvoltage detecting circuit 45 detects an overvoltage. Consequently, a control circuit 50 controls an SW15 in place of the SW12. In other words, since impedance of the primary winding L11 varies, power energy to be fed to the astable power supply system 31 having a constant number of turns NS1 is reduced.

Then, the electron beam 36 is deflected 7 again to form a microbeam near the second reference point K' in order to scan the mark 35, and the central coordinates thereof are obtained. Differences DELTAx and DELTAy between both the central coordinates are obtained in the CPU21 and stored 27. When an oblique pattern is lithographed, the pattern is read out 24 to deflect 7 the electron beam, which is moreover deflected 11 by adding 29 the read-out position- designating signals to the deflection correcting amounts DELTAx and DELTAy so that the beam having a section of the oblique pattern is deflected to a given position. Thereby, the position of the oblique pattern is designated by using the reference point K of a rectangular pattern, so that lithography is accurately performed.
