Title: Circuit design of semiconductor device and program storage medium
Inventor: YAMADA AKIKO
IPC: G03F1/32
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence by a side lobe pattern by preparing the prohibition rule for eliminating a circuit pattern including a fundamental pattern having a tolerance lower than a preliminary set reference value from the subject of design based on a common lithography process tolerance and then designing a circuit based on the rule. SOLUTION: The overlap between a calculated first lithography process tolerance (S5a) and a calculated second lithography process tolerance (S5b) is calculated as a common lithography process tolerance (S6). Next, it is judged whether the common lithography process tolerance thus calculated satisfies a set reference value (S3) or not (S7). As a result, fundamental patterns which satisfy the reference value are extracted to prepare a rule table (S8). When a rule table which can satisfy the reference value cannot be prepared (S7 No), it is clear that the extracted group of fundamental patterns (S1) cannot be formed properly on a semiconductor substrate. In this case, a different group of fundamental patterns is extracted and the same procedure is repeated.

Title: Instant film of peel-apart system
Inventor: SETO TAKASHI
IPC: G03C7/00
Filed: 1988-03-23
Abstract: PURPOSE:To reduce the cost of the instant film by sticking plural negative sheets at prescribed intervals to long-sized paper broader than the negative sheets, thereby constituting the instant film. CONSTITUTION:A negative film is cut to a sheet shape (negative sheet 11) having nearly the same are (=image forming area) as the area of a positive sheet. These sheets are stuck only at the front end (part B) at the specified intervals onto the long-sized roll paper 12 which is broader than the negative sheets 11 and is known as a carrier sheet by positioning the latent image forming surface to the outer side. Such paper is wound to a roll shape and the roll is housed into a light shielding housing container. The paper is drawn out at every image formation and is cut in the position of an alternate long and short dash line by a cutter to the sheet shape. The sticking of the negative sheets 11 is capable of preventing the wrinkling, etc., of the sheets 11 generated by a difference in the winding diameter by the respective thicknesses when the sheets are wound together with the roll paper 12 to the roll shape. The area for which about 1.46 times the transfer image area is heretofore required is, therefore, decreased to about the same area. The cost of the film is thereby reduced.

Title: Magnetic scale device
Inventor: OOKUBO HIROYUKI
IPC: G01D5/20
Filed: 1979-05-30
Abstract: PURPOSE: To accelerate the shorter wavelength and higher density of the magnetic grating along with the focusing effect of signal magnetic fluxes, obtain higher resolution and increase the degree of freedom of magnetic scale constitution by using a multiple-gap magnetic yoke.  
     CONSTITUTION: Magnetic gratings of intrinsic wavelength λ have been recorded and formed in a magnetic scale 11 and a multiple-gap magnetic yoke 13 is movably disposed to the magnetic grating face 12 of the scale 11 in opposing contact therewith. The yoke 13 is formed by arraying high-magnetic permeability portions 14 and the portions 15 of a low magnetic permeability nearly equal to the gap alternately at λ/2 period in opposition to the magnetic gratings. In such a position relation between the yoke 13 and scale 11 that the leakage magnetic field HS of the top surface 16 of the yoke 13 becomes strongest, the magnetic flux flows in the arrow direction. When the yoke 13 moves in the X direction with respect to the scale 11, the magnitude and direction of the leakage magnetic field on the top surface of the yoke 13 changes in correspondence to the wavelength of the magnetic gratings and this enables the detection of scale signals and permits the measurement of relative movement amounts.

IPC: H02K21/16
Filed: 1994-03-11
Abstract: PURPOSE:To improve control characteristic and efficiency by approximating an inverse electromotive force generated in a coil to a sine wave in an external magnetic field type synchronous motor. CONSTITUTION:In a synchronous 3-phase motor having the even number of magnetic pole pairs, permanent magnets 51 to 54 are not arranged in the positions having equal interval but in the positions which are deviated forward and backward from each other by an electric angle of 30 degrees. Namely, electric angle of one magnetic pole pair is set to 330 degrees, while electric angle of the other pair is set to 390 degrees. As a result, an electromotive force generated at the coil of phase U, for example, is deviated in the phase forward and backward in one coil and the other coil and its composite voltage is not generated in the rectangular shape and has a part which is changing step by step at the rising and falling edges. As a result, an electromotive force generated in the coil of each phase, that is, a terminal voltage between phases is approximated to a sine wave to improve control characteristic and efficiency of a synchronous type 3-phase motor.
