Title: Electromagnetic driving system
Inventor: SAKAI KOUJI
IPC: H04R9/04
Filed: 1980-02-26
Abstract: PURPOSE: To realize an electromagnetic driving and electromagnetic generating system which has improved a reproducing sound and distortion of a generating waveform, by providing a negating coil for magnetic flux generation in order to prevent a part of magnetic flux generated by a current flowing through a  moving coil varies a magnetic line of force inside of a magnetic pole.  
     CONSTITUTION: A cross magnetic field 10 is generated newly by a current flowing through a moving coil 8 of a dynamic loudspeaker, and since it lies at right angles to a magnetic field generated by a magnet 4, in a place near an air gap 3, it causes no problem, but it varies the number of magnetic fluxes in the inside of a center magnetic pole 1 due to the same direction, as a result of which induced electromotive force due to said variation is generated in the moving coil 8, thus a current waveform is distorted, and it causes distortion of a reproduced sound. According to said system, the influence of the crossing magnetic field 10 is reduced and the distortion of a reproduced sound is improved by providing a compensating coil 11 on the center magnetic pole 1 and connecting a direction 12 of a magnetic field generated by said coil in the direction for negating a magnetic flux generated by the coil 8. This system is applicable to the electromagnetic driving and electromagnetic generating system having the same structure.

Title: Method for forming photoresist pattern
Inventor: KOIZUMI TAICHI
IPC: G03F7/38
Filed: 1993-02-12
Abstract: PURPOSE:To restrain a photoresist pattern from varying in line width due to a standing wave effect when the pattern is formed on a substrate such as a semiconductor wafer or the like. CONSTITUTION:Photoresist material is applied onto a substrate 1 such as a semiconductor wafer or the like to form a photoresist film 2, and a first light exposure process is carried out by the use of a prescribed light source and a mask 4. Then, the photoresist film 2 is thermally treated on a hot plate 6 to be reduced by a prescribed value in thickness. Thereafter, a second light exposure process is carried out by the use of the same light, source and the mask as the first process. At this point, the thickness change of the photoresist film is set so as to enable the nodes and antinodes of light standing waves generated at the first and the second light exposure process to deviate from each other in position. By this setup, a resist pattern can be lessened in dispersion of line width by a resultant effect of standing waves. Especially, when a photoresist film is changed in thickness by an odd-numbered times as much as 1/4 of the wavelength of a light source in the film, a resist pattern can be most lessened in dispersion of line width.

Abstract: PURPOSE: To facilitate the recognition of the pointing part of a visual information instructor at the time of using a noncontact projecting and pointing device. CONSTITUTION: Spot light source emitting parts 12 and linear light source emitting parts 13 are lined up and arranged on the same straight line. A power source is supplied to a lighting delay processing section 14 when the visual information instructor pushes a lighting instruction section 16. The lighting delay processing section 14 supplies the power sources to the respective light emitting parts 12, 13 in such a manner that the spot light sources are made to emit light and are then put out and in succession the linear light sources are made to emit light with a time lag and are then put out. An optical illusion of motion takes place in a visual information receiver when the images of the spot light sources and linear light sources emitting light in such a manner are projected. The linear light sources appear as if these light sources emit light by moving toward the direction further from the spot light sources from the direction near the spot light sources emitted light previously. The images of the linear light sources are apparently dynamically displayed by utilizing the such optical illusion of the visual information receiver, by which the function to recognize the pointing part is enhanced.
