Title: Aligner
Inventor: NAKAMURA KYOJI
IPC: H01L21/027
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To improve exposure accuracy by reducing the influences of vibration of an illumination optical system during exposure on a light exposure main part. SOLUTION: An illumination optical system IOP is separated into a first optical system part IOP1, including a blade which is movable during light exposure operation and a second optical system part IOP2 which does not include a movable part above the movable blade movable during the light exposing operation, the second optical system part IOP2 is installed on a main body column 14, forming a light exposure main body, and the first optical system part is installed separated from the light exposure main body. Thus even if the movable blade moves by a large extent during the light exposure, this involves generation of vibration in the first system part IOP1 and residual vibration remains during the light exposure and the vibration will have no adverse effect on the second optical system part and the light exposure main body provided therewith.  Accordingly the influences of the vibration of the illumination optical system on the light exposure main body during the light exposure can be reduced, thus resulting in improved exposure accuracy.

IPC: B22C9/06
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To make it possible to effectively control a mold temperature by forming a metal porous layer having a specific porosity and pore size of hot isotropic pressure sintered material having a plurality of types of metal particles including different thermal conductivities uniformly dispersively mixed in a surface layer area of a cavity side, and connecting a heat exchange medium flow tube. SOLUTION: The fine pores of a metal porous layer 11 for forming the inner surface of the cavity of a mold 10 are used as heat exchange medium channels. Thus, the porosity of the layer 11 is set to 7 to 50% to provide efficient heat exchange with remarkably large contact surface area with the medium per unit volume of the mold 10. The mechanical strength is reduced, and the pore size is so limited to 500μm or less as not to lose the suitability as a mold material. The layer 11 is formed as mixed phase sintered material having a plurality of types of metal particles including different thermal conductivities uniformly dispersively mixed, and heat resistance and cooling properties necessary for the mold 10 can be incorporated as the plurality of types of mixing effects.

Title: Ground fault detector circuit for electric car
Inventor: SUGIURA TOSHIHIKO
IPC: G01R27/18
Filed: 1994-08-30
Abstract: PURPOSE: To detect a line-to-ground fault not only of the bus-line of a d.c. power supply but also the inside of the d.c. power supply and an a.c. feeder or the inside of a.c. motor with inexpensive constitution. CONSTITUTION: A rectangular wave pulse of a duty factor of 50% is generated by an oscillator 11, and the signal is outputted through an impedance converter 12 and connected to a positive bus-line through a detection resistor 13 and coupling capacitor 10A The peak value of the rectangular wave pulse which appears at a connection point P is not reduced under the normal condition and therefore, a comparator 21 outputs the rectangular wave pulse of a duty factor of 50%.  When a line-to-ground fault is generated in an a.c. motor 3, the peak value of the rectangular wave pulse is divided by the detection resistor 13 and a line-to-ground fault resistor 31 to be made lower than a reference voltage V1 obtained by voltage divider resistors 22, 23 and therefore, the output of the comparator 21 becomes a constant voltage value of a duty factor of 100%, thereby being able to detect a line-to-ground fault.

Title: Magnetic transferring method and magnetic recording method for digital image signal
Inventor: NARUSE KOJI
IPC: G11B5/64
Filed: 1992-07-31
Abstract: PURPOSE:To reduce the error rate by using a copied and mother magnetic recording media respectively having prescribed characteristics and superimposing the recording media upon another so that the inclined directions of the magnetic domain columns of their magnetic layers can become opposite to each other, and then, transferring signals by impressing an external bias magnetic field from a prescribed direction. CONSTITUTION:A magnetic layer composed of a magnetic metallic thin film is formed on a nonmagnetic substrate. A copied magnetic recording medium C in which the angle thetaCE from the intrasurface direction of the axis of easy magnetization of its magnetic layer is set at 70 deg.+20 deg. and a mother magnetic recording medium M in which the angle thetaME from the intrasurface direction of the axis of easy magnetization is set at 20 deg.+15 deg. are used. While the media C and M are superimposed upon another so that the inclined directions of the magnetic domain columns CLC and CLM of their magnetic layers can become opposite to each other, an external bias magnetic field HB is impressed from the direction which is 110 deg.+15 deg. from the intrasurface direction of the medium M. Under such condition, the recorded magnetization of the medium M is transferred to the medium C. Therefore, the error rate can be reduced, since a sufficient reproduced output can be obtained even when the shortest recording wavelength is about 0.5mum, and recording and reproduction can be performed for a long time.

Title: Film image input device
Inventor: AISAKA SHIGENORI
IPC: G03B27/46
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To automatically output a normal image despite of whether a developed still photographic film is a negative film or a positive film. SOLUTION: A negative/positive discrimination part 322 inputs a voltage signal corresponding to the quantity of light transmitted through a film 124 from a light receiving means 321 and discriminates whether the film 124 is the negative film or the positive film, based on the level of that input voltage. Corresponding to the discriminated result at the negative/positive discrimination part 322, an image signal processing circuit 323 performs negative or positive image processing to the image signal inputted from a CCD 116. Namely, in the case of the negative film, negative image processing is performed to the inputted image signal but in the case of the positive film, positive image processing is performed to the inputted image signal and afterwards, the processed image signal is outputted onto a video monitor 119.  Thus, the normal image is automatically reproduced on the video monitor 119 in spite of whether the film 124 under using is the negative film or the positive film.

Abstract: PURPOSE:To form an electrode wiring layer excellent in a step coverage in a contact hole provided to an insulating film of a multilayer interconnection by a method wherein a first electrode wiring layer formed of aluminum is subjected to a heat treatment, where melted aluminum is made to ascend up in the contact hole through the fluidity and the expansion of the melted first electrode wiring layer and the stress occurred in a second insulating film provided to the first electrode wiring layer. CONSTITUTION:A first electrode wiring layer 3 of an aluminum wiring layer is provided to a first insulating film 2, for instance, a silicon nitride film formed on a silicon substrate 1 and a second insulating film 4 is formed thereon. Next, the silicon substrate 1 is heated, where the aluminum wiring layer is made to melt to expand, aluminum ascends up in a contact hole 4a through the pressure impressed through the difference in the thermal expansion coefficient between the silicon nitride film and aluminum, and an aspect ratio is made to be small. Even when the silicon substrate decreases in temperature, aluminum in the contact hole 4a is kept in the same condition as it is because aluminum is very small in volume as compared with the first electrode wiring layer 3. Therefore, the face of a formed second electrode wiring layer 5 is made to be flat, wherefore a flat passivation film 6 is able to be formed even in the position of the contact hole 4a.
