Filed: 1990-07-19
Abstract: PURPOSE:To flatten a surface enough and to prevent increases in contact resistance with efficient deposits of SOG in a side recess of the first wiring by spin coating with SOG after an SiO2 side spacer is provided on a side face of the first wiring. CONSTITUTION:An SiO2 film formed on a first aluminum wiring 2 is etched back. As a result, an SiO2 film remains on a side face of the wiring 2 and is used as a side spacer 3-1. Thus, the top face of the wiring is exposed, while the side face is coated with the spacer 3-1. Next, SOG(Spin-On-Glass) is applied by a spin coater. In this case, the side face of the wiring 2 is coated with the SiO2 spacer 3-1 which is well-wettable with SOG, and the top face of the wiring shows an exposure of aluminum which is poorer-wettable with SOG than SiO2. Therefore, SOG penetrates deeply into a recess on the side of the wiring 2 so as to flatten enough and prevent increases in contact resistance.

Title: Image forming device
Inventor: MAEKAWA KAZUNOBU
IPC: G03G15/01
Filed: 1997-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent an image carrier from being re-transferred and to prevent a transferred image on a transfer sheet from being damaged by providing a mode for electrifying the image area brought into contact again with the image carrier in the nontransfer state to the same polarity as the normal polarity of toner after transfer is completed in forming multiple images. SOLUTION: When the image area is split in the moving direction of a transfer sheet and the same transfer sheet is repeatedly used for a transfer to form multiple images for the split image areas, this image forming device is set to the mode that the transferred image area is brought into contact again with a photoreceptor drum 206 in the nontransfer state. The output of a transfer charger 205 is made weak when the image forming area of the copy image passes through the photoreceptor drum 206 in the nontransfer state. Even when the electric resistance of the transfer sheet and the charged quantity of the toner are reduced due to the humidity conditioning in the high-humidity environment, the toner can be attracted and kept on the transfer sheet, and the toner can be prevented from being transferred again to the photoreceptor drum 206.

Filed: 1989-07-26
Abstract: PURPOSE:To reduce inclusions and to make a molten steel high-cleanliness by holding oxidizing slag on a molten metal until decarburizing treatment is finished and reducing the oxidizing slag simultaneously with the initiation of deoxidation at the time of secondary refining. CONSTITUTION:A molten metal tapped into a ladle is subjected to decarburizing treatment by means of a vacuum degassing apparatus and successively to deoxidation treatment.

Title: Exposure device for color copying device
Inventor: SUZUKI MINORU
IPC: G03G15/01
Filed: 1986-08-18
Abstract: PURPOSE:To obviate a color decomposing filter, to suppress the drop of optical energy and to attain exposure based upon lamps with small capacity by forming a color separating optical image directly by the lamps with different wavelengths. CONSTITUTION:When an original platen 5 is moved from the shown state in the right direction, an original is illuminated by any one, e.g. 16A, of exposure lamps 16A, 16B, 16C in an exposure device 16, and reflected light, i.e. an optical image, from the original is exposed to a photosensitive belt 8 through a convergent optical transmitter array 6 and a filter 7. Fluorescent lamps, cold cathode tubes or the like for emitting light with different wavelengths are selected as the exposure lamps 16A-16C and reflected optical images from the original are obtained as optical images corresponding to respective wavelength components, i.e. color separating optical images, so that a color separating filter can be omitted. Thereby optical energy loss due to the color decomposing filter can be suppressed, and therefore it is unnecessary to set up the electric capacity of the lamps 16A-16C themselves to a comparatively large level.

Title: Vertically magnetized recording medium
Inventor: SUGIMOTO MAMORU
IPC: G11B5/64
Filed: 1982-11-01
Abstract: PURPOSE:To improve an output power and resolution significantly by a method wherein one or more of Zr, Nb, Mo, Tc, Rh and Pd are added to Co-Ru and crystalline particles are magnetically separated to each other. CONSTITUTION:When a vertical anisotropic magnetic field Hk of a film of Co- Ru vertically magnetized recording medium is heightened, its vertical coercive force Hc is also increased. Although high Hk is desirable for a vertical recording medium, when Hc becomes too large, it is necessary to apply large current to a magnetizing head made of a material such as ferrite, Permalloy, Sendust or amorphous soft magnetic substance in order to make it saturated and the problems occur that even if saturated recording can be done, it is difficult to eliminate it or that overwrite characteristics are deteriorated. On the other hand, if a writing current and overwrite characteristics are improved, Hk becomes small and reversed magnetization in high density recording is not sharp so that the recording density characteristics are deteriorated. By adding one or more of zirconium, niobium, molybdenum, technetium, rhodium and palladium as the third element, these problems are solved.

Title: Electronic musical instrument
Inventor: SUZUKI SATOSHI
IPC: G10H1/30
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to generate continuous musical tones at different time intervals by one time of operation of an operating element by providing an electronic musical instrument with a control means for controlling the time intervals for generation of plural musical tone signals so as to vary these signals. SOLUTION: The contents of the hold mode flag (HLD) in a RAM 10 are inverted every time a hold mode switch 4c is pushed. The control to form the percussion instrument tones and effect tones is changed over corresponding to the contents of this flag. Namely, the upper two bits of the percussion effect number(PEN) information for assigning the kinds of tones are made ineffective in the case of HLD=0. In such a case, the musical tone signals are so formed that the effect tones are attenuated according to a prescribed curve after attack in the same manner as for the percussion instrument tones. The upper two bits of the PEN information are made effective in the case of HLD=1. The contents of the wait time table before the next attack attain the value meeting the random number generated at that time if the second bit of the PEN information is 1.  Thereby, the musical tones having fluctuations, like those of murmuring of rivers, are produced.

Abstract: PURPOSE:To numerically and objectively judge the air vent effect of a plug-up type cap by detecting the pressure of air transmitted from the upper part of the rigid cylindrical side wall of the cap having the same shape as the mouth section of a container through a pressure transmitting passage formed through the inside of the side wall. CONSTITUTION:A measuring tool is constituted of a ring-shaped base 30 and a cylindrical side wall 31 integrally formed with the base 30. The upper part is formed into the same shape as that of the mouth section of such a container as the bottle, etc., because a cap is actually put on the part.
