Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a processing method of an Si wafer wherein etchant which prevents irregularity on an etching wall surface and an etching bottom and produces a desired smooth etching configuration stably in anisotropic etching processing of silicon is used. SOLUTION: A silicon oxide film 11 is provided to an Si wafer 10 of (100) surface azimuth whose both sides are polished, resist 23 is applied to the both sides and a resist pattern 12 is formed by using a photomask. After the Si wafer 10 is immersed in buffered hydrofluoric acid solution and a silicon oxide film 11 in a specified part alone is removed, the resist 23 is peeled by immersing into a mixture of heated sulfuric acid and hydrogen peroxide water. The Si wafer 10 is immersed in two or more alkaline water solutions (one thereof is inorganic or organic hydroxide, etc.) and an etching wall surface and an etching bottom surface are formed smoothly by applying the fact that surfaces reacting fastest to the etching effect work in the different way.

Title: Ink jet printer
Inventor: SUZUKI SHOGO
IPC: B41J2/045
Filed: 1997-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an ink jet printer for forming an optimum image corresponding to a screen pattern. SOLUTION: When a screen pattern is a dither type, a piezoelectric element is expanded at a timing J6 that a pressure wave P in an ink storage chamber becomes maximum to maximize an ink discharging speed to enhance an ink shooting accuracy. When the pattern is an error diffusion type, the element is expanded at a timing J8 that the wave P is lowered from the maximum to suppress the ink discharging speed, thereby reducing an ink discharging amount. As a result, in the case of the dither type, a sharp image without unevenness can be formed. In the case of the error diffusion type, an image with high gradability can be formed.

Title: Detergent feeding device for washing machine
Inventor: IMAI TORU
IPC: D06F39/02
Filed: 1989-03-08
Abstract: PURPOSE:To feed powdery detergent, received on the receiving surfaces of a detergent receiving part, through the forced flow of it by means of water injected from a water injecting part by a method wherein the water injecting part is formed such that a lowermost part makes approximate contact with the receiving surfaces. CONSTITUTION:Powdery detergent received on both first and second receiving surfaces 16 and 17 of a detergent receiving part 18 is fed through the forced flow of it by means of water injected from a water injecting part 20. Since the water injecting part 20 is formed in a manner that its lowermost part (the lower edge part of a pore 21) makes approximate contact with the first receiving surface 16, water injected from the water injecting part 20 flows over the first and second receiving surfaces 16 and 17 of the detergent receiving part 18 from the uppermost stream side thereof throughout the whole of the receiving surfaces, and all of powdery detergent received on the receiving surfaces 16 and 17 is forced to flow. Since no powdery detergent remains on the receiving surfaces 16 and 17 and remaining powder detergent is not accumulated thereon, this constitution enables smoothing of the following feed of the powdery detergent, and permits prevention of an amount of fed detergent from being in short supply.

IPC: H05B37/03
Filed: 1989-03-08
Abstract: PURPOSE:To detect which lamp has a broken filament among many lamps by comparing the output voltage wave-form of an AC power source due to the short circuit release set to the different value for each lamp and the short circuit release time set for each lamp, and judging which lamp has a broken filament. CONSTITUTION:The change time of the output voltage wave-form of the AC power source 2 due to the short circuit release set to the different value for each of lamps L1-Ln and the short circuit release time set for each lamp are compared to judge which lamp has a broken filament. When a broken filament is detected by a broken filament occurrence detecting section, the secondary side of transformers CT1-CTn is short-circuited by a short circuit controller, this short circuit is released for the short circuit release time, thereby the change time of the output voltage wave-form of the AC power source 2 is measured by a wave-form change time measuring section 6. This time and the short circuit release time set differently for each lamp are compared. Which lamp has a broken filament can be detected accordingly.

IPC: B41J35/28
Filed: 1983-03-31
Abstract: PURPOSE:To prevent a thermal printing ribbon from being deteriorated at the time of fitting and detaching it, by a method wherein a thermal printing ribbon is previously contained in an elongate ribbon cassette, and the cassette can be fitted to and detached from a main body of a printer in a click-fit manner. CONSTITUTION:When the first engaging and stopping part 181 side of the ribbon cassette H is lifted up, an engaging point P1 between the part 181 and the first engaging part 183 is raised along a hook part of the part 183, while the second engaging and stopping part 182 is also elastically bent, and a main body 34 of the cassette H is moved in the direction of an arrow X, whereby drawing- out of the part 181 is facilitated. The main body 34 with the part 181 disengaged is rotated further upward. The main body 34 is so rotated that a cut surface 182d on the side of the part 182 becomes substantially vertical Y toward an opening part of the second engaging part 184, and the main body 34 is drawn upward. Engagement between the part 182 and the part 184 in this condition is made only on the side of a hook part 182b. Accordingly, since the degree of engagement is reduced to about one half of that in the case where the cassette H is set to side plates 14, 15, a reaction to the cassette H can be eliminated.

Title: Digital recording signal regenerating device
Inventor: ISO YOSHIMI
IPC: G11B20/10
Filed: 1984-03-26
Abstract: PURPOSE:To realize a digital-analog converter converted to a monolithic IC, whose linearity is scarcely deteriorated, by dividing independently in the IC the ground of plural counters of a parallel integral type digital-analog converter (DAC), and a power source. CONSTITUTION:SR-FFs 204, 205 and 206 for outputting a control signal of a current switch for intermitting a current of a weighted current source are connected to a power source supply terminal 213 of an IC so that power source lines 207, 208 and 209 become independent, respectively, and have no impedance common to each other. Ground lines 210, 211 and 212 are also connected to a ground terminal 214 of the IC in the same way. When the power source and the ground line are laid out in this way, even if the pulse width of the SR-FFs 205, 206 and 204 coincides, the influence exerted on each other is reduced because the common impedance is small, and a phenomenon such as a linearity is deteriorated by digital data inputted to a DAC can be improved.
