Title: Remote image forming device control system
Inventor: FUKUSHIMA KAZUYOSHI
IPC: G03G21/00
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To prevent the fault of an image forming device at a customer and to quickly solve the trouble of the image forming device at the customer. SOLUTION: Each copying machine 1 transmits corresponding report data to a service center 200 at the time of detecting the occurrence of abnormality by a self-diagnostic function or at the time of being in the state of requiring an advance warning. Though respective clients 201a-201n store and analyze the remote report data from each copying machine 1 for each copying machine 1, they judge the content of the abnormality of a corresponding copying machine 1 based on a result when it is the analytical result of the remote report data by self-diagnostic abnormality, and perform a corresponding action and store an action method.  When the analytical result is that of the remote report data obtained by the advance warning, the prediction of the fault is executed stepwise by collating the characteristic of each copying machine 1 based on it, so that the remote report data corresponding to the level of the prediction or the history report of the action method is prepared.

Title: Superconductive junction device
Inventor: TARUYA YOSHINOBU
IPC: H01L39/22
Filed: 1989-01-13
Abstract: PURPOSE:To enable a junction device of this design to secure characteristics as a single Josephson junction and not to have such characteristics possessed of roundness peculiar to a grain boundary Josephson junction by a method wherein specified superconductive material containing oxygen as a component is formed into sandwich-type electrodes. CONSTITUTION:When a Y-Ba-Cu oxide thin film in which Y, Ba, and Cu are in the compositional ratio 1:2:3 is formed into an upper and a lower electrode, Y-Ba-Cu oxide thin films 2 and 3 are formed through a film forming method such as sputtering or the like at a high substrate temperature of 600 deg.C or more, whereby they can be made to have a superconductive property without being thermally treated after they have been formed. Furthermore, an amorphous thin film 1-10nm in thickness is formed of a Y-Ba-Cu oxide of the same composition as above through a method such as sputtering to serve as a tunnel barrier layer 4. A superconductive junction device constituted as mentioned above has not only a Josephson current but also hysteresis peculiar to a superconductive junction. Therefore, a junction device of this design does not have the roundness of a voltage-current characteristic near zero voltage peculiar to a grain boundary Josephson junction.

IPC: B41J2/055
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive ink jet head capable of being subjected to low voltage driving and having high reliability. SOLUTION: In an ink jet head, an electrode 42 is formed to the under surface of a vibration plate 41 and an individual electrode 43 is formed under the electrode 42 through a minute gap 44. In this case, when voltage is applied across the electrode 42 and the individual electrode 43, the vibration plate 41 is attracted by force of static electricity to be bent and the vol. of each ink emitting chamber 45 becomes large to receive the supply of ink from a common liquid chamber 47 through an ink inflow port 48. When applied voltage is cut off, the bent vibration plate 41 is returned to the original state to pressurize the ink in the ink emitting chamber 45. Ink is emitted from an emitting orifice 46 as ink droplets by pressurizing energy and bonded to paper to perform recording.  By filling the gap 44 with a substance with a specific dielectric constant ε*, applied voltage for generating the same force of static electricity becomes 1/√ε*.

Title: Cleaning method of semiconductor substrate
Inventor: MATSUO CHIZUKO
IPC: C11D7/26
Filed: 1997-01-16
Abstract: PROBLEM TO BE SOLVED: To reduce metal impurity concentration at the substrate surface with light beam radiation and successfully remove both metal impurity and fine particles adhered to the semiconductor substrate surface in a single tank. SOLUTION: While the surface of a semiconductor substrate 11 is radiated with the light beam of the wavelength of at least 500nm, this substrate is washed with the cleaning liquid of pH2 to 6 including organic acid of 0.0001 to 0.1wt.% and fluoric acid of 0.005 to 0.25wt.%, as required. The contaminated substrate 11 is soaked to the cleaning liquid and it is then radiated with the light beam. Thereby, the naturally oxidized film 12 on the surface of substrate can be eliminated by the fluoric acid and fine particles 13 and metal impurity 14 transfer into the liquid as shown in Fig. (b). Since the cleaning liquid has a pH of 2 to 6, fine particle becomes negative like the substrate surface.  Thereby, the metal impurity ion in the liquid becomes negative complex ion due to the complexing effect of the organic acid and fine particle and metal impurity also become negative at its surface potential like the substrate surface potential and thereby these are no longer adhered or re-adhered to the substrate as shown in Fig. (c). Here, the organic acid at the area near the substrate surface is reduced and dissociated to improve the metal impurity removing effect.

Abstract: PURPOSE: To prevent the overload on a water-wheel generator and the cavitation of a water wheel and effectively use the energy of water, by providing a unit which calculates the range of allowable load on the generator corresponding to the effective head.  
     CONSTITUTION: The signal of the load V3 on the water-wheel generator is added by an adder 23 to the signals V3-1∼V3-n of the loads on other water-wheel generators having a pressure pipe jointly with the former generator.
