Patent JP-H09312381-A (JP)
Title: Semiconductor device and manufacture thereof
Inventor: MIKI HIROSHI
IPC: H01L27/108
Filed: 1996-05-23
Abstract: PROBLEM TO BE SOLVED: To obtain a stable high-reliability capacitor by heat treating a dielectric film between a first and a second electrodes made of a conductive film and dielectric film having an electric flux density-electrolytic strength characteristic showing a hysteresis into a film involving a reformed film having no hysteresis. SOLUTION: 1) A Pt film is formed on a Si substrate 302 by the DC sputtering to form lower electrodes 302. 2) A material soln. is spin-coated on the whole surface by the sol-gel method to form an amorphous film 401 having a ferroelectric compsn. 3) It is dried to remove the solvent from this film 401 and the film 401 is rapidly heated to crystallize it to form a PZT film 403. 4) After forming a Pt film, upper electrodes 501 are formed and this film 403 is reformed in a N atmosphere by a second heat treatment to form a reformed PZT film 601. This eliminates the operation instability of a capacitor due to the ferroelectric property to thereby reduce the leak current.

Title: Manufacture of liquid-crystal display device
Inventor: NAKA TOSHIAKI
IPC: G02F1/1337
Filed: 1983-07-16
Abstract: PURPOSE:To prevent display even in case of electrode crossing at a wiring part and making a wiring pattern thick to reduce wire breaking defects in pattern formation and to improve the yield by varying a threshold voltage partially in a liquid-crystal panel. CONSTITUTION:A display driving voltage varies with the extent of rubbing in the formation of a molecule oriented film, which is utilized to increase the extent of rubbing partially only at a part A and make the threshold voltage of driving high, so that liquid crystal is turned on with a driving voltage for display. Then, the variation with the extent of rubbing is utilized in the formation of polyimide, etc., to rub a display part (segment part) at a low threshold voltage V1. The wiring part (part A) is so treated as to obtain V2, and actual driving is performed below V2; the segment part is displayed, but the wiring part is not displayed, so the wiring pattern is made thick.

Title: Production of formamide
Inventor: SATO SHINICHI
IPC: C07C231/02
Filed: 1993-05-31
Abstract: PURPOSE:To obtain formamide hardly containing any impurities by reacting a formic acid ester with ammonia in the presence of an alcohol under anhydrous and catalyst-free conditions. CONSTITUTION:A formic acid ester is made to react with ammonia in the presence of an alcohol of >=20wt.%, preferably >=30-100wt.% based on the formic acid ester at 10-40 deg.C, preferably 10-30 deg.C under anhydrous and catalyst-free conditions to provide the objective formamide. The formamide obtained by this method contains hardly any formic acid which acts as an acid, ammonium formate and diformamide, thus the method is optimum, especially for synthesizing N-(alpha-hydroxyethyl) formamide using a basic catalyst. Since formic acid produced when polyvinylamine is produced by hydrolyzing a polymer of N- vinylformamide is recovered as a formic acid ester and can be utilized as a raw material in the above reaction, this method has large merit in production fields of n-vinylformamide and polyvinylamine.

Title: Flow quantity display device for grains measuring and sorting device
Inventor: SATAKE SATORU
IPC: B07B1/22
Filed: 1994-03-31
Abstract: PURPOSE:To enable the measurement of the only flow quantity in the steady flow-out condition without providing a sensor or the like by stopping the measurement of the flow quantity when the increasing weight per a unit time exceeds a prescribed value or when the measurement value achieves the predetermined value just before the set weight value. CONSTITUTION:A sorting net cylinder 4 and a spiral body 5 are driven by a motor 3 so as to enable the measurement of flow quantity. Unpolished rice flows out of a supplying hopper 6, and the broken grains are eliminated during flowing down a spiral way 5. The aligned unpolished rice 9 is fed to a grains tank 9, and filled in a package bag 33 from an outlet 13. At this stage, the measurement display of weight and the measurement of flow quantity are started. In this case, flow quantity is measured on the basis of the weight change DELTAW per a constant time DELTAt, but the display is not performed at the first cycle after starting the measurement. At the only time when the value of DELTAtXDELTAW is less than 3.0, display is performed as the display of the flow quantity measured at this time. Furthermore, when the weight measurement value achieves the predetermined value just before the set value, the measurement of flow quantity is stopped. As a result, the display of the measurement in the only ordinary flow-out condition can be performed without providing a sensor or the like.

Title: Control method at time of malfunction of pressure sensor
Inventor: SASAKI ATSUSHI
IPC: F02D41/22
Filed: 1990-05-19
Abstract: PURPOSE:To suppress an idling speed at a neutral range operation as mush as possible by setting a first alternate value at the neutral range operation of an automatic transmission to a larger value than a second alternate value at the driving range operation. CONSTITUTION:A first alternate value is set to a required value for maintaining an idling condition. At the time of malfunction of a pressure sensor 12, in the idling condition of an engine and in the case an automatic transmission 1 is operated in a neutral range, an intake air quantity is calculated based on a first alternate value, and fuel supply is performed. At the time of malfunction of the pressure sensor 12, in the idling condition and in the case the automatic transmission 1 is operated in a driving range, it is changed over from the first alternate value to the second alternate value. A fuel quantity supplied to a combustion chamber is increased more than the case in the neutral range so as to increase the load.

Title: Weir made of vibrationproof rubber
Inventor: ITO KENICHI
IPC: E02B7/20
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To disperse an overflow stream while preventing breakage of fins and prevent vibration of a bag-shaped body by providing netlike fins having one or more openings of a specified size at the nearby position of the top of the rubber bag-shaped body constituting a rubber weir. SOLUTION: A rubber-made bag-shaped body 1 constituting a rubber weir is fixed to a river bed by using fixing metal fixtures 2. One or more netlike fins 4 having openings of 1-10 cm in one side thereof are formed at the top of the rubber-made bag-shaped body 1. Since the netlike fin 4 randomizes the overflow water stream of the rubber weir and lessens a negative pressure between the rubber-made bag-shaped body 1 and the overflow water, the vibration of the rubber weir can be reduced. Further, colliding impulses of the overflow water against the fins 4 can be absorbed and secondary vibration and noise can be remarkably reduced.

Abstract: PROBLEM TO BE SOLVED: To enlarge a dynamic range without enlarging a chip area by changing the length of first and second electric charge storage time, forming the image signals of the same scale based on an obtained electric charge and synthesizing them. SOLUTION: A solid-state image pickup element 3 outputs the image signals for two times. That is, the image signal formed based on the electric charge stored in a photodiode during the first storage time is outputted as a first image signal and the image formed based on the electric charge stored in the photodiode during the second storage time thereafter is outputted as a second image signal. Memories 7 and 8 can respectively store the images of one frame. The memories 7 and 8 respectively store first and second image signals supplied from an A/D converter 6. An image synthesis processor 9 synthesizes the first and second image signals stored in the memories 7 and 8, generates the image signals having the wide dynamic range and outputs them to the outside.
