IPC: D06F39/00
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce the number of switches and to simplify electric circuit configuration for inputting. SOLUTION: At a setting device 39, a membrane switch part 44 has a resistor 46 and a conductive sheet 47 while letting them face each other with a gap inbetween. When the conductive sheet 47 is pressed through a waterproof sheet 36a to the resistor 46 by manual operation and conducted in contact, a resistance value corresponding to its conducted position is outputted as an electric signal. This electric signal is analog/digital(A/D) converted by an A/D converting part and corresponding to the digital value applied from this A/D converting part, an input recognizing means recognizes the set contents of inputted contents. Namely, when the membrane switch part 44 is pressed at various positions, corresponding to these positions, the input recognizing means reocgnizes different set contents.

Title: Semiconductor device and its manufacture
Inventor: MOTOWAKI YOSHIHIRO
IPC: H01L27/04
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To simultaneously manufacture a capacitor section in the manufacturing process of a transistor or resistor by reducing the electrode dependence or leakage current of a capacitor by making the thickness of the upper oxide film of an ONO film(oxide film/silicon nitride film/oxide film) thicker than that of the lower oxide film of the ONO film. SOLUTION: An ONO film which is the dielectric film of a capacitor is composed at least of three layers of an oxide film 5, a nitride film 3, and an oxide film 2. The thickness of the upper oxide film 2 is made thicker than that of the lower oxide film 5. At the time of forming the ONO film, for example, after the lower silicon oxide film 5 is formed to a thickness of 3-7 nm and the silicon nitride film 3 having a thickness of about 12 nm is formed on the lower oxide film 5, the upper silicon oxide film 2 is formed to a thickness of 5-10 nm which is thicker than the lower film 5. When the ONO film is constituted in the above-mentioned way, a highly reliable capacitor which is reduced in polarity dependence and leakage current caused by load voltages and has a larger unit capacitance than the conventional capacitor has can be obtained.

Abstract: PURPOSE:To produce the alloy cast ingot for a rare earth metal-iron permanent magnet having excellent magnetic characteristics by rapidly cooling a rare earth metal-iron alloy melt to uniformly solidify under specific cooling conditions, thereby forming a specific crystal structure. CONSTITUTION:The alloy cast ingot for the rare earth metal-iron permanent magnet is formed of the crystal structure which contains >=90vol.% crystal having 0.1 to 100mum crystal grain sizes in a minor axis direction and 0.1 to 100mum in a major axis direction and exerts the best influence on the magnetic characteristics. This crystal structure is formed by uniformly solidifying the melt under the cooling conditions of 10 to 1000 deg.C/sec cooling rate and 10 to 500 deg.C supercooling rate. This cooling is preferably executed by using a single roll, etc., and casting the melt to about 0.05 to 20mm. The alpha-Fe and/or gamma-Fe of<20mum grain size which is peritectic nucleus is finely dispersed into the main phase crystal grains of the resulted alloy cast ingot.

Title: Toner transfer device
Inventor: ARAI MAKOTO
IPC: G03G15/08
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To prevent the reverse flow of toner to air supply ports, from which air is blown into a screw pump in order to cause toner to flow, by arranging supply ports for supplying air to the screw pump from an air supply means onto the screw pump. SOLUTION: An air pump blows air approximately 0.5-1 liter/min. in amount into a space (d) between the rotor 332 and stator 331 of the screw pump 330, through an air supply pipe, from the air supply ports 351a and 351b. This promotes the flow of toner sent out of a powder pump and ensures toner transfer more. Because, in this case, the air supply ports 351a and 351b are provided on the supply ports 338a and 338b, carried toner is prevented from flowing reversely to the air pump through the air supply ports 351a and 351b. Thus, the stable amount of air can be blown into the space at all times.

Abstract: PURPOSE: To effectively correct various aberrations of the optical system by using real numbers larger than 2 as power number, as aspherical terms, when the horizontal distance orthogonal to tangential plane at the vertex of the optical plane is expressed as a function of the height from optical axis.  
     CONSTITUTION: When with the optical plane shape at the optical plane S rotatatively symmetrical with its optical axis as a center the horizontal distance (x) orthogonal to the tangential plane at the vertex O of the optical plane from an arbitrary point Q on the optical plane S is expressed as a function of the absolute value of the height (h) from the optical axis of the arbitrary point Q, correction of various aberrations of the optical system is effectively performed by using the optical plane which uses aspherical face in which said function includes the term of h p . The use of a real number larger than 2 and not even number for this power number (p) enables effective aberration correction to be performed and the continuity of the value of the power numbers improves the degree of freedom in design.

Title: Envelope printing method using electrophotographic device, envelope forming/printing method, and envelope forming paper used for said method
Inventor: MAEDA TERUO
IPC: B41J3/407
Filed: 1989-05-25
Abstract: PURPOSE:To apply printing directly on an envelope without the occurrence of wrinkle or others using an electrophotographic device by a method wherein the envelope is printed with a predetermined image while being inserted onto a recording paper feed path in the state that overlap parts are disposed on the both ends of an edge orthogonal to an inserting direction. CONSTITUTION:An image printing is carried out in the state that a part where wrinkle or curl is easy to generate is eliminated and only part inside overlap parts exists at the time of the insertion of an envelope. Namely, the envelope in use having overlap parts 11 at least on the both ends thereof is printed with a predetermined image while being inserted onto a recording paper feed path in the state that the overlap parts 11 are disposed on the both ends of an edge orthogonal to an inserting direction. In this case, the overlap parts 11 are formed to be tapered, i.e. gradually smaller in width, along the inserting direction. In this manner, if a pressure or load deviation is generated in the vicinity of the overlap parts 11, this can be released to some extent, and the effect can be accomplished more smoothly. When printing is directly applied on the envelop using an electrophotographic device, a smooth and continuous printing can be conducted without the occurrence of wrinkle, splash in printing, curl, askew paper feed, or the like.
