Title: Shift controller
Inventor: NARUSE MASANORI
IPC: G05D3/12
Filed: 1990-11-20
Abstract: PURPOSE:To shift a magnetic head to its target position at a high speed by storing the information obtained by adding an error measured to the target position to the shift data when the head gets in an allowance range. CONSTITUTION:When the track information is supplied to a CPU 4 from a controller 8 and a target position is pointed, a motor 5 is controlled by the CPU 4 and a magnetic head 2 is successively shifted every track pitch. When the head 2 reaches its target track position, the stepped shift action is discontinued. A memory 7 stores the information obtained by adding an error (y) to the shift information (x) secured when the head 2 gets in an allowance range of the target position, that is, the shift information X0 corresponding to the target position. Therefore the control margin increases compared with the shift control carried out by the information X. Thus it is possible to reduce such inconvenient cases where the shift of the head 2 is impossible to its target allowable range due to the disturbance like the heat, etc. Then the shift of the head 2 is quickly completed.

Title: Method for inspecting pattern of printed circuit board
Inventor: ONISHI HIROYUKI
IPC: G06T7/00
Filed: 1990-11-19
Abstract: PURPOSE:To automatically judge the neck cutting of wiring by calculating a thinning pattern image on the basis of image data and calculating the number of the endpoints thereof within a window containing a hole image. CONSTITUTION:The wiring pattern of a printed circuit board is read to be thinned and the number of the endpoints of the thinned pattern image within the window set in the vicinity of a through-hole is calculated to judge whether neck cutting is generated. By this method, it is unnecessary to strictly judge the center of the circle in a hole image and the neck cutting of a wiring pattern can be automatically judged by a relatively simple means.

Title: Oxygen replenishing agent for activated sludge treatment tank
Inventor: YAMAMOTO ICHIRO
IPC: C02F3/12
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To eliminate dissolved-oxygen deficiency caused in an aeration tank and to prevent any malodor or insufficiency of the purification treatment from being caused by using a liquid agent consisting essentially of a water-soluble, oxygen acid- based compound as the replenishing agent for an activated sludge treatment tank. SOLUTION: This oxygen replenishing agent for an activated sludge treatment tank is a liquid agent consisting essentially of a water-soluble, oxygen acid-based compound and therefore, when added to an aeration tank, it is ionized and rapidly dissolved in wastewater in the aeration tank, wherein since this oxygen acid compound contains a large amount of oxygen in the ionic structure, when an overloaded and/or anaerobic state is caused inside the aeration tank, the oxygen deficiency within the aeration tank is immediately eliminated and also, when e.g. waste nitric acid is used as the oxygen acid-based compound, any malodor or insufficiency of wastewater purification treatment is rapidly prevented from being caused, at a low cost and without adversely affecting the biological treatment.  Thus, by injecting the replenishing agent into wastewater treatment equipment, pits, etc., for a building any malodor is prevented from being caused through the whole treatment equipment and accordingly, the protection of facilities and the environmental conservation is attained.

Abstract: PURPOSE:To perform sufficient overetching of a three-layer film while preventing damage of the interior of a semiconductor substrate when the three- layer film to become a dielectric film to be formed between a floating gate and a control gate is etched by forming the floating gate and then forming a dummy pattern for an etching mask on the substrate. CONSTITUTION:After a floating gate 14 is selectively formed on a semiconductor substrate 10 through a gate insulating film 13, a dummy pattern 15a for an etching mask is formed on the substrate 10. Then, after an ONO film 20 of a dielectric film is formed on the entire surface, the film 20 is selectively removed by etching, and then the pattern 15a is removed. When the ONO film 20 of the region I is selectively removed by etching to pattern the film 20, a dummy oxide film 15a is previously formed in a sufficient thickness as an etching mask between the film 20 of removing by etching and an active film 12 of the region I, and hence a plasma 22 for the etching is shielded by the film 15a even if selection ratio for the oxide film of the nitride film is low.

Abstract: PURPOSE:To smoothly input characters easy to see by providing a threshold for input method automatic switching dependent on the number of points of a character to perform automatic switching between direct input monitor input. CONSTITUTION:The threshold dependent upon the number of character points is provided to perform automatic switching between direct input and monitor input. That is, icons 7-6 for automatic switching or an icon 7-7 for non-select whether automatic switching of the input method should be performed or not, and the threshold and information for automatic switching or non-automatic switching are stored in a main memory 1-5 and are referred at the time of document input from a keyboard 1-8 thereafter. Direct input is automatically selected when the number of paints of the character is larger than the threshold, and monitor input is automatically selected when it is smaller, and a document is inputted by the selected method. Thus, automatic switching between direct input and monitor input is performed based on format information.

Title: Digital data output device
Inventor: HIGURE SEIJI
IPC: H03M13/15
Filed: 1995-12-04
Abstract: PROBLEM TO BE SOLVED: To allow the output device to need digital data error information and its discrimination circuit by sending error information of transmission digital data in addition to transmission digital data and allowing a receiver side to make error check in addition to detection of a transmission error. SOLUTION: When a data period elapses, at the same time a switch 2 is open, a switch 3 is closed and an error flag obtained by an error correction circuit is fed to an adder 5 via the switch 3. On the other hand, a cyclic redundancy check code CRCC is given serially to the adder 5 via an adder 4 from a generation polynomial register 1. When there is no error in data received by the generation polynomial register 1, since an error flag whose content is '0' is given to one input terminal of the adder 5, the CRCC is outputted to a post stage without any modification and when any error is in existence, the error flag whose content is '1' is given to the adder 5, the data whose logic is inverted are outputted serially.

Title: Fuel assembly
Inventor: ISHII KAZUYA
IPC: G21C3/30
Filed: 1987-12-14
Abstract: PURPOSE:To intend an increment of a reactor shutdown margin, by making an average weight ratio of a fissile uranium contained in a down stream side region to the whole fuel materials in the region, to be smaller than that of an upper stream side region. CONSTITUTION:A fuel assembly under consideration has 120 fuel rods, for example, and is broken down to be 60 fuel rods 3 which are loaded with a plutonium fuel at an upper one third region and a uranium fuel at a lower two thirds region, and 60 fuel rods 4 which are loaded with a uranium fuel for the whole region. Therefore, in this fuel assembly, an average weight ratio of a fissile uranium to the whole fuel material at the upper region is smaller than that in the lower region and, on the contrary, an average weight ratio of a fissile plutonium is larger at the upper region. In this case, an infinitive multiplication factor of neutrons at an ambient temperature can be reduced as much as about 4%DELTAk/k compared to a fuel assembly consisting a uranium fuel only, consequently, a reactor shutdown margin can be increased by about 0.9%DELTAk/k.
