Title: Production of wire for dot printer
Inventor: TAKEHARA TAKASHI
IPC: B41J2/25
Filed: 1994-10-03
Abstract: PURPOSE: To suppress the trouble such as an increase in the number of processing processes as a whole or the occurrence of bending by cutting a strand into specific length and processing the leading end of a wire so as to remove the edge thereof before applying barrel-polishing thereto. CONSTITUTION: Since the edge 3a formed by the outer peripheral surface 1a of a wire (a) and the leading end surface thereof is sharp, the insertion of the wire (a) in the guide hole of a wire guide is difficult. As one example, a drawing B shows a state such that the edge of the wire (a) is ground into a truncated cone shape by chamfering processing. A drawing C shows such a state that the ground edge (b) is subjected to barrel-polishing and the skin of the outer peripheral surface and the fatigue strength under the outer peripheral surface are improved and edges 4c, 5c are enhanced in the insertion properties into the guide hole.  A leading end surface and a conical surface 6c are slightly improved in surface roughness and, from the aspect of the insertion properties of the guide, the grinding meshes of the conical surface are desirably parallel or oblique with respect to a bus as shown by (c). A drawing D shows the end surface 2d subjected to beads blasting treatment of C.

IPC: F02P5/15
Filed: 1991-09-19
Abstract: PURPOSE:To lengthen a time in which, an angle of lead is reset in relation to a high knock, and to perform effective protection of an engine by setting the operation parameter of an ignition timing according to a knock intensity provided by applying high weighing on a resonance frequency of a high cycle. CONSTITUTION:A control unit 9 receives detection signals from an intake air amount sensor 2, a crank angle sensor 12, and a knock sensor 17 etc., and computes an ignition timing and a fuel injection amount. In this control unit, the given number of signals from the knock sensor 17 are inputted at intervals of a constant sampling time. By analysing the frequency of an FFT, etc., a vibration level equivalent to the resonance frequency of knocking is calculated. Given weighing is applied on the vibration level of each frequency to determine each weighed vibration level, which is added sequentially to determine a knock intensity. Through comparison of the knock intensity with a given threshold, the occurrence of knocking is decided. When the knocking occurs, an ignition timing is delayed by a given angle of delay amount according to the knock intensity.

Filed: 1997-09-04
Abstract: PROBLEM TO BE SOLVED: To form a memory device where electrons are easily extracted or injected, a leakage current can be restrained, and data is hardly volatilized by a method wherein a control gate electrode and an erase electrode are formed on a floating gate electrode through the intermediary of an insulating film. SOLUTION: When electrons are extracted from a floating gate electrode 4, a voltage is applied to an erase electrode, and a silicon substrate 1, a control gate electrode 6, a source region, and a drain region are kept at a ground potential. By this setup, holes are collected between the erase electrode 9 and a natural oxide film 5d and moved to an interface between a silicon nitride film 5b and a silicon oxide film 5a, and the holes and electrons located in the floating gate electrode 4 are combined together, whereby electrons are extracted from the floating gate electrode 4. Therefore, electrons can be easily extracted with a low voltage, and data are hardly volatilizgd if electrical charge is retained in the floating gate electrode 4 once.

IPC: E01H5/04
Filed: 1994-08-26
Abstract: PURPOSE: To evenly press down a grader blade on a snow face and increase the snow-clearing work efficiency, by detecting the lateral acceleration at the time of turning travel by an acceleration sensor and stretching a hydraulic cylinder inside the turning direction, on clearing away snow. CONSTITUTION: A hydraulic cylinder 50 is arranged at both right and left sides of the center line in the front and rear direction of a car body and connected to a grader blade 30 which is moved up and down against a snow face by the extension and contraction of respective hydraulic cylinders. When the vehicle 10 turns, the generated lateral acceleration is detected by an acceleration sensor 76 and the output signal is transmitted to a controller 70. The controller 70 actuates a hydraulic control valve 78 to stretch the hydraulic cylinder 50 at the turning side and press down the turning direction side of the blade 30. In this way, snow can be removed efficiently even when turning to the right or to the left in a mountain path with many curved roads or at a crossing and a low cost snow-clearing vehicle 10 with a simple structure can be obtained.

Title: System for controlling opening of file
Inventor: IWASAKI MOTOAKI
IPC: G06F15/00
Filed: 1990-09-12
Abstract: PURPOSE:To shorten a restarting process by every on-line system or batch job by opening an information saving file on the basis of catalogue information and volume information. CONSTITUTION:Open information is stored in an open information saving file 80 after a blocking process so as to reduce the number of I/O operations required for making system starting/restarting processes. While a system is in an on-line state, in addition, the number of I/O operations to catalogue information 50 and volume information 60 and 61 required at file opening time can be reduced at the time of performing the next system starting/restarting process even when closing or opening of files 30-33 is generated by always checking the open information already saved to the file 80 and new open information and saving the open information to be used to the file 80. Therefore, the file opening time is reduced during the system starting/restarting process.

Abstract: PURPOSE:To obtain a clear image without need of correction and interpolation processing of picture element data by alternately overlapping to arrange a plurality of semiconductor radiation detecting elements each comprising a matrix of picture elements in the direction along the line or the row of a picture element arrangement. CONSTITUTION:A plurality of radiation detection element arraies A are alternately overlapped to arrange on a printed board 4 in the direction along the line or the row of a picture element P arrangement and the picture element P of both ends of each array A is lapped over to arrange to constitute a multi-type semiconductor radiation detector S and further a drive mechanism 5 for scanning the whole S of the detector in the direction of right angles with the arrangement of each array A by the effective picture element part of the array A is provided. However, a signal taking- out electrode corresponding to the picture element P of a row part of the circumferential part of the array A is not connected to a signal processing circuit and only the electrode of the picture element p except for it is connected to the signal processing circuit.

Filed: 1993-09-28
Abstract: PURPOSE:To reduce deterioration in speech recognition rate due to environmental changes by finding and matching the difference vector from an input vector, generated while a mean vector is updated at the time of recognition, with a standard pattern.
