Filed: 1986-11-12
Abstract: PURPOSE:To more effectively execute an adaptive control by controlling the characteristic of a spatial filter to a present picture element based on the correlation of the time direction of the present picture element. CONSTITUTION:The sum of the delaying quantity of a delaying element 15 and one frame delaying circuit 11 is equal to one frame.

The delaying quantity of the element 15 is selected equal to the sum of the delaying quantity of a subtracter 6, a spatial filter non-linear circuit 7 and an adder 8. Consequently, by the output of one frame delaying circuit 11 and an input signal A, a differential signal output between the frames is obtained at the subtracter 16. The output generates the output of one bit through an absolute value circuit 17 and a comparator 14. The output of the comparator 14 is given to the circuit 7 as a control signal and thus, the changing-over of the characteristic is executed.

Title: Thermal head
Inventor: SAIDA KATSUAKI
IPC: B41J2/335
Filed: 1989-10-16
Abstract: PURPOSE:To control the peak temperature of a thermal resistor uniformly by providing a thermal head itself with a temperature self-control function which does not allow the temperature of the thermal resistor to rise beyond a specific temperature level. CONSTITUTION:A thin film thermal resistor 1 consists of, for example, a material which has metallic electroconductivity properties on the low temperature side and non-metallic electroconductivity properties on the high temperature side with a temperature boundary of about 300 deg.C between the both sides. This thermal resistor 1 is provided on a substrate 6 of glazed alumina ceramic for a thermal head. The one end of the thermal resistor 1 is connected to individual electrodes 2 and the other end is connected to the first common electrode 3. The individual electrodes 2 are connected to current switching elements 4 and the second common electrode is connected to the switching elements 4. If a voltage pulse is applied to the thermal resistor 1, Joule heat is generated by the applied voltage and the resistance value of the thermal resistor 1, initiating the temperature rise of the thermal resistor 1. If the temperature reaches a metallic/non-metallic phase transition level of 300 deg.C, the resistance value of a wired part increases, shutting off the current almost entirely. Subsequently, the temperature of the thermal resistor does not reach higher than 300 deg.C. Thus the temperature of the thermal resistor can be controlled so that the peak level becomes uniform on the high and low sides.

Title: Table editing system
Inventor: FUJIMURA SHIGERU
IPC: G06F17/21
Filed: 1989-10-16
Abstract: PURPOSE:To simplify tabulating operation by determining area to be operated and executing tabulating operation within the area at the time of executing the tabulating operation. CONSTITUTION:It is supposed that the positions of a coordinate input device 101 are moved in the order of P2, P3 prior to the specification of the 2nd point after specifying the 1st point P1 by the device 101. When the position is reached to the P2, an area calculating part 102 calculates the minimum rectangular area 301 out of rectangular areas including a block 203 having the P1 and a block 206 having the P2 based upon data stored in a block constituting buffer 104. Since the area 301 includes a block 205 extruded from the area 301, the area calculating part 102 executes no operation even at the time of deciding that an area to be tabulated is not calculated. Thus the tabulating operation is executed within the objective area. Consequently the tabulating operation can be simplified.

Filed: 1989-10-19
Abstract: PURPOSE:To execute weighting of an index by using sentence structure information obtained from a relation analysis result of a sentence and sentence structure information determined from a transition of a conjunction equivalent and the subjective case of the sentence. CONSTITUTION:By the processing of each part 1 - 7, a index is extracted and generated, and in the index extracting part 3, the significance of the index is given from a sentence structure obtained from a relation structure and a connecting relation of sentence, therefore, a retrieval of a high hit rate can be executed. Also, in the index generating part 4, the index which is not expressed explicitly in a sentence is generated, therefore, the index being suitable for the subject can be generated, and moreover, in the index information editing part 6, an index generating prescription for extracting and generating a suitable index from a result of editing of the index is updated automatically at any time, therefore, as the number of times of giving the index increases, the index of high accuracy is generated automatically. In such a way, weighting of the index based on a sentence structure can be executed by a relation analysis and a sentence connecting relation decision processing.

Abstract: PURPOSE:To homogenize protection over an entire length of a thread by a method wherein a wall having a uniform thickness of a band ring is formed into a cross-sectional taper over its full length by bending it into a bellows. CONSTITUTION:An outer protector 3A for protecting a taper screw 2A engraved on an end surface of a steel pipe 1 consists of a band ring 4A made of soft material which is to be fit to the taper screw 2A and a metallic clamp band 5A which applies the band ring 4A to the taper screw 2A.

Title: Method and device for measuring accuracy of feed in machine tool
Inventor: TAKADA MIKIO
IPC: G01B21/00
Filed: 1985-11-30
Abstract: PURPOSE:To aim at enhancing the recording ability of accuracy of feed in the moving direction and in the orthogonal direction and at enhancing the function of quantitative analysis, by moving a probe of an electric or air micrometer attached to the spindle of a machine tool, along the reference plane of a master gauge secured on a table. CONSTITUTION:During measurement of accuracy of feed upon the feed system of a table being rectilinearly fed, in such a condition that a probe 6a of an electric micrometer 6 is made into contact with the reference surface 4a of one of gauge bars 4 fixed at several indexed positions, the table 1 is rectilinearly moved along the reference plane, and therefore, measured values during forward and backward movements of the prove 6a are successively read. As a result, an error in the displacement of the feed system along a direction orthogonal to the rectilinearly moving direction of the table 1 is recorded for each index angle theta of the gauge bar 4 on a recording sheet as a series of curved wave forms. If the height of the waves and the cycle period are read, it is possible to quantitatively analyze the accuracy of feed of the feed system of a machining center at any time, and it is possible to carry out the measurement with the use of time of resting of the machine tool, and so forth, thereby it is possible to prevent the productivity from lowering.

Title: Powder molding equipment for helical gear
Inventor: TOMINAGA KOJI
IPC: B30B11/02
Filed: 1989-10-18
Abstract: PURPOSE:To prevent the eccentricity of a core rod and that of a deformed central hole by forming the bottom of an upper punch so that an arcuate part side of the deformed central hole is projected under a non-arcuate part side. CONSTITUTION:A die 30 is charged with powder to make a helical gear 10, an upper punch 40 is lowered to compress the powder, the die is lowered as it is rotated, a lower punch 20 is elevated relatively and the powder is compressed from the lower part too. The powder is turned along with the rotation of the die 30 to give force to the core rod 50. Since the bottom surface 41 of the punch 40 projects the side of the arcuate part 12a of the deformed central hole 12 under the side of the non-arcuate part 12b, the powder on the side of the arcuate part 12a can be compressed with a larger force than the powder on the side of the non-arcuate part 12b can. The force Q opposing the force P generated by the rotation of the die 30 can be given to the core rod 50, both forces can be canceled to prevent the eccentricity of the core rod 50 and the deformed central hole 12 can be prevented from eccentricity. In this way, the precision of a green compact can be improved.
