Title: Production of high-tenacity nylon 6 filament yarn
Inventor: HIRAHATA HIROTSUGU
IPC: D01D5/06
Filed: 1984-01-31
Abstract: PURPOSE:To obtain the titled filament yarn consisting of high-molecular nylon 6, by dissolving nylon 6 polymer having a specific relative viscosity and molecular weight distribution value in formic acid, etc., extruding the resultant solution through an orifice, coagulating the resultant filaments in a coagulation bath, and winding the coagulated filament yarn. CONSTITUTION:Nylon 6 polymer having >=5.0 relative viscosity (measured by using a 1.0g/dl solution in concentrated sulfuric acid at 20 deg.C) and <=6.5 molecular weight distribution value (MW/Mn) is dissolved in formic acid or an aqueous solution thereof to form a spinning solution, which is then extruded through an orifice, introduced into a coagulation bath and coagulated to give a filament yarn. The resultant filament yarn is then continuously or once wound and hot-drawn to afford the aimed filament yarn. Preferably, the aqueous solution of the formic acid contains >=80wt% formic acid, and the nylon 6 filament yarn is hot-drawn at >=5 times draw ratio.

Title: Dynamic sensor and detecting mechanism using it
Inventor: HONMA TOSHIO
IPC: G01G3/14
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a dynamic sensor which omits labor in its manufacture, which reduces an irregularity in a characteristic and in which a cylindrical body is fitted easily to other members by a method wherein one side edge in the length direction of a chip is fixed to the inner circumferential face of the cylindrical body and a gap is formed between the other side edge and the inner circumferential face of the cylindrical body. SOLUTION: The width W of a chip 11 at a load sensor 10 is formed to be a little small as compared with the inside diameter of a cylindrical body 4. Then, out of side edges 11a, 11b along the length direction of the chip 11, the side edge 11a on one side is welded and fixed, by an electron beam or the like, to the inner circumferential face 4a of the cylindrical body 4, and a gap (g) is formed between the side edge 11b on the other side and the inner circumferential face 4a. The side edges 11a, 11b may be formed on flat faces at right angles to a face 11c on which a strain gage 2 is formed. Thereby, since the machining accuracy of the cylindrical body 4 and the chip or a requirement regarding the shape of the side edges 11a, 11b is relaxed, the costs of the load sensor can be reduced.  In addition, since an internal stress is not generated when the chip 11 is fitted to, and mounted on, the cylindrical body 4, an irregularity in the characteristic of every sensor 10 is reduced, and the reliability of the sensor can be enhanced.

Filed: 1994-02-15
Abstract: PURPOSE:To facilitate correction by informing a user of the unmatching part between picture data of an inputted musical score (input picture data) and picture data of the musical score reconstituted based on the recognition result (reconstituted picture data). CONSTITUTION:The musical score is scanned by a scanner 13 to take in the input picture data. Symbols such as notes are extracted from this input picture data to generate music data (code data), and reconstituted picture data is generated based on this music data. Thereafter, noncoincidence part picture data indicating only the noncoincidence part between input picture data and reconstituted picture data is generated and is displayed as a picture on a display device 15 to inform the user of the recognition error part of input picture data. In this case, noncoincidence part picture data is displayed over reconstituted picture data in a different color, and thereby, the noncoincidence part between input picture data and reconstituted picture data is clarified to enable the user to easily discriminate the recognition error. Thus, correction is surely performed.

Title: Microcomputer unit for quickly searching identification block
Inventor: PEETAA HORUTSUNAA
IPC: G06F17/30
Filed: 1982-02-09
Abstract: A micro-computer system for data processing and for the rapid location of a characteristic block has a working store which is organized so that it can be used as a conventional working store with a data width of, for example, one byte. This working store contains a data file storage zone for storing, along with other data, a plurality of blocks of multi-byte characteristics. Several read-write stores, all of which contain one or more bytes of the block of characteristics, are read out simultaneously, while the data ports of the read-write stores are cut off from the data bus. The comparison with the combinations searched for is carried out via comparators which compare the data read from the read-write stores with the combinations searched for, which are intermediately stored. The outputs of the comparators are connected to the inputs of an AND gate which produces an identity signal which terminates the searching.

Title: Thermal printing control circuit
Inventor: KAMIYAMA TAKESHI
IPC: B41J2/38
Filed: 1987-01-30
Abstract: PURPOSE:To contrive a longer life of a thermal head as well as a higher printing speed, by applying a preheating pulse signal to respective heating elements to heat the thermal head to a fixed temperature. CONSTITUTION:In the period that a printing control signal (a) of L level representing a continuous printing action period is inputted, the temperature of a thermal head 13 is kept at nearly a printing optimum temperature Tm. Then, with the change of the printing control signal (a) to H level, which represents that the continuous printing action period came to an end and changed-over to a stand-by period lasting until the start of a next continuous printing action, the temperature of the thermal head 13 is controlled to a preheating temperature Tp (=40 deg.C) substantially higher than a normal temperature Ts (=25 deg.C). Therefore, the thermal head 13 controlled to be at the preheating temperature Tp can be sufficiently increased to the printing optimum temperature Tm (=70 deg.C) with the amount of heat being lower than that required to the increase from the normal temperature Ts (=25 deg.C) directly to the printing optimum temperature Tm (=70 deg.C). At the start of printing a series of bar code, a pulse width T2 of a heating pulse signal (d) can be reduced. In this manner, a paper feed speed of printing paper is increased, which enables the reduction of an H-level period T1 of a printing command signal (b) thereby resulting in the enhancement of a printing speed.
