Title: Screw shaft
Inventor: UMEZAWA RYOICHI
IPC: F16H25/24
Filed: 1990-02-13
Abstract: PURPOSE:To maintain accuracy in dimension for the long period of time by coating the sliding surface of a screw shaft with an ion nitrided film to give lubricity and wear resistance to the screw shaft. CONSTITUTION:The sliding surface of a screw shaft 1 is coated with an ion nitrided film 1b. A needle pin 3 fixed onto a carriage 2 is engaged with a thread groove coated with the ion nitrided film 16, and the screw shaft 1 is pressed against the pin 3 by a leaf spring 8 at all times. The sliding surface coated with the ion nitrided film 1b is given with high Vickers hardness as compared with exposed sliding surface made of stainless steel so that wear resistance is given to the shaft 1. In addition, the sliding surface 16 is small in friction coefficient as compared with the exposed sliding surfaces made of stainless steel so that more effective lubricity can thereby be given to the shaft 1. In addition, since the ion nitrided film is formed at comparatively low temperature, no excessive thermal hysteresis is given to the shaft 1. There is thereby a little fear that accuracy in dimension is affected at the time of processing.

Title: Synchronous throw-in confirming device for brushless synchronous motor
Inventor: HIGUCHI SATORU
IPC: H02P1/46
Filed: 1990-02-13
Abstract: PURPOSE:To detect the synchronous throw-in timing of a synchronous motor accurately by setting the initial exciting amount of a brushless synchronous motor slightly higher than the exciting amount for generating a no-load rated voltage. CONSTITUTION:During asynchronous starting operation of a brushless synchronous motor 6, reactive power is fed from a power supply to the brushless synchronous motor 6 and thereby a reactive power relay 5 does not function. When an appropriate phase throw-in unit 8 functions to synchronize the brushless synchronous motor 6, exciting amount at that time exceeds that for generating a no-load rated voltage and thereby reactive power is fed from the synchronous motor 6 to the power supply. Consequently, the reactive power relay 5 functions. At that time, an external signal is provided from the reactive power relay 5 and synchronization can be detected reliably. By such arrangement, synchronous throw-in timing of the brushless motor 6 provided with the appropriate phase synchronous throw-in unit 8 can be detected accurately.

Title: Bending method using combined machine of heating and bending
Inventor: KATO SEIJI
IPC: B23K26/00
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To precisely bend by generating the heat deformation caused by heating the internal side of a bending line and correcting the bending angle to a requiring angle after bending of a part being not able to bend in consideration of the spring back. SOLUTION: In order to bend a line L4 which is not able to be bent in consideration of the spring back, a line L2 is bent until knocking without considering the spring back, and then it is judged whether its bent angle after being returned caused on the spring back is matched to the requiring angle or not. In the case of being not yet reached to the requiring angle, the internal side of bending direction of the line L4 is irradiated with a laser beam from a laser machining head and the heat deformation is generated. On the result, because the opening of the bending line generated with the spring back is corrected, also about the part being not able to be bent in consideration of the spring back, the precise bending can be realized.

Title: Conversion candidate display method and device for read input character string
Inventor: NAKAJIMA AKIRA
IPC: G06F17/22
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To easily and surely select the conversion candidates by showing these candidates only in a part of a converted character string when a long read input character string is converted into a desired character string consisting of plural divided character units. SOLUTION: When a character 'TEION KANKYO' is inputted in HIRAGANA (cursive form of Japanese syllabary), the first KANJI (Chinese character) candidate of 'TEION KANKYO' is shown in a text area 20 of a display device 201 as a result of KANA (Japanese syllabary)/KANJI conversion. If an operator desires another KANJI string for 'TEION KANKYO', the first KANJI string shown in the area 20 must be corrected. A candidate display part 203 shows the candidate display example of the first words for the input character string 'TEION KANKYO' right after the start of correction. Thus, it's possible to easily and surely select the conversion candidates with no candidate character string got out of a display screen.
