Title: Connector
Inventor: TODO NOBUHISA
IPC: H01R13/436
Filed: 2000-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a connector which has no clearance between a contact and an insulator, enabling a double-lock member to be engaged smoothly with the contact and having a simple structure. SOLUTION: In Fig. (a), a small clearance C is present between the left end wall of a contact housing chamber 1A of the insulator 1 and the left end surface of the contact 2. When the double-lock member 4 is depressed from a tentative lock position shown by a solid line to a main lock position which is shown by a dotted line, the engagement part 4B of the double-lock member presses the inclined surface 2C of a second stabilizer 2B of the contact. Accordingly, the contact moves leftward as in Fig. (b) and stops, when the left end surface of the contact abuts on the left end wall of the contact housing chamber. At this time, the clearance is set to zero, and the contact is brought into a state immovable (no play) with respect to the insulator, so that the contact of the mating connector (not shown) can be connected stably to the contact 2.

Title: Device for laser beam marking
Inventor: MIZUTANI KAORU
IPC: B23K26/082
Filed: 2000-09-27
Abstract: PROBLEM TO BE SOLVED: To provide a device for laser beam marking, in which the capacity of a storage device is minimized by decreasing coordinate data stored in the storage device and which provides improved marking quality. SOLUTION: A CPU 15 provided at the device for laser beam marking outputs the coordinate data of the beginning and terminating points of a straight line to a straight line processing circuit 17 when the CPU recognizes that a line element to be marked is a straight line. Then, the straight line processing circuit 17 linearly changes with respect to time a difference in potential of a voltage signal as data of both coordinates of the starting and end points of the straight line and gives to galvanomirrors 11 and 12. Consequently, an irradiated point with a laser beam scanned by the galvanomirrors 11 and 12 linearly moves from the starting point to the end point, the straight line element is marked, and thus it is enough to store only the data of the starting and end points of the straight line into a memory 16, and a cost is decreased because the capacity of the memory 16 is minimized.
