A device is provided for coupling (i) a PCB sheet, which includes a first PCB and a space formed after removing a defective PCB from the PCB sheet, with (ii) a replacement second PCB received in the space and has a connecting part spaced from a periphery of the space by a channel. The device includes a PCB securing plate adapted to support the PCB sheet. PCB securing pins project from an upper surface of the PCB securing plate to be inserted into pin receiving holes of the first and second PCBs for positioning the PCBs. PCB securing tapes are integrally attached on the PCB securing plate for securing the PCB sheet and the second PCB to the PCB securing plate. An adhesive is adapted to be filled into the channel to couple, when cured, the PCB sheet and the second PCB together.

Device for coupling PCB sheet

A method and a device for coupling a PCB sheet are disclosed. If a defective PCB is found after the manufacture of continuously arranged circuit patterns, then the defective PCB sheet portion is removed to replace it with a new PCB sheet portion. That is, a defective circuit pattern sheet' is removed from continuously arranged circuit patterns of a first PCB sheet. After removal of the defective circuit pattern sheet&#x2032;, the first PCB sheetis position-located by means of a position locating means. Then the space which is formed by removing the defective circuit pattern sheet&#x2032; is filled with a second PCB sheeton which a good quality circuit patternis printed. Then the first PCB sheetand the second PCB sheetare coupled together by using an adhesive means

In a method for coupling a PCB sheet, if a defective PCB is found after the manufacture of continuously arranged circuit patterns, then the defective PCB sheet portion is removed to replace it with a new PCB sheet portion. That is, a defective circuit pattern sheet is removed from continuously arranged circuit patterns of a first PCB sheet. After removal of the defective circuit pattern sheet, the first PCB sheet is position-located by a position locator. Then, the space which is formed by removing, the defective circuit pattern sheet is filled with a second PCB sheet on which a good quality circuit pattern is printed. Then, the first PCB sheet and the second PCB sheet are coupled together by using an adhesive.

An assembling type unit track member for toy vehicles is disclosed, which can be assembled into an endless running track for toy vehicles. The assembling type unit track member for toy vehicles consists of a U shaped track member. The U shaped track member includes a bottom plate and a protuberance and a slot formed at a center of the bottom plate for being assembled to other track members. A pair of trapezoidal coupling piece and a pair of trapezoidal recesses are formed on the bottom plate and at both sides of the protuberance and the slot A pair of pillar shaped walls stand at both ends of the bottom plate and a projection and a channel are formed on each of the pillar shaped walls for being coupled to other track members. The assembling type unit track member can be produced by a single die, and therefore, the production cost can be curtailed. Further, the bulk and length of the track member are very small, and therefore, all the track members can be contained in a small box, so that the transportation, handling and storing of them are convenient. Further, the contour of the track can be arbitrarily manipulated, and therefore children will enjoy pleasure for a long time.

Assembling type unit track member for toy vehicles

A toy automobile is disclosed, in which when the toy automobile runs through a curved path, a roller of a bumper of the automobile is pushed back by the wall of the track, so that the toy automobile can run through the curved path by turning the front wheels to left or right, thereby preventing the automobile from being detached from the track, or from being overturned. Universal joints,are respectively formed on ends of the front shaft,to be connected to the front wheels. Shaft retainers,of the front wheels are respectively supported by supporting plates,of the automobile body,by means of king pins,. A bumper,is installed on a front end of the automobile body,by utilizing a guide slot,, a supporting pin,and a spring,so as to make the bumper,turnable to left and right within the limits of the guide slot,. A pair of steering bars,are respectively connected to arms,of the shaft retainers,of the front wheels. Rollers,and,are installed on both ends of the bumper,and are installed at both sides of an intermediate portion of the automobile body,, whereby the rollers,and,contact to the inside of the wall of a track T, and the bumper,is pushed back so as to steer the front wheels.
