Title: Electronic component installation device
Inventor: MIURA IZUMI
IPC: B23P21/00
Filed: 1992-05-27
Abstract: PURPOSE:To recognize an insertion hole without being influenced by a burr or a residue generated in a punching process and to insert an electronic component with accuracy through an image recognition of the electronic component insertion hole of a printed board and by inserting the electronic component into the hole of the printed board after correcting a position of an X-Y table on which the printed board is set. CONSTITUTION:A printed board 1 is carried by a loader rail 2 to be set on an X-Y table 3. The X-Y table 3 is moved based on the preliminarily determined NC data and insertion holes of the printed board 1 are positioned in order under a recognition camera 10 for visual recognition processing. Picture data of the recognition camera 10 is sent to a recognition treatment equipment 11 and then NC data of actual insertion holes is computated and the computated result is sent to a main controller 9. The main controller 9 compares the NC data obtained from the recognition processing with the preliminarily set NC data and then it requires NC data of a deviation component for correcting the deviation between the two data. The X-Y table 3 moves based on this NC data and then the insertion holes are positioned under a component insertion section 6.

Title: Copying device for arc welding
Inventor: MANABE YUKIO
IPC: B23K9/127
Filed: 1980-09-30
Abstract: PURPOSE: To perform copying accurately and easily by inputting the shadow picture of the weld zone received by a TV camera to an operator via an image processor, operating the deviation of a welding wire from a groove here, inputting this to a control circuit and controlling this so as to make the deviation zero.  
     CONSTITUTION: Laser light 20 emitted from a laser light generator 16 is expanded by optical lenses 17, 18 and irradiates a welding arc 1 and a groove 3. The laser 20 reflected by the irradiated part passes through a band pass filter 10 together with white arc light 1, and is shut off of the greater part of the arc light. This light is made incident to a TV camera 13. The shadow picture of the weld zone received with the TV camera 13 in this way is inputted to an image processor 14, by which it is converted to a black and white varying density binary image. This image is inputted to an arithmetic unit 15, which in turn operates the deviation from the center of the groove and the center of the torch, and emits a control signal so as to make the deviation zero. On receiving this, a motor 6 is driven to correct the position of a welding torch 7, whereby the copying operation is accomplisehd automatically.

IPC: F21V11/00
Filed: 1985-06-20
Abstract: PURPOSE:To prevent unexposed parts and exposed parts of a photosensitive resin layer from remaining in space parts when an auxiliary layer consisting of a photosensitive resin is stripped by providing said auxiliary layer to at least the bottom surface of the photosensitive resin layer constituting the body of a louver and subjecting these layers to exposing and developing. CONSTITUTION:The film-like auxiliary layer 12 consisting of the photosensitive resin is laminated on a base film 11 and further the photosensitive resin layer 13 is laminated thereon. A negative film 14 having a prescribed pattern is superposed thereon and UV rays 15 are irradiated there on to simultaneously expose the resin layer 13 and the auxiliary layer 12. The exposed parts of the resin layer 13 remain and rectangular projections 13a are formed when the unexposed parts are removed by development. Remaining parts 12a are formed to the layer 12 in this stage. Only the projections 13a remain when said parts are stripped and therefore a light absorptive material is stuck over the entire surface to form light shielding parts 16. A light shielding plate A arranged, at prescribed intervals, with the projections 13a coated with the light shielding parts 16 is thus obtd. The spaces between the projections 13a are space parts 17 through which rays are transmitted.

Abstract: PURPOSE:To provide smooth running for a vehicle by controlling braking pressure according to acceleration or deceleration speed and slippage. CONSTITUTION:When a controlling circuit 17 identifies an idled state of wheels from slippage, the circuit 17 outputs signal. This signal operates a braking liquid reflux preventing actuator 18. If braking pressure is demanded to be increased, the actuator 18 operates a pressure increasing actuator 19a or 19b while if the pressure is demanded to be decreased, the actuator 18 operates a pressure reducing actuator 20a or 20b. When the braking pressure is kept in the increased state, the braking liquid runs from a pressure accumulator 23 through the pressure increasing actuator 19a or 19b and then is sent to front wheel brakes 15a and 15b. On the other hand, if the braking pressure is kept in the decreased state, the braking liquid passes through the pressure reducing actuator 20a or 20b and then is fed back into a reservoir chamber 21 via a duct 14.
