Title: Method for correcting soldering
Inventor: KOTO YASUO
IPC: B23K3/00
Filed: 1989-03-17
Abstract: PURPOSE:To surely correct only soldered points where correction is required corresponding to the kind of defects by automatically stratifying soldering defects into an insufficient-solder defect and solder-bridge defect at every defective point based on inspection information and adding solder to points where the insufficient-solder defect occurs, with the solder-bridge defect being modified by cutting solder bridges. CONSTITUTION:An inspection-result stratifying section 11 judges whether or not an inspected printed circuit board is to be modified on the basis of the content of received data. When a circuit board is judged as a defective one, the section 11 classifies the kind of defects at every defective point. In case a defect is judged as an insufficient-solder defect or solder-bridge defect, a correcting operation controlling section 10 reads out necessary one out of correcting operation parameters for every kind of product and every soldering point previously registered in a correcting operation parameter table 9 in accordance with the content of received data at each step. The insufficient-solder or solder-bridge defect is corrected in the next step in accordance with the read-out parameter.

IPC: G02B6/255
Filed: 1993-03-03
Abstract: PURPOSE:To stably advance optical fibers so that the optical fibers are well connected by clamping the optical fibers with a part of the bottom end parts of clamping pieces. CONSTITUTION:A part (clamping part 190) at the bottom end 19 of the wedge- shaped front end of the clamping piece 18 is made to remain and the other parts thereof are notched to form a non-clamping part 192 in order to clamp (touch and press) the optical fiber with a part of the bottom end of the clamping piece. The clamping part may be the front part as well and may be the other parts, for example, an intermediate part and a rear part. Both flanks in the rear part of the clamping piece 18 come into contact with the top end of the inside surface of a V-groove 14 and becomes stable when the force F by a spring acts on the clamping piece 18. The clamping piece 18 comes into contact with the optical fiber 16 only with the small area of the clamping part 190 and a part of the force F of the spring acts to push down the clamping part 190 and, therefore, the clamping piece 18 keeps to stably press the optical fiber 16 without allowing its front end to float up at the time of advancing the optical fiber 16.

Title: Power window regulator device
Inventor: ISHIDA TOSHIHIKO
IPC: H02K11/00
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to surely detect an insertion between window glass and door widow frame by providing a ring spring between driving body and driven body, and detecting relative displacement between the driving body and driven body and current increment to an electric motor to lower a window glass. SOLUTION: An output shaft 10 bears a driven body 11 of a tension plate so as to oppose it to a ring spring 9, and a shoe capable of slidably contacting with a print substrate body 13 is placed to a boss section 6 of a driving body 3 through a circular arc hole 17. When load is applied to the window glass, a claw 12 of the driven body 11 is pushed in one end face 8, and relative revolution occurs between the driving body 3 and driven body 11. During the rising of the window glass, when the shoe is brought into contact with a second switch to turn it an ON state, a control section detects an insertion, and the window glass during the rising is lowered. While, since sliding resistance during the falling of the window glass is high in the case of low temperature, the insertion measures increased ratio of power volume to an electric motor 1 to use a device for detecting the insertion.

Abstract: PURPOSE:To discriminate a slag metal inexpensively with good workability by providing an electromagnetic oscillation detector to an attaching and detaching device for a charging nozzle of a vessel for molten metal and detecting the decrease in the fluctuation value of the specific frequency of the detected signal thereof as the point where the passage of the slag starts. CONSTITUTION:An electromagnetic oscillation detector 8 is disposed without contacting to an attaching and detaching device 2 for a nozzle 2 which charges the molten steel in a ladle 1 into a tundish 3. The oscillation signal which is detected with the detector 8 is amplified 9 and is differentiated twice with differentiation circuits 10, 11. The outputs thereof are passed through a band-pass filter 12 which allows the passage of only the specific frequency band. The above-described signal past the filter 12 is inputted to a half-wave or full-wave rectifier circuit 13, by which the signal is converted to the signal that bases on an output voltage with zero V. Said signal is further passed through a low-pass filter 14 and a half-wave or full-wave rectifier circuit 15 and is further passed through a low-pass filter 16, from which an envelope is drawn out. On the other hand, the signal output set with a frequency is inputted to a comparator 10, by which the output is compared and calculated with the set signal of a setter 18 and the outflow of the slag is detected when the signal level of the filter 16 attains a specified value or below. An alarm device 19 is then operated.

Title: Composite-sensor tracking device
Inventor: SATO FUMIMASA
IPC: F41G3/00
Filed: 1993-03-26
Abstract: PURPOSE:To limit the radiation of radio waves and, at the same time, to cope with tracing by automatically switching a TV sensor by adding a distance analogizing and discriminating circuit and change-over switch to the TV sensor and analogizing the distance to a target from the size of the target. CONSTITUTION:When a TV sensor tracks a target, a signal corresponding to the size of the target is inputted to a comparator 17 from a target detecting section 7. When the state of the target (e.g. lateral or front target) is inputted from a target indicating section 13 in this state, selectors 14a-14b are switched and one threshold is selected from between ROMs 15a-15b. In addition, a mode selector 16 selects either a kind threshold or attitude threshold and outputs the selected threshold to the comparator circuit 17. When the input from the section 7 exceeds the input from the selector 16, a radar sensor is actuated by actuating a relay 19 by means of a relay driver 18 and turning on a change- over switch 12. Namely, the radiation of radio waves from a radar which is in danger of being traced is suppressed until this tracking device become possible to cope with the tracing back.
