Title: Surge protection circuit of subscriber's line
Inventor: MIYAGAWA TAKESHI
IPC: H02H9/04
Filed: 1990-02-22
Abstract: PURPOSE:To make it possible to continue subscriber service even after occurrence of surge by a method wherein a protecting element of which a switching circuit is not broken down is connected to a subscriber's line when it is detected by a breakdown detecting means that another protecting element connected to a subscriber's line is broken down by the surge. CONSTITUTION:When surge occurs, a varistor 15 is broken down and thereby a telephone set 10 and a subscriber's circuit 12 are protected. When the varistor 15 is short-circuited by the breakdown, energization of a relay coil 32 is stopped. Therefore a movable point (c) of a relay switch 31 is connected to a contact (b) and a varistor 30 is connected between subscriber's lines 11a and 11b. Concurrently, a surge detection signal is generated and sent to a personal computer. According to this information, an instruction on replacement of the varistor 15 is given by maintenance personnel in a station. Surge protection is continued by the varistor 30 until the varistor 15 is replaced.

IPC: H01F41/02
Filed: 1994-03-14
Abstract: PURPOSE:To control a metallic sheet winding device by eliminating the influence of the deflection and expansion of a winding belt and without causing vibrations. CONSTITUTION:When a steel sheet is wound around a winding shaft by moving a winding belt 18 by means of a servo motor 22, the motor 22 is controlled based on the difference between the number of pulses outputted from a pulse generator 24 which detects the rotation of the motor 22 and the number of speed commanding pulses during the period from the time when the winding of the steel sheet is started to the time immediately before the completion of the winding. As a result, the rotation of the motor 22 can be controlled in such a state that the influence of the deflection and expansion of the belt 18 is eliminated. When the winding of the steel sheet is about to be completed, the rotation of the motor 22 is controlled based on the difference between the number of pulses outputted from another pulse generator 28 which detects the moving amount of the belt 18 and the number of position commanding pulses.

Title: Shape measuring apparatus
Inventor: IWAMOTO YOJIRO
IPC: G01B11/24
Filed: 1986-02-27
Abstract: PURPOSE:To realize a highly accurate shape measuring apparatus, by dividing laser beam into two by a beam splitter to form interference fringes different in a phase after the reference beam from a reference plane anda the beam to be referred to from a surface to be measured are superposed. CONSTITUTION:The laser beam emitted from He-Ne laser 30 are linear polarized beams inclined at an angle of 45 deg. to the optical axis of lambda/4 plates 21, 32. These laser beams pass through the lambda/4 plate 32 to be synthesized in to beam in phase relation in two directions crossing at a right angle and the synthesized beam is projected to a beam splitter 1 to be separated into reflected beams and transmitted beams. The transmitted beams impinge against a surface 3 to be measured to be reflected therefrom and the reflected beams are projected to the lambda/4 plate 21 but impinge against a reference plane 2 to be reflected therefrom and superposed by the beam splitter 1 to become interference beam. The interference fringe obtained by a circular polarizing plate 33 is condensed by an imaging lens 34 to be formed into an image on an area sensor 35 to generate an electric signal corresponding to the quantity of beams at every beam receiving element unit. Because the effect of the shape error of the lambda/4 plate in the beam path of reference beam is not generated in phase change, the measurement of a shape can be performed with high accuracy.

CONSTITUTION:A check region is set basing on the previously set check region data, and the height of a board level check point is measured to obtain the height H0 of a board. In succession, a previously set offset height d is added to H0 for obtaining cross-sectional area, and a cross-sectional binary-coded image at the height is obtained. The area of the binary-coded part is obtained, and the area concerned is substituted for A. The envelope of the binary-coded part is obtained, the area of a part inside the envelope is calculated, and the area is substituted for B. A is subtracted from B, whereby the area of a hole and a recess is obtained, and the area is compared with a check standard. If the area is larger than the check standard, it is judged that a hole and a recess are present, a soldered part is judged that it has a hole or a blow-hole, then the solder part is judged defective.
