PROBLEM TO BE SOLVED: To provide a sliding door opening regulation device capable of reducing power consumption.SOLUTION: A sliding door opening regulation device according to the present invention prevents a sliding door 3A installed at an opening of a building from opening wider than a predetermined opening amount. A main unit 2 is attached to a case 1 set at the opening and a regulation member 4 is attached to the sliding door 3A. The main unit 2 comprises: a deadbolt 13; and a drive part 15 for moving the deadbolt 13. The deadbolt 13 is pressed to a flat cam 24 by a coil spring 14. A DC motor 16 of the drive part 15 operates to rotate a male screw member 23, which moves the flat cam 24 through a screw action. When the flat cam 24 moves, the deadbolt 13 protrudes to or retracts from the main unit 2. The regulation member 4 contacts the deadbolt 13 protruding from the main unit 2 to regulate the opening amount of the sliding door 3A.

PROBLEM TO BE SOLVED: To provide an electrotherapy apparatus capable of surely treating an affected part by substantially promoting activation of cells and tissues.SOLUTION: An electrotherapy apparatus includes: a rectifying/smoothing circuit 5 smoothing by rectifying an AC; and a probe 6 for outputting a DC obtained by rectifying/smoothing the AC by the rectifying/smoothing circuit 5. The probe 6 has a conductive contact part 7 and a conductive grip part 8, and the contact part 7 and the grip part 8 are isolated from each other. The grip part 8 of the probe 6 is connected with a positive electrode side of an output of the rectifying/smoothing circuit 5, and the contact part 7 of the probe 6 is connected with a negative electrode side of the output of the rectifying/smoothing circuit 5. In a state where the contact part 7 is brought into contact with a human body, with the person holding the grip part 8 of the probe 6, the DC flowing from the grip part 8 via the human body to the contact part 7 is adjusted to be 200 μA and a voltage between the grip part 8 and the contact part 7 is adjusted to be 70 V.

PROBLEM TO BE SOLVED: To provide a window opening/closing device capable of reducing burdens of a mechanism for opening/closing a sash and prolonging a service life.SOLUTION: The window opening/closing device includes: crossed arms 15 and 16 which swing with a spindle as a fulcrum; a right side opening/closing operation part 18 which swingably supports a proximal end part 15a of the arm 15; a left side opening/closing operation part 17 which swingably supports a proximal end part of the other arm 16; and a guide rod 19 which supports distal end parts of both the arms 15 and 16 slidably along a bottom rail of a sash 4. Both the arms 15 and 16 are swung in the direction that the proximal end parts and the distal end parts approach each other corresponding to the swing to the building outer side of the sash 4. For the right side opening/closing operation part 18, movement to the approaching direction is regulated by a wire rope 31. When a wind hits the sash 4 from the building outer side in the case that the sash 4 is open, the left side opening/closing operation part 17 is moved in the direction of separating from the right side opening/closing operation part 18 and the sash 4 is swung to the building inner side.

PROBLEM TO BE SOLVED: To provide a light-shielding screen device capable of performing different light-shielding from conventional one and forming a pattern on a window by a screen.SOLUTION: A light-shielding screen device is arranged in a square window 3 and includes a fan-shaped screen 10, a drum 11 of truncated cone shape for winding the screen 10, and a drive mechanism 12 for delivering the screen 10 from the drum 11. The drive mechanism 12 includes a support bar 16 mounted on the screen 10, a guide rail 18 of circular arc shape laid between adjacent sides of the window 3, a geared cable 17 connected to the support bar 16 via the guide rail 18 and a geared motor 20 for driving the geared cable 17. One end of the support bar 16 is extended up to a center point O of a circular arc forming a peripheral edge of the screen 10 and is oscillatably supported at the position of the center point O. The geared cable 17 is driven by the geared motor 20 to deliver the screen 10 from the drum 11.
