Abstract: A back massage device having spaced mounts on one side of a base and a fastening means, e.g. adhesive tapes or the hook-strips of the VELCRO, on the other side. The device has no moving parts, is small, and can be used at home, in office, or in a car. The user just installs the device on a generally vertical surface, like a wall or a chair back, and rubs his/her back against the mounts while sitting or standing to achieve the massaging effects.

Abstract: The connector assembly includes a housing that carries a flexible circuit member and two slide members with slide cam surfaces. A daughter board is secured to one surface on the housing and is electrically connected to the flexible circuit member. The cam surfaces on the two slide members engage cams on a mother board. Movement of the slide member cam surfaces relative to the cams on the mother board moves the housing relative to the mother board and forms an electrical connection between the flexible circuit member and the mother board. A linkage system moves both slide members to form and maintain the electrical connection between the flexible circuit member and the mother board.

Abstract: A connection system requiring little or no force to mechanically and electrically connect a printed circuit board to a flexible printed circuit. The connection system includes a flat and rigid carrier having an upper surface upon which is affixed a flexible printed circuit having an electrically conductive raised area in the form of a plurality of raised dots. At the upper surface, the carrier has a groove formed therein, wherein the raised dots are located in the groove. An elastomeric insert is situated in the groove in abutting relation to the flexible printed circuit behind the raised dots. A rigid printed circuit board has an electrically conductive area in the form of a plurality of pads. The printed circuit board is inserted into the groove, whereupon the elastomer resiliently compresses so as to press the plurality of raised dots into tight electrical contact with the plurality of pads. In a first preferred embodiment the printed circuit board is inserted vertically with slight force.

Abstract: A clamping mechanism (10) for connecting a printed circuit board (12) having a plurality of electrically conductive pads (14) to a flexible printed circuit having a plurality of electrically conductive raised dots (18). A housing (20) having a mouth (22) is located upon the printed circuit board at the plurality of pads. A pair of L-shaped leaf springs (28, 28') are connected with the housing. A cam body (40) having a rounded cam surface (42), an opposite grasping lever (44), and a pair of opposing first and second flat surfaces (46, 48) therebetween is rotatably connected to the leaf springs. A first stiffener (58) is attached to the flexible printed circuit opposite the raised dots thereof which is configured to alignably fit with the shape of the mouth of the housing to thereby align the raised dots with the pads. A second stiffener (54) is provided at the printed circuit board opposite the housing.

Abstract: This patent discloses the composition of germanate glass and a new method for its fabrication. The composition comprises germanate, the oxide of an alkali earth group, Al.sub.2 O.sub.3, ZnO, a halides compound eg. CaF.sub.2, CaCl.sub.2 and so on,, and can combine with a series of oxygenous compounds such as silicate, borate, phosphate, arsenate, tellurate and so on, if required. The addition of an alkali oxide could increase the glass formation rate and homogeneity, and the defects of devitrification, cord, knot, and blister are reduced. Its fabricated methods which consist of the reduction pressure melting with the addition of a halide and the drying procedure. The germanate glass body that is made is colorless and transparent and it can increase the transmittance of infrared from 20% to greater than 60% in the wave length 2.75-3.0 .mu.m. The price of producing the germanate glass is decreased and the transmittance of this composition system increased from 5% to 80%.

Abstract: The present invention relates to a tape winding tension control device which has at least one electromagnetic tension controller, a control circuit and at least one central processor, in which, the electromagnetic tension controller and control circuit in conjunction with the tape winding shaft form a cylinder shaft shape. There is an external electrode located on the exterior of the electromagnetic tension controller, and an inner ring electrode within. One microprocessor is located in every control circuit to stimulate the inner ring electrode by means of an output current. This allows an electromagnetic field to be formed to produce the rotating movement of the winding shaft, for providing the movement of the tape paper base. The central processor thus separately commands the tension of each microprocessor.
