Abstract: This invention relates to a body height and weight measuring machine, which operates by means of a winding transmission cord means to drive a sliding plate having sensing, measuring, and digital display functions. When the sliding plate moving upwards, the sensing means will receive the refracted infrared rays as a result of a person's height to cause said winding transmission cord means to stop moving; then, a correct height and weight will be displayed thru digital display means. The aforesaid height measurement and its digital display are done by means of a photocell sensing means being coupled to a scale plate that includes a black and transparent strip in alternate arrangement and equal width so as to have said photocell sensing means generating a forward or reverse sequence sensing signal during the sliding plate moving; then, said signals will be shown on a display means driven with driving circuit.

Abstract: Method and apparatus for forming a photographic record representing acoustic characteristics of a sound field such as the distribution of sound pressure and the distribution of equiphase surface wave are disclosed. A microphone and a light emitting diode are reciprocally moved to scan a plane in the sound field and an envelope signal of an output signal from the microphone is derived. The envelope signal is then sampled at a given sampling frequency to produce a sample signal. A carrier having a given frequency is amplitude-modulated with the sample signal to derive a modulated signal. Then, a switching circuit is controlled by the modulated signal in such a manner that when the envelope signal exceeds a predetermined value, the switching circuit is made on and off repeatedly and thus the light emitting diode is turned on and off at a rate of the carrier frequency to form a locas of the light spot. An image of the locus of the light spot is recorded optically on a photographic film.

Abstract: An integral multiswitch display panel (FIG. 3) having a plurality of pushbutton switches (A1-4, B1-4, C1-4, D1-4) mounted thereon along with a signal lamp (16) for each switch. A control circuitry P.C. board (44) and a display drive P.C. board (10) are common to all the switches with the control contacts (40, 42) of the switches controlling the displays (24) within the respective pushbuttons to provide on-off or alpha-numeric informational indications in response to operation of the bushbutton switches. The printed circuit lines of the control circuitry P.C. board (44) are connected through hermetically sealed connectors (50, 52, 54) at the bottom of the display panel to external controlled circuits with at least some of these lines being connected to the display drive P.C. board (10) for controlling the displays (24). The pushbuttons are environmentally sealed by a common seal (8) to prevent dirt, water, and the like from entering inside the panel housing (2, 4).

Abstract: A switch suitable for use in the remote control of electrically driven rearview mirrors of a motor vehicle. The switch is adapted to close and open a plurality of switch elements by means of a single or divided operation member. The switch occupies only a small space in an instrument panel, etc. of a motor vehicle because the switch is thin and small. Fixed contact pairs (3a, 4a) to (3f', 4f') forming fixed contact components are printed approximately point symmetrically around a specific center on an insulating base plate. Movable contact means is disposed on top of the fixed contact components, said movable contact means being adapted to electrically connect each of the fixed contact pairs (3a, 4a) to (3f', 4') when said means is pushed.

Abstract: A switch assembly is provided for mounting in the two-part housing of a joystick apparatus. The assembly includes a printed circuit board held between retainers on the two parts of the housing. A plurality of switches are mounted on the board, each including a fixed printed contact and a movable leaf spring contact, the leaf spring contacts being engageable with actuators on a tilt plate which is tiltably carried by the joystick handle for selective actuation of the switches. The board also carries a fire control switch including a printed contact and a leaf spring contact which is engageable with a push-button actuator on the joystick handle. The handle includes a support module therefor which is held in place by retaining pins on one of the two housing parts, the tilt plate having recesses therein for accommodating the retaining pins.

Abstract: A printer such as an ink jet printer in which a record carrier is fed around a transport roller and over an elongated flat supporting surface extending alongside the roller, with a printing head displaceable along that surface. To cause the carrier to lie flat under the printing head, the surface lies in a plane which is a secant plane with respect to the roller, the secant defining a roller circular segment having a height less than half the roller radius. Between the head and the roller, a ruler presses the record carrier toward but not against the flat surface at that location, causing the carrier to lie flat under the printing head.

Abstract: Slots are provided in at least one wall or surface common to the weighing chamber and the chamber housing the weighing mechanism. These slots are located so that air currents streaming through them will not affect the weighing dish and thereby the measured results. The slots are preferably located in the bottom near the front wall or the rear wall of the weighing chamber. The air currents can then effect rapid temperature and pressure compensation.
