Abstract: A coil collecting apparatus including a coin container defining a receiver housing. The housing is designed to receive a coin box taken from a parking meter or vending apparatus, and the box defines a closure which opens when the box is received in the housing and rotated. The housing defines a passage adapted to register with the coin box opening upon such rotation whereby the coins in the box can be discharged into the coin container. A cover is provided for the receiver housing, and the cover carries a coin box engaging head which engages the box when it is located in the housing and when the cover has been closed. A rotatable cover handle is provided for rotating the head and the engaged box. A locking bar is operatively connected to the cover, and this bar interfits with a blocking sleeve located within the receiver housing to hold the blocking sleeve in blocking position when the cover is open and until the cover is closed.

Abstract: Disclosed is a window antenna for a vehicle wherein a pair of semiloop antenna elements having a length of .lambda./2 are branched from a power feed point along a grounded conductor portion in the vertical direction, their terminals are grounded, and the feed point is unbalanced power fed. The antenna has good transmission/reception characteristics in UHF band.

Abstract: A fluid pressure control apparatus for a vehicle includes: an inlet port connected to a master cylinder; an outlet port connected to a wheel cylinder of a brake apparatus for a front wheel; a valve apparatus arranged in a path connecting the inlet and outlet ports; a movable plunger for closing and opening the valve apparatus, receiving fluid pressures at both sides; a first spring for urging the plunger in the direction to open the valve apparatus; an electromagnetic coil to be energized by a signal transmitted on the basis of the driver's operation for driving the vehicle backwards; the valve apparatus including a valve body which can be separated from and slated on a valve seat formed on the plunger; a second spring for urging the valve body to the first position where the valve body cannot contact with the valve seat of the plunger in spite of movement of the plunger; and the valve body being moved by energization of the electromagnetic coil to the second position where the valve body can contact with the

Abstract: A foundation for a retaining wall-type of structure acted upon by a principal force tending to slide same in a predetermined direction is anchored by a plurality of slide resisting walls. The slide resisting walls extend parallel to the predetermined direction in which the foundation tends to slide. The upper portions of the slide resisting walls are embedded in a concrete mass. The lower portions of the slide resisting walls project downwardly from the concrete mass into the earth, and are solely in engagement with the earth and not with concrete.

Abstract: A pull-type booster for a vehicle includes a main body having an internal space; a movable body including a head portion and a cylindrical portion formed integrally with the head portion, the head portion being arranged in the internal space and partitioning the internal space into a lower pressure chamber at one side and a control chamber at another side, and the cylindrical portion projecting from the main body at the other side; a through hole formed in the movable body; a pull input rod extending across the low pressure chamber and projecting through a seal member from the main body at the one side; a plunger arranged slidably in the through hole and combined with a head portion of the pull input rod; a valve member arranged in the through hole and operated by the plunger for generating pressure difference between the lower pressure chamber and the control chamber and moving the movable body in the direction of the lower pressure chamber, a power transmission assembly arranged in an opening end portion of

Abstract: A cleaning and disinfecting article of manufacture and method are provided wherein the cleaning and disinfecting article of manufacture comprises a cleaning and disinfecting ingredient which includes a cleaning and disinfecting agent, a solid color indicator composition which includes a color indicator agent and a matrix agent supporting the color indicator agent, wherein the matrix agent is a matrix salt; and a stabilizing salt. The cleaning and disinfecting ingredient has a bleaching tendency relative to the color indicator agent such that when the solid color indicator composition is in an aqueous solution of the cleaning and disinfecting ingredient, the presence of the cleaning and disinfecting ingredient in the solution minimizes the display of color in the solution for as long as significant amounts of the cleaning and disinfecting ingredient are present.

Abstract: A one-joint type horizontal pivot arm is adopted as contour tracing mechanism for controlling the position of a grinding unit along a contour of a plate material. The grinding unit is attached to a distal end of the pivot arm and is position-controlled by angular controls about a first axis at a base of the arm and about a second axis at a joint of the arm. A third axis is provided to the end of the pivot arm for facing the grinding unit in the direction normal to the end face. A pressure device is provided for urging the grinding unit against the end face. The position, facing direction and pressure of the grinding unit are controlled with preset teaching data sampled by tracing a model type to be end-face ground.

Abstract: In a linear pulse motor which includes: a movable body having an iron core provided with a coil or coils and side plates for supporting the iron core; a stationary body having magnetic circuit forming means for forming a magnetic circuit with the iron core across an air gap between the iron core and the magnetic circuit forming means; an axle fixed to the movable body, and wheels supported rotatably on end portions of the axle, respectively, and rollable on and along the stationary body; wherein the coil or coils are energized by pulses of a predetermined drive frequency to impart a stepwise magnetic drive force to the movable body, the length of the axle between the wheels is so determined that a noise level peak frequency or resonant frequency of the movable body is sufficiently far from the predetermined drive frequency.

Abstract: A plasma glow tube for displaying a bar of selectable length comprises an insulating enclosure filled with an ionizable gas. The enclosure may have flat opposing sides, the inside walls of which have conductive electrodes (preferably transparent) deposited thereover in a staggered pattern such that each electrode, except the end ones, is positioned between and equidistant from two opposing electrodes. The electrodes, except for the first and last electrodes which are DC coupled to the gas, are all covered with an insulating layer so that they are insulated from the gas. A potential difference, preferably in the form of a pulse, is applied between first and second end electrodes to ionize the gas therebetween and leave an inside wall charge adjacent said second electrode. A pulse is applied between the charged electrode and the next succeeding, opposite (third) electrode to ionize the gas therebetween and leave a charge on the third electrode, and so on.
