An improved control circuit for a commercial automatic ice cube maker of the type wherein a slab of ice is formed on a freezing plate by flowing water thereover. The circuit provides a more uniform control means that is independent of atmospheric pressure effects by means of a mercury ice thickness control thermostat switch connected between the base and emitter of a transistor, such that upon sensing a predetermined temperature of the built up ice slab the thermostatic switch opens to cause the...

An ice maker control circuit for use with an ice maker of the type including an inclined refrigerated plate which is energized during a slab formation cycle during which water is continually circulated across the inclined refrigerated plate and wherein ice slabs released from the plate are directed to a cutting grid for melting the slab into a plurality of cubes of ice; the control circuit including a pair of ice thickness sensing thermostats each being associated with a transistorized control s...

An invalid carriage including a chair of pivotted construction with a connection between the back of the chair and a mast that is fixed to a chassis. There are means to raise the connection up the mast, so raising the chair seat from horizontal to forwardly-sloping so as to help raise a user of the chair from a sitting to a standing position, and to lower the connection so that the reverse occurs so as to help a standing person to sit down in the chair. As the mast connection moves, so collapsin...

Piezo-electric assembly having a piezo-electric resonator of trapped energy type assembled within a forming case. A bulkhead within the case prevents manufacturing defects due to internal spreading of conductive paste, regardless of variations in the coating amount of the conductive paste in mass production or variations in the mount pressure. Constant clearance exists between the internal connecting portions of the external terminals and the draw-out electrode (input/output) electrodes of the r...

In the present ice making apparatus a screw type extruder advances the slush toward an apertured extrusion plate. The extruder axle extends with its upper end through the extrusion plate. Air vents, for example, in the form of a ring gap between the extruder axle and the extrusion plate, are provided for venting the space below the extrusion plate. A water circulation circuit including a water space adjacent to said vent or vents provides for a heat exchange between the circulating water and the...

A water distributor and an ice cutter for a tube-ice machine includes a water distributor having a cylindrical body, a multiangle head having two opposite spiraling water passageways and an air tube. Each of the water passageways are in fluid communication with the hollow interior of the multi-angle head to permit water to enter therethrough into one of a plurality of ice making tubes, to be frozen into a long bar of ice. Subsequently, the periphery of the bar of ice is melted to cause it to fal...

A piezoelectric oscillator containing load capacitances utilizing the thickness shear vibration mode of a piezoelectric plate. In this piezoelectric oscillator, a pair of divided electrodes are formed on one major surface of a piezoelectric plate and are divided by a gap provided in a direction extending from one end surface to the other end surface of the piezoelectric plate, and the pair of divided electrodes are formed so as to be opposed to a common electrode formed on the other major surfac...

A piezoelectric resonant component is constructed such that it is possible to reduce the thickness of an exterior case member while preventing fracture and chipping of the exterior case member. The piezoelectric resonant component preferably includes exterior substrates defining exterior case members and being stacked on an energy trap type piezoelectric resonant element via adhesive layers disposed therebetween so as to define spaces for allowing for free and unhindered vibration of the piezoel...

An image pickup element drive control method can outputs a sharp image effectively without producing any overlapped images when it is driven for a high rate image pickup operation. In a high rate image pickup operation using an interline transfer type solid state image pickup element having a light receiving section of a plurality of light receiving elements arranged in the form of a matrix and adapted to accumulate respective electric charges representing the received quantity of light, a verti...
