Abstract: An improved voltage reference circuit is provided comprising a series combination of a Kelvin-connected buried zener diode and a transistor.

Abstract: A solar collector is provided having a substantially triangular-shaped housing defined by a base and a pair of converging side walls. The housing of the collector includes an outlet adjacent the top of the housing, an inlet, a central area and a pair of outer end areas. The problem of stagnation of air in the outer end areas is solved by providing barrier means adjacent the side walls for creating air ducts connecting the outer end areas to the outlet. The intake air is distributed along the base of the collector by an inverted T-shaped air distributor means.

Abstract: A loop controller transmits data to and receives data from a plurality of I/O ports on a TDM serial loop by generating a plurality of frames which include a frame control field followed by a plurality of dedicated time slot fields. Each time slot field includes an inbound data control bit or bits followed by a data field followed by an outbound data control bit or bits. The I/O port inputs and outputs data in its dedicated data field as dictated by the respective data control bit. The loop controller and I/O ports monitor the data control bit to request data, indicate insertion of data, indicate receipt of the data and acknowledge the receipt indication to achieve a complete handshake. During an initialization frame, the I/O ports set themselves into primary and secondary data modes based on sensing a prior I/O port with the same dedicated time slot.

Abstract: In a molding composed of a molding body comprising a front surface, a bottom, a side portion and a hollow portion, and of an adhesive layer constituted at the bottom, the thin molding side portion extends along the front surface, and the bottom is provided with a projection which projects on one side or both sides of the bottom separate from the front surface and the molding side portion. When the front surface is pushed, the pushing force applied to the front surface produces the fulcrum of the bending moment at the molding side portion and the plane pressure from the fulcrum to the front surface in the direction towards the inside of the bottom, and at the same time the contact pressure applied to the point of action of force is distributed in the plane pressure distribution towards the front surface which attenuates from the peak value below the point of action of force to both sides gradually.
