摘要:
An analog-to-digital converter arranged to accept an analog input signal and to convert it into an output having digital form. The converter is characterized by a reference random noise source which generates random noise signals with uniform amplitude occurrence probability density in a given range, and by an amplitude comparator arranged to repeatedly compare the amplitude of the random noise signal with the amplitude of a signal varying with the analog signal to be converted. The amplitude comparator supplies output pulses in accordance with the comparisons, e.g., whenever the analog signal amplitude is greater than the random noise amplitude, and the number of pulses from the amplitude comparator in a measurement interval then digitally corresponds to the value of the analog signal and may be utilized, as in a display. Resolution of the converter is increased beyond the minimum amplitude increment of the random noise source signal in one embodiment by superposition on either the analog signal or the random noise signal of a triangular wave with an amplitude greater than the minimum amplitude increment of the random noise signal, and in another embodiment by superposition of a second random noise signal.

A printing device includes a printing unit that prints a print-object image corresponding to print data on a recording medium. A placing unit places restriction information on the recording medium if the print data is attached with the first restriction condition. The restriction information is used for attaching a second restriction condition to scanned data that is generated by reading the print-object image printed on the recording medium. The second restriction condition is for placing restrictions on the usage of the scanned data.

A heat pump apparatus includes: a refrigerant circuit which includes a compressor, an utilization-side heat exchanger, a first expansion valve, and an outdoor heat exchanger; an injection pipe which includes a solenoid switching valve and a second expansion valve; and an objective supercooling degree table which stores objective supercooling degrees according to condensing pressure in the refrigerant circuit and rotation number of the compressor. In the heat pump apparatus, liquid refrigerant is injected to the compressor by way of the injection pipe. The heat pump apparatus switches between a first case where the liquid refrigerant is injected to the compressor and a second case where the liquid refrigerant is not injected, and a value of the objective supercooling degree is changed between the first case and the second case to control the first expansion valve based on the value of the objective supercooling degree.

A light source device can include a solid-state light source configured to emit blue light as excitation light and a phosphor section which is excited by the excitation light from the solid-state light source and which emits fluorescent light longer in wavelength than the light emitted from the solid-state light source. In the light source device, a wavelength selective member configured to transmit the excitation light from the solid-state light source and to reflect the fluorescent light from the phosphor section can be provided between the phosphor section and the solid-state light source. The size of the wavelength selective member can be less than the size of the phosphor section which can be greater than the size of the excitation light spot irradiated with the solid-state light source.

A print system provided with an information processor and a printer communicably connected to the information processor. The information processor comprises a transmit section for transmitting a plural sets of print data. The printer comprises a receiving section for receiving the print data transmitted from the transmit section; a storage section for storing the print data received by the receiving section; a printing section for printing the print data stored in the storage section; a determination section for determining whether the printing by the printing section is completed or not; and a control section for controlling the printing section not to print the print data transmitted as the second set when the printing of the print data transmitted as the first set is completed, and to print the print data transmitted as the second set when the printing of the print data transmitted as the first set.

A reflector array optical device includes two dihedral corner reflector array optical elements each having a substrate and a plurality of prism bodies arranged regularly on and each protruding from one main surface of the substrate. Each prism body includes at least two sides of orthogonal planes. The two optical elements are adhered so that top faces of the prism bodies are directly confronted respectively so as to make two coplanar planes in which the two orthogonal planes exist respectively.

A vertically aligned liquid crystal cell to be simple-matrix driven is disposed between two polarizing plates crossed-Nicol disposed, the liquid crystal cell including a liquid crystal layer having a retardation in a cross section in a thickness direction larger than 550 nm. A C plate and a biaxial plate are disposed collectively between the liquid crystal cell and one of the polarizing plates, the C plate being disposed on the liquid crystal cell side and the biaxial plate being disposed on the polarizing plate side. The biaxial plate is disposed in such a manner that the in-plane delay phase axis of the biaxial plate is perpendicular to the absorption axis of the adjacent polarizing plate.
