Abstract: An air conditioner for an automotive vehicle having a water-cooling type internal combustion engine includes: a first refrigerator; and an adsorption type refrigerator having adsorbent. The first refrigerator controls temperature of air to be blown into a passenger compartment of the vehicle. The adsorbent generates adsorption heat when the adsorbent adsorbs the medium, and desorbs the adsorbed medium when the adsorbent is heated by coolant water in the internal combustion engine. The air to be blown into the passenger compartment is heated by the adsorption heat of the adsorbent, and is cooled by evaporation latent heat of the medium.

Abstract: An optical signal receiver producing an output signal from a received optical signal also generates two complementary signals from the output signal, integrates the two complementary signals, and takes the difference between the two integrated signals. The difference signal is used to control a bias current supplied to the input terminal of an amplifier that generates the output signal signal. Alternatively, the difference signal controls the gain of the amplifier. Output distortion is thereby corrected without requiring external adjustments.

Abstract: A differentiating circuit and a clock generating circuit that do not include unwanted frequency components in a differentiated signal. An inverted signal of an NRZ (Non Return Zero) data signal is delayed by a fixed time in a delay circuit and added to a non inverted signal to generate a differentiated signal. A clock signal is generated by driving a resonator using a rectified signal produced by full wave rectifying the differentiated signal. At this time, resonant components arising due to impedance mismatching are removed by providing a LPF.

Abstract: An optical transmitter has a Mach-Zehnder modulator, and a feedback loop that controls the bias voltage supplied to the modulator according to the insertion loss of the modulator, to compensate for DC drift in the attenuation characteristic of the modulator. The feedback loop can be switched to provide negative feedback on either the positive or negative slope of the attenuation characteristic. Switching the slope switches the polarity of the chirp generated by the modulator, enabling positive or negative chirp to be selected, whichever produces the least dispersion penalty. Since switching the slope also switches the polarity of the modulated signal, an optical transmission system using this optical transmitter has an additional circuit that selectively inverts the transmitted or received signal.

Abstract: A contact structure of a socket connector capable of shortening the arrangement pitch of socket contacts, and speeding up the processing cycle by simplifying the structure of a stamping die for the socket contacts. The socket contacts are formed by stamping an electrically conductive flat metal plate. Each socket contact is provided with a conductive section for taking on the contact with the other pin contact, a holding section to be press-fitted and fixed in an insulating housing, and a terminal section to be soldered on a circuit substrate.
