To provide a heat pump apparatus, such as a heat pump water heating apparatus, capable of efficiently supplying high-temperature water by increasing a condensation capacity to a maximum if the outside air temperature is low. The heat pump water heating apparatus is configured to include a first refrigeration cycle and a second refrigeration cycle. The first refrigeration cycle is configured to connect in series a main compressor, a first water-refrigerant heat exchanger, an internal heat exchanger, a first pressure reducing device, and an air heat exchanger. The second refrigeration cycle diverges from the first refrigeration cycle between the first water-refrigerant heat exchanger and the first pressure reducing device, and joins the first refrigeration cycle between the main compressor and the first water-refrigerant heat exchanger. The second refrigeration cycle is configured to connect in series a second pressure reducing device, an internal heat exchanger, a sub compressor, and a third pressure reducing device

The present invention provides a system to ensure security of data in a computer network system. A center certifies a public-key of user of the system and distributes a secret-key. A first system comprises the center in a network, an information provider and a plurality of users. The center identifies utilization status by requests of the secret-key. The data is encrypted by the secret-key and is stored and transferred, while the data to be stored and transferred is encrypted by a secret-key different from the secret-key of the transferred data. An original data label is added to the original data, and an edit label is added to the edited data, and the center does not store the data and stores only the original data label and the edit label. A second system comprises a center and an information provider in a network, and a plurality of users utilizing the network. The center stores the original data and editing scenario, and also the original data label, user label and edit label. The data is not transferred between the users, but data label encrypted by the public-key is transferred. In electronic commerce system, every data is distributed through a mediator in the network, data which is transferred from a maker to a user is encrypted by a secret-key for encryption, and data which is transferred from the user to the maker is encrypted by a secret-key for re-encryption.

An armrest, has a stationary shaft rotatably supporting an armrest body against a seat frame. The stationary shaft is inserted, so as to have fastening tolerance, inside a coil lock spring and to have a stationary-side hook and a free-side hook. A diameter of the coil lock spring is reduced or enlarged according to a normal or a reverse rotation, respectively, of the armrest body, so as to prevent or permit, respectively, the rotation of the armrest body. One of the inside diameter of the lock spring and the outside diameter of the stationary shaft is tapered in said shaft's axial direction.

If the number of frames in a GOP of an input stream is not less than 15, the GOP is determined as a control unit time. If the number of frames in the GOP is less than 15, the following GOP is connected thereto until the number of frames becomes not less than 15 and the connected GOPs are determined as a control unit time. After correcting the control unit time, the average input bit rate Sn in each control unit time is obtained, and by using information on the input stream including the average input bit rate Sn, a quantization step value of an output stream is calculated.

An optical modulator has, on a substrate having electro-optic effect, an optical waveguide including an input optical waveguide, two branching optical waveguides which branch a light beam incident to the input optical waveguide into two beams, two interaction optical waveguides which modulate a light beam phase by applying a voltage between a center electrode and ground electrodes, a multiplexing optical waveguide which multiplexes the light beams which propagate through the two interaction optical waveguides, and an output optical waveguide which is connected to the multiplexing optical waveguide through a multiplexing point. In the optical modulator, a high-order mode light beam which is generated by multiplexing the phase-modulated light beam and which is radiated from the multiplexing point to an inside of the substrate as two radiant light beams while the high-order mode light beam hardly propagates through the output optical waveguide, and at least one of the two radiant light beams is detected by a monitor photodetector. The output optical waveguide is formed while deformed in order to secure a space for mounting the monitor photodetector such that at least one of optical axes of the radiant light beams in a substrate end portion located on the output optical waveguide and an end of the output optical waveguide are separated from each other by a predetermined distance.
