A contents providing system includes a communication unit, a print control unit, an expendable amount deriving unit and an expendable amount storing control unit. The communication unit communicates with a contents server having contents data. The print control unit controls a printer to print the contents data and output a printed material imaging the contents data if the communication unit receives the contents data from the contents server. The expendable amount deriving unit derives an amount of an expendable item required for imaging the contents data in the printer. The expendable amount deriving unit derives the amount of the expendable item in accordance with a size of an image printed by the printer. The expendable amount storing control unit stores information representing the amount of the expendable item derived by the expendable amount deriving unit in a memory unit.

An information management system is provided, which includes: an external device having an output unit that performs a predetermined process; an information processing device connected to the external device; and a second storage unit that stores utilization data, which is accessed by the external device and the information processing device. When a first period in which the utilization data is utilized by the utilization unit and a second period in which target data of the output unit is previously utilized overlap with each other, the utilization data correlated with the first period is correlated with the target data output in the second period.

A flexible printed circuit board that electrically connects a main body and a rotary body to each other is twisted in advance through an angle that is a half of an angle of rotation through which the rotary body is rotated. One end of the flexible printed circuit board is fixed to the main body, and the other end thereof is fixed to the rotary body. The rotary body is rotated in a direction causing the twist of the flexible printed circuit board to diminish.

A reciprocating compressor includes a front-side delivery chamber 18a formed at a front-side cylinder head 6, a rear-side delivery chamber 18b formed at a rear-side cylinder head 8, a plurality of delivery passages 12a and 12b formed at cylinder blocks 2 and 4 and an outlet port 16 that communicates between one of the delivery passages and an external circuit. The other delivery passage 12b that is not in communication with the outlet port 16 is made to communicate with the front-side delivery chamber 18a and the rear-side delivery chamber 18b and is also made to communicate with the delivery passage 12a in communication with the outlet port 16 via a guide passage 17. The delivery passage 12a in communication with the outlet port 16 is made to communicate with either the front-side delivery chamber or the rear-side delivery chamber via a constricted portion 40 having a passage section smaller than the passage sections at positions at which the other delivery passage 12b communicates with the delivery chambers 18a and 18b, and the dimensions of the constricted portion are set so that its area is equal to or smaller than the area of a circular section with a diameter of 1.5 mm. The reciprocating compressor adopting the structure described above makes it possible to reduce the extent of discharge pulsation and ultimately reduce vibration and noise.

Systems and methods of measuring optical pulses are described. In one aspect, an optical pulse measurement system includes an optical signal divider and an optical signal conversion system. The optical signal divider has an optical input for receiving an input optical signal, multiple optical outputs, and a set of multiple optical channels. The optical channels are coupled between the optical input and respective optical outputs and are operable to delay propagation of optical signals, which are divided from the input optical signal, from the optical input to respective optical outputs by different respective amounts of time. The optical signal conversion system is coupled to the optical signal divider optical outputs and is operable to convert temporal intensity distributions of light received from the optical signal divider optical outputs into respective spatial intensity distributions in parallel.
