Abstract: A sheet-shaped check valve 23 which opens and closes the injection passage 21 is placed in the check valve chamber 22, an injection discharge passage 21b portion connected to the compression chamber 13 of the injection passage 21 and the check valve chamber 22 open from an outer surface of the fixed scroll 11, a lid body 25 is attached to openings of the injection discharge passage 21b and the check valve chamber 22 such that the check valve 23 is sandwiched between the openings and the lid body 25, and the injection discharge passage 21b and the check valve chamber 22 are hermetically closed, thereby forming the injection passage 21. According to this, it is possible to provide a reliable, efficient and inexpensive compressor with an injection mechanism.

Abstract: A compressor includes: a fixed scroll; at least one discharge port; a reed valve; a valve stop; and a ventilation hole. The at least one discharge port is disposed in the fixed scroll. The reed valve is disposed in the fixed scroll so as to block the at least one discharge port. The valve stop is disposed in the fixed scroll, and restricts the lift amount of the reed valve. The ventilation hole is disposed in the valve stop. In the present aspect, the flow of refrigerant gas is smoothed to suppress the compression loss, and the force applied to the reed valve can be suppressed. As a result, the efficiency and reliability can be improved.

Abstract: A compressor includes fixed scroll (6) and revolving scroll (7) configuring compression mechanism (2), compression chamber (9), intake chamber (11), discharge port (12), muffler (16), and heat-insulating member (24) provided between fixed scroll (6) and muffler (16). After a refrigerant gas taken into intake chamber (11) is compressed by revolving scroll (7) revolving and compression chamber (9) moving while changing a volume of compression chamber (9), the refrigerant gas is discharged from discharge port (12). The refrigerant gas discharged from discharge port (12) is discharged into muffler space (14) formed by muffler (16). Heat-insulating member (24) includes heat-insulating member discharge port (25), lead valve (13), and recess (27).

Abstract: Provided is a compressor including fixed scroll (6) and revolving scroll (7) configuring compression mechanism (2), compression chamber (9) formed between fixed scroll (6) and revolving scroll (7), intake chamber (11) provided on an outer circumferential side of fixed scroll (6), discharge port (12) provided in a central part of fixed scroll (6), muffler (16) provided to cover discharge port (12) at an upper part of fixed scroll (6), and heat-insulating member (24) provided between fixed scroll (6) and muffler space (14) formed by muffler (16). After a refrigerant gas taken into intake chamber (11) is compressed by revolving scroll (7) revolving and compression chamber (9) moving while changing a volume of compression chamber (9), the refrigerant gas is discharged from discharge port (12). The refrigerant gas discharged from discharge port (12) is discharged into muffler space (14).

Abstract: A solid-state imaging device includes: a pixel array including a plurality of pixel circuits arranged in rows and columns; a vertical signal line that is provided for each of the columns and transmits pixel signals; a column AD circuit that is provided for each of the columns and AD converts the pixel signals from the vertical signal line; a column-switching circuit that is interposed in the vertical signal line between the pixel array and the column AD circuit and switches connection between the vertical signal line and the column AD circuit; a controller that causes the column-switching circuit to switch the connection for every horizontal scan period; and a restoration circuit that restores ordering of the AD converted signals so as to correspond to ordering in which the vertical signal lines are arranged in the pixel array.

Abstract: Once it is determined in Step S2 that a corner has been detected, a control unit causes a body to perform a reciprocating motion and initiate corner cleaning in Step S3. Then, once it is determined in Step S4 that a rubbish detection sensor detects no rubbish, the corner cleaning is terminated in Step S6. Once it is determined in Step S4 that the rubbish detection sensor detects rubbish, the corner cleaning continues to be executed by the body being caused to perform the reciprocating motion in Step S5. In other words, an autonomous travel-type cleaner is realized that can remove a large amount of the rubbish accumulating at the corner by causing the body to perform the reciprocating motion.
