A swash plate type refrigerant compressor comprises a compressor housing enclosing therein a crank chamber, a suction chamber and a discharge chamber. A swash plate is tiltably connected to the drive shaft and has two sliding surfaces sides thereof. The swash plate includes a sliding surface which engages a plurality of pairs of shoes. The shoes couple the swash plate to the pistons so that the pistons may be driven in a reciprocating motion within the cylinder bores upon rotation of the swash plate. At least one groove is formed in the sliding contact surfaces between the swash plate and the shoes. The groove captures and retains lubricating oil in the refrigerant in response to the rotation of the swash plate.

An apparatus for conveying and aligning various types of film packages recovered for recycling. A conveyer of the apparatus is constructed by a pair of parallel belts combined to form a V-shaped bearing gutter and driven in the same conveying direction. The film packages are conveyed on the conveyer and are slid downward through an inclined cylindrical tube which rotates about the longitudinal axis and has spiral ridges on the inner periphery. Thereby, the longitudinal direction of the film packages are aligned with the conveying direction. Then a posture discriminator discriminates between the upright posture and the upside-down posture of the film packages on a first conveying path, based on the position of the viewfinder. The film packages having the upright posture are caused to fall headlong from the first conveying path onto a second conveying path, so as to have the upside-down posture on the second conveying path. The film packages conveyed on the first and second conveying paths are again joined together in a line.

An image processing device able to display an image in high quality in a color image display using fixed pixels, which drives a display device making pixels of R, G and B arranged inside each of a plurality of areas on a screen emit light to display a designated color in unit areas, wherein a signal generation circuit determines a pixel of which an arrangement position is not matched with a reference position of the unit area used for reference by a first pixel signal as a target to be interpolated among pixels of R, G and B, generates a second pixel signal which uses the arrangement position of the pixel to be interpolated as a reference on the basis of the first pixel signal.

A lens-fitted photographic film unit has a film supply chamber preloaded with unexposed photographic film. A cassette-containing chamber contains a film cassette. The film after exposure is wound on a spool of the cassette. The film unit is provided with a mechanism for exposing the film in a succession of frames. An axial hole is formed in an upper end of the spool. Knurled inner teeth are formed inside the axial hole. A wind-up wheel is mounted on the film unit over the cassette-containing chamber to be externally operable for rotation. A drive shaft on the wind-up wheel protrudes into the cassette-containing chamber, and is received in the axial hole. Knurled outer teeth about the drive shaft mesh with the inner teeth on the spool. The drive shaft and spool will thus mesh with each other in any relatively rotated position thereof, which avoids loss of usable film.

A deflection current circuit having reduced power requirements. A switch 33 is controlled by a control circuit 71 in association with the horizontal deflection period. A switch 73 is controlled by the control circuit 72 in synchronization with the horizontal deflection period modulated by the vertical deflection period. Switch 33 is turned off in the retrace interval, and during the period in which the switch 33 is in the off-state, the switch 73 is turned off for a predetermined period. The off-period of the switch 73 is modulated by the vertical deflection period to produce greater horizontal deflection in the center of the screen.

After exposure of all frames of a film contained in a lens-fitted photographic film, a wall portion of a film take-up chamber of the film package is removed, thereby to provide a film removal opening, through which the exposed film is drawn out directly from the film package. In the film take-up chamber, a cassette or a take-up spool is disposed for winding up the exposed film. So as not completely to wind the exposed film into the cassette, a film arresting member is provided. A film package holder disposed at a film entrance of a film processor can selectively hold the film package or a film cassette taken out from a camera.

A piston type compressor includes a compressor housing enclosing a crank chamber, a suction chamber, and a discharge chamber therein. The compressor housing comprises a cylinder block having a plurality of cylinders. A drive shaft is rotatably supported in the cylinder block. A plate is tiltably connected to the drive shaft and is coupled to a plurality of pistons which may be driven in a reciprocating motion within the cylinders upon rotation of the drive shaft. Each of the pistons is provided with a rotation prevention mechanism which may include a first rotation prevention device formed on the center of the piston and second rotation prevention device disposed within the compressor housing, the first and second rotation prevention devices cooperating to prevent the piston from rotating about its own axis. The first and second rotation prevention devices each have at least one sliding surface formed thereon. Further, the rotation prevention mechanism may include a rotation prevention device formed on a center of the piston, the rotation prevention device including at least two sliding surfaces formed on both radial sides of the piston, each sliding surface smoothly sliding on an adjacent sliding surface of an adjacent rotation prevention device so that the rotation prevention device and the adjacent rotation prevention device cooperate to prevent the piston from rotating about its own axis. The sliding surfaces of the rotation prevention mechanism may be formed to be fine surfaces by machining in a finishing process.

In order to display a video signal having an aspect ratio of 4 to 3 on a video display screen having a 16 to 9 aspect ratio a nonlinear vertical deflection signal is used to compress the video image along the top and bottom edges of the 16 to 9 aspect ratio screen. The video image is compressed only along the top and bottom edges of the screen because it has been found that motion of the point of view of the viewer relative to the displayed image is generally horizontal but is infrequently vertical. One approach to providing the non-linear vertical deflection waveform is to detect whether the input video signal for display on a 16 to 9 aspect ratio screen is a 4 to 3 aspect ratio signal and, if so, to read out special, non-linear data from a memory. This special waveform data is used to generate the non-linear vertical deflection waveform. If the input video signal is detected to be a 16 to 9 aspect ratio signal, standard data is read out from the memory to be used to generate the appropriate linear vertical deflection waveform.

An image processing device for displaying an image in high quality on color image display using fixed pixels. The image processing device causes a display device making pixels of R, G and B arranged inside each of a plurality of areas on a screen emit light to display a designated color in unit areas. A signal generation circuit determines a pixel of which an arrangement position is not matched with a reference position of the unit area used for reference by a first pixel signal as a target to be interpolated among pixels of R, G and B, generates a second pixel signal which uses the arrangement position of the pixel to be interpolated as a reference on the basis of the first pixel signal.
