Abstract: A real-time image compression processor records on a CD or other recording media a compressed video signal which is compressively processed in a high recording efficiency at real-time as being reproduced by a VTR while preventing the image quality from being degraded. There are provided a first encoder for compressively encoding the video signal, and a second encoder for compressively encoding the signal obtainable by delaying such video signal for a given period of time. A parameter adjustment is executed for the second encoder in accordance with the compressed video signal obtained through the compressive encoding by the first encoder. The compressed video signal obtained by the second encoder is recorded on a recording medium.

Abstract: A piston for an internal combustion engine comprises at least a pair of ribs arranged between an inner surface portion of a skirt and side portions of pin bosses. The ribs are symmetrical with respect to a thrust center line of the piston and have in a longitudinal direction thereof a center line which is positioned to be lower than an axis of a piston pin.

Abstract: A piston skirt has narrowed relief sections adjacent piston bosses and between first and second relief sections. The first relief sections extend between a piston head and respective piston bosses whist the second relief sections extend downward from the respective piston bosses. The narrowed relief sections are spaced from each other in parallel to piston pin holes at a distance which is smaller than that at which the first and second relief sections are space from each other, respectively. The narrowed relief sections are formed thicker and therefore more rigid than the first and second relief sections so that the piston skirt is more rigid adjacent the piston bosses and less rigid above and below the piston bosses, whereby to effectively lessen side thrust of the piston to the cylinder wall without deteriorating the durability.

Abstract: In order to ensure an adequate supply of oil onto the thrust surfaces of a reciprocating type internal combustion engine piston, recesses are formed in the skirt proximate each thrust surface. The boundary defined between the surface of the skirt and the recess is defined by a rounded surface which smoothly merges the recess with the surface of the skirt, eliminates sharp edges, and permits oil to flow uninhibited out of the recess onto the thrust surfaces.

Abstract: A method of supplying scents to a room of a motor-car. In this method, a scent holder is provided within the room of the motor vehicle, the scent holder containing scents bearing materials for emitting different scents useful for a driver of the motor vehicle. Reference data for respective driving conditions of the motor vehicle are stored, the reference data indicating need for supply of respective scents. After storing the reference data, a driving condition of the motor vehicle is detected for producing an electric drive signal representing the driving condition. The drive signal thus produced is compared with a corresponding reference datum for determining whether or not the detected driving condition requires one of the scents contained in the scent holder. When the detected driving condition requires the one scent, one scent bearing material containing the one scent is selected. Then, the one scent from the one scent bearing material is supplied to the room of the motor vehicle.

Abstract: The present invention relates to a fragrant air supplying method, supplying apparatus, and a building having a fragrant air supplying system for supplying fragrant air to the rooms. A fragrant-material supplying means supplies fragrant material to a mist-generating means to generate mist either by blowing air or by vibration produced by an ultrasonic-oscillating means. The mist is blown to a surface portion formed at the end of a fragrant-air separating means which separates evaporated fragrant air from mist. The fragrant air is then introduced into holes formed in a fragrant-air discharging means, in which the place of holes are offset from the surface portion toward the downstream of the fragrant air. The fragrant air is then blown into a distributing passage from the fragrant-air discharging means to mix the fragrant air with conditioned-air supplied by an air-supplying means.
