Rotary piston engine includes a substantially triangular rotor formed with flank cooling oil passages located behind flanks of the rotor. The rotor further has coolant oil passages behind the oil seals at the opposite side surfaces thereof. The flank cooling oil passages are supplied with cooling oil only when the rotor temperature or engine speed is beyond a predetermined value, while the oil seal cooling passages are always supplied with cooling oil so that the rotor flanks can be maintained at a high temperature while preventing the oil seals from being excessively heated.

An image processing device, which includes: an original reception unit that receives an original image; a dot image generation unit that generates, on the basis of additive information to be added to the original image, a dot image in which a plurality of dots each formed by one or more pixels are arranged; a state alteration unit that, when any of the dots in the dot image is determined to be not extractable, alters a state of the non-extractable dot on the basis of a relationship between a position on the dot image generated by the dot image generation unit and a corresponding position on the original image; and a composite image generation unit that generates a composite image by superimposing, on the original image, the dot image having the state of the non-extractable dot altered by the state alteration unit.

An apparatus of feeding mailpieces such as envelopes is disclosed. The apparatus includes a supply conveyer for supporting thereon an array of mailpieces which are arranged in a tilted-backward position and moving such mailpieces forward, and a suction feeder which is located downstream of the supply conveyer for picking up by suction a forefront mailpiece from the array of mailpieces on the supply conveyer. The suction feeder has a rotary drum, a shaft rotatably supported in the drum and disposed with the axis thereof oriented in parallel to and offset from the axis of the drum. An external gear is fixed on the shaft for rotation therewith and a stationary internal gear engages with the external gear, the gear ratio of the external gear to the internal gear being n:n+1, wherein n represents an integer. A plurality of suction means arranged at positions radially spaced at a predetermined distance from the shaft and substantially equiangularly spaced from each other and movable integrally with the shaft in conjunction with the rotation of the drum for picking up each forefront mailpiece from the array of mailpieces on the supply conveyer.

In a SOHC type internal combustion engine having a single camshaft, a fuel injector is provided for directly injecting a fuel into a combustion chamber, and an intake port is provided such that one end of the intake port is open at intake openings to the combustion chamber. The intake port extends toward the top face of a cylinder head between the camshaft and two intake valves, such that at least a part of the intake port passes through a region between the shortest lines connecting respective head portions of the intake valves and the camshaft.

In a method for manufacturing a BiCMOS semiconductor device including bipolar transistors and MOS transistors, a thin gate oxide film is formed on a principal surface of a semiconductor substrate, and a first polysilicon film is formed on the thin gate oxide film. This first polysilicon film is selectively removed from a bipolar transistor formation area, and impurities are introduced into a principal surface region of a semiconductor substrate through only the thin gate oxide film so that a collector region is formed in the semiconductor substrate in the bipolar transistor formation area, and a base region is formed in the collector region, Therefore, a second polysilicon film is formed on the whole surface, and the second polysilicon film and the underlying thin gate oxide film are removed from an emitter formation area within the base region. A third polysilicon film having a high impurity concentration is formed on the whole surface, and thereafter, the polysilicon layers are patterned to form a gate composed of the first, second and third polysilicon films, and an emitter composed of the second and third polysilicon films. The impurity included in the third polysilicon is thermally diffused in the base region so that an emitter region is formed in the base region. Thus, without increasing the number of masks, and without giving an adverse influence to the MOS transistor, the performance of the bipolar transistor can be elevated, and the stable yield of production can be realized. In addition, the microminiaturization of the bipolar transistor becomes possible

An oxidizable metal film and a barrier metal film are formed in the named order on an insulating film formed on a semiconductor substrate or in a contact hole formed through the insulating film. A gold film is selectively formed on the barrier metal film in alignment with the contact hole. The barrier metal is selectively removed using the gold film as a mask, and an exposed surface of the oxidizable metal film is oxidized. A second metal film is deposited on only a surface of the gold film by an electroplating using the oxidized surface of the oxidizable metal film as an anti-plating mask. Finally, the oxidizable metal film not covered by the gold film is completely oxidized.
