Abstract: A type printer in which deterioration of a platen is prevented by distributing positions of impacts on the platen by a printing head over the whole region of peripheral surface of a cylindrical platen. The drive shafts of a paper feed roller, platen, and tractor are operatively connected to each other by a gear train, and driven by a motor. The gear ratio of gears in the gear train is selected so that the peripheral velocities of the paper feed roller, platen, and tractor agree with each other. The platen rotates in synchronism with the feed velocity of paper fed by the paper feed roller and the tractor, by which the positions of impacts, which are effected by the printing head, are distributed over the whole region on the peripheral surface of the platen.

Abstract: First and second sheet guides (21, 31) are arranged individually in front and at the back of a print head (6) in a sheet feeding direction. Each of these sheet guides (21, 31) has an arcuate end edge opposite to the print head (6), the width-direction central portion of the end edge being located at the longest distance from the print head so that the space between the end edge and the print head gradually increases with lateral distance from the width-direction central portion of the end edge. In consequence, the leading end portion of a sheet that is printed by means of the print head (6), especially its opposite ends, can be prevented from abutting against the sheet guides (21, 31) and causing jamming due to deformation of the sheet or the like as the leading end portion of the sheet passes through a gap between a conveyor plate (9) and the sheet guides (21, 31).

Abstract: A mulching mower is provided which is capable of cutting grasses finely without leaving uncut grasses and which is capable of discharging the cut grass clippings onto the cut grass path so as to be evenly dispersed. A pair of cutter blades are arranged to the right and to the left of the mulching mower in a cutter housing which opens downwardly. A guitar-shaped or figure 8 shaped enclosure wall hangs down from an under surface of an upper wall of the cutter housing to completely surround the periphery of the right and left cutter blades along tip end rotation loci of the blades at a slight distance therefrom. The enclosure wall is formed by side wall portions ar right and left outsides of the cutter housing and front and rear enclosure wall portions hang down from the under surface. The cutter blades rotate in opposite directions from each other so that tip ends of the cutter blades move from front to rear at right and left outsides, respectively, of the mulching mower.

Abstract: In a utility vehicle, a muffler accommodating chamber is defined in front of and below an engine mounted at a front portion of a vehicle frame. A rear wall of the muffler accommodating chamber is formed by a front axle frame which is mounted to extend between both of vertical frame portions of the vehicle frame and supports a front axle beam for rotatably supporting front wheels at its opposite ends. The front axle frame has a function to support the front axle beam, a function as a strength member in the form of a cross member, and a function as a member defining the muffler accommodating chamber. A driving gear is mounted to a steering shaft and thrust-supported by a lower surface of a support portion of a support frame which is fixedly mounted on the vehicle frame. A driven gear meshed with the driving gear and a pitman arm are connected to a rotary shaft whose axially upward movement is limited by the support portion and whose axially downward movement is limited by a bracket mounted to the vehicle frame.

Abstract: A working fluid circuit for an active suspension control system for an automotive vehicle comprises a pressure source unit which provides pressurized working fluid to actuators, associated with wheels respectively, which are operable to suppress attitude change of a vehicle body, pressure control valves associated with the actuators respectively, and check valves located in a by-pass from an output port to a supply port of the pressure control valve, the supply port communicating with the pressure source through a supply line to which the working fluid is supplied from the pressure source, the output port communicating with the actuator through an output line for outputting the working fluid adjusted at a preselected controlled level to the actuator.

Abstract: An apparatus for heat-treating pipes comprising a furnace chamber for accommodating a plurality of pipes as arranged in parallel, a chain conveyor disposed in the furnace chamber for transporting the pipes in a direction at right angles to the axes of the pipes, and a plurality of stopper means for stopping the pipes intermittently at suitably spaced-apart positions in the path of transport by the chain conveyor and causing each of the pipes to rotate about its own axis in cooperation with the chain conveyor. Since the pipe is intermittently stopped and rotated about its own axis during heat treatment, the pipe is free of thermal deformation to an elliptical shape. Pipes can be heat-treated in succession in a small space, therefore with a very high efficiency. The motion of the chain conveyor is utilized for rotating the pipe without necessitating any additional device for the rotation.

Abstract: An apparatus for cleaning a photosensitive member of an electrostatic copying machine which includes neutralizing means electrically connected to the ground and disposed for contact with the surface of a photosensitive member in a region located between a transfer station where a toner image formed on photosensitive member is transferred onto a transfer sheet and a cleaning station where any residual toner remaining on the photosensitive member after the transfer step is removed. In this manner, the photosensitive member is neutralized after the transfer step before the residual toner is removed therefrom.

Abstract: An image transfer unit provided with cleaning means for use in an electrophotographic copying machine comprising an electrically conductive transfer roller disposed in abutting relationship with a photosensitive member, an electrically conductive, rotatable cleaning means disposed in abutting relationship with the transfer roller, and electrical bias means connected with the cleaning means and having a switchable polarity. During a transfer step, a bias voltage of opposite polarity to that of the toner is applied to the transfer roller through the cleaning means. At this time, toner attaching to the transfer roller is electrostatically transferred onto the cleaning means. During a cleaning step, a bias voltage of the same polarity as the toner is applied to the cleaning means, whereby the toner attaching thereto is transferred back to the photosensitive member through the transfer roller. The toner which is transferred back to the photosensitive member is removed by separate cleaning means.
