Abstract: An electromagnetic clutch reduces clutch operating noise at a low cost by utilizing elastic members which are suited to a spring force of a leaf spring. An approximate nonagonal leaf spring has an outer ring portion, attachment portions connected to a hub, and connecting portions. Under the outer ring portion, securing portions of an armature are disposed. First elastic members are disposed at intermediate points of the securing portions, and a second elastic member is disposed in a gap between the leaf spring and the hub along an axial direction. When actuating the electromagnetic clutch, the leaf spring compresses the second elastic member, and when stopping the electromagnetic clutch, the armature collides with the first elastic member so that an axial position of the armature is secured.

Abstract: In the disclosed electromagnetic clutch, a bent porion (15a) of a plate (15) comes into contact with an armature (6) attempting to move beyond a predetermined movable range, thereby restricting the movement of the armature (6). As a result, if an elastic member (14) is fused, a trouble is prevented which otherwise might be caused by the movement of the now-unsupported armature (6) beyond a predetermined movable range.

Abstract: The technique is provided that reduces degraded quality in printed results due to nozzles employed to record dots on each pixel in combination with the order in which these dots are recorded on pixels. A plurality of nozzles on a print head are grouped, in order from the nozzles that first reach a point over the print medium, into a first nozzle group, a second nozzle group, and a third nozzle group. During main scanning, certain pixels in main scan lines positioned facing the nozzles of the first nozzle group are targeted for dot recording. All pixels contained in main scan lines positioned facing the nozzles of the second nozzle group are targeted for dot recording. Those pixels among the pixels contained in main scan lines positioned facing the nozzles of the third nozzle group, and that have not previously had dots recorded thereon by the first nozzle group in a previous main scan, are targeted for dot recording.

Abstract: While performing main scanning in which a head having a plurality of nozzles that eject ink is moved in prescribed forward and reverse main scanning directions relative to a print medium, print images are printed on the print medium by forming dots in each pixel aligned in the main scanning direction in accordance with print data. The dot formation position misalignment amount for each nozzle is corrected using image pixel value data indicating the existence of image pixels comprising images and adjustment pixel value data indicating the existence of adjustment pixels in which dots are not formed.

Abstract: A carburetor fuel mixture adjustment assembly has a threadable holder which suppresses rotation of a needle valve body disposed within an elongated receptacle defined within a carburetor body. The threadable holder is rigidly engaged within a threading chamber of the receptacle. During assembly, the needle valve body is extended through a bore of the holder as a threading portion of the valve body rotateable cuts an interior threading groove into the threadable holder. The threadable holder is held rigidly within the threading chamber by the carburetor body. A sealing holder is disposed within the receptacle axially inward of the threadable holder and is prevented from rotating within the receptacle by the threadable holder. A stem holder portion of the sealing holder assures a needle portion of the needle valve assembly remains concentrically disposed within an outlet orifice of a fuel chamber of the receptacle.

Abstract: In an n-th primary scanning (forward trip) the rasters by white circle dots are formed. After this primary scanning, printing paper is conveyed toward a secondary-scanning-direction downstream side by the secondary scanning distance which is the same as the interval d between dots, and in the (n+1)-th primary scanning (backward trip) after the conveyance, the rasters by black circle dots are formed. Subsequently, the printing paper is conveyed toward the secondary-scanning-direction downstream side by a secondary scanning distance of (2N−1)·d, and in the (n+2)-th primary scanning (forward trip) after the conveyance and the (n+3)-th primary scanning (forward trip) after the conveyance by a secondary scanning distance d, white circle and black circle dots are formed, respectively. Thus, an image is printed in units of two adjacent rasters formed by the same nozzles.

Abstract: Before transmitting print data, a print controller transmits to a printer information on a thickness of a printing medium corresponding to a sort of printing medium which is selected on a select screen by an operator in a state that the medium thickness information is contained in control data for the print data. In the printer, a timing correction section corrects a timing of ejecting an ink drop onto a printing medium in the forward and reverse scans executed by the recording head in accordance with the control data containing the medium thickness information. Accordingly, stress imposed on the operator when the printer prints on various types of printing media in a bi-directional printing mode can be reduced.

Abstract: A torque limiting mechanism includes an axial space formed in a cylindrical wall of a pulley, and a pin protruding and extending from a back surface of a discharge disc. The pin is inserted into the axial space, and a rubber damper is installed between the inner surface of the axial space and the pin. When torque difference between the pulley and the discharge disc exceeds a threshold, a root portion of the pin is broken to separate the discharge disc from the pulley, thereby interrupting rotation transmission from the pulley to the discharge disc.

Abstract: In order to reduce an electromagnetic clutch in an axial size, a ring-shaped leaf spring connects an armature to a hub. The leaf spring has an outer ring portion connected to the armature, an attachment portion connected to the hub and located inner than the outer ring portion, and a connecting portion for connecting the outer ring portion and the attachment portion. A plurality of rivets of the armature are disposed at the outer ring portion. An embossed portion for generating an initial deflection on the leaf spring is disposed at an intermediate portion between the rivets in the circumferential direction of the outer ring portion.

Abstract: A spring plate member is connected to a hub. The spring plate member includes a plate spring portion generating a resilient force to separate an armature from a rotor, and an outer ring portion, which faces the armature. An elastic member is provided between the armature and the outer ring portion for connecting the armature directly with the outer ring portion. Thus, operation noises of the electromagnetic clutch and a compressor are efficiently reduced. Further, the axial dimension of elastic member can be made much smaller than that of the conventional cylindrical elastic member.

Abstract: An electromagnetic clutch has an armature, a rotor housing accommodating a stator housing and an exciting coil having negative and positive terminals. A passage is formed to extend from an outer peripheral surface of the stator housing to the negative terminal and the positive terminal. The passage is filled with a conductive metal member having a melting point lower than that of the stator housing between the outer surface of the stator housing and the negative terminal. When frictional heat generated between the armature and the rotor housing exceeds a preset value, the metal member melts and flows to the positive terminal, thereby short-circuiting the coil. As a result, a fuse between a power source and the clutch is fused, thereby turning off the clutch. Therefore, the clutch does not need to have a thermal fuse therein and is reduced in size without increasing power consumption.

Abstract: A host computer converts an entered gray scale image into a raster image expressing multiple tonal ranges, using an intermediate spot pattern determined in advance. Here, the intermediate spot pattern is a spot pattern composed of pixels which can take only binary value densities with information indicating tonal ranges embedded in the manner of arrangement of the pixels in the spot pattern. Therefore, this raster image logically expresses a large number of tonal ranges which cannot be actually expressed with pixels in binary value densities. A printer receives this raster image from the host computer and converts the intermediate spot pattern in this raster image into an output spot pattern which can assume tertiary values or more in density, thereby printing out a half-tone image actually expressing multiple tonal ranges.
