摘要:
An object of the present invention is to provide a multi-cylinder rotary compressor which can enhance the reliability by improving the compression efficiency/mechanical efficiency. The bearings are fixed on the inner wall of the closed container, the cylinders are fixed to the bearings, and a gap is formed between the respective cylinders and the inner wall of the closed container. The design with the relatively large internal volume of the closed container is possible, and the reliability can be enhanced. Further, improvement in the compression efficiency and the mechanical efficiency can be achieved with the compact multi-cylinder rotary compression element.

A pressure receiving surface (8) having a diameter gradually decreasing in an axially inward direction is formed at an outer end portion of a pin (1), whereas a pressing portion (7) is formed at a circumferential edge of an opening of a pin insertion hole (5) of a link (2). A retaining ring (3) is formed with a friction surface (9) to be press-contacted to the pressure receiving surface (8) when a force is applied from the pressing portion (7) upon development of a relative movement in a disengaging direction. The retaining ring (3) and the pressure receiving surface (8) share a greater area of contact than in the prior art, providing sufficient friction. This makes possible to provide a fastening structure of the link and the pin of a crawler belt which can be assembled by simple operation at a low cost, without requiring a high machining accuracy, and thus can be manufactured at a low cost.

An automatically operated shovel, which includes a power shovel and an automatic operation controller 50 for making the power shovel reproduce a series of taught operations ranging from digging to dumping, is characterized in that the automatic operation controller is provided with a positioning determination means 511 for determining whether or not the power shovel has reached within a taught position range predetermined based on corresponding one of positioning accuracies set for individual taught positions of said power shovel, and, when the power shovel is determined to have reached within the predetermined taught position range, the automatic operation controller outputs a next taught position as a target position.

A toner is formed of toner particles each comprising a binder resin and iron oxide particles dispersed therein. The toner particles are characterized by uniform but non-surface-exposed dispersion of the iron oxide particles within the toner particles as represented by (i) a carbon content (A) and an iron content (B) giving a ratio B/A

摘要:
There are provided a tape cartridge-holding mechanism which is capable of reliably and immovably holding a tape cartridge in a cartridge compartment without spoiling the ease of mounting and removal of the tape cartridge, and a tape printing apparatus including the tape cartridge-holding mechanism. The tape cartridge-holding mechanism comprises a lid for opening/closing a cartridge compartment, at least one pair of left and right holding nails for engaging with a tape cartridge mounted in the cartridge compartment and thereby sandwiching the tape cartridge such that the holding nails press the tape cartridge against a bottom surface of the cartridge compartment, and an urging mechanism arranged in contact with at least one of the pair of holding nails, for urging the holding nail in a direction of sandwiching the tape cartridge as closing operation of the lid is carried out.
摘要:
A toner suitable for use in electrophotography, etc., is composed of toner particles each containing a binder resin, a colorant and a wax component. Each toner particle has such a microtexture as to provide a cross section as observed through a transmission electron microscope (TEM) exhibiting a matrix of the binder resin, a particle of the wax enclosed with the matrix; and the binder resin dispersed in a particulate form in the wax particle, and the toner particles have a residual monomer content of at most 500 ppm by weight of the toner particles. The colorant may also be dispersed in the wax particle enclosed within the matrix of the binder resin.

There is provided a rotary type regenerative heat exchanger which can effectively prevent an air bypass leak or a gas bypass leak. A rotary type regenerative heat exchanger of the present invention has a rotor (4) rotating around a central shaft (2), a heat accumulator (8) which is constructed in a manner that an air (A) of being a heated fluid and a gas (G) of being a heating fluid filled in the rotor alternately pass therethrough by a rotation of the rotor to repeat heat accumulation and radiation, and a housing provided so as to house the rotor. Further, the rotary type regenerative heat exchanger comprises: a branch pipe (41, 47, 55) for taking out a part of the heating fluid; a seal gas fan (42, 48, 56) for pressurizing the taken-out heating fluid to a predetermined pressure; and a seal gas introducing duct (46, 52) which is provided in the housing so as to introduce the pressurized heating fluid into a predetermined space formed between the rotor and the housing.
摘要:
A method and device for diagnosing a vehicle, in which a forced activation signal Sx is supplied to a diagnostic target part through an ECU. A current state of the detected diagnostic target part is compared with a state predicted when the forced activation signal Sx is given to diagnose the diagnostic target part. The forced activation signal Sx when the diagnostic target part is judged to be good, or after a predetermined time has elapsed since issue of the signal Sx was initiated.
摘要:
In a travelling crawler belt in which a pair of left and right links are connected by pins respectively press-fitted into the corresponding links, a fixing end surface of the pin or the links is continuously and locally pressed and deformed in an axial direction of the pin from the fixing end surface, along an inner or outer peripheral portion of an opening of a pin-press-fit hole. Then, a part of the opening peripheral portion of the end of the pin or the link is enlarged or reduced in diameter, so that the diametrically increased or reduced portion is retained and fixed to a mating retaining space. With this fixing method, it is possible to easily and strongly couple the links and the pin, and to obtain a fixing structure of the links and the pin for a crawler belt capable of sufficiently securing a holding force of the pin in the axial direction. When the pin is fixed at the time of the assembling of the pin, an existing press can be used without requiring any exclusive machine, and it is possible to easily and reliably assemble the links and the pin for the crawler belt.
