A pressing wall is provided in a part of the entire area of the first carrying chamber in which a first screw member is housed. The area is opposed to a bottom wall of the first carrying chamber on the lower side in the gravity direction of the first screw member and opposed to the side walls of the first carrying chamber on both lateral sides orthogonal to a rotation axis direction of the first screw member. In the area, a toner concentration of a K developer being carried is detected by a K toner concentration sensor. The pressing wall comes into contact with, from above in the gravity direction, the K developer, which moves from a lower side to an upper side in the gravity direction according to the rotation of the first screw member, and presses the K developer downward in the gravity direction.

A speed change detection apparatus includes an image carrier for carrying a latent image, and a latent image pattern forming device for forming a latent pattern image on the image carrier. The pattern image includes periodically formed line or dot images. An alternating current conversion type surface potential sensor is provided to detect a potential of the surface of the photoconductive member. The alternating current conversion type surface potential sensor further detects a change in speed of the image carrier by detecting a moiré appearing on the latent image pattern.

An image recording system includes two image recording apparatuses each capable of recording images independently. A color image recording apparatus is disposed with a bypass transporting path apparatus. A transporting path connecting apparatus is disposed between the front of a monochrome image recording apparatus and the back of the color image recording apparatus. A final processing apparatus that is common to the color and monochrome image recording apparatuses is disposed in the front of the color image recording apparatus. This system includes a process switching portion that switches an image recording process executed by one image recording apparatus to a substitute image recording process of the other image recording apparatus and a switching determining portion that determines whether the switching is executed by the process switching portion, depending on whether a predetermined condition is satisfied.

An ion-generating component has, on an insulating substrate, a ground electrode, a high-voltage electrode, an insulating film provided on the surface of the ground electrode, and a wire electrode. A cutout is formed by cutting out one side of the insulating substrate. The root of the wire electrode is soldered to the high-voltage electrode, and the leading end thereof is positioned near the cutout. The wire electrode is made of an ultrafine wire having a diameter of about 100 μm or less, for example, a piano wire, a tungsten wire, a stainless wire, or a titanium wire.

A shift control apparatus of an automatic transmission of a motor vehicle to which torque is transmitted from an engine via a fluid coupling device is provided. In the automatic transmission including a plurality of hydraulically operated friction elements, a clutch-to-clutch downshift is carried out during coasting of the vehicle by releasing one of the friction elements and engaging another friction element. A controller of the shift control apparatus detects a difference between input and output rotation speeds of the fluid coupling device, and increases an engine speed by a controlled amount based on the difference between the input and output rotation speeds when the clutch-to-clutch downshift is carried out during coasting of the vehicle, so that the vehicle is brought into a minimal driving state in which the engine speed is slightly higher than the output rotation speed of the fluid coupling device.

An image recording material, includes: a support; and an image recording layer disposed on the support, and having a depression-and-protrusion at least on a part of an image face of the image recording material after an image recording. The depression-and-protrusion defines a slope inclined from the image face. The depression-and-protrusion of the image face has a ten point height of roughness profile Rz in a range from 5 μm to 25 μm and has an average depression-and-protrusion space Sm defined in JIS B0601-1994 in a range from 100 μm to 1000 μm.
摘要:
The present invention relates to a cooling fan failure detection apparatus for a hybrid vehicle. This apparatus comprises a cooling capacity calculation device which calculates a cooling capacity of a cooling fan provided in the hybrid vehicle; a battery heating value calculation device which calculates a heating value of a battery provided in the hybrid vehicle; an assumed temperature change calculating device which calculates an assumed temperature change of the battery based on the heating value and the cooling capacity; an actual temperature change calculating device which calculates an actual temperature change of the battery; and a failure determination device which determines whether the cooling fan is failing by comparing the assumed temperature change calculated by the assumed temperature change calculating device and the actual temperature change calculated by the actual temperature change calculating device.
摘要:
An image forming apparatus includes an apparatus body and a rotary developing unit or revolver. The apparatus body includes a connection unit having a single optical transmission/receipt section. The revolver includes a connection unit having four optical transmission/receipt sections arranged at the intervals of 90 degrees in the circumferential direction of the revolver. All the transmission/receipt sections are spaced from the axis of the revolver by the same distance. When the revolver is brought to a stop at a preselected developing position, one of the four transmission/receipt sections of the revolver faces the transmission/receipt section of the apparatus body without fail. The connection units include a current transformer for feeding power from the apparatus body to the developing unit. The connection units face each other at parallel surfaces thereof.
摘要:
A support for a photographic printing paper comprising a substrate having a back side on which side an emulsion layer is not coated and a front side, and both sides of the substrate are coated with a waterproof resin coating. The waterproof resin coating on the back side of the substrate is a multi-layer laminate comprising an upper resin layer and a lower resin layer provided nearer to the substrate than the upper layer. The lower resin layer contains high density polyethylene having an MFR of not less than 8 in an amount of not less than 90% by weight based on the total weight of resin. Furthermore, the lower resin layer is thinner than the upper layer.
摘要:
An image forming device includes a plurality of developing devices and a photosensitive drum. Each of the developing devices includes a developer carrying roller. One of the developing devices is moved to a developing position confronting the photosensitive drum which is formed with a latent image. A first developing bias including a d.c. component and an a.c. component is applied to the developer carrying roller and developer on the developer carrying roller is rendered in contact with the latent image on the photosensitive drum so that the latent image is developed. On the other hand, when the developer on the developer carrying roller comes in contact with and separates from the photosensitive drum due to the movement of the developing device, a second developing bias is applied to the developer carrying roller. The second developing bias generates an electric field where the developer on the developer carrying roller is more reluctant to move toward the photosensitive drum as compared with the first developing bias. The second developing bias may include only a d.c. component.
