An apparatus and method for excavating tunnels with a shield and slurry while detecting and preventing excess excavation in high water content soft ground wherein, in each of feeding system of slurry to tunnel face and discharging system of a mixture of slurry and excavated soil or the like as well as gushing water from the tunnel face out of working area, the respective volumes of the slurry and mixture passing through the respective systems are measured in positions close to the tunnel face, the volume of the excavated soil or the like is determined with the difference between both volumes while the amount of propelling a tunnelling machine is determined as an excavated space volume of the tunnel, the respective values of the excavated soil volume and excavated space volume are compared with each other, whereby the amount of propelling the machine, fed amount of the slurry or discharging amount of the mixture can be properly adjusted so that the difference between said values will be made substantially zero.

A reciprocating driving device is provided with a reciprocating moving member supported to be movable in a predetermined direction and the reverse direction. A first rack is provided on the reciprocating moving member, and a second rack is provided on the reciprocating moving member and arranged so as to face the first rack. A gear moves the reciprocating moving member in the predetermined direction or the reverse direction by rotating in a predetermined direction, selectively meshing with the first rack or the second rack.
摘要:
It is an object of the present invention to provide a simulation tool, which can overcome complications of examinations by simulations as described above and can provide a designer with easy examinations. A simulation based on a design parameter of a unit is implemented. Furthermore, a simulation result implemented by the control device is output on a display screen as a graph. Then, the unit design parameter is corrected in accordance with a correction in the graph displayed on the display screen. Thus, the simulation can be retried easily.

The invention provides an aided design apparatus including a output element for outputting data of an attribute name associated with an attribute group of a part used for transporting a sheet along with three-dimensional shape data of the part. The invention further provides a related aided design method and a recording medium for recording a program for carrying out the method, wherein the data of parts used in a simulation for paper transportation can be easily exchanged.
摘要:
The image forming apparatus has exposing device, conveying device, and sheet detecting device for detecting the sheet conveyed by the conveying device, which is disposed between the transferring portion and the conveying device, and control device for judging whether or not it is possible to start exposure by the exposing device before the leading edge of the sheet conveyed by the conveying device reaches the sheet detecting device after the leading edge of the sheet passes through the conveying device and for controlling so that causing the sheet conveyed by the conveying device is stopped in front of the sheet detecting device until it is determined that it is possible to start exposure by the exposing device. In the image forming apparatus, the image forming apparatus starts to form a latent image by the exposing device based on the detection of the sheet by the sheet detecting device.
摘要:
An image fixing apparatus includes a heater; an endless film movable together with a supporting member for supporting a toner image, in which the toner image is heated by heat from the heater through the film; a driver for driving the film; and a limiter for limiting the lateral position of the film. At least a part of the endless film is limited by the limiter and is substantially tension-free when the film is driven.
摘要:
A process cartridge detachably mountable to an image forming apparatus includes a device contributable for forming an image; a developer accommodator; and a sealing member between the image forming device and the developer accommodator, wherein the sealing member is provided by injecting a liquid material which becomes an elastomer when it is solidified.
摘要:
An image forming apparatus comprising an image forming unit for forming a non-fixed toner image on a recording material, a heater for heating the non-fixed toner image, a back-up member for cooperating with the heater to form a nip therebetween, the back-up member pinching and conveying the recording material at the nip in such a manner that the non-fixed toner image is contacted with the heater so that the non-fixed toner image is fixed to the recording material by heat from the heater, and a cleaning member for cleaning the back-up member. The cleaning member is brought into a first and second cleaning mode in which an image forming operation is not effected and the back-up member is cleaned, the second cleaning mode having a cleaning time longer than a cleaning time of the first cleaning mode.
