Title: Detection of front and rear surfaces of recording sheet
Inventor: SUZUKI AKIO
IPC: B41J29/00
Filed: 1988-04-18
Abstract: PURPOSE:To prevent improper insertion of a recording sheet by automatically detecting a front and a rear surfaces of the recording sheet by a method wherein a quantity of reflected light from the front surface and the rear surface of the recording sheet is detected, and the front or rear surface is discriminated based on a difference in the quantity of reflected light from the front and rear surfaces. CONSTITUTION:Sensors 66, 67 detecting states of a front surface and a rear surface of a recording sheet are arranged at required positions on a path of the recording sheet 45, and detection signals 66A, 67A from the sensors are transmitted to a control circuit 53. In the case of a coarse surface of paper or the like, light of intensive directivity irradiated through a slit 73 from a light source 71 is scattered on a surface of the recording sheet 45, and a quantity of reflected light incident upon a light receiving element 72 arranged on the path of the reflected light decreases to a low level of a fraction of irradiation light. In the case of a smooth surface such as a surface of a BPF or the like, the quantity of the reflected light does not decrease less than that of the irradiation light, and is kept at a high level. Thus, a class of, or the front or rear surface of the recording sheet 45 can be detected based on a difference in the quantity of the reflected light between the front surface and the rear surface of the recording sheet.

Filed: 1986-04-25
Abstract: PURPOSE:To improve the water absorbing faculty and the stability of the friction coefficient for the change of the environment such as adhesion of water, etc. by allowing the frictional member which is formed by jointing carbon fibers by carbon to have a number of gas holes due to the partial defect of the carbon fiber. CONSTITUTION:An ordinary C/C composite is a carbon-fiber-reinforced composite material which is formed by jointing carbon fibers by carbon, and has the orthogonal structure of the bundles of carbon fiber 2. Since, in the C/C composite, the arrangement of the carbon fiber is fine, and the porosity is small, the water absorbing faculty is inferior. Therefore, the carbon fiber 2 is compounded with a proper quantity of low heat resisting fibers 3, and a bundle is obtained, and an orthogonal structure is prepared by laminating said bundles. Then, the frictional member 1 is impregnated with resin, and heated to carbonize the resin. Further, the material 1 is impregnated with resin again and heated, and then the low heat resisting carbon 3 is combusted, and cavities are formed, and the porosity is increased to improve the water absorbing faculty.

Abstract: PURPOSE:To improve both operability and reliability for a back-up device of a control system by informing previously the set information to an upstream system from a manual operation device and controlling the control output signal with a manual operation device only when an increment or decrement button. CONSTITUTION:When a CPU within an upstream system 1 detects an HAND state, the control output ei is controlled so that the output ei is equal to the feedback signal ef to be given to the system 1. The contact of an automatic changeover switch SW is connected to the (a) side when an increment/decrement button 22 is not pushed. Then the control signal can be operated by varying the output ei. When the button 22 is pushed, the contact of the switch SW is changed to the (b) side. Thus the control signal obtained by a manual operation is delivered from an analog memory 31 and changes bumplessly. When the button 22 is released, the output is kept at the level em of a manual controller 2 obtained immediately before the button 22 is released. Thus the control output eo has no change.
