Abstract: PURPOSE:To eliminate the difference in fixing property in the lateral direction of a sheet between one-sheet printing and consecutive printing by individually controlling heaters provided on a paper-feeding area and non paper-feeding areas, and making a surface temperature distribution almost constant over the full length of a fixing roller. CONSTITUTION:In the fixing roller 1, a heater for the paper-feeding area 2A is provided on the central part of the central shaft of a cylindrical body, and a heater for the non-paper feeding areas 2B on the both edge parts apart from the central part: The heaters are connected to a temperature control circuit 6 through heater terminals 3A and 3B, respectively. A thermistor 4A for the paper-feeding part and a thermistor 4B for the non paper-feeding area which detect the surface temperature of the fixing roller 1 are slightly brought into contact with the surface of the fixing roller 1, and their detection outputs are inputted into the temperature control circuit 6. Then, the heaters 2A and 2B are individually controlled by the temperature control circuit 6 based on the detection outputs of the transmitter 4A and 4B, respectively, so that the surface temperature distribution is made almost constant over the full length of the fixing roller 1. Thus, the difference in the fixing property in the lateral direction of the sheet between the one-sheet printing and the consecutive printing is eliminated, and thereby attaining the constant fixing property.

IPC: H04N19/52
Filed: 1994-04-20
Abstract: PURPOSE:To provide the video encoder which can reduce circuit scale in comparison with the case of using a full searching method and can be provided with picture quality close to the full search method. CONSTITUTION:A search information calculator 102 calculates one candidate vector from motion vector values stored in a motion vector memory 101. A high-accuracy computing element 103 sets a second search area which includes a block to be predicted by the candidate vector and is smaller than a search area on a reference frame, sets a candidate vector with accuracy smaller than one picture element and calculates a predictive error value for each candidate vector. A low-accuracy computing element 104 sets a candidate vector with accuracy larger than two picture elements inside the first search area on the reference frame and calculates a predictive error value for each candidate vector. A predictive error comparator 105 compares the predictive error values calculated by the high-accuracy and low-accuracy computing elements 103 and 104 so that the motion vector value of the encoded block can be decided.

Title: Slip angular velocity correcting device
Inventor: YAMAGUCHI HIROYUKI
IPC: B60T8/1761
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To correct the error of a sensor which detects the moving state of a vehicle caused by an offset when the offset occurs in the sensor. SOLUTION: The slip angular velocity β(.)+Δβ(.) of a vehicle is calculated from the lateral acceleration y(..), yaw rate θ(.), and car speed V of the vehicle (100). On the other hand, the estimated value βh of the slip angle of the vehicle is found from the steering angle δf, car speed V, and a prestored vehicle model (102) and the estimated value βh (.) of the slip angular velocity is calculated by differentiating the estimated value βh (106). Then an offset error Δβ(.) is obtained by eliminating a modeling error by removing s high-frequency component from the deviation Δβg (.) between the calculated and estimated values of the slip angular velocity (108).  Finally, a slip angular velocity containing no offset error is obtained by subtracting the offset error Δβ(.) from the slip angular velocity β(.)+Δβ(.) (110).

Abstract: PROBLEM TO BE SOLVED: To provide an incoherent light source high in luminance by exciting a phosphor with semiconductor laser beam guided through a fiber-type light wave guide path and taking out luminescence by the phosphor to outside of the fiber-type light wave guide path. SOLUTION: Light emitted from a semiconductor laser 10 is collected onto an end surface of an optical fiber through a lens 11 and guided to a core portion 13. Reflection films 15, 16 are formed on the end surface of the optical fiber 12. Phosphor 17 is added to a clad 14 of the optical fiber 12. Because a part of semiconductor laser light (wavelength λ1) guided into the optical fiber 12 penetrates into the clad 14, the phosphor 17 emits light (luminescent center wavelength λ2) using the laser light as exciting light. This light is taken out of an outgoing end surface of the optical fiber 12. At this time, the oscillation wavelength λ1 of the semiconductor laser 10 as the exciting light and the luminescent wavelength λ2 of the phosphor must satisfy the relation λ1< λ2.

Title: Preparation of asphalt board
Inventor: KUMASAKA SADAO
IPC: B29K95/00
Filed: 1984-04-25
Abstract: PURPOSE:To obtain a porous board excellent in acoustic absorptivity by dividing an asphalt foam into fine pieces, spreading them nearly flatly, compressing and heating them. CONSTITUTION:Pieces of the asphalt foam spread to the specified thickness, compressed, heated and molded in the form of a plate. The rate of compression in that time is required from the view point of moldability so that the final thickness is the half of the initial thickness or smaller. The heating temperature is generally desired to be 120-270 deg.C. Such execution of compression and heating unifies pieces of the asphalt foam into one body to obtain a board which is molded in the form of a plate. This is considered because the asphalt foam has a high viscoelasticity and the asphalt contained in the foam acts as bonding agent. This material is porous, excellent in acoustic absorptivity and sound arresting properties and suitable for floor material, wall material, other building materials, etc.
