Title: Navigation system
Inventor: ITO YASUO
IPC: G01C21/00
Filed: 1999-10-15
Abstract: PROBLEM TO BE SOLVED: To obtain a navigation apparatus which guides a vehicle in such a way that a degree of importance with reference to a point, to be guided, in a set running route can be recognized. SOLUTION: When a vehicle advances straight on a crossing, to be guided, without changing a course according to a guide, the degree of importance of the crossing is judged on the basis of the increase amount of costs (the increase amount of a running distance). Then, a warning sound before the output of a guide voice is made longer and larger the higher the degree of importance of the crossing to be guided is, and the guide voice is output in a large sound volume. In addition, when a crossing detailed figure in which the crossing to be guided is expressed in detail is displayed by an image, a route part is displayed in a more noticeable color (e.g. in a red color) the higher the degree of importance of the crossing is. Thereby, a driver can recognize the degree of importance of the crossing, to be guided, on the basis of the guide voice or the display image.  In the case of the crossing whose degree of importance is higher, the driver can change a course more surely to a guide direction. In addition, since the driver is not restrained by a guide in all crossings to be guided, a feeling of strain with reference to the output of the guide voice can be reduced.

IPC: B65H29/70
Filed: 1996-11-07
Abstract: PROBLEM TO BE SOLVED: To improve discharge performance of a sheet and loading performance on a tray by arranging first and second projecting parts each in the circumferential direction at both end parts of a first roller in width direction, and making the first projecting part more easily deformable than the second projecting part. SOLUTION: A rubber flange (a first projecting part) 1d is integrally formed in an end part of a rubber paper discharge roller (a first roller) 1a fixed at a prescribed interval to a driving shaft 2. A resin flange (a second projecting part) 1b is integrally fixed to the paper discharge roller 1a. The rubber flange (the first projecting part) 1d is more easily deformed by external force than the resin flange (the second projecting part) 1b, and is easily deformed by being pushed by a passing sheet. When viewed from the rotary shaft direction of these flanges, since pushing-out surfaces to push out the sheet by engaging with a sheet rear end part are formed at prescribed intervals in the circumferential direction, the discharge performance of the sheet can be improved.

Title: Optical waveguide and its manufacture
Inventor: SEMURA SHIGERU
IPC: G02B6/122
Filed: 1989-11-14
Abstract: PURPOSE:To reduce radiant loss at a curvature part by preparing an optical waveguide formed with a substrate and a metallic element diffused in the substrate according to a desired pattern, and further diffusing an MgO in the curvature part of an optical waveguide pattern and the area of the substrate in the neighborhood of the curvature part. CONSTITUTION:The optical waveguides are the waveguides 4a, 4b formed with the substrate 1 and the metallic element diffused in the substrate 1 according to the desired pattern, and the MgO is diffused in the curvature part of the optical waveguide pattern and the substrate 1 in the neighborhood of the curvature part. For example, MgO layers 6a, 6b are formed at the curvature parts of the optical waveguides 4a, 4b formed by applying the thermal diffusion of Ti to the substrate, and the thermal diffusion is applied, and the MgO is diffused only in the neighborhood of the curvature parts of the waveguides 4a, 4b. When the MgO is further diffused in the optical waveguide in the substrate 1 and the neighborhood of the waveguide, a refractive index is decreased in an area where the MgO is diffused, and the radiant loss can be reduced compared with an ordinary optical waveguide in which only Ti is diffused. Thereby, it is possible to reduce the radiant loss at the curvature part and to form the optical waveguide with uniform radiant loss in spite of the inclusion of the curvature part.

Title: Voice packet communication system
Inventor: SUZUKI MUNEYUKI
IPC: H04L12/00
Filed: 1988-11-22
Abstract: PURPOSE:To minimize deterioration in voice quality attended with overrun due to fluctuation delay by sending information while time information corresponding to an interblock length from the transmission of a preceding talk's part till the transmission of the succeeding talk's part to a burst head representing the start of the talk's part. CONSTITUTION:A time data representing a transmission time interval t3 between a talk's part 1 and a talk's part 1' is written in a burst head 3. When the receiver side detects a burst head 3 from the received talk's part 1', a time data t3 representing the length of the interblock between the talk's parts 1, 1' at the sender side and the time data t3 is compared with an actual counting time (t4+t2) requiring the reception of the proceeding talk's part 1 till the present talk's part 1' is received. When the time (t4+t2) is shorter than the time data t3, the receiver side continues the time counting further and the reproduction of the talk's part 1' is started after the time t3 is elapsed. Thus, the deterioration in the voice quality attended with the overrun caused by the delay of fluctuation is minimized.
