Title: Cylinder fuel injection device
Inventor: OKAMOTO YOSHIO
IPC: F02M61/18
Filed: 1999-02-08
Abstract: PROBLEM TO BE SOLVED: To provide a spray of a solid flat shape by forming a plurality of recessed passageways in an area between a position of a valve seat portion against which a valve member collides and an inlet portion of a fuel injection orifice whose cross section is an oval shape, while making fuel outlet portions of the recessed passageways to be open facing to each other inside the fuel injection orifice. SOLUTION: Recessed passageways 25 are provided in areas between a cylindrical fuel circulating member 22 and a seating surface 9, and an oval-shaped fuel injection orifice 8. Outlet portions of these recessed passageways 25 are made to be open facing to each other at an inlet portion of the oval-shaped fuel injection orifice 8. According to this construction, fuel flows through an axial passageway 23 and radial passageway 24 to reach a fuel sump chamber 26. It further moves toward the oval-shaped fuel injection orifice 8 via recessed passageways 25 in which a swirl faces each other. The fuel, which has moved past the radial passageways 24, collides with another charge of fuel at the inlet portion of the oval-shaped fuel injection orifice 8 as it flows through the opposing recessed passageways 25 downstream. It is then bent and diffuses as it moves further downstream.  This makes the shape is of a spray into a solid form and makes its cross section flat.

Title: Optical waveguide array and its production
Inventor: KONDO HIROMI
IPC: G02B6/13
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To provide an optical waveguide array which is formed with a continuous region where a refractive index change and a decrease of intrinsic absorption are induced by condensed irradiation with a pulse laser beam in the inside part of a glass material. SOLUTION: The interior of the glass material 7 contg. metallic particulates, semiconductor particulates, transition metal ions, rare earth ions, anion, etc., having the intrinsic absorption in a wavelength range longer than 360 nm is condensed and irradiated with the pulse laser beam 5 adjusted in its focal point 6. The change region where the refractive index change and the decrease of the intrinsic absorption of the wavelength region longer than 360 nm are induced is thereby continuously formed in the glass material 7. The change region has the greatly different optical characteristics between the non-condensed and irradiated part and the non-changed region and is, therefore, used as an optical waveguide.

Title: Ultrasonic image pickup method and its device
Inventor: TAKEUCHI YASUTO
IPC: A61B8/06
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To execute image pickup by a second higher harmonic echo without being effected by a folding phenomenon by stopping the utilization of the second higher harmonic echo in the state of generating aliasing in the second higher harmonic echo. SOLUTION: As for a basic wave echo, if the time change of a Doppler shift like this e.g. is obtained, the Doppler shift exceeds +pulse repeating frequency(PRF)/4 in a period P and becomes within ±PRF/4 in the other period. At this time, as the Doppler shift of second higher harmonic echo becomes twice as large as the Doppler shift of the basic wave echo concerning a same flow rate, the period change of the difference exceeds +PRF/2 in the period P and folding by aliasing is generated on the side of -PEF/2. Thereby, the second higher harmonic echo in the period P is not suitable for utilizing it as a signal expressing the flow rate. Then, in the period P, namely in a period in which the Doppler shift of the basic wave echo exceeds 1/4 of the PRF, Doppler image forming based on the second higher harmonic echo is invalidated.

Title: Heat-mode recording method
Inventor: HANADA HIROSHI
IPC: G11B7/24
Filed: 1984-02-20
Abstract: PURPOSE:To enable heat-mode recording with high practicability, by a method wherein a recording layer as a whole is provided with a relectance more favorable than that of a thin metallic layer alone, the recording layer is irradiated with light of a specified wavelength, and the irradiated part of the recording layer is removed by melting. CONSTITUTION:As compared with the case where a thin metallic layer or a thin non- metallic layer is used solely as a recording layer, sensitivity is expectedly enhanced largely by using an appropriate laminate of both of the thin layers as a recording layer and irradiating the recording layer with light of a specified wavelength. The heat of evaporation of the non-metallic layer is aproximately equal to or smaller than that of the metallic layer, and the non-metallic layer itself is easily removed by heating, so that the non-metallic layer does not excessively hinder the metallic layer from being removed through melting by absorbing the optical energy of light with which it is irradiated, and recording with high sensitivity can be achieved. It is necessary that a material used for the non-metallic layer can be formed into a thin film having a thickness of not larger than 1mu, and when it is laminated with the metallic layer, the surface reflectance of the resultant recording medium to a specified wavelength can be reduced to or below 1/2 of that of the metallic layer alone, by appropriately selecting the film thicknesses.

Filed: 1992-02-18
Abstract: PURPOSE:To prevent loss of packet transmission data generated in the asynchronizing state by stopping the transmission of packet data till synchronization is established when a ring is in the asynchronizing state in a hybrid mode. CONSTITUTION:In a multi-medium LAN in which line exchange data and packet data are communicated through the same transmission line as a transmission medium, a synchronization success discriminator 11 discriminates the success of the synchronization of the ring and when the synchronization is not established, the transmission stop of the packet data is requested to a packet medium access controller 7 till the synchronization is established. The synchronization is referred to as a state that a station (cycle management station) controlling the ring synchronization in existing exclusively on a transmission line continues the transmission of a specific frame called a cycle for each prescribed period without causing duplication and intermission. Thus, loss of packet transmission data caused when the synchronization is not established is avoided.
