Title: Slide joint for drive shaft
Inventor: SUZUKI MORIO
IPC: F16D3/205
Filed: 1986-03-24
Abstract: PURPOSE:To reduce the longitudinal vibration of a vehicle body, by enlarging an axial sliding resistance between a joint input member and a joint output member, and canceling a change in same phase toe angle of right and left wheels with each other. CONSTITUTION:While a joint input member 21 and a joint output member 22 are axially relatively moved in a contracted position of a slide joint from a normal position, an axial sliding resistance between both the members 21 and 22 is enlarged. During stopping a vehicle with an automatic transmission shifted in a drive range where the axial relative movement is generated, right and left drive shafts 5 are mutually axially cooperated with each other by an increase in the axial sliding resistance, thereby canceling a change in same phase toe angle of wheels to be generated by a creep torque during stopping of the vehicle. Accordingly, a toe angle of the wheels is slightly changed in reverse phase, thereby greatly reducing the longitudinal vibration of a vehicle body.

Title: Method for regenerating used cast sand
Inventor: RUDOBUITSUHI BUIRUHERUMU
IPC: B22C5/10
Filed: 1991-03-07
Abstract: PURPOSE: To enable the reconditioning treatment for reusing one batch of the clay bonded used molding sand by holding the optimum relation between the volume of a drum and the sand amount. CONSTITUTION: The used molding sand is charged into the drum and whole circulating around the horizontal axis, the molding sand is separated into the send grain and outer shell part burnt and hardened. The outer shell part separated from the sand grain is formed as dusty grain in the result of friction action and discharged together with the air during treating. The decreasing amount generated in this result is compensated with the weight or the volume by adding the suitable amount. Therefore, the friction of the sand grain during botch treating, i.e., the separation of the outer shell part in the sand grain is kept to the constant.

IPC: G02B6/00
Filed: 1979-05-28
Abstract: PURPOSE: To safely transport heat energy and make the work easy by transmitting the light of the infrared region produced by the combustion of fuel by light transmitting media.  
     CONSTITUTION: Fuel is burned by a combustion device 1 such as burner and the light of an infrared region is produced by the heating thereof in a heat-light converter 2 by way of zirconia or the like. This light is condensed by a condenser 3 such as condenser lens or concave mirror and is transmitted to a heat utilizing device 5 by an optical fiber 4.

IPC: F02M61/18
Filed: 1981-05-06
Abstract: PURPOSE:To improve the accuracy of injection nozzle by piercing a nozzle needle section with an electron beam or similar means from outside the nozzle and at the same time boring a hole as an injection nozzle under the state where a heat-treated nozzle body and a nozzle needle are assembled. CONSTITUTION:Boring work of injection nozzle is performed by radiating an electron beam 4 to a nozzle 1 and a nozzle needle 2, which extends to a main current 3, from outside the nozzle 1 under the state where the heat-treated nozzle 1 and the nozzle needle 2 are assembled. A measurement fluid is introduced into the main current channel 3. The cross section area for the first nozzle, which responds to the flow rate (QT/n=q1), is computed out of the flow rate QT, injection nozzle number n, and command signal S for the cross sectional configuration of nozzle that have been introduced into microcomputer 9. The signal which sequentially deflects the electron beam 4 by the computed main scanning width and subscanning width, is output toward a control unit 6 sequentially. With this construction, an electrom beam boring unit 7 bores a hole as the first injection nozzle in response to the signals.
