Title: Method and device for die casting
Inventor: KAWAGUCHI MASATOSHI
IPC: B22D27/04
Filed: 1987-01-12
Abstract: PURPOSE:To prevent hot cracking of a casting and damage of a die by subjecting the casting surface layer in the die to quick cooling after pouring and parting the die at the point of the time when a shell-like solidified layer is formed. CONSTITUTION:The die 1 is constituted of a 1st die and 2nd die 22. Heating circuits 8 having bar-shaped heaters 12 and cooling circuits 9 consisting of introducing paths 14, drain paths 15 and communicating paths 16 are disposed to the respective dies. The die 1 is heated to and held at the prescribed temp. by the heating circuits 8 according to the respective parts of the casting before pouring the molten metal and the molten metal is poured into the die through a sprue 3. The heating of the diel is then stopped and the cooling by the cooling circuits 9 is simultaneously started. The surface layer of the casting is quickly cooled. The die parting is executed at the point of the time when the shell-like solidified layer is formed on the surface layer upon falling of the surface layer temp. down to the prescribed temp. or below. The surface layer of the casting is thereby formed as the normal solidified layer, by which the hot cracking is prevented and the damage of the die arising from the deformation of the casting is eliminated.

Title: Picture reading device
Inventor: ARAO KOUZOU
IPC: H04N1/03
Filed: 1980-01-21
Abstract: PURPOSE:To ensure a highly efficient positioning of an image sensor, by inverting the image of the bright/dark identifying mark provided in a body with the image sensor against the optical axis to project the image onto the image sensor and detecting the variation of output according to the degree of deviation to the optical axis to give a minute shift to the identifying mark. CONSTITUTION:The reflecting plates 8a and 8b are provided right before the image sensor 4 in such way that the edges of the reflecting plates become parallel to the array direction of the sensor's light receiving parts. These reflecting plates are irradiated by the lamps 9a and 9b, and the reflected light enters the image forming lens 3. The plates 8a and 8b become bright; while a dark part is formed at the slit-shaped region having a longer direction vertical to the paper surface and formed by the gap between the reflecting plates. Now if the sensor 4 is at the normal position in terms of the (v) direction, a coincidence of the image is obtained between the plates 8a and 8b. Thus the regular incident light volume does not exist at the light receiving part of the sensor 4, and only the bias component is delivered there. As a result, a highly efficient positioning is possible for the image sensor by fixing the sensor at the position where the output becomes minimum.

Title: Electromagnetic type fuel injection valve
Inventor: SOMA MASAHIRO
IPC: F02M51/06
Filed: 1987-01-16
Abstract: PURPOSE:To obtain a fuel injection valve which possesses the stable fuel injection function by constituting the armature side guide part of a movable element from a slidable member which is made of nonmagnetic material and installed between an armature and a core and allowing a valve piece to correctly coincide with the axis center of the valve. CONSTITUTION:A ball valve is guided by the center guide hole of a valve guide 7, and guided by a guide ring 36 which is made of nonmagnetic material and installed between a core 2 and a plunger 4 installed through a rod 5 on the opposite side to the ball valve 6. Therefore, even if a movable part is formed small and lightweight in order to spread the dynamic range, the distance between the guide parts can be set sufficiently long without increasing the whole length of the valve, and the shift in the axial direction of a movable element can be allowed to coincide correctly with the axis center of the valve. As the result, the problem of loosening reproducibility due to the tilt and shift of the movable element and the one side contact phenomenon of the ball valve 6 onto a seat surface 8 can be eliminated, and the stable fuel injection function can be obtained.
