Filed: 1986-03-20
Abstract: PURPOSE:To obtain an ingot having no component segregation by specifying the relation among the number of gate holes, the minimum diameter of the hole, the shape of the opening part and the relation between the distance from the hole center to the mold inner wall and the distance from the mold center to mold inner wall of a molten metal distributor. CONSTITUTION:The number N of gate hole 2 is taken >=3 pieces, the diameter (d) of the minimum part of the hole 2 in the range of 3-15mm and the opening part of the hole 2<=700mm<2> upper limit value of d<2>N, on a molten metal distributor 1. The distributor 1 is made so that the horizontal distance 9 from the center position of the hole 2 upto the mold inner wall 10 becomes <=2/3 of the horizontal distance from the mold center 7 passing through the center position of the hole 2 upto the mold wall 10. The melted molten metal is thus cast to a mold 4 from each hole 2 by pouring it to the distributor 1, and the generation of a shrinkage cavity accompanied by the solidification shrinkage is prevented by filling up the molten metal in a feed head frame 3. In this way the ingot with uniform distribution of the alloy element without component segregation can be manufactured.

Title: Label attaching device
Inventor: TOKURA HIROAKI
IPC: B65C9/36
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To surely attach a label to a prescribed position by connecting a label receiving and supporting member to receive to receiver the label to a tip of a moving member through a closely coiled spring member to converge the vibration of the spring member to be generated after a commodity is abutted on the receiving and supporting member in a time as early as possible. SOLUTION: A pressing member 42 having a pressing part 42a formed of a flexible synthetic resin such as a rubber is fitted to a lower end part of a push rod 40 through a closely coiled helical spring 43. Because the closely coiled helical spring 43 is used to connect the push rod 40 to the pressing member 42, the pressing member 42a follows the movement of a commodity while the pressing part 42a presses the label against the commodity and attaches it thereto, and the label can surely be attached without breaking a film of the commodity. Further, because the pressing member 42a is formed of a flexible synthetic resin such as a rubber, the impact when the pressing member 42a is abutted on the commodity can be absorbed.

Title: Oscillator
Inventor: TAKAHASHI KUNIHIRO
IPC: H03H9/19
Filed: 1980-05-12
Abstract: PURPOSE:To obtain two independent stable oscillations having high Q value, by making a single oscillation of a pair with two external tuning fork and making an independent oscillation from the oscillation by both the forks, by means of the center fork. CONSTITUTION:Forks 7, 9 make a single oscillation as a pair, and a fork 8 makes an independent oscillation from the oscillation of the forks 7, 9. Further, the oscillation of the forks 7, 9 is the symmetrical oscillation with respect to a cross-section 10, which is a node of oscillation to this oscillation. Thus, the oscillation of the forks 7, 9 is a stable oscillation in which the oscillator utilizes the shape of tuning fork and sufficiently higher Q value is given. Further, the oscillation of the fork 8 at the center can be approximated to the oscillation of a cantilever simply. Thus, a tuning fork oscillation having three forks 7-9 like this is excellent in small sized oscillator and mass production, allowing to pick up the two independent stable oscillating mode having higher Q value.

Filed: 1989-03-15
Abstract: PURPOSE:To reduce in size and to prevent a printing quality from deteriorating by providing a supporting member for preventing a rotor from deflecting by tension of a stripe plate. CONSTITUTION:A supporting member 20 for supporting rotors 12, 12 is provided between both the rotors 12 and 12. Thus, the member 30 can prevent the rotors 12, 12 from deflecting. As a result, a stripe plate 14 is not slacked and not floated from a printing base 11, thereby improving a printing quality. Since it is not necessary to increase the diameter of the rotor 12, a printer can be reduced in size. Since the plate 14 is prevented from obliquely feeding, a decrease in the printing quality and a jam, etc., can be prevented. The member 20 is formed in a state having a slide contact face 23 for rotatably supporting the rotors 12 on both side faces 21, 22 and an opening 24 for containing a printing base 11 to further strengthen a deflection preventing force of the rotor 12 of the member 20.
