Title: Method of forming traversal non-slip streak on frozen road surface, and traversal non-slip streak forming device
Inventor: ABE TADAMASA
IPC: E01C23/085
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To efficiently form a traversal non-slip streak for preventing the wheel slip of a traveling vehicle by elastically pressing a coining tooth member installed to a self-traveling vehicle onto a frozen road surface, and releasing the elastic pressing at a required timing. SOLUTION: A coning tooth member 1 long in the road width direction is installed to the rear chassis S of a self-traveling vehicle T through a tooth rocking beam 11, and the coining tooth member 1 is elastically pressed onto a frozen road surface R by a hydraulic cylinder 2 through an elastic pressing member 3 formed of a compression coil to form a traversal non-slip streak. As an elastic pressing releasing means 4, a roll cam 41 is rotated by a hydraulic motor to intermittently bring up the tooth rocking beam 11. Thus, the rotating speed of the hydraulic motor is synchronized with the advancing speed of the self-traveling vehicle T, whereby the traversal non-slip streaks can be efficiently formed at prescribed intervals on the frozen road surface R.  The form of the coining tooth member 1 is changed, whereby non-slip streaks of square tooth form, oblique tooth form and the like can be formed.

Title: Manufacture of positive electrode container for sodium molten-salt secondary battery
Inventor: TAKEDA YASUYUKI
IPC: H01M10/39
Filed: 1994-03-14
Abstract: PURPOSE:To improve corrosion resistance of a container, and prevent deterioration of battery performance by flame coating W to a surface of a Cr plating layer provided on an inner surface of a positive electrode container of Ni, providing an Ni-P plating layer on the surface, applying heat treatment, and forming a mutual diffusion layer between Ni and flame coated W. CONSTITUTION:A Cr plating layer 10mum thick is formed on a surface of an Ni base material for a positive electrode container for a sodium molten-salt secondary battery in an electroless plating method. Flame coating of W about 80mum thick is formed on the surface using a beam exposure flame coating method. Next, it is heated at 900 deg.C for 5min., in a vacuum heating furnace. An Ni-P plating layer on the surface of the W flame coating is fused by heat treatment to invade inside through pores in the W coating to close the pores. Ni-P invading into the coating is mutually diffused with the W coating to form a dense coating. In addition, the Cr plating layer provided between the W coating and the positive electrode container material restricts diffusion of the positive electrode container material (Ni) to the W coating properly, so diffusion void generated in the positive electrode container is prevented, while diffusion layers with the positive electrode container material, Cr plating layer, and W coating are generated, thereby adhesion of the coating can be improved.

Filed: 1991-02-15
Abstract: PURPOSE:To enable a customer to easily take out and visually recognize coins to prevent unexpected drop of coins by raising coins which are temporarily dropped and guided from a coin mechanism to the lower part of a vendor. CONSTITUTION:Coins temporarily guided to the lower part of the vendor from the coin mechanism through a guide chute 14 are raised to the upper part of a coin taking-out hole 8 together with a coin reception box 48 by an elevating means 32 after being received by the coin box 48. Coins in the coin reception box 48 are guided to the coin taking-out hole 8 by guide means 48c and 50. Since the coin taking-out hole 8 can be arranged in a relatively high position of the vendor in this case, it is arranged in such position that the customer can easily visually recognize and take out coins. Since the exit of the guide chute 14 is closed by a closing means when the coin reception box 48 is separated from the reception position, coins are prevented from being unexpectedly dropped to the inner bottom part of the vendor.

Abstract: PURPOSE:To grasp a broadcast channel of a teletext immediately by scanning each channel when a channel selection circuit does not implement channel selection for reception so as to detect a broadcast channel of the teletext and storing the channel in a storage device. CONSTITUTION:A microcomputer 4 supplies a channel selection signal selecting sequentially each channel of an RF signal for a prescribed period such as standby to a channel selection circuit 2 and a video signal of each channel is inputted to a teletext processing circuit 3, which outputs a detection signal representing whether or not a teletext signal is multiplexed on a video signal of any channel to the microcomputer 4. Then the microcomputer 4 generates a display data relating to a broadcast channel of the teletext from the detection signal and stores the data in a storage device 7. The display data is read by the user operation and the display representing the broadcast channel of the teletext is displayed on a display device 5. Thus, the channel through which the teletext is broadcast is immediately grasped without any troublesome operation.

Filed: 1983-03-14
Abstract: PURPOSE:To obtain a medium having an excellent frequency characteristic and sensitivity over the entire frequency band by laminating and forming successively a triple magnetic layer including metallic magnetic powder on a base and adopting a prescribed value of coercive force for each layer. CONSTITUTION:The triplet magnetic layer including metallic magnetic powder is provided sequentially by lamination on the base, the coercive force of the intermediate magnetic layer is taken as 1,100-1,300 oersted and the coercive force of the lowermost magnetic layer is decreased by 100-200 oersted less than the coercive force of the intermediate magnetic layer. Then, the coercive force of the uppermost magnetic layer is increased by 100-200 oersted more than the coercive force of the intermediate magnetic layer. Thus, the deterioration of the frequency characteristic at medium frequencies is avoided because of decrease in the frequency characteristic at medium frequencies, the excellent frequency characteristic and sensitivity are obtained over the entire frequency band and further, noise is reduced sufficiently.
