Title: Msis type semiconductor element
Inventor: SEKIKAWA TOSHIHIRO
IPC: H01L27/00
Filed: 1980-07-09
Abstract: PURPOSE:To easily form the constituents for the subject semiconductor element by a method wherein a semi-insulating film having the same crystalizing property as a substrate is used for the constituents corresponding to the insulating film on the substrate. CONSTITUTION:A source and a drain regions 3 and 4 are separately provided in the vicinity of the surface of the substrate 1, a channel region 2 is located between the source and the drain, a gate electrode 6 is provided on the region 2 through the intermediary of a thin film 5 and electrodes 7 and 8 are attached to the source and the drain regions respectively. The thin film 5 below the electrode 6 consists of a semi-insulating film of GaAs, for example, having the same crystalizing property as the substrate 1, instead of the conventional insulating film.

Title: Tube feeder
Inventor: OKAMURA SHIGERU
IPC: B65G11/02
Filed: 1989-04-13
Abstract: PURPOSE:To effectively deliver chips one by one to a receiving material and to feed it to a takeup position by a transfer head by providing a chip drop preventing unit for preventing the chip disposed at the lowermost part of a tunnel unit from dropping. CONSTITUTION:A chip drop preventing unit 60 is driven by the same cylinder 56 as a receiving member 43, and operated synchronously with the reciprocation of the member 43. That is, when the material 43 is disposed at the receiving position, a stopping state with a pin 63 is released, and a chip P is slid to the material 43 to be delivered. When the material 43 is separated from the lower end of a tunnel body 4 to a takeup position, the pin 63 is raised to prevent the chip P of the lowermost part from dropping. Thus, the hitting of the tube, the reciprocating of the material 43 and the drop preventing of the chip P are conducted by the driving of the same cylinder 56, thereby accurately synchronizing the operations. Thus, the chip contained in the tube can be effectively fed to the takeup position of the head.

Title: Rope pulling device
Inventor: UJI TSUGUO
IPC: A63B71/02
Filed: 1989-04-13
Abstract: PURPOSE:To enable more than three teams to simultaneously enjoy a tug of war by providing one ring to be freely deformed on one panel, three pairs of rollers at least to be fixed to a panel, which guides the outside and inside of the ring, and three pulleys at least to which a rope for the tug of war can be fitted, to be freely moved on the panel along the ring although the pulleys are stricted to the ring. CONSTITUTION:Four pulleys 4 are stricted to a ring 2, however, these pulleys 4 can be freely moved on a disk 1. A rope 5 for the tug of war is fixed to the pulleys 4 and guided by rollers 6, which are fixed to the disk 1, to guide the rope 5 for the tug of war totally at intervals of 90 deg. for four participating teams. When the rope 5 for the tug of war is pulled, the pulley 4 is closed to the circumference of the disk 1. Since the pulley 4 is stricted to the ring 2, the ring 2 is attracted in proportion to the moving length of the pulley 4 in a diameter direction. Since the whole length of the ring 2 is not changed, the other pulleys 4 are attracted toward the center of the disk 1. Accordingly, the mutual relation of pulling force for the four teams can be simultaneously compared.
