IPC: A63C9/20
Filed: 1985-10-23
Abstract: A cross-country ski binding for use with a ski boot having a front extension portion on its sole, with the front end portion providing a hooking area on its top surface, has a double-armed retaining lever whose arm which faces towards the rear of the binding forms a hook for engaging behind the hooking area on the extension portion of the boot. The second arm of the retaining lever can be secured in the closed position of the binding by a locking lever pivotally mounted at the front end of the binding. The locking lever is spring-loaded towards the position of locking the retaining lever in the closed condition of the binding. The binding also has a release button which is disposed pivotally coaxially with respect to the retaining lever and which is limitedly pivotable relative to the retaining lever, against the force of a retaining spring, thereby to displace the locking lever into a position for releasing the retaining lever. The retaining lever also has an abutment which is engaged by the first extension portion of the boot upon insertion thereof into the binding to pivot the retaining lever into the binding-closing position.

Title: Rotary forging method for annular sintered alloy body
Inventor: EBIHARA TADASHI
IPC: B21J9/02
Filed: 1985-10-25
Abstract: PURPOSE:To improve a yield of a raw material and to reduce machinings by forming an outside surface of an annular die groove to be vertical and forming an inner diameter of a lower end side larger than that of an upper end side at an inside surface, further by forming the center relief of upper die to be a reversely tapered cavity. CONSTITUTION:The upper die 40 is formed conically of its bottom surface 41 and in its center, the reversely tapered cavity 42 of expanded inner space is provided. An annular sintered alloy body 50 is inserted into the annular die groove 10 to ascend the die 20 and the lower die 30 and a projection 34 of the lower die is inserted into the hollow 42 of the upper die. The upper die 40 is rotated swingingly and at its lower surface 41, the upper surface of the alloy 50 is locally pressed uniformly to the cold forged. After the forge is finished, the die 20 and the lower die 30 are lowered to detach the alloy body 50 from the upper die 40, then the lower die 30 is ascended to pull out the alloy body 50 from the die 20. As the surface of outer periphery is released, so the alloy body 50 is slightly expanded by its spring back and its outside diameter becomes larger than the inside diameter of the die 20. In this way, the alloy body 50 is forged to form equal to a finished product or nearly equal to it, and to eliminate the machining after the forging.

Title: Water tank for rearing seeding
Inventor: TOYAMA ISAO
IPC: A01K61/00
Filed: 1989-09-12
Abstract: PURPOSE:To obtain a water tank for rearing seedling capable of carrying out control of discharge port without inserting a hand in water owing to control of water level, etc., by constituting water tank so as to rotate an inner tube for water discharge in an outer tube and discharge water when discharge holes of the both tubes provided in same height level coincide. CONSTITUTION:Water is fed into a water tank body 1 and corresponding holes of both tubes are allowed to coincide by rotating an inner tube 82 using each water discharge means 8. For example, when a hole 81a is allowed to coincide with a hole 82a, water level 90 is kept constant by floating water from the both holes to discharge water. A prescribed amount of teed is fed from an automatic feed device 3 installed on a section in this state. When the water level 90 is changed to height of the holes 81b and 82b or the holes 81c and 82c, upper end part of the inner tube 82 is held from above a main body 1 and rotated to allow the hole of inner tube 82 to coincide with the hole of outer tube 81. It can be prevented to exert bad influence on fishes in this time, because it is not required to insert a hand in the water tank.

Title: Multiplex data program organization system
Inventor: SASAKI TETSUO
IPC: H04H20/42
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To effectively use a broadcasting radio wave and to facilitate data multiplex broadcast program organization. SOLUTION: A packet (dummy packet) without data to be broadcast, which is generated in data multiplex broadcasting, can effectively be used as a transmission channel resource. A private logic channel identification 2-code is used for the dummy packet, data of program guidance is inserted and a user selects it so as to use it. A data multiplex broadcast program (filler packet) broadcast by a packet (filler packet) used as such transmission channel resource can arbitrarily cyclically and repetitively broadcast or can be broadcast only for one time. A reception device automatically receives the packet to which the private logic channel identification 2-code is added and can take in the data. When the user does not select the specified program and the reception device in a standby state, data can automatically be displayed and push-type data multiplex broadcast can be executed.

Title: Control gate driver circuit for non-volatile memory and memory using it
Inventor: MORTON BRUCE L
IPC: G11C16/02
Filed: 1997-08-19
Abstract: PROBLEM TO BE SOLVED: To realize a control gate driver circuit which operates in a wide range of voltage and furthermore minimizes the area of integrated circuit. SOLUTION: The control gate driver circuit 900 supplies a variety of voltages to the gate of a floating-gate non-volatile memory cell 10 using a single circuit. At the time of readout, a bias circuit 920 and a reference transistor 925 biases the gate of a pass transistor 936 connected to the output of a level shifter 910 so that the transistor 936 may become slightly conducting without using a charge pump. At the time of programming, a pulse circuit 940 gradually raises the program voltage being supplied to the cell accompanying the selector row and allows smaller transistors 932, 934 and a smaller capacitance of the charge pump to use. The cell of the non-selection row is driven at a different voltage, reduces the junction leakage and maintains a high disturbance voltage against the cell of the non-selection row.
