Title: Consumable electrode type arc welding device
Inventor: AWANO YOSHIROU
IPC: B23K9/133
Filed: 1981-11-24
Abstract: PURPOSE:To stabilize arcs and to obtain uniform welding beads surely by providing a plastic working means for reducing the sectional area of a wire for electrode between a accommodating frame and a wire feeder. CONSTITUTION:A plastic working means 12 is disposed between a reel 1 and a wire feeder 3, and a wire 2 for electrode is plastically deformed in different radial directions by said means, whereby the sectional area thereof is reduced. The relative positions of the wire feeder 3 and the means 12 are so adjusted as to be linear when the wire 2 is delivered from a welding torch 8 and the wire 2 is fed by driving a driving mechanism 4. A contact member 9 and a pressing means 10 for feeding electricity to the wire 2 are disposed to the torch 8 and since the member 9 and the wire 2 are held in contact with each other forcibly, electricity is fed surely to the wire 2. In addition, the wire 2 is fed linearly and since the point of feeding of electricity is made approximately constant by such linear feeding, the arcs are stabilized.

Title: Method for measuring thickness of cover over sand layer
Inventor: NISHIKAWA YUTAKA
IPC: G01B5/06
Filed: 1987-07-30
Abstract: PURPOSE:To measure the thickness of cover over sand layer readily and accurately, by applying a vane testing method, capturing the amount of change in torque, which is generated in a rotary resistor, distinguishing the sand and viscous soil, and using the result for judgement. CONSTITUTION:A measuring instrument 1 is lowered to the bottom of water with a piece of rope 11. A seating plate 2 is seated on the surface of the layer of sand S. A motor 6 is rotated at a constant speed. An impeller unit 8 is rotated in the direction R at a constant speed. The impeller unit 8 is continuously pushed and inserted into the cover over a sand layer by the actions of gears 4 and thread rod 3 in the direction of the thickness T of the cover over the sand layer slowly at a constant speed as shown by an arrow D. The amount of change in torque, which is generated in the rotating impeller unit 8 at this time, is caught as the electric signal of a current value on a working ship 10. The signal is compared with the torque characteristic of standard cover over a sand ground. Thus the thickness T of the cover over the sand layer is determined.

Title: Transistor circuit
Inventor: SASAKI YUTAKA
IPC: H03B5/36
Filed: 1981-11-24
Abstract: PURPOSE:To decrease the power consumption of a bias circuit and to perform temperature compensation, by supplying a bias voltage of a transistor (TR) performing amplification or oscillation from the emitter of a TR of opposite polarity. CONSTITUTION:Since a PNP TR5 operates as an emitter follower, the impedance between the emitter and ground is low. Thus, even when resistance values of voltage division reistors 10, 11 determining the base bias of the TR5 are large, the impedance of the emitter circuit can be decreased. That is, the impedance between the base and ground of an NPN TR3 for amplification is low. Then, the bias voltage of the TR3 is made stable. Further, the influence of temperature can be decreased by setting the TR of opposite polarity as a bias voltage source.
