Title: Stern bearing structure
Inventor: YOSHIZAWA SHINICHI
IPC: F16C35/02
Filed: 1985-05-30
Abstract: PURPOSE:To make it possible to easily extract a boringless stern bearing using a resin material, by previously fitting an extracting heating coil into a resin charge section in the bearing so that the hardened resin is heated and softened by the energized coil. CONSTITUTION:A heating coil 4 is laid along the inner surface of a through-hole in the boss section of a stern keel beam 1, having its front end piercing through a part of the keel beam 1 and is connected to a heating coil connecting seat 5 which is arranged externally. During the process of repairing a ship, when it is required to extract a bearing 2 from the stern keel beam 1, the heating coil 4 generates heat to heat and soften a resin material by connecting a heating coil connecting seat 5 to the power source. Thereby it is possible to extract the bearing. With this arrangement, the hardened resin is unhardened, and therefore, the bearing may be easily extracted. With this arrangement no inner ring which incurs an increased initial cost is used to reduced the cost thereof.

Title: Method and device for automatic printing level detection of diazo copying machine
Inventor: ISHIMARU KENJI
IPC: G03B27/72
Filed: 1982-07-06
Abstract: PURPOSE:To perform automatic printing in diazo copying whose density is uniformed for vaiours originals by setting the interval of detection points for the light transmittivity of an original on the basis of the rate of variation in photosensitive paper printing sensitivity with the light transmittivity of the original. CONSTITUTION:When the front end of the original moves to between an optical fiber 14 and a photosensor 16, an original light transmission detecting circuit 40 detects the light transmittivity of the original. The circuit 40 consists of the photosensor 16, a transistor (TR) 42 for amplification, and N sets of comparators C1-CN, etc. The rate of variation in printing speed is high at a low- transmittivity part of the original, so the detection point interval is narrowed down; when the transmittivity increases, the detection interval is widened. The output signal of the circuit 40 regarding optimum original light transmittivity is passed through an A/D converting and holding circuit 54 and then respective circuits 56, 62, and 66, and the signal is inputted to a driving motor speed control circuit 70, which controls a driving motor 28 to control the printing speed of photosensitive paper, performing the automatic printing in diazo copying whose density is made uniform.

Title: Device of abnormal approach detection and collision prevention between torch and work in automatic welding machine
Inventor: TOWATA TOSHIYUKI
IPC: B23K9/12
Filed: 1979-09-10
Abstract: PURPOSE: To protect a torch from collision with a work without fail at the time of their abnormal  approaching by detecting an electrical state of a conducting material which is equipped on an  outer surface of a main body of torch, insulated from it, and impressed with voltage for detection,  wherein a torch is controlled in its relative position to a work.   
     CONSTITUTION: A conducting material 108 is mounted on an outer periphery of a main body 101  of a torch 3 through an insulating material 107 as an intermediate. In sensing, automatic welding,  or manual operation, a switch 201 (e) is always closed to impress the conducting material 108  with voltage for detecting an abnormal approaching. In the working of an automatic welding  machine, when a torch 3 abnormally approaches a protruding part W 1  of work W, electricity  passes through between the conducting material 108 and protruding part W 1  and is discharged, so the variation in voltage or current is detected by a electrical state detecting circuit 202b. Each  driving source of a welding device is stopped by the control means 5 through the signal "turn on  electricity" from an output circuit 202d of detecting electrical state. By this means, even though  spatter is filled up between a torch body and a tip, there will be no detection shown as a state of  turning on electricity.
