Filed: 1988-06-29
Abstract: PURPOSE:To make a washing state satisfactory by drilling nozzle holes with liquid ejection directions which are set obliquely backward, at right angles and obliquely forward respectively at different positions from each other in the axial direction of a nozzle head and radially on the axial vertical across-section of the head. CONSTITUTION:An ejection direction changeover cylinder 3 moves compressing a spring 4 in a liquid flow direction.

In addition, if the pressure is increased and thereby the changeover cylinder 3 compresses the spring 4 to form a flow path with a nozzle holes (b) and the holes in the changeover cylinder 3, the liquid is ejected in the direction of the nozzles (b) located at right angles to wash and clean the interior of the piping. If the pressure is further increased in the same manner, and nozzle holes (c) and the holes in the changeover cylinder 3 form a flow path, the liquid is ejected obliquely forward to wash and clean the interior of the piping. Outflow and inflow perforations 5 allow the liquid in a spring 4-loaded chamber to flow out and in by action of the changeover cylinder 3 to exclude any faulty action.

Title: Current detector
Inventor: WAKAO NAOKI
IPC: G01R19/165
Filed: 1990-06-20
Abstract: PURPOSE:To prevent a residual voltage from being generated and to improve the detection accuracy of a current by providing a residual voltage adjusting resistance and a temperature characteristic correcting circuit and performing adjustment or correction against the temperature variation of a magnetism sensing element so that the residual voltage is reduced to zero. CONSTITUTION:When the magnetism sensing element 3 is at specific temperature, variable resistances VR1 - VR4 adjust the residual voltage in the detection signal of the element 3 to 0. Further, resistances R7 and R8 and diodes D1 and D2 connected in series between 1st and 2nd power terminals T1 and T2 form the temperature characteristic correcting circuit and when a current of less than several mA is supplied to the diodes D1 and D2 having forward and backward temperature voltage characteristics, a voltage VD1 varies by +2mV/ deg.C and the voltage VD1 varies by -2mV/ deg.C. Those values are constant and when a variable resistor VR5 > VR6, the influence of VD2 upon VD1 increases to have positive temperature characteristics; when VR5 < VR6, the influence of VD1 upon VD2 increases to have negative temperature characteristics, thereby reducing the residual voltage of the detection signal inputted to a voltage amplifier 5 almost to 0.

Abstract: PURPOSE:To contrive uniforming of voltage caused in each division winding wire to improve reliability by making division winding of a secondary winding wire and increasing the winding number of each division winding wire in which nearer to the gap of a core the winding number is, the more it is. CONSTITUTION:Cores 6, 7 in which gaps 8, 9 are provided in a magnetic path are provided, because a high tension transformer lowers coupling coefficients of a primary winding wire 2, a secondary winding wire 10 and the primary winding wire 2 and the secondary winding wire 10. The winding wire 10 is split-winded on a secondary bobbin 3. Each split winding wire 10a-10e has a more winding number, nearer to the gap 9 of the core 10 it is. Thereby voltage- proof design of the winding wires 10a-10e is performed on same reference because the voltage induced in the winding wires 10a-10e is approximately equal. Thereby the improvement of reliability can be contrived.

Abstract: PURPOSE:To embody the labor saving by taking out a raw tire with a high efficiency while giving marks, and also simplifying the structure. CONSTITUTION:The working efficiency is improved by effecting an approaching and separating action of a mark giving member 38 to a raw tire T by an approaching and separating means 44 in simultaneously with the approaching of grasping means 21 to the raw tire T by a cylinder 25 and the grasping operation of the raw tire T by the grasping means 21. Also, an operator is not required to the mark giving operation, and therefore labor-saving is achieved. Further, since the mark giving member 38 and approaching and separating means 44 are secured on the grasping means 21, these are not necessary for interference prevention to be withdrawn at the time of shifting the grasping means 21, thus, the structure is simplified.
