Title: Method for forecasting life of ball thread of motor- driven injection molding machine and device therefor
Inventor: TOTANI TSUGINOBU
IPC: B29C45/66
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To appropriately and certainly forecast the life of a ball thread by a simple arithmetic operation and at the same time, manufacture it with a simple structure at low cost. SOLUTION: This injection molding machine is structurally contrived so that the operation of a mold clamping device and an injection device is performed by an electric motor 16 under drive control through a ball and thread. In this case, the product of the transfer velocity of the ball thread 12 and the operating current of the electric motor 16 within a unit time is multiplied by the torque constant of the electric motor 16 to obtain a total energy value A to be applied to the ball thread 12. Then a life energy value B is established based on the product of a force generated in the ball thread 12 and the transfer velocity thereof, and when the total energy value A exceeds the life energy value B, it is (A>=B). Thus it is interpreted that the limits of the life of the ball thread 12 are established.

Title: Gradient-adjustable block
Inventor: SHIMIZU SHUNICHI
IPC: E02D29/02
Filed: 1994-03-14
Abstract: PURPOSE:To include slope structures having a gradient within a specified range by only one kind of block. CONSTITUTION:Legs 2, 3 which is high at the front side of a block body 1 and low at the rear side thereof, are provided at the bottom face of the block body 1 on which blocks for a retaining wall are stacked. By the legs 2, 3 of the block, a certain inclination can be set on a foundation plane. And hence, it is not necessary to finish a concrete foundation to provide gradient by a towel. And also it is useful for labor-saving and reduction of construction period. Even if the preset gradient is 5/60 deg., since the gradient-adjustable block is self- standing and stable, no other interpositions are required. After the block has been installed, a foundation concrete is placed and hence, the block is closely attached to the foundation and a theoretical structure can be obtained. Since the foundation and the arrangement of plinth stones in the stacking work of the blocks, can be carried out in one process, it can be constructed in about the half of days and labors necessary for the conventional method.

Filed: 1991-02-15
Abstract: PURPOSE:To measure the water level with high sensitivity without accompanying improper operation of the meter by reading the depth data recorded in a recording part of a metallic magnetic material mounted to a measuring plate by means of a bar code reader installed in a float body which moves up and down in accordance with the water level. CONSTITUTION:A sheet-like measuring plate 1 of a nonmagnetic material is mounted to the wall face of a weir 5 at right angles to the bottom of a river 4. A recording part 7 of the plate 1 records the data corresponding to the position of each depth in the form of bar codes. A float body 2 is formed of such a material that permits the float body 2 to float even if a bar code reader 3 is mounted thereon. The float body 2 freely moves up and down along a guide shaft 9. Therefore, the bar code reader 3 mounted on the float body 2 moving up and down in accordance with the water level magnetically reads the magnetic recording part 7 in which the data of the water level is recorded, so that the present water level recorded in the recording part 7 is detected. This apparatus is thus prevented from improperly operating and is capable of measuring the water level with high sensitivity.
