Title: Injection molding method and its device
Inventor: YAMAMOTO KEIZO
IPC: B29C45/00
Filed: 1989-07-06
Abstract: PURPOSE:To form a favorable thin thickness with a free thickness and area without necessitating a specific countermeasure such as high-speed and high- pressure injection molding, by a method wherein an ejecting member is ejected into a cavity of a mold by leaving a gap behind between the tip part of the ejecting member and a counter mold surface in the cavity prior to curing of a molding material filled into the cavity. CONSTITUTION:A molding material 16 is cast into a cavity 14 of a mold 12. Simultaneously with filling of the molding material 16 into the cavity 14 or after the filling and prior to cure of the molding material 16 an ejecting member 18 is ejected within the cavity 14 of the mold 12 by leaving a gap behind be tween the tip part 19 of the ejecting member 18 and a counter mold surface 15 in the cavity 14. With this construction, a thin part 20 is formed between the tip part 19 and counter mold surface 15 in the cavity 14. In this instance, since the thin part 20 is formed while pushing away the molding material 16 by applying pressure to the molding material 16 by the ejecting member 18, it is not feared that defective molding such as defective filling is generated.

Title: Method for measuring grounding resistance of earth wire of pole
Inventor: WATANABE MAKOTO
IPC: G01R27/20
Filed: 1995-06-19
Abstract: PURPOSE: To measure the grounding resistance of earth wire in safety in a short time while reducing the labor by feeding signals for measuring a predetermined voltage to one and the other earth wires in parallel thereby eliminating the pole climbing work for disconnecting the earth wire. CONSTITUTION: A common earth wire 8 is stretched between poles 2a, 2b while being connected, at one end thereof, with the earth terminal 7 of a pole transformer and, at the other end thereof, with an earth wire 3b of the other pole 2b. When the grounding resistance is measured, measuring signals of predetermined voltage are fed, in parallel, to the earth wires 3a, 3b of one and the other poles 2a, 2b from a transmitter A. A receiver B measures the current value of measuring signal flowing through the earth wire 3a of pole 2a and then the grounding resistance of earth wire 3a is calculated, based on the current value and the predetermined voltage.  Consequently, when the grounding resistance is measured independently for the earth wire 3a of pole 2a mounting a commonly grounded transformer 6, it can be measured as it is even if the other earth wire 3b is connected with the earth terminal 7 of the transformer 6.

Filed: 1980-12-15
Abstract: PURPOSE: To eliminate occurrence of damage in a facing plate,by obliquely slicing the edged end part of a blade plate at its slide contacting side to the facing plate in a hydraulic machine and forming a chamfered part.  
     CONSTITUTION: Of upper and lower end edge portions of a blade plate 2 in each guide vane, a portion slide contacting to a facing plate 5 when the guide vane is swivelled in a closing direction, that is, the upstream side of a head part 22 and the downstream side of a tail part 23 in the blade plate 2 are obliquely sliced to form a chamfered part 24. In this way, the guide vane, at its transfer operation from an open state to a close state, allows the chamfered part 24 to be adapted to the side of the facing plate 5 and ride over. At this time, the facing plate 5 is pressed toward the direction of a guide vane bearing side 4. In consequence, occurrence of biting or rubbing of the end edge part of the blade plate to the facing plate 5 is eliminated to perform smoothly slide contacting operation of the blade plate to a seat rubber. When the guide vane is fully closed, an end face 21 of the blade plate 2 is closely attached to other portion than the chamfered part 24.
