Title: Construction work for sand pile
Inventor: MISAKA KAZUMA
IPC: E02D3/08
Filed: 1981-06-05
Abstract: PURPOSE:To easily and quickly construct an expanded diameter sand pile by a method in which while penetrating a hollow pipe into soft ground by giving a vibration to the pipe, a wetted sand is supplied into the pile to form a wetted sand layer, and then the hollow pipe is drawn out. CONSTITUTION:While penetrating a hollow pipe 1 into soft ground 2 by a vibro pile driver 6, a wetted sand 3 of a nearly saturated water content is supplied into the pile 1 (Fig. a), whereupon the wetted sand is fluidized by vibration. In this case, as the pipe 1 penetrates, the wetted sand 3 is supplied into the pipe 1 by controlling the pressure of the wetted sand 3 at the lower end of the pipe 1 in such a way as to make it greater than the passive earth pressure of the soft ground 2, and thereby the wetted sand 3 is continuously discharged into the soft ground from the lower end of the pipe 1 to form a wetted sand layer 4 (Fig. d). When the pile 1 is drawn out while operating the pile driver 6, the wetted sand 3 is left behind below the pile 1 and a sand pile 5 having a larger diameter than that of the pile 1 is formed integrally with the wetted sand layer 4.

IPC: H01F38/28
Filed: 1978-07-15
Abstract: PURPOSE: To simplify the assemble by attaching the secondary winding or a coil frame with the winding wound around it to I-shaped magnetic substance.  
     CONSTITUTION: Four projection pieces 3 are mounted on a magnetic substance 1, two central projection pieces have a double cross section greater than that of the end projection piece and a spacing 3 is formed in assembling the magnetic substance by two magnetic substances 1 and 2. A through-bar used as a primary winding 5 for each phase is passed through the spacings respectively. A secondary winding is wound around the magnetic substance 2 corresponding to the primary winding. In the absence of the phase at the end, the secondary current induced in the lacked phase may be equivalent to one percent of the current flowing through the conductive phase, therefore no influence would be appeared. The secondary current induced by influence of the gap can be selected by interposing the insulated member between the coupling portion of the magnetic substance when it is assembled. According to such the construction, the yoke is integrated with other parts to be formed in a small size and light weight and a wide variety of the machine types having various characteristics can be easily materialized.

Filed: 1986-04-15
Abstract: PURPOSE:To decrease the number of mask patterns by providing the number of stages of logical gates as a predetermined wiring layer number between a memory cell storing data and an output terminal outputting the data. CONSTITUTION:When a 4-bit data to be outputted is all at a power voltage level, both switches S1, S2 are turned to the position A through the wiring layer decided in the stage of forming to connect a NOT circuit 10. As a result, memory cells Q1, Q2, Q3, Q4, a data line 5 and a contact window pattern 6 are not required. When the data to be outputted are all at ground level, the switches S1, S2 are turned to the position B and since the NOT circuit 10 is not connected, no contact window pattern 6 is required. Thus, the mask pattern number is decreased depending on the number of data outputted at a power voltage level or ground level.
