Title: Flatness straightening method of press formed parts
Inventor: TAKADA MIKIRO
IPC: B21D37/08
Filed: 1998-03-30
Abstract: PROBLEM TO BE SOLVED: To easily and inexpensively straighten the flatness of press formed parts. SOLUTION: In this method, the flatness of a flat surface part 1a is straightened by forming plural triangular beads (recessed beads) 2 along the end edge of a flange part 1b of a bottom plate (press formed parts) 1 having the flange part 1b which is bent at a nearly right angle in at least one part of the peripheral edge of a flat surface part 1a. Although a projected downward bending is generated in the flange part 1b when the projected downward camber is generated in a flat surface part 1a of the bottom plate 1, the camber of the flat surface part 1 is straightened by contracting (squeezing) the line length of the lower end edge of the flange part 1b which extends with respect to an upper end edge with the triangular beads 2.  Thus, straightening work using a re-striking die is unnecessitated, the flatness required for the bottom plate 1 is easily and inexpensively secured by working only the flange part 1b with a simple device.

Title: Lever operating device for damp car
Inventor: TORIEDA KAZUYUKI
IPC: B60P1/04
Filed: 1979-06-29
Abstract: PURPOSE: To improve safety by interlocking a forward-backward pivoting regulating member with operating levers for hinge and lifting and lowering load boxes to restrain the operation of the operating lever for lifting and lowering the rear body when the operating lever for the hinge is imperfectly operated.  
     CONSTITUTION: When a rear body is damped in a desired direction, operating levers 15, 15' for hinge are first suitably operated forward and backward to engage and disengage a desired hinge portion. Next, an operating lever 17 for lifting and lowering rear body is changed over to the upper position. When the levers 15, 15' are then not changed over to a proper position, but to the position shown by the solid line in the drawing, an engaging pin 31 engages the ends of stoppers 22, 22' while the end of an engaging arm 32 is located in front of them. When the lever 17 is then operated to the upper position, it engages an engaging arm 32 to stop its movement. On the other hand, when both levers 15, 15' are properly operated, the engaging pin 31 and arm 32 can pivot to the position shown by the chain line to permit the operation of the lever 17.

Title: Sequence instruction processing circuit for programmable controller
Inventor: ASAI TOSHIMITSU
IPC: G05B19/05
Filed: 1991-04-16
Abstract: PURPOSE:To shorten the processing time of the whole of a sequence program by discriminating whether a sequence instruction should be executed or not in accordance with the kind of the sequence instruction and the operation result obtained in steps preceding this sequence instruction. CONSTITUTION:A CPU 1 takes in information of a memory A2 and stores it in a memory D3. When a discriminating circuit 7 decodes a command from the CPU 1 by an instruction decoding circuit 8 to discriminate that the next instruction is AND operation, it is discriminated whether information in the memory D3 is '0' or '1'. When it is '0', the discriminating circuit 7 transmits the completion of the instruction to the CPU 1 without taking in information of a memory B4. Then, the CPU 1 transfers contents of the memory D3 to a memory C5 and finally executes the END instruction to discriminate the completion of all of one processing, and the control is returned to the start of the program again to repeat the same processing.

Title: Filter circuit
Inventor: KANARI SHIGEAKI
IPC: H03H11/12
Filed: 1984-04-27
Abstract: PURPOSE:To obtain a desired LPF characteristic by making a DC voltage at an output terminal of an amplifier constant and changing an applied voltage to the 1st and 2nd variable capacitors connected between a time constant circuit and an amplifier and between the time constant circuit and a voltage source so as to change the capacitance value thereby absorbing the variance of time constant. CONSTITUTION:DC potentials Ve, Vf at points, e, f are expressed by Equation I, where VBE is a base-emitter potential difference of a transistor. In changing a variable voltage source V6 by DELTAV6, the Ve, Vf are expressed in Equation II and even when the variable voltage source V6 is changed, since the relation of Ve= Vf exists, a DC potential Vg of an output terminal 10 of the amplifier is made always constant. Thus, potential differences Vc2, Vc4 across variable capacitors C2, C4 are expressed by Equation III and when the V6 changes by DELTAV6, the relation is expressed by equation IV and the potential difference across the variable capacitors C1, C2 changes identically by adjusting only the variable voltage source V6 connected to an adjusting terminal 14. Thus, the capacitance value of the variable capacitors C1, C2 is changed identically.

Abstract: PURPOSE:To decrease an amount of water used to a minimum value, by a method wherein a spread pipe, through which sand can be spread right therebelow, and a jump pipe, through which sand can be spread in a horizontal direction from a ship hull, are provided, and this enables sand to be spread even if the depth of water is low. CONSTITUTION:In a sand spreading ship which is used in water carriage practice, by which a soft ground is covered with soil, a spread pipe 2, through which sand can be spread right therebelow, and a jump pipe 4, through which sand can be spread in a horizontal direction from a ship hull, are provided. A valve 5 and discharge ports 6 and 8 are situated to each of pipes 2 and 4 an energy-reducing surrounding is attached to a discharge port 6 of the spread pipe 2, and this enables sand to be spread within a range limited to a specified area without diffusing sand in water. The utilization of the jump pipe 4 permits sand to be effectively spread in even the corner part of an embarkment where the depth of water is too low to allow enterance of a ship. This, in either case, enables an amount of water used to be decreased to a minimum value necessary to a construction work.
