摘要： PROBLEM TO BE SOLVED: To reduce variations at manufacture, equalize resistance variation characteristics and improve the precision by varying the resistance by deforming a conductive contact, in such a way that its contact area with a first resistor pattern changes through the pressing operation of a support member. SOLUTION: When the upper portion of a support part 10a opposed to a first resistor pattern 4 is depressed, leg parts 10b are elastically deformed and a curved surface 11a of a conductive contact 11 comes into contact with the center part of the first resistor pattern 4. When the support part 10a continues being pressed, the curved surface 11a is deformed and its contact area with the first resistor pattern 4 gradually increases, the resistance at both ends of the first resistor pattern 4 is reduced, so as to provide the first resistor pattern 4 with functions of a variable resistor. When the support part 10a stops being pressed, it is put back in its original state by the self elasticity of the leg parts 10b, and the contact area of the curved surface 11a with the first resistor pattern 4 is reduced gradually to its original state while varying the resistance.

摘要： PROBLEM TO BE SOLVED: To provide a small and inexpensive input device made of few materials and with good productivity. SOLUTION: In the input device, the other face side of a flexible board 6 is bonded to the lower face of a board member 3 and a terminal part 8b installed on one face side of the flexible board 6 is soldered to the land part of the printed board 1. Thus, only the bonding of the flexible board 6 to the board member 3 and the soldering of the terminal part 8b to the land part 1b are required in assembly. Thus, the inexpensive input device with fewer assembly man-hours than a conventional case and with good productivity can be supplied.

摘要： PROBLEM TO BE SOLVED: To provide a compact and highly productive and inexpensive input device capable of realizing face mounting. SOLUTION: In this input device, plural terminals 9 made of metallic materials are embedded in a substrate part 3 of an operating member S so as to be connected to distortion detecting elements 7a and 7c so that this input device can be face mounted on a printed circuit board 1 by those terminals 9. Thus, this input device can be made inexpensive by making it unnecessary to use any conventional flexible substrate, and also made compact by making it unnecessary to use any flexible substrate larger than the substrate part 3.

摘要： PROBLEM TO BE SOLVED: To improve controllability by permitting the center of a resistor body pattern to protrude to the side of a conductive contact point, permitting the conductive contact point to be deformed so as to vary its contacting area with respect to a resistor body pattern through the pressing control of a support member, and allowing resistance value to be variable. SOLUTION: In a variable resistor, when the upper portion of a support 6a which faces a resistor body pattern 5 is pressed, a leg 6b is imparted with elastic deformation, and further a curved surface 7a of a conductive contact point 7 comes into contact with the protruded center of the resistor body pattern 5. When the support 6a is kept pressed, the curved surface 7a comes into contact with the conically protruded resistor body pattern 5, while being deformed to gradually increase the contacting area and vary the resistance value at both ends of the resistor body pattern 5, thereby being imparted with a function as a variable resistor. When the support 6a is released from being pressed, the support 6a is restored to the original state by the elasticity of the leg 6b itself, and further, the contacting area of the curved surface 7a with respect to the resistor body pattern 5 is reduced while varying the resistance value to restore the original state.

摘要： PURPOSE:To improve a gage factor by a method wherein at least one out of graphite and a metal powder is diffused, as a main conductive material, to a thermosetting resin so as to form a resistance ink. CONSTITUTION:When graphite or a metal powder is used as a main conductive component, a gage factor is lowered when the mixture amount of the metal powder is too much, but a resistance becomes too high and unstable when the mixture amount is small. As a result, e.g. in the case of graphite and a pehnolic-resin binder, the content of graphite is set at 8 to 25vol.%. In addition, since the metal powder alone is stable and a high resistance is hard to obtain, graphite is mixed. In addition, when a thermoplastic resin is used as a binder, its hysteresis is large and it is unsuitable for a sensor. As a result, a thermosetting resin is used. An ink which is composed in this manner is printed on an insulation-treated phosphor bronze plate, it is heated and hardened, and a resistor is formed. Thereby, it is possible to obtain the printed resistor which is suitable for a strain gage.

摘要： PROBLEM TO BE SOLVED: To provide a highly reliable load sensor wherein a fastening force for mounting a fixed end part does not adversely affect the characteristics of strain detection elements and product-by-product variations in performance are reduced. SOLUTION: This load sensor is designed so that part of an opening 3 stands among the strain detection elements 7 and 8 mounted on straining parts 4 and the center 'A' of a shaft hole 2a in an attachment part 2 on the fixed end side. This prevents the elements 7 and 8 from being directly affected by a deformation owing to a strong fastening force that presses peripheral parts of the shaft hole 2a, thus preventing the characteristics of the elements 7 and 8 from varying on a product-by-product basis. A projection 6b projecting in the wall thickness direction is provided on an end part of a pressure receiving part 6 and a top part of this projection part 6b is used as a load point 6a. Even if the relative distance between an object of measurement and the load sensor varies to some extent, the load of the object of measurement can be surely exerted on the load point 6a. Accordingly, malfunction can be avoided even if there is some error in the attaching position of the load sensor.
