Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To save labor and time in the continuous bending of an object, for example, an S-shaped object having different directions in bending, and to prevent reduced thickness in the outer bent part of the object. SOLUTION: A three-dimensional moving mechanism is introduced to the movement of a press bending roller 24 of a bender mechanism 5 in a high frequency heating bender of a press bending method; in bending an object to be bent, i.e., a pipe 1, to the right and then to the left, the press bending roller 24 is moved to the opposite side across the pipe 1, applying a pressurizing force to the side face, and thereby eliminating the 180 degree turn of the pipe 1 in bending it in an S-shape.  In addition, the rotation of the press bending roller 24 is stopped by pressing a brake shoe against it, imparting a compression force to the pipe 1 extruded to the bender mechanism 5 side by a pusher unit 3, increasing thickness once at the part of the pipe 1 near the high frequency heating coil 10 before bending the pipe by the press bending roller 24, and thereby obtaining the effect of suppressing reduction in the thickness.

Title: Voltage controlled oscillator
Inventor: KUBO KUICHI
IPC: H03B5/32
Filed: 1998-11-06
Abstract: PROBLEM TO BE SOLVED: To improve the linearity of the voltage controlled oscillator by applying a control voltage between a terminal of a voltage variable capacitive element and a terminal of a constant voltage source and by decreasing a voltage across the voltage variable capacitive element more than the control voltage to obtain a large capacitance change in the voltage variable capacitive element. SOLUTION: The level of the anode of the voltage variable capacitive diode 4 is increased through the provision of the constant voltage source E and a control voltage VX is applied to a point between the voltage variable capacitive diode 4 and the constant voltage source E. Then the control voltage VX can be cancelled by the constant voltage E and a voltage VY across the voltage variable capacitive diode 4 is smaller than the control voltage VX (VY=VX-E). Thus, the capacitance characteristic of the voltage variable capacitive diode 4 with respect to the control voltage VX shows a curve resulting from shifting the substantial characteristic toward a higher voltage by the constant voltage E.  According to the method of this voltage application, a reference voltage for a compensation voltage to set an oscillated frequency at room temperature can be set to a voltage where the linearity in the voltage capacitance characteristic of the voltage variable capacitive diode 4 is high, resulting that a large capacitance change with respect to the input control voltage can be obtained.

Title: Lithium secondary battery
Inventor: MORITA TERUYOSHI
IPC: H01M10/0566
Filed: 1991-12-16
Abstract: PURPOSE:To provide a lithium secondary battery having an excellent charge/ discharge cycle characteristic and over discharge characteristic by using a lithium-including oxide for a positive electrode and a niobium pentoxide for a negative electrode. CONSTITUTION:In a niobium pentoxide, because of entrance and exit of lithium to/from a crystal lattice thereof, physical expansion and contraction are hardly caused and therefore breakage of a negative electrode 3 due to a battery cycle is not generated, thus an excellent cycle characteristic is exhibited. Since a diffusion speed of lithium into a niobium pentoxide is large, rapid charging is possible. Since the niobium pentoxide is electrochemically stable even at a high potential as high as 4 volts, it can retain stability at an over discharge state and therefore exhibit an excellent battery characteristic even after over discharge.
