Title: Controller of synchronous motor for servomotor
Inventor: SAKAMOTO KEIJI
IPC: H02P6/17
Filed: 1987-07-27
Abstract: PURPOSE:To prevent generation of an error rotating field by providing an angular position storage means, an angular position changing and operating means and an emergency stop means for reducing the input of a pulse width modulation type inverter to zero. CONSTITUTION:The controller of a synchronous motor M for a servomotor is composed of an angular position detection means encoder T, an angular position computing means A, a speed computing means V, a torque command operating means TC, a phase command operating means P, a three-phase current command operating means IC, a pulse width modulation type inverter PWM and others. In this case, there are provided an angular position storage means ME, an angular position changing and operating means AV, and an emergency stop means ES. Thus, when an inverter PWM is given an emergency stop command, it gives an OFF signal to all conducting elements to cut off the electric supply to the synchronous motor M to stop generation of a rotating field instantaneously. As a result, if the angular position detection means T should get out of order and the like, generation of a demagnetizing phase is prevented be forehand.

IPC: B29C70/06
Filed: 1984-09-04
Abstract: PURPOSE:To prevent the generation of wrinkles at the joint part between long base materials, by adhering and connecting the joint between said base material by a slit tape. CONSTITUTION:In a method for manufacturing a laminate board by laminating and molding laminates each of which is formed by stacking a required number of resin impregnated base materials, each of which is obtained by drying a long base material impregnated with resin varnish, and, if necessary, applying a metal foil to the upper surface and/or lower surface of the resulting laminated composite, the joint between each pair of the long base materials is adhered and connected by a slit tape. That is, the tape, to which slits each having a width of 1-10mm are formed at 1-100mm intervals, is used. If each interval is below 1mm, the tape becomes easy to cut and the joint is separated. If exceeds 100mm, non-adhesive parts increase and strain can not be absorbed. If the slit width is below 1mm, strain is hardly absorbed and, if exceeds 10mm, the adhesion and connection of the joint is imperfect and the joint is separated.

Title: Manufacture of clad band
Inventor: WATANABE TERUO
IPC: B23K20/04
Filed: 1981-11-19
Abstract: PURPOSE:To prevent lubricating oil from going into a press-contacting part, and to prevent bulging of a clad band, by dividing the cold rolling press-contact into 2 stages, rolling the first stage by low draft without using lubricating oil for rolling, and rolling the second stage by high draft by using lubricating oil. CONSTITUTION:As for draft of rolling press-contact, which uses no lubricating oil for rolling, of the first stage, rolling is executed by selecting usually 8%- maximum 25%, usually up to 15% draft in order to avoid the fact that lubricating oil permeates the junction surrace in the second stage. Subsequently, since rolling press-contact of the second stage uses lubricating oil, high draft is adopted, that of >=10% or >= maximum 30% is selected, and rolling is executed. Subsequently, an aluminum stripe clad band is junctioned completely and its thickness is set to a desired value, by executing the diffusion annealing treatment and finishing cold rolling.

IPC: G05D3/00
Filed: 1989-07-20
Abstract: PURPOSE:To simplify a whole structure and to facilitate manufacturing by using a rigid link connecting the first and second rigid bodies by an elastic hinge as a deforming member. CONSTITUTION:When voltage is applied to a piezoelectric actuator 7, the force in an X-axis direction acts on a rigid body 17 and a rigid body 18a is pushed in the X-axis direction. By This mechanism, the rigid body 18a revolves around an elastic hinge 18b and a moving rigid body 2 is displaced by displacement quantity (u) in the X-axis direction through an elastic hinge 18d. This displacement quantity (u) becomes b/a times of the displacement quantity us of the piezoelectric actuator 7 and displacement is magnified. In this case, the displacement of elastic hinges 18c, 18d coincides with the normal line direction of rotary motion centering around the elastic hinge 18b and, as a result, displacement can be efficiently magnified without generating wastefulness in transmitted displacement. Therefore, a whole structure is simplified and manufacturing becomes easy.
