Title: Phase control method for halogen heater
Inventor: NAKADA YASUHIRO
IPC: G05D23/24
Filed: 1991-02-21
Abstract: PURPOSE:To reduce the occurring frequency of a rush current and to improve the reliability of the phase control of a halogen heater by performing the forcible full firing for a half period of a commercial power supply when the halogen heater generates heat after having its working stop state for a fixed time. CONSTITUTION:A controller 5 counts the time during the working stop state of a halogen heater 1 and decides that the heater 1 is kept in a preheating state and no rush current flows as long as the counted stop time of the heater 1 is shorter than a prescribed period of time. Thus the controller 5 secures the conduction of a triac 2 at an energizing angle subject to a temperature detector 6 in order to turn on the heater 1. If the counted stop time of the heater 1 is longer than the prescribed time, the full firing is applied to the heater 1 in the first half period and the heater 1 is controlled according to the controller 6 after the heater 1 is preheated. Thus the rush current flows just once and therefore the phase control is applied to the heater 1 with high reliability.

IPC: B32B15/08
Filed: 1989-02-06
Abstract: PURPOSE:To make variable vibration damping material perform the vibration damping action having the desired damping factor in response to usage and consequently widen the usage of the variable vibration damping material by a method wherein electroconductive metal layers, as the intermediate layer of which sheet-like piezoelectric polymer material is interposed therebetween, are made into an integral body and external resistor for converting electrical output is connected between the metal layers. CONSTITUTION:When external vibration is applied to variable vibration damping material 11, inner piezoelectric polymer material 13 deforms and develops strain. As a result, electric charge is induced in metal layers 12 on both sides of the variable vibration damping material and then led to external resistor 14 so as to be converted to the required heat energy in order to discharge a part of mechanical energy outside for disposal. By changing the value of the resistance of the external resistor 14, the discharge of heat energy is controlled so as to let the variable vibration damping material 11 perform the vibration damping action having the desired damping factor in response to usage.

Abstract: PURPOSE:To improve corrosion resistance by providing an alloy composition in which specific amounts of Cr and P are incorporated to Ni to an Ni-base alloy powder for forming amorphous sprayed deposit. CONSTITUTION:This Ni-base alloy powder has a composition consisting of, by atom, 10-30% Cr, 12-25% P, and the balance Ni and containing, if necessary, 1-8% B and/or Si. This powder can be prepared by forming the molten alloy with the above composition into powder by a high-pressure water atomizing method and then subjecting this powder to drying and grading. When this powder is used as thermal spraying powder, an amorphous sprayed deposit excellent in corrosion resistance can be obtained. In the above composition, when Cr content is less than 10%, the desired superior corrosion resistance cannot be obtained and, when it exceeds 30%, the melting temp. of the powder is raised and many defects, such as bores, take place in the sprayed deposit, and further, making amorphous is inhibited and corrosion resistance is deteriorated. When P content is beyond the above range, making amorphous is inhibited. When B and Si contents are less than 1%, the desired improvement in the effect of making amorphous cannot be obtained and, when they exceed 8%, the action of making amorphous is deteriorated.
