摘要:
The present invention provides a resol-type phenol resin composition which can be cured even in a low temperature range, using a curing accelerator which has no adverse effect on other materials or substances with which the resulting cured article is in contact, or a curing accelerator which requires a small amount of an additive. The composition comprises a resol-type phenol resin (A), an alkali earth metal oxide and/or an alkali earth metal hydroxide (B) (e.g. magnesium oxide, calcium hydroxide, barium hydroxide, etc.), and a salt (C) of a sulfur atom-containing oxo acid and a nitrogen atom-containing base (e.g. ammonium thiosulfate, etc.). This composition is cured at 10 to 110° C.

摘要:
A driving system for an induction motor which is capable of properly controlling the speed of an induction motor over its high-speed revolution range and also features an excellent responsiveness to a speed command. In this system, a slip pulse (SSP) and a phase shifting pulse (FSP) are calculated by a slip pulse generator circuit (20) and a phase shifting pulse generator circuit (21) in accordance with slip pulse data (SB) and phase shifting pulse data (FB) which are calculated by a processor (1) in accordance with the speed command and an output of a speed detector. A counter (24) issues the first changeover signal (CS1) each time it receives a specified number of pulses from a pulse overlapping circuit (23). The first changeover signal corresponds to a feedback pulse calculated in accordance with the output of the speed detector and also to the slip pulse and the phase shifting pulse added. A square wave output circuit (26) generates square wave signals (Us through Ws) in accordance with the first changeover signal, the second changeover signal (CS2), which is obtained by delaying the first changeover signal, and rotational direction identifying signals (RS, RS) received from the pulse overlapping circuit. While the motor is running at high speed, the drive of the motor is controlled in accordance with the square wave signals; while it is running at low speed, PWM signals (Up through Wp) generated by the processor are used in place of the square wave signals.

An ion exchange membrane reinforced by a woven reinforcing fabric is provided in which the difference between the thickness of the membrane at the crossover points where the warp and weft strands of the fabric cross each other and that at the window portions defined by the crossed warp and weft strands is not greater than 35 .mu.m. This membrane may be produced for example, by heating an assembly comprising at least two fluorinated polymer films each having pendant sulfonyl groups and/or carboxyl groups in a melt-fabricable form, and a woven reinforcing fabric sandwiched between the polymer films, and a support sheet laminated to the outermost polymer film, while applying a negative pressure to one side of the assembly that is remote from the support film, followed by converting the sulfonyl and/or carboxyl groups of the polymer films to sulfonate and/or carboxylate groups. This reinforced ion exchange membrane has flat film surfaces, thereby eliminating the danger of gas bubbles during chloralkali electrolysis which enables the cell voltage to be low, so that electric power consumption can be reduced.
