摘要:
In a production process of a poly(arylene sulfide), a mixture containing an organic amide solvent, an alkali metal hydrosulfide and an alkali metal hydroxide in a proportion of 0.95 to 1.05 mol per mol of the alkali metal hydrosulfide is heated and dehydrated in a dehydration step. After the dehydration step, as needed, an alkali metal hydroxide and water are added to control the total number of moles of the alkali metal hydroxide, and the number of moles of water so as to amount to 1.00 to 1.09 per mol of a sulfur source including the alkali metal hydrosulfide existing in the system and to 0.5 to 2.0 per mol of the charged sulfur source, respectively. A polymerization step is conducted by a two-stage process.

Novel full-length cDNAs are provided. 1970 cDNA derived from human have been isolated. The full-length nucleotide sequences of the cDNA and amino acid sequences encoded by the nucleotide sequences have been determined. Because the cDNA of the present invention are full-length and contain the translation start site, they provide information useful for analyzing the functions of the polypeptide.

Reverse bias voltage VM is applied to any one of self light emitting elements arranged on a light emitting panel 1 under detection mode. Current corresponding to weak current flowing to the element is supplied to a transistor Q3 by the operation of a current mirror circuit comprised of transistors Q1, Q2. The current mirror circuit is formed with the transistor Q3 as a control side current source transistor and transistors Q4 to Q7 as a controlled side current source transistor. The sizes of the controlled side current source transistors Q4 to Q7 are set to, for example, 1:2:4:8 with respect to the control side current source transistor Q3 so as to construct current amplifying means. Current value amplified by a current comparison type comparator 7 is compared with current value from a reference current source 8 and its output is latched by a latch circuit 9 and stored in a data register 10. If a weak current over a predetermined value flows when reverse bias voltage is applied to the self light emitting element, it is determined that a possibility that the self light emitting element turns into a light emission fault is high and notifying means is driven appropriately using data stored in the data register 10.

At least one layer of an aliphatic polyester resin, which is biodegradable and is also excellent in gas-barrier property and mechanical strength, is laminated with another thermoplastic resin layer to provide a satisfactory multilayer stretched product. The aliphatic co-polyester (A) has a crystallization temperature Tc1 due to crystallization in the course of heating, which is higher than the glass transition temperature Tg of another thermoplastic resin.

In a detection mode, a reverse bias voltage VM is applied to any one of scan lines K1-Km arranged in a light emitting display panel 1. The electrical potentials generated at respective data lines A1-An of this time are supplied to potential determination means J1-Jn. In the potential determination means J1-Jn, the electrical potentials generated at the respective data lines A1-An are supplied to switching elements Q31-Q3n via transfer switches Q11-Q1n. When the electrical potentials are the threshold voltages of the switching elements Q31-Q3n or greater, the outputs of comparators CP1-CPn are inverted, and the states of this time are latched in latch circuits LC1-LCn to be stored in a data register 11. By data stored in the data register 11, it is determined whether or not a defect has occurred in pixels of the display panel, and the location thereof is also determined.

the present invention aims to achieve that geomagnetism can be sensed in high precision while eliminating an adverse influence by magnetic noise with respect to a geomagnetic sensor provided in a housing, and correct azimuth information can be acquired. A portable terminal apparatus according to the present invention is arranged by that both a first housing (11) and a second housing (12) are coupled to each other by way of a hinge portion (13) under pivotable condition, a geomagnetic sensor (33) is provided on a circuit board (32) in the second housing (12), and also, a speaker (19) is provided on the side of a rear surface thereof. Both this geomagnetic sensor (33) and a speaker (19) corresponding to a component for generating magnetic noise which gives an adverse influence with respect to the geomagnetic sensor (33) are provided in the vicinity of each other within the same second housing (12), and both the members are arranged on the same plane. In this structure, since a magnetic force line (35) which is caused by magnetic noise generated from a magnet (19a) of the speaker (19) is intersected with respect to the geomagnetic sensor (33) at a right angle, and thus, a horizontal direction component thereof is not produced, the geomagnetic sensor (33) can correctly sense the geomagnetism without being adversely influenced by the magnetic noise.
