A line resin tube includes a resin composition (C) including 60 to 230 parts by mass of polyamide resin (B) based on 100 parts by mass of polyamide resin (A), wherein the polyamide resin (B) includes 6-nylon and/or denatured 6-nylon, and has a bending modulus of elasticity of 1 GPa or less measured by ASTM D790; and the polyamide resin (A) is obtained by polymerization condensation of xylylene diamine and adipic acid, and has a relative viscosity from 2.0 to 6.0 measured at 25° C. in a solution of 98% concentrated sulfuric acid.
摘要:
A tuning fork type piezoelectric resonator element having a wide operating temperature range and method of manufacture comprising a base having two sides and opposite ends,a plurality of resonating arms 18 protruding from one end of the base 12, a plurality of mount electrodes 16 corresponding in number to said resonating arms disposed at an opposite end of the base 12 and being connected by lead terminals to the mount electrodes using a conductive joining material. The mount electrodes 16 are spaced a minimum distance apart sufficient to prevent shorting caused by diffusion of the conductive joining material 22 for joining lead terminals 32 to the mount electrodes 16 with the lead terminals connected to said mount electrodes without forming a bend in the lead terminals at the end thereof adjacent the mount electrodes and with the width of the base along each side thereof set to a value that permits the lead terminals to be linearly joined to the mount electrodes.
摘要:
A piezoelectric resonator element is provided including a base portion and a plurality of resonating arms extending from the base portion. A notch part is formed in the base portion. Grooves are formed in the front and back surfaces of the resonating arms. A driving electrode is provided at least in the grooves of the resonating arms. The driving electrode has a lower layer and an electrode layer formed on the lower layer. The thickness t of the lower layer is in the range 0.07
摘要:
A portable electronic apparatus includes a printer portion provided in a main body and having a printing head, a recording paper holder provided in a portion of the main body near to the printer portion, a holder cover openably attached to the paper holder, a platen provided on the holder cover and facing the printing head when the holder cover covers the paper holder, and a paper sensor provided on the holder cover, located near to the platen, and detecting the recording paper. The apparatus may includes a water-drop proof cover removably attached on the main body, covering a portion of the outer surface region of the main body which faces the printed recording paper discharged out from a recording paper discharge port formed in the portion of the outer surface region, and housing the printed recording paper discharged out from the paper discharge port.
