A number of LEDs 6 are vertically and horizontally arrayed on a printed circuit board 5, thereby forming a display surface. Switches 7 for turning on or off the LEDs 6 and keeping them in an on or off state are provided at locations corresponding to or close to the LEDs 6. With this construction, the LEDs 6 can be turned on or off directly from the display surface.

A biaxially blow-molded bottle-shaped container (1) of synthetic resin includes a generally square cross-sectional body portion (2). A panel wall (3) for absorbing a reduced pressure generated in the bottle-shaped container is provided on a flat wall portion at each side of the body portion. Depressed cross grooves (5) are provided spaced apart in parallel in a ridge line portion between the adjacent panel walls (3, 3). The body portion may be cut-off at corners thereof to provide vertically elongated flat surfaces (4), and depressed cross grooves (5) may be provided spaced apart in parallel in each flat surface (4).

摘要:
A pressure resistant bottle-shaped container having a body including panels surrounded by outer sheaths, characterized in that each panel has stress absorbing strips comprising vertexes recessed from the outer surface of the panel toward the interior of the container and bending lines formed in V shape and inverted V shape from the vertexes toward the outer sheaths. Thus, the container does not retain permanent deformation by the deformations resulting from pressure changes at the time of filling high temperature liquid content.

A yellow dye-donor element for thermal dye transfer and having good characteristics for ink formation, and a thermal transfer sheet made using the yellow dye-element, having adequate sublimatability or vaporizability, good coloring, with a high printing density on receiving papers, and high storage stability and light stability of printing image, and employable as a yellow color among the three primary colors are provided. The above yellow color-element comprises a yellow dye dispersed or dissolved in a polymeric binder, which is represented by the formula (I): ##STR1## wherein R.sub.1 is an alkyl group of C.sub.1 -C.sub.12, an allyl group or a crotyl group; X is hydrogen, halogen or a C.sub.1 -C.sub.4 lower alkyl or C.sub.1 -C.sub.4 lower alkoxy group; Y is a C.sub.1 -C.sub.12 alkyl, C.sub.5 -C.sub.7 cycloalkyl, C.sub.1 -C.sub.4 alkoxy, phenyl, tolyl, or phenoxy group; and A is --CH.sub.2 CH.sub.2 --, --CH.sub.2 CH.sub.2 O--, or --CH.sub.2 CH.sub.2 CH.sub.2 --.
摘要:
A process for producing stable (.beta.-type) dioxazine violet pigment having superior gloss and tinting strength to the metastable (.alpha.-type or a type analogous thereto) dioxazine violet pigment, by mixing an aqueous suspension of a metastable dioxazine violet pigment with an acetate or ketone compound and then heating the mixture. The metastable dioxazine violet pigment may be that obtained according to the conventional method, and employable in situ.
摘要:
Bottles made of saturated polyester resin, particularly polyethylene terephthalate resin, by orientation blow molding exhibit phenomenal properties and characteristics, but suffer from a serious disadvantage in that the bottle neck is greatly inferior in the properties and characteristics to the bottle body, because the neck is molded into the final form without undergoing biaxial orientation. Biaxial orientation gives the bottle body outstanding properties and performance because it causes the molecules of a molding resin material to be arranged in the same direction. Based on this principle, the bottle neck is given the same effect as is produced with biaxial orientation by applying tensile force in a certain direction to the molecules of a molding resin material while it is still in a temperature range at which orientation takes place.

Disclosed is a magnetic recording and reproducing apparatus of the rotating head type in which a magnetic tape is drawn out from a tape cassette by means of tape lead-out pins and brought into close contact with a head cylinder containing rotating heads. Each of the tape lead-out pins is mounted on a slide member which is adapted to be driven by a drive means and slideably guided along a guide path consisting of a guide slot formed in a base plate of the apparatus. With such arrangement, the guide path need not coincide with the path of the driving means, whereby the tape loading mechanism and hence the apparatus as a whole can be small in size.
