Abstract:
Disclosed is a thermoplastic resin foamed sheet wherein pillar-shaped resin portions observed in a cross section in the thickness direction of the sheet satisfy requirement (1): the number density of pillar-shaped resin portions intersecting the thickness centerline of the foamed sheet is from 1 to 20 pillars/mm-centerline and requirement(2): the average thickness of pillar-shaped resin portions intersecting the thickness centerline of the foamed sheet is from 10 to 500 μm.
Abstract:
Disclosed are methods for producing a thermoplastic resin article composed of a foamed thermoplastic resin sheet shaped in a predetermined shape and a functional member of thermoplastic resin which stands locally on and is fused with the foamed sheet. In the methods, a mold having a molding surface with a recess for forming a functional member therein is used in combination with a counter mold. A foamed thermoplastic resin sheet is stuck on the molding surface by suction or supply of compressed air so that the recess is sealed with the foamed sheet. Then, molten thermoplastic resin is fed into the recess. Thus, the molten thermoplastic resin is fused with the foamed sheet to form a thermoplastic resin article.

Abstract:
Disclosed are methods for producing thermoplastic resin foamed articles having a high expansion ratio and a large thickness by vacuum forming using a pair of molds through which vacuum sucking can be conducted and holding means for holding a thermoplastic resin foamed sheet at a predetermined position between the molds or a molding apparatus comprising a first mold having a molding surface through which vacuum sucking can be conducted, a second mold having a molding surface provided with sheet fixing means on at least the peripheral portion of the molding surface, and holding means for holding a thermoplastic resin foamed sheet at a predetermined position between the molds. In the methods, a heated and softened foamed sheet is supplied between the molds and vacuum sucking is started when the molds have been closed appropriately. Thus, the foamed sheet is vacuum formed to afford a molded article.

Abstract:
A content viewing/listening device for viewing and listening to contents has a content information obtaining section that obtains content information, and a content information display control section that performs control to display a content list on a content display section with respect to each of content categories based on the content information obtained in the content information obtaining section. When receiving an instruction to display the content list, the content information display control section produces, on a content presently being viewed and listened to, a presently-viewed/listened-to-content display in such a form as to be visually recognizable and to indicate that the content is presently being viewed and listened to, and displays the content list so that the content list is divided into portions on a plurality of pages if the content list cannot be displayed on one page.
Abstract:
The television (1) includes: an infrared radiation receiver (119) which receives from a user an instruction to select a program cell; and a CPU (118) which generates a user interface screen of an electronic program table to be displayed on an LCD (110). The CPU (118) generates the user interface screen of the electronic program table such that a time zone item column located in a left direction of a selected program cell and a time zone item column located in a right direction of the selected program cell are indicated with deep blue, and other time zone item columns are indicated with light blue.
Abstract:
A method is disclosed for making a multi-layer up molded article. One embodiment of the invention involves (a) step of, by a shut-off pin slidably received in a resin-supplying gate open to a cavity face of a first mold, bringing the resin-supplying gate into an opening state, and supplying, by way of the resin-supplying gate, a molten thermoplastic resin between the cavity face of the first mold and a cavity face of a second mold which are in an open state; (b) step of bringing the resin-supplying gate into a closing state the shut-off pin and projecting a part of find shut-off pin from the cavity face of the first mold; (c) step of closing find first and second molds so as to attain a closed state, thereby shaping find resin, and cooling thus shaped resin so as to be solidified; (d) step of opening find first and second molds so as to be placed in the open state; (e) step of returning find shut-off pin into find first mold, thereby forming a hold in the resin solidified in find step (c) and bringing find resin-supplying gate into the opening state, and supplying a molten thermoplastic resin between the resin solidified in find step (c) and the cavity face of find second mold by way of find resin-supplying gate and find hole; (f) step of bringing find resin-supplying gate into the closing state by means of find shut-off pin; (g) closing find first and second molds so as to attain the closed state, thereby shaping find resin, and cooling thus shaped resin so as to be solidified; and (h) opening find first and second molds so as to remove it therefrom.
Abstract:
In a doppler type ultrasonic flow meter 1 for measuring the volumetric flow of a measurement object fluid 10 using doppler shift of ultrasound, 1 pair of ultrasonic transducers 3a, 3b perform transmission of ultrasound and reception of an ultrasound echo resulting from the ultrasound being reflected. The 1 pair of ultrasonic transducers 3a, 3b are disposed on an extension line of a measurement line ML for performing measurement of doppler shift, symmetrical about the center axis 5 of a pipe 2 with a measurement object fluid 10 flowing through its inside, and on the outside of the pipe 2. A flow profile for the side opposite, with respect to the center axis 5 of the pipe 2, the side on which the respective ultrasonic transducer 3a, 3b is disposed is used for the calculation of the volumetric flow of the measurement object fluid 10.
Abstract:
On a folding section of the thermoplastic sheet there is provided one or more thin-walled section, extending in a longitudinal direction of the folding section, whose minimum thickness is not less than 1/10 and not more than ⅔ the thickness of the thermoplastic resin sheet. Thus, it is possible to provide a box in which rebound of the folding section is reduced and an operation efficiency upon setting up the box and putting goods into the box can be improved.
