Abstract: A process for making a noise absorber carpet including a fabric layer portion and a resinous backing layer portion including the substantially concurrent steps of continuously feeding a softened resinous backing material from a backing resin feeder onto a backing roll to form a continuous resinous backing sheet thereon, and continuously feeding a heated continuous fabric sheet via a fabric roll onto the backing sheet continuously formed on the backing roll, wherein the backing roll includes spike depressions and perforation pins on its surface, and wherein the fabric roll is located close to the backing roll to press the fabric sheet against the backing sheet as the sheets proceed between the rolls and mold spikes and perforations on the backing sheet, the backing roll being cooled to a temperature range between 10 degrees Celsius and 50 degrees Celsius with a cooling medium to harden said spikes and perforations and provide bonding between the fabric sheet and the backing sheet.

Abstract: A process for making a noise absorber carpet including a fabric layer and a resinous backing layer, the process including providing an uncured resinous backing layer within a mold having perforation pins, heating the backing layer to activate the resin, providing a fabric layer, pressing the fabric layer into the backing layer while maintaining the heating process to the backing layer, and providing a cooling medium to cool the mold to fix and cure the perforations within the backing layer thereby forming noise absorber perforations in the resinous backing layer.

Abstract: A noise absorber carpet comprised of a fabric layer portion and a resinous backing layer portion is provided. The fabric layer portion and the resinous backing layer portion are heat bonded with a press into the noise absorber carpet, and the press includes perforation pins and a cooling medium. The resinous backing layer portion is provided with noise absorbing perforations formed by contact with the perforation pins of the press and cooled by the cooling medium. The perforations having been cooled by the cooling medium with the press simultaneously with the bonding of the resinous backing layer portion with the fabric layer portion and the cooling of the press by the cooling medium, thereby providing for instant curing and fixation of the shape of the perforations.

Abstract: Combined boards are taught that comprise a second board substrate (12) having a through bore (14) formed therein, a first board substrate (10), and a connector pin (40, 50) received in the through bore (14) of the second board substrate (12). The first and second board substrates overlap such that the through bore (14) of the second board substrate (12) is covered by a first surface (10b) of the first board substrate (10). The connector pin is fusion bonded to a circumferential surface of the through bore (14) and the first surface (10b) of the first board substrate (10).

Abstract: An object of the invention is to provide a tip for stick use without any movable portion and any sliding portion, which is monolithically formed to be flexibly deformable having a restoring function as well as a simple constitution, and a stick shod with the same. The tip is mainly constituted of a lower portion 1 for contacting the ground, an upper portion 2 whereon a hole 6 to be inserted with the stick 3 is opened and a flexibly deformable portion 4 for connecting aforesaid lower portion 1 and upper portion 2 which is equipped with an annular concavity 5 on a peripheral surface. The above-mentioned three portions 1, 2 and 4 constituting the tip are fabricated monolithically from an elastic material.

Abstract: The object of the present invention is to provide a flexibly elastic and light reflective tip for stick use, which improves the safety in use of a stick. In the present invention, this object is attained by providing an irregular reflecting surface on the upper portion of the tip by forming a cylindrical metal having an excellent light reflectivity by plating or pressing, to have a cross-sectionally serrated or wave form for more reflectivity.

Abstract: An apparatus for rotating and driving an antenna device in a radio transmitter and receiver which can simply increase and decrease the driving torque by variation in weight thereof. This apparatus comprises a rotary body rotatably mounted on a main housing and supporting the antenna device thereabove, and one or more driving units detachably mounted on the main housing. The rotary body is connected to an input gear rotatably provided on the main housing through a gear mechanism. Each of driving units has a driving source and a keyway gear connected through the gear mechanism, the keyway gear being meshed with the input gear when the driving unit is mounted on the main housing. Thereby, the driving torque required for rotation of the antenna device is adjusted by increase or decrease in number of the driving units.

Abstract: A low-temperature liquefied gas outflow device wherein an outflow nozzle having a plurality of through-holes is provided through the base of a heat-insulating container having an opening at the top, and a cover member closing the opening, a control device for selectively opening or closing any desired number of the plurality of through-holes provided in the outflow nozzle is provided. The heat-insulating container has a level sensor located within the heat-insulating container, a liquefied gas supply conduit running through the cover member, a vaporized-gas exhaust conduit provided in the cover member, and a check valve inserted into the liquefied gas supply conduit, operating in response to a signal from the level sensor. The control device for selectively opening or closing the through-holes comprises a plurality of valve elements for selectively closing the through-holes, and an elevation cylinder for controlling the operation of the plurality of valve elements.
