摘要:
Provided is an antenna device, having a small and simple configuration, which reduces connection resistance in connections between a film antenna element and a power feeding unit. An antenna device comprises a nonconductive transparent film, which is an insulating substrate having a prescribed optical transmission factor, an antenna element that is formed, upon the transparent film, from transparent conductive material, which is a conductive material having a prescribed optical transmission factor, and a non-transparent conductive power feeding wire. The transparent film and the transparent conductive material are doubled over and pressed upon a portion of one side of the antenna element, which forms a square dipole antenna, such that the transparent conductive material is on the inside, and the power feeding wire is sandwiched therein. By being doubled over, the transparent conductive material has an overlap portion, the two sides whereof electrically connect to one other.

An image feeding apparatus for feeding sheets by separating sheets one by one by a separating device has a pickup arm and a stopper. The uppermost document of stacking documents to be copied contacts and downwardly press down the pickup arm, and then the pickup arm and the uppermost document downwardly press down the stopper so as to make a passage of the uppermost document. After the uppermost document passes through, the stopper ascents by gravity in response to elevation of the pickup arm. The stopper can be reliably operated by a simple and low-cost construction.

A portable trimmer in which the power generated by an internal combustion engine is transmitted to a cutter via a centrifugal clutch and the output power of the internal combustion engine is controlled by operating a manual throttle lever, thereby adjusting the throttle opening of a throttle valve via a throttle wire. The portable trimmer includes a friction member arranged to face the clutch drum of the centrifugal clutch, a moving member which is connected to the friction member and moves the friction member between a braking position where the friction member is pressed against the clutch drum and a non-braking position where the friction member is kept away from the clutch drum so as to release the braking, a manual release device for moving the moving member from the braking position to the non-braking position, and a release restricting device for controlling the behavior of the manual release device.

A near-infrared absorbent is obtained by heating a dimerized thiourea derivative of Formula �1! or �2! and a copper compound: ##STR1## The near-infrared absorbent is used to obtain a near-infrared absorbent resin material having a wide absorption in the near-infrared region, and the absorbent does not substantially decompose at a molding temperature of the resin. Typical examples of the dimerized thiourea derivative are 4,4'-di(benzylthiocarbamoyl)-aminodiphenylmethane, 4,4'-di(benzylthiocarbamoyl)-aminodiphenylhexafluoropropane, and 1,4'-di(dibenzoylthiocarbamoylamino)-2,5-dimethylbenzene, and typical examples of the copper compound are copper stearate and copper .beta.-acryloyloxypropylhydrogenphthalate.
摘要:
In a thermal recording material having a thermal recording layer containing a colorless or pale colored dye precursor and a color developer reactable with the dye precursor upon heating to develop a color of the dye precursor, the color developer is a bisurea compound, for example, Compound A-2. The thermal recording material is superior in stability of background color.
摘要:
An electrostatic capacitive pressure sensor having two silicon diaphragms electrostatically bonded to opposite faces of an insulating member to form two measuring chambers. A silicon base is coupled to the first diaphragm to form a pressure chamber. The insulating member is provided with a through-hole electrode. The electrode and the two silicon diaphragms are operative to measure pressure in the pressure chamber by measuring changes in capacity in the measuring chambers.
摘要:
A level adjusting circuit which adjusts input pulses from an antenna to a level suitable for determining the number of engine revolutions, is connected in a circuit that connects the antenna with a determining circuit. An optimum adjustment of the determination level by manual operation allows the pulses inputted to the determining circuit to be precisely determined at all times.

An ignition timing measuring and display device of an internal combustion engine (1) having a magneto (A) includes a reference RPM signal pulse detector (2) for detecting a reference RPM signal pulse of the internal combustion engine (1) and an ignition noise pulse detector (4) for detecting ignition noise of an electromagnetic wave generated in the vicinity of an ignition plug (3) when ignition is carried out in the internal combustion engine (1) and calculates ignition timing generated by the magneto (A) based on the signal pulse and the ignition noise pulse and displays it. Since the ignition timing of the internal combustion engine can be easily monitored, maintenance can be carried out to the internal combustion engine and an ignition device to realize a necessary operating performance of the internal combustion engine.
