摘要:
In a tray feeder, in which a drawing section draws a palette from a container and supplies the palette to a pick-up point where a pick-up head of a parts-mounting-apparatus picks up parts, the head starts lowering and halts at a stand-by position before the palette held by the drawing section arrives at the pick-up point. When the drawing section arrives at the pick-up point, the head lowers again from the stand-by position. This mechanism reduces a time necessary for picking up a part.

A non-magnetic material for a magnetic head and a magnetic head produced with the use of such material. For improving the head efficiency and resistance against partial abrasion, the guard piece 11 is mainly composed of CaO, TiO.sub.2 and NiO, with the molar mixing ratio CaO/TiO.sub.2 being 30/70 to 50/50 and the NiO content being 5 to 30 mol %. The head efficiency may be improved, while the partial abrasion may be decreased and the service life of magnetic head may be improved sufficiently.

摘要:
This invention relates to a writing instrument wherein a temporary ink storage member made of a synthetic resin injection molded article is sandwiched between a pen tip and an ink tank. In the present invention, a flange portion for fitting to a predetermined apparatus, which is positioned around an outer peripheral portion of the temporary ink storage member, is formed integrally with a shaft made of a synthetic resin injection molded article. In embodiments of the invention, the temporary ink storage member is made flexible, the shaft is made of a material which is softer than that of the tip holder, and the tip holder is used as a writing thickness display member. The temporary ink storage member can be used as an ink color display member and a cap is used as an application display member. In other embodiment, the cap can be fitted selectively in accordance with types of writing instruments.

Presented are compositions for disinfection of the skin. The composition is characterized in that it contains in an aqueous medium; 0.5 to 10 w/v % of chlorhexidine digluconate, 5 to 25 w/v % of polyoxyethylene alkyl ether, 1 to 5 w/v % of fatty acid diethanolamide, 1 to 5 w/v % of alkyldimethylamine oxide, and macrogol at less than 10 w/v %. The polyoxyethylene alkyl ether and macrogol may be replaced with 10 to 35 w/v % of polyoxyethylene alkylphenyl ether. The composition may further contain 5 w/v % or lower polyoxyethylene lanolin.Since the composition will not solidify even when its solvent is evaporated, the plugging of the outlet opening of the dispenser will be avoided.

A plug for manufacturing a seamless steel pipe is disclosed. The plug includes the surface layer made of molybdenum or molybdenum base alloy coming in contact with a workpiece to be drilled and the core covered with the surface layer. The surface of the core being in contact with the surface layer is formed uneven. According to the invention, the surface layer and the core are strongly joined together, and the life of the plug is elongated.
摘要:
An apparatus for generating a pulse-like constant current with a variable pulse width for use in evaluating thermal characteristics of a laser diode. The apparatus comprises a first constant current (or voltage) circuit constituted by a high-speed amplifer, a second constant (or voltage) circuit constituted by a low-speed amplifier and connected in parallel with the first constant current circuit, a bias circuit for increasing higher the output voltage of the second constant current circuit than that of the first constant current circuit, a switching circuit for turning on and off the first and second constant current circuits in response to first and second timing signals, respectively, in such a manner that the first timing signal and the second timing signal are simultaneously turned on while the second timing signal is turned off only after the first timing signal has been turned off, and a regulator for changing the width of the output current pulse by varying the on/off durations of the first and second timing signals. For evaluating the thermal characteristics of the laser diode, the pulse-like constant current is applied for excitation and the pulse width of the current is varied to change the light emission characteristics of the diodes, which are measured and compared for making evaluation.

A waveform equalizing circuit including a delay line, an attenuator, and a differential amplifier applied with the outputs of the delay line and attenuator is disclosed in which the delay time of the delay line and the attenuation factor of the attenuator are changed in accordance with the characteristic of a waveform applied to the delay line and attenuator.
摘要:
An equalizer equalizes a reproduced waveform reproduced by a thin film magnetic head by reproducing information recorded magnetically on a medium. In the equalizer, the reproduced waveform is delayed to a position of an undershot portion, and is attenuated to an amplitude corresponding to a magnitude of the undershot portion, and the resultant waveform is superposed on the reproduced waveform, to thereby eliminate the undershot portion. Furthermore, by superposing a waveform obtained by inverting the reproduced waveform and amplifying or attenuating the inverted waveform, on the reproduced waveform at a half power position thereof, the width is narrowed.
