Filed: 1988-03-02
Abstract: PURPOSE:To obtain a gas lighter capable of easy ignition and being hardly extinguished even in the presence of wind, by providing a plurality of jet ports in a side surface of a jet pipe. CONSTITUTION:A plurality of jet ports 2 are provided in a side surface of a jet pipe 1. A fuel gas is dispersely jetted through the jet ports 2, sideways from the jet pipe 1 to the surroundings.

Title: Magnetic recording and reproducing device
Inventor: MATSUSHIGE HIROMI
IPC: H04L25/40
Filed: 1980-04-11
Abstract: PURPOSE:To prevent data error by providing a variable delay circuit of which the delay time increases when input signal frequency increases to the prestage of a data reproducing circuit system and increasing the phase margin of the reproducing circuit system. CONSTITUTION:The output signal of an equalizing circuit 13 is inputted via a variable delay circuit 25 to a pulse shaping circuit 14. The circuit 25 has such delay characteristics that the delay time increases with a rise in input frequency. A peak shift is produced in a read signal 20, and the phase advances. The quantity of this peak shift increases in proportion to the recording frequency. On the other hand, the delay time of the circuit 25 increases in proportion to the frequency of the input signal. Hence, it turns out that when viewed from the data reproducing circuit system the read signal 20 is compensated of the peak shift. Consequently, if the delay characteristics of the circuit 25 are adequately set, the read pulses 21 can assure sufficient phase margins. Hence, data errors are prevented by such constitution.

Abstract: PURPOSE:To detect quickly the shape and the position of an object with a high precision, by making only the shade image of the object incident to a photographing device as a black-level picture signal and making only the direct reflected light incident to this device as a white-level picture signal. CONSTITUTION:A substrate 2 which an object 1 to be detected is put on is illuminated with a certain brightness from the direction, which is inclined left at 45 deg. from the perpendicular by a light source 3. An image pickup camera 4 is arranged in the direction inclined right at 45 deg. from the perpendicular. The light source 3 is so set that images of the object 1 and the substrate 2 are taken as white-level pictures having the same gradation. Only the shade part of the object is taken out as the black-level picture signal from the image pickup camera 4. Thus, the position and the shape of the object are detected with a high precision only by the comparison of two densities of logical ''1'' and ''0''.

Abstract: PURPOSE:To detect a recording pit even when its size is smaller than a light spot by making light generated by a magneto-optical effect interfere with light diffracted by curved surfaces of an objective lens through an analyzer, splitting it into two beams and detecting them with a multidivided detector. CONSTITUTION:Output signals of differential amplifiers 5 and 11 are further differentially detected by a differential amplifier 15 to produce a regenerative signal (for pit position recording) 16. This signal 16 is at a negative constant level in a downward magnetization area, and is at a positive constant level in an upward magnetization area, and moreover, the level is changed from positive to negative and from negative to positive in a mixture area of the upward magnetization and the downward magnetization where a domain edge is positioned in the light spot. On the other hand, output signals of differential amplifiers 8 and 14 are added up by an adding amplifier 17 to produce a regenerative signal (for pit edge recording) 18. The signal 18 is at zero level in the downward and upward magnetization areas, becoming a regenerative signal having a positive or negative peak at a domain edge. By detecting this peak position, the domain edge can be detected, and information recorded in the pit edge recording can thus be reproduced.
