Title: Paper feeder
Inventor: KAMEYAMA TOSHIAKI
IPC: B65H3/06
Filed: 1985-04-19
Abstract: PURPOSE:To prevent the skew and jam of paper with a low working accuracy roller by setting the center of a pick-up roller to the paper feed reference side from the center of paper feed direction in a cassette with each one roller for pick-up, feed and reverse. CONSTITUTION:A pick-up roller 3, feed roller 5 and reverse roller 6 are respectively constituted from one roller. A roller 6 blocks blanks P except for the uppermost thereof fed from a roller 3 between the roller 6 and the roller 5. When a plurality of blanks P are inserted, the roller 6 rotates in the opposite direction to the feed direction to separate other blanks from the uppermost blank P and block the feed. Also, since the center O1 of the roller 3 is located at the feed reference side 1c from the center O of blank P in a feed cassette 1, when the roller 3 rotates to send the blank P in the direction a, the resistance force of the blank P in a portion at the side 1c from a straight line l1 of the blank P is smaller than that in the other portions so that clockwise rotational moment acts on the blank P which contacts the side 1c while being fed without any jam or the like.

Abstract: PURPOSE:To detect a fine and very thin floating metal powder in a wide range of an oil tank by a method wherein a pair of electrodes using a thin film metal is made to interlock on an insulation substrate in a comb as opposed to each other to measure a pulse voltage generated by the metal powder. CONSTITUTION:Metal for electrodes is deposited on a highly insulating substrate 6 and formed in a comb by etching or the like. A counter interval (t) of electrodes 1 and 2 ranges 1-50mum and the width of the electrodes 1 and 2 ranges 3t-8t. Metal composing the electrodes 1 and 2 employs Ta, W, Pt, Au or the like that would not make an insulating portion or a semiconductor by oxidation. In the detection, a sensor is immersed into a lubricant and a voltage of 30-50V is applied between the electrodes 1 and 2. With the existence of metal abrasives, a pulse voltage is generated in the electrodes 1 and 2 to be detected with a detector 5. The level of the height of the pulse voltage is proportional to the squaring of a particle size and the frequency of the pulse is proportional to a particle density. Thus, the particle size and density of the metal abrasives can be learned in the lubricant by detecting the pulse voltage and the frequency.

Filed: 1987-04-08
Abstract: PURPOSE:To evaluate the characteristics of a light-emitting diode by a noncontact method in the wafer stage by a method wherein the optical luminescence, which is generated when a laser beam is obliquely projected on the surface of a wafer, is allowed to be reflected by a reflecting mirror and then detected by a photomultiplier.

Optical excitation attributable to the energy of the beam L3 results in a luminescence L4, which goes into a reflecting mirror 6 for the generation of a reflected beam L5. The reflected beam L5 goes into a spectrograph 7, and is amplified by a photomultiplier 8 for measurement. In this way, the characteristics of a light-emitting diode may be rated in the wafer stage by using a noncontact method.
