Title: Led printing head
Inventor: TANIGUCHI HIDEO
IPC: H04N1/036
Filed: 1994-10-06
Abstract: PURPOSE: To substantially enhance the resolving power by a relatively simple method by arranging lenses so that the optical axes thereof are inclined in a main scanning direction with respect to the perpendicular passing the light emitting surfaces of light emitting diodes. CONSTITUTION: When signal lights are emitted from LEDs(light emitting diodes) in such a state that the lens optical axis of a lens array 9 is inclined at an angle θ in one direction, images are formed at the pitch same to the pitch P of the LEDs 3. Subsequently, when signal lights are emitted from the LEDs 3 in such a state the lens optical axis is inclined at an angle θ in the other direction, images are formed on a photosensitive surface shifted to the other side at the pitch same to the pitch P of the LEDs 3. By forming those images on the same line, an image of density or resolving power substantially twice the constant pitch P of the LEDs 3 can be obtained. As a result, resolving power can be enhanced without altering the forming density of the LEDs 3 of an LED array 2.

Title: Piston for internal combustion engine
Inventor: ITO HIDEKI
IPC: F16J1/04
Filed: 1995-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce slap sounds and sliding resistance between a piston and cylinder by regulating the excessive deformation of the thrust side side wall and antithrust side side wall in the high load running so that a slit formed in a skirt part can be sufficiently deeply set. SOLUTION: A skirt part 24 is formed with two pairs of slits 26 directed from the lower end to a piston crown part. The skirt part 24 is divided by the slits into the thrust side side wall 27, antithrust side side wall and pin boss side side wall 29. The pin boss side side wall 29 is provided near the lower end with a thick wall thickness part 31 for regulating the deformation of the thrust side side wall and antithrust side side wall. When the piston 21 tends to incline by at least a set angle in the high load running even if the slit 26 is provided deeply, the thick wall thickness part 31 regulates the deformation of the thrust side side wall 27 and antithrust side side wall so that the inclination of more than the set angle is restrained.

Filed: 1993-09-30
Abstract: PURPOSE:To dissolve a paper jam easily by providing a cover part opened being interlocked with the takeout of a paper supply cassette, and separating a pinch roller from a carrier roller at the time of the cover part being opened. CONSTITUTION:In the case of a paper jam being generated at the starting edge part of a paper feed passage 26 due to sliding between a pickup roller 19 and sheets, the skew feed of sheets, or the like, a paper supply cassette 61 is pulled frontward out of a cassette insert part. Since pressure to the contact part 57 of a cover part 13 is released at this time, the cover part 13 is moved wide open in such a way as to fall bakcward by the energization of a spring 55, and a pinch roller 23 is largely separated from a carrier roller 22. Accordingly, as to the sheet with the tip part barely reaching the position of a guide plate 28, the tip part comes off the guide plate 28 by the elasticity of the sheet so as to protrude from the open part. The paper jam is thereby dissolved by removing the sheets from the open part of the cover part 13.
