Title: Exposure optical system for laser printer
Inventor: NAKAZAWA TOSHIHIKO
IPC: B41J2/44
Filed: 1983-01-13
Abstract: PURPOSE:To separate completely two light fluxes which are close to each other at a slit face by providing a concave lens behind an acoustooptical deflecting element. CONSTITUTION:A light flux 22 from a laser oscillator 21 passes through a convex lens 23 for enlarging flux and divided into zero order light 27 and first order diffracted light 26 by the acoustooptical deflecting element 25 according to a signal from a video signal source 24. These two light fluxes are refracted by the lens 23 in the direction to enlarge the angle of separation. After passing through a lens 28, the angle of spreading of light flux increases. Enlargement of light flux in this stage is desirable to form a sharp scanning spot. Enlarged light flux is shaped to parallel light flux by a collimater lens 26. The zero order light 27 is cut off by a slit 30. The distance between the zero order light and first order diffracted light at the position of the slit is much larger than conventional optical system which has no concave lens, and mixing of the zero-order light to the first order light is prevented easily.

Title: Spheroidal graphite cast iron having bainite matrix
Inventor: SUGIURA YASUO
IPC: C22C37/04
Filed: 1985-01-17
Abstract: PURPOSE:To obtain spheroidal graphite cast iron causing hardly cracking by specifying the average grain size of graphite in the bainite matrix of spheroidal graphite cast iron. CONSTITUTION:The average grain size of graphite in the bainite matrix of spheroidal graphite cast iron is regulated to <=20mum. By this regulation, the crack generating energy is increased but the crack propagating energy is reduced, so the total fracture energy is slightly changed. A new use for the spheroidal graphite cast iron can be found because the cast iron hardly causes cracking.

Title: Dot printing head
Inventor: HOKUDOU MASAHARU
IPC: B41J2/26
Filed: 1987-01-15
Abstract: PURPOSE:To increase the magnetic attractive force of an armature and a yoke and also an operating speed by providing a yoke which extends in the inner radial direction beyond the inner radial end of the armature and further, extends in this energizing direction of an armature leaf spring beyond the energizing direction end. CONSTITUTION:The inner ends of legs 25a, 25b, 26a, 26b of yokes 25, 26 are extended to the inner radial end beyond the inner end of an armature 34. In addition, protrusions 26c, 26d which extend further upward beyond the upper end of the armature 34 are provided. The magnetism-coupled area increases by virture of this configuration of the yokes 25, 26 and armature 34 and thereby, the mutual magnetic attraction force can be increased. In the meantime, if a coil 33 is excited, a magnetic flux which is inverted to the orientation of the magnetic flux phi generates, shutting off a magnet ism coupling between an inner leg 22 and the armature 34. Consequently, the armature 34 and in turn, printing wire 36 are displaced in an arrow direction A1 by the spring force of a leaf spring 29 to perform a printing action. If an electric power to the coil 33 is deenergized, the armature 34 is attracted to the inner leg 22 side by the magnetic attraction force of the magnetic flux phi. This process is repeated sequentially to continue the printing action.

Title: Composite valve
Inventor: MIYAKE MEGUMI
IPC: F15B11/05
Filed: 1981-01-19
Abstract: PURPOSE:To reduce the power loss of the composite valve by a method wherein the fluid pressure within the spring chamber of a pressure compensating valve is controlled with a pilot valve and at the same time the communication between the spring chamber of a directional switching valve and a tank can be shut off with a shut-off valve so as to suppress unloading pressure. CONSTITUTION:When the spool 16 of the directional switching valve 2 is operated rightward, the fluid discharged from a pump 1 flows into a loading passage 20a. At this time, the fluid pressure within the loading passage 20a is applied through pilot passages 26a and 51 to the pressure chamber 61 of the shut-off valve 5 and to the spring chamber 52 of the pilot part 31 of the pressure compensating valve 4. As a result, the spool 57 of the shut-off valve 5 is moved  rightward to shut off the communication between the tank 3 and the spring chamber 40 of the pressure compensating valve so as to make the fluid pressure  within the spring chamber 40 correspond to the fluid pressure in response to the  fluid pressure within the spring chamber 52 of the pilot part 31 reinforced by the thrusting force of the spring 49 and said resultant fluid pressure moves the spool 36 leftward to throttle the passage between annular grooves 32 and 33.
