IPC: B23Q5/34
Filed: 1989-10-03
Abstract: PURPOSE:To damp vibration resulting from reciprocation of a table and grind a plurality of works at one time by oppositely reciprocating an aux. table, on which one work is fixed, in synchronization with reciprocation of table on which another work is fixed. CONSTITUTION:On the body 11 of an attachment, a table 19 is installed capable of reciprocating in the direction to the left and right as shown by arrow, and an aux. table 20 having approx. the same weight as this table is arranged on a path parallel to this reciprocation path. This aux. table 20 reciprocates in synchronization with reciprocation of the table 19. On this table 19 a work W2 is fixed which has approx. the same weight as a work W1, and the table 19 and aux. table 20 can approach or go apart from a grinding wheel G1 to bite into it simultaneously. This damps vibration resulting from reciprocation of the table 19, and two works W1, W2 can be ground simultaneously by one grinding wheel G1. Thus the grinding efficiency is enhanced.

Title: Thermal printer
Inventor: TAKAGI IZUMI
IPC: B41J2/365
Filed: 1993-10-15
Abstract: PURPOSE:To prevent uneven printing density caused by factors such as the heat reserve of a thermal head associated with room temperature change and past printing by determining the duration of a pulse corresponding to the temperature of the thermal head calculated by a head temperature prediction means and determining the interruption time ratio of a short pulse line corresponding to the pulse width. CONSTITUTION:The driving voltage pulse of a heating resistor 14 is composed of the first pulse and a short pulse line which follows intermittently after the first pulse. The breadth of the first pulse is determined by the present head temperature which is estimated by the temperature detected by a thermosensitive element 4 and the printing ratio of past printing data within setting time. The interruption time ratio of the short pulse line is determined according to the determined width of the first pulse. As a result, uneven printing density caused by factors such as the heat reserve of the thermal head associated with room temperature change and past printing is prevented with a simple constitution, thereby enabling fine printing control.

Filed: 1988-10-13
Abstract: PURPOSE:To facilitate working and inspecting of a zoom cam as the machining accuracy is to be guaranteed only at regulation positions by previously regulating the position where two lens groups constituting the zoom lens are to be moved to plural pieces and moving the lens groups to the regulation positions. CONSTITUTION:The plural lens regulation positions are previously set as the positions of on the lens moving loci of a 1st and 2nd lens groups 10A, 10B in the method for driving the zoom lens 10. When the zoom switch 20 is turned off the 1st and 2nd lens groups 10A, 10B are moved to the nearest lens regulation positions among the plural lens regulation positions set from the lens positions of the 1st and 2nd lens groups 10A, 10B at this point of time. The zoom cam 12 is merely required to be able to exactly regulate the positions of the 1st and 2nd lens groups 10A, 10B in the plural set lens regulation positions is this way. Working of the zoom can 12 is thus easier than in the case of continuously and exactly regulating the positions from the telephoto end to the wide end.

Title: Manufacture of metal wire rod
Inventor: OTAKA KAZUYOSHI
IPC: B21C1/12
Filed: 1989-10-04
Abstract: PURPOSE:To prolong the life of a die and to prevent the bent and torsion of a wire rod by adding a reverse tension acting in the reverse direction to a formation drawing tension to the metal wire rod formed on a modified cross section and forming the metal wire rod with its drawing from a circular cross section to modified one. CONSTITUTION:A wire rod 1 is received by a winding drum 26 with the driving of a driving motor 27 and fed from a base metal reel 22. The wire rod 1 prior to forming is first drawn slightly by a back die 3. In this case, the back die 3 gives the wire rod reverse tension as the reaction against the drawing. The wire rod 1 drawn just as the circular cross section is further formed in the specific shaped cross section by a forming die 4 and wound on a winding drum 26. The life of the die 3 is therefore prolonged because of a reverse tension being applied on the wire rod passing through the forming die 4 and the load in the drawing direction applied on the internal face of the forming die 4 being reduced. Simultaneously the bent and torsion of the formed wire rod 1b are prevented as well.
