Abstract: PURPOSE:To improve the pressing moldability by making a glass material roughly ground in a desired lens shape smooth on its surface layer with a high- temperature gas blown after being heated up to a specific temperature and press forming the product. CONSTITUTION:A glass material 12 which has been roughly ground in a desired lens shape is placed on the plate 13, sent into a preheating oven 1 with the arm 14 and heated with the heater 2 up to a temperature range from the transition point to the fatigue point of the glass material.

Title: Printing head in dot printer
Inventor: UKAI MAKOTO
IPC: B41J2/28
Filed: 1989-10-20
Abstract: PURPOSE:To impart an attenuation to decrease an unnecessary vibration during operation, stabilize an action, and reduce the stress of a spring and the wear of a core by disposing a damper between the movable part and quiescent part of a printing hammer. CONSTITUTION:In a printing head 1, a damper 23 made of a polymeric material or the like smaller in rigidity and larger in attenuation in comparison with a plate spring 7 is interposed between the plate spring 7 serving as a movable part of a printing hammer 8 and a yoke plate 13 serving as a quiescent part thereof. Because the printing hammer 8 is attracted by a core 14 during an inoperation time, the damper 23 is in contact with the plate spring 7 in a com pressed state. At this time, since the rigidity of the damper 23 is smaller than that of the plate spring 7, the power of a permanent magnet 16 for attracting the printing hammer 8 may be identical to that when the damper 23 is not mounted. When a coil 15 is excited and the power of the permanent magnet is de-energized in this state, the printing hammer 8 begins acting toward a platen by the power of the deflected plate spring 7.
