Inventor: INOUE TOSHIHARU
IPC: B65B9/10
Filed: 1989-10-31
Abstract: PURPOSE:To diminish variation in welding positions of tear tapes and positional offset of welding parts on the tear tapes for minimizing an increase in mechanical losses and inertia by a method wherein the relationship between a sealing box and a welder is specified and both devices are integrated in a body. CONSTITUTION:A base plate of a welder 1B is mounted on a sealing box 3A, and the elevating cycle of the sealing box 3A is directly utilized for the transfer cycle of the welder 1B. The shaft distance l between a sealing device driving shaft A' and a welder driving shaft B', which works as a driving source for several functions required for welding tear tapes, is designed within a range of 30-150mm, and the driving force is transmitted from the sealing device driving shaft A' to the welder driving shaft B' by means of a gear transmission including detachable idle gears 33-35.

Title: Printing pressure switching unit
Inventor: MIKI ISAMU
IPC: B41J2/30
Filed: 1990-10-22
Abstract: PURPOSE:To improve print quality of a copy medium by providing an impact force varying means for delivering a signal corresponding to an ambient density to a driving current generating means and modifying the waveform of the driving current thereby enhancing the impact force when the ambient density is low. CONSTITUTION:A magnet is excited by feeding a coil Ln in a print head with a driving voltage +60V for a predetermined time. The driving voltage supply time for the coil having direct influence on the impact of a print wire can be modified by the ON time T1 of a transistor Tr1 on common side and the ON time T2 of a transistor Tr2 on dot side. If T2>T1, for example, a pulse having duration shorter than T, is outputted on the output side of a comparator COMA to lower the printing pressure. Consequently, printing pressure can be produced in several stages based on data written into a latch circuit LSI 12. When a thermister TH1 detects +10 deg.C, a printing pressure switching device switches the impact force. A temperature detecting circuit 4 detects temperature upon turn ON of power and sets a low impact force for a temperature higher than +10 deg.C and then detects the temperature with one minute interval. A high impact force is temporarily set for a temperature lower than +10 deg.C.
