Title: Ladder type piezoelectric filter
Inventor: TANAKA YASUHIRO
IPC: H03H9/58
Filed: 1979-01-11
Abstract: PURPOSE: To miniaturize a ladder type piezoelectric filter by using several piezoelectric resonators whose ratios of longitudinal length to lateral length are set to 0.7 or less.  
     CONSTITUTION: Piezoelectric resonators C 1 ∼C 4  have ratios of longitudinal length to lateral length set below 0.7. Those resonators C 1 ∼C 4  are arranged in case body 14 made of insulating resin such as epoxy to constitute a ladder type filter making use of its longer-side vibration. Thus since ratios of longitudinal length to lateral one are set below 0.7, the height is reduced by not less than 30% as compared with a conventional one, miniaturizing the constitution. Simultaneously, the vibration  level and frequency of the shorter-side resonance level of a piezoelectric resonator  can be fixed sufficiently away from the vibration level and frequency of the longer- side resonance level, so that the adjacent spurious of the center frequency of the  fillter can greatly be suppressed.

Filed: 1978-01-17
Abstract: PURPOSE: To reduce the shock and drive forque upon insertion and discharge of copy paper by forming a clearance, which is larger than the maximum diameter of toners and smaller than the elastic deformation thickness upon pressure fixation of the copy paper, when the upper and lower rigid rollers are stopped for fixation.  
     CONSTITUTION: Bearings 11 and 12 having a larger diameter than the center portions of upper and rollers 1 and 2 are mounted on the both ends of the rollers 1 and 2 such that a clearanced is formed between the rollers 1 and 2. The clearance d is made larger than the diameters of the toners and smaller than the elastic deformation thickness upon the pressure fixation of copy paper. Thus, when the copy paper P is inserted, the roller spacing is widened to b so that the shifts of the rollers with respect to a pressure spring 8 are b - d and d 1 , respectively. In other words, as compared with the one, in which the rigid rollers are in contact, the shifts can be reduced by d. As a result, the shocks upon insertion and removal of the paper can be reduced together with the drive torque.
