Title: Voltage conversion type inverter circuit
Inventor: KOMURO SETSU
IPC: H03K17/66
Filed: 1990-02-20
Abstract: PURPOSE:To expand the utility of a voltage conversion type inverter circuit by applying high speed inversion and voltage conversion to an input signal without using a coupling capacitor to eliminate the need for limiting a frequency (operating frequency) of the input signal. CONSTITUTION:An input signal is amplified noninvertingly by an emitter follower circuit 3 and the amplified signal in phase to the input signal is outputted to a collector follower circuit 15 of an output section and the signal is inputted to a pnp transistor(TR) 13 of the collector follower circuit 15 via a common base circuit 16. Since the signal obtained by the emitter follower circuit 3 is inputted to the collector follower circuit 15 of the output section not through a capacitor, the coupling capacitor is not required. Thus, the limit by the frequency (operating frequency) of the input signal is eliminated and the utility of the voltage conversion type inverter circuit is expanded.

Filed: 1996-02-05
Abstract: PROBLEM TO BE SOLVED: To prevent turbulent flow that makes the conveyance of sheet material unstable and damages an emulsion by providing a static supporting member with a plurality of openings for making drying air pass through. SOLUTION: A dryer cassette 33b is positioned on a static supporting member 44 for supporting sheet material 17 during drying. Drying space 45 id specified between the supporting member 44 and the dryer cassette 33b. The dryer cassette 33b has an assembly of four blower slots 30. These blower slots 30 are positioned opposedly to protuberances 53 in the supporting member 44. Air flow from the blower slots 30 in the cassette 33b goes over the rear edge of the sheet material 17 and is deflected by the supporting member 44 so as to pass through holes 50 in the supporting member 44 as shown by an arrow mark E rather than generating turbulent flow at the rear edge of the sheet material 17. The generation of turbulent flow generated by incoming drying air is thereby minimized.
