Patent JP-H01289304-A (JP)
Title: Frequency mixer
Inventor: SAKUNO KEIICHI
IPC: H03D7/12
Filed: 1988-05-17
Abstract: PURPOSE:To increase the conversion gain from an RF frequency into an IF frequency and to lower the noise figure by setting the absolute value of a pinch- off voltage with respect to a 2nd gate of a dual gate FET more than the absolute value of a pinch-off voltage with respect to a 1st gate. CONSTITUTION:The pinch-off voltage with respect to the 1st gate G1 in a dual gate FET is selected to be within a range of -1.2V to -1.6V, and the absolute value of the pinch-off voltage with respect to the 2nd gate G2 is selected more than the absolute value of the pinch-off voltage with respect to the 1st gate within a range of nearly 1.5V. Thus, even if the pinch-off voltage with respect to the 1st gate G1 is made shallow to increase the conversion mutual conductance gm at the operating point in order to improve the mutual conductance g1, since the pinch-off voltage with respect to the 2nd gate G2 is made deep, a large g1 is obtained without losing the linearity of the gm-2nd gate voltage curve. Thus, a high conversion gain and a low noise figure are obtained.

Title: Inter-pattern detecting and automatic stopping mechanism in exposing and developing device for long base material
Inventor: OUCHI KAZUO
IPC: G03F7/30
Filed: 1986-05-24
Abstract: PURPOSE:To eliminate the influence of the residual development of an unexposed picture forming material at a stripping development section, by automatically stopping the stripping development section between formed pictures when on exposing and developing device is stopped. CONSTITUTION:An auxiliary bar 5 is provided next to a stripping bar 4 and plural optical fiber type detectors 6 are installed to the auxiliary bar 5 in series. Therefore, a photopolymerized compound 3'' after stripping development passes under the auxiliary bar 5. Light reflecting type ones are used for the detectors 6 and the photopolymerized compound 3'' and picture forming long base material 10 are discriminated from each other by utilizing their difference in the reflectivity. Since the inter-pattern space 8 between pattern sections 7 is formed to have a band-like shape, it can be known that a stripping-development line section is in the inter-pattern space 8 when all the plural detectors 6 detect the surface of the base material 10. Such device does not stop unless the stripping development line section is in the inter-pattern space 8 even if a stop signal is issued, but stops at the moment when the detectors 6 detect the inter-pattern space 8.
