Title: Fet amplifier
Inventor: HANDA KAZUNORI
IPC: H03F3/193
Filed: 1989-11-27
Abstract: PURPOSE:To reduce heat or power consumption without need of a control wire and to facilitate the installation of a radio equipment by operating each FET for amplifying a signal only in the presence of an input signal and interrupting a drain current of the FET in the absence of the input signal. CONSTITUTION:When an input signal is impressed from an input terminal A, part of the input signal is inputted to the FET amplifier via a directional coupler 1 and part of the input signal is led to a detector 2, where the signal is detected and becomes a detected signal. The detected signal is amplified up to a prescribed level by a control signal amplifier 11 and becomes a control signal output. In the absence of the input signal at the input terminal A, the control signal output of the control signal amplifier 11 is preset so as to turn off the current in a transistor(TR) 3. Since no drain current flows in FETs 1-4, 2-5 in the absence of the input signal at the input terminal A, no amplification operation takes place and no waste heat nor waste of power consumption is caused.

Then both the rolls 1 and 2 are pressed against each other with >=5kg/cm line pressure and the quantities of deflection of both the rolls 1 and 2 are set to <=150mum, preferably, <=100mum. Consequently, the nip width can be made small and becomes constant in the length direction of the rolls, and paper wrinkling due to a roll peripheral speed difference is eliminated, specially, when the carrier is thin. Consequently, the wrinkling is eliminated even when the carrier is formed of plural materials one over another like an envelope, and the toner image of good quality can securely be fixed.

Title: Directional selecting device for component
Inventor: UCHIYAMA NORIYUKI
IPC: G01B11/26
Filed: 1989-11-28
Abstract: PURPOSE:To clearly select the direction of a microcomponent by mounting a 1st polariz ing filter on a light projector and a 2nd polarizing filter which differs in polarizing direction from the 1st polarizing filter on a photodetector. CONSTITUTION:The 1st and 2nd polarizing filters 4 and 5 are mounted on the light projector 2 and photodetector 3, the light from the light projector 2 is passed through the 1st polarizing filter 4 to irradiate a specific part of the component 1, and its reflected light is passed throiugh the 2nd polarizing filter and is received by the photo detector 3. Consequently, when the component 1 is in the top direction, linear polarized light is reflected regularly by a mirror surface, so the light has its axis of polarization rotated almost by 90 deg. to become linear polarized light which has the same vibrating direction as the axis of polarization of the polarizing filter 5, so that the light is received by the photodetector 3 after being transmitted through the filter 5. Further, when the compoment 1 is in the bottom direction, the linear polarized light irradiating the component 1 is reflected irregularly by a routh surface and diffused, so the vibrating direction becomes irregular and while almost all of the reflected light is cut off by the 2nd polarizing filter 5, only part of the light is transmitted and received by the photodetector 3. Therefore, the difference in the light reception quantity of the photodetector 3 increases with the directivity of the component 1, which is securely selected.
