Title: Current source
Inventor: ISHIHARA TSUTOMU
IPC: H03F3/345
Filed: 1982-03-23
Abstract: PURPOSE:To compensate the influence of a channel length modulating effect, and to have high output resistance, by providing an MOST whose source and gate are connected to an input and an output of an inverting and amplifying circuit, and an MOST connected between said source and a DC power source. CONSTITUTION:An input of an inverting and amplifying circuit constituted of an MOS transistor (TR) 11 and 12, and its output are connected to the source of the first MOSTR 13, and its gate, respectively, and also to the source of the MOSTR 13, the second loading MOSTR 14 is connected. Also, the drain of the MOSTR 13 is used as an output terminal 30 of a current source. When the potential of the output terminal 30 rises by a load variation, a drain current of the MOSTR 13 is inclined to increase by a channel length modulating effect, but since an increase of the current is generated in the MOSTR 14, too, in the same way, a voltage drop increases, and the potential fo a node 21 rises. This potential rise is inverted and amplified by an inverting and amplifying circuit, and is sent to the gate of the MOSTR 13 as a potential drop of a node 22, so that an output current does not increase.

IPC: G01J5/06
Filed: 1985-03-08
Abstract: PURPOSE:To prevent the reduction of characteristics by making it possible to uniformize detection sensitivity, by uniformizing the quantity of infrared rays incident to each element. CONSTITUTION:By allowing the lower end 10 of a screen shaped absorbing body 4 to approach an element 6, infrared rays 7 from an adjacent opening part 8 are blocked by said absorbing body 4 and, therefore, incident to the element 6 from the opening part 5 directly above said element 6 and the opening angle theta of said opening part 5 is prescribed by the upper end 11 of the absorbing body 11. If an arbitrary opening angle theta is set, there is no difference between the element 6 at the central part and that at the peripheral part and, therefore, detection sensitivity becomes uniform and the reduction of characteristics can be reduced. A plurality of substrates 21 each having a layer 22 formed thereto are prepared and adhered to form a laminated block. Succeedingly, this block is cut into a plate shape in the direction vertical to the surface of the substrate 21 to be processed so as to obtain a predetermined thickness tc. By this method, the manufacturing of the cold shield for the detector having absorbing bodies 4 arranged thereto is completed.

Abstract: PURPOSE:To increase attraction between a transfer material and toner, to prevent an offset phenomenon and erroneous printing by imparting the potential of a polarity reverse to that of the toner to a surface opposite to the toner sticking surface of the transfer material on a part where a carrying guide plate is installed, on a fixing roll entrance. CONSTITUTION:The transfer material 8 separated from a carrying belt 13 comes into contact with the carrying guide plate 19 installed on the entrance of a fixing unit 10 and is led to the fixing unit 10 while being rubbed. At this time, the contact surface of the transfer material 8 with the carrying guide plate 19 and a fluororesin layer 19a on the carrying guide plate 19 are charged by the friction. In the friction with the transfer material 8, a negative charge is generated on the fluororesin layer 19a being a negative electrifying system. On the contrary, the contact surface of the transfer material 8 with the carrying guide plate 19 is supplied with a positive charge. The electrostatic attraction of the toner 24 of the transfer material 8 is increased by the positive charge newly imparted to the surface opposite to the sticking surface of the toner 24 on the transfer material 8, with respect to the charge toner 24. Thus, on the press-contact part of the heating roller 10a of the fixing unit 10 with a pressure roll 10 fixing is performed while the separation of the toner 24 from the transfer maternal is suppressed.
