Title: Heat roll fixing device
Inventor: INAGAKI SANJI
IPC: G03G15/20
Filed: 1982-02-05
Abstract: PURPOSE:To completely prevent offset development without using an offset preventing agent by preparing an insulating layer for a press roll so as to charge by friction an offset preventing layer for a heat roll with the same polarity as a toner image. CONSTITUTION:An offset preventing layer 4 consisting of fluoric resin is laminated on the external layer of a metallic roll 2 inside the heat roll 1 and a rubber-like elastic layer 8 including carbon black is laminated on the external surface of a metallic roll 7 inside the press roll 6. When copying paper B holding a positively charged toner image A is fed between the roll 1, 6 to fix the toner image A, the surface of the heat roll 1 is charged by friction with the same polarity as the toner by the action of carbon black included in the rubber- like elastic layer inside the press roll 6, so that negative charge is prevented and superior copying having no offset can be obtained from the initial stage of fixing. Thus the offset phenomenon can be completely prevented without using the offset preventing agent.

Title: Temperature compensating type photo detector
Inventor: MAEDA AKIRA
IPC: H01L31/02
Filed: 1982-02-08
Abstract: PURPOSE:To stabilize a measuring precision of a photo detecting element irrespective of external temperature change through compensation of temperature of a photo detecting output, by installing a photo conductive type detecting element on a Peltier element and cooling the photo detecting element corresponding to an ambient temperature. CONSTITUTION:If the temperature around a photo detector 1 rises, temperature detecting signal from a thermocouple 7 increases, and a current flowing to a Peltier element 8 increases as a result of the increase in a current value outputted from a power source control circuit 8 proportioning the temperature detecting signal to cool a metal body 9. Meanwhile, if an ambient temperature falls, a current flowing to the Peltier element 8 decreases, the cooling action of the metal body 9 reduces. This enables controlling of the cooling action of the metal body 9 corresponding to fluctuation in an ambient temperature, and causes the temperature to be stabilized to an approximately constant value, for example, 0 deg.C. An SePb photo detecting element 14 is secured to the metal body 9 through a ceramic substrate 16, and thereby it is held in temperature approximately equal to that of the metal body 9.
