Title: General purpose electronic scale
Inventor: MURAKAMI MITSUHARU
IPC: G01G23/36
Filed: 1995-04-28
Abstract: PURPOSE: To obtain a general purpose electronic scale in which tare measurement, i.e., repeated subtraction of a preset weight value, is carried out for the total weight of an object while measuring the total weight (absolute value) of an object to be measure during the process. CONSTITUTION: A metric indicator 2 comprises a section 15 for indicating various metric values measured at a sensor section and various set data. When the subtraction for an object to be measured is started, the display section 15 is reset to 0 gram by pushing an atuo-zero switch 16. When the value at the display section 15 reaches a subtraction value (lower limit), a subtraction value (lower limit) indication lamp 20 is lighted and the value at the display section 15 is held as it is. A detection output is then delivered to a predetermined mechanism and subtraction for the object is stopped. The operation is repeated and when the total weight of object reaches a minimum value (lower limit), an indication lamp 21 is lighted and the value at the display section 15 is held as it is.  At the same time, a detection output is delivered to a predetermined mechanism and subtraction for the object is stopped.

Title: Image transfer device
Inventor: IZUMI TAKAO
IPC: G03G15/16
Filed: 1989-05-20
Abstract: PURPOSE:To reduce the adhesion of a developer to a transfer member and to readily carry out reversal transfer of a developer remaining on the transfer member onto an image carrier by allowing the transfer member to satisfy specific relations between the critical surface tension rR of a surface layer and the critical surface tension rT of the developer. CONSTITUTION:Where the adhesion of toner to a transfer roller 5 is expressed by work Wa, and contact angles when a liquid is put on the surface of the transfer roller and on the toner surface by thetaRl3 and thetaTl3, Wa = A ( costhetaRl3 + costhetaTl3) holds. When ¦thetaRl3-thetaTl3¦ is greater, Wa becomes lesser. The contact angle of liquid drops on the solid surface is an effective parameter when it is relatively compared with the surface tension. When the difference in contact angle between two types of objects is greater, the difference in critical surface tension is also greater. When Wa is lesser, the adhesion is lesser, and at this time the toner hardly adheres to the roller 5. Where the surface layer and the critical surface tension of the developer are rR, rT, respectively, the transfer roller 5 satisfying inequality is employed to prevent transfer defects.
