Title: Powder ink
Inventor: SHIMURA EIJI
IPC: B41M5/26
Filed: 1989-12-07
Abstract: PURPOSE:To obtain the above powder ink which provides an ink sheet with satisfactory repeatability by specifying the voluminal average particle diameter of powder ink. CONSTITUTION:Powder ink which contains magnetic powder used in an image formation method should have a voluminal average particle diameter of more than 25 mum. It is considered that the attachement of powder ink 11 to the attachement part 9 of this ink layer has occurred as a result of the interaction between the regenerated surface of the ink layer and the surface of the powder ink. That is, it is considered that a van der waals force has worked between the resin component of the regenerated surface of the ink layer and the resin component of the surface of the powder ink. In order to reduce this adhesive force, a magnetic attractive force onto the sleeve of the powder ink 11 has only to be amplified. Subsequently, the magnetic attractive force of one piece of powder ink can be increased. Furthermore, the attachment of the powder ink to the attachment part 9 of the ink layer due to an adhesive force can be reduced.

Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which is operated at a high speed under low power source voltage, in which output of each gate is confirmed even in a standby state, and a delay time is not affected by a frequency of an input signal. SOLUTION: Trs Q1-Q8 constituting a multi-stage inverter are made low threshold voltage because of low-voltage operation. When an input node A is 'L' in a standby state, Trs Qn1, Qp1 of high threshold voltage are connected to Tr Q2, Q3, Q6, Q8 which are cut off. In a standby state, the Trs Qn1, Qp1 for power cut are cut off by chip selecting signals CS, /CS, a sub-threshold current flowing in the Trs Q1-Q8 is interrupted. At this time, since the Trs Q1, Q4, Q5, Q8 are not cut off, the output potential of each inverter is established. The number of transistors required for each transistor for power cut is decided according to a frequency of an input signal, so that only one transistor from among the transistors connected to the Trs Qn1, Qp1 respectively will be turned on simultaneously.
