Title: Printing apparatus
Inventor: YOSHIDA YUICHI
IPC: B41J19/20
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To restrict a limitation on improvement in drive efficiency due to elimination of a motor in a scanning head type printing apparatus. SOLUTION: When a rotary drive, for example, in a clockwise direction R is started by a rotary shaft 12 after a suction drive of a plunger 1, a freely swingable swing body 3 rotates in the direction R because of a frictional force applied to a gear 4 receiving a driving force of the rotary drive. In consequence, the gear 4 rotatably by an axial support part 3b moves to the direction R and meshes with a carrier gear 8. Meanwhile, when a swing body 6 pressed to the rotary shaft 12 moves in the direction R when receiving the driving force of the rotary drive, an interlock body 7 engaged with the swing body moves in an arrow direction S of the drawing. As a result, an engagement part 7b engages with an engagement part 11b, thereby stopping a movement of an engage body 11 to a direction Q.  At this time, an engage body 10 is not engaged because an engagement part 7a does not engage with an engagement part 11a.

Abstract: PROBLEM TO BE SOLVED: To enable efficient molding irrespective of kinds of resins by mixing thermoplastic resin powder, a filer and a melting assistant, applying a coating at least with the melting assistant, thereafter filling a melt with a mixture produced, heating the mixture so as to melt it and press molding the molten mixture. SOLUTION: A coating by a liquid melting assistant can be provided when a resin powder, a filler and the melting assistant are mixed. Various kinds of formulating compositions are possible depending on an object product, and for instance, pre-heated No.5 silica sand, steramide, polypropylene wax, an anti-oxidant and a ultraviolet-absorbing agent are added into a high-density polyethylene resin powder and they are mixed by a Henschel mixer. A mixture is then loaded into a pre-heated mold, a preliminary press is carried out, and then the preliminarily pressed mixture is heated in a heating oven. The mixture is taken out of the oven after the resin is molten, and a normal pressing is carried out. After the mold is cooled with water, a molded product is taken out of the mold.  This enables a wide variety of molded products to be obtained without any limitation to the kinds of resin and the grain size and amount of the filler.

Title: Sampling circuit using single electron charging effect
Inventor: NAKAMURA YASUNOBU
IPC: H01L29/66
Filed: 1994-02-22
Abstract: PURPOSE:To obtain high sensitivity and high time resolution by connecting the other electrode of a third capacitor to a gate terminal via a fourth capacitor, and so forming first to fourth tunnel junctions as to have single electron charging effect. CONSTITUTION:Switching when an input signal applied to an input voltage terminal 3 exceeds a threshold value occurs as injection of electrons in one electrode of a third capacitor 17 via first, second tunnel junctions 11, 12. An electrode of a sampling gate 1 of the capacitor 17 becomes isolated, and emission and injection off electrons occur only via the junctions 11, 12 by the terminal 3. Since the emission and the injection have a hysteresis for a potential difference between the input end of the junction 11 and the output end of the junction 12, if a composite voltage given from the input voltage, a pulse voltage, a bias voltage exceeds the threshold value even for a short time, one electron is injected, and hence it is switched. Thus, even if a signal is erased, its state is held. Thus, both high time resolution and external reading can be achieved.
