Title: Supply of liquid material and its device
Inventor: KIMURA KIYOHIRO
IPC: B05B9/03
Filed: 1993-12-08
Abstract: PURPOSE:To avoid the forming of bubbles efficiently and enable the motion of an inflow valve to follow the motion of a piston adequately by filling a measurement chamber with a liquid material from a bypass route by a negative pressure in the measurement chamber which generates when the piston is pulled out. CONSTITUTION:An insertion part 23B is introduced into a measurement chamber 24 completely in a state in which a piston 23 is inserted into the measurement chamber 24, and if the piston 23 is caused to ascend from this state into an arrow (a') direction, the insertion part 23B ascends in the inflow chamber 21. Consequently, the inner volume of the inflow chamber 21 changes, resulting in the suction of a liquid material from a material inflow port 22. In addition, a negative load generates on the interior of the measurement chamber 24, and consequently, a pressure in a material reservior 34 and a bypass route 36, both being connectively formed. Thus an iron cube 31C in a bypass operating valve 31 opens, then the liquid material sucked into the inflow chamber 21 is absorbed into the bypass route 36 through the bypass operating valve 31 to be poured fully into the measurement chamber 24. In this way, the internal pressure of both material reservior 34 and bypass route 36 is prevented from becoming vacuum.

IPC: G03B27/62
Filed: 1989-12-29
Abstract: PURPOSE:To copy all of data without mistakes by resetting an automatic original transporting device to an original state upon receipt of the data indicating that a safety switch restores a stationary state. CONSTITUTION:A controller 13 on a copying machine 13 side executes stationary state processing and stores the data on the operating state received from the controller 13 of the automatic original transporting device 10 into a memory 15 when the safety switch 17 turns off. The switch 17 turns on and whether the transporting device 10 is used when a front cover 21 is held open or not is checked in accordance with the data of the memory 15 when the switch 17 is returned from the non-stationary state to the stationary state. A data transmission means sends a continuous copying signal to the controller of the transporting device 10 when the transporting device is used. The resetting means in the transporting device 10 is returned to the state before stoppage and the state before the stop is thus restored without making an initializing operation. The copying is thus executed continuously without the drop-out of image formation and original transportation and without the mistakes even if the there is an emergency stop while the continuous operation is executed.

Title: Vapor growth device for organic metal
Inventor: KAGEYAMA SHIGEMI
IPC: H01L21/205
Filed: 1989-12-26
Abstract: PURPOSE:To realize such crystal growing method that can form a substrate having a thin growth layer and good crystallizability and, at the same time, fill up the uneven surface of the substrate to a flat surface by fitting a driving mechanism to a susceptor and vibrating a substrate to be grown. CONSTITUTION:When an AC voltage is applied across a piezoelectric element 10 while a crystal is grown, the element 10 vibrates in correspondence to the frequency of the voltage and the kinetic energy of the atom, molecule, or growing species of the growing crystal is relatively increased. At the same time, the potential energy at the surface of a substrate 4 is also increased. As a result, separation of adsorbed growing species also increases and the crystal is preferentially grown at a low-potential position. Accordingly, the crystal growth advances in such a way that a unique surface is eliminated from the substrate 4 and the uneven surface of the substrate 4 is filled up to a flat surface. Therefore, a substrate having a thin growth layer and good crystallizability is grown and, at the same time, the uneven surface of the layer is filled up to a flat surface.
