Title: Submersible pump
Inventor: NAGAI TAKASHI
IPC: F04B49/06
Filed: 1980-05-16
Abstract: PURPOSE: To facilitate removal of locking by adding a locking detecting part and the phase inverting circuit of a phase inverting part to a designation controlling circuit to form a designation controlling part, and constituting a submersible motor so that it can be reversed by at least a low frequency when locking is performed.  
     CONSTITUTION: A phase inverting circuit 22 and a locking detecting interface IF concerned with the locking detecting part are added to a designation controlling circuit 18 to form a designation controlling part thereby. Then, a minute series resistance R is inserted into one phase (e.g., W phase) of the three-phase output concerned with an inverter 19 so that the voltage VR across said resistor R is inputted to the interface IF comprising a converting circuit which converts a known alternating current into a direct current, a comparing circuit and a clock circuit. Thereby, when there is locking, the phase sequence of U and V of the three-phase output of the inverter 19 is inverted, so that the submersible motor is reversed by the resulting low frequency. Accordingly, locking can be removed without changing the connection of the cables.

Title: Shape of crystal vibrator support lead for thickness-shear crystal vibrator
Inventor: TADA KOZO
IPC: H03H9/19
Filed: 1990-03-16
Abstract: PURPOSE:To fix two rod-shaped leads and a crystal chip with less solder quantity by specifying the shape of the two rod shaped leads projecting from a hermetic part. CONSTITUTION:Two rod-shaped leads 9, 9' projecting from a hermetic part 13 have a curvature equivalent to a multiple of 3-6 times of its own diameter when viewing the axial direction of the rod-shaped leads 9, 9' and have a circular-arc shape having a thickness of 1/31/6 of its own diameter. Since the rod-shaped leads 9, 9' are thin in this way, the elastic deformation or plastic deformation with respect to a force exerting a crystal chip in the vertical direction in figure is more than that of a conventional support structure and since shock is absorbed by the deformation, shock resistance is high. Since the rod- shaped leads 9, 9' are formed to be circular-arc with a large curvature, it is not required to adjust the interval for each frequency. Thus, the rod-shaped leads and the crystal chip are fixed with less solder quantity.

Title: Vapor growth unit
Inventor: MITANI MASATO
IPC: H01L21/205
Filed: 1984-04-03
Abstract: PURPOSE:To cool a transparent plate with a small amount of cooling gas for inhibiting the reactive product from depositing on the transparent plate, by dividing a vapor growth unit into a reaction chamber and a cooling chamber, and evacuating the cooling chamber to a pressure equivalent to that of the reaction chamber. CONSTITUTION:A vapor growth unit is divided into a reaction chamber 12 and a cooling chamber 16. Air or hydrogen gas is supplied as a cooling gas through a cooling gas feed opening 25 at ordinary temperature. The pressure within the cooling chamber 16 is reduced to a pressure equivalent to that within the reaction chamber 12. According to this method, the thickness of a transparent quartz plate 14 can be decreased substantially, and therefore the flux of heat flow moving from the reaction chamber 12 to the cooling chamber 16 through the plate 14 is increased. Consequently, the surface temperature of the plate can be lowered sufficiently with a small amount of cooling gas, and the silicon crystals deposited on the plate 14 can be decreased remarkably. Thus the deposit is inhibited from increasing continuously.
