Abstract: PURPOSE: To prevent freeze with a small amount of heat by arranging one end of a heating pipe at the part where fear of freeze exists, of a ship which navigates and executes work in cold sea area in winter and, arranging the other end at a heat source, and allowing the fluid in the pipe to be heated and circulated through the utilization of waste heat.  
     CONSTITUTION: A heat pipe 1 in which a heating fluid such as Flone is charged is arranged at the position 3 where snow melting and prevention of freeze are necessary on a hull. At the end part 1a of the heat pipe, a water passing part is formed through a fin, and the hot water through utilization of the heat procured from the motors and generators on the hull is allowed to circulate. The heating fluid in the heat pipe 1 is heated by the hot water and evaporated, and cooled at the other end part 1b and condensed and liquefied. A condensation heat is released at that time, and the part 3 is heated, and thus snow melting and prevention of freeze can be carried-out effectively.

Title: Bonding process of semiconductor substrate
Inventor: UEMOTO TSUTOMU
IPC: H01L21/60
Filed: 1985-05-29
Abstract: PURPOSE:To connect different kind of semiconductors with high concentration without any disconnection due to thermal expansion by a method wherein an insulator substrate is passed through by electric wirings to bond two different kind of semiconductor substrate s using Indium.

Title: Processing circuit for vertical synchronization signal
Inventor: OKAMOTO NOBUYUKI
IPC: H03G11/02
Filed: 1994-04-29
Abstract: PURPOSE:To prevent deterioration in image quality by reducing a potential of an anode of a diode with an impedance element when a vertical synchronization signal fed to a signal processing section is positive so as to clamp property a base level of the vertical synchronization signal thereby eliminating a noise component. CONSTITUTION:A vertical synchronization signal SVc obtained by applying a base clamp to a vertical synchronization signal SV received at an input terminal 21 with a capacitor 22 and a diode 24 is fed to a signal processing section 28. In this case, a polarity discrimination section discriminates the polarity of the signal SVc and gives a SD to an impedance element 29. When the signal SVc is positive, an anode potential of a diode 24 is decreased by the impedance element 29 to keep a proper clamp level to the SVc received by the signal processing section 28 even when a forward voltage of the diode 24 is small due to a large duty factor for a base level period of the vertical synchronization signal. Thus, a proper clamp level is obtained independently of the polarity of the vertical synchronization signal with simple configuration.

Title: Apparatus for predicting disconnection of water cooled cable
Inventor: MATSUDA ISAMU
IPC: G01R31/02
Filed: 1982-06-29
Abstract: PURPOSE:To make it possible to predict the disconnection of a water cooled cable, by a method wherein the change in the cross area of the water cooled cable is detected when a comparison value with impedance at a normal time exceeds a predetermined value because the change in the cross area of said cable appears largest at the change in DC resistance to output a signal to an alarm circuit. CONSTITUTION:The ratio of the voltage drop VK of a water cooled cable 2 detected by a voltage drop detector 6 and the voltage Vo of a main circuit detected by a transformer 5 for a measuring instrument, that is, the ratio V= VK/VO is compared by a first comparator 7 and this value V appears as the change in the impedance of the water cooled cable 2. Therefore, it is compared to the impedance ZR of the water cooled cable 2 as a new one from a reference signal input terminal 8 by a second comparator 9 and, when a V/VR value exceeds a predetermined value, a signal is outputted to an alarm circuit. As mentioned above, by detecting the impedance change by converting the same to voltage change, the change in the cross area of the water cooled cable 2 can be detected in good sensitivity.
