Title: Judgment of quality of heat pipe
Inventor: ITO MASAHIKO
IPC: F28D15/02
Filed: 1990-05-29
Abstract: PURPOSE:To facilitate implementation without use of a heater or the like by a method wherein powder of quick lime is made to adhere to an external surface of an evaporating section of a heat pipe container and absorbs water to cause a chemical reaction and the evaporating section is heated by a reaction heat to judge quality. CONSTITUTION:In judgment of quality of a heat pipe 2, water is injected into a header pipe 3. Powder 5 of quick lime adhering to the outer circumference of an evaporating section 2a of each heat pipe 2 absorbs water to cause a chemical reaction and the evaporating section 2a of the heat pipe 2 is heated by a reaction heat as generated when the quick lime is turned to slated lime. When the evaporating section 2a is heated by the reaction heat, a working liquid sealed into the heat pipe 2 is evaporated and the steam thereof is moved instantaneously to a condensing section 2b to be deprived of heat therewith 2b eventually turned back to a working liquid of a liquid phase. Thereafter, the liquid is circulated back to the evaporating section 2a located below by dead weight thereof. This facilitate judgment of whether the heat pipe 2 operates normally or not by measuring a temperature of the condensing section 2b extended to the outside of the header pipe 3 immediately after water is injected into the header pipe 3 at a water pressure test.

Title: Optical waveguide mode scrambler
Inventor: KOKUBU YASUO
IPC: G02B6/122
Filed: 1986-06-19
Abstract: PURPOSE:To uniformly distribute or couple a multimode incident light beam by interposing an optical branching and coupling part composed of an optical waveguide so that incident light is branched and coupled alternately and repeatedly in a multimode optical waveguide. CONSTITUTION:Center axes of optical waveguides forming a mode scrambler cross each other as shown by dashed lines to repeat branching and coupling and the outer shape of the optical waveguides is a bellows type. An optical branching and coupling part consisting of the multimode optical waveguides varies in branching ratio depending upon the mode distribution unless the mode scrambler which performs mode mixing operation is arranged in front of a branching and coupling part, so when the branching and coupling are repeated, the mode distribution is disordered at every time to cause a failure in uniform branching and coupling, but the bellows type mode scrambler is positioned in front of the branching and coupling part, so that the mode distribution right before each branching and coupling part is approximated to a stationary mode distribution, thereby performing uniform branching and coupling.

Title: Facsimile equipment
Inventor: AKIMOTO NAOTO
IPC: H04N1/21
Filed: 1991-05-17
Abstract: PURPOSE:To utilize the memory effectively by transferring a received document other than a confidential reception document stored in a picture memory to a host device and deleting the document when a communication error due to an occupied memory takes place. CONSTITUTION:When facsimile reception takes place and the received original is sent to a buffer 2 and cannot be outputted, the original is stored in a VRAM 4. When the capacity of the VRAM 4 is not enough, a communication error takes place and a memory full error detection section 5 detects an error. Then a main control section 1 allows a file identification section 7 to identify a file in the VRAM 4. The identification section 7 checks whether or not a reception file in the VRAM 4 is a confidential reception document, an when the document is not the confidential reception document, the file is transferred to a host computer 10 by a file transfer section 6. When the main control section 1 confirms the transfer, a file delete section 9 deletes the transferred file from the VRAM 4. Thus, while the confidentiality of the confidential reception document is secured, an idle area of the picture memory is formed to attain the succeeding reception.

Title: Dc power unit
Inventor: HIRAHARA MINORU
IPC: G05F1/10
Filed: 1986-06-18
Abstract: PURPOSE:To realize connection of a power unit in a live-line state by setting the output voltage of a reverse current preventing diode at a set level when the voltage of an output terminal is lower than a set level and then setting the input voltage of said diode at a set level when the voltage of said output terminal is higher than the set level respectively. CONSTITUTION:When the voltage of output terminals X0 and Y0 are lower than each set level, the voltage of the output side (cathode side) of a reverse current preventing diode D3 is applied to a control circuit in the form of an output voltage detecting signal V0'' by the functions of a voltage detecting means 102 and a voltage switching means 103. Thus a set output voltage level is outputted. While the voltage V0' of the input side (anode side) of the diode D3 is applied to the control circuit as the output voltage detecting signal V0'' when the voltage of terminals X0 and Y0 are higher than each set level. Thus the voltage V0' is kept at a set level and therefore it is possible to secure the voltage approximately equal to the voltage leves of both terminals X0 and Y0 in terms of the voltage V0' in a half state where no load is required for output.
