Title: Method for diagnosing insulation deterioration of power cable
Inventor: KON HIROYUKI
IPC: G01R31/12
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To evaluate the water tree deterioration of a long cable by impressing an a.c. voltage of a predetermined pattern from a lower voltage to a higher voltage for a plurality of number of times, and using as an index as the ratio of a residual electric charge at a first time of the impression and a value after the impression of a predetermined number of times. SOLUTION: In diagnosing the water tree deterioration of a CV power cable or the like, for example, a test cable is grounded after a d.c. is impressed thereto, and then a predetermined a.c. voltage Va is impressed as a first a.c. charging while a step-up time is set to, for instance, 60 sec.. A second charging is similarly carried out with a predetermined voltage Vb higher than the Va after charging in a predetermined pattern. A ratio Q2/Q1 of a quantity Q1 of residual electric charges measured at the first charging of the low voltage and a quantity Q2 of residual electric charges at the second charging of the high voltage increases in correspondence with a degree of water tree deterioration.  A method of continuously impressing an a.c. of two levels as the a.c. current-charging and comparing measured values of residual electric charges of the levels is also carried out to obtain information on the deterioration in the longitudinal direction or the like.

Filed: 1991-09-26
Abstract: PURPOSE:To form a printing image having a plurality of colors by one printing without replacing stencil paper and ink purposely by using heat sensitive ink which is discolored by heating. CONSTITUTION:A heating plate 19 is heated to 128 deg.C in a positionally selective manner and a part of the temp. showing ink in an ink impregnated body 16 is irreversibly changed from a dark bluish green color to a light reddish purpole color by heat. Next, a stamp device is set on a transfer article at a predetermined position and a stamp 17 is pushed down to apply pressure to the stamp device. The ink impregnated body 16 is pressed to stencil paper by a pressure plate 18 and the ink issued from the ink impregnated body 16 passes through the perforated parts of the stencil paper to be bonded to the transfer article. As a result, unless the stencil paper and the ink are replaced purposely, a printing image having a plurality of colors can be formed by one printing.

Title: Method for joining different metals
Inventor: KO TAKAO
IPC: B23K11/20
Filed: 1990-09-18
Abstract: PURPOSE:To stably weld different metals to each other by crimping the different metals and clad metals consisting of the metals of the same kinds as the different metals in such a manner that the metals of respectively the same kinds come into contact, then confining the weld time at the time of resistance welding of the different metals to each other. CONSTITUTION:The reason why the weld time at the time of resistance welding is restricted to <=10ms lies in that embrittled layers are not generated at all at the clad boundaries by joining the above-mentioned metals while partially heating only the necessary joint boundaries. Stable welding is executed even if the thicknesses of the clad metals are small.

Title: Method and apparatus for softening hose
Inventor: ISHIDA TAKASHI
IPC: F16L11/10
Filed: 1988-09-30
Abstract: PURPOSE:To make it possible to easily soften a hose with its external appearance kept as it is by a method wherein the hose is bent in approximately U- shape and one end of the hose is rotated about its axis line and, at the same time, the other end of the hose is rotated or supported rotatably so as to follow the rotation of the one end so as to give rotary bending stress to the hose. CONSTITUTION:A rubber hose H is bent manually in a U-shape so as to put its one end onto an inserting shaft 14, which protrudes beyond a supporting plate 2 and its other end onto an inserting shaft 6, which protrudes beyond a movable plate 4. In succession, the rubber hose H is held by three rubber rollers 9 by pivoting a holding part 13 on the movable plate 4 rightwards and also fixed under pressure by pivoting a holding part 18 on the supporting plate 2. When a handle 21 is turned clockwise under the above-mentioned state, the turning force rotates the inserting shaft 14 clockwise facing upward, the rubber hose H, which is put onto the upper end part of the shaft 14, is rotated in the same direction so as to transmit the turning force to the other end part of the rubber hose H in order to rotate said other end part following the one end. As a result, rotary bending stress is applied to a bent part H4, resulting in softening the rubber hose H.

Title: Photoplethysmograph measuring instrument
Inventor: POLOGE JONAS A
IPC: A61B5/00
Filed: 1997-09-12
Abstract: PROBLEM TO BE SOLVED: To provide a photoplethysmograph measuring instrument to utilize wavelength divided multiplexing. SOLUTION: Before signals from plural light emitters 20 are transmitted to a probe head attached to a reagent and physically disconnected from an examination unit 12, these signals are combined with one multiplexed optical signal inside the examination unit 12. This probe 14 transmits that one multiplexed signal through the tissue of the reagent under examination and afterwards, the transmitted optical signal is processed for measuring the blood reagent level of the reagent. Since the plural optical signals are combined with one multiplexed signal before transmission to the probe 14, a single optical guide like a single optical fiber can be used for sending the signals to the probe 14 so that the execution cost of a system can be reduced and the flexibility of a probe cable 16 can be improved.  Further, the signals from the plural light emitters 20 can be turned from a single spot source to the reagent and measuring accuracy can be remarkably improved.

Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To safely and commonly use a Pb-free solder without generating impurity by a user using this solder by forming an Sn-single plated layer on a wetting surface at the tip part of a soldering copper. SOLUTION: An Fe-plated layer (substrate) 3 is arranged on the whole outer surface of a base body 2 composed of Cu or a Cu alloy. The Sn-single plated layer 5 is arranged on the wetting surface 4 at the tip part of the Fe-plated layer (substrate) 3. A Cr-plated layer 8 is formed at the base end side from the Sn-single plated layer 5. On the Cr-plated layer 8, since the solder is difficult to stick, and the sticking of the solder on the surface of the tip part 1 of a soldering copper is eliminated, the solder is stuck only on the wetting surface 4 applied with the Sn-single plated layer 5 to execute the accurate soldering work. For improving the adhesibility of the Fe-plated layer (substrate) 3, it is desirable to form the Fe-plated layer (substrate) 3 in an inert gas, such as gaseous nitrogen.
