Abstract: PURPOSE:To rapidly and cleanly excise the cancer part generated near the ostium uteri with an extremely simple technique without requiring skill. CONSTITUTION:A stem part 1 and a wire part 6 consisting of an electric conductor extending in the diagonal direction of the stem part 1 are provided. The wire part 6 electrically excises the tissue of the uterus 8 successively while the wire part 6 is rotated around the stem part 1 when the entire part of the conductor is rotated around the stem part 1 while a high-frequency current is supplied to the wire part 6 after the stem part 1 of the conductor is inserted into the ostium uteri down to a suitable depth. The part near the ostium uteri 9 of the uterus 8is therefore excised to a circular conical shape when the conductor is rotated one turn.

Title: Optical system information reproducing device
Inventor: IKUTA HIDETSUGU
IPC: G11B7/005
Filed: 1991-10-18
Abstract: PURPOSE:To fast reproduce the multi-value information recorded in a track width direction by arranging a charge modulating element (CMD) at a detector and reading the projection position only of, for example, + or -1st order refracted light. CONSTITUTION:The light of a semiconductor laser 1 becomes the prescribed oval light flux through a lens 2 and a prism 3. Further, the light is divided into two by a polarizing beam splitter 4 and supplied through a detector 10 for servo, a 1/4 wavelength plate 9, and an objective lens 5 to a pit pair on media 6. From the pit pair, the refracted light in accordance with the pit interval occurs and is projected at a detector 8 as a parallel light by a lens 7. The CMD of the detector 8 reads, for example, the + or -1st order refracted light projection position only and bundles the detection information of the front and rear element and improves an S/N. A pattern detector 8 respectively adds the current of the two-divided photo diode, performs the I-V conversion, obtains the adding, subtracting and multiplying outputs and omits the micro positioning beside the noise reduction. By such a constitution, the multiinformation recorded in the track width direction can be reproduced conveniently and fast.

Abstract: PURPOSE:To prevent the durability of outside equipment from lowering by controlling the rotary shaft of a PTO output shaft not to exceed a set speed, in a Power Take OFF (PTO) mode. CONSTITUTION:A comparator 118 compares a speed which is set by a variable resistor 122 with the output of an amplifier 116 and, when the speed of rotation of a PTO output shaft becomes above a set speed, it outputs an H-level signal. The output of a PTO detector 90 and the output of the comparator 118 are inputted in an AND circuit 120. Accordingly, the AND circuit 120 outputs a speed limiting signal when the speed of rotation of the PTO output shaft is above a set speed and at the time of a PTO mode. This signal is inputted in a traveling restricting means 104 to stop an engine.

Abstract: PROBLEM TO BE SOLVED: To eliminate the loss of a signal in case of a fault, make small the signal deterioration due to variation in transmission distance at the time of switching, and enable using a stand-by fiber as it is by using an acoustooptical filter as a branch-inserting circuit and performing gain fixation control as an optical amplifier. SOLUTION: The output of an optical transmitter is equally divided into two, which are made incident on acoustooptic filters 33 and 34 and also equally outputted to both an in-use fiber and the stand-by fiber. The light signals are made incident on other nodes and amplified by optical amplifiers 61 and 62 so as to have their gains controlled to constant values. Their optical amplifier outputs are inputted to the acoustooptic filters 33 and 34, and the light signals of the wavelength sent are branched. Then the two in-use and stand-by light signals are inputted to a selector 42. Then they are inputted to an optical receiver 52. The selector 42 normally selects the in-use side. Once a fault is detected from a decrease in power made incident on an optical receiver 52, switching to the stand-by side is performed.

Title: Fused carbonate type fuel cell
Inventor: KODAMA HIROO
IPC: H01M8/14
Filed: 1986-11-17
Abstract: PURPOSE:To obtain a stable voltage with a starting time shorten and voltage variations eliminated even in the case where load variations arise in operation by composing a negative electrode by a porous body of a hydrogen absorbing alloy. CONSTITUTION:A negative electrode 4 is composed of a porous body of a hydrogen absorbing alloy in a fused carbonate type fuel cell arranged a positive electrode 2 and a negative electrode 4 on both sides of an electrolyte plate 3 including fused carbonate as electrolyte. This enables hydrogen to be blown off by rising temperatures of a cell body to at 600-700 deg.C at the time of starting as hydrogen is occluded and stored in the negative electrode of the fuel cell in a standing duration. Then an electrode reaction of hydrogen oxidation arises immediately in the negative electrode and a given voltage is generated, thereby the starting time can be shortened not affected by a reforming reaction speed even if the speed is slow. And when the load increased rapidly in operation, a voltage can stably be maintained without a voltage drop by compensating a shortage by the blowout of the occluded hydrogen it the increase of the reforming reaction quantity which makes the hydrogen supply quantity to the negative electrode to increase does not meet the requirements.
