Title: Low temperature plasma nuclear fusion
Inventor: MIYANAGA SHOJI
IPC: G21B1/00
Filed: 1989-07-07
Abstract: PURPOSE:To make a low temperature nuclear fusion occur firmly, easily and continuously by using a gas of a highly pure deuterium or a dueterium com pound as a reaction source and by turning the gas into a plasma. CONSTITUTION:A gas of a deuterium or a deuterium compound is introduced into a plasma reaction vessel and an electrical energy is added to the gas t turn it into a plasma. Furthermore, deuterium ions in the plasma are drawn to a surface of a material (it is said representatively to be a material or a palladium or a titan) with which a nuclear fusion occurs by an electrical field negatively self-biased or negatively external-biased. Then the deuterium in an atomic condition collides with a cathode side surface of the palladium side and therewith a nuclear fusion reaction is able to occur on the surface or inside the surface (in a periphery of the surface). In this case, the self-bias is made by designing a pair of discharging electrodes with a geometric heterogeneousness, and the external bias is made by charging a radio frequency voltage added with a direct current bias, so as to make the palladium side to be a negative bias.

Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To unnecessitate compression and expansion processing in a host system and to reduce the cost required for processing of compression and expansion of data in the whole system by equipping a data compressing and expanding means in a removable data recorder. SOLUTION: When recording of data management information and data theirselves is requested by a host system, a compander means 102 is instructed by a system control means to compress the data theirselves leaving the data management information to be uncompressed at they are and the both of them are sent to a recording and reproducing means 103 to be recorded in their prescribed areas respectively. Then, when reproduction of the data is requested by the host system, the data management information read out of the recording and reproducing means 103 are not expanded, the data theirselves are expanded by the compander means 102 and they are sent via an interface means 101 to the host system. Consequently, the data recorder can be fitted to the various host systems and the host system is not required to be equipped with a processing means of compressing and expanding data.

Title: Unidirectional heat pipe
Inventor: KATOU SEIICHI
IPC: F28D15/00
Filed: 1980-12-18
Abstract: PURPOSE: To prevent deterioration of life by using as a driving source a stretching and shrinking mechanism by means of configuration memory alloy.  
     CONSTITUTION: A heat sensing valve 3 that fixes a driving means which consists of a configuration memory alloy 5 that is fixed at its one end and stretches and shrinks with temperature is installed on the cooling side that is on the left inner side of a channel for the working liquid in a heat pipe 1, and the cooling side of the pipe 1 is constituted to close the valve 3 when heated. In this arrangement, when the right end temperature is higher than the left end temperature in the figure, the pipe 1 performs highly efficient heat conduction; when, on the contrary, the left end temperature is higher than the right end temperature, the pipe 1 stops its function to conduct heat. The pipe 1 is, therefore, unidirectional and deterioration and leakage due to deterioration in bellows conventionally used by their stretching and shrinking can be avoided.

Filed: 1982-10-12
Abstract: PURPOSE:To have an effective transport of bobbins through elimination of hand selection by holding bobbins exhausted from an automatic winder with a bobbin chuck of an elevating/sinking device and by selecting them with a bobbin guide while they are on the way of being sent to the tray from an elevated position. CONSTITUTION:If a bobbin B1 on a tray T1 is empty, that is informed as only sensors PS1 and PS3 being sensible, an elevating/sinking body 23 sinks from the position 23b shown by the dot and dash line down to the lowermost position, and a chucking piece 65 intrudes against resistance to the top part of this empty bobbin so as to hold it. With subsequent rotation of a chain 54, the chucking device rises also together with said elvating/sinking body 23 to take out the bobbin B1 from the tray T1. When the elevating/sinking body 23 comes up to neighborhood of its uppermost position, a cam piece 34 is put in engagement with a cam follower 38, and a motion is made from the position shown by the dot and dash line 38a to the one by the solid line. When, further, the elevating/sinking body 23 attains its uppermost position, the chucking piece 65 is opened to drop the held empty bobbin B1 to the dropping position Q in a guide plate 33, and then the bobbin is sent onto a conveyor 84 under the guidance of a guide 33c. Thus bobbins are automatically selected and fed to the spinning machine.

In this case, the magnetic material roller 9 is magnetized in the lattice shape. Therefore, many poles can be magnetized and easily uniformed in magnetic characteristics. Consequently, the magnetization is easy and the development density irregularity is suppressed small.

Filed: 1989-07-12
Abstract: PURPOSE:To allow a stably traveling carrier vehicle to pass a branch point by applying an output signal from an autonomous traveling signal generating circuit to a steering circuit as a steering signal. CONSTITUTION:When the carrier vehicle 1 traveling along a traveling route approaches a branch point and selects a tape dividing side route (there are a straight route and a curve route) as its traveling route based upon a command outputted from the ground board side, a mark detector 8 mounted on the carrier vehicle 1 detects the 1st command mark 10 put on the entrance side of the branch point and switches 14, 17 to be steering mode switching circuits are turned on based upon the detecting signal. The output terminals of a magnetic sensor 7 are short-circuited to forcedly cut out the output signals of the sensor 7 and a generation signal from the autonomous traveling signal generating circuit 18 is outputted from the steering circuit 9 as a steering signal. Consequently, the steering mode of the carrier vehicle 1 is switched from the magnetic guidance traveling to non-guidance autonomous traveling and directly passes the tape dividing section of a magnetic guidance tape 2 by steering control based upon an autonomous traveling signal.

Title: Data transmission method and device
Inventor: ZIJDERHAND FRANS
IPC: H04W56/00
Filed: 1992-07-07
Abstract: PURPOSE: To provide a communication protocol used by a main station and plural mobile sub-stations by using a time slot for transmitting a data packet. CONSTITUTION: A sub-station, provided with a message to be transmitted to a main station, first transmits an access request data packet to the main station. In the case that the sub-station recognizes its own position similarly to the main station, thesub-station impresses the progress of time to the access request data packet, and thus becomes longer and is provided with more information such as a recognition code selected by itself and/or the information related to the length of the message to be transmitted. The main station measures the point of time of receiving the access request data packet related to time slot distribution and transmits the correction of the progress of the time to the sub-station.  After a transmission permission has been recognized, the data packet is transmitted in a length essentially corresponding to the one of the time slot, so as to transmit more information per data packet.

Abstract: PURPOSE:To form a wafer of desired thickness in a distortionless mirror face state by laminating a stopper and a silicon layer on the surface of a substrate, then rotating a surface plate, supplying an alkaline solution decomposed from a polishing agent, securing the substrate to a flat supporting base, subjecting silicon layer to contact-bonding to the front surface of the plate, and polishing it by friction. CONSTITUTION:After a stopper 12 and a silicon layer 13 are laminated on a substrate 11, a surface plate having a smooth surface is rotated, and alkaline solution in which SiO2 fine particles are dispersed is supplied to the surface. The substrate is secured to a flat supporting base disposed in parallel with the surface of the plate, the layer 13 is press-bonded to the surface of the plate, and frictioned to perform its distortionless mirror polishment. Accordingly, since the distortionless mirror-polished silicon layer 13 having the same thickness as that of the stopper 12 is formed on the substrate 11, the distortionless mirror silicon layer 13 having an extremely accurate thickness can be formed on the substrate 11 by setting the thickness of the stopper 12 to the thickness of the layer 13 to be formed.
