摘要： PURPOSE: To precisely evaluate the liquid repellency for the inside wall of a nozzle by changing the wettability of a liquid so as to irradiate with a vibration wave while continuously changing the shape of the vapor-liquid interface of the inside of the nozzle, and measuring the peak strength of the reflection wave. CONSTITUTION: An injector 1 is dipped in a solution tank 2, air 4 is introduced 7 on the way to the inside of a nozzle part 12 so as to form a vapor-liquid interface, light 11 from a light emitting/receiving device 6 is irradiated from the upper part of the nozzle 12 so as to detect the reflection light from the vapor-liquid interface by an optical element 5 and converted into voltage strength. In this state, when wettability (surface tension) of the solution is continuously changed in a sub-mixture tank 8, the shape of the vapor-liquid interface is changed and to reflection light intensity from the interface is continuously changed so as to reach the maximum, when the interface is flat. The wettability of the solution shows the liquid repellency in the inside wall of the nozzle 12 so that the liquid repellency of the inside wall is found from the solution wettability in the reflection peak. Therefore, when the position of the vapor-liquid is changed, the liquid repellency inside the nozzle 12 can be continuously evaluated in its full length.

摘要： PURPOSE:To accurately calculate a contact angle regardless of the irrequality in the physical quantities of individual liquid droplets by measuring the height of the liquid droplet on a sample from above by a laser microscope while measuring the diameter of the liquid droplet and calculating a contact angle from the values of the height and diameter of the liquid droplet. CONSTITUTION:The liquid droplet 10 bonded to a sample 20 is observed by a laser microscope 60 and the obtained data is analyzed by an image analyser 70 to calculate the radius (r) and height (h) of the individual liquid droplet. The liquid droplet 10 is bonded to the sample 20 by dew condensation or a syringe or a sprayer. When the liquid droplet 10 is small, the shape thereof can be regarded as a part of a sphere and the contact angle 26 of the surface of the sample 20 and the liquid droplet 10 can be calculated from the measured radius (r) and height (h) of the liquid droplet 10. That is, the contact angle is calculated from h=rtantheta in the case of r>=h and from h=2 rsin theta in the case of r

摘要： PURPOSE:To permit the correct operation of a mechanical fuse device for a long time by preventing a connecting member from being broken over necessity due to the reduction of strength by fatigue, even if the mechanical fuse device is used for a long period. CONSTITUTION:A mechanical fuse device is constituted so that a steering shaft 10 and a driven gear 18 are connected through a key 32 inserted into each keyway formed on each member, and when a shearing load over a prescribed value acts between the steering shaft and the driven gear, the connection state of two members is released by the breakage of the key. The key is made of the ceramics having the very small reduction of strength due to fatigue.

摘要： PURPOSE:To provide a piston for an internal combustion engine which can contribute to the reduction of a slap of a piston pin. CONSTITUTION:A piston pin 3 covered with a buffer layer 4 and made of silicon nitride is used. A first pin hole 14 of a piston 1 and a second pin hole 20 of a connecting rod 2 are adapted to face each other so that the piston pin 3 is fitted in the first pin hole 14 and second pin hole 20 and the piston 1 is rotatably supported by the connecting rod 2. The buffer layer 4 has fluororesin as the base material. The thickness of the buffer layer 4 is about 10-600mum. In driving the piston 1, the piston pin 3 abuts against the inner peripheral surfaces 14c, 20c of the first pin hole 14 of the piston 1 and the second pin hole 20 of the connecting rod 2 through the buffer layer 4.

摘要： PURPOSE:To reduce a striking sound caused by heat expansion difference by equipping a pin hole having an internal periphery surface that faces the external periphery surface of a piston pin, forming a fitting mate portion having a heat expansion coefficient larger than that of the piston pin, and forming the shapes of the pin and the pin hole into that of an ellipse. CONSTITUTION:A piston pin 1 made of ceramics is formed into an ellipse cross- sectionally over its overall length, and this piston pin 1 is put into a pin hole 35 which is formed so as to suit the cross section shape of the pin 1, at the boss portion 34 of the side portion of a piston 3 which acts as a fitting mate portion and consists of an aluminum alloy whose heat expansion coefficient is larger than that of the piston pin 1. In this instance, the shorter diameter sides A1 of the piston pin 1 and the piston hole 35 are set in a piston shaft direction Y1 that is a striking sound forming direction. As a result, even if there occurs heat expansion difference, arrangement is made so that clearance at the pin hole 35 may be managed to be small in a striking sound forming direction, and the lowering of a striking sound generated by the piston 3 and the piston pin 1 is realized.

摘要： PURPOSE:To automatically, very accurately, and easily measure the extending dimension of a crack. CONSTITUTION:A video camera 34 takes pictures of a crack produced in a test piece 10 and a picture processor 48 fetches and binarizes the pictures at prescribed time intervals, and then, a picture measuring instrument 52 measures the position of the front end of the crack by detecting the front end on the pictures. When the front end of the crack extends beyond a prescribed point in the pictures, a stage device 32 moves the camera 34 by a prescribed amount against a test piece supporting device 12. A computer 50 calculates the extending dimension of the crack as the sum of the total of displacement values of the front end measured in each cycle after the device 32 is actuated last time and the total of relatively moved amounts of the camera 34.

摘要： PROBLEM TO BE SOLVED: To provide a method for effectively manufacturing multi-pipe (double-pipe, or the like) carbon nanotubes (CNTs) having a structure whereby interior tubes are formed within the CNTs.
SOLUTION: In this manufacturing method, fullerene/CNT hybrid structures are prepared, wherein assembled fullerenes, these being fullerenes that are linked, have been housed within single-layer CNTs. The interior tubes are formed from the assembled fullerenes by subjecting the hybrid structures to electron beam irradiation while in a heated state. It is preferred that irradiation with the electron beams occurs at a temperature of 100 to 500°C and with the electron beams having an accelerating voltage of 80 to 250 kV. According to the manufacturing method of the present invention, multi-pipe CNTs with few defects can be manufactured at a lower temperature and in a shorter period than in the case where the fullerene/CNT hybrid structures are only maintained under high temperature conditions (and electron beam irradiation is not performed).

摘要： PROBLEM TO BE SOLVED: To retain an insulating board mounting an electronic element chip on a heat sink without increasing the number of components. SOLUTION: A recess 32 that is formed so that an angle formed by the inner surface 32a and the bottom surface 32b becomes an acute angle is provided in a heat sink 30, and an insulating board 20 where an electronic element chip 10 is placed is mounted. As a result, even if an electronic element chip module 100 is reversed up and down, a side end section 20a of the insulating board 20 is pressed by the inner surface 32a of the recess 32, thus retaining the insulating board 20 on the heat sink 30, thus eliminating the need for separately providing components for retaining the insulating board 20 and inhibiting the increase in the number of components.
