本発明は緩衝用ばねに関して計測用器具に係わるもので
ある
従来は此れ等の緩衝用ばねは金属線をコイル形状にした
ものが主体であった。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a measuring instrument relating to a shock absorbing spring. Conventionally, such shock absorbing springs have mainly been made of coiled metal wire.
而してそれはソリッド形状のものであった、その為にコ
イル自体にばね圧力を計測することは不可能であった。However, it was a solid shape, so it was impossible to measure the spring pressure on the coil itself.

い。此の微小加工測定に於いて微小圧力を計測するに際
して時間的即応性、しかも瞬間的に計測をめる必要があ
り、又其処に価値性があるといはれている。Recently, there is a lot of demand for micro-processing measurements such as micro-machines, processing, and pressure. In this microfabrication measurement, when measuring minute pressures, it is necessary to be able to respond quickly in time, and moreover, to measure instantaneously, and this is said to have value.
従来のものでは、計測装置とコイルばねは別のものとし

体のその接続部分の強度が劣弱の為に故障が多いという
欠点をもっているのが現状である。この故障は製品用途
によっては致命的欠陥といえるものである。In the prior art, the measuring device and the coil spring are separate devices that need to be connected to the device. Connecting these minute parts was a very difficult process in the past, and even if it were possible to manufacture a product, it would have required a great deal of skill and a relatively complicated process. Currently, the product has the disadvantage that it often breaks down because the strength of the connection part of the product itself is poor. This failure can be said to be a fatal defect depending on the product use.
此処に本発明のものを提供する根拠が存在する。Therein lies the basis for providing what the present invention provides.

分も従来に比して堅牢の構造にすることが可能である。That is, in the present invention, the optical fiber itself is installed in a coil spring, so the pressing force applied to the optical fiber itself can be immediately read, and the connecting part is also smaller than the conventional one. It is possible to create a robust structure.

ことも可能である。The present invention will be described in detail. FIGS. 1 and 2 are shape diagrams of an embodiment according to the present invention. FIG. 1 is a perspective view of the spring configuration of the present invention. FIG. 2 is an enlarged partial view showing the internal structure of the spring according to the present invention, and is a partially sectional perspective view. 1 is a filled tube filled with optical fibers according to the present invention, which is formed into a coil shape as shown in the figure. The central portion 11 is not a coil shape but a straight line shape. For this reason, the pressing force that this coil receives is 1
This is due to it being the first place to receive it. Reference numerals 12 and 13 denote both terminal portions, which are connected to the optical fiber to the transmitting device and the receiving device, respectively. 21 and 22 are terminal parts for this purpose. In FIG. 2, 3 is an optical fiber. 4 is a protection tube for holding the optical fiber. The material of this is limited to metal, and may be made of an elastic material such as resin. 5 is fine powder. There is no problem with this even if the material is made of alumina. It's just unfired and after degreasing. Of course, the fine powder itself is fired, but when measuring the pressing force applied to the coil using a coil filled with optical fibers having this structure, we first need to measure the corresponding wavelength. If a signal is transmitted through the terminal 21, the quantity and quality of the pressing force applied to the coil can be detected by the receiving device via the receiving terminal 22 by changes in the wavelength of the optical fiber 3. It's something you get. The feature of the present invention is that it has extremely superior element responsiveness and instantaneousness when compared to other products of this type. Furthermore, in the embodiment of the present invention, it is also possible to pack a plurality of 3 optical fibers.
