在日中经济协会的热情安排下,我们参观了横河电机所的研究开发部和有关试验室,看到了三个进行中的研究项目。第一个是溅射应变片。机械产品应力测试所用的应变片一般为丝式。由于胶片、蠕变等原因,粘贴的某些部分容易脱落。横河正在研制一种溅射应变片,可在真空度10~(-6)～10~(-7)乇的情况下,实现离子溅射,这样的应变片不会出现上述使用中的缺陷,目前研制工作已接近完成。第二个是新型压力传感
Under the enthusiastic arrangements of the Japan-China Economic Association, we visited the Research and Development Department and related laboratories of Yokogawa Electric and saw three ongoing research projects. The first is a sputter strain gage. The strain gauges used for stress testing of mechanical products are generally wire style. Due to the film, creep, etc., some parts of the paste easily fall off. Yokogawa is developing a sputter strain gage that can achieve ion sputtering at a vacuum level of 10~(-6) to 10~(-7) Torr. Such strain gages do not suffer from the aforementioned defects in use. At present, the development work is nearing completion. The second is new pressure sensing
