Title: Optical adaptor for optical distance measuring device
Inventor: OOTOMO FUMIO
IPC: G01S17/36
Filed: 1983-07-30
Abstract: PURPOSE:To realize a novel small highly manipulable light wave alidade, by allowing distance measuring light waves emitted from a light transmission path means to be incident toward a point to be measured while condensing reflected light waves reflected from the aforementioned point to be measured. CONSTITUTION:An emitting side objective lens system 101 is attached to the inner side wall of a crude oil tank T so that the objective lens thereof is opposed to the liquid surface S of crude oil. Distance measuring light waves emitted from an optical distance measuring device 1 are emitted from the emitting side objective lens system 101 and the reflected light waves are again received by the objective lens system 101 to be returned to the optical distance measuring device 1 through a light wave guide 102. The time delay of the reflected light waves from the liquid surface and distance measuring light waves, for example, phase difference is measured by the optical distance measuring device 1 and the distance between the objective lens system 101 and the liquid surface S of crude oil is precisely measured by said phase difference. By this method, the liquid surface height H of crude oil can be accurately measured.

IPC: F28C3/08
Filed: 1979-10-29
Abstract: PURPOSE: To prevent loss of steam, when the steam is introduced into a heating container for steaming or the like, by decreasing the pressure of the steam through a reducing valve and thereafter controlling a thermostatic valve through the temperature in the container so that a required amount of the steam can be introduced into the container.  
     CONSTITUTION: The pressure of the steam is reduced to approximately 0.5W1kg through the reducing valve 5, and the temperature in the container 1 is detected by a thermosensitive means 2 to control the operation of the thermostatic valve 4, so that a required amount of steam is proportionally introduced into the container 1. Thus, when a product is steamed, the latent heat effect is quite increased, the productivity is improved, and the reduction of energy loss is effected. In the liquid heating, the steam bubbles are subdivided, and therefore the condensation effect is improved. As the flow rate control is made by the temperature detection in the container, it becomes precise and therefore wasteful consumption of the steam can be prevented.
