Title: Device for measuring brightness and color tone of skin
Inventor: MORITO YUKO
IPC: G01J3/50
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To measure the relative brightness and color tone based on reference brightness and color tone accurately only by measuring reflecting optical intensity even when the irradiated optical intensity of each light emitting element is different. SOLUTION: Red light and green light are sequentially cast from a light transmitting part 3 formed on the tip of a probe 2 on the measuring part of skin and also irradiated on the optical axis of a photodetector 4 at a equal angle. This device is formed in this way. Therefore, the respective intensity of reflected light can be individually measured with one photodetector 4 and can be measured at the same time under the equal reflecting condition. Furthermore, a color-reflection optical intensity is normalized by respective standard reflected light intensities Ro and Go when the red light and the green light are irradiated on a standard measuring object surface. Therefore, even when the optical irradiation intensities of respective light emitting elements 5R and 5G are different, the relative reflected light intensities can be accurately measured. Then, the brightness of the skin, which is indicated by the sum of the respective normalized reflected-light intensities R and G, and the color tone of the skin, which is indicated by the difference of the above described respective color normalized reflected-light intensities R and G, are displayed stepwise.

IPC: E21D9/04
Filed: 1991-09-10
Abstract: PURPOSE:To increase reaction force in a front-jacking method by connecting a temporary pipe-roof to a reaction-force coffer body in advance, and using the circumferential resistance of the pipe-roof. CONSTITUTION:Vertical steel pipe-roofs 2a, 2c and a horizontal steel pipe-roof 2b are driven into holes bored in advance around a tunnel. After that, the vertical pipe-roofs 2a and 2c are connected to an anchor 12 fixed to a reaction force coffer body with a bracket 11. A cutting edge and the coffer body are pulled by a hydraulic jack through a PC steel wire provided to a heading 14. At that time, towing capacity acted on the reaction force coffer body is transferred to the pipe-roofs 2a and 2c through the anchor 12 and bracket 11 and is also transferred to a bedrock. As a result, the circumferential. resistance force of the pipe-roofs 2a and 2c is used as reaction-force, and it becomes increased towing reaction force as a whole. According to the constitution, increased reaction force is obtained without providing a reaction force temporary wall, so that a coffer towed body is lengthened, and a structure crossing under a line can be economically constructed.
