Title: Measurement for size distribution of rain particle
Inventor: OTAKI HIDENARI
IPC: G01N15/06
Filed: 1986-04-14
Abstract: PURPOSE:To measure the particle size distribution of rain drops handily, by reading the diameter of water drops on a filter paper as trapped with the filter paper impregnated with an aniline blue powder placed in a rain to be measured to compute the results using a specified formula. CONSTITUTION:Water with the volume V previously measured is dripped on a filter paper impregnated with an aniline blue powder to form circular blue marks. Then, the relationship is determined between the diameter D of the circle and the volume V of water and furthermore, the relationship is obtained between phi and D by V=(pi/6)phi<3>. The filter is placed in a rain to be measured to trap as many water drops as possible as far as the diameter of the circle turned blue can be read. Then, the diameter of water drops is read on the filter paper and the particle diameter distribution of the rain contained per unit volume is determined by the formula [wherein Nphi' is the number of water drops per cubic meter with the diameter Dphi of the circular mark left on the filter paper, H rainfall (m/time), W total amount of rain trapped on filter paper and vphi dropping speed of rain with the particle size phi].

Title: Device for deciding strength of electric field
Inventor: HORIIKE YOSHIO
IPC: H04B17/318
Filed: 1984-04-26
Abstract: PURPOSE:To reduce number of components by allowing a frequency analyzer to extract a desired signal, taking a ratio with other noise frequency component and deciding the stregth of an electric fied so as to attain the use of a microcomputer. CONSTITUTION:The frequency analyzer 13 decomposes an input signal into 16 kinds of frequencies (f0-f15), a comparator 14 compares the frequency component, a component of the maximum amplitude is produced to an output (a) and the remaining components are produced to an output (b), which is fed to an adder 15. That is, when an input signal shown in Fig. (b) exists, an f9 is produced at the output (a), the remaining frequencies are produced to the output (b), they are added by the adder circuit 15, and an amplitude A is outputted. A deciding circuit 16 compares and discriminates the amplitude of the signal f9 and the output A and the ratio of the amplitudes controls an LED drive circuit 9. Thus, when the strength of electric field is very strong, the ratio of the signal f9 and A is large, LEDs of the circuit 9 are all lighted, and when the electric field strength is weak, the number of lighted LEDs is decreased. On the other hand, the signal f9 is fed to an information decoding circuit via a gate circuit 17 only when a signal from the deciding circuit 6 exists.

Title: Optical liquid level detection
Inventor: ASAKAWA KIYOSHI
IPC: G01F23/28
Filed: 1978-07-12
Abstract: PURPOSE:To highly accurately measure the displacement of a liquid level by detecting the existence of a transmission light which has transmitted through an optical waveguide. CONSTITUTION:There are buried in a substrate 11 of low refractive index a plurality of integrated optical waveguide arrangements 31 to 35 under the condition in which their one side is in contact with a gas phase 39 or a liquid phase 40. Integrated light source arrangements 21 to 25 connected with an electric input terminal 36 are attached to one end of the waveguide arrangements 31 to 35, and integrated optical detecting arrangements 26 to 30 connected with an electric output terminal 37 are attached to the other end of the same. Thus, if the optical waveguide arrangements 31 to 33 and 34, 35 are disposed above and below the liquid level 38, the lights from the sources 21 to 23 are allowed to transmit without any attenuation through the waveguide arrangements 31 to 33 until they reach the detectors 26 to 28 so that optical output can be taken out of the output terminal 37. However, the lights from the sources 24 and 25 are abruptly attenuated to fail to reach the detectors 29 and 30. As result, the fine displacement of the liquid level can be highly accurately measured even under bad circumstances by judging the existence of the optical outputs of the detectors 26 to 30.

Abstract: PURPOSE:To maintain a mixture ratio in stable at all times by a method wherein the sudden or unsteady operation of the plate valve is prevented in the damper for the variable Venturi tube carburettor. CONSTITUTION:A damper plate 32 is secured to a plate valve shaft 6 and a damper chamber 34, having an inner wall not contacting with the damper plate 32, is provided, while the damper device is constituted so as to have a small leaking area between the damper plate 32 and the damper chamber 34 and to work a vacuum between the plate valve and a throttle valve upon the damper plate 32 through a vacuum path 36. Now, when the throttle valve is opened suddenly, the plate valve 7f is tried to be opened instantaneously, however, the vacuum working on the plate valve is being introduced to one surface 33 of the damper plate 32, therefore, a force trying to close the plate valve is working upon the damper plate 32 and thus a closing torque is produced. This closing torque opens the plate valve slowly and accordingly the mixture will never becomes too much poor.

SOLUTION: In the case of stripping a strippable coating film formed on an automobile of which coating is completed and on which the strippable coating film is formed so as to retain the coating film appearance obtained at the time of coating, when the surface temperature of the coating is lower than 15 deg.C, warm water or steam at a prescribed temperature is sprayed to the coating film to heat the film and adjust the coating film surface at 15-35 deg.C and then the coating film is stripped out of the material. At the time when the surface temperature of the coating film is higher than 35 deg.C, cold water or steam at a prescribed temperature is sprayed to the film to cool and adjust its surface temperature at 15-35 deg.C and then it is stripped. In this case, since the strippable film has proper hardness and softness, the film can easily be stripped.

Title: Detection of welding end
Inventor: KANJIYOU YOSHIHIRO
IPC: B23K9/127
Filed: 1986-04-16
Abstract: PURPOSE:To exactly treat a welding end and to shorten the time for treatment by attaching sensors which detect a torch direction and welding progression direction to the front part of a welding torch and combining the signals from both sensors to detect the welding end. CONSTITUTION:Small bone members 2, 3 are welded by means of a wire delivered from the torch 4 while a weld line is detected by the sensor 5 at the time of vertically welding said members to a plane member 1. The welding end can be regarded as the corner where the members 2, 3 intersect when the sensor 6 detects the member 3 and therefore, an arc is ended at this point of the time. The end point of welding is regarded to be the corner where the angle between the members 2 and 3 is large when the sensor 5 detects the corner part in the non-operating state of the sensor 6. Welding is executed only for the time until the torch 4 arrives at the intersected point of the members 2, 3 after the detection by the sensor 5, then the arc is stopped. The torch 4 executes boxing of the end upon operation of the sensor 5 when the sensor 5 finally detects the member end in the non-operating state of the sensor 6. The welding is thus ended.
