Title: Flat grooved pipe and manufacture thereof
Inventor: OGAWA HIROHARU
IPC: F28F1/40
Filed: 1989-10-18
Abstract: PURPOSE:To drastically improve a heat transfer efficiency, by limiting the inter-inner peripheral face dimension in the short size direction of a flat grooved pipe, specifying the ratio to the inter-inner peripheral face dimension in the long size direction as well, approaching each side wall of the groove mutually according to its separation from the bottom wall and limiting the pitch between the grooves. CONSTITUTION:The dimension H between the inner peripheral faces in the short size direction of the section orthogonal with the axial line of the flat grooved pipe 1 that plural grooves A are formed on the inner peripheral face is formed in 1mm min.-5mm max. and also the ratio of the dimension W between the inner peripheral face in the long size direction to the above dimension between the inner peripheral faces in the short size direction is formed at >=3. Also, the grooves A are formed so as to approach mutually according to each side wall A2 which rises from the both side edges of the bottom wall A1 being separated from the bottom wall A1 and also the pitch between adjacent grooves A is formed in 0.25mm min. and 0.7mm max. The efficiency of heat transfer is therefore improved and also the forming is executed while holding a floating plug work pipe from the inside, so a flat grooved pipe of good flatness is obtainable even in the case of the breadth / length of the dimension between the inner peripheral faces being a large oblateness of >=3.

Title: Detecting apparatus of moving object
Inventor: YAMAUCHI KAZUMASA
IPC: G01S15/88
Filed: 1987-10-27
Abstract: PURPOSE:To detect a moving object with high precision, by a method wherein a reflected wave from the object in a monitored space, a Doppler signal is extracted therefrom, discrimination is made as to whether the frequency of a reception signal is higher or lower than that of a transmission signal, and the number of waves of the Doppler signal is added or subtracted. CONSTITUTION:A frequency discriminator circuit 6 outputs a signal of high level when the frequency of a reception signal is higher than that of a transmission signal, and outputs a signal of low level when the former is lower than the latter. Now, when an object goes away rapidly from the state of coming near at a point of a time t0, an output of the frequency discriminator circuit 6 changes from a high level to a low level. An arithmetic circuit 7 executes an addition sequentially at each point of zero cross of a Doppler signal when said output is of high level, while executing a subtraction when it turns to be of low level. When this result exceeds threshold values S and S' set beforehand, an alarm is given from a threshold circuit 8. In this way, the moving object can be detected surely irrespective of a moving speed of the object.

Title: Inspecting method for optical fiber coupler
Inventor: SENDA KAZUNORI
IPC: G02B6/28
Filed: 1986-11-17
Abstract: PURPOSE:To measure the wavelength characteristics of the degree of coupling of an optical fiber coupler in a short time by using a heat ray generated by heating an incidence-side optical fiber as a light source, branching it at a welding and elongation part, and measuring the intensity of projection light appearing on a projection side and inspecting the coupling rate. CONSTITUTION:The optical fiber is heated from its side face and then the optical fiber reaches certain constant temperature and considered to be a kind of black body to become a light source which has a spectrum based on the Planck's rule of thermal radiation. When the temperature of the optical fiber is sufficiently high, it becomes a light source which generates light in a wavelength range (0.6-1.6mum) used for optical fiber transmission. This light is propagated in the core part of the optical fiber coupler, branched at the welding and elongation part, and projected from core parts 3 and 4 in the end surfaces of the fibers 1 and 2. This method allows the heating length of the optical fiber to be set optionally long and the energy generated by the heating is found by using the Planck's expression and Wien's displacement law and proportional to the value obtained by raising the heating temperature to the 5th power, so light with high energy is made incident on the optical fiber. Consequently, the light can easily be made incident on the optical fiber as compared with a conventional inspecting method, the measurement time can be shortened, and the measurement accuracy is excellent.
