Title: Circuit switching system
Inventor: YAMADA MAMORU
IPC: H04J1/00
Filed: 1984-01-26
Abstract: PURPOSE:To facilitate the easy automatic switching of a circuit by providing a pilot circuit between a working station and a spare station and a main station and a switching station resepectively from the main station via the switching station and detecting the cut-off of a pilot signal due to a fault of the working station. CONSTITUTION:A main station 1, a switching station 2 and a working station 4 are connected by circuits L1-L3. A descending pilot signal P1 is oscillated 12 at the station 1 and detected by a coupler 33 of the station 3 via a switch 27 of the station 2. While ascending pilot signal P1 is oscillated 32 at the station 32 and detected by a coupler 13 of the station 1. In this case, a spare circuit L3 outputs the descending pilot signal P1 from an oscillator 22'' of the station 2, and this signal P1 is detected by the coupler of the station 3. While the ascending pilot signal P1 is transmitted from an oscillator 42 and detected by a coupler 23''. While the circuit L1 sends a pilot signal P2 of another frequency to a coupler 23 from an oscillator 12a and to the coupler 13 from an oscillator 22a and monitors them. When the circuit L2 is disconnected, a switch 2 is driven by the setection of a coupler 23' to secure connection between circuit L1 and L3. Thus the switching is facilitated with use of the pilot signals.

Filed: 1983-01-28
Abstract: PURPOSE:To perform accurate measurement, by obtaining the ratio of noises, which are measured when a light point is generated and when it disappears, and removing the noises from the output of a first light receiving means for obtaining the distance to the light point. CONSTITUTION:The image of light from a light point P is formed on the light receiving surface of a sensor 7. Its output is converted into a numerical value by an A/D converter 8, and the result is inputted to a computer CO. The inputted data is expressed by (St+Nt)n. At the same time, the output from a photodiode 10 is inputted as NMt through an A/D converter 11. The output NMt+Ts from the A/D converter 11 when the time Ts has elapsed is inputted and memorized. At the same time, the output from the image sensor 7 is inputted and (Nt+Ts)n is memorized. Then, NMt+Ts/NMt(St+Nt)n-(Nt+Ts)n is operated, and the data related to the intensity of the light at each (n) when the noises are approximately removed, is obtained.

Title: Surface defect inspection device
Inventor: NAKAYAMA OSAMU
IPC: G01N21/89
Filed: 1997-01-09
Abstract: PROBLEM TO BE SOLVED: To accurately detect various kinds of defects which occur on the surface of an object to be inspected. SOLUTION: A marking device 1 puts two reference coordinate marks 9 on the surface of an object 7 to be inspected in the width direction. CCD cameras 3 and 4 respectively pick up the image of the surface of the object 7 from the upstream and downstream sides while the surface is irradiated with light from a light emitting section 2. A signal processing section 5 executes coordinate correction on the image data picked up by means of the CCD cameras 3 and 4 which are installed to different locations at different angles based on the positions of the marks 9, forms synthesized image data from both coordinated- corrected image data by computing the difference between both data, and discriminates the presence/absence of a defect from the formed synthesized image data.

Title: Diversity device
Inventor: KUWABARA MIKIO
IPC: H04B7/08
Filed: 1994-02-07
Abstract: PURPOSE:To improve the gain of an antenna by reducing power which is to be consumed by the matching impedance connected with an unselected antenna and can not be utilized in the antenna switching diversity in a portable radio terminal. CONSTITUTION:A microstrip line 50 is connected from the terminals of antennas 40 and 41 which are physically apart via switching means 1 and 11. Each of the 21 and 31 parts of the microstrip line 50 becomes the electric length of a carrier frequency and a half-wave length and becomes an open stub of impedance infinity at the time of non-selection. From the joint point of microstrip lines 21 and 31, a microstrip line extending to a transmitter/receiver 51 comes out. This becomes equivalent to the connection of a selection antenna and the transmitter/receiver 51 through the microstrip line 50 and the loss by an unselected antenna can be prevented.

Title: Speed reducer using rolling planetary mechanism
Inventor: TOKUNAGA YOSHINORI
IPC: F16H13/08
Filed: 1987-01-23
Abstract: PURPOSE:To realize a rolling planetary mechanism having a high output and a long lifetime because of abrasion-resistant rolling surfaces, by composing the respective surfaces of rolling bodies, through which power is transmitted each other, of flat parts having a relatively small roughness and valley parts having a relatively large roughness. CONSTITUTION:In the part A between an input shaft 1 and planetary rollers 2, and in the part B between planetary roller 2 and an outer ring 5, while power is transmitted by the pressedly contacting force acting on respective rolling parts and the dragging force due to the viscosity of intervening lubricating oil, if both rolling surfaces being in contact with each other are composed of flat parts having relatively small roughness and valley parts having a relatively large roughness, a large frictional force can be obtained by the influence of the part having a large roughness to enable a high output to be achieved, and further a good contacting condition can be obtained because the valley parts act as oil grooves. Furthermore, the crest parts of surface roughness constitute flat parts having a relatively small roughness, so that the abrasion quantity to be produced can be restrained. Thus, the attainment of a high output and a long lifetime can be enabled.

Abstract: PURPOSE:To tune the rotating operation of a main motor with that of an optical motor by detecting the rotating speed of the motor, calculating the detected rotating speed data, and applying a reference clock in response to the result to a PLL circuit. CONSTITUTION:A rotation detector 17 samples the rotating speed of a rotating main motor M1 in the prescribed time width to detect the speed at every sampling to convert it to digital data, and outputs to a processor 18. The processor 18 takes a moving average, and applies a pulse corresponding to the average as a reference clock to a PLL circuit 19. The PLL circuit 19 outputs a pulse in response to the input clock to drive an optical motor M2. Thus, the rotating operation of the motor M1 can be turned with that of the motor M2.

Abstract: PURPOSE:To decrease the loss and heat generation of an apparatus by detecting the junction temperature of a GTO thyristor and, when said temperature is high, by decreasing the value of a normally ON-state current as compared with the case at the time of a low junction temperature. CONSTITUTION:In a gate-driving circuit supplying a GTO thyristor 3 with a steady ON-state current, a signal generator 4 generates a signal for maintaining the ON state of said GTO 3 and is insulated by a photocoupler 31 provided in a signal processor 30 to turn ON a transistor(Tr) 11 via FET 12 provided in a first gate current feeder 10. Then, the steady ON-state current is caused to flow through said Tr 11 from a DC power source 2 to the gate electrode of the GTO 3 via a resistance 13. In this case, a temperature sensor 5 is fitted to a cooling body fitted with said GTO 3 to detect the junction temperature of the GTO 3. When said temperature is higher than a specified value, the heat generation, loss and the like of the gate-driving circuit can be decreased by the reduction of a gate current.
