Title: Distribution line carrier equipment
Inventor: SUZAWA SHUNJI
IPC: H04B3/54
Filed: 1991-04-05
Abstract: PURPOSE:To surely receive a signal without effect of resonance or the like by providing a means selecting a carrier frequency of a polling signal to a master station when no reply signal is received and providing plural reception circuits to a slave station. CONSTITUTION:A central processing circuit 55A sets a limit of a transmission repetitive variable (i) and a carrier frequency switching variable (k), increments the variable (i), sends a polling signal P whose frequency is (f) to discriminate the presence of a reply signal R from a slave station. When the signal R is not received, the transmission is repeated within a limit of the variable (i) and when the signal is not further received, other frequency is selected and the transmission is repeated within a limit of the variable (k) and the operation above is repeated by incrementing the variables k, i. When the reply signal is not sent in this way, the master station repeats the transmission while using other carrier frequency to avoid the effect of resonance thereby receiving the reply signal surely.

Abstract: PROBLEM TO BE SOLVED: To protect a worker surely against exposure to laser light by controlling an exposure preventing part to shut off or attenuate a laser light radiated from a laser generating section when a decision is made that a human body is possibly present in a space. SOLUTION: A decision is made by a controller 2 that a human body is possibly present in a protective housing 1 and subjected to exposure of laser light when presence of a human body is detected by a human body sensor 3, and a controller 3 controls a shutter drive circuit 4 to close a shutter 5 forcibly thus shutting off the emission opening of a laser 6. The shutter drive circuit 4 is locked until a state where a door 7 and a panel 10 are entirely closed is detected by a door open/close sensor 8 and a panel open/close sensor 9 and a state where a person is not present in the protective housing 1 is detected by the human body sensor 3 thus preventing radiation of laser light. This arrangement can protect a worker surely against exposure to laser light.

Title: Method and device for detecting object installed in shielded location
IPC: G01S7/292
Filed: 1992-03-30
Abstract: PURPOSE:To easily and accurately identify an object installed in a shielded location and detect the position of the object by radiating electromagnetic waves along the shielded location and forming the original picture of the cross section of the shielded location based on the time lag between the radiated electromagnetic waves and reflected waves from the object. CONSTITUTION:Electromagnetic waves radiated from a transmission antenna 3 advance in soil 1 and are reflected by, for example, part of a pipe 2 near the top 2a of the pipe 2. A reception antenna 7 receives the reflected waves and sends its output to a reception circuit 8. The time lag from the radiation of the electromagnetic waves from the antenna 3 to the reception of the waves by means of the antenna 7 corresponds to the distance from the surface of the soil 1 to the pipe 2. Therefore, when the antennas 3 and 7 are fixed in one body and moved across the pipe 2 buried underground on the surface of the soil 1, the cross section of the soil 1 including the pipe 2 can be detected.
