Title: Optical beat frequency measuring device
Inventor: ITO KAZUHIKO
IPC: G01J9/04
Filed: 1985-04-19
Abstract: PURPOSE:To simplify configuration of an electric circuit by frequency sweeping frequency of reference laser light for making optical heterodyne detection using a optical frequency modulator. CONSTITUTION:Laser light 2 emitted from a laser light source 1 is branched into two 2A, 2B by a light branching device 3. One of branched 3 laser light 2A is supplied to an optical path that constitutes an object to be measured. Another laser light 2B is fed to a optical frequency modulator 5. Assuming that frequency of laser light is fL, frequency deviation received by the object to be measured 4B is fX, and frequency to be modulated is fB, optical frequency passed through the object 4B becomes fL+fX, and frequency of modulated 5 signal goes to fL+fB. Accordingly, the output voltage of counted value of a counter 7B and a converter 7C can be taken in circuits 13, 14 by detecting signals when the signals are outputted from a band pass filter 11, then applied with waveform shaping and supplying them to a latch circuit 13 and an analog holding circuit 14. Further, it is possible to find frequency deviation fX received by the object 4B by finding the counted value or voltage value.

Title: Programmable controller for distributed control system
Inventor: NAKAJIMA KAZUYOSHI
IPC: G05B19/05
Filed: 1990-03-30
Abstract: PURPOSE:To always accurately recognize the maximum value of data link refresh cycle time by detecting the cycle time between plural programmable controllers(PCs), storing data relating to the maximum value of the cycle time, transferring the stored contents to a display means, and displaying the transferred contents. CONSTITUTION:Plural PCs are connected to a link signal line through a communication IF 35 and initialized at first. Then, whether a communication cycle has been completed or not is discriminated, and at time time of completing the cycle, whether the completion is the initial time or not is discriminated. When the discrimination is NO, a timer module 34 calculates the refresh cycle time (Rt) of a data link from a time difference between current time and the preceding communication cycle completion. Then whether the current value of the Rt is larger than the maximum value of the Rt stored in an internal RAM 32 or not is discriminated, and when the current value is larger, the maximum value data in the RAM 32 are updated. Then the current time is stored in the RAM 32 as the preceding communication cycle completion time and displayed on the screen of a CRT 54. Consequently, the maximum value of the data link Rt can be always accurately recognized without executing calculation or measurement.

Title: Hot water boiler
Inventor: TAKEDA SHINYA
IPC: F24H1/44
Filed: 1986-04-14
Abstract: PURPOSE:To increase the heat efficiency of the hot water boiler, to reduce the heat radiation loss at the time of stopping combustion and to fabricate the same in a compact structure. CONSTITUTION:An hot water boiler is provided at the lower part of a boiler body 11 with an exhaust air port 16. At this portion, that is, the lower part of the body 11, a heat exchanger 18 is provided. Even when hot air of an exhaust gas exhausted by passing between fins of the heat exchange 18 rises up, hot air is received by the body 11 positioned at the upper part thereof, and is heat-exchanged with hot water within a water chamber portion 13 around the outer periphery of the can body 11. Accordingly, the temperature of the body 11 does not rise up unlike one in which the temperature of hot water is increased by this much, and hot air is extracted as it is to the outer side. Further, at the time of stopping combustion, a natural draft is not produced between the opening of a burner 14 and an exhaust cylinder, and hence any heat radiation loss, on such a reason that hot water within the heat exchanger 18 and the water chamber 13 is cooled, is not caused, and further since the burner 14 does not penetrate through the water chamber 13, the structure of the hot water boiler is very simple.
