Title: Optical path supervisory device
Inventor: HAMAZUMI YOSHIYUKI
IPC: H04B10/07
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To suppress the deterioration of a CN ratio of a pilot signal even when the number of wavelength of an optical signal which is inputted to a light space switch is increased by replacing M input converging devices with a pieces of (b) input converging devices and one (a) input converging device, branching a part of an output signal of the (b) input converging devices and supervising a pilot signal that is superimposed on the optical signal. SOLUTION: The functions of four input converging devices 31 and 32 are respectively divided into two input converging devices 31-1 to 31-3 and 32-1 to 32-3, and branching devices 41-1 to 42-2 are arranged before the devices 31-3 and 32-3. Optical signals which are outputted from 1×2 light switches 21 and 22 to an output port 61 are branched from an output of the device 31-1, and a pilot signal which is superimposed on the optical signal is supervised by a connection supervisory circuit 51-1. Similarly, optical signals are branched from the devices 31-2 to 32-2 and connection supervisory circuits 51-2 to 52-2 supervise pilot signals. With this, the wavelength multiple number of an optical signal that is a supervisory object becomes two wavelength at most and the deterioration of a CN ratio of a pilot signal can be suppressed.

Title: Sample & hold circuit
Inventor: KOTOBUKI KOKURIYOU
IPC: G11C27/02
Filed: 1994-08-08
Abstract: PURPOSE:To obtain a sample & hold circuit in which generation of refresh noise is prevented by providing a pair of sample & hold circuits and a multiplexer. CONSTITUTION:The sample & hold circuit comprises a first sample & hold circuit SH1, a second sample & hold circuit SH2, and a multiplexer MUX, wherein an input voltage Vin is fed to the first sample & hold circuit SH1. The second sample & hold circuit is fed with an output from the first sample & hold circuit SH1 and the multiplexer MUX selects the output from the first and second sample & hold circuits alternatively. Since the sample & hold circuit SH1 receives an output from the sample & hold circuit SH1, the input voltage Vin is taken in with a lag corresponding to a single sample & hold timing. The lag is used in the multiplexer MUX for outputting a data from the SH2 at the time of refreshing the hold circuit of the SH1 and a switching is made again to the output from the SH1 upon finishing the refresh thus eliminating the influence of refresh noise.

Title: Concrete composition
Inventor: CHIKAMATSU RYUICHI
IPC: C04B28/02
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent the separation of a mortar and a coarse aggregate by regulating a bulk density of the mortar obtained by removing the coarse aggregate from a composition comprising a cement, the coarse aggregate, a fine aggregate, water and various additives optionally added thereto so as to be the same as the density of the coarse aggregate. SOLUTION: The ratio of the bulk density of a mortar to the density of a coarse aggregate is preferably regulated so as to be 1.0-1.1, and the regulation is preferably carried out by regulating the density of the coarse aggregate, or regulating the density of the fine aggregate. The density difference between the mortar and the coarse aggregate is reduced by regulating the bulk density of the mortar so as to be nearly the same as the density of the coarse aggregate, and the separation of both of the mortar and the coarse aggregate is hardly caused even if the concrete composition is compacted while forcibly providing a vibrational energy thereto.  In the case of highly fluid concrete with imparted self-filling properties hardly requiring the compaction, the separation of both of the components is hardly caused even if the fluidizing distance becomes long, and the concrete composition is loaded in a homogeneous state.

Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To attain a high speed for multi-search channel selection by reducing a channel selection settling wait time required for the multi-search channel selection. SOLUTION: A microprocessor 10 gives a frequency division ratio (x) to a 1/x frequency divider 12 to lock a local oscillating frequency of a local oscillator 5 being a component of a PLL circuit control system so as to allow a tuner section 2 to tune sequentially pluralities of channels corresponding to channel position numbers. In this case, the microprocessor 10 discriminates a frequency difference between a selected current channel and a channel selected next as a difference between variable frequency division ratios and sets a channel selection settling wait time depending on the discrimination result. Since it is possible to minimize and vary the channel selection settling wait time having been a fixed time in conventional receivers, the total processing time of the multi-search channel selection is reduced so as to quicken the multi-search channel selection.
