Filed: 1992-12-02
Abstract: PURPOSE:To reduce the size of a waste water tank and a waste water pump to decrease the power consumption and noise by forcing at least one tool to operate a waste water flow control means for controlling the waste water flow, thereby controlling the waste water flow of a drainage pipe less than a designated flow. CONSTITUTION:A control circuit 38 controls a sink 20, a tea server 23, a waste water flow control means of a dish washer 24, water level sensors 36, 37 and a waste water pump 27. A waste water signal from the waste water flow control means is checked by the control circuit 38. The tools are combined so that the waste water flow of the tool which gives a waste water signal does not exceed a designated flow, and a drain enabling signal is sent to the tool which corresponds to the combination. The tool which receives a drain enabling signal from the control circuit 38 conducts the drainage operation. Accordingly, even if the drainage operation of each tool overlaps, the waste water flow does not exceed a designated flow, so that the waste water tank and the waste water pump can be reduced in size.

Title: Information recording medium
Inventor: NAKANE YASUAKI
IPC: G11B7/24035
Filed: 1991-12-06
Abstract: PURPOSE:To improve a recording sensitivity by making a light absorption function and a foaming function to be performed by the same layer. CONSTITUTION:A light absorption layer 12 consisting of, for example, a thermoplastic resin layer contg. a light absorbent, such as org. dye or dye absorbing a recording laser beam, and a foaming material, a light reflection layer 13 having a high reflectivity to the laser beam and if necessary, a protective layer 14 for protecting the later 13 are provided on a base body 11 having light transmittability to recording and reading out light; for example, laser beams. Since the light absorption function and foaming function are performed by the same layer 12, the light is efficiently converted to heat by the light absorbent and the heat is efficiently transmitted to the foaming agent to foam this agent at the time of recording and, therefore, the high-density recording is executed. Since the layer 12 itself foams and expands to form pits 15, voids are not generated under the layer 13 and the mechanical strength of the pit parts increases. The layer 13 is locally lifted by the expansion of the layer 12 and the pits 15 are surely formed. The high-sensitivity recording is executed in such a manner.

Title: Atm line signal generating method and atm line signal processing unit using the method
Inventor: SHINKAI YOTARO
IPC: H04N19/60
Filed: 1994-12-27
Abstract: PURPOSE: To accommodate a digital video signal in an ATM line efficiently. CONSTITUTION: In the case of sending a 525/60 system Di type digital video signal (270Mbps), compression processing is applied only to a video signal component in an active are among digital video signals and various control signals are added to the processed component and the result is sent through an ATM 2 line. Figure A indicates configuration of frame signals per ATM 1 line. Compression processing (rounding processing of 10 bit data into 8-bit data) is applied to the video signal component and byte configuration of ATM cells is in matching with that of signal components other than the video signal by (10 to 8) bit conversion. Figure B depicts cell processing of the components above. When a total cell number is re-configured by an AAL5 layer, a signal of one frame is sent by 10-stages of CPCS sub layers as shown in figure C.  Thus, D1 type digital video signal is sent by using two ATM lines.
