Title: Multiplex processing device
Inventor: SAKURAI BUICHI
IPC: G05B9/03
Filed: 1981-05-22
Abstract: PURPOSE:To reduce the difference at point of time of a pulse output, by inputting the same types and values of inputs used at the software of each digital device and making the operation processing periods among the digital devices coincident with each other as much as possible. CONSTITUTION:A multiplex processing section 11 controls a trigger angle by selecting one pulse. Each operating section 7 obtains a current input from a respective input section 6 and introduces current inputs of other digital devices via a photoelectric converter 13 and an optical cable 12. One signal out of three current inputs introduced is used for the operation at each section 7. The same value is used for each operation section for the operation. A clock 14 specifying the operation period of each digital device is synchronized with an external forced signal 21. It is required for the forced signal 21 to be generated suitably, and in this case, the signal is generated in synchronizing with the zero point of a voltage signal.

IPC: H04L25/49
Filed: 1978-06-24
Abstract: PURPOSE:To make it possible to carry on reception and decoding for a long time even by a deteriorated circuit by controlling the 180 deg. phase shift of a decision timing phase and the inversion of decoded data when the count contents of each constant decision timing signal become more than a fixed value. CONSTITUTION:Exclusive-OR circuit EXOR1 compares the code of a split phase signal at decision timing with a code one bit before it, and the comparison coincidence signals are counted by counters CNT1 and CNT2. Then, when the count countent of each constant decision timing signal or for each constant time becomes more than a fixed value, FF6 is made to start inversion operation by an overflow signal, thereby controlling the 180 deg. phase shifting of the decision timing phase and the inversion of decoded data. Consequently, reception and decoding of split phase code transmission can be carried on for a long time even in case of a deteriorated circuit.

Title: Floor heating device
Inventor: ARAKAWA JUNICHI
IPC: F24D3/16
Filed: 1990-03-27
Abstract: PURPOSE:To improve heat transfer efficiency by laying down a floor surface material via a heat-resisting adhesive on the upper side of a hot-water mat composed of a foamed resin board with built-in resin pipes to inhibit deformation of the floor surface material, thereby causing close adhesion between the hot-water mat and the back side of the floor material. CONSTITUTION:A floor surface material 3 is laid down through a heat-resisting adhesive 6 on the upper side of a hot-water mat 2 consisting of a foamed resin board with built-in resin pipes 1. The hot-water mat 2 is formed by containing resin pipes 1 inside a heat-insulating layer 2a of independent foamed polyethylene. The polyethylene resin is a low-polarity material of inferior adhesion, and aluminum foil is adhered to the surface of its adhesive side through melting adhesion to serve as an adhesion process layer 5. A thermal medium is flowed through the resin pipes 1 in such a manner that the surface temperature of the floor surface material 3 is maintained from 30 to 35 deg.C to give full play to the floor hating function. The aluminum foil in the adhesion process layer 5 increases the wettability of the adhesive 6 to the heat insulating layer 2a, strengthens adhesion between the heat insulating layer 2a and the floor surface material 3, and imparts heat dissipated from the resin pipes 1 uniformly over the entire surface of the floor surface material 3.
