Patent JP-H01177799-A (JP)
Title: Switching system
Inventor: OKAYASU MASAHARU
IPC: H04Q3/52
Filed: 1988-01-08
Abstract: PURPOSE:To suppress the speeding up of operation and to improve transmission efficiency by providing plural pieces of input reception circuit parts, output route determination circuit parts, output time slot determination circuit part, output selecting control memories, and selection circuit parts, etc. CONSTITUTION:When the input reception circuit part 10 and 11 receives at least the leading two bits of the header part of input data in zero or one i.e. either b/i or h2-h0, an output route for the data is determined by the output route determination circuit 20, 21. Thereafter, output selection information out of a bit-multiplexed input is written in the output selection control memories 50, 51 via the output time slot determination circuit parts 40, 41. And the selection circuit parts 60, 61, in case valid/invalid representation in the memories 50, 51 is in one, selects and outputs the data designated by the input route and the bit number. In case said representation in the memories 50, 51 is in zero, the circuits 60, 61 outputs data all in one as invalid data. As a result, excessive speeding up of operation at the time of selecting an output route and multiplexing more than necessary can be suppressed, hence the transmission can be achieved with an excellent efficiency.

Title: Thermoplastic synthetic resin tube and manufacture thereof
Inventor: SATO MASAO
IPC: B29C65/18
Filed: 1988-01-08
Abstract: PURPOSE:To eliminate the sealing defectiveness due to pin hole and flaw and ensure perfect sealing by a method wherein side sealed parts, which are produced by polymerization-thermowelding along both side folds of a thermoplastic synthetic resin tube main body, are provided. CONSTITUTION:A thermoplastic synthetic resin tube main body 1 is a cylindrical tube produced by blow-extruding, for example, polyethylene. Since side sealed parts 2 and 2 are produced by polymerization-thermowelding along both side folds, which are developed under the state that the tube main body 1 is folded flat, so as to weld the polymerized folded parts into integral structures, the strengths of the folded portions can be remarkably increased. The side sealed parts 2 and 2 can be produced with heater, by high frequency welding or the like. In addition, the side sealed parts can continuously be treated during the blow extrusion process of the thermoplastic synthetic resin tube main body 1. Further, the side sealed parts can independently be produced every time when necessary. By cutting the tube main body 1 in the desired length and, after that, similarly polymerization-thermowelding the upper and lower openings for sealing, various matters to be housed including vegetables and cereals can be housed in the tube.

Title: Floor heating apparatus
Inventor: MATSUMORI MASATO
IPC: F24D19/10
Filed: 1984-01-09
Abstract: PURPOSE:To shorten a rising time of a room temperature and to improve operability, by a method wherein a device is constituted such that, before a time at which the device is operated at a desired temperature, it is operated at an operation preparing set temperature, being lower than the desired temperature, for a given time. CONSTITUTION:At a bedtime, a timing device 2 is set to a time T at which a next heating is needed. This causes the timing device 2 to maintain an output J at a level H until a T-DELTAT time, being DELTAT earlier than a set time, elapses and apply a voltage Vr2, responding to a resistor 16, through turning ON of a transistor 3 to the inversion input terminal (-) of a comparator 9. This causes a radiator to perform operation preparing heating. When T-DELTAT time, to which the timing device 2 is set, elapsed, the output J is decreased to a level L, the transistor 3 is turned OFF, a voltage Vr, responding to a varying resistor 7, is applied to the inversion input terminal (-) of the comparator 9, and a desired temperature control takes place. This constitution enables speeding-up of a rise in a room temperature at a time at which heating is needed, and improvement of operability.
