Title: Production of filth treating bag
Inventor: NIITSUMA KINICHI
IPC: A47K11/06
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for a complicated process and to improve production efficiency by inserting water absorptive sheets into a housing bag and subjecting these sheets to point thermal compression bonding from both front and rear surfaces of the housing bag. SOLUTION: The water absorptive sheet 1 formed by coating the top and bottom of solidified paper with thermally soluble nonwoven fabrics is two-folded and the bent part 6 thereof is inserted to face downward into the inner bottom of the housing bag 2. In succession, the two-folded water absorptive sheets 1 are subjected to point thermal compression bonding from both front and rear surfaces of the housing bag 2 where the free end edges 13 of the water absorptive sheets 1 exist. The thermal compression bonding is executed at a proper temperature at which the two-folded water absorptive sheets 1 are not joined to each other.  When the compression bonding from both front and rear surfaces of the housing bag 2 to the part 3 to be thermally compression bonded completes, the two-folded water absorptive sheets 1 are not joined to each other and one of the free ends 12 thereof is joined to the part 3 to be thermally compression bonded on the rear surface side of the housing bag 2 and the other of the free ends 12 is joined to the part 3 to be thermally compression bonded on the front surface side of the housing bag 2, respectively, by which the desired filth treating bag is completed.

Filed: 1981-04-13
Abstract: PURPOSE:To form a speed detector of simplified circuits by separating the  output of a speed generator with a photocoupler, and using a comparator for an  oscillation circuit and a waveform shaping circuit. CONSTITUTION:While a speed generator is not in operation, a constant electric current flows through its winding TG to a light emitting diode Pd of a photocoupler PC, and a photodetecting transistor PT is on. Electricity is charged to a capacitor C; at the same time, the capacitor C is discharged periodically by a transistor Tr3 for electric discharging connected to the output terminal of a comparator COMP, and the comparator COMP makes oscillation motion. When the speed generator begins to revolve, the oscillation phenomenon is broken, and the comparator COMP changes over to a waveform shaping circuit which converts a sine wave input to a square wave output.

Filed: 1984-03-26
Abstract: PURPOSE:To decrease generation of fogging and to form a sharper recording image by adjusting the higher harmonic component of the oscillating electric field in a developing area thereby adjusting the developing characteristic. CONSTITUTION:The developing characteristic in a developing region A changes with a change in a time constant when the higher harmonic component of the socillating electric field in the region A is adjusted by changing over the time constant of a high frequency adjusting circuit 11 consisting of an R-C integration circuit.

There is thus no need for changing the amplitude, frequency or DC component of the oscillating component and therefore the power source circuit is made simpler and the possibility of fogging is decreased. The sharp recorded image having an excellent gradation characteristic is obtd.

Title: Production of liquid crystal display device
Inventor: TANAKA YASUO
IPC: G09F9/30
Filed: 1987-03-13
Abstract: PURPOSE:To prevent TFT from breakage due to deformation of glass fiber generated in a laminating stage of an upper plate on a lower plate of a liquid crystal display element by using a spacer material comprising glass fiber in a sealing material on a wiring area for taking out a terminal, and an elastic plastic spacer on a picture area for filling liquid crystals. CONSTITUTION:Spherical beads 26 comprising a plastic having high compressibility and high thermal deformability are used as spacers on a picture area 23 where a TFT element, cross-over wiring of scanning lines and signal lines are distributed, and glass fibers 25 are dispersed in a sealing material 24 for laminating an upper plate 21 to a lower plate 28 on an area 22 where an outgoing wiring is distributed, laminating thus the upper plate on the lower plate by applying thermal load. By this method, crushing of the TFT element by the pressure is prevented because of the deformation of the spherical plastic spacers after the application of thermal load due to its high compressibility and some thermal deformability when the spherical plastic spacers 26 dispersed on the picture area happen to come to the a-Si TFT element area.
