Title: Image forming apparatus
Inventor: KIMURA SADAHISA
IPC: H02M7/06
Filed: 1995-09-20
Abstract: PROBLEM TO BE SOLVED: To provide an image forming apparatus which has enhanced a power efficiency and reducing a noise. SOLUTION: A power supply means is composed of a switching regulator 40 to supply DC power to a driver 44, a control means 42 for controlling this switching regulator 40, an operating means 46 and a sensor means 48. The control means 42 detects a voltage of the power induced on a secondary coil of the switching regulator 40 and controls selection of either one of the full-wave rectifying or voltage-doubler rectifying the AC power supply. With this control, when an output current of the switching regulator 40 is higher than the constant value, an active filter turns on and when an output current is lower than the constant value, the active filter turns off. Thereby, a harmonic current and an input current are lowered and higher efficiency and low noise can be realized.

Title: Buffer material for soundproof flooring and manufacture thereof
Inventor: ISOYAMA SHIGETAKA
IPC: B32B5/18
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To prevent water from seeping out of a floor surface and also prevent the floor surface from being impregnated with an adhesive by forming a thermoplastic resin layer with an adhesive function on a main face on the opposite side to a sheet, on a thin sheet, and forming a porous sheet on the thermoplastic resin layer. SOLUTION: A resin layer 2 composed e.g. of, a low melt point polyethylene resin as a thermoplastic resin is formed on one of the faces of a moistureproof paper 1 as a thin sheet. In addition, a soft polyurethane foam sheet 3 is formed as a porous sheet on the resin layer 2 and then is thermally compressed using a heating roll. Thus the surface of the resin layer 2 on the sheet 3 side is melted to form an adhesive layer 4 and at the same time, the main face of the resin layer 2 on the moistureproof paper 1 side is left as it is without melting it. Consequently, the bonding between the resin layer 2 and the soft polyurethane foam is reinforced with the adhesive layer 4 and at the same time, the resin layer 2 which remains unmelted gives a moistureproof effect. It is preferable that the soft polyurethane foam sheet 3 has about 18-65 kg/m3 density and about 2-10 mm thickness.
