Title: Fine stipple-like decorative laminate
Inventor: KUBOTA YOSHIKAZU
IPC: B44C5/04
Filed: 1991-07-31
Abstract: PURPOSE:To obtain a decorative laminate in which a finely stippled feeling is hardly deteriorated if its surface is worn and its design characteristics are kept for a long time. CONSTITUTION:In a decorative laminate provided with decorative paper, decorative paper containing a substance imparting a finely stippled feeling is used. The substance imparting a finely stippled feeling in use exhibits the fine stipple- like design characteristics by being contained in the decorative paper, and the finely stippled feeling is further increased when the decorative paper is processed to a decorative laminate. As such a substance, a pigment having an average particle diameter of 20-100mum and a colored fiber processed to powder having a maximum dimension of 5-400mum are exemplified. One or more of these substances are appropriately selected, depending on the purpose and the desired design characteristics. The pigment has a particle diameter larger than that of a pigment normally used for coating or the like. Because a fiber colored with a dye has a weakness in weatherability, a fiber which can be originally colored with a pigment is preferably used as the colored fiber. For example, an originally colored rayon is exemplified.

Title: Semiconductor integrated circuit
Inventor: SUGAWARA MICHINORI
IPC: H03F1/30
Filed: 1991-08-27
Abstract: PURPOSE:To reduce the independency of a power supply voltage and the temperature of the output potential of a power supply circuit incorporated in the semiconductor integrated circuit less than the conventional one. CONSTITUTION:An output potential generation part 1 is composed of the serial connection of resistance R<1> and transistors Q<1> and Q<2> between a high-order power supply terminal 3 and a low-order power supply terminal 4. Current IR flowing the output potential generation part 1 is shunted by a bypass circuit 6. The base potential of a transistor QA of the bypass circuit 6 provides the electric potential of the split point obtained by splitting the power supply voltage V by resistance Rc and R13, and the current IR and the current IA have the same positive independency on the power supply voltage and on the temperature. The current II is the one where the current IA is subtracted from the current IR, resulting in the only little change because of the mutual cancellation of the two current change even when the power supply voltage and temperature are changed.
