Title: Luminaire light control body and luminaire using this
Inventor: ICHIKAWA ATSUJI
IPC: F21S4/00
Filed: 1996-08-07
Abstract: PROBLEM TO BE SOLVED: To provide a luminaire light control body (reflection plate) in which moisture resistance can be improved though it is made of paper, and to prevent spreading fire even when an electrical component equipped with luminaire catches fire. SOLUTION: Coating layers made of high molecular substance or coating layers 34 and 35 containing this substance as a binder are respectively provided on both sides of a base paper 33 having a one-layer structure using paper as base material. A processed paper 31 is employed so that the coating layer 34 functions as a reflective surface to be positioned at least on one side to control light. This prevents the base paper 33 from absorbing moisture from a unreflective surface in the coating layer 35, which is more fireproof than paper and is attached to the unreflective surface of a reflection plate. Moreover, this prevents fire from directly spreading over the unreflective surface of the base paper 33.

Patent JP-H0872274-A (JP)
Title: Color thermal printer
Inventor: MIYAZAKI NOBUO
IPC: B41M5/34
Filed: 1994-09-02
Abstract: PURPOSE: To prevent a misregistration due to the difference of strains of a platen drum and a platen roller and the occurrence of a print unevenness due to the load change of conveying a color thermal recording sheet. CONSTITUTION: A color thermal recording sheet 10 is varied at a frictional coefficient according to a temperature, the coefficient becomes yellow thermal recording time > magenta thermal recording time > cyan recording time. Pressure contact forces of thermal heads 26-28 are set to yellow thermal head < magenta thermal head < cyan thermal head to match them, and the frictional forces between the heads 26-28 and the recording sheet 10 are substantially equal. Thus, since the distortion amounts of the drum due to the heads become substantially equal, no deviation of registrations occur. Since the loads of the heads become substantially the same, the feeding unevenness due to the load change is prevented, thereby eliminating density unevenness.
