Title: Functional sunshade
Inventor: NAKAJIMA TOSHIMITSU
IPC: B60J3/00
Filed: 1998-09-10
Abstract: PROBLEM TO BE SOLVED: To suppress a temperature rise in a compartment due to sunlight, to deodorize the compartment by ultraviolet rays from the sun, and to increase adhesiveness and durability by arranging a photocatalyst layer in the vehicle interior via an intermediate layer at least. SOLUTION: In formation of an upper liner, a photocatalyst layer 4 and a liner 2 serving as an upper face are stuck to each other via an intermediate layer 5 by means of a laminator. Then, a middle core 3 is arranged between the upper liner and a liner 2 serving as a lower face. As a photocatalyst, titanium oxide is most preferable and used profitably because of its structure stability, photoreaction harmful substance removing ability, and handling safety. A functional sunshade 1 with the photocatalyst layer arranged by mainly using a corrugated fiberboard material activates the photocatalyst layer by using ultraviolet rays from the sun and promotes an oxidizing reaction so as to transform an odorous substance into a non-odorous substance.  In this way, the air inside the vehicle interior can be purified automatically when the sunshade 1 is used for suppressing a temperature rise due to solar radiation.

IPC: G01N15/14
Filed: 1988-10-12
Abstract: PURPOSE:To make it possible to measure the concentration of fine grains correctly by measuring the number and the concentration of the fine grains in liquid from a concentration signal. CONSTITUTION:Liquid to be measured 4 incorporating fine grains used in a plant 3 is guided into a detected signal output part 5 through an upstream side pipe line 2. A detected signal 5a is outputted from said output part 5. The signal 5a is inputted into a flow-rate operating part 23. A specified operation is performed for pulses 5a1 included in the signal 5a in synchronization with the counting operation in a concentration-signal outputting part 9 during the period equal to a counting time. A flow rate signal 23a corresponding to an instantaneous flow rate F of the liquid 4 is outputted. Then, the flow of the liquid 4 undergoes feedback control in a flow rate control part 24 so that the flow rate F of the liquid 4 attains a specified preset value Fs. Therefore, bubbles do not stay in a flow rate control valve 26. The instantaneous flow rate of the liquid 4 can be made to be a constant flow rate. The fluctuation of the flow rate caused by the stagnation of the bubbles does not occur. The concentration of the fine grain 11 can be measured accurately with a concentration signal 9a.

Such a display of the form is defined as a three-dimensional run length display. The data consisting of the distance (depth value) between the lattice point and the form and the color data is defined as the picture data. Thus the three-dimensional basic form data on a rectangular parallelepiped, a column, a cone, a globe, etc. are stored in an element buffer 23 and then converted into the three-dimensional run length data by a graphic processor 21. This data is converted into the picture data and sent to a graphic display device for display through a communication interface 22.
