Title: Image reader
Inventor: YAMANAKA TOSHIHISA
IPC: H04N1/028
Filed: 2000-11-06
Abstract: PROBLEM TO BE SOLVED: To provide an image reader that prevents production of noise involved in employing a high frequency drive signal used for a photoelectric conversion means and drives the photoelectric conversion means at high speed. SOLUTION: A CCD driver 9 receiving a reference clock from a clock output means uses a phase signal length control means to generate a plurality of CCD drive signals whose phase and signal length are controlled. A noise countermeasure means to unsharpen leading and trailing of the generated drive signals is interposed to an output of the CCD driver. Thus, characteristic dispersion or the like of the noise countermeasure means can be absorbed even when the phase difference between the drive signals is small and the CCD operating period can be decreased by the share in comparison with the case that the drive signals are generated at an input side of the CCD driver and they are outputted from the CCD driver as they are.

Title: Bottom-gate thin-film transistor and its manufacturing method
Inventor: ODA NOBUHIKO
IPC: H01L29/04
Filed: 2000-11-07
Abstract: PROBLEM TO BE SOLVED: To solve the problem that a back channel phenomenon is generated by impurities injected into an injection stopper 55 when ion implantation is made with the injection stopper 55 as a mask, and variation in manufacturing a bottom-gate thin-film transistor is caused.

Title: Slidable coverture for snow/ice having translucency
Inventor: YASUI KATSUMI
IPC: C09D183/04
Filed: 2000-12-07
Abstract: PROBLEM TO BE SOLVED: To provide slidable coverture for snow/ice which has a high joining property and durability, makes adhered snow/ice slide off quickly, and suppresses the adhesion of snow/ice by making a period of time for the adhesion of snow/ice as short as possible, by an inexpensive and simple method. SOLUTION: The joining property is increased by inserting an inorganic type base film on the lower layer of this coverture. At the same time, the wetting property between the coverture and water is set to be 70 deg. or higher by a contact angle, and the water sliding angle of a water drop is set to be approximate 40 deg. or lower as the water sliding property. Thus, when snow/ice is adhered, the snow/ice adhered on the external surface of an article to be covered can be quickly made to slide down by the snow/ice sliding property of the external surface of the coverture. Also, the joining property at a particle lever with the coverture having the snow/ice sliding property can be increased by inserting the inorganic type base film which is formed of a silicone resin. Thus, the coverture having a high joining property and durability can be formed.  Also, the inorganic type base film formed of the silicon resin is extremely thin, and does not obstruct the transmission of light, and the translucency is not spoiled.
