Title: Manufacture of color filter
Inventor: SUZUKI YOJI
IPC: G02B5/20
Filed: 1992-01-14
Abstract: PURPOSE:To make a picture element pattern flat so as to reduce nonuniformity of color distribution in the picture element by making the width of a pattern of a form plate used for printing one within a specific range of a picture element width of a corresponding color filter. CONSTITUTION:After a black matrix 21 is formed on a washed transparent substrate 20 by a printing method, it is heat-treated by using a hot air circulating oven. Next the picture element pattern 22 of the color filter is printed in such a manner that a pattern width of the form plate used for the printing is made to 40-60% of the picture element width of the corresponding color filter and overprinting of 10-20 times is executed. Also after the overprinting of one color is completed, heat-treatment for hardening is conducted. Thus an upper part of the pattern is widened, so the difference of the film thickness between an edge of the pattern and the central part becomes small and the flat part in the crosssectional from becomes wider, therefore the nonuniformity of color distribution in the picture element decreases.

Title: Measuring method for cluster size of water by inter atomic force microscope
Inventor: TAKAZAWA NOBUAKI
IPC: G01N37/00
Filed: 1999-01-12
Abstract: PROBLEM TO BE SOLVED: To provide a measuring method in which a cluster size can be evaluated with high accuracy and simply by a method wherein the height of a leaching solution bubble is measured under an inter atomic force microscope(AFM) and the cluster size is found by referring to the map of a relationship between the height and an average cluster size. SOLUTION: For example, hexane as a hydrophobic substance 3 is adsorbed to a porous materiel 1 in the form of vapor under a high pressure, and the substance is immersed in test water 2. Then, hydrophobic vapor is leached in a liquid as the hydrophobic substance 3. At this time, a cohesion is small in small cluster water 4 whose molecular weight is small, and the hydrophobic substance 3 becomes large. On the other hand, the cohesive force is large in large cluster water 5 whose molecular weight is large, and the hydrophobic substance 3 becomes small. Then, the size of the hydrophobic substance 3 is measured in such a way that an AFM probe 6 is scanned in the test water 2 and that a repulsive force which acts from the uneven part on the surface of an inter atomic force is converted into an image.  As a result, it is found out that a small cluster size is at 1 to 2 nm and that a large cluster size is at 3 to 4 nm.

Title: Intermediate transfer body
Inventor: FUJIWARA TOSHIMITSU
IPC: G03G15/10
Filed: 1994-01-21
Abstract: PURPOSE:To make transfer property on an intermediate transfer body excellent and to improve transfer efficiency on a recording body and the degree of freedom for selecting a material by providing the intermediate transfer body with an electrically conductive supporting body and a surface layer having specified water absorption coefficient. CONSTITUTION:The intermediate transfer body 8 is constituted of the electrical conductive supporting body and the surface layer. Then, the surface layer whose water absorption coefficient is 0.15-10.0% is used. By adjusting the water absorption coefficient of the surface layer within such a range, the transfer body 8 constituted so that both of a first transfer action and a second transfer action are excellently executed thereon and the transfer efficiency is high is obtained. When the water absorption coefficient of the surface layer is smaller than 0.15%, excellent releasing property obtained because water content sufficiently intervenes between toner grains and the transfer body 8 is not obtained at the time of the second transfer action. When it is larger than 10.0%, a so-called image flowing phenomenon is easily caused at a developing time because the excessive water content is transferred to an image carrier 1 such as a photoreceptor from the transfer body 8 at the time of the first transfer action.

Abstract: PURPOSE:To vary the threshold value by putting a resistance between the drain of a field effect transistor on the last stage and an output part of the last stage. CONSTITUTION:An n channel MOSFETTr2 and a p channel MOSFETTr1 are turned off and an respectively when the output Vout of a Schmitt trigger circuit is set at a low level (0), i.e., the input Vin is set at a high level (1). Under such conditions, the input Vin is slowly changed to a lower level and set at a level equal to VthL obtained from an equation 5-b. Thus an inverter 1 is inverted to 1 from 0, and the Tr1 is turned off at and after this instant. While the Tr2 is turned on, and the logical threshold voltage of the Schmitt trigger circuit is set equal to VthH obtained from an equation 5-a. When the input Vin changes gradually to a high level from 0, no state change is generated at the Vth or below. When the Vin is equal to the VthH, the inverter 1 is inverted to 0 from 1 Thus the Tr1 and Tr2 are turned on and off, respectively, and the logical threshold voltage is set at VthL at this instant.
