Title: 1,1-difluoroalkane derivative compound and liquid crystal composition containing the same
Inventor: SHINTANI SEIJI
IPC: C09K19/30
Filed: 1991-08-23
Abstract: PURPOSE:To provide a new 1,1-difluoroalkane derivative expected to give a liquid crystal composition having high response speed owing to low viscosity and high stability to light. CONSTITUTION:The compounds of formula I (A<1> to A<4> are trans-1,4-disubstituted cyclohexylene, 1,4-disubstituted phenylene, etc.; Y<1> and Y<2> are COO, OCO, CidenticalC, CH2CH2, CH=CH, OCH2, CH2O or single bond; m and n are 0 or 1; R<1> and R<2> are 1-10C alkyl, halogen, CN, etc.), e.g. the compound of formula II. The compound of formula (Y<1> and Y<2> are not CidenticalC) among the above compounds can be produced by reacting a compound of formula 7 with a compound of formula 8. Since the compound has low viscosity, it is effective to improve the response speed of a liquid crystal composition by the addition of only a small amount of the compound to enable the low-voltage driving, high-duty driving and the work over a wide temperature range. The durability to ultraviolet ray is also higher than a difluorostilbene-type compound to enable the full utilization of the characteristic feature of low viscosity.

Filed: 1987-09-24
Abstract: PURPOSE:To reduce defects in conduction between an upper-layer wiring part and a lower-part wiring part by forming two or more through holes for each connection part of the upper-layer wiring part and the lower-layer wiring part. CONSTITUTION:Wiring parts L1-L20 are composed of a first-layer aluminum wiring part AL1 and a second-layer aluminum wiring layer AL2 which has been connected to this aluminum wiring part AL1 via through holes TH. Two through holes TH are made at a connection part of the first-layer and the second-layer aluminum wiring parts AL1, AL2. The second-layer aluminum wiring part AL2 is connected to the first-layer aluminum wiring part AL1 via these two through holes TH. The through holes TH are made in an interlayer insulating film 3. The two through holes TH are formed at the connection part of the first-layer and the second-layer aluminum wiring parts AL1, AL2; accordingly, even when a deterioration in conduction is generated at either of the through holes TH, the conduction does not become defective as long as one through hole TH is conductive.

Title: Transfer material separating device for image forming device
Inventor: SHIBAYAMA AKIHIRO
IPC: G03G15/14
Filed: 1986-10-07
Abstract: PURPOSE:To prevent picture quality from deterioration such as transfer missing by providing a hygroscopic member to be reduced at its resistance by moisture adsorption in the vicinity of a destaticizing electrode opposed to an image carrier so as to be held between insulating members as a correcting electrode. CONSTITUTION:Since the upper end 3b of a transfer charger shield on the contact side of an insulating member 4b is covered with the insulating member 4b, a bias is effectively prevented from being leaked and the leading end of a separating device 4, i.e. the leading end of the destaticizing electrode 5, is easily positioned. The hygroscopic member 6 such as paper to be reduced at its resistance by moisture absorption is provided in the vicinity of the leading end of the electrode 5 and the member 6 is connected to a bias power supply 8. When the member 6 is reduced at its resistance under high moisture environment, the potential is boosted by voltage applied by the power supply 8 and the polarity of the member is the same as that of the electrode 5, so that discharge impedance is increased, discharge between a transfer material and the electrode 5 is suppressed, transferring charge can be prevented from being leaked and the deterioration of the picture quality due to the lacking of the intensity of an electric field at a transfer portion is prevented.

IPC: B41J13/00
Filed: 1984-11-13
Abstract: PURPOSE:To eliminate troublesomeness in setting a paper-supplying presusre according to the kind of a pepar, by setting a high paper-supplying pressure only when the leading end of an uppermost paper passes over a paper- distributing plate and keeping a low paper-supplying pressure at other times.

Title: Method to enhance effectiveness of plastic additive
Inventor: TSURUOKA MASAFUMI
IPC: C08K5/527
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a method for screening a functional agent effective with a small amount of use and an agent that carries the functional agent to the surface of a thermoplastic resin using a sodium 2,2-methylenbis(4,6-di-tert- butylphenyl) phosphate concurrently when the functional agent such as a germicide and an insecticide is blended to the thermoplastic resin. SOLUTION: Screening tests for agents to transfer a functional agent effectively to the surface of a plastic showed that using a sodium 2,2-methylenbis(4,6-di- tert-butylphenyl) phosphate concurrently is as effective, even if only a small amount is applied, as compared to using the functional agent singularly. This agent is an agent to make nuclei for a crystalline thermoplastic resin and is an additive having an effect to increase transparency and rigidity of a plastic. 0.05-5.0 wt.% of this agent on the basis of a plastic is added as it is or as a masterbatch. Optionally a scenting agent, a coloring agent, an anti-ultraviolet agent or the like is concurrently used. Various types of plasticizers can be used for its blend.
