Title: Ketone type ferroelectric liquid crystal compound and chiral smectic liquid crystal composition using the same
Inventor: FUKUSHIMA YUKIHIRO
IPC: G02F1/13
Filed: 1992-04-14
Abstract: PURPOSE:To obtain the subject compound, composed of a specific ketone group-containing polyphenylene compound, having great spontaneous polarization and capable of providing a chiral smectic liquid crystal composition such as an optical switch or an optical shutter having operation display of high image quality and high-speed responsiveness. CONSTITUTION:p-Bromophenol is acetylated and converted into a trialkyltin derivative, which is then made to react with a carboxylic acid chloride to deprotect the hydroxyl group. The resultant compound is subsequently converted into a trifluoromethanesulfonic acid ester. Thereby, a compound expressed by formula I (R1* is 4-20C optically active group) is obtained. On the other hand, the amino group in 4-aminosalicylic acid is iodinated and esterified with an optically active alcohol. The obtained ester is subjected to coupling reaction with p- bromophenylboric acid and then allowed to react with a trialkyltin compound to afford a compound of formula II [R3* is the same kind as that of R1*; (n) is 0-2; R is alkyl]. The resultant compound is made to react with the compound of formula I to provide the objective ketone type ferroelectric liquid crystal compound expressed by formula III. Furthermore, the objective chiral smectic liquid crystal composition is obtained by adding >=1mol% compound of formula III to other liquid crystal compounds capable of exhibiting the chiral smectic C phase.

Title: Lead-acid battery
Inventor: ASHIDA KATSUJI
IPC: H01M50/489
Filed: 1984-06-13
Abstract: PURPOSE:To provide a lead-acid battery having high-temperature resistant capability, high capacity, and long life by using a separator, whose electric resistance is low, acid resistance and oxidation resistance are high, made of copolymer mainly comprising acryl-butadine-styrene and alpha-methylstyrene. CONSTITUTION:In copolymer mainly comprising acryl-butadiene-styrene and alpha-methylstyrene, the ratio of alpha-methylstyrene is limited to 10% or more, preferably 30-60%. Since part of styrene is replaced by alpha-methylstyrene unlike usual acryl-butadiene-styrene copolymer resin, heat resistance and high temperature stability of this copolymer are increased. By embossing this material, a thin, microporous separator 8 is manufactured. Webs 11 of the separator are in contact with a plate and put down swelling of the plate. Therefore, coming off of the active material is prevented.

IPC: H04N7/173
Filed: 1986-05-27
Abstract: PURPOSE:To obtain a videotex message display system discriminating the repetitive reception on a display of a terminal equipment by sending simultaneously data to discriminate the sending of a new message by the terminal equipment. CONSTITUTION:In sending a message by a data storage device 21, a data string losing the character string displayed already on a display area of a terminal equipment 22 displaying the message from the display is sent. Then a person observing the display on the terminal equipment 22 recognizes once the erasure of the displayed part. Then the data storage device 21 sends the message character string to the terminal equipment 22. Thus, the person observes the display of the message on the terminal equipment 22 and recognizes the sending of a new message together with the erasure of the message display once.

Title: Magnetic bubble memory device
Inventor: INOUE HIROSHI
IPC: G11C11/14
Filed: 1982-07-13
Abstract: PURPOSE:To improve the characteristics of only inferior areas and to improve the overall characteristics of a bubble memory element, by applying the 2nd intra-face magnetic field different from an intra-face magnetic field to a local part of the bubble memory element. CONSTITUTION:Not only an intra-face magnetic field which stabilizes the start/ stop of bubbles but the 2nd intra-face magnetic field is impressed to a bubble detecting/expanding device 6, etc. for inferior areas of a bubble memory element via conductor patterns 7 and 8 which apply a local intra-face magnetic field. Thus the bubble stabilizing region is increased, and the working margin is improved. Then the characteristics are improved only for the inferior areas due to a local magnetic field without affecting other areas. This can improve the overall characteristics of a magnetic bubble memory element.

Title: Photosensitive drum braking device of copying machine
Inventor: SASAKI YUTAKA
IPC: G03G15/00
Filed: 1981-08-05
Abstract: PURPOSE:To rotate a photosensitive drum uniformly at a specified speed, by press-contacting a friction member, provided to a freely rockable member, elastically to a photosensitive drum driving member, etc. CONSTITUTION:While a photosensitive drum is driven to rotate, a rocking member 24 is released from a lock pin 30 to rock by the elastic force of a spring 31, and a brake shoe 26 provided atop of the member 24 is press-contacted elastically against a stainless plate 32 on the surface of a driven gear 11 for driving the photosensitive drum. Consequently, even if the photosensitive drum varies in torque owing to frictional force, the gear 11 which causes a back-lush to a driving gear is prevented from varying in rotational speed, and the simple constitution permits the photosensitive drum to rotate uniformly at a specified speed. Further, braking the photosensitive drum will produce the same result.

Abstract: PURPOSE:To prevent damage of member of methane fermentation tank due to freezing in cold district by opening an end of a water overflow pipe at a position of the level of digestion liquid in the main body of a methane fermentation apparatus provided with a charging port and a gas discharging port and opening another end of the water overflow pipe in a water overflow tank buried in the ground. CONSTITUTION:A main body 6 of a methane fermentation tank is constituted of an air- tight vessel having a laminated structure comprising FRP layer/insulating material layer/FRP layer with ca. 1.6m height and ca. 3m<3> volume. An outlet of a pipe 13 is provided so as to arrange the water level of the water overflow tank 10 to a position ca. 1.5 times higher than the bottom closed end of the water overflow pipe 9 than the value of water colume corresponding to the pressure of used gas. The bottom of the water overflow tank 10 is inclined in such a manner that the position of an inspecting hole 12 comes to the lowest position. When overflowed precipitate accumulates in the overflow tank 10, it is easily removed from the inspecting hole 12. Since the overflowed water is flowed down to the overflow tank 10 buried in the ground by a construction allowing the overflow pipe to pass through the bottom of the main body 6 of the fermentation tank, there is no fear of causing damage to members due to freezing of overflowed water particularly in the cold district.

Abstract: PURPOSE:To make a shock absorber compact, by absorbing a change in volume of a fluid expelled by insertion of a piston rod receiving a moving load into a cylinder by deformation of a diaphragm provided at an end portion of the cylinder. CONSTITUTION:A diaphragm 30 and a fluid chamber H communicated with a pressure port 21 are formed at an end portion of a cylinder 10 inside of an end plate 20.
