Inventor: MATSUO MITSUKI
IPC: C07C2/64
Filed: 1989-12-20
Abstract: PURPOSE:To obtain an indane derivative useful as an intermediate for industrial chemicals, a curing agent for various resins, etc., in high yield without causing side reactions such as sulfonation by reacting a benzene derivative with isoprene using alkanesulfonic acids as a catalyst. CONSTITUTION:A compound expressed by formula I (R1 and R2 are H or 1-4C alkyl) is blended with isoprene using a compound expressed by formula II (R3 is 1-8C straight chain or branched chain or alicyclic alkyl) as a catalyst at 20-50 deg.C for 1-10hr and the blend is stirred for 1-4hr. Thereby the compound expressed by formula I is reacted with isoprene to provide the compound expressed by formula III. The raw material and product are not sulfonated and liquid-solid separation in neutralization and cleaning is remarkably improved, because sulfuric acid is not used in the above-mentioned method. Further, cooling energy is not required, because it is not necessary to carry out the reaction at low temperature. The alkanesulfonic acid can be reused.

Abstract: PURPOSE:To transmit an image by dividing by avoiding a character part when the recording paper length of the image to be transmitted is longer than that can be received by an opposite facsimile. CONSTITUTION:The number of black picture elements of line data (g) is detected by a black picture element detecting part 4, and it is stored in a black picture element storage part 5. A comparison part A3 compares the number (c) of lines with that of division reference lines, and a division line detecting part 6 reads out the number of black picture elements of the black picture element stage part 5 when coincidence is obtained, and detects the minimum number, and the number of lines that becomes the minimum number of black picture elements is set as the number (k) of division lines. A comparison part B9 compares the number (k) of division lines with the number (j) of code lines, and instructs the completion of a page to an encoder part 7 when the coincidence is obtained. The encoder part 7, when receiving an instruction representing the completion of the page, sends out code data (m) to a communication control part 10 as the final data of one page. Thereby, probability in which a dividing position coincides with the middle way of a character in an image on which the character is written can be reduced, and the division of the character extending between the pages can be prevented from occurring, and also, a defect hard to read can be solved.

Title: Button device for opening door of microwave oven
Inventor: KIN SOUCHIN
IPC: E05B15/04
Filed: 1996-12-11
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components, and to improve the workability. SOLUTION: A hook 35 is moved upward to open a door, or moved downward to close the door. A turning lever 29 is turned by the prescribed angle around the turning axis to move the hook 35 upward. An elastic piece 24 is projected from the inside of a microwave oven to the turning lever 29 and supports the turning lever 29 in one direction. The elastic piece 24 generates the bending deformation by turning the turning lever 29. The bending restoring force functions to restore a push-button 23 and the turning lever 29 to the initial position when the push-button 23 is detached. Thus, the push-button 23 can be returned to the initial position without any separate spring. The number of components can be reduced to reduce the production unit price. Because the elastic piece 24 is integratedly manufactured with the turning lever 29, the assembly can be improved.

Title: Zoom lens
Inventor: KAWAMOTO TADAO
IPC: G02B15/17
Filed: 1987-12-25
Abstract: PURPOSE:To reduce the size and weight of the zoom lens by composing a 2nd lens group of a glass lens with a high refractive index and giving negative intense refracting power, and providing a stop between the 2nd lens group and a 3rd lens group. CONSTITUTION:The 2nd lens group 2 consists of a (2a)th lens 6 which has a high refractive index and negative refracting power, and a (2b)th lens group 7 composed of a concave and a convex cemented element with a high refractive index in order from an object side, and meets requirements shown by inequalities I. In the inequalities, f2 is the focal length of the 2nd lens group, n2a the refractive index to the (d) line of the (2a)th lens, V2a the Abbe number of the (2a)th lens, and D23 the surface gap between the 2nd and 3rd lens groups. This constitution reduces the movement quantity by the zooming of the 2nd lens group and enables the stop to be provided between the 2nd lens group and 3rd lens groups, and consequently an entrance pupil shifts in position to the object side. Consequently, the diameter of the front lens is small and the overall length is shortened, thereby reducing the size and weight of the zoom lens.
