Title: Change retainer of press machine
Inventor: ITO HIDEAKI
IPC: B21D28/34
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce the size of a change retainer by forming a cam on a piston rod of a cylinder device, which advances/retreats a punch or a die to an using position with a large protruding quantity and a non-using position with a small protruding quantity. SOLUTION: When a piston rod 14 is protruded, a cam 24a in front thereof makes a protruding part of a spring receiver 9 slide in the horizontal direction by an inclined face of a front end, further, by sliding a rear edge of an upper end part of a punch 6, the spring receiver 9 and the punch 6 are pushed down against the energizing force of a return spring 11. By this method, the punch 6 is made to be in a large protruding state. When descending the punch holder 1, the punch 6 hits a work 4 to punch the work. By this method, the change retainer can easily reduces its size, a design freedom for layouting punch/die is improved, also, maintenance of a cylinder device is made easy.

Abstract: PURPOSE: To enable a dimension measuring instrument to measure the uneven color and contamination of a translucent object and the dimension of an object to be measured with high accuracy by discriminating the quality of the object from the sum total of the received light quantities calculated from the stored gray level data of all picture elements and the width of the object calculated from binarized data. CONSTITUTION: After a CCD 21 completes one scanning operation, a CPU 36 reads out the gray level data of all picture elements of a picture memory 33 and calculates the sum total of the received light quantities by integrating the gray level data of all picture elements. The CPU 36 also reads out binarized data from a binary memory 35, finds the coordinates of edges by finding the addresses at which the binarized data change from '0' to '1' or from '1' to '0', and calculates the width of a work M from the coordinates. A discriminating and outputting section 37 discriminates the quality of the measured work M by comparing the sum total of the received light quantities and width of the work M with the preset and stored defectless data of the work M.

Title: Organic film for optical compensation and production thereof

Filed: 1988-03-01
Abstract: PURPOSE:To enable colorless display and high-contrast display by constituting the above film of a polymer film which has no selective scattering wavelength within a visible region and contains an oriented chiral nematic (cholesteric) liquid crystal having a spiral structure. CONSTITUTION:The org. film for optical compensation consists of the liquid crystal polymer film which has no selective scattering wavelength lambda0 in the visible region and has the spiral structure. The chiral nematic liquid crystal polymer film exhibits circularly polarized dichromaticity by generating selective scattering to the light of the specific wavelength corresponding to lambda0=p.nfcospsi (p is a spiral pitch, nf is the refractive index of the film, psi is the deviation angle between the orientation of the incident light and the orientation of the spiral axis). Such org. film for optical compensation has the function to return the elliptically polarized light which is emitted from the twisted nematic liquid crystal layer of TN and STN and has an optically rotatory power to linearly polarized light. Also the film has the function to compensate the wavelength dispersion of the double refraction exhibited by the nematic liquid crystal layer. The degree of coloration of the display is thereby decreased and the display contrast is increased.

Title: Toner end detector of copying machine
Inventor: KIMURA KAZUHIRO
IPC: G03G15/08
Filed: 1980-04-14
Abstract: PURPOSE:To prevent malfunction owing to uneven existence of the toner by outputting a detection signal when an end signal inputs continuously more than twice in a toner end detector for a copying machine which detects toner amount periodically. CONSTITUTION:When a pulse Sp is generated from a mechanism 10 which detects the residual amount of toner, the fall pulse by a differentiating circuit R1-C1 turns a transistor Tr1 on, thereby charging an integrating capacitor C2. Before the Tr1 goes OFF, a buffer amplifier 13 conducts to input an AND circuit 14. When the pulse Sp generates again before the amplifier 13 turns OFF upon discharging of the capacitor C2, a transistor Tr2 goes ON, and the another terminal of the AND circuit is inputted so that the toner end signal SE is inputted to a control circuit. The error of detection caused by the malfunction of mechanical parts owing to the uneven existence etc. of the toner is reduced.

IPC: G03G15/00
Filed: 1990-02-28
Abstract: PURPOSE:To make a device highly adaptable to the synchronizing pulse of a photosensitive body and to make the device suitable for high-speed and high-accuracy operation and multifunction by executing the interruption processing of the start/finish of a copying process corresponding to timing data by which a copying process sequence is decided corresponding to an interruption signal and outputting next timing data. CONSTITUTION:Pulses generated in synchronism with the specified small quantity of movement of the photosensitive body 4 are counted by the external counter 41(40) of a microcomputer 21. When the counted value coincides with the timing data by which the copying process sequence is decided and which is outputted from the microcomputer 21, the interruption signal INT is generated. The microcomputer 21 executes the interruption processing of the start/finish of the copying process corresponding to the timing data in response to the interruption signal INT and outputs the next timing data. Since the interruption processing need not be executed every time the synchronizing pulse arrives at, the synchronizing pulse is made to have high resolution and the accurate control of the sequence timing is realized. Thus, a copying device which is suitable for the high-speed and high-accuracy operation and multifunction is obtained.
