Title: Intermediate discharge device of pivoted bucket elevator
Inventor: ITOU REIZOU
IPC: B65G47/40
Filed: 1981-12-02
Abstract: PURPOSE:To surely perform smooth discharge of a material with simple construction, by providing two guide rollers in left and right side bottom parts of a bucket and forming the bucket such that the bucket tilted by one guide means is overturned by the other guide means to discharge the material. CONSTITUTION:When guides 24, 25 of a bucket are in an ascending position, the guide 24 scoops up a guide roller 15 by an ascending slope 26 to tilt the bucket 3 clockwise in a relatively gentle state of tilting motion. A guide roller 14, after passing through immediately below a roller shaft 2 by tilging motion, runs on the guide 25 from its ascending slope 27 to its top surface 28 to further tilt the bucket 3. The top surface 28 at its ascending is placed in the upper center of a hopper 4, and the bucket 3 is tilted to an overturned attitude to discharge a transfer material S to the hopper 4. Then if the roller 14 is contacted to a slope 29 to descend, a tilt angle of the bucket 3 is decreased, and the roller 15 is contacted to a slope 30 of the guide 24 to descned then the bucket 3 is reset to a horizontal attitude.

IPC: G02B5/32
Filed: 1988-08-02
Abstract: PURPOSE:To eliminate the need for a filter to be additionally provided and to reduce manhours by dividing a holographic grating on a diffraction element into plural areas so that the transmittance of the zero order diffraction light of the areas positioned at both edges in a direction corresponding to the radial direction of an optical disk can be made smaller than that of the area positioned in a central part in the direction. CONSTITUTION:The holographic grating on a diffraction element 13 is divided into plural areas 13a-13f in the direction corresponding to a radial direction B-B' of an optical disk 16, and the transmittance of the zero order diffraction light in the areas 13c-13f at both edges in the direction corresponding to the radial direction B-B' is set so as to be lower than the transmittance of the zero order diffraction light in the areas 13a and 13b positioned in the central part in the direction corresponding to the radial direction B-B'. Consequently, to the holographic grating itself, a filtering function for suppressing secondary maximum components is given. Thus, since the conventional filter does not need to be formed, the manhours can be reduced.

Title: Color liquid crystal display device
Inventor: UCHIKAWA YOSHIRO
IPC: G09G3/36
Filed: 1984-09-14
Abstract: PURPOSE:To uniform transmissibility and to attain the precise color expression of a color liquid crystal panel by compensating a driving voltage to be applied to R, G and B picture elements in each color. CONSTITUTION:A display panel has a matrix structure consisting of N X (scanning) electrodes and N Y (signal) electrodes. Color filters are arranged so as to be matched along the Y electrodes and respective Y electrodes for R, G and B are connected to Y drivers 2-4 formed independently in each color. A picture signal is converted by an A/D converter 6 and its digital data are latched by the Y drivers 2-4 corresponding to respective colors on the basis of a timing signal outputted from a control circuit 7. On the other hand, the scanning electrodes are driven by an X driver 5 and the difference of transmissibility of R, G and B can be compensated by applying a different Y voltage in each color out of R, G and B. Consequently, more precise color expression can be attained without losing a visual angle characteristic and a response speed.

SOLUTION: The surface roughness of the glass substrate to be formed with a corrosion resistant film is strictly controlled to <=0.4m in the center line average roughness Ra in order to suppress the occurrence of nonuniform etching by the actual appearance of latent flaws and the peeling of the corrosion resistant films and to form the circular contours when the microrecessed parts are viewed plane. The microrecessed parts formed by the etching method are in an approximately bowl shape and the radius of curvature in the bottoms is set larger than the radius of curvature of the side parts. The contour when the microrecessed parts are viewed plane is nearly circular. Further, the ratio of the major diameter (b) and minor diameter(a) thereof is so determined as to attain <=1.1.  The b/ a of the contour of the recessed parts formed by the etching attains <=1.5 when, for example, the Ra of the glass substrate attains >=0.55nm further, the contours thereof are made irregular and are no longer regarded circular.

Filed: 1981-12-02
Abstract: PURPOSE:To prevent a fault, by providing a circuit for detecting the connection failure of a signal terminal when installing an attachment, and stopping its installing operation in the event of the connection failure. CONSTITUTION:When a pin 7a of an attachment 6 of an interchangeable lens, etc. is fitted into a notch part 1A of a bayonet pawl la1, each signal terminal is connected. This connecting state is decided by detecting a voltage drop of these terminals by a window comparator in case when a camera side signal terminal is in high potential, and in case when all is satisfactory, ''0'' is outputted from an NAND gate. As a result, a plunger operates, a moving piece 3a shunts, and a rotation clamping operation of a bayonet is allowed. On the other hand, in case of connection failure, an output of the NAND gate remains ''1'', and the moving piece 3a holds its position as it is, therefore, the rotation clamping operation is stopped.

Title: Direct current magnet control system for electromagnetic contactor
Inventor: ONO MINORU
IPC: H01H47/00
Filed: 1988-08-05
Abstract: PURPOSE:To provide a long lifetime and reduce the electric power consumption by controlling into a constant current necessary for attracting motion of a DC electric magnet in the attracting motion period of DC electric magnet, controlling into a constant current needed for holding in the attraction and holding period, and thereby excluding excessive collision energy independent from changing source voltage, ambient temp., and coil temp. rise. CONSTITUTION:In the attracting motion period of an electric magnet an electronic switch 104 is shut, while another 103 is controlled by a constant current auto-control device 6 to provide a constant current value, which is optimum for attracting motion. As the number of turns of a coil 2 is constant, the attraction energy supplied to the electric magnet is controlled into optimum constant value regardless of the source voltage, ambient temp., and coil temp. in rising. During hold period after completion of attraction the electronic switch 103 is alike controlled to hold a constant current value greatly smaller than the attracting motion, which is optimum for hold motion. Accordingly the hold energy is controlled constant independent from the source voltage, ambient temp., and coil temp. in rising.
