Title: Sheet for protecting photosensitive element
Inventor: MIURA SHINICHI
IPC: G03G21/00
Filed: 1981-05-25
Abstract: PURPOSE:To protect the surface of a photosensitive drum and prevent the photosensitive layer from light fatigue by covering the drum with an attachable/detachable opaque flexible sheet. CONSTITUTION:A photosensitive drum 3 for an electrostatic copying machine is completely covered with a cylindrical protection sheet 1 consisting of a polyester flexible sheet or the like whose surface is coated with a carbon layer to apply opaque treatment and utilized for the attachment/detachment of the drum to/from the copying machine. It is adopted to wind an endless cylindrical protection sheet 1 around the drum. In addition, knob parts 2c are convenient for attachment/detachment of the drum. Since the protection sheet is opaque and checks the transmission of light, the surface of the photosensitive drum can be prevented from light fatigue.

Title: Method for arranging display pixel and color displaying element
Inventor: KIA SHIRUBUAABURUTSUKU
IPC: G02F1/141
Filed: 1995-03-13
Abstract: PURPOSE: To effectively utilize an image to be displayed for color gradation display without easily generating an error of display levels or distortion to be sensed by human eyes on the picture by allocating the number of lighting enabled areas based on each visual sensitivity to each primary color component. CONSTITUTION: A maximum error sensed by human eyes is applied to the weighted visual sensitivity of user's eyes, or resultantly the number of driving lines to minimize the maximum error sensed by human eyes. In this case, one pixel having six driving lines divided into two red driving lines 18, 19, three green driving lines 20 to 22 and one blue driving line 22 is arrayed for display. Human eyes most sensitive to green easily increase errors due to the discontinuity of green sub-pixels as compared with other two primary colors (red and blue). Since human eyes are not so sensitive to blue as compared with green and red, errors in the blue primary color are quiet.

Title: Oil-pressure circuit for oil-pressure shovel
Inventor: YOSHIMATSU HIDEAKI
IPC: F15B11/16
Filed: 1981-05-26
Abstract: PURPOSE:To raise the efficiency of turning control for an oil-pressure shovel by using a system in which the supply of oil to a turning motor or the discharge of oil fromthe turning motor is controlled by switching a turning direction  control valve by lever operation and also an oil-pressure pump is put into on- load by switching an unload circuit control valve. CONSTITUTION:At the time of turning acceleration, the secondary side pressure of a remote control valve is controlled by an operating angle to the direction of arrow (a) of a lever 61, the opening area of a turning direction control valve 51 is controlled according to the secondary side pressure, the opening area of an unload circuit control valve 45 is also controlled likewise, and the supplying pressure and flow rate of oil to a turning motor M3 from an oil-pressure pump P2 are controlled. Thus, when the operating angle to the direction of arrow (a) of the lever 61 is small, the supplying pressure of oil to the motor M3 is reduced and the turning is accelerated under low pressures, and also when the operating angle is increased, the turning is accelerated under high pressures. Control can be attained by operating the lever 61 during the turning acceleration period.

IPC: G21C7/16
Filed: 1993-04-07
Abstract: PURPOSE:To provide a hydraulic-drive control rod drive device which realizes the drop of the rorary moment of horizontal load on a piston by further reducing the stiffness of a spear. CONSTITUTION:A hydraulic-drive control rod drive device is equipped both with a fixed latch component 51 fitted with a holding seat 38 installed in the upper part of a cylinder 2 mounted in a reactor vessel head and with a support pole 52 fitted with a head 52a installed in the upper part of a piston component 4. The fixed latch component 51 includes both a latch passage which receives, guides and latches the head 52a of the support pole 52 on the holding seat 38 by synchronizing with a device which controls hydraulic pressure in the upper and lower parts of the piston component 4 to raise and lower the drive shaft and an unlatch passage which guides the head in this holding seat 38 and releases it outside the fixed latch component. This means that the fixed latch component 51 has the three functions for the support pole 52 such as latching, unlatching and holding and that the support pole 52 works, displaced along an unlatching passage. Consequently, the stiffness of the support pole 52 is reduced.

Abstract: PURPOSE: To set auxiliary machine driving voltage regardless of the voltage of a generator so as to stabilize engine performance quality by actuating a starting three-phase power converter as the switching part of an auxiliary machine driving circuit after the completion of start. CONSTITUTION: When a gas turbine engine is started and the engine speed rises to the preset specified value, a switch 43 is turned off to terminate engine assist at the start time, and a relay 53 is switched to the terminal 54 side. The transistors 26a, 26b, 26d, 26e, 26f of a starting power converter 23 are then turned off, and the transistor 26c is changeover-controlled to supply a direct current of specified voltage to an auxiliary machine driving power circuit. When the inter-terminal voltage of a smoothing capacitor 55 in the auxiliary machine driving power circuit is judged to have risen higher than the voltage of a battery 41, a switch 42 is turned off to stop the driving of an auxiliary machine 38 by the battery 41.

Abstract: PURPOSE:To prevent the leakage of sodium in a luminous tube to the outside of the tube during operation by sealing an electric conductor provided with yttrium oxide film on the surface in the aperture of the end of an alumina tube with ceramic cement containing calcium oxide. CONSTITUTION:An alumina tube 1 and an end disk 2 and an electric conductor 6 are sealed together with rings of ceramic cement 8 by heating up to a high temperature and melting the said cement.

Abstract: PROBLEM TO BE SOLVED: To prevent malfunction of a CM(commercial message) skip operation by measuring a period between events (silent parts) detected at the time of video recording, discriminating an event between a CM and a program regular section and an event between CMs and storing the event between the CM and the program regular section, a min. value of the discriminated event period and information about a program starting/ending position on a tape in a memory. SOLUTION: When video recording is started up, a measuring result outputted by a BF(black frame) silent part period measuring part 10 and a BF-BF period measuring part 9 based on a detecting signal from a BF detecting circuit 6 and a silent part detecting circuit 7 is compared with a prescribed threshold by a CM-program regular section BF silent part discriminating part 11, and when the result is more than the threshold, this is decided to be the BF silent part period between the CM and the program regular section, and a min. period of the BF silent part period is recorded in the memory 12. The information about video recording starting/ending position on the tape is stored in the memory 12 by a VTR control part 13. By this method, at the time of reproducing, the CM skip operation without malfunction can be carried out.

Filed: 1982-05-17
Abstract: PURPOSE:To easily make a diagnosis in a short time by an apparatus which comprises a pulsation detector for detecting oil pressure pulsation, a pulsation separator for separating part oil pressure pulsation due to a component of a rotary oil hydraulic unit from output of the pulsation detector, etc. CONSTITUTION:A failure diagnositic apparatus includes a hydraulic pump 1 which is driven with the number of rotations and the discharge pressure both being held constant. In this state, oil pressure pulsation in a pipe line 2 is converted to a change in voltage by an oil pressure pulsation detector 3. Then, output of the oil pressure pulsation detector 3 is amplified by an amplifier 4, and the change in voltage corresponding to part oil pressure pulsation due to a plunger part is taken out by a pulsation separator 5. Next, a failure ratio D is determined in an arithmetic unit 6 based on voltage values of first and second peaks to judge the degree of failure in the plunger part. By so doing, it becomes possible to make a diagnosis with ease in a short time.
