Abstract: PURPOSE:To obtain high transmittivity and a high contrast ratio, and also, to allow a display picture electrode to have a high performance so as not to generate a flicker, by providing a second display picture element electrode connected to a display picture element electrode formed on a first substrate, on the latter. CONSTITUTION:On the first substrate 31 on which a thin film transistor having a semiconductor film 34 between a drain 39 and a source electrode 40, and a display picture element electrode 38 are arrayed, and formed like a matrix, so as to oppose a gate electrode 32 provided on an insulating substrate, the second display picture element electrode 45 is formed so as to be superposed on a signal line and the gate electrode 32. Also, in a gap of the first substrate and the second display picture element electrode 45, a light shielding electrode 43 is formed so as to be superposed on the second display picture element electrode 45. In such a way, comparing with a conventional device, the numerical aperture becomes larger, therefore, high transmittivity is obtained, and also, since the light shielding electrode and the second display picture element electrode are superposed, a high contrast ratio, and a picture plane being free from a flicker can be obtained.

Filed: 1991-05-30
Abstract: PURPOSE:To contrive the improvement of mass productivity as well as energy saving by a constitution wherein a heating tube is arranged so as to be estab lished vertically to reduce the area of installation while the calcining reaction of the material of ceramics, thrown from the upper part of the heating tube, is finished during a time until it arrives at an lower opening. CONSTITUTION:When the raw materials of ceramics are thrown into the vibration feeder 12 of a throwing means 5, said raw materials are mixed and supplied with a predetermined speed to thrown them through the upper opening of a heating tube 1. Then, said raw materials are baked by the sheath heater of a heating means 2 with heat necessary for the calcining reaction of the materials and, thereafter, are descended through the spiral blades 9 by the rotation of a screw means 3. The calcining reaction can be achieved during the period of dropping by setting the length of the heating tube 1, the heating temperature and said descending speed properly. The adhesion of the raw materials to the inner wall of the heating tube 1 is prevented by an oscillating means 4. The material of ceramics, which have finished the calcining reaction thereof, become a block and obtained from the lower opening of the heating tube 1, however, said block is dropped on a receiving unit 6 and crushed roughly.

Title: Solenoid attraction method
Inventor: NAKATSU HARUHIKO
IPC: H01F7/18
Filed: 1997-05-02
Abstract: PROBLEM TO BE SOLVED: To prevent increase in size of a solenoid and increase of power consumption, and to make it possible to guarantee a latch operation and a attraction operation, by a method wherein a prior attraction signal with which the material to be moved is operated is given to the solenoid, before giving a attraction signal to attract a plunger to the solenoid. SOLUTION: A prior suction signal is given for a short period immediately before giving an attraction signal in this solenoid attraction method. Accordingly, as a shutter performs an opening and closing movement in the degree wherein the shutter is not brought in a latched state, the frictional force of sliding surface is reduced by the warming operation of the shutter. As a result, the Δt when the attraction signal is given can be brought to the state approximate to the case where the frictional force is not increased so much, a latched state can be firmly maintained and image density can be detected accurately. Also, as the contamination of the window of an image density detector can be brought to the minimum, the value of toner density can be maintained appropriately at all times.

Abstract: PURPOSE:To secure the autonomous traveling of a traveling object with no going-off from a prescribed straight route, by always monitoring and controlling the traveling amounts of the right and left track and multiplying the output of an encoder by the correction value so that the traveling object is always kept in the fixed direction. CONSTITUTION:The outputs EL and ER of the left and right integration counters 12L and 12R are supplied to a subtractor 13 and a calculation ER-EL=epsilonDig is carried out with digital signals as they are. This epsilonDig means the difference between the amounts of the left and right track 20L and 20R and then converted into the voltage value epsilon even with a code taken into consideration. The voltage value epsilon showing the directional deviation is multiplied by the appropriate feedback gain Kf via a direction feedback amplifier 15. Thus an output VFB is obtained and supplied to a subtractor 2 in a right motor system and to an adder 3 in a left motor system respectively. Then the output VBF is fed back to keep the straight direction of the traveling object.

Filed: 1982-07-22
Abstract: PURPOSE:To facilitate a lubricating agent feeding operation and provide a smoothed assembling operation by a method wherein an inner groove formed at an inner surface of a bushing is communicated with an outer groove always communicating with a lubricating agent supplying port. CONSTITUTION:An endless inner groove 14 extending in a circumferential direction is formed at an inner surface of a bushing 5 which is formed by an annular plain sheet 13, and a cap 1b is formed with a circumferential outer groove 18.

Abstract: PURPOSE:To calculate an error rate at high speed and with high accuracy, by counting the number of error pulses at every frame decided in advance by a counter means based on a frame pulse and the error pulse generated from a decoder, outputting a monitoring signal, and outputting an alarm signal when the value exceeds a prescribed value. CONSTITUTION:An OR circuit 11 outputs the number of pulses equivalent to the sum of the number of errors in eight groups. A frequency divider (1)13 outputs the pulse at every frame from which a comparatively a large number of errors are generated, and a counter (1)14 is the one capable of measuring up to a comparatively low error rate, and the monitoring signal 15 representing the error rate is outputted at every input of the pulse from the frequency divider (1)13. A counter (2)17 outputs the alarm signal 18 when the errors exceeding a prescribed number of errors equivalent to a comparatively high error rate set in advance are counted. Thus, by using the error pulse outputted from the decoder provided with the correction means of plural groups, the error rate can be detected at high speed and with high accuracy without using a parity check bit. And it is possible to output the alarm signal to be used in line switching, etc., appropriately based on the above detection.
