IPC: G06F17/21
Filed: 1988-07-22
Abstract: PURPOSE:To simplify an instructing input when a line feed position is altered by means of sentence editing by processing a special character code as the character code of a line feed instruction when the code is positioned in a hot zone, and processing the code with neglecting it when it is not in the hot zone. CONSTITUTION:A comparator 43 of a printing control device 4 compares the character code sent from an editing device 2 with a value 00H (the character code of the unprinted character) of a constant device 42, when a comparison result is consistent between the both codes, a level 1 is outputted from the comparator 43, and when it is inconsistent, a level 0 is outputted. When the character code of a text memory 3 is not the unprinted character code, an AND gate 45 opens the gate, and outputs the character code of the memory 3. Further, when the output signal of a NOT gate 44 is at the level 0, and the character code of a memory 3 is the unprinted character code, the gate 45 is closed, and the unprinted character code from the memory 3 is not outputted from the gate 45.

Title: Intake device of rotary piston engine
Inventor: OKIMOTO HARUO
IPC: F02B53/08
Filed: 1982-10-15
Abstract: PURPOSE:To improve the output of an engine throughout from its medium speed range to high speed range, by obtaining a supercharge effect due to the exhaust interference mutually between cylinders at high speed operation of the engine while a supercharge effect due to the inertia pulsation of each cylinder itself at medium speed operation of the engine, in the case of a two-cylinder engine of side intake port type. CONSTITUTION:At high speed operation of an engine, a compression wave, generated in, for instance, a passage 16b when an intake port 3 in a cylinder 1B is opened, is propagated to an intake port 3 immediately before full closing with a 180 deg. phase difference in a cylinder 1A by setting a passage in an adequate length between the intake ports 3, 3, and a supercharge is operated. Similarly thereafter, an output of the engine is increased by an exhaust interference effect mutually between the cylinders 1A, 1B. While a compression wave, generated in passages 16a, 16b at closing, causes inversion and reflection with expansion and compression by setting the length of a passage between each intake port 3 and an expansion chamber 21 with the reference at medium speed time, and is propagated as a secondary pulsating compression wave to the next intake port 3 immediately after opening, thus an output at the medium speed time can be improved by a supercharging effect due to the inertia pulsation of each cylinder itself.

Abstract: PURPOSE:To eliminate the dissidence of control information with a slave station by opening a window to a normal position of the slave station at first and applying normal control not via the initial connection control when a burst from the slave station is confirmed when a reference station starts the control of the slave station. CONSTITUTION:Window control information 11 is outputted to a window generating circuit 2 from a slave station control circuit 1, window information 21 is outputted from the window generating circuit 2 to a burst signal detection circuit 3, and burst signal detection information 21 is outputted from the burst signal detection circuit 3 to the slave station control circuit 1. Further, initial connection control information or normal control information 12 are outputted from the slave station control circuit 1. Thus, it is guaranteed that the control information to a reference station participating in a TDMA satellite communication system with a delay or a reference station device entering the operation state with a delay to the slave station is identical to the control information of the reference station existing in the TDMA satellite communication system already or the reference station device already in operation to the slave station.

Title: Feedback controller
Inventor: IKEDA HIDETOSHI
IPC: G05B13/02
Filed: 1997-07-08
Abstract: PROBLEM TO BE SOLVED: To eliminate stable stationary deviation with respect to disturbance and a command signal by providing a resonance controller with transmitting characteristic making a gain infinite or maximum and preventing a phase from delaying more than 0 deg. with respect to a frequency included in disturbance to input to a controlling object as a component. SOLUTION: A transmitting function device 22 is constituted by serially connecting a resonance controller 24 inputting the deviation between a command signal (r) and a controlled variable (y) and outputting the result of PI (proportional integration) arithmetic and PID(proportional integration/ differentiation) arithmetic in order to satisfactorily control transient disturbance and DC disturbance and a resonance controller 24 inputting the output of the controller 23 and outputting a manipulated valuable (u). The controller 24 is provided with transmitting characteristic preventing the phase from delaying more than 0 deg. and making the gain infinite or maximum in the frequency of the disturbance when sine or periodical disturbance exists.  Consequently, it is difficult to generate the reduction of gain margin due to the reduction of a phase and the fluctuation of a stable limit frequency.

Filed: 1989-07-14
Abstract: PURPOSE:To set an electric field substantially perpendicular to a light incident direction and to eliminate weakening of the electric field even if the length of an optical path is increased by burying an I-type amorphous silicon layer between pyramidal P-type polycrystalline layers by using the pyramidal layers. CONSTITUTION:A transparent conductive film 2 having strong oxygen etching resistance of SnO2 formed on a transparent insulting board 1 made of glass, etc., is provided.

Thus, an optical path is increased in length, light absorption amount is increased, and an electric field becomes substantially perpendicular as compared with a light incident direction. Thus, even if the length of the optical path is increased, the electric field is not weakened, thereby improving characteristics of a solar cell.

Filed: 1989-07-15
Abstract: PURPOSE:To obtain a movement guiding system for a moving body in a simple structure by obtaining the positional relation between said moving body and a road from the detecting order of the reflecting light of photodetectors and the running distance of said moving body corresponding to the photodetecting time difference of said photodetectors. CONSTITUTION:Corner cubes cc are spaced an optional distance at one side of a road 2. Each cube cc projects the reflecting light with the same angles as the angles of incidence. Meanwhile, two pairs of projectors/photodetectors 3a, 3b are mounted to a moving body 1. These projectors/photodetectors 3a, 3b are mounted to a moving body 1. These projectors/photodetectors 3a,3b project fan-shaped beams (a),(b), respectively. When the beam (a) or (b) strikes the cube cc, the reflecting light returns to the projector/photodetector 3a or 3b. An order judging circuit 4 judges which of the projectors/photodetectors 3a, 3b receives the reflecting light earlier, and supplies the result to a processing circuit 6. A running distance sensor 5 calculates the running distance of the moving body 1 corresponding to the photodetecting time difference of the projectors/photodetectors 3a, 3b, with informing the result to the processing circuit 6. The circuit 6 detects the relative position of the moving body 1 on the basis of the outputs of the circuit 4 and distance sensor 5.

IPC: G11C29/00
Filed: 1981-11-16
Abstract: PURPOSE:To process effectively an error which is due to a soft error, by holding the error information on the area where the error arises, controlling the writing and reading and transmitting the error information to a fault processor when a correctable error of the reading data is detected by a dRAM of an MOS. CONSTITUTION:This error processing system includes a CPU400, a main memory 500, an address circuit 100, a data circuit 200 and a control circuit 300. The memory 500 consists of a dRAM of an MOS. When a correctable error of the reading data is detected, the error information that specifies the area of the  fault is held. In case a correctable error is detected for the reading data following the reading data from which no error is detected, the writing and reading is performed on the basis of the held error information. As a result, a correctable error due to a soft error is distinguished from a fixed error. Thus a quick correction is given to the faulty area.
