Inventor: AKASHI TAKUO
IPC: H01L29/78
Filed: 1987-07-17
Abstract: PURPOSE:To make it possible to let the title semiconductor device have a margin for the deviation of patterning even when the resolving power itself of lithography can not cope with miniaturization of a pattern by a method wherein a process, in which etching is conducted on the second gate electrode material using the pattern of an insulating film having a side frame, is provided.

Title: Power failure detection circuit
Inventor: HAMAHATA SEIJI
IPC: G01R19/165
Filed: 1988-07-15
Abstract: PURPOSE:To enhance safety by fastening support operation at the time of power failure by setting the response time at the time of power failure so as to make the same shorter than that at the time of power supply and positively feeding back the detection voltage or reference voltage of a comparing circuit so as to change the same in a non-coincidence direction. CONSTITUTION:When power failure occurs in a commercial power supply, the output of an operational amplifier IC1 is lowered with the drop of voltage Vin1 and, therefore, the charge of a condenser C2 is also discharged through a diode D2 and voltage Vin2 drops and, before long, the output of an operational amplifier IC2 changes from H to L at the point of time of Vin2 < reference voltage Vref and, as a result, Vin2 becomes lower than Vref by a feedback resistor R4. Therefore, the discharge time of the condenser C2 becoming a delay element becomes rapid. Even when slight ripple is generated in the voltage Vin1, delay is generated by a resistor R3 and the condenser C2 when the condenser C2 is charged and, contrarily, the voltage Vref becomes equal to the voltage Vin1 at the time of discharge and histeresis is brought about by the resistor R4 to make it possible to overcome such a defect that output Vout repeats H and L.

Title: Controller for unattended slave station
Inventor: HONDA SHIGERU
IPC: H04L12/40
Filed: 1980-12-16
Abstract: PURPOSE:To achieve a controller for an unattended slave station, by using a telegraphic message section of an existing communication line if a common  signal line is not usable and eliminating a station in failure from the system. CONSTITUTION:If a common signal line device 7 is in failure in an unattended slave station and a common signal line can not be used by other stations, a master station gives a disconnection instruction to a slave station via a telegraphic message section of a communication line. This instruction is fetched on the way of the telegraphic message section of the said slave station received via a communication line device 9 and when the disconnection instruction is confirmed at a code selection circuit 12, an interruption is given to a control computer 8. Thus, even if the telegraphic message section makes normal operation, although all the codes are inputted to a code selection circuit 12, the said circuit selects the disconnection instruction only, switches a device 7 to off-lines and avoids the use of common signal lines.

Title: Information processor
Inventor: HIDA EIJI
IPC: G06F9/38
Filed: 1989-07-11
Abstract: PURPOSE:To reduce the queuing time for a pipe line processing by bypassing an instruction buffer to transfer processing data in a unit length when a part of processing data concerned of the unit length required for deocding is not transferred to the instruction buffer. CONSTITUTION:A memory control unit 4 outputs an effective signal 7 to a decision selection means 8 whenever a unit instruction bit string is written in the instruction buffer 2 from a first transfer means 5. The decision selection means 8 holds storage information showing to which register in the first transfer means 5 or the instruction buffer 2 respective unit instruction bit strings are stored based on the effective signal 7. In a normal case, the unit instruction bit strings are transmitted to a second transfer means 6 through the instruction buffer 2, and are decoded in an instruction decoder 3. When the unit instruction bit string to be decoded is not stored in the instruction buffer 2, the strings are transferred to the second transfer means 6 through bypass transfer circuits P1-P4 from the first transfer means 5 by the command of the decision selection means 8.

Filed: 1982-10-13
Abstract: PURPOSE:To prevent variance in a resist an jamming of copying papers and, at the same time, to miniaturize the size of an electrophotographic device, by using either one of a pair of resist rolls as a transferring roll. CONSTITUTION:A resist roll pair 64 is composed of an upper roll 64A and lower roll 64B and the roll 64A is coupled with a driving source through a spring clutch. The roll 64B is installed in such a way that it can be contacted with or separated from a photosensitive drum 54 and it is coupled with the roll 64A by means of gears at both ends of the rolls. The roll 64B is rotated at a speed equal to the peripheral speed of the drum and, at the same time, revolved around the rotational center of the roll 64A while rotating by the rotational moment of the roll 64A, so that the roll 64B is pressure-contacted with the drum 54. A transfer bias voltage which is opposite in polarity to the toner is applied across the roller 64B synchronously to the start of rotation of the roll pair 64 and the transfer bias voltage is interrupted synchronously to the stoppage of the rotation. When such a constitution is applied, the length of the recording paper carrying passage from the roll pair 64 to a toner transferring section 59 can be shortened remarkably.

Title: Data input circuit for fuel supply controlling apparatus
Inventor: SUZUKI KAZUYASU
IPC: F02D41/28
Filed: 1983-09-27
Abstract: PURPOSE:To enable to refer to a data-map for fuel injection correctly, by connecting the output of a detector after subjecting it to A/D conversion in case that pulsation of vehicle data is caused, so that the output of the edetector may not be affected by pulsation of the vehicle data. CONSTITUTION:Output of a first clock circuit 1 is inverted to L-level, for instance, at the position 10 deg. to the top dead point of an engine. Each time the above inversion is caused, an A/D converter 2 produces an A/D converted output. On the other hand, a second clock circuit 5 produces a pulse that is inverted at the positions 10 deg. and 190 deg. to the top dead point, and the pulse is delayed at a delay circuit 6 by a time length corresponding to the time constant C1.R1. An H-level output is produced from an exclusive ''or'' circuit 7 only for the while when the above two outputs are not equal to each other. When the H-level output is produced, output of a vacuum sensor 3 is applied to an integration circuit 8 via an FET4 and then it is applied to the A/D converter after deviation of the output of the sensor 3 due to pulsation of pressure is reduced to 1/4 at the integration circuit 8. After subjecting the output of the sensor 3 to A/D conversion, it is furnished to a fuel injection control apparatus. With such an arrangement, it is enabled to refer to a fuel injection controlling data map correctly.

Title: Leak transmission line communication system
Inventor: IKEDA YUKIO
IPC: G08G1/09
Filed: 1998-06-25
Abstract: PROBLEM TO BE SOLVED: To reduce a probability that the reception level greatly decreases owing to a vehicle traveling in parallel by radiating radio waves in different directions from a leak transmission line and selecting and receiving a proper radio wave on the vehicle side. SOLUTION: The radio waves are sent and received at different radiation angles to/from a leak waveguide 1. In a form where the leak waveguide 1 having this radiation pattern is laid along a road, and in the figure, arrows indicate the radiation direction of radio wave. For example, vehicles 5a and 5b travel side by side on this road, and the leak waveguide 1 is laid on one side of the road. Consequently, a beam A from the leak waveguide 1 is cut off by the vehicle 5a on the side of the leak waveguide 1 and does not reach the vehicle 5b, but a beam B or C pass before or behind the vehicle and reaches the vehicle 5b. Therefore, the vehicle 5b selects and receives a signal having high intensity among the beams A, B, and C to reduce the probability of disturbance by the vehicle traveling in parallel.
