IPC: H04N1/40
Filed: 1990-03-28
Abstract: PURPOSE:To obtain a picture with high picture quality by interleaving and reducing an input picture signal in the unit of blocks comprising number of picture elements equal to gradation number of a pseudo intermediate tone picture, reducing a binary picture on the other hand and selecting both the pictures corresponding to the result of discrimination of a binary and pseudo intermediate tone discrimination section. CONSTITUTION:An input picture signal is inputted to a pseudo intermediate tone picture reduction processing means 13 and a binary picture reduction processing means 14 and also to a binary pseudo intermediate tone discrimination means 12. The pseudo intermediate tone picture reduction processing means 13 segments an area comprising (pXn)X(pXn) picture elements consisting of (pXn) picture elements in the main scanning direction and (pXn) picture elements in the subscanning direction from the input picture signal and an area segment means 20 segments (qXq) blocks comprising (nXn) picture elements and the result is outputted to a reduction pseudo intermediate tone memory means, where (q/p)X(q/p) is a reduction rate and (nXn) is gradation number. Thus, the picture is discriminated correctly from the binary pseudo intermediate tone mixture picture and the picture quality is kept constant without reduction in the gradation number before and after the reduction processing of the picture subject to pseudo intermediate tone processing.

Title: Steering device for automobile
Inventor: NAKAJIMA HITOSHI
IPC: B62D101/00
Filed: 1986-04-07
Abstract: PURPOSE:To prevent deterioration of steering performance at occurance of failure in a speed sensor by providing means for detecting equipment actuation during low speed travelling so as to fix the transmission ratio of the wheel steering angle to a set value when such equipment actuation is detected at occurance of failure in the speed sensor. CONSTITUTION:When failure detecting means E detects failure in a speed sensor C, control means G actuates transmission ratio changing means D to perform a predetermined operation in accordance with the detection result of low speed travel actuation detecting means F. In the concrete, it transmits a signal to the transmission ratio changing means D to fix the transmission ratio to a set value. At this time, when the low speed travel actuation detecting means F detects equipment actuation by a driver during low speed travelling, the transmission ratio is converted to the set value. Therefore, the set value may be set to an intermediate value in the variable range of the transmission ratio so as to avoid deterioration of travelling safety at occurance of failure in the speed sensor C during high speed travelling, assuring good steering performance.

IPC: B23K26/064
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To protect an external bend mirror inside the optical axis and an oscillator mirror from stains without using a counter bellows. SOLUTION: The device is constituted such that a machining head 1 equipped with an external bend mirror 21 in the oscillator 5 is provided so as to freely expand/contract, that a bellows 3 is provided enclosing the optical axis K leading to the machining head 1, that a oscillator cover 11 in communication with this bellows 3 is provided in such a manner as to surround the oscillator 5, and that an opening 15 is formed in a part of the oscillator cover 11. Consequently, the cubic measurement inside the bellows 3 changes by the expansion and contraction of the machining head 1; however, no negative pressure is caused inside the bellows 3 because of the outside air sucked and exhausted through the opening 15, enabling the external bend mirror 21 and the oscillator mirror to be protected against stains.

Title: Photoelectric switch
Inventor: TANIGAWA KIYOSHI
IPC: H03K17/78
Filed: 1988-03-31
Abstract: PURPOSE:To improve the eliminating rate of signals due to the external disturbance or noises by using a rise pulse generating circuit to produce a rise pulse having the small time width by means of the rise of a digital signal and validating the rise pulse only when it is synchronous with a projection pulse. CONSTITUTION:When a photoelectric switch is normally working, a digital signal (d) has its rise with a slight delay caused compared with a projection pulse (b) produced at a time point t1 due to the delay of a phototransistor 4 or an amplifying circuit 5 and then has the fall after an approximately fixed time. Thus an AND gate 12 produces an output pulse (g) only at an instant when these signals (b), (d) and (g) are all set at H levels. A signal (q) is set at '0' with a slight delay when a digital signal dn is produced with mixture of the disturbance light. Therefore both signals (d) and (q) are set at H levels at one time. In this case, however, the pulse (g) is never produced because the signal (b) is not produced yet and an output signal (f) is set at an L level after a prescribed time. In other words, the signal (f) is set at an H level only when the normal pulse (b) is produced. Thus no malfunction is produced.

Title: Fast arithmetic method for program block including branch instruction
Inventor: KIUCHI YOICHI
IPC: G06F9/44
Filed: 1988-03-31
Abstract: PURPOSE:To describe an easy-to-understand program and to execute the program at a fast arithmetic speed by inserting a JUMP control statement for a next block of a program block right after one execution section of each condition section, but generation a conditional statement of hierachical structure when condition sections contain exclusive logic or the same element. CONSTITUTION:It is decided whether the condition sections of >=2 condition statements contain exclusive logic or the same element. In the former case, a jump control statement for making a jump to a next step of a program block is added right behind the condition statement and in the latter case, on the other hand, the same element is regarded as another condition statement and converted into the condition statement of hierachical structure. Thus, the condition section is represented as the logic value of one element or >=2 elements, so the program is easy to understand and when the condition of the condition sections of >=2 condition statements is exclusive logic, a jump to a next step of a program block is made right after each condition statement; when >=2 condition statements contains the same element, the statement is converted into the condition statement of hierachical structure, so the program execution is speeded up.

Filed: 1984-04-23
Abstract: PURPOSE:To shorten a transfer time by transmitting a message to the third party in accordance with the request of a terminal or an attendant board and connecting automatically a calling party and the third party thereafter. CONSTITUTION:In case that an incoming call comes from a terminal B to a terminal or a B board A and is transferred to a terminal C, an exchange 2 is requested to connect the call to the terminal C by service. Thereafter, the terminal or the B board A is in the on-hook state, and the exchange 2 suspends the terminal B by a trunk circuit 6 and reserves a message circuit 8 to call the terminal C. When the terminal C responds to this call, the exchange 2 connects a message storage circuit 8 and the terminal C and starts the circuit on a basis of the indication from a control part 12 to transmit the message to the terminal C. When the terminal C responds to this message, the exchange 2 connects terminals B and C after a certain time, and the open indication is issued to the circuit 8 from the control part 12.
