Title: Tool chuck
Inventor: NAKAMURA DAIJIRO
IPC: B23B31/12
Filed: 1993-02-26
Abstract: PURPOSE:To chuck a tool firmly without using a chuck handle by holding a revolving ring where a large-diameter female thread is engraved at the same pitch as a male thread engraved at the outer periphery of a nut ring so that it may be rotated at an operating ring in an eccentric condition. CONSTITUTION:This tool chuck 10 is provided with plural chuck claws 12 in the central part of a chuck body 11. A nut ring 15 which screw-feeds the chuck claw in an expanding/contracting direction is screw-engaged with a female thread 14 engraved in the outer periphery of the chuck claw 12. The rotational force of an operating ring 21 fitted onto the chuck body 11 is transmitted to the nut ring 15, so that the chuck claw 12 is contracted to chuck a tool. In this case a male thread 18 is engraved on the outer periphery of the nut ring 15. On the other hand, a revolving ring 19 on which a female thread 20 of large diameter is engraved at the same pitch as the male thread 18 is disposed. In an eccentric condition with the female thread 20 screw-engaged with the male thread 18 the revolving ring 19 is held on the operating ring 21.

Title: Knocking detector
Inventor: MAKI ICHIROU
IPC: G01M15/00
Filed: 1982-04-14
Abstract: PURPOSE:To detect knocking exactly up to a high-speed revolution by detecting knocking in the entire crank angle range without generating a knock gate for detecting the knocking at the high-speed revolution of a certain specified number of revolutions or above. CONSTITUTION:The output of a timing generation circuit 11 and the output of a detection circuit 13 for number of revolutions is ANDed to prohibit the generation of a knock gate at a certain specified number of revolutions or above. More specifically, the output of the circuit 13 is set to ''L'' at a low speed revolution and the output thereof is set to ''H'' at a certain specified number of revolutions or above. Thus, the knocking is detected in the period when the knock gate is ''H'' at the low-speed revolution and the knocking is detected irrespectively of the knock gate at the certain number of revolutions or above. The triangular wave generating circuit 15 in the circuit 13 generates a triangular wave during the next ignition timing from the ignition timing and the output thereof is average in an averaging circuit 16. Therefore, the output of the circuit 16 is changed in the average value by the number of revolutions and said average value and the voltage determined beforehand with a potentiometer VR are compared in a comparator 17, whereby the prescribed number of revolutions is detected. The knocking is thus detected at the timing when the knocking is generated at the low-speed revolution and the knocking is detected exactly without overlooking the same at the high-speed revolution as well.

Title: Picture signal processing system
Inventor: YAMADA MASANORI
IPC: G06T1/00
Filed: 1983-04-12
Abstract: PURPOSE:To make each line binary without requiring a picture signal preserving memory nor auxiliary scanning by changing successively the threshold level of a prescribed scanning line on a basis of the texture density, which is detected in scanning before scanning of the prescribed scanning line, to make the line binary. CONSTITUTION:The detected texture level of the first main scanning line and the threshold for binarizing the i-th main scanning line are denoted as Wi and Si respectively. When scanning is started, a CPU 208 outputs S1=(3F(HEX)-W0)Xk +W0 to the first line. In this equation, 0<k<1 is true, and 3F(HEX) is a density level for the darkest of each picture element after A/D conversion. Since picture informatin before the first line does not exist, W0=0 is supposed for the first line. After the first line is made binary by the level S1, the CPU 208 takes in a texture level W1 in the first line, for which scanning is just terminated, synchronously with a synchronizing signal and outputs S2=(3F(HEX)-W1)Xk for the purpose of binarizing the second line. Hereafter, the i-th line is binarized with Si=(3F(HEX)-Wi-1XK+Wi-1similarly.

Title: Method and device for adaptive differential decoding
Inventor: AIKOU SHINICHI
IPC: H03M7/32
Filed: 1982-04-14
Abstract: PURPOSE:To prevent the generation of a fault of an adaptive differential coder or a large DC signal and oscillation to the output signal of an adaptive differential decoder, by deciding whether the result of coding has the same value at eath time. CONSTITUTION:A quantization step is supplied to a deciding circuit 505 from an adverse quantitizer 162. When it is decided that the value of the quantization step is equal to a level which is impossible to obtain in the normal state, ''0'' is delivered to a signal line 551. Therefore the coding result U1 is set at the same value at each time, and the quantization step is set at a level which is impossible to obtain in the normal state. In such a state, the output of a decoder is set at 0. Otherwise a decoding signal xj is delivered. In such a way, the output of a decoder is never turned into an extremely large DC signal or an oscillating signal even though a coder has no working or a signal line is interrupted.

IPC: H04L12/403
Filed: 1980-05-15
Abstract: PURPOSE:To reduce the installation cost of lines and to decrease the waiting time of slave stations, by enabling the communication as if it were a straight line between two points logically, although it is a branched connection line physically. CONSTITUTION:At an idling state of communication, the YNSC code signifying a noncommunication state as shown in Figure from the terminal S of the master station is transmitted to a communication line 101. Further, each slave station receives it at a reception terminal R and recognizes the idling state. When a slave station 1 starts the communication, the enquiry sequence (SA1, UA, ENQ) for data link establishment is transmitted. A master station 10 stops the transmission of the YNSC code with the reception of this signal and returns the ACK to establish the data link between the master station 10 and the slave station 1. Further, if the communication is finished, the master station 10 transmits the idle signal again to be returned to the initial state.
