Patent JP-H11317780-A (JP)
Title: Demodulating device of receiver
Inventor: SHIRAISHI KENICHI
IPC: H04L27/227
Filed: 1999-02-25
Abstract: PROBLEM TO BE SOLVED: To miniaturize a circuit scale. SOLUTION: A timing circuit 30 detects a burst symbol signal section from outputs I and Q of a demodulating circuit 1A which performs orthogonal detection of a received signal generated by time-multiplexing BPSK-, QPSK-, and 8PSK-modulated digital signals while a pattern regenerating circuit 40 outputs the same PN code pattern as the transmission side. Inverting circuits 13 and 14 outputs I and Q as RI and RQ for bits '0' of the PN code pattern, and -I and -Q as RI and RQ for bits '1'.  An phase error table 15A contains phase errors between the phases of received signal points of the outputs of the inverting circuits 13 and 14 and the absolute phase for the 1st quadratures of RI and RQ, and a phase error detecting/processing circuit 16A reads out phase errors corresponding to the absolute values of RI and RQ and adjusts them to data corresponding to the quadratures where RI and RQ are present. A carrier regenerating circuit 10A corrects the phase of a reference carrier used for orthogonal detection so that the phase error after adjustment becomes zero.

Title: Coupling method of metal member
Inventor: TERAJIMA KUNIO
IPC: B21D39/04
Filed: 1979-04-23
Abstract: PURPOSE: To secure the two members to be coupled at even strength without using any pressing jig by inserting a coupling member having deformation resistance smaller than that of said members and desired mechanical strength between the faying surface gaps of said members and pressure-sliding said both members to press the coupling member thereby causing plastic deformation.  
     CONSTITUTION: After a coupling member 3 is inserted to the member 1 to be coupled, the member 2 to be coupled 2 is inserted. Next, the one member to be coupled is fixed and the other member is slide-pressed in the arrow direction or the both are pressured in the mutually opposite directions, then the coupling member 3 is plastically deformed by this pressure and at the same time the coupling member 3 plastically flows in the recesses b 1 , b 2  provided in the opposing surfaces in the spacing part A, by which the spacing part A is sufficiently filled by the coupling member 3. With this method, the material for the members to be couplied is required to be harder and has large rigidity than the coupling member 3.

IPC: B23K9/04
Filed: 1986-03-05
Abstract: PURPOSE:To extend the roll service life by performing a rough finishing with the primary welding of the metal having wear resistance, etc. on the shell part surface of a roll, then by performing secondary welding in succession by leaving the gap of nonweld on the whole periphery of the high stress loading zone of the shell part. CONSTITUTION:The whole face buildup welding 4 is performed of the metal having a heat resistance, wear resistance and corrosion resistance and formed in rough finishing dimension on the surface of the base metal 3 of a roll shell part 1. The continuous secondary welding of the service deposit metal 8 leaving a nonweld gap 7 is performed on the whole periphery of the high stress loading zone of the shell part 1 and subjected to a cutting upto the finishing dimension. The deposit metal 8 is formed so as to reduce its heat resistant fatigue performance, so the crack generated on the roll surface relieves the thermal stress at the part thereof and can prevent its development to the roll shell part 1. Consequently the roll life can be extended.

Title: Engine driving generator
Inventor: SAYAMA MICHIO
IPC: H02P9/04
Filed: 1980-04-17
Abstract: PURPOSE:To save the fuel consumption by reducing the revolustions of the engine when unloaded while the revolutions thereof is turned to the rated one when loaded. CONSTITUTION:When a generator 2 is unloaded, the output of a current transformer 4 becomes zero to close a contact (b) of a relay device 5. This actuates a deceleration relay 6 to excite a solenoid 7 whereby a governor 8 of the engine 1 moves to a low speed position. When loaded, the current transformer 4 outputs current to turn the governor 8 to the rated rotation position. Thus, the fuel consumption can be reduced.

Title: Fuel injector for engine
Inventor: FUJITA NAGAHISA
IPC: F02D41/14
Filed: 1984-03-15
Abstract: PURPOSE:To obtain the proper air-fuel ratio of the mixed gas in each cylinder of an engine by the simple constitution without adjusting the timing of fuel injection signal by generating a special fuel injection signal corresponding to the air- fuel ratio state in each cylinder and increasing the amount of fuel in the cylinder in which the air-fuel ratio is lean. CONSTITUTION:When the air-fuel ratio of the mixed gas in the third cylinder 1c is lean, initial setting is performed so that a special fuel injection signal is outputted from a CPU15 in each prescribed timing at about 60 deg. before the start of the intake cycle of the third cylinder 1c. Then, the properness of the generation timing of this special fuel injection signal is judged according to the signal supplied from an air-fuel ratio sensor 13, and the timing is adjusted to the advance side or delay side, having about 60 deg. before the start of the intake cycle of the third cylinder 1c, as standard. The air-fuel ratio of the mixed gas is gradually adjusted to a set air-fuel ratio by the increase of the fuel amount on the basis of the special fuel injection signal. Therefore, the air-fuel ratio of the mixed gas in each cylinder 1a-1d of an engine 1 is made uniform to the set air-fuel ratio.

An added value which the adder 43 adds the two outputs is stored in the latch circuit 44 with the clear. The above-mentioned operations are repeatedly carried out by the coordinate i from '0' to 'Nx' (horizontal scanning period). Thereby, the output of the latch circuit with the clear 44 is renewed from (a1.i) to [a1.(i+1)] to [a1.(i+2)].
