Title: Order wire equipment
Inventor: SHINODA MINORU
IPC: H04J3/12
Filed: 1989-03-03
Abstract: PURPOSE:To ensure smooth talking even when number of links for an order wire equipment is increased by allowing a station not making talking to send a signal not through an adder circuit to a succeeding station. CONSTITUTION:When a call comes from a transmission line 12A and its own station is busy, a DTMF(Dual Tone Multi Frequency) signal for calling from an opposite station is inputted to a talking panel 32 via a 1st branch circuit 21 and a 2nd adder circuit 26 and it is confirmed that the number is a station number of its own station. ln this case, 1st and 2nd switch circuits 53, 58 select signals 52, 57 and a signal 33 from the speech panel 32 is sent to a transmission line 12D to attain the talking. In this case, 1st and 2nd phase shift circuits 51, 56 prevent the deviation of phases by adder circuits 24, 39 when both the switch circuits 53, 58 are switched from the position of bypass. Thus, smooth talking is attained.

Title: Load model for analog system simulator
Inventor: YOKOGAWA SUMIO
IPC: H02J3/00
Filed: 1989-03-03
Abstract: PURPOSE:To reduce error of a load model by correcting wiring loss, reactance drop and voltage drop of an insulating transformer caused by the current required for constant power, constant reactive power and constant impedance Z modes. CONSTITUTION:A current amplifier 24 for a hybrid three-phase load model 10 is connected through an insulating transformer 28 with the three-phase system model 30 for a system simulator. Output from the current amplifier 24 is applied through a PT 26 onto transformer drop correction operating circuit 12 and a load characteristic operating section 14 for each mode in order to obtain a correction value for compensating the error caused by the impedance voltage drop in the insulating transformer 28 according to the load current. The correction value is operated so that wiring loss, reactance drop and voltage drop of the insulating transformer 28 occurring for specific current values 16-20 for R-T phases, under constant power Po, constant reactive power Qo and constant impedance Z modes, are corrected from the wiring specification of the insulating transformer 28. By such arrangement, error of the load model 10 can be reduced.

Title: Snubber for hydraulic cylinder
Inventor: RICHARDSON WARNER G
IPC: F16F9/49
Filed: 1998-03-03
Abstract: PROBLEM TO BE SOLVED: To provide quick stopping capability so as to harmonize at the stroke end part of a hydraulic cylinder by forming a working chamber adjacent to the end face of the hydraulic cylinder. SOLUTION: When a piston rod assembly 14 is contracted, the flange 34 of a holder 26 is contacted with the flange 68 of a sleeve 44, and the sleeve 44 is moved toward an end face 16. The sleeve 44 blocks in order ports 66 so as to limit the escape flow passage of fluid from a working chamber 18 step by step. When a piston reaches at a fixed distance from the end face 16, the fluid flow passing through the ports 66 is perfectly blocked, and the fluid flow discharged from the working chamber must be passed through a port 67. Since the fluid is passed through only the port 67 so as to discharge at minimum flow speed, the contracting motion of the piston rod assembly is smoothly controlled to stop, and impact is actually reduced at the moved end part of the stroke of the piston rod assembly.
