IPC: H04B3/46
Filed: 1989-03-07
Abstract: PURPOSE:To recognize a fault location accurately and to attain automation by sending a pulse to a communication line to be tested, converting a reflected waveform of the pulse reaching a sending point after being reflected at a fault point and calculating the reflected waveform at a virtual fault point. CONSTITUTION:A transmission pulse generated by a pulse transmission section 2 is sent to a communication line 1 to be measured.

Title: Master cylinder
Inventor: KUBOTA HITOSHI
IPC: B60T11/224
Filed: 1980-04-25
Abstract: PURPOSE: To prevent loss power of depressing a brake pedal and obtain a better feeling for operation, by such means that urging force of a spring, urging the valve body of a pressure differece valve for holding a supply chamber to a certain amount of pressure, is decreased as pressure increases by a piston moved in response to the pressure in a pressure chamber.  
     CONSTITUTION: Through pressure in a pressure chamber 14 gradually rises during the time in loss of a cylinder stroke from the depression of a brake pedal till a braking effect appears, said pressure is transmitted to a cylinder chamber 36 through a passage 37 to permit the backward movement of a responsive piston 32 against a belleville spring 41, as the result the responsive piston 32 extends a spring 31 interposed between said piston 32 and a valve body 30 to weaken the urging force of said spring 31 for the valve body 30. When loss stroke operation is completed, the spring 31 in a pressure difference valve 21 extends to its free length, then a supply chamber 6 is communicated to a reservoir 2 to become the atmospheric pressure. In this way, rightward pressing force to a piston 3 due to the pressure in the supply chamber 6 is not generated, thus the loss of power for depressing the brake pedal can be eliminated.

Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a fixing device which promptly switches back and forth between standby and fixing while preventing the influence of normal temperature-control on other electric devices. SOLUTION: Each time the energization of a heater 41 is turned ON/OFF, a counter 62 carries out subtractive count from an initial count value stored in a RAM 63, and when the count value reaches '0', a CPU 61 compares a temperature detected by a thermister 46 with a reference temperature set in the RAM 63 and exerts energization/non-energization control. When receiving a preheat-ON instruction from a preheat signal generation part 64, the CPU stops the energization of the heater immediately even during the energization and shifts it to a standby condition. Conversely when receiving a preheat-OFF instruction, the CPU starts the energization immediately even during the suspension of the energization, and shifts it to a fixing condition promptly.

Title: Ink jet recording device
Inventor: YUASA HISASHI
IPC: B41J2/165
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibilities that a meniscus which is once recovered would recede with the release of a cap by providing a means for generating a pressure which generates a pressure in the cap covering an orifice face under a state that the means comes into close contact with the tip of an ink jet head, and making it possible to control the internal pressure of the cap with the help of a pressure control means. SOLUTION: If a microprocessor gives an instruction for ink suction operation to a spacing motor control part, a carriage with a mounted ink jet head 11 is transferred to a home position, so that the carriage is faced opposite to a cap 15. After that, the cap 15 is driven forward to set itself into close contact with the ink jet head 11. Consequently, the face 11a of an orifice is covered, resulting in the hermetical sealing of the interior of the cap 15. Next, the internal pressure of the cap 15 is turned negative by rotating a suction pump with the drive of a pump motor to recover a meniscus. Later, the operation enters a step to recover an atmospheric pressure after the lapse of a set time, the suction pump is reversed and the internal pressure of the cap 15 is now returned to the atmospheric pressure.
