Abstract: PURPOSE: To reduce the heat generation quantity and facilitate the regulation of the rising of the current flowing through coils by providing a signal generating means which supplies a driving signals to the root selecting switch and another signal generating means which supplies a driving signal to the coil driving switch.  
     CONSTITUTION: A transistor (TR)9 for selecting the flyback root and transistors TR10 for driving coils and diodes 11 and 12 are provided respectively. The driving signal of the TR9 is at a low level during a period of T 1 +T 2 , while the driving signal of each of the TR10 is at a high level during a period of T 1 . During the period of T 1 , current flows through a power line VH, the TR9, the coils 2, the TRs 10 and the ground to rise. During the period of T 2 , the current flows through a closed loop comprising the TR9, the coils 2 and the diode 11, decreasing at the rate determined by the time constant of the closed loop. Thus, making the period of time of T 2  variable permits an actual falling waveform to be approximated to an ideal curve.

Filed: 1991-04-01
Abstract: PURPOSE:To prevent decomposition of thermal medium and deterioration of a heater by a method wherein each of a discharging pipe from an outlet port of a heater and a surface of the heater is provided with a temperature sensing means and a control mechanism is provided for controlling an amount of combustion of a burner in response to a difference in sensing temperatures of two sensing means. CONSTITUTION:As thermal medium within a heater 1 is rapidly evaporated and a thermal medium temperature at an upper part of the heater 1 is increased, a temperature of the second temperature sensing means 10 is increased, and in turn as a temperature difference exceeds a set value, an amount of combustion of a burner 8 is decreased. In this way, even if an amount of combustion of the burner 8 is decreased, the amount of combustion is decreased in a stepwise manner when the temperature difference is in its increasing tendency. A degree of rapid evaporation of the thermal medium within the heater 1 when a heating is energized is taken in response to a temperature difference between the two temperature sensing means 9 and 10, an amount of combustion of the burner 8 is increased or decreased, thereby a rapid evaporation of the thermal medium is restricted, a pressure loss within the heater 1 is reduced and a staying of gaseous thermal medium at the upper part in the heater 1 is reduced.

As the nozzle 16 moves, the end face cleaning nozzle 15 also moves in the same direction and jets an organic solvent upon the hardened resist from the inside of the recessed section 15a to clean the peripheral section of the end face of the substrate 11. The excessive amounts of the dissolved resist and solvent are removed by a vacuum removing section in the section 15a.

Title: Alarm transfer method between atm terminal station and atm terminal station adjacent device
Inventor: TOSAKA TAKUO
IPC: H04L12/26
Filed: 1998-03-18
Abstract: PROBLEM TO BE SOLVED: To allow a manager to detect failures, in a path which passes through the use of a different communication path by transmitting an alarm display signal in the direction of a transmission destination from an opposite side line of a line having a failure if a communication failure of ATM communication is supervised that directs from one ATM terminal station to the other ATM terminal station and detecting failures. SOLUTION: When an ATM terminal station adjacent device 1-4 detects the occurrence of a communication failure in the direction from a C point to a D point, it transmits an alarm display signal P-AIS in the direction of an E point of a communication pass path. An ATM terminal station 1-2 of a transmission destination receives the P-AIS and detects that the communication failure occurs. When a communication failure occurs in the direction from the D point to the C point, an ATM terminal device 1-1 of a transmission destination detects that the communication failure has occurred is a communication path and performs the same operation as the that in a reverse direction. The station 1-2 notifies the communication failure to the own management device, and a management device out of the own management range can grasp a communication failure between the C to D points.  Thus, necessary counter measures can be taken.

Title: Reproducer of disk recorder
Inventor: MIKI YUUJI
IPC: G11B19/02
Filed: 1983-04-19
Abstract: PURPOSE:To restart the reproduction when a power supply is recovered after a service interruption, etc. by making use of a fact that a turntable continues its revolution with no load immediately after a service interruption occurs and detecting presence or absence of the revolution of a motor after the power supply is recovered by means of an FG pulse to deliver the result of said detection to a microcomputer. CONSTITUTION:A motor 3 turns a turnatable 3a attached to a drive shaft and also outputs an FG pulse (d) by a generator provided to the drive shaft. A part of the pulse (d) is sent to a revolution detecting circuit 4 and at the same time sent back to a motor control circuit 2 to control the number of revolution of the motor. The pulse (d) is converted into the pulse voltage by a pulse voltage converting part 5 within the circuit 4. At the same time, the pulse voltage is counted for a fixed period of time by a counter 6 at a sampling time generating part 7. The counted pulse voltage is outputted to a microcomputer 1 in the form of a revolution output signal (e). Therefore the motor 3 has revolutions for several minutes with addition of the force of inertia of the table 3a since a brake mechanism has no actuation in case the power supply is cut off owing to a service interruption. When the power supply is recovered, the signal (e) is supplied to the computer 1 from the circuit 4. Then the reproduction is restarted at the present pickup position by the program of the computer 1.
