Title: Motor driving device, adjusting method therefor, and information storage device
Inventor: NISHIDA MASATSUGU
IPC: H02P29/00
Filed: 1999-02-19
Abstract: PROBLEM TO BE SOLVED: To adjust an offset so that a dead band is automatically minimized by detecting a comparison signal, while an indicated value is varied and setting the zero level of the indicated value based on variation in comparison signal. SOLUTION: It is determined whether pwm0=0 (S1-7). When with pwm0=0, a DTCR register is already at '1', that is the output signal from a current sense circuit is lower than a target current indication signal and a drive signal DRVON is brought to 'high' level, a first control signal *EN is brought to 'low' level to actuate PWM drive. That is when a voice coil motor is driven in this state as is, since the operation of the voice coil motor becomes unstable, errors are dealt with (S1-8). If pwm0 is not 0 (S1-7), it is determined that the amount of offset has been detected as being normal, a target current indication signal immediately before the output of a comparison circuit raises to '1', that is pwm0=0 (pwm0-A) is calculated (S1-9), and the calculated pwm0 is stored as the amount of offset in a memory (S1-10).

Title: Gas flow quantity controlling unit
Inventor: IGARASHI ITSUO
IPC: F23N1/00
Filed: 1984-03-07
Abstract: PURPOSE:To prevent erroneous changeover of a master burner to an auxiliary burner from occurring when the thermal power of the master burner is adjusted by affording a resistance to the operation of a controller pin in accordance with the position of the minimum gas flow quantity of the master burner, and emitting a metallic sound when the gas flow quantity exceeds the resistance value. CONSTITUTION:In a gas table or the like, a range up to a certain angle of a controller pin 10 is a thermal power adjusting range. At this point, only the hole diameter for the minimum flow quantity of a controller plate 12 is on the pass port of a controller packing 11, and the master burner carries out a turn-down combustion. At this position, the projection of a leaf spring 21 comes into abutment with the projection of a controller base 19 and gives a resistance to the operation of the controller pin 10. When the controller pin 10 is rotated against the resistance, the pass hole of the controller plate 12 slips off from the pass port of the controller packing 11 to stop the supply of the gas. As a result, the master burner is put out, and changeover to the combustion of the auxiliary burner 3 alone is carried out. Upon this occasion, the leaf spring 21 rides over the projection of the controller base. The end surface of the leaf spring 21 comes into collision with the projection 17a of a cover 17 to generate a sound.

Title: Switching system
Inventor: YAMAMOTO KAZUHIRO
IPC: H04B1/74
Filed: 1983-03-16
Abstract: PURPOSE:To attain an assured circuit switching system which is free from a malfunction due to an interference between both polarized waves, by using a circuit identification code means and a switching means. CONSTITUTION:It is supposed that a transmission part 102-1 of the 1st using circuit has a fault and the transmission output is cut off. Under such conditions, it is impossible to detect a frame pulse at a received signal processing part 202-1 although a reception part 201-1 of the 1st circuit receives an H polarized wave of the 2nd circuit owing to a polarized wave interference for example. Thus the system frame synchronism is lost, which is immediately identified at a circuit switch control part 206. As a result, the part 206 transmits immediately a circuit switch signal and gives a command to a spare set of the reception side to relieve the 1st circuit side. At the same time, a command is given to a circuit switch control part 106 of the transmission side 1 to relieve the 1st circuit side through a spare set of the transmission side. The part 106 immediately executes this relief. Therefore the signal of the 1st circuit is transmitted by means of a spare set both at the transmission side 1 and the reception side 2.
