IPC: H02M3/28
Filed: 1993-12-28
Abstract: PURPOSE:To reduce the sizes of a transformer and a choke coil by a method wherein a power for the flywheel diode of a first rectifying smoothing circuit is supplied by a second rectfying smoothing circuit. CONSTITUTION:A rectfying smoothing circuit 13 is composed of a rectifier diode 9, a flywheel diode 10, a choke coil 11 and a smoothing capacitor 12 and supplies a power to the flywheel diode 5 of a rectifying smoothing circuit 8. In a conventional example, an output voltage is applied in an off-period. To the contrary, in the circuit of the present invention, a voltage obtained by subtracting a voltage stabilized by the rectifying smoothing circuit 13 from the output voltage is applied. As the voltage-time product of the off-period is reduced, the voltage-time product of an on-period is also reduced. Therefore, a duty ratio can be reduced or a turn ratio can be reduced. With this constitution, a DC-DC converter which facilitates the miniaturization and the noise reduction can be obtained.

Title: Method of timming side of metal belt and continuous annealing facility
Inventor: FURUKAWA HOUHI
IPC: B23D19/06
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of troubles during side trimming. SOLUTION: A degree of contraction of a metal belt in a heat treating furnace in accordance with a read production instruction and a width contraction table which has been previously set (a2), the width of the metal band is measured (a3) and the width of the metal bank on the outlet side is estimated from the measured width and the degree of contraction. Then, the estimated width is compared with a desired width (a5), and side trimming is carried out if the estimated width exceeds the desired width.  A distance Lr from a welding point at a position where the width is unsatisfactory is determined if the estimated width is smaller than the desired width (a), and if the distance Lr exceeds a determination distance, the side trimming is interrupted from an intermediate position (a8), but if the distance Lr to the position where the width is unsatisfactory is less than the determination distance LO, the side trimming is interrupted from the head part of the metal belt (a9). Accordingly, there is no risk of carrying out side trimming at a position where the width is unsatisfactory, thereby it is possible to prevent occurrence of troubles during side trimming.

Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To detect a true stop empty state by providing first and second blades rubbing the surface of a reflector and an opening part in the second blade, for illuminating the reflector. SOLUTION: The first and second blades 40 and 42 in a blade part 38 rub the surface of the reflector, together with the rotation of a stirring plate 34. The first blade 40 is shorter than the second blade 42, so that the first blade 40 rubs the reflector together with the rotation of a rotary shaft 30 and then, the second blade 42 rubs the surface of the reflector with a delay of a specified time, to brush away toner on the reflector and to prevent the sticking of the toner on the surface of the reflector. The toner remaining in a toner supplying chamber is detected in such a manner that light emitted from a light emitting member passes through the inner opening part 43 of the second blade 42 and reaches the reflector and the reflected light is detected by a light receiving member.  At this time, the fact that the toner of the toner supplying chamber is reduced to a fixed level or below (stop empty state) is precisely detected and a user can be informed of the fact.

Title: Recording method for information
Inventor: MIYAUCHI YASUSHI
IPC: G11B7/30
Filed: 1990-11-30
Abstract: PURPOSE:To prevent a noise level from rising even when the rewriting of information is repeated many times by increasing the average irradiation energy near the central part of pulses forming recording marks. CONSTITUTION:The average irradiation energy near the central part of the pulses A, B which are going to form the recording marks is increased. Then, the temp. of the recording film irradiated with the central part of the recording pulses is maximized and the flow of the recording from the arc in the central part of the recording marks to the recordings on both sides arises at about the same extent if the rewriting is executed many times in this state. Since the position of the marks varies irregularly at every recording, the fluctuation in the thickness of the recording film is suppressed and the rise of the noise level is suppressed. Many times of the recording are possible in this way.
