Title: Rolling method by rolling mill provided with split roll for adjusting deflection of work roll
Inventor: KOBAYASHI YASUO
IPC: B21B1/22
Filed: 1984-05-15
Abstract: PURPOSE:To prevent uneven wear and to eliminate roll marks and difference in brightness of a rolling material by moving axially the supporting rolls of a rolling mechanism which supports work rolls of a 4-stage rolling mill by the one- side supporting rolls to be subjected to a deflection adjustment by split rolls. CONSTITUTION:The work rolls 1 of the 4-stage rolling mill are given pressure by backup rolls 2 and are supported by the one-side supporting rolls 3 to be subjected to the deflection adjustment by the plural split rolls 4. The rolls 3 are axially slided, by which the partial uneven wear 3' by the working faces of the rolls 3 with the rolls 4 is prevented. The transfer of the wear to the rolls 1 is thus obviated and the difference in the brightness of the rolling material 5 owing to the partial rough surfaces of the work rolls 1 is prevented without generating roll marks on said material.

Title: Soldering iron
Inventor: MATSUZAWA TAIRA
IPC: B23K3/02
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To facilitate the recovery of temperature even when the temp. of an iron tip is lowered and to reduce the effect of surrounding temp. by arranging a cover for covering the outer periphery of a heater pipe and a means for fastening the cover. SOLUTION: A cover 20 is fitted to the neck part 14 of a soldering iron body 1 with a hose band 21. The cover 20 is made of metal and bent to a cylinder and the tip part is contracted. The cover 20 covers the outer periphery of the heater pipe 12 and part of the iron tip 11 is exposed. Since the heater pipe 12 is not in contact with outer air, the effect of outer air is eliminated and the temp. of the iron tip 11 is stabilized. Since the cover 20 can freely be fitted/removed, the cover can be fitted to various kinds of the soldering irons. Even if the soldering iron is dropped, the cover 20 is hit first, and hence the soldering iron 11 is hardly bent. Since the temp. variation is small, the service life of a ceramic heater is extended and the power consumption is reduced.

IPC: B65H29/70
Filed: 1989-04-18
Abstract: PURPOSE:To keep a predetermined distance between an ink discharge surface of a recording head and a surface of a recording medium by a method wherein pinch rollers are constructed so as to generate tensile forces acting on the recording medium outward from the center in the feed direction thereof along the recording medium. CONSTITUTION:Pinch rollers 11A and 11B are provided on the both ends of a roller shaft 12. The left roller 11A and the right roller 11B are spirally formed respectively in right hand winding and left hand winding with the same pitch. When a recording medium 5 held between a platen roller 4 and a presser spring 6 reaches a position of a rubber roller 7, the recording medium 5 is depressed to the roller 7 by the rollers 11A, 11B to be applied with a feed force in a su-scanning direction. At this time, the recording medium 5 is applied with forces acting symmetrically outward from the center of the roller shaft 12 with the same magnitude by the rollers 11A, 11B. These forces absorb the expansion of the recording medium 5 after recording, thus preventing a waviness phenomenon. Therefore, the recording medium 5 is prevented from coming into contact with an ink discharge surface of a recording head 1.

Title: Output control of dc-dc converter corresponding to fluctuation in switching frequency
Inventor: ADRAGNA CLAUDIO
IPC: H02M3/335
Filed: 1998-04-09
Abstract: PROBLEM TO BE SOLVED: To make the output of a DC/DC converter constant by clamping an error amplifier output signal of a control circuit to a voltage proportional to the amplitude of DC signals inversely proportional to the frequency or by giving an offset equal to a voltage difference between a constant voltage and DC signal to a signal occurred in a current sensing resistor. SOLUTION: A sawtooth wave signal generated by an oscillator is detected by a capacitor Cosc of an RC group. A process of generating a DC signal having an amplitude inversely proportional to that frequency, a process of clamping an error amplifier E/A output voltage to a voltage having an amplitude proportional to the amplitude of the DC signal, or a process of off-setting a signal in a current sensing resistor by a voltage, corresponding to the difference between the constant voltage and DC signal is carried out. By doing this, it becomes possible to obtain a method and a compensating circuit which can be easily realized independently of the characteristics of synchronous signal controlling the switching frequency, and can make the output power of a converter constant against the changes in switching frequency.
