Title: Magnetic recorder
Inventor: NAGAOKA HIDEO
IPC: G11B5/027
Filed: 1985-03-01
Abstract: PURPOSE:To improve the after-recording capacity by providing a means which stops the operating of an erasing head, amplifies an output signal of a mixing means, records the second input signal on a magnetic tape by the first sound head and supplies the output signal of the mixing means to a monitor. CONSTITUTION:At the after-recording time, an old signal recorded on a tape 27 is reproduced by sound heads 21 and 22 and passes P sides of switches S23 and S24 and is supplied to a recording/reproducing amplifier 29, and the amplified signal is supplied to a delay line 32. When a superposing signal to be recorded newly is impressed to a signal input terminal 34, this signal passes the A side of a switch S27 and is applied to a mixer 33. The old signal which passes the delay line 32 is impressed to the mixer 33 and is mixed with the superposing signal to become a synthetic signal, and this synthetic signal is impressed to a recording/reproducing amplifier 31 through the A side of a switch S28 and is amplified by the amplifier 31 and is supplied to sound heads 25 and 26 through P sides of switches S25 and S26 and is not only recorded on the magnetic tape 27 but also supplied to a monitor 30.

Abstract: PROBLEM TO BE SOLVED: To provide an ink jet recorder having a long life, simple structure and low cost by extending a selecting range of ink to be used. SOLUTION: Blades 3 in an ink cartridge 1 are rotated by a motor in a direction of an arrow, and hence ink 2 is rotated in the cartridge 1. At this time, a magnetized leaf spring 4 is brought into close contact with an inner wall of the cartridge 1 to block the small hole 5 at a side of the cartridge 1, and hence the ink 2 is not externally leaked. An ink discharging electromagnet head 6 is magnetized corresponding to a record signal, and then the spring 4 magnetized in the same polarity at an inner surface of the cartridge 1 is raised. At this time, the ink 2 is discharged from the hole 5 by a centrifugal force. The discharged ink 2 is adhered to a recording sheet to complete printing.

IPC: C03B1/00
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To decrease seed (bubbles having <1 mm diameter) and blister (bubbles having >=1 mm diameter) in a fused glass. SOLUTION: In the glass, iron is mixed by >=0.27 wt.%, preferably >=0.28 wt.% expressed in terms of ferric oxide. In the producing method of the glass by fusing a glass raw material in a fusing oven, one prepared by mixing >=0.27 wt.%, preferably >=0.28wt.% iron expressed in terms of ferric oxide is fused in the fusing oven. It was found that the seed and the blister in the fused gl-ass are decreased by blending the larger quantity of iron than that in the case of a common amber glass.
