Filed: 1985-09-11
Abstract: PURPOSE:To reduce a suction loss, by constituting a yarn end inside a spindle hole of a wooden bobbin for bobbin yarn so as to be drawn in by suction, after a lower opening of a suction nozzle comes nearer to an upper end part of the bobbin yarn. CONSTITUTION:When a suction nozzle 11 goes down by the drive of a driving cylinder, a side opening 11a of the suction nozzle and a suction duct 1 are interconnected to each other. And, a yarn end 10 inside a spindle hole of bobbin yarn 9 is drawn in the suction duct 1 via the suction nozzle 11. On the other hand, when the suction nozzle 11 goes up by the driving cylinder 6, its interconnection with the suction duct 1 is closed by a valve body by the side opening 11a of the suction nozzle and an inner wall surface 12b of a support cylinder 12. And, the yarn end of the bobbin yarn 9 drawn in the suction duct 1 is held between an edge part of the side opening 11a of the suction nozzle and the inner wall surface 12b of the support cylinder 12. Thus, since suction takes place with the nozzle 11 made to go down, a suction loss is little and suction efficiency is well improved.

Title: Image forming device
Inventor: IZUMIZAKI MASAMI
IPC: G03G15/00
Filed: 1991-07-18
Abstract: PURPOSE:To prevent fluctuations in a toner replenishing quantity caused by residual toner inside a toner replenishing tank. CONSTITUTION:An LED 80 is installed on one side surface at the prescribed position of the toner replenishing tank 60, and a photodiode 81 is installed on the corresponding other side surface. The toner replenishing tank 60 has sufficient toner 63 inside, and while the toner 63 is over the installation position of the LED 80, an output signal is not generated from the photodiode 81, to instruct that there is a large amount of the residual toner. On the other hand, when the residual toner is under the installation position of the LED 80, reduction in the residual toner is instructed with the output signal from the photodiode 81. When the number of video counts calculated from a picture signal is converted into a toner replenishing time, a conversion table for showing the correspondence relation of the number of the video counts in a CPU and the toner replenishing time, is changed according to the presence of the output signal from the photodiode 81, and the toner replenishing time corrected according to the residual toner is determined to replenish, the toner.

Title: Magnetoresistance magnetic head and its manufacture
Inventor: KATAKURA TORU
IPC: G11B5/39
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To realize supply of a sense current reliably only to a magnetoresistance layer by forming a magnetoresistance element by laminating a magnetoresistance layer, a non-magnetic insulating layer and a magnetoresistance stabilizing layer in this sequence. SOLUTION: In the MR head 1, the resistance change depending on signal magnetic field is output as a voltage change by supplying a constant sense current to a magnetoresistance layer 10 from a rear end electrode 6. In this case, since the magnetoresistance layer 10 of the magnetoresistance element 2 is formed in contact with the rear end electrode 6 on the rear end electrode 6 in this MR head 1, a sense current is supplied only to the magnetoresistive layer 10. Namely, since the rear end electrode 6 and the magnetoresistance stabilizing layer 12 are not in contact with each other in this MR head 1, the sense current is not supplied to the magnetoresistance layer 12, but only to the magnetoresistance layer 10.

Title: Magnetic recording medium
Inventor: MITAKE HIROSHI
IPC: C09D7/12
Filed: 1986-08-28
Abstract: PURPOSE:To improve durability without deteriorating magnetic characteristics and surface characteristic by dispersing fine activated clay powder adsorbed and occluded with a lubricating agent into a magnetic layer. CONSTITUTION:The lubricating agent is adsorbed and occluded into the pores on the surface of the fine activated clay powder and is dispersed into the magnetic layer. The lubricating agent is thereby migrated from the surface of the fine activated clay powder further into the magnetic layer and to the surface of the magnetic layer, by which the coefft. of friction on the surface of the magnetic layer is decreased and the excellent lubricity is obtd. The lubricating agent leaches gradually into the magnetic layer from the surface of the fine activated clay powder as the medium slides on a magnetic head; therefore, the lubricating effect is sustened for the longer time than in the case of dispersing the lubricating agent alone into the magnetic layer. The degradation in the lubricating effect and the deterioration in the properties of the coated film hardly arise even in the case of high compatibility between the lubricating agent and binder resin.

Title: Image recorder
Inventor: INOUE TAKAHIRO
IPC: B41J2/41
Filed: 1990-07-30
Abstract: PURPOSE:To prevent a coating beginning side where film thickness is thin from being used for a transfer material whose size is small by setting the carrying reference side of the transfer material as the coating end side of an OPC photosensitive body. CONSTITUTION:The film thickness is unstable and thin on the coating beginning side of the OPC photosensitive body 1 obtained by a dipping method, and then the film gradually has specified thickness. Since a potential is lower in a part where the film thickness is thin than a normal part, image density gets thinner. Then, the coating beginning part of the drum 1 is set on the right side, and the transfer materials 6 are fed so that their left ends all exist at the same position. Namely, the left side is set as reference, and the part where the film thickness is thin is not used for a B5 size or a postcard, which is smaller than an A4 size. Thus, the lowering of the image density and fogging caused by the abrasion of the photosensitive body and faulty cleaning caused by the abrasion of a blade are prevented.
