Patent JP-H03228221-A (JP)
Title: Manufacture of magnetic recording medium
Inventor: ITO YASUSHI
IPC: G11B5/84
Filed: 1990-02-01
Abstract: PURPOSE:To obtain uniform projection height of fillers by grinding the surface of a magnetic layer with fixed abrasive powder and then grinding this surface with isolated abrasive powder. CONSTITUTION:The surface of a magnetic layer 2 is finished to a flat surface without projections of fillers by grinding with using a fixed abrasive powder such as a lapping tape 6. This is because the fixed abrasive powder successively grinds downward from the top of fillers since the abrasive powder hardly reaches to the binder resin 5 or magnetic powder 3 among the fillers. Then the flat surface of the magnetic layer 2 is grinded with isolated abrasive powder 8. In this process, the abrasive powder intrudes among the fillers 4 to grind only the binder resin 5 and magnetic powder 3. Therefore, even when the isolated abrasive powder 8 collides with the filler 4, the filler is hardly grinded but remains, while only the binder resin 5 and magnetic powder 3 are removed. Thereby, the filler remains at uniform height which is determined by the grinding process with the fixed abrasive powder.

IPC: G05F3/30
Filed: 1987-01-30
Abstract: PURPOSE:To stably produce the normal reference voltage by using an inverter having input of the reference voltage and a transistor having its base voltage controlled by the output voltage of the inverter and connecting the emitter of the transistor to the positive phase input terminal of an operational amplifier. CONSTITUTION:The emitter of a transistor TR108 is connected to a positive phase input terminal of an operational amplifier 105 used by a reference voltage circuit by means of a CMOS inverter 10 where the output voltage approximates to the power supply voltage with the input voltage lower than the reference voltage level and the output voltage approximates to the earth voltage with the input voltage higher than the reference voltage level and the TR108 whose base voltage is controlled by the inverter output voltage. In such a constitution, the output voltage level of the amplifier 105 is forcibly raised to secure the normal feedback even in case the reference voltage drops when a power supply is applied or by some reason to turn off the TR100 and 101 inserted to a feedback circuit of the amplifier 105 and the application of the normal feedback is impossible to disable the recovery.

Abstract: PURPOSE:To prevent a paper cutter from interfering with a platen even when it is located on the upper side of the platen and clearly cut a recording paper, by enabling the paper cutter to be turned in conjunction with the movement of the platen. CONSTITUTION:When a lock lever 12 is pulled rightward under the condition where a platen cover 9 is closed together with a platen 27, the platen 27 and the cover 9 unlocked by the force of a torsion coil spring 29 are opened by turning clockwise through a support shaft 28. Since the platen 27 and the cover 29 are turned with separate shafts 29, 40 as respective centers, the turning paths of them are different. However, the difference between the turning paths is absorbed by a movement of a pin 39 within a slot 39a, so that the platen 27 and the cover 9 are turned in conjunction with each other. A projection 37 of the platen 27 is separated from the upper side of the tip of an arm 8c of a paper cutter 8, so that the cutter 8 is started opening by the force of a leaf spring 43. Accordingly, the paper cutter 8 and the platen 27 will not interfere with each other.
