IPC: G11B5/73
Filed: 1989-06-16
Abstract: PURPOSE:To obtain the magnetic recording medium having reliability and excellent high-density digital recording and reproducing performance in combination by disposing a thin film of a ferromagnetic metal in which diagonally vapor deposited columnar fine particles and perpendicularly vapor deposited columnar fine particles are integrated on a substrate. CONSTITUTION:This recording medium is constituted by disposing the thin film of the ferromagnetic metal in which the columnar fine particles 2 consisting of the diagonally vapor deposited columnar fine particles and perpendicularly vapor deposited columnar fine particles are integrated on the substrate consisting of a high-polymer film 1. The ferromagnetical coupling among the columnar fine particles 2 is, therefore, weakened, unlike with an ordinary perpendicularly magnetized film. Noises are lowered and the higher C/N is obtd. A good error rate is obtd. in the high-density digital recording and reproducing; in addition, a lubricant intrudes in the spacings between the columnar particles 2 and the durability is improved. The magnetic recording medium for perpendicular magnetic recording having the high-density recording performance and the durability balanced at the high level is obtd. in this way.

Title: Developing roller
Inventor: MIMURA KAZUYOSHI
IPC: G03G15/08
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To obtain a developing roller which causes sufficient friction with toner to give enough charges and which prevents splitting of toner by controlling the microrubber hardness (A-method) of the developing roller to be within a specified range. SOLUTION: The microrubber hardness (A-method) of the developing roller 1 consisting of an elastic layer 3 and single or plural resin layers 4 on the elastic layer 3 concentrically formed around a conductive shaft 2 is controlled to 30 deg. to 55 deg.. The surface layer material used is not limited as far as the microrubber hardness of the roller is 30 deg. to 55 deg., and preferably 35 deg. to 55 deg. from the viewpoint to obtain good electrification of toner, and more preferably 35 deg. to 45 deg. from the viewpoint to prevent splitting of toner.

Title: Information device
Inventor: YOSHIMOTO KIYOUSUKE
IPC: G11B7/09
Filed: 1983-08-26
Abstract: PURPOSE:To prevent disturbance in a servo operation when a code signal is transferred to an information signal or vice versa by using a correction error signal obtained at a preceding information signal region as an input variable for feedback control at the region of a code signal. CONSTITUTION:Each output of a 2-division photodetector 11 is processed by a division circuit 18, becomes a correction error signal C of waveform as shown in Fig, H and inputted to a sample-and-hold circuit 21. Since an output in Fig. G is inputted to the circuit 21 from a code region detecting circuit 20, the circuit 21 outputs the correction error signal in response to said information signal region when no code signal region is detected and outputs a sample value of the correction error signal in response to the information signal region just before when said region is detected as shown in Fig. I. Thus, the correction error signal of the information signal region is inputted at all times even at the code signal region in a drive circuit and since the sample value of the correction error signal of the information signal region just before is inputted at said region, the rapid change in the operating control input and loop gain of an objective lens 4 is avoided.

Title: Lock current supplying method of pulse motor
Inventor: NAKATANI MAKOTO
IPC: H02P8/32
Filed: 1984-07-26
Abstract: PURPOSE:To suppress the fluctuation of a pulse motor rapidly by supplying an exciting current for locking with a current value larger than the exciting current value during operation. CONSTITUTION:A main controller 12 delivers a switching signal to a switch 19 at a timing when a rotation pulse motor 8 is locked to shift the switch as designated by a broken line to supply a reference voltage E from between resistors R1 and R2. Accordingly, the voltage E becomes a high voltage value to be supplied to an operational amplifier 18. In other words, when the motor is locked, a locking exciting current is increased larger than the exciting current during the operation of the pulse motor to generate a large torque to brake a rotational shaft fluctuated by the inertia to rapidly stop it.

Title: Pll oscillator and radio equipment provided with same
Inventor: SAGI YASUO
IPC: H04B1/40
Filed: 1991-06-27
Abstract: PURPOSE:To obtain the PLL oscillator in which noise attended with frequency division is reduced and the radio equipment provided with the PLL oscillator. CONSTITUTION:When a disconnection means 7 disconnects a phase locked loop, a voltage holding circuit 8 holds a control voltage fed to a voltage controlled oscillator 1 to a value just before the disconnection during loop disconnection. Thus, the voltage controlled oscillator 1 keeps the output of the oscillating frequency just before the disconnection of the phase lock loop even during the disconnection of the phase locked loop and since the phase locked loop is disconnected for the time, no noise attended with frequency division is included in the output of the voltage controlled oscillator 1. Thus, when the forming/ disconnection of the loop is repeated in this way, the noise quantity attended with frequency division included in the output of a PLL oscillator controlling the voltage controlled oscillator 1 is totally reduced. Furthermore, the PLL oscillator is employed for a reception section and a transmission section of the radio equipment while part of the oscillator is in use in common.
