Title: Magnetic recording medium
Inventor: SATO NOBUO
IPC: G11B5/72
Filed: 1987-04-07
Abstract: PURPOSE:To obtain good image quality at the time of still reproduction under low humidity by forming a thin layer contg. a specific phenyl fluoride deriv. on a thin ferromagnetic metallic film into which oxygen is incorporated. CONSTITUTION:The thin layer 3 contg. the phenyl fluoride deriv. expressed by formula I is formed on the thin ferromagnetic metallic film contg. oxygen. In formula I, (n) denotes 0-10 integer; (m) denotes 0 or 1 integer; A denotes a polar group having the atom of any among oxygen, nitrogen, sulfur and phosphorus at its bond terminal. The stable still reproduction durability is thus maintained in the low humidity environment where the adhesion of the ferromagnetic metal to a magnetic head is liable to arise, by the powerful effect of protecting the surface of the ferromagnetic metal and lubricating the same possessed by the phenyl fluoride deriv. under low humidity.

IPC: H01L29/78
Filed: 1990-03-30
Abstract: PURPOSE:To improve throughput of a manufacture process by radiating laser light after forming a reflection preventing film whose thickness is different from that of a treated body.

Inventor: SAKAGUCHI MITSUTO
IPC: B41J3/00
Filed: 1978-07-12
Abstract: PURPOSE: To provide high speed recording by means of a low output laser lay by irradiating the laser lay on a continuous thin film on which opaque particles are stuck, then removing the particles from a base plate and transfering them on to a medium which is located close to the base plate.  
     CONSTITUTION: A printing ribbon and a medium 5 are continuously moved in an arrowed direction, while a transparent conductive film 2 is grounded, and a positive voltage and a negative voltage are applied to a charger and an electrode plate 7 respectively. All particles 4 on the printing ribbon are charged when they pass through the charger 6, and are transfered below the electrode plate 7. When a thin film 3 is irradiated by a laser lay 9, the area of the film where the lay has hit is evaporated and the particles 4 in that ares become free, thus they are transfered and are stuck on the medium 5 by means of coulomb force. The particles 4b are stabilized by heat from a heating unit 8 and are fixed on the medium 5. The laser lay 8 is controlled depending on recording information; and as it scans a paper vertically, a vertical dotted line can be recorded by a single scanning. A dotted image is recorded in conjunction with the successive motion of the printing ribbon and the medium 5.

Abstract: PURPOSE:To reduce an error in measurement caused when a frequency tracking unit is incapable of tracking, by inputting to a pulse counter the output of a V-F transducer which is held in and output to an output frequency of a frequency divider just before the lock-off of the frequency tracking unit. CONSTITUTION:When a frequency tracking unit 9 is in the lock-off state, a latch circuit is put in a latching state by a lock-off signal of a lock-on detector 18. Therefore an F-V transducer 15a outputs, in a holding manner, an analog voltage being proportional to an output frequency of a frequency divider 10 just before the lock-off of the tracking unit 9. Accordingly, the output of a V-F transducer 17 is signal obtained by holding a frequency equal to the output frequency of the frequency divider 10 just before the lock-off. The output pulse of the frequency divider 10 and the output pulse of the transducer 17 are switched over by a lock-on signal of the detector 18 so that the former be used on the occasion of lock-on and the latter on the occasion of lock-off as a length measurement pulse respectively, and thereby an error in measurement occurring on the occasion of lock-off can be reduced. Since the moving speed V of an object 1 does not change sharply, the error is with in a negligible measurement scope in regard to the lock-off in a short time.

Filed: 1992-03-09
Abstract: PURPOSE:To reduce residual magnetization on a cathode ray tube by switching a direction of a resonance current in 1st and 2nd resonance circuits alternately so as to improve unbalance of a positive/negative level of a resonance current. CONSTITUTION:When changeover switches 3a, 3b are thrown to the position of a fixed contact, a resonance current flows in a capacitor 2a, the changeover switch 3a and a degaussing coil by the discharge of a 1st capacitor 2a having been charged from a DC power supply. The 2nd capacitor 2b is charged for that time. When the changeover switches 3a, 3b are thrown to the opposite fixed contact, a low level resonance current flows in the capacitor 2b, the changeover switch 3b and the degaussing coil 1 by the discharge of the 2nd capacitor 2b in opposite polarity. As a result, the resonance current with excellent balance in the polarity as a whole is fed to the degaussing coil 1 while being in attenuation vibration and the cathode ray tube is efficiently degaussed by a well balanced magnetic field from the degaussing coil 1.
