Title: Writing circuit for magnetic recording medium
Inventor: NAGAYAMA YOSHIHARU
IPC: G11B5/09
Filed: 1983-05-11
Abstract: PURPOSE:To secure the large voltage amplitude of a coil of a magnetic head with a simple constitution and at the same time to prevent assuredly the saturation of a drive current control transistor, by providing a clamping circuit to prevent the saturation of a transistor which controls the coil drive current of a magnetic head. CONSTITUTION:The drive current of a coil L of a writing magnetic head is controlled by transistors TRQ1-Q4 to increase the writing voltage amplitude. Zener diodes Z1 and Z2 constituting a clamping circuit are connected to both ends of the coil L. Thus the voltage of the junctures between the TRQ1-Q4 and the coil L is clamped to the potential obtained immediately before the collector-emitter voltage of TRQ1-Q4 is saturated respectively. Thus the saturation is avoided for the TRQ1-Q4. As a result, the voltage amplitude of the coil of the magnetic head is kept large with a simple constitution. Then the saturation is assuredly prevented for a coil drive current control TR. Thus it is possible to perform the writing of data at a high speed and with high density.

Title: Method and device for continuous annealing
Inventor: OKAYA TAKUYA
IPC: C21D1/00
Filed: 1982-05-12
Abstract: PURPOSE:To prevent the decrease in the thermal efficiency of an annealing furnace by cooling of carriages in a continuous annealing furnace wherein plural carriages for carrying products to be annealed are moved by moving the carriages which end annealing immediately from the outlet to the inlet of the furnace. CONSTITUTION:Plural carriages 1-9 carrying products to be annealed are moved in an arrow 12 direction to anneal said products in a continuous annealing furnace provided with an inlet chamber 14, an outlet chamber 13 and adjacent chambers 15 for traveling of the carriages. The preceding carriage 1 which ends the annealing is drawn out into the chamber 13. The products completed of the annealing are unloaded from the carriage and the products to be annealed are loaded thereon, then the carriage is moved in the direction of an arrow 16 by a traverser moving in the direction at a right angle to the advancing direction of the carriage. The carriage is transported by a transport car 17 into the chamber 15 to the inside of the chamber 14. In succession, the carriage is pushed through the inside of the chamber 14 in the direction of an arrow 12 from the inlet of the annealing furnace by another traverser. The time since the carriage goes out into he chamber 13 until it enters the furnace again through the inlet chamber is just a few minutes and since the degree at which the carriage 1 is cooled is small, the decrease in the thermal efficiency of the annealing furnace owing to the temp. drop of the circulating carriage is extremely small.

Filed: 1980-06-16
Abstract: PURPOSE:To accomplish accurate measurement of both gray and colored bodies by correcting a gray body radiation factor obtained in combination of data on two effective wavelengths appropriately selected from among more than two of thsoe given by the spectroscope of radiation flux from object initially being measured. CONSTITUTION:Transmitting elements 21a and 21b output ratios 32a and 35b in combination of those on two colors selected from measured data 32c-32e on three effective wavelengths lambda1-lambda3 given by the spectroscope of radiation flux from an object initially being measured. A transmitting element 22a calculates an average temperature from the ratios 35a and 35b. Transmitting elements 23a-23c out put spectroscopic radiation factors 25b and 25d from the average temperature and the data 32c-32e respectively. An initial value 37 is inputted into a transmitting element 26a which outputs ratio 39 of spectroscopic radiation after the spectroscopic radiation factor or the initial value is selected by a control signal 38 from an identification control element 24a corrsponding to a process 24. In this manner, based on an assumed value of the ratio 39 improved operation is returned to the elements 21a and 21b. This will be continued until an accurate temperature and spectroscopic factor are found.

Abstract: PURPOSE:To quickly and easily correct a tilted subject into an erect image while looking at the subject image on a monitor TV and observing said erect image by attaching a camera main body to an attachment gear and rotating this gear by a motor via a decelerating revolution means to turn the camera main body by remote control. CONSTITUTION:An erect subject is usually obtained and the image of the subject picked up by a solid-state image pickup element 10 through a lens part 33 is projected on a monitor TV as an erect image. In case the subject is tilted to the right or the left, a decelerating motor 22 is rotated by monitor control in the correcting direction against the tilting direction of the subject while looking at the subject image projected on the monitor TV. Then the revolution of the motor 22 is stopped when the erect subject image is obtained. In this case, if a solid-state image pickup element 11 is turned to the right or the left by 90 deg. from the revolving neutral position, a limit switch 29 is actuated by a hook part 25a and the drive of the motor 22 is automatically stopped by the switch signal. At the same time, a detecting projection part 25b is detected by a photosensor 27 for decision whether the element 11 is kept at the revolving neutral position or not.

Abstract: PURPOSE: To make it possible to apply even signals of a band with an unstable frequency interval, by removing a fixed number of following pulses from the point in time when the number of pulses obtained by a SAW (elastic surface wave) element reaches a fixed value.  
     CONSTITUTION: Once the local oscillation signal of electronic tuner 1 is swept, a pulse is generated, at every frequency of 2MHz of the local oscillation signal, by SAW element 2,detecting amplifier circuit 3 and waveform shaping circuit 4. When a frequency interval between channels is 6MHz, the output of SAW element 2 is divided by three and counted by counter 7, whose output data becomes a channel number. In addition, once the frequency interval becomes 10MHz, 10-detection circuit 16 operates to remove the unneeded component of the output of SAW element 2 and when the number reaches a fixed value, 12-detection circuit 17 returns its original operation, so that the data of counter 7 will be prevented from differring with the channel number.

Title: Composite magnetoresistance effect element
Inventor: KITADA MASAHIRO
IPC: H01L43/08
Filed: 1985-04-19
Abstract: PURPOSE:To improve electromagnetic characteristics by using an amorphous thin film as a bias of an alloy thin film. CONSTITUTION:Before a permalloy film is directly formed on a substrate, a different kind of material is evaporated or sputtered. The permalloy film is continuously evaporated on the material. Then reaction with the substrate is suppressed, and the deterioration of the permalloy film becomes less. The coercive force of the permalloy film is more increased as the film comes closer to the substrate. Especially in the vicinity of the substrate, the coercive force becomes high rapidly. The decrease in the characteristics in the depth direction of the permalloy as obserbed in the coercive forcen can be also found similar in the magnetoresistance effect rate of the permalloy film. The rate is decreased as the film comes closer to the substrate. Thus, the uniform film can be formed with respect to the depth direction of the electromagnetic characteristics of the very thin permalloy film.
