Title: Magnetic recorder
Inventor: YAMASHITA KEITAROU
IPC: H04N5/7826
Filed: 1977-12-20
Abstract: PURPOSE: To obviate the occurrence of stepwise differences between heads at the recording by detecting the recording track of one head at the first of recording and determining the scanning tracks of other head in a VTR of helical scan type.  
     CONSTITUTION: Video signal Sy is made to FM signal SF which is then supplied to the recording side contacts R of recording-reproducing changeover switches 21A, 21B. At the recording, the recording track of one head 22A is detected in the initial stage of recording, thereby the scanning truck of the other head 22B is determined. Because of this, the head 22B roughly follows the track having been recorded with the head 22A in the previous field and scanning is performed under application of vibrations. At the time when the head 22B ends scanning of 1 field, the center of the scanning track of the head 22B and the center of the track recorded with the head 22A align. Thereby, the track pitch at the recording is accurately determined and good recording accomplished even in such a case when a stepwise difference occurs between the heads owing to the residual distortion, etc. at the reproducing.

Abstract: PURPOSE:To improve the operation efficiency by a method wherein a door is forced to move in the opening direction by an enforcing device after a releasing device is released by a signal from a timer when cooking finishes and gradually and automatically opened by the action of a damper which works only when the door is opened. CONSTITUTION:When a cooking time period is set by timer setting buttons 49 and 50 and a start button 32 is pressed after food to be cooked is placed in a housing compartment 22 and a door 32 is closed, a electromagnetic wave element 23 is put in action to cook the food. The time period indicated on an indicating panel 51 is reduced as time passes and when it reaches the set time, a magnet 47 is energized by a signal from a timer. When energized, the magnet 47 attracts a metallic member 48 causing an arm 26 to move down and a claw 44 to come off from a latch main body 24. When the claw 44 comes off from the latch main body 24, the magnet 47 is deenergized. At this moment, a door is opened by an action of a coil spring 35 which is attached around a pivot 33 and forces the door to move in the opening direction.

Abstract: PURPOSE:To shorten a dwell time for tappet depression at the time of its setting as well as to make improvements in setting efficiency, by sealing a high pressure chamber of a hydraulic tappet with the oil whose viscosity is lower than that of engine oil, and spaces other than that with the oil whose viscosity is higher than that of the high pressure chamber. CONSTITUTION:At the time of setting a hydraulic tappet serving as a fulcrum for a rocker arm 10, a cylinder 1 is fitted in a hole and then such oil as being lower in viscosity than that of engine oil is put in, and a piston 2 with a check valve 3 is depressed and fitted therein. At this time, the said oil in a high pressure chamber 6 is removed from a minute clearance between the piston 2 and the cylinder 1, whereby the piston 2 is depressed to the extent of the specified position. Since the oil in the high pressure chamber 6 is small in viscosity, drain time of this oil is short enough. After setting operation is over, such oil as engine oil or the like being higher in viscosity than that in the said higher pressure chamber is taken in, and an engine is operated, setting is completed.

Title: Yoke type thin film magnetic head
Inventor: KUDO ICHIRO
IPC: G11B5/39
Filed: 1987-06-19
Abstract: PURPOSE:To prevent the Barkhausen noise and to prevent peeling of a front yoke by forming the front yoke and a back yoke with bulk material, and cutting them into thin films and arranging a thin film MR element between them. CONSTITUTION:A front yoke 13 and a back yoke 14 are formed on a substrate 11 by bulk material like an Ni-Zn-ferrite and are cut into thin films. A thin film MR element 16 is arranged between yokes 13 and 14 so that it is electrically insulated but magnetically coupled. Since yokes 13 and 14 are formed with bulk material, the surface state is satisfactory and a magnetic barrier is difficult to occur, and the Barkhausen noise is prevented. Since the front yoke 13 is completely a thin film, it is prevented from peeling and wearing due to run of a magnetic tape 21.
