Title: Rotary head device
Inventor: HASHI HIDEYUKI
IPC: G11B5/588
Filed: 1988-08-04
Abstract: PURPOSE:To prevent recording and reproducing performance from being lowered by rotating a rotary head so that a line to connect the magnetic gap part of the rotary head and the center of curvature in a thickness direction can be almost coincident to the normal of a surface, in which a tape and the rotary head contacts. CONSTITUTION:A lever 15 to be turned with a center 16 of the curvature in the thickness direction near the magnetic gap part of a rotary head 14 as a supporting point is operated by regulating pressure due to a compressive spring 17 with a cam 18 which is provided in a fixed cylinder 12. Since one edge 15a of the lever 15 is pressed and regulated to the cam 18 by the compressive spring 17, the lever is moved along the lift curved line of the cam 18 without backlash. Accordingly, when height of the cam 18 is gradually increased with the supporting point 16 as the center, the lever 15 is turned in a counter-clock- wise direction and when the height is gradually decreased, the lever is turned in a clockwise direction. Thus, a contacting condition with a tape 13 can be made satisfactory near the magnetic gap part of the rotary head and space loss can be kept at a minimum.

Title: Thin film magnetic head and its manufacture
Inventor: ITO MASARU
IPC: G11B5/31
Filed: 1985-09-03
Abstract: PURPOSE:To reduce the residual magnetization of a preceding signal caused by track deviation of a magnetic head caused between a recording and reproducing time by forming the cross section of an opposed magnetic substance as a trapezoid opposed to the short side. CONSTITUTION:The cross section of a lower magnetic pole 8 is formed trapezoidal and the cross section of an upper magnetic pole 9 is formed inverse- trapezoid. Thus, a recording and reproducing gap 10 formed between the lower magnetic pole 8 and the upper magnetic pole 9 is wider at both ends 11. When the recording and reproducing gap is large in general in the magnetic recording, no high density recording is desired, but the magnetic flux from the magnetic pole reaches remotely. Thus, in applying re-recording to the area recorded already, a signal is not recorded accurately at both ends 11 of the gap but the magnetic flux reaches the magnetic medium somewhat apart and the signal recorded already is reduced.

Title: Pulverized coal burner for forming reducing flame
Inventor: MORITA SHIGEKI
IPC: F23C99/00
Filed: 1982-11-09
Abstract: PURPOSE:To prevent dissipation of the heat generated in the vicinity of a burner throat through prevention of mixture of an internal peripheral air and an external peripheral air injected into a furnace and to reduce production of NOX without an increase in an unburnt content, by installing a sleeve of a refractory material, extending into a furnace, to the forward end of a duct for partitioning the internal and the external peripheral air mounted outside a pulverized coal conveying passage. CONSTITUTION:A trumpet-shaped sleeve 40, extending into a furnace and formed in a shape which widens toward the end, is located to the forward end on the furnace side of a duct 4 located outside a pulverized coal conveying passage 1. When combustion is effected by means of the pulverized coal burner so constituted which is employed in a burner for forming a reducing flame, the presence of the sleeve 40 prevents the mixture of the air injected into a furnace through an internal peripheral air passage 2 and an external peripheral air passage 3, whereby the heat in the vicinity of a burner throat can be prevented from dissipating, and the radiant heat from the sleeve can be effectively utilized. This enables a reducing flame, formed at a burner part, to be maintained at a high temperature, whereby improvement of firing may decrease production of a unburnt content and improves vaporization of an N-content in char, resulting in reduction in the amount of NO which is produced at an air combustion part at a rear flow resulting from the presence of a residual N-content.

Title: Power supply device
Inventor: HASEGAWA HIROSHI
IPC: H03K17/60
Filed: 1984-09-19
Abstract: PURPOSE:To prevent a switching means from malfunction by forming a voltage setting means for setting up the 1st output voltage value of a switching means higher than the 2nd output voltage value to make an output voltage reach the 2nd output voltage value without fail after making it pass the 1st output voltage value when the output voltage of the switching means is reduced. CONSTITUTION:Since a transistor (TR) Tr6 is turned on by opening a switch S, a reset output is turned to 'L' and a counter consisting of flip flops FF1-FFN starts to count up clock pulses outputted from an oscillator (OSC). Since base current is supplied to a TR Tr3 by charge left in a capacitor compo nent included in an exposing meter circuit Me or the like through a resistor R4, the Tr3 is turned on to discharge the residual charge in the circuit Me by a resistor R3 connected to its collector with a comparatively small time constant. Since the FF1-FFN are still connected to a line connecting the TR1 with the circuit Me, supply voltage El to the FF1-FFN is also dropped at the same speed as that of the circuit Me.
