Title: Thin film magnetic head
Inventor: KOYANAGI TSUTOMU
IPC: G11B5/31
Filed: 1989-06-08
Abstract: PURPOSE:To obtain the thin film magnetic head having stable magnetic characteristics by providing insulating packing films which descend and incline from the side of a pole part toward a base body side in corner parts formed of the side faces of the pole part and the surface of a base body and eliminating the deposition of the metal to the periphery of the pole part. CONSTITUTION:The insulating packing films 12, 13 are packed in the angle parts formed of the side surfaces 211, 212 in the pole part 21 which is not coated with an org. insulating film 6 and the surface of the base body 1 so as to fill the steps thereof. The insulating packing films 12, 13 have slopes 121, 131 descending and inclining from the pole part 21 side toward the base body 1 side. The shadowing of the pole part 21 is obviated at the time of removing the unnecessary part of the underlying conductor film by ion milling if such packing films 12, 13 exist. The Ar<+> ions at the time of the milling act directly on the underlying conductor film existing on the slopes 121, 131 positioned in the side parts of the pole part 21. The sticking of the metallic component constituting the underlying conductor film on the side faces of the pole part 21 and the periphery thereof is obviated in this way.

Title: Timer system for virtual computer system
Inventor: OMINATO TAKESHI
IPC: G06F1/14
Filed: 1995-06-13
Abstract: PURPOSE: To improve the timer interruption processing performance of a guest in a virtual computer system. CONSTITUTION: A CU 101 controls the operation of every part, and a TOD 102 undergoes addition of +1 by an adder 103 at a fixed interval for clocking of the present time. A CKC 104 holds the clock comparator value (CKC) of a host or guest. A comparator 105 compares the value of the TOD 102 with the value of the CKC 105 and transmits a CKC interruption. A CPT 106 holds the CPU timer value (CPT) of the host or guest. When the value (CPT) undergoes subtraction of -1 by a subtracter 107 at a fixed interval and becomes negative, the CPT 106 transmits a CPT interruption. An SCPT 108 holds the CKC or CPT of the host under the control of a VM. When the CKC or CPT undergoes subtraction of -1 by a subtracter 109 at a fixed interval and becomes negative, the SCPT 108 transmits a host CKC or CPT interruption. Then the CKC 104 and the CPT 106 are monopolized by the guest under the control of the VM.

Filed: 1990-06-04
Abstract: PURPOSE:To make printable dot density variable responding to data being the material to be printed by modulating optical beam, and varying rotation speed of a photosensitive body drum and temperature of fixing. CONSTITUTION:When printing with a high dot density is instructed by a host computer H or a panel 26, the rotation speed of a motor 20 which drives resist rollers 5 and 5, the photosensitive body drum 6, and rollers 8 and 10 of a fixing device 11 is made slower than normal by a microcomputer 21. Next, when printing data is inputted, the light beam is modulated and the drum 6 is irradiated by an optical writing device 12. Because the drum 6 is rotated at a slower speed than normal, no change in writing density is accepted but recording paper ejected from the drum 6 where the recording density in a sub scanning direction is made more dense is entered into the fixing device 11 and is heated at a lower temperature than in the normal state but since the rotation speed of the rollers 8 and 10 is lowered, the imparted energy is equal to that at a normal time. Therefore, the toner is not overheated and can be foxed onto the recording paper in the best state.

Filed: 1977-12-07
Abstract: PURPOSE:To make it possible to obtain a gain-improved linear amplifier circuit by enabling the circuit Vth (thereshold voltage) to vary following up an input DC level. CONSTITUTION:Regarding input V+ as the reference voltage of circuit Vth (threshold voltage) compensating circuit 4, the drain potential of transistor Tr Tr7 of differential amplifier 1 falls as the potential of V+ (=V-) rises and, in consequence, input bias voltage V01 of linear amplifier 2 decreases, so that amplifier 2 can be operated in the highest-gain region by lowering the DC level of output O1 of amplifier 2. Namely, in the case V+ (=V-) is increased, the drain potential of Tr Tr13 increases corresponding to the rise so as to lower the ON resistance of Tr Tr17, circuit Vth of linear amplifier 21 decreases, and at this time, Tr Tr4 and Tr5 become close to cut-off states to decrease Vo11, so that am plifier 21 will amplify the input at the maximum gain. Linear amplifier 22 at the next stage operates in the same way.
