Title: Servo signal setting system for magnetic disk
Inventor: NOKINA KIMIYA
IPC: G11B21/10
Filed: 1991-10-30
Abstract: PURPOSE:To set a servo signal between inner and outer circumferential stoppers provided at an HDA by a servo writer with respect to the magnetic disk of a head disk assembly(HDA). CONSTITUTION:By a bias current, the internal carriage mechanism of HDA is driven, a turning piece 41 is brought into contact with one side of inner circumferential or outer circumferential stoppers 42a and 42b, and a testing signal is written by a head 31. An external carriage mechanism 5 of the servo writer is operated, the seek movement is performed by an induction pin 53 of a driving arm 52 to the head and the test signal is read. The position of an arm at the position where the voltage is a little lower than a normal value is measured by a laser length measuring machine 54, and the measured value is stored into a memory 62 as the position data of one side stopper. During the movement of an internal carriage mechanism, the position of the driving arm is measured by the laser length measuring machine, and the measured value stable to the constant value is stored in the memory as the position data of the other side stopper. Both position data are referred to, and between inner and outer circumfernetial stoppers 42a and 42b, the servo signal is set.

Title: Production of substrate for optical element
Inventor: HONMO HIROSHI
IPC: B21D28/14
Filed: 1992-11-20
Abstract: PURPOSE:To allow formation of micro-bonding bumps having similar profile and weight with high reproducibility. CONSTITUTION:A ribbon type AuSn foil 3 of 50mum thick is inserted between a super steel micro-punch 1 having outer diameter of 50mum and a stainless steel die 2 having large hole diameter of 100mum and small hole diameter of 60mum. Since the hole of the die 2 becomes narrower toward the outlet, central axis of the micro-punch is aligned forcibly with that of the hole of the die 2 as the micro-punch 1 is driven into the hole of the die 2 even if the central axes of the micro-punch 1 and the hole of the die 2 are initially shifted thus punching the AuSn foil 3 onto the surface of an Au pad 5 having diameter of 60mum formed on the Si substrate 4. This arrangement allows formation of micro-bonding bumps having similar profile and weight with high reproducibility.

Title: Constant voltage circuit
Inventor: TSUKAHARA MASAHIRO
IPC: G05F3/24
Filed: 1989-11-30
Abstract: PURPOSE:To obtain the constant current effect without increasing the power consumption of a constant voltage circuit itself by cancelling the temperature change of the resistance between the base and the emitter of a transistor TR and that of a load resistance. CONSTITUTION:A current is supplied to a resistance R5 made of a poly silicon, whose temperature coefficient is negative, through a TR Q4. A constant voltage Vout applied to the base of the TR Q4 through a resistance R0 is applied to a TR Q3 through a resistance R4. When the temperature rises, the voltage Vout as the output of a TR Q1 is reduced because the voltage drop between the base and the emitter of a TR Q5 is reduced to raise the collector voltage of a TR Q2. Thus, the temperature characteristic of the resistance R5 is cancelled to keep a current Iout constant.
