Title: Weak coupling oscillator utilizing multi-stage moving average processing
Inventor: UJIIE HITOSHI
IPC: H03L7/113
Filed: 1993-02-02
Abstract: PURPOSE:To remarkably reduce a time required for an output signal synchronously with a reference signal by executing average processing while switching dynamically a time constant from a small value to a large value sequentially in response to the lock state of the synchronization system. CONSTITUTION:A phase difference between a signal fin and an output signal fout of a reference oscillator 11 is detected by a DPC 12 and the phase difference is fed to a 1st averaging circuit 13-1 having a comparatively shorter (smaller) time constant, in which rough phase data are detected by simple average processing. A switch circuit 14 is set to select at first an output of the circuit 13-1 and the selected signal is fed to a proportion integration circuit 16. The oscillated frequency of a VCO 18 is highly stable synchronously with a signal from the reference oscillator by the action of a PLL. A threshold level used to make comparison with phase data corresponding to each averaging circuit is stored in the switch control circuit 15, and when the threshold level outputted from the selected averaging circuit at that time exceeds the threshold level or less than the threshold level, that is, the switch circuit 14 is controlled while the PLL of each averaging circuit is locked-in to select the average circuit on purpose.

Title: Microwave semiconductor device
Inventor: TAKAGI SUNAO
IPC: H03H11/24
Filed: 1982-03-10
Abstract: PURPOSE:To obtain an amplifier having a function controlling a gate with a small size and a simple constitution, by providing two gate electrodes for a microwave semiconductor device having sources, a drain and the gates and providing each gate between the drain and the sources. CONSTITUTION:The gates 21, 35 are provided between the drain 22 and the sources 20, 22. One of incident microwave powers reaches the 1st gate 24 and the other arrives at the 2nd gate 25 via a phase shifter 10. When the phase differentce is zero, the semiconductor device acts like a conventional field effect transistor FET, the power is amplified and outputted via the drain 28. When the phase difference is 180 deg., the microwave power is consumed in the device entirely and no output is obtained. Then, the device using two FETs conventionally is saved for one FET by changing the phase amount of the phase shifter 10, allowing to constitute an amplifier (or an attenuator) having the function controlling the gain, or a switch.

Title: Semiconductor element
Inventor: FUJIWARA NORIO
IPC: H01L21/321
Filed: 1990-02-19
Abstract: PURPOSE:To prevent the breakdown of an interface between an electrode and a solder bump, by forming a coating film having a specified thermal expansion coefficient on a semiconductor substrate and the electrode except a solder bump contact part. CONSTITUTION:After a solder bump 4 is formed, material having almost the same thermal expansion coefficient as the solder bump 4, e.g. polyimide resin, is spread on the semiconductor substrate 1 and the part on an barrier electrode 3, formed on the substrate, except a solder bump 4 contact part, thereby forming a coating film 7. When the substrate is mounted on a mounting board 6 and then subjected to reliability test like heat cycle test, the shearing force applied on the solder bump 4 is relieved by arranging the coating film 7. Hence the breakdown of interfaces between a leading-out electrode 2, the barrier electrode 3, and the solder bump 4 can be prevented. The thermal expansion coefficient of the coating film 7 is preferable to be in the range of 1.5X10<-5>-3.0X10<-5>/ deg.C and the thickness is preferable to be 0.5mum or thicker.

Title: Floating type magnetic head
Inventor: SUGIYAMA TAKASHI
IPC: G11B21/21
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To secure the high reliability in which a mirror adhesion does no occur by allowing an ABS surface to be brought into contact with a magnetic head surface at a prescribed angle when a magnetic disk is stopped to reduce the contact area between a slider and the magnetic head at the time of the stop. SOLUTION: Since the ABS surface of a slider 3 is stopped in a state in which it is inclined with respect to the disk surface by a projection part or a difference in level, the contact area between the slider and the disk surface is reduced and the mirror adhesion is prevented from being generated. Since the neighborhood of the flow-out end of the ABS surface including an electromagnetic transducer device is made to be projecting part, at the time of forming the ABS surface by cutting the part other than an area equivalent to the projecting part, the technique of a milling work can be used. Then, it is preferable that an angle θ formed by the ABS surface and the disk surface is within the range of 0<θ<0.1 deg. and in this slider, an SAL bias type MR head, a spin valve head or a GMR head can be used and, then, this magnetic head obtains a constant floating characteristic.
