Title: Waveform shaping circuit
Inventor: SUZUKI TAKAYUKI
IPC: H03K12/00
Filed: 1986-06-18
Abstract: PURPOSE:To attain the waveform shaping without using a diode by using a comparator comparing an AC signal with a reference potential and an analog switch outputting a prescribed component of the AC signal based on the switch control by the output. CONSTITUTION:The output of the comparator COM is brought into a high level at the positive cycle of the AC signal S1 and into a low level at the negative cycle. The analog switch SW outputs an AC signal S2 of positive polarity corresponding to the AC signal S1 while the output signal of the comparator COM is at a high level. The analog switch SW is turned off while the output of the comparator COM is at a low level and its output is kept to a ground potential until the analog switch SW is turned on next. Thus, only the positive signal component of the AC signal S1, being subject to half-wave rectification, is outputted from the analog switch SW.

Title: Method for patterning vapor-phase synthetic diamond film
Inventor: KURIHARA KAZUAKI
IPC: H01L21/205
Filed: 1987-06-04
Abstract: PURPOSE:To easily pattern a diamond film without damaging the film by forming a patterning mask on a substrate with a metal dissolving C such as Ni, Fe, and Co, and forming a vapor-phase synthetic diamond film on the substrate. CONSTITUTION:A gaseous mixture of CH4 and H2 is excited by microwave plasma to form the synthetic diamond film 2 by vapor-phase on the SiC substrate 1. An Ni film is deposited thereon by sputtering and photolithography to form the patterning mask 3. A vapor-phase synthetic diamond film 4 is formed in the same way as before by using the patterning mask 3. The diamond film 4 is hardly grown on the patterning mask 3, and selectively grown on the region not covered with the mask 3. The patterning mask 3 is subsequently dissolved and removed by using an etchant such as nitric acid. The diamond film is thus patterned with a less number of stages and without being damaged.

IPC: H04Q1/20
Filed: 1987-06-04
Abstract: PURPOSE:To shorten the stop time of a system by executing basic call processing programs, sequentially transferring additional service processing programs required to a storage part and executing them at the time of resumption processing. CONSTITUTION:When the resumption processing is required, a central control unit 5 executes resumption processing programs 10 stored in a non-volatile storage part 1. When a system comes to an operational state, the central control unit 5 collates a local data storage part 3 and identifies the kinds of additional service required in the system. As to additional service required, the central control unit 5 uses the idle time of a call processing and the like, executes the additional service processing programs and transfer programs, reads the additional processing programs concerned from a backup storage part 4 and writes them into an additional service program area 20 in a volatile storage part 2. Furthermore, the unit 5 sets the start address of the additional service processing, which has previously been transferred in an index table area 21 corresponding to the kinds of additional service concerned. Thus, a time when the system cannot be shifted to the operational state is shortened.

Title: Chip coil
Inventor: KANEKO TOSHIMI
IPC: H01F27/00
Filed: 1989-06-02
Abstract: PURPOSE:To extremely reduce irregularity in inductance by polishing the upper face of a body core and the upper face of a sleeve core, and regulating inductance. CONSTITUTION:Cores 1, 3 are temporarily secured by filling temporarily securing adhesive 5 between the core 3 and a winding 2. An upper collar 1a and the upper face of the sleeve core 3 are integrally polished in thickness T as previous step of primarily securing it with adhesive 6. The relationship between the polishing amount and inductance L is obtained by measuring the inductance L of a manufactured chip coil based on a graph obtained in advance in response to the irregularity. When the upper face of the coil is polished, a chip coil having a predetermined L value is obtained. Since it has the core 3, its quality factor Q is high such as 100, and the L value is also high such as 0.5muH/mm<2>. Further, the deviation of the L value is finished to 2-5% by polishing the upper faces of the cores 1, 3 and the less deviation can be finished by raising polishing accuracy.
