Title: Manufacture of semiconductor device
Inventor: SUGAYA TADASHI
IPC: H01L21/3205
Filed: 1981-08-08
Abstract: PURPOSE:To obtain a virtually flat-surfaced electrode with no appreciable step portions in the electrode formation on a semiconductor substrate by burying electrode material in a hole having step differential dug in stacked layers of an oxide film and an oxide film with no addition of impurities which are formed to cover the entire substrate surface. CONSTITUTION:An oxide film 12 and an oxide film 13 with no addition of impurities are formed in stack to cover a one conductivity type Si substrate 11, and a hole 14 for electrode formation is dug by etching with a photo resist. After replacing this resist with a new photo resist 15, a hole 141 larger than the hole 14 is made over the hole 14, and a film 13 exposed on the circumferential edge of the hole 141 is removed by etching to form a step portion 16 on the  films 13, 12. An Al 17 is formed to cover the entire surface without removing  the film 15, and the film 15 with the Al layer 17 thereupon is removed while  the Al layer 17 within the hole 14 is left intact. A surface-protective oxide film  18 with no addition of impurities is applied to cover the entire surface, a window hole 19 is then dug in conformity with the layer 17 to obtain an electrode  formed by the layer 17 for wire bonding.

Title: Error correction device
Inventor: MATSUMOTO MICHIHIRO
IPC: H03M13/00
Filed: 1988-05-20
Abstract: PURPOSE:To make the syndrome preparation processing timing and the error correcting arithmetic processing timing asynchronous from each other so as to improve the processing efficiency of the title device by delivering and receiving syndrome through a storing means. CONSTITUTION:A syndrome preparing means 12 can successively calculate syndromes of different sequences without waiting for the processing operation of an error correction arithmetic means 13. The syndrome preparing means 12 and the error correction arithmetic means 13 can operate in parallel with each other to such an extent that the access of the data in a storing means 11 does not conflict. Therefore, the waiting time of each means is reduced, and as a result, the processing time of this whole error correcting device can be made more efficient. Moreover, the syndrome preparing means 12 is different from the conventional syndrome preparing means in such a point that the means 12 can write in the storing means 11 and, therefore, the increase in hardware is very little.

Title: Automatic power factor regulator for self-exciting ac generator
Inventor: TANAKA TOSHIO
IPC: H02P9/30
Filed: 1977-10-19
Abstract: PURPOSE: To adjust the power factor of an AC generator which is operated in parallel with a system by applying the inter-phase voltage of a generator to the Toulon circuit consisting of a capacitor and a resistor and combining this voltage vector and the phase current vector.  
     CONSTITUTION: The 2-to 3-phase voltage of an AC generator is applied to the Toulon circuit consisting of a generator 33, power factor setting resistor 34, and compensating  resistor 35 and the two voltage vectors of the same phase and voltage are generated in accordance with the output. Also, phase current is removed from an auxiliary current transformer 7 through a current transformer 6 and power factor deviation signals are obtained by combining these two vectors. By connecting the generator with an automatic voltage regulator, field current decreases at lag power factor and increases at lead power factor. As a result, an arbitrary operation power factor can be set by adjusting the resistor 34 and an economical and compact automatic power factor regulator be obtained without a phase shift transformer

Title: Clock generator and clock generating method
Inventor: SUMIDA MASAYA
IPC: H03L3/00
Filed: 1995-05-24
Abstract: PURPOSE:To stop a PLL circuit completely without generating a DC path by controlling a voltage controlled oscillator so as not to be oscillated in response to a reset signal and making a phase difference of two clock signals zero. CONSTITUTION:The operation of a PLL circuit 1000 when a reset signal 104 is at a high level is similar to that of a conventional method. When the signal 104 is at a low level, signals 105, 106 outputted from an input interrupt control circuit 14 go to a low level. As a result, since a phase difference between the signals 106, 106 is zero, an output signal 101 from a phase comparator 11 is zero. A loop filter 12 trys keeps a voltage of the signal 102. However, since the voltage of the signal 102 is pulled down to 0V by a voltage fixing control circuit 15, the voltage of the signal 102 is st to 0V. As a result, since a voltage controlled oscillator 13 is not oscillated, the output of the oscillator 13 goes to a low level.
