CONSTITUTION:A copper film 3 is etched and removed by making use of a photoresist film 4A as a mask. Then, a second SiO2 film 5A is grown selectively by liquid-phase epitaxy. Then, the photoresist film 4A is stripped off; after that, a copper-plated film 6A is grown selectively by using electroless plating method. Then, a photoresist film 4B is formed on the copper-plated film 6A in a part where a through-hole is to be formed; after that, a third SiO2 film 5B is grown selectively by using liquid-phase epitaxy. Then, the photoresist film 4B is removed; a copper-plated film 6B is grown selectively by electroless plating method. Thereby, it is possible to obtain a flat interconnection layer which uses the copper-plated film 6A as a first-layer interconnection and which uses the copper-plated layer 6B as an electrode which has been buried in the through-hole.

Title: Light pulse testing apparatus
Inventor: KITAGAWA KAZUMA
IPC: G01M11/00
Filed: 1982-03-31
Abstract: PURPOSE:To automatically remove the zero level drift signal component, by making the lowest level value of a reflection signal from a DC amplifier coincident with a lower limit level that can be converted by an A-D converter at all times by means of a feedback circuit. CONSTITUTION:A microprocessor 11 effects such a data processing as successively reading out data from a memory 12 storing data on the waveform of a reflection signal (a) digitized in an A-D converter 3 and subtracting from each of the data the zero level drift signal component data stored in the memory 12. The memory 12 stores the data on the waveform of the reflection signal (a) digitized in the A-D converter 3 and the zero level drift signal component data processed by the microprocessor 11. An A-D converter 13 calculates an average value of the zero levels of the reflection signal (a) digitized in the A-D converter 3 and converts the reflection signal (a) to an analog value again using the average value as a correction value. An amplifier 14 and the A-D converter 13 in combination constitute a feedback circuit, which makes the lowest level value of the reflection signal (a) delivered from a DC amplifier 2 coincident with the lower limit level that can be converted by the A-D converter 3.

Title: Current mirror circuit
Inventor: YAMAGUCHI HIROYASU
IPC: H03F3/34
Filed: 1982-03-31
Abstract: PURPOSE:To realize the stable operation independent of a power source voltage even under a low voltage, by constituting an amplifying part with the Darlington connection and by-passing a partial current. CONSTITUTION:Base currents IB of transistors TRs Q11and Q12 are flowed to the emitter of a TRQ15, and the output current from the collector of the TRQ15 is added to the collector current of TRQ14 to a compensate the loss due to the TRQ14. When collector currents IC of the TRsQ11 and Q12 are equal to each other, their base current IB are equal to each other, and therefore, the emitter current of the TRQ15 becomes 2IB. A compensating current is outputted from the TRQ15. The error between an input current Ii and an output current Io is reduced to Ic/beta.(beta+1). Consequently, the error is reduced even if a TR having a low current amplification factor beta is used.

Abstract: PURPOSE:To stably maintain the DO concn. of an aeration tank without generating overaeration and underaeration even in the vent of an abrupt fluctuation in load by computing the correction rate of a blast rate at the time of the fluctuation in load, thereby correcting the deviation quantity of the blast rate in the case of controlling of the blast rate to the aeration tank. CONSTITUTION:This blast rate controller 11 controls the blast rate from a fan 7 to the aeration tank 4 so as to maintain the DO concn. of the aeration tank 4 at a specified value. The deviation quantity of the blast rate is calculated by a feedback controller 13 in accordance with the DO concn. of the aeration tank 4 and the target value thereof. On the other hand, the flow rate of the sewage in the aeration tank 4, the concn. of suspended solids, the temp. of the water, the blast rate and the DO concn. are respectively stored by a process data storage device 12. The correction rate of the blast rate at the time of the fluctuation in load is computed by a first arithmetic means 14 in accordance with the stored data. Further, the correction rate between the predicted blast rate and the blast rate just before the fluctuation in load is computed by a second arithmetic means 15. The deviation quantity of the blast rate and the correction rate are added by an adder 16 and the blast rate is thus controlled.

Abstract: PROBLEM TO BE SOLVED: To prevent the development of hitting mark and crack on a casting by recognizing the casting supplied into a rotary drum with a casting recognizing instrument and adjusting the number of revolutions of the rotary drum based on the recognized result, molding time cycle and a casting wt. SOLUTION: Molding sand M and the casting C are charged into the rotary drum 6 in a rotary drum type sand treating equipment 2 through a vibration conveyor 1. The shape of the casting C is recognized with a sensor 16 in the casting recognizing instrument. The optimum number of revolutions of the rotary drum 6 is calculated based on the inputted molding time cycle, casting molten metal wt. and the shape of the casting C and the molding sand M quantity recognized with the sensor 16. When the molding sand M is much quantity in the rotary drum 6, since the casting C receives buffering action and is difficult to receive the damage, the number of revolutions is increased.  When the molding sand M is little quantity or when the shape of the casting C is complicate, the number of revolutions is decreased and the molding sand M is stayed at the inlet side of the rotary drum 16 to prevent the damage to the casting C.

Title: System for managing label table
Inventor: IWAMOTO SHINICHI
IPC: G06F9/45
Filed: 1987-03-11
Abstract: PURPOSE:To ensure the effective reference to a label table by varying the entry number of a hash table based on the label definition, thereby suppressing the increase of the synonyms having one and the same hash value. CONSTITUTION:The initial value of a label definition counter 1 is set at 0 at a conversion program execution processing part 11 consisting of a computer. Then the counter 1 is counted up at every time a word/phrase analyzing part 12 detects the label definition out of a source program 16. The value decided by the counted value of the counter 1 is written into a hash table entry number area 2 at a time point when the detection is through with the label definition. Thus an entry area is secured in a label table 15 and a syntax structure meaning analyzing part 13 refers to the entry area via the label supplied from a 1st intermediate language. Then a conversion part 14 performs previously the prescribed arithmetic processing to the label via a decided program stored in a memory 3. Thus the increase of the synonyms having the same has value is suppressed without changing the label reference multi-process procedure and registration.
