Title: Method of bonding wire containing gold with solder
Inventor: EICHI WAADO KONRU
IPC: H01L21/607
Filed: 1989-09-20
Abstract: PURPOSE: To improve the adhesion between a gold wire and the lead-tin solder by inserting a pole of a terminal of a wire, which includes gold, into a solder layer in the condition that it dose not reach a board. CONSTITUTION: A terminal of a wire 12 is formed into a gold or gold alloy pole 14, and it includes gold at least at 50%, and it is inserted into a solder pad 16 by crimping such as thermal sound wave, ultrasonic wave, thermal crimp. This pad 16 receives a terminal of the wire, and at this stage, the wire does not pass through the pad so that it does not contact with the board, and the wire is separated from the board 20, and pushed at a distance in the condition that it is surrounded by the tin solder. A remarkably thin metal-to-metal compound 30 is obtained by the crimping, and this metal-to-metal compound 30 supports the adhesion of the wire and the solder. At this stage, solder is maintained at a temperature lower than the lowest eutectic point of the solder.

Title: Manual picture reader
Inventor: FUTAKI HISATSUGU
IPC: H04N1/107
Filed: 1987-09-28
Abstract: PURPOSE:To use an electric circuit so as to adjust read width simply and inexpensively by comparing an analog voltage in response to the count of picture element number with a voltage proportional to an optional read width. CONSTITUTION:While an output of an image sensor 10 is being binarized, the number of picture elements is counted by a picture element number counter 14 for one main scanning period. The count number is converted into an analog voltage Vp 15 and compared with a reference voltage Vw in response to the read width set optionally by a comparator 16. When an analog voltage Vp in response to the number of picture elements is over the reference voltage Vw in response to the read width, the gate circuit 13 is opened and AND or OR is calculated and the number of picture elements by the set read width is written in, e.g., the memory. Thus, in reading only the desired part of picture information, the adjustment is facilitated.

Title: Cream solder
Inventor: OSAKI KATSUHISA
IPC: B23K35/22
Filed: 1994-09-12
Abstract: PURPOSE: To attain the higher density of electronic apparatus by dispersing substantially spherical superfine powder having a specific grain size into cream solder. CONSTITUTION: The solder powder is dispersed into the cream solder to be used for reflow soldering of electric circuit boards. The solder powder is formed as the superfine powder having an average grain size of <=1μm and the substantially spherical shape in particle shape. The surface of such solder powder is coated with an org. material. The org. material coating consists of a component constituting the vehicle of the cream solder. For example, fine pattern printing of a pitch of <=0.3mm with good accuracy is sometimes not possible in the case of the solder powder having the average grain size over 1μm. Good flow is obtd. and a discharge property stabilizes when the cream solder is discharged by a dispenser and, therefore, the accurate pattern printing is executable. As a result, the fine pattern printing of the pitch of <=0.3mm is executed.

Title: Insolubilization of aluminum
Inventor: SATO SHIN
IPC: C02F1/52
Filed: 1991-09-24
Abstract: PURPOSE:To perform efficient treatment by forming sludge improved in sedimentation properties, concn. properties and dehydration properties in a method subjecting aluminum containing water to flocculation treatment to separate and remove formed sludge. CONSTITUTION:A part of sludge separated in a sedimentation tank 4 is returned to a reaction tank 1. The pH of the reaction tank is set to 5.8-7.2, the concn. of the solid in said tank is set to 100g/l or more and the stagnation time of the tank 1 is set to 10min or more. By this method, sludge improved in sedimentation properties, concn. properties and dehydration properties is obtained in high concn. Since sludge with water content lower than that of a dehydrated cake can be obtained only by concn. treatment, a dehydrator is dispensed with or contracted. The drying cost in a case recovering and reutilizing aluminum in sludge is reduced to a large extent.

IPC: G06F5/06
Filed: 1989-09-21
Abstract: PURPOSE:To set a delay time with high accuracy by writing an address data based on a clock input to an address indicated by a write address generating means and sequentially reading the data based on the clock input. CONSTITUTION:An input signal is inputted to a latch circuit 2 and latched at the rising of a counter clock. The signal passes through a buffer 3 gated by the same counter clock and written in a memory address indicated by a write counter 9 from an input output terminal I/O of the memory 4. Moreover, the data of the memory address indicated by a read counter 10 passes through the terminal I/O from the memory 4 and through an output latch circuit 5 and is read by an output terminal. The data write and read to the memory 4 is implemented alternately by a read write timing signal (R/W signal) from a read write timing generating circuit 13. Thus, the time (delay time) requiring of read from the write of the input data is a time NXT being the multiplication between an address difference N and an address UP period T.

IPC: C02F3/12
Filed: 1992-09-14
Abstract: PURPOSE:To provide an operation control method of an aerobic-anaerobic active sludge treatment apparatus by which nitrification and denitrification in waste water is promoted to improve a total denitrification ratio. CONSTITUTION:The temperature of water to be treated is measured by a thermometer 15, total nitrogen concentrations of specimens collected from respective reaction tanks are determined by a total nitrogen analyzer 16, and nitrogen components are measured by a nitrogen component analyzer 17. An average sludge retention time(SRT) required is calculated from the relationships between the water temperature and the total denitrification ratio obtained experimentally in advance. The operation of an aerobic-anaerobic active sludge treatment apparatus is conducted by controlling SRT so that the increase in the total nitrogen concentration is prevented. The sludge extracted from the bottom of the final sedimentation pool 4 is led to a sludge separation vessel 11, and the amount of the sludge to be extracted from the pool 4 is controlled by changing the opening of an excessive sludge discharge valve 13 corresponding to the progress of the nitrification reaction.

Title: Digital arithmetic circuit
Inventor: SAGAWA KENTA
IPC: H03G11/00
Filed: 1986-10-15
Abstract: PURPOSE:To realize a characteristic executing a desired limiting action with an adder and a few control circuits by permitting the adder and a constant output circuit to add an input value to a negative prescribed value and an output switch circuit to specify an output value. CONSTITUTION:The adder 4 and the constant output circuit 3 add the input value to the negative prescribed value. Outside a prescribed range where the input value is limited, a carrier from the most significant bit of the adder 4 is of logic '0'. If the input value is within the prescribed limit range, the carrier from the most significant bit of the adder 4 is of logic '1'. Exploiting these facts, the output switch circuit 6 decides whether the carrier output of the most significant bit of the adder 4 is of logic '0'. If so, the output value takes any constant of N-bits (N: integer greater than zero), which is expressed by natural binary numbers. Thus, the circuit executing a limiting action can be realized with the adder 4 and a few control circuits.
