Title: Ultrasonic wire bonding tool
Inventor: MATSUMOTO NORIAKI
IPC: H01L21/60
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To obtain the bonding directions of 360 degrees of a wire when the wire is subjected to ultrasonic welding and to contemplate to enhance the bonding work of the wire by a method wherein a pressing surface, which gives ultrasonic vibrations to the wire of an ultrasonic wire bonding tool, is formed on the periphery of the open part of a guide hole. SOLUTION: A wire W, which is fed through a nozzle 2, is made to penetrate a guide hole 11 and is clamped by a wire clamp 21 in a state that one part of the wire W is discharged from an open part 12a. By making a pressing surface 12 descend on an electrode pad on a first connection point, the wire W is subjected to ultrasonic welding in a state that the wire W is held between the surface 12 and the electrode pad. After that, the state that the wire W is clamped by the clamp 21 is released and the bonding wire W is moved to an electrode pad on a second connection point and is subjected to ultrasonic welding. At this point, even though the directions from the first connection point to the second connection point is not determined, a good bonding of the wire W can be performed because the surface 12 is formed into a ring shape.  After that, a bonding tool 1 is pulled up from the second connection point.

Title: Differential amplifying circuit
Inventor: KURAFUJI SETSUO
IPC: H03F3/45
Filed: 1982-03-30
Abstract: PURPOSE:To stabilize the output level, by connecting one input of a differential amplifying circuit to a reference signal and subjecting the reference signal to the temperature compensation. CONSTITUTION:A sense amplifying circuit of a MOS static memory consists of differential amplifying circuits DA1 and DA2. The circuit DA1 detects the potential difference between data bit lines DB and -DB and amplifies it. The circuit DA2 detects the difference between the potential level of an output signal SD of the circuit DA1 and the level of the reference signal and amplifies it. Output signals D and -D of the circuit DA2 are transmitted to a buffer OB of the next stage. When the temperature rises, the high level of the output D tries to be low because the conductance of a transistor TR is reduced. At this time, the leve of the reference signal rises because the conductance of a TR Q27 is reduced. Consequently, the level of the output D rises to perform the temperature compensation.

Abstract: PROBLEM TO BE SOLVED: To remove a sulfur odor efficiently by a small amount of a drug and to prevent the diffusion offensive odors and the corrosion of apparatuses by controlling the addition of a peroxide and/or nitrate ions based on the oxidation-reduction potential of a medium. SOLUTION: When sewage retained in a pit 102 in a pump site 101 reaches a definite level, the sewage is pumped up by a pump 111 to be supplied to a sewage treatment plant through a sewage pipe 112. The oxidation-reduction potential of the sewage is measured by oxidation-reduction sensor electrodes 103 and an oxidation-reduction meter 104. A measurement signal output from the meter 104 is input into a controller 105. Simultaneously, a flow rate signal is also input from a flow meter 110. The controller 105 calculates the amount of a drug to be added into the sewage by the signals and controls the actuation of a pump 106 for nitric acid and a pump 107 for adding hydrogen peroxide. In this way, a sulfur odor can be decomposed/removed by a small amount of the drug, and the corrosion of apparatuses can be prevented.
