Title: Capillary for bump formation, bump forming equipment and bump forming method
Inventor: SHIFU HIDEJIRO
IPC: H01L21/60
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent a bump from sticking to a capillary inner wall when the capillary is lifted, by arranging at least one penetrating hole on a wall surface of a tapered part whose aperture diameter is increased toward a wire leading-out part. SOLUTION: Penetrating holes 4 are used as air holes suck that a metal bump 11 is prevented from sticking to a wall surface of a tapered part 3. Otherwise, four ventilating holes positively sending air from the outside are formed concentrically along the aperture diameter of the tapered part 3, at intervals of 90 deg., and preferably, in the direction perpendicular to the wall surface of the tapered part 3. Sticking to the wall surfaced of the tapered part 3 can be prevented by increasing the number of the penetrating holes 4, but excellent result can be obtained sufficiently, by almost four in the concentric state. Effect can be obtained by one penetrating hole 4.  When the penetrating holes 4 are formed in the direction perpendicular to the wall surface of the tapered part 3, air collides against the metal bump 11 perpendicularly, so that the sticking to the wall surface of the tapered part 3 can be prevented more effectively.

Title: Optical coupling type relay circuit
Inventor: MATSUMOTO TAKESHI
IPC: H03K17/78
Filed: 1987-11-13
Abstract: PURPOSE:To stabilize the switching operation of a relay circuit by providing the second control transistor 4 of a normally ON type in order to switch the impedance of an impedance element at the time of ON of the relay circuit and at the time OFF and allowing an operating point to an input signal to have a hysteresis characteristic. CONSTITUTION:When an optical current flows through transistors 3, 3 of a normally ON type and a resistance 5, a voltage drop is generated at both ends of the resistance 5, and becomes a voltage for biasing between the gate and the source of the transistor of a normally ON type. When the magnitude of an input signal reaches an operating point, the transistor 3 becomes a high resistance state by a voltage drop generated by the resistance 5. Therefore, a MOSFET 7 becomes ON, and a load current flows to a load 10. Simultaneously, the transistor 4 of a normally ON type becomes a high resistance state by said photoelectromotive force, therefore, a higher bias voltage is applied between the gate and the source of the transistor 3 of a normally ON type. Accordingly, even if the input signal is varied to some extent in the vicinity of an operating point, the MOSFET 7 does not become OFF.

Abstract: PURPOSE:To ease a tension caused by an environmental sound by adding a fluctuation noise composed of a power spectrum and time component inversely proportional to its frequency to the environmental sound present in a determined sound space, and further adding a significant sound or pure sound thereto. CONSTITUTION:When a fluctuation noise control mode of 1/f or 1/f2 is designated according to a first acoustic environment control mode designation data DCMD by means of an operation input part 8, a CPU 5 generates a wide band noise data D1 from a wide band noise generating part 2, takes said data into an acoustic environment control sound signal generating part 6, generates an acoustic environment control sound signal SOUT having frequency spectrum characteristics including the power spectrum component of 1/f or 1/f<2>, and generates a fluctuation noise from a sound system 7. Similarly, the wide band noise generating part 2 and a significant sound generating part A, or the wide band noise generating part 2 and a pure sound generating part 3 are operated simultaneously with all generating parts by each control mode designation. Hence, an acoustic environmental control sound signal cepable of easing physiological and psychological tensions can be generated from the sound system 7.

Title: Bias circuit
Inventor: OBANA BUNICHI
IPC: H03F3/45
Filed: 1989-11-06
Abstract: PURPOSE:To obtain speedy rise time by driving a capacitor for power supply noise removal by a constant current source until a specified voltage is obtained after turning on a power source. CONSTITUTION:When a power supply voltage Vcc is rised, bias voltages V2 and V3 are respectively applied to the two base inputs of a differential circuit composed of transistors Q1 and Q2. In the case of V2>V3, the transistor Q2 is turned OFF and an emitter current IE flowing to a resistor R5 flows only to the transistor Q1. Then, a voltage drop is generated in a resistor R6 by a collector current and a transistor Q3 is turned ON and added as a current source Io. Afterwards, the output current of the current source Io is supplied to a capacitor C1. Thus, without increasing current consumption and lowering the noise removing rate of power supply noise, when the power source is turned on, the rise time of the bias voltage can be made speedy.

Title: Detecting sheet for absorption of water
Inventor: KOYANAGI MASARU
IPC: G01N27/00
Filed: 1993-10-22
Abstract: PURPOSE:To quickly detect leak of a highly insulating pure water by forming a pair of soft conductive layers on a flexible insulating sheet, coating an insulating, water-absorbing layer over the outer surface of the layers, impregnating the water-absorbing layer with an electrolyte and drying it. CONSTITUTION:A pair of slim soft conductive layers 2 are formed by a printing/ etching method or the like on the surface of a flexible insulating sheet 1 of polyimide (0.1-0.4mm thick). An insulating water-absorbing layer 3 of fibers of a Japanese paper or the like is coated all over the conductive layers 2 with a thin starch. An electrolytic solution of drying and insulating properties, e.g. 0.1% solution of salt is uniformly infiltrated into the water-absorbing layer 3, which is then dried by a hot air, etc., to constitute the sheet for detecting the absorption of water. When the water-absorbing layer 3 absorbs pure water, an electrolyte is dissolved in the pure water and the water is turned to an electrolytic solution passing electricity. Therefore, even a highly insulated pure water can be detected by a comparsion circuit, etc., because a resistance or an impedance between the pair of conductive layers 2 is decreased.

Title: Laser beam processing device
Inventor: HIRUKAWA SHIGERU
IPC: B23K26/082
Filed: 1986-12-05
Abstract: PURPOSE:To permit partial and satisfactory removal of a resist film on a prescribed substrate or the like by condensing laser light of a CW laser, scanning said light on an object and processing the object while monitoring the processing condition of the object. CONSTITUTION:Reflected light is generated from a wafer W or resist and further, fluorescence is generated from the resist when said wafer or resist is irradiated by the laser light LB outputted from a light source 10 of the CW laser. Such reflected light and fluorescence are partly entered by the effect of a beam splitter 20 and a fluorescent lens 36 to a photodetector by which the light is photoelectrically converted and a detection signal is outputted to a system controller 34. The presence or absence of the resist is judged in said controller. The reflectivity to the laser light LB varies with the resist and the wafer W in a mode in which the reflected light is selected and, therefore, whether the resist is satisfactorily removed or not is judged by the change in the intensity of the incident light on the photodetector 38.

Filed: 1985-12-20
Abstract: PURPOSE:To suppress abnormal voltage generated with switching action, by delaying a switching time for the ON/OFF operation of a power MOSFET. CONSTITUTION:The output voltage of a synchronous generator 1 is converted to direct current by a transformer 6 and a rectifier 7. By an adder 8, deviation signal between the detected voltage of the synchronous generator 1 and reference voltage from a voltage setting device 9 is applied to an integrating device 10. By a comparator 11, the output signal of the integrating device 10 and a threshold are compared with each other, and the output of positive or negative control signal is generated. The control signal from the comparator 1 is fed to the gate of a power MOSFET4 via a time constant circuit consisting of a resistance R4 and a capacitor 13. As a result, a rise time and a fall time for the ON/OFF operation of the power MOSFET are delayed, and with the action of the power MOSFET, 1 surge voltage applied to each element can be suppressed.
