Title: Bonding head and bonding method of flip chip
Inventor: ONIZUKA YASUTO
IPC: H01L21/60
Filed: 1991-08-13
Abstract: PURPOSE:To bond a flip chip to a substrate by grounding a bump of a flip chip on an electrode of a substrate and a hot pressure bonding piece on a nozzle, by bonding the bump to the electrode and by lifting the nozzle and the hot pressure bonding piece. CONSTITUTION:A motor 11 rotates in the normal direction with a bump B of a flip chip P positioned immediately above an electrode 52 of a substrate 51. A nozzle 3 lowers and the bump B grounds on the electrode 52. A rod 22 of a cylinder 21 projects and a thermo-compression bonding piece 4 grounds on an upper surface of the nozzle 3. The bump B and the thermo-compression bonding piece 4 are pressed hard to the electrode 52 and the nozzle 3, respectively and further heated to fuse the bump B and bond it to the electrode 52. The rod 22 of the cylinder 21 is withdrawn a little to raise the thermo-compression bonding piece. A gap G is ensured, heat conduction is restrained and load is released. A refrigerant is blown off from a blow-off hole 25 to cool the nozzle 3. The bump B is cooled and set, fixed to the electrode 52 firmly, and excellent bonding is realized.

Title: Slip control device for direct connection clutch for vehicle
Inventor: MATSUBARA TORU
IPC: F16H59/38
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To suppress a sudden change in engine speed cused by the termination of slip control by providing a speed reducing slip-control terminating means for substantially terminating control of the amount of slip during the speed reduced travel at a higher rotating speed of an input shaft with increasing the gear ratio of change gears in response to the change gear actually selected. SOLUTION: In the third and fourth gears, an electronic control device 78 for gear change, judges either area out of release, slip, engagement based on the throttle valve opening TA, the car speed V, from various kinds of relationships preliminarily stored in a ROM, and executes slip control of slip clutches. That is, the electronic control device calculates an actual amount of slip, calculates driving duty ratio of a linear solenoid valve SLU from the deviation of the actual amount of slip from a target amount of slip, and adjusts the control pressure outputted from the same valve SLU. Then, at this time, the electronic control device judges the change gear actually selected to control the amount of slip so that the control of slip during the speed reducing travel at higher input shaft rotating speed with increasing the gear ratio is substantially terminated.

Title: Manufacture of semiconductor device
Inventor: KAWAMURA EIICHI
IPC: G03F7/36
Filed: 1989-08-04
Abstract: PURPOSE:To form with high accuracy a multilayer resin film pattern which has few defects by restricting the remaining film thickness of a lower organic resin film and determining the film thickness of an upper organic resin film while joining its upper film with the lower film when the surface of an intermediate metallic resin film pattern is exposed to the outside in the process of dry- etching of the lower organic resin film after making patterns of the upper organic resin film and the intermediate metallic resin film act as masks. CONSTITUTION:A lower resist film 3 is etched by employing patterns 5' and 4' of an upper resist film and an intermediate SOG film as masks and applying an RIE process in which a CF4 gas is used instead of an O2 gas. In such an etching process, even an upper resist film pattern 5' is etched simultaneously and when the surface of the intermediate SOG film pattern 4' is exposed, the residual film thickness of the lower resist film 3 comes to 1.0mum. Subsequently, when the residual film thickness (h) of the resist film 3 is etched by making the above SOG film pattern 4' to act as a mask, a lower resist film pattern 3' is formed. Since the remaining film thickness of the above film 3 does not exceed 1.0mum, occurrence of defects in the pattern is suppressed to a minimum.

Filed: 1983-10-28
Abstract: PURPOSE:To obtain the device of measurement and pressure transfer capable of easily controlling, in case of measuring the contained amount of gas, etc. mixed in raw material in the molding process of the resin such as polyurethane, by measuring the above amount with the pressure transfer device of a cylinder piston system. CONSTITUTION:When the valve 14 of a cylinder piston 21 is closed, said piston 21 is retracted, and the specified amount of resin component G is sucked into a cylinder pump 10. When an arm 23 is caused to be in contact with a bimit switch 24 and causes it to operate, a valve 13 is closed, and thus the resin component A is temporarily closed in an encapsulating part 15. The pressure of the resin component A in the encapsulating part 15 under this condition, is measured by a pressure gauge 17. Next, the piston cylinder 21 is advanced and stopped, and after this movement, the pressure of the resin component A is measured. On the other hand, the moved distance of the cylinder piston is measured. From these values, the contained bubble amount of the resin is calculated based on the law of Boyle.

IPC: G11C11/413
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To provide an internal power source circuit which has high capability of controlling the internal power source voltage when the sense amplifier operates. SOLUTION: During the period when the row address strobe signal/RAS is brought into the L level to operate the sense amplifier and the internal source voltage int Vcc decreases greatly, external signals ϕ1 and A become the H level to operate only the circuit 115 which includes a differential amplifier circuit a little low in sensitivity so that the power source circuit does not react too sensitively for the variation of the internal power source voltage int Vcc.  After the sense amplifier operates no longer and the internal power source voltage int Vcc is roughly stabilized, the external signal A becomes the L level; the external signal B becomes H level and the circuit 115 which includes the differential amplifier circuit of low sensitivity is switched to a circuit 117 which includes a highly sensitive differential amplifier circuit so that the power source circuit reacts sensitively to the variation of the int Vcc.

Title: Holding canceling system
Inventor: NISHINO TSUTOMU
IPC: H04M3/42
Filed: 1988-08-18
Abstract: PURPOSE:To prevent a person, whose call is suspended, from waiting for a telephone call for long time by canceling the suspension from a telephone set, which holds the call, and a telephone set, whose call is hold, when the call is suspended. CONSTITUTION:A discriminating means can discriminates the input of holding cancel indication from the telephone set, whose call is hold. Then, a channel forming means forms a channel to the telephone set and the telephone set, which executes such a holding request, when the input of the holding cancel indication from the telephone set, whose call is hold, is discriminated. Accordingly, the call to be once hold can be canceled not only from the telephone set, which holds the call, or a telephone set in a transferring destination but also from the telephone set, whose call is held. Then, even when the person, whose call is held, is caused to wait for the call for a long time, the call to be just held can be canceled by the self-telephone set. Thus, calling can be executed again with the preceding telephone set.

Title: Fastener
Inventor: JIYOOJI JII DEYUUEI
IPC: F16B13/04
Filed: 1991-07-22
Abstract: PURPOSE: To obtain a self-drilling fastener by integrating the drilling tip with a fastener body and extending it axially beyond a toggle clamp in its insertion position. CONSTITUTION: A fastener 10 comprises a fastener body 40 and a toggle clamp 42. As an integral part of the fastener body 40 a drilling tip 50 is integrated with a long and a narrow arm 48. When a hole 28 is drilled with a drilling tip 50, a central cutter 62 penetrates through an outer paper layer 24 and a core 22 perfectly, minimizing the risk of a spiral cutting edge of an outer cutter 64 damaging the outer paper layer 24. The toggle clamp 42 allows its pivoting and axial movement with respect to the fastener body 40 between an insertion position and a toggle position, which coincides with the arm 48 in the insertion position and making a right angle with the arm 48 in the toggle position. Since the fastener body 40 is susceptible to deformation or break up, axial movement can be prevented before its deformation.
