Title: Flip-chip mounting apparatus, chip vacuum-sucking tool attached to the apparatus and method of mounting bare chip
Inventor: SENKAWA YASUHIDE
IPC: H01L21/60
Filed: 1997-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent adhesives from flowing in chip suction holes, by forming grooves around the holes at areas from the end face of a bare chip to the holes. SOLUTION: A chip suction chuck 31 has grooves 3 around chip vacuum holes 2 at its chip suction surface 1 within the outline projection contour range of a bare chip 21. The grooves 3 block adhesives from flowing to the holes 2 and have vent holes to change the air pressure in the grooves 3 through the vent holes, using a vent hole air pressure controller. The adhesives 35 extruding at the side of the chip 21 reach the suction surface 1 of the suction tool 31 or bonding head 12. Lowering the pressure in the holes 2 will cause the adhesives to flow between the surface of the chip 21 and suction holes 2, but the grooves 3 block the adhesives 35 from flowing, thus never sucking the adhesives in the holes 2.

IPC: H03B5/12
Filed: 1994-01-28
Abstract: PURPOSE:To eliminate the need for a 1/4 wavelength line and a ferrite and to attain miniaturization through circuit integration by forming the oscillator circuit with transistors (Trs) only or mainly employing Tgs. CONSTITUTION:An output noise of an amplifier fed to a terminal 2 of an irreversible 4-terminal circuit 10 is output terminals 3, 4, and an output signal from the terminal 3 is given to an amplifier 11, in which the signal is amplified and given to the terminal 2. Thus, an external feedback circuit is formed between an input terminal and an output terminal of the amplifier 11, and the entire circuit excites a free-oscillation signal at a frequency whose phase rotation is 360 deg. at a loop gain of one or over. In this case, an input signal to a terminal 1 is injected to the oscillator loop via the terminal 3, but the signal is not delivered to the terminal 1 in the electric behavior in the loop because of the irreversible characteristic of an input delivery section of the circuit 10 and the isolation between the input terminals 1, 2. Furthermore, the effect of a load is not delivered onto the oscillation loop connecting to the terminal 4 because of the isolation between the output terminals 3 and 4. The irreversible characteristic is realized over an ultrawide band from DC to its cut-off frequency by means of Trs and the circuit integration is facilitated.

Filed: 1992-02-12
Abstract: PURPOSE:To improve the operability by automatically writing information of skip channel selection to all idle position memories when a preset position is idle at the end of operation of an automatic channel selection preset function. CONSTITUTION:Information of skip channel selection is written to position memories succeeding to a preset position at the end of automatic channel selection preset operation by the software of a channel selection control microcomputer.

Title: Facsimile equipment
Inventor: NONAKA HIROTOMO
IPC: H04M1/27
Filed: 1997-02-07
Abstract: PROBLEM TO BE SOLVED: To reduce troubles to be applied to called station operator due to automatic calling by reducing redialing frequency when a called station does not automatically respond to a call from a calling station and an operator of the called station responds to the call. SOLUTION: When automatic calling is executed from the calling station to an exchange 13, a ring signal is sent from the exchange 13 to the called station 14. When the operator of the called station 14 hooks up a telephone receiver, catches a line 4 and judges that the calling station is a facsimile equipment by a CNG tone signal, the operator hooks on the receiver and disconnects the line 4. The exchange 13 sends a line disconnection informing tone signal to the calling station to inform the calling station of the line disconnection of the called station 14. When the called station detects the line disconnection informing tone signal from the exchange 13 by a tone detector 8b in a MODEM 8 without detecting a busy tone signal from the called station 14, a CPU 6 rewrites remaining redialing frequency stored in a memory 7 to reduce it.  Consequently troubles applied to the operator of the called station 14 can be minimized.
