Title: Die bonder device
Inventor: HIROTA KAZUO
IPC: H01L21/52
Filed: 1982-01-29
Abstract: PURPOSE:To prevent chip breaks or cracks when a die-bonding is performed, by giving the oscillation in a fixed amplitude to a die collet so as to rotate a cum forward and backward at a rotation angle according to the amplitude. CONSTITUTION:In a control circuit 10 for the rotation direction of a motor 6, when controlled so as to vary the rotation direction of the motor 6 at every 20 pulse count for example with zero signal as the center, the cum 7 rotates forward and backward at the rotation angle of + or -20 deg.. Thereby, a die collet support rod 5 is allowed to generate the oscillation in the amplitude corresponded to the shape and rotation angle of the cum 7, and accordingly a semiconductor chip is rubbed against a reinforcement substrate by this amplitude. Controlled by the circuit 10 so as to reduce the rotation angle of the cum 7 at the beginning and end of die bond and increase the angle in the halfway, then an oscillation is thus given to the support rod 5, and thus the rubbing between the semiconductor chip and the reinforcement substrate is adjusted. Thereby, the stress applied on the chip at die-bonding can be reduced, and the occurrence of breaks and cracks can be prevented.

Title: Mass spectrograph
Inventor: MARUYAMA HIROSUKE
IPC: H01J49/32
Filed: 1983-01-28
Abstract: PURPOSE:To measure an ion spectrum accurately by providing a fine magnetic field varying at a remarkably higher cycle than the electric field-magnetic field sweeping cycle in front of a collector-slit. CONSTITUTION:A fine magnetic field 9 varying at a fixed cycle is provided in front of a collector-slit 7 of a double forcusing mass spectrograph. The sweeping cycle of the magnetic field is reduced noticeably as compared with the cycle of a linked scanning in the electric field-magnetic field. With such an arrangement, the distortion and the lowering of the intensity in the profile of a metastable ion spectrum due to deviation of the sweeping curve (b) of the electric field-magnetic field from the ideal curve (a) is corrected by the sweeping of the fine magnetic field 9 to ensure that the sweeping curve crosses the ideal curve (a) and hence, the peak of the metastable ion passes through the collector-slit 7 to enable an accurate measurement.

Filed: 1986-01-23
Abstract: PURPOSE:To enable a stable tension to be constantly applied to an ink film, by providing an ink film guide roller provided with a one-way clutch. CONSTITUTION:In a thermal transfer printer in which a ribbon cartridge is inverted to print by a printing region other than a used printing region, when a printing head is pressed against a platen 12 and is started scanning rightward, an ink film 1 passed through the printing head 11 is paid out while being taken up by a ribbon spool 2. A guide roller 14 on the payout side is provided with a one-way clutch 14a which can be rotated in the direction of the arrow but can not be rotated in the opposite direction. Therefore, a braking tension is applied to the ink film 1. When the ribbon cartridge 4 is inverted, the guide roller 14 comes to a position 14' on the take-up side. In this case, the guide roller 14' is lightly rotated in the direction of the arrow, so that it is unnecessary to increase the torque of a take-up side driving motor, and an appropriate tension can be applied to the ink film on the take-up side.

Title: Rotating shaft protector
Inventor: HAGA AKIRA
IPC: H02K11/00
Filed: 1987-01-21
Abstract: PURPOSE:To enable prevention of damage to a motor, a load and the like in case of abnormality, by detecting an increase in torque necessary for the rotation of a load shaft with a photosensor utilizing a twisting of a rotation transmitting shaft sandwiched by joint sections. CONSTITUTION:Joints 3 are so arranged as to be connectable separately to a motor shaft 1 and a load shaft 2 and a rotation transmitting shaft 6 is connected between the two joints. Light chopper blades 4 of the same shape are mounted on the shaft in the same phase. A photosensor 5 is fixed independent of the shaft 6 in such a manner to be turned ON of OFF with the blades 4. With such an arrangement, it torque necessary for the rotation of the load shaft is normal, the twisting of the shaft 6 is so slight as to obtain output signals from the sensor 5 almost completely aligned in the phase. Here, if a torque larger than the normal level is needed to rotate the load shaft, a larger shearing stress works on the shaft 5 to twist it, which causes a phase deviation in an output of the sensor 5. This deviation is detected to stop a motor thereby preventing a substantial damage to a motor or the like.

Filed: 1988-01-22
Abstract: PURPOSE:To simplify a circuit constitution, to improve a productivity and to inexpensively supply a device by directly connecting a negative-feedback circuit to a gate by means of a resistance after it passes from the drain of a field effect transistor through a between-stage capacitor for blocking a direct current and utilizing a capacity between stages as one part of the negative-feedback circuit.

A drain bias is connected through load resistances RL1 and RL2 to a drain bias terminal VDD in the same way as conventional one. Since a gate bias is connected through the feedback resistances Rf1 ad Rf2 to an input signal terminal, an input signal and a gate bias VGG are shared, the same work as conventional one is executed as the negative- feedback circuit, and a terminal exclusive-use for the gate bias of an effect transistor is not needed.
