Title: Driving method of ink jet device
Inventor: CHIYOU KIMEI
IPC: B41J2/055
Filed: 1993-09-09
Abstract: PURPOSE:To reduce driver circuits and patterns to a large extent to relax cross talk and to eliminate the generation of an accidental drop or the mixing with air bubbles. CONSTITUTION:When the injection of ink from the odd number-th ink chamber 4a1 of an A-group is not performed, a brake pulse is applied to an ink chamber 4b1 in the same first timing as a drive pulse. Therefore, the potential difference on both sides of a partition wall 6a1 is kept zero and the partition wall 6a1 is not deformed and no ink is emitted from an ink chamber 4a1. At this time, potential difference is generated in a partition wall 6b1 and the partition wall 6b1 is deformed toward the interior of an ink chamber 4c1 but, since no drive pulse is yet applied to the even number-th ink chamber 4a2, the partition wall 6c1 is not yet deformed and the generation of an accidental drop from the ink chamber 4c1 is suppressed.

Title: Torque sensor
Inventor: ARAKI MASATO
IPC: G01L3/10
Filed: 1989-09-01
Abstract: PURPOSE:To measure the torque of a prime mover with high accuracy without contacting by removing residual stress which is generated when amorphous metal is joined with a metallic round rod by explosive press-contacting by a heat treatment. CONSTITUTION:A metallic plate-amorphous metal joined body as a sensor element is formed by welding the amorphous metallic foil 1 to a disired part of the surface of a metallic column with explosion pressure. Then the joined part is cut in a partially sectorial shape along radial cutting lines having their center at the axis of the metallic column and then cut perpendicularly to desired length along the axis of the metallic column. Consequently, the shape of the plane where the amorphous metallic foil 1 is joined in one arcuate surface is almost rectangular. Then stress relief annealing is carried out and the compressive stress generated at the amorphous metallic part by the stress relief annealing is reduced by elastic-plastic deformation working; and then the obtained element is fitted to a fitting seat (mount) 3' to constitute the sensor. Consequently, the torque of the prime mover can be measured with high accuracy without contacting.

Title: Semiconductor device
Inventor: UCHIDA HIROFUMI
IPC: B29C45/14
Filed: 1990-08-27
Abstract: PURPOSE:To suppress voids on the side face of a semiconductor chip from forming when packaging it through a transfer molding method, by mounting the semiconductor chip on a die pad so that its at least one predetermined side are placed on or outside the corresponding end side of the die pad. CONSTITUTION:A side 22a of a semiconductor chip 22 is placed on the opposite side to a gate 24 of the chip 22 for implanting a resin into the chip 22. The chip 22 is so bonded to a die pad 21 from above that the side 22a is protruding outward from a end side 21a of the die pad 21 corresponding to the side 22a. Therefore, the generated voids can escape very easily before a transparent resin is hardened. As a result, in a transfer molding method, the voids on the side of the semiconductor chip can be suppressed surely from forming. But, when the chip 22 is bonded to the die pad 21 from above, the quantity of a bonding agent is so adjusted that it is not protruding from the die pad 21 to the outside. Thereby, the reliability of semiconductor devices is improved, and in an optical semiconductor device, particularly, the yield associated with badness in appearance can be improved to a great extent.
