Title: Preparation of hybrid cell
Inventor: YAMAGUCHI TAKASHI
IPC: C12N5/14
Filed: 1989-06-30
Abstract: PURPOSE:To apply a fusion operation to all plants without limiting the plants and effectively prepare a hybridoma cell by a simple means by subjecting two kinds of plant protoplasts to the fusion operation in a state that one of two kinds of the plant protoplasts is immobilized. CONSTITUTION:One kind of protoplasts A to be fused are adhered to a lectin- immobilized flat plate through the lectin so that the protoplasts A do not contact with each other. The lectin immobilized on the flat plate is substituted with a solution containing 10-100mM of a hapten saccharide to weaken the affinity of the lectin. Another protoplast B suspended in a solution containing 10-100mM of the hapten saccharide is placed on the flat plate. On a fusion operation in that state, AA do not fuse with each other because of not enabling to contact with each other but only AB and BB contact with each other to cause fusions between AB and between BB. When the flat plate is washed, the BB is washed out because of being not immobilized on the flat plate and only protoplast, heterokaryon, produced between the AB, remains on the flat plate, thereby permitting to prepare a hybrid cell.

Title: Flip chip packaging
Inventor: SAKO YUKITOSHI
IPC: H01L23/28
Filed: 1998-06-16
Abstract: PROBLEM TO BE SOLVED: To improve mechanical strength of a PCB or a FPC around an IC chip, by subjecting an packaging area of the PCB or the FPC 4 to a plastic working in the portion around a region where the IC chip is packaged. SOLUTION: When a bump 2 is joined to a PCB or an FPC 4, an ACF 3 contains a thermosetting adhesive and hence is heated and pressed. In this case, since the connection of an IC chip 1 to the PCB or the FCP 4 is ensured only by the ACF 3, the ACF 3 receives all the stresses applied to a module after flip chip packaging such as bending, shearing, torsion and compression. Therefore, to improve mechanical strength, an packaging area of the PCB or the FPC 4 is subjected to plastic working in a shape of letter U, in the portion around a region where the IC chip is packaged. This can produce a module with good reliability and mechanical performance endurable to various working after packaging.

Title: Motor inspecting device
Inventor: SAWA KYOJI
IPC: G01R31/34
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To surely judge the quality of a motor by applying an operable lowest voltage to the motor by a voltage applying means to slowly rotate an oscillator, and detecting the rotation stop of the oscillator by a stop detecting means. SOLUTION: A control box 15 measures the current value carried between an oscillator 11 and a guide pin 6. When a motor 9 is normally driven, and the oscillator 11 and the pin 6 keep the contact state, a prescribed quantity of current can be measured by the box 15. When the motor 9 stops to drive, and the oscillator 11 is separated from the pin 6, the current quantity measured by the box 15 is 0 A. When the current quantity is not 0 A, it is judged that the motor 9 is normally driven to light a green lamp 16. Since an operable lowest voltage is applied to the motor, the oscillator is slowly rotated. In this case, when a shaft can not be smoothly rotated by the failure of the motor, the oscillator is stopped. Thus, the quality of the motor can be judged by detecting the stop of the oscillator by a stop detecting means.

Abstract: PURPOSE:To prevent improper reading, by providing an adjusting member whose one end is in contact with an original placing plate so as to scan a reading section while keeping the distance between the original table and the reading section to a prescribed value. CONSTITUTION:The original table 11 and a slide shaft 15 deform, because the distance between the slide shaft 15 and the upper end of a distance adjusting member 25 is unchanged and a roll 28 of the distance adjusting member 25 moves in contact with the original table 11 while being rotated if the distance between the slide shaft 15 and the back side of the original table 11 is shorter than the distance between the slide shaft 15 and the distance adjusting member 25. Further, the distance between the slide shaft 15 and the rear side of the original table 11 is made spread to the same value as that between the slide shaft 15 and the upper end of the roll 28. That is, the distance to the reading section 14 is kept to a prescribed dsitance. Since the front and rear ends of the table 11 are fixed, the original table 11 is mainly deformed at the running of a box 13, rather than the slide shaft 15 so as to keep the distance to the prescribed value.
