Title: Taping method of semiconductor device
Inventor: YAMAMOTO YUKI
IPC: B65B15/04
Filed: 1992-01-30
Abstract: PURPOSE:To reduce adjustment during bonding of a cover tape and diminish tape breaks due to dispersion in the bonding strength between a cover tape and a carrier tape. CONSTITUTION:After a semiconductor element 2a is inserted in a carrier tape 1a, a cover tape 3a composed of only polyethylene layer 5a is pushed by a roller 7a to cover a hole in the carrier tape 1a and then a cover tape 4a consisting of an adhesive layer 6a and a polyethylene layer 5a is pushed and adhered on the carrier tape 1a by the roller 7 to obtain taping function. Thereby, adjustment during bonding of the cover tape on the carrier tape can be reduced and the dispersion in the bonding strength is diminished, resulting in a reduction of tape breaks.

Filed: 1991-02-14
Abstract: PURPOSE:To realize a control method giving superior image quality by cutting off feeding of developer to a developing roll by stopping rotation of a feeding roll and continuing rotation of the developing roll when there is a necessity to evade a magnetic brush formed on the developing roll from coming into contact with a photosensitive body. CONSTITUTION:The toner image 3 is formed by a first developing device A, electricity feeding to a driving motor 12 is stopped before it passes the vicinity of a developing roll 5, and rotation of the feeding roll 8 and an agitation roll 9 are stopped, and the feeding of the developer 15 to the developing roll 5 is stopped. On the other hand, energizing of the driving motor 10 is still continued, and the developing roll 5 is rotated at the same speed.

Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent clogging by pumping drain into a pumping pipe, and disposing a scale removal chemical agent tank on the most upstream side of the pumping pipe in the case of draining. SOLUTION: A pumping pipe 3 is connected to a conveying pump 2 connected to a toilet stool 1, a chemical agent tank 4 is connected to the most upstream side of the pipe 3 through an injection pipe 5, and a check valve 6 is provided in the pipe 5. When the pump 2 is actuated, drain is pumped in the pipe 3, negative pressure is produced in the pipe 3 by the velocity of drain, acts on to open a valve 6, and a chemical agent D in the tank 4 is sucked into the pipe 3 through the pipe 5. At this time, a constant quantity of the chemical agent D is automatically drawn in the pipe 3, and scale adhering to the inner wall of the pipe 3 is removed. Since the constant quantity of the chemical agent D is gradually injected into the pipe 3 in proportional to operation frequency of the pump 2, the more sewage is increased, the more the quantity of the chemical agent is increased.  Thereby scale can be surely removed.

Abstract: PURPOSE:To eliminate the nonspecific antigen-antibody reaction arising from the aging of fowl so that antibody measurement with high sensitivity is enabled by acting a surfactant directly on fowl infectious laryngotracheobronchitis (ILT) virus, thereby providing an antigen. CONSTITUTION:A sample to be inspected is acted on the antigen formed by acting the surfactant directly on the ILT virus and the antibody labeled with biotin is brought into contact with the antibody; thereafter, a labeling enzyme conjugated with avidin is acted thereon.
