Title: Epoxy resin composition for semiconductor sealing
Inventor: FUJII MASANOBU
IPC: C08L63/00
Filed: 1992-02-14
Abstract: PURPOSE:To improve a laser markability and the reliability of a semiconductor device by a method wherein a specified amount of a carbon black only is blended in an epoxy resin composition for semiconductor sealing use as a coloring agent. CONSTITUTION:An epoxy resin composition for semiconductor sealing use is formed containing 0.01wt.% or higher and less than 0.2wt.% of a carbon black only as a pigment. Thereby, the contrast between a destructed part and a non-destructive part due to a laser becomes clear and a marking becomes clear. As the composition does not contain an azo-containing metal dye and other organic dye, a semiconductor device covered and molded with the resin composition is obtained as one having a superior reliability (a humidity resistance). It is obvious hat this composition containes a normal curing agent, a curing promotor, a filler and other additive according to the need. In respect to a laser mark property a marking is put on the surface of an obtained package with carbonic acid gas to evaluate the laser markability by visual observation and in respect to the humidity resistance a TEG of an aluminium wiring of 10mum is assembled, is left to stand at two atmospheric pressures at 121 deg.C and the humidity resistance is estimated in a time at the time when the TEG reaches 50% of a cumulative defective fraction.

Abstract: PURPOSE:To perform an optimum oil level equalizing operation by alternating a normal operation, a first oil level equalizing operation and a second oil level equalizing operation while both compressors are being operated, and the operating frequencies of the compressors are relatively increased and decreased during the first and second oil level equalizing operations so that the lubricant in the compressor casing of the compressors may be efficiently transported through an oil equalizing pipe. CONSTITUTION:While compressors 1, 2 are both being operated, the outdoor control section 50 causes an alternating repetition of a normal operation in which the compressors 1, 2 are operated nearly at the same operating frequencies, a first oil level equalizing operation in which the operating frequency Fa of the compressor 1, for instance, of either one of the compressors 1, 2 is increased and decreased relative to the operating frequency Fb of the compressor 2 while the operating frequency Fb of the compressor 2 is maintained at a constant level Fb0, and a second oil level equalizing operation in which the operation identical to the first oil level equalizing operation with the role of the compressors 1, 2 reverted is performed. During the first oil level equalizing operation, the operating frequency Fa of the compressor 1 is reduced. As the pressure in the casing of the compressor 1 becomes higher than that of the compressor 2, the lubricant in the casing of the compressor 1 gradually flows into the low pressure side casing of the compressor 2 along with the refrigerant through an oil equalizing pipe 45.

Abstract: PURPOSE:To substitute the opening operation of a chucking lever by a linkage by providing an opening pin to the bottom end of a cylindrical rod, which allows an opening lever to rotate freely. CONSTITUTION:A linkage comprises an opening pin 3 arranged to the bottom end 2a of a cylindrical rod 2 which can slide up and down and an opening lever 6 is arranged rotatably thereby. When the cylindrical rod 2 goes down to lower the opening 3, the opening lever 6 swings regarding the pin 3, and a rolling element 7 rotates regarding a linking shaft and also rolls in a hole 5. Then, the distance between the center of the linking shaft (or the rolling element 7) and that of the cylindrical rod 2 becomes longer and the position of the hole 5 of a chucking lever 4 is changed. At the result, the chucking lever 4 rotates regarding a rotatable pin 23 in a housing 25 and opens. By thus adopting the linkage for the opening operation of the chucking lever 4, the part where metallic parts are rubbing are removed and the influence of friction can be eliminated.

     CONSTITUTION: The gate-source voltage is referred to as VG, and the drain voltage is VD. IN this case, ΔVD 1  =VD 1  - VD 2  - R{(ID 1  - ID 2  - (ID 1 ' - ID 2 )} can be obtained when VG-VG' is small and based on VD 1  ≈ (VG - VG')g m R, VD 2  ≈ (VG - VG')g m R, g ml  = (ID 1  - ID 1 ')/(VG - VG') and g m2  = (ID 2  - ID 2 ')/(VG - VG'). Both the 1st and 2nd members within { } are positive or negative, and the parallel property can be expressed with ΔVD. And if the Ib-VG characteristics is parallel between two units of FET, the inside of { } becomes O. An extremely good correlation is obtained between ΔT and ΔVD which are measured actually with variation of the temperature. Then ΔID' is calculated with same VG and based on drain current difference ΔID and VG'. Thus, ΔVT can be measured quickly and in a high accuracy under the normal temperature based on ΔID - ΔID' and according to the correlation diagram.

Title: Parallel feed copying machine
Inventor: ARAI ATSUSHI
IPC: B65H5/00
Filed: 1985-02-19
Abstract: PURPOSE:To enable the copying speed to be increased while the image processing speed is kept constant by feeding two pieces of transfer paper in parallel each other with a small gap provided between them simultaneously from either numbers of feeders or one feeder which is divided into two, in such a way that one of transfer paper is shifted from the ordinary reference point. CONSTITUTION:When numbers of transfer paper are fed simultaneously, they 50 and 51 are arranged in parallel each other with a gap delta provided. That is, the transfer paper 50 is fed from No.1 tray 33, and the other transfer paper 51 is fed from No.2 tray 34. In setting the transfer paper 50 and 51 in the trays 33 and 34, the transfer paper 50 is set based on the reference point B which is used for an ordinary copying. And for No.2 tray 34, a reference point A is set in such a way that the gap delta has been provided from the beginning. This allows a transferred image to be dislocated by the quantity of delta from the subject copy. However, this may be negligible if the gap delta could be made sufficiently small. In the actual case, this space is in the margin for seam where no image is normally printed. This configuration prevents the transfer paper from being overlapped, skewed, jammed, and shrinked.
