Patent JP-S5057579-A (JP)
IPC: H01L21/52
Filed: 1974-09-11
Abstract: A flat surface of a semiconductor chip is soldered to a relatively larger flat surface of a heat sink by forming a plurality of closely spaced grooves in the flat surface of the heat sink, coating the flat surfaces of the chip and the heat sink with nickel, disposing solder between the coated surfaces of the chip and the heat sink, and heating the surfaces until the solder melts. The grooves in the heat sink prevent the entrapment of gas bubbles between the chip and the heat sink, thereby providing good thermal conductivity and a relatively low electrical resistance between the chip and the heat sink.

Title: Image-forming apparatus
Inventor: TOMINAGA HIDEKAZU
IPC: G03G15/04
Filed: 1999-04-13
Abstract: PROBLEM TO BE SOLVED: To lessen a shift of image formation positions of beams in a main scanning direction by delaying only one beam by a predetermined amount to form images. SOLUTION: A beam detector(BD) signal 11 has write position information of beams of laser lights L1 and L2 detected by one BD. A BD signal-separating means 12 extracts and separates a beam write position signal of the L1 (BD1 signal 13) and a beam write position signal of the L2 (BD2 signal 14) from the one write position information of beams of the L1 and L2. A BD1 signal delay amount-setting means 15 and a BD2 signal delay amount-setting means 16 set delay amounts separately. In this case, only one signal can be delayed. An optional delay amount is further set to each signal, and a corrected BD 1 signal 17 and a corrected BD2 signal 18 are obtained. A corrected BD signal- synthesizing means 19 synthesizes the separated corrected BD1 signal 17 and corrected BD2 signal 18, thereby forming a corrected BD signal 20.

Title: Pulsating current source
Inventor: TOOMASU HAANATSUKU
IPC: H03F3/343
Filed: 1985-05-17
Abstract: PURPOSE:To maintain the level of the DC component of a current pulse by switching the DC current from a current source through a couple of switches alternately and feeding one output back to the current source. CONSTITUTION:The current source 12 supplies the current I to a couple of switches MC0 and MC1 like FETs 13 and 14 through an input node A. The FETs 13 and 14 respond to a clock CLK and its complementary signal. Then, a current flowing through the switch MC0 is pulsating current Ip and a current flowing through the switch MC1 is fed back to the input node A. Consequently, the DC component of the current flowing through the switch MC1 (while the AC component flows to a reference point through a capacitor 16) is supplied from a point G to a point H. Consequently, the level of the DC component of current pulses is maintained.

Title: Forming method of electrode layer of flexible conductor
Inventor: OGURA KOJI
IPC: H01B1/16
Filed: 1990-04-20
Abstract: PURPOSE:To facilitate process management by covering the surface and rear faces of a conductive sheet with a support material for which an electrode paint is deposited on a transfer plate, which will be removed after the conductive sheet is cured, so as to form electrode layers on the surface and rear faces of the conductive sheet. CONSTITUTION:A support body 3 is formed by applying an electrode paint formed by dispersing silver and synthetic rubber and so on in a solvent, on a transfer plate 1 of good high temperature peeling characteristic, in a spread form. The support body 3 is installed on each of the surface and rear faces of a flexible conductive sheet 10 first cured, from the painted side, and the transfer plate 1 is removed after second curing is carried out under a condition that the support body is installed, so as to spread the electrode layer 11 on each of the surface and rear faces of the conductive sheet 10. As the transfer plate 1 of good high temperature peeling characteristic, the material for which fluorine resin is impregnated in glass cloth, and which is baked at a high temperature, is used. There is no possibility of the electrode layer 11 spread on the side of the transfer plate, since the transfer plate 1 is easily separated from a mold due to the existence of the fluorine resin. Process management is thus facilitated, and workability can be improved.

CONSTITUTION:A polysilicon layer 3 for the first gate electrode is formed by an LPCVD method while diffusing a phosphorus in SiH4-PH3-N2. The flow rate of the PH3 is altered by the thickness of the layer 3 in the LPCVD method. In other words, the phosphorus density is set to 2X10<20>cm<-3> up to 1,500Angstrom , to 4X10<20>cm<-3> up to 2,500Angstrom  and then 5.5X10<20>cm<-3> up to 3,500Angstrom  to increase the thickness, thereby increasing the flow rate of the PH3. Then, the layer 3 is anisotropically etched by plasma RIE. When the phosphorus density is varied by the thickness at this time, the electrode 3 of the first layer is tapered by etching at the end. Then, with the electrode 3 as a mask the unnecessary part of the first gate oxide film 2 is etched, and the second gate oxide films (SiO2) 5, 5' are further formed by thermally oxidizing. Thereafter, it is annealed in N2 atmosphere.
