IPC: H01L21/822
Filed: 1987-04-24
Abstract: PURPOSE:To improve the voltage dependence of a resistance value without lowering the sheet resistance by a method wherein, in the neighborhood of a junction formed between a diffusion layer and a semiconductor substrate, the concentration of an impurity of a conductivity type contained in the substrate is made higher than other parts. CONSTITUTION:A p-type impurity diffusion region 5 is obtained after an ion- implantation process to decide a resistance value is executed onto a semiconductor substrate 1 two times. As a first ion-implantation process, e.g. arsenic is implanted and driven in in such a way that a concentration profile of an impurity as indicated by a symbol 101 is obtained. In succession, ions of an impurity whose conductivity type is opposite to that for the first ion-implantation process, e.g. boron, are implanted and driven in in such a way that the concentration profile of the impurity as indicated by a symbol 102 is obtained. Accordingly, a distribution of the total concentration of the impurity becomes the distribution which is close to a steep stepped junction as shown by a symbol 100; when a reverse bias is impressed, the distribution is extended toward a p-region near a p-n junction; a cross-sectional area of a resistance region is made small, the occurrence of a speed change layer is suppressed; accordingly, a semiconductor resistor whose voltage dependence is good, in other words small, is obtained.

Abstract: PURPOSE:To permit transportation of a plural kinds of coil bobbins by a same pallet by setting the diameter of the collar on one edge side of a different kind of coil bobbin smaller than the diameter of the holding hole on a pallet, forming a step difference. CONSTITUTION:In order to transport a different kind of coil bobbin, the diameter (l3) of a collar 2' on one edge side of a coil bobbin 1' is set smaller than the diameter (l2) of the holding hole 4 on a pallet 3, and said one-edge side is inserted into the holding hole 4 on the pallet 3.

When the air hole 4 is closed and the air inlet 8 opened, a normal operation can be performed. When only the fan 5 of the indoor unit is operated with the air inlet 8 closed and the air hole 4 opened, cold air under the floor is taken in to the room via the air hole 4. Further, cold air under the floor is taken in to the room naturally when the indoor unit B of air conditioner is stopped, the air hole 4 opened and the air inlet 8.

Abstract: PURPOSE:To provide a drawing device which is applicable to >=3 strands by permitting free extension and contraction of a gear coupling which connects worm reduction gears of fixing and press-fitting sides rolls which sandwich and draw a billet and fixing freely slidably the torque arm of the latter reduction gear. CONSTITUTION:A billet 12 is sandwiched and drawn by fixing and press-fitting side driving rolls 17, 18. Both rolls are driven by respective worm reduction gears 21, 22 connected by a gear coupling and a spindle 26 which is connected to the latter and extends approximately to the press-fitting direction. The coupling 23 is made freely extensible and contractable in the press-fitting direction. Torque arms 33, 34 are fixed to the case of the reduction gears 21, 22 and the arm 34 is fitted freely slidable in the press-fitting direction to a stopper 37 fixed to the frame 16 of the roll 18. Then the gap between the rolls 17 and 18 fluctuates and th coupling 23 extends or contracts as well and since the arm 34 slides with respect to the stopper 37, the fluctuation in the roll gap is absorbed. The interference of the spindle 26 is obviated even in the case of >=3 strands.

Abstract: PURPOSE:To enhance the heat transfer rate of a fin by separating a fin provided in the periphery of a rotating electric machine into the upstream side and the downstream side of cooling air to generate a front edge effect in the fin end surface part of a separation part. CONSTITUTION:In order to cool the peripheral part 3-1 of a frame 3, cooling air (A) generated by a fan 5 is sent to the peripheral part 3-1 of the frame 3 by a fan cover 8. A fin 4 provided in the peripheral part 3-1 of the fan cover 8 is separated into an upstream side fin 4-1 and a downstream fin 4-2. As a result, cooling air A1 flowing between the fins hits against the end surface 4e of the downstream fin 4-2, and the flow of the cooling air A1 is thrown into disorder by a front edge effect to enhance a heat transfer rate. Also, the cooling air A1 is made to branch out into cooling air A1-1 and cooling air A1-2. Thereby, even when there is a place in which the cooling air is hard to flow between the fins of the upstream side, the distribution of the cooling air between the fins 4-2 of the downstream side is uniformalized.
