Inventor: MIZUNUMA SUSUMU
IPC: B30B11/00
Filed: 1990-04-26
Abstract: PURPOSE:To find out a friction coefficient mu(= F/P) by measuring force P vertical to the wall face of a movable die which is received from powder in the die and frictional force F in the wall face in a pressing direction by a cell fixed to the die. CONSTITUTION:At first, press stress (f) is applied from the rear face of the movable die 2 to contact faces 7, 7' and 8, 8' between the die 2 and a die body 1. In said state, the face pressure P is set up to '0'. When operation conditions are controlled so that the friction coefficient found out by said procedure and a stress-strain relational curve found out by a known method are always constant, molded product having the same density distribution can be obtained. When temperature distribution for sintering is controlled to a constant state, products having the same shape and size can be obtained. In said procedure, the friction coefficient and stree-strain relation can easily be related to various process dominant factors such as the material characteristic values of powder and die conditions.

Title: Semiconductor device
Inventor: OHORI TATSUYA
IPC: H01L29/778
Filed: 1986-05-13
Abstract: PURPOSE:To prevent the deterioration and to obtain a stable characteristic, by laminating AlxGa1-xAs in the sequence of natural spacers of 0.2<=x<=4 and 0.8<=x<=1, an electron donating (n) layer of 0.8<=x<=1 and an (n) layer of x<=0.2 in l device of CaAs/Al GaAs. CONSTITUTION:First a natural AlxGa1-xAs spacer 3a is formed in two layers, and the mixed crystal ratio of a layer 3a1 in the Vicinity of a junction with natural GaAs 2 producing two-dimensional gas is set to be 0.2<=x<=0.4, while said ratio of an upper layer 3a2 is set to be 0.8<=x<=1. Thereby the upper layer is made to have a smaller electron affinity than the layer 3a1, not to cause a DX center (in other words, conduction electrons do not fall to a donor level even when shielded from light) and to reduce activating energy. An AlxGa1-xAs electron donating layer 36 is formed also in two layers, and a layer 3b1 on the layer 3a side is made to have the mixed crystal ratio of 0<=x<=1, to have a small electron affinity, not to let a donor impurity cause the DX center but to let it supply carriers of high concentration while not varied with temperature. A layer 3b2 is provided for protection, and the mixed crystal ratio thereof is set to be x<=0.2. It is stable even when exposed to the air, not causing the DX center and reducing the activating energy. According to this construction, the DX center is not caused in each AlGaAs layer, and a layer having a large mixed crystal ratio of Al is not exposed. Therefore, the deterioration is prevented, and the characteristic is made stable.

Abstract: PURPOSE:To shorten time required for heat-welding a film to simplify manufacturing by peeling a back liner at a portion to be heat-welded from an inner pad by means of water repellent agent in a manufacturing process of a cardboard. CONSTITUTION:Each cardboard F cut into a required length for box assembly is provided with a fold by a pressing blade 17 at a predetermined position by a press-molding machine, and at the same time a surface liner 2 and an inner pad 1 at a portion to be heat-welded are cut by a cutter blade 19. At this portion to be heat-welded, an end 20 of the inner pad 1 and the surface liner 2 is left unadhered to a back liner 3 by means of water repellent agent, so that the end 20 can be removed only by making a cut, thereby saving trouble of peeling off adhered portions. Then a parallelopipe is structured as a previous stage no box assembly, wherein a two-fold outer piece 27a of a coupling piece 27 is first heated from a side of the back liner 3 to have it heat-welded to an opposite side, and then an inner piece 27b is adhered to the outer piece 27a with starch paste or the like. Thus heating required for heat-welding can be efficiently performed.

Title: Constant current circuit
Inventor: MABUCHI HIROSHI
IPC: G05F3/22
Filed: 1986-05-15
Abstract: PURPOSE:To drive a load by a stable current by controlling the current of an output transistor drive current source with the aid of a difference signal between a load current taken out of an output transistor and the current of a reference current source. CONSTITUTION:Since there is one transistor 5 in a reference current monitor circuit 23 connected to the transistor 1 of the reference current source 20, its base current can be neglected, and a reference current I1 becomes equal to a collector current I1' accordingly. Since a load current I2 to drive a load 3 and the collector current I2' of a transistor 10 comprising of a load current monitor circuit 22 share the output transistor 2 and a base, they are equal. Due to feedback, a differential amplifier 24 acts as equalizing the base input potentials of transistors 6 and 7. Where the values of resistances 11 and 15 are equal, the collector currents I1' and I2' of transistors 5 and 10 become equal, and the reference current I1 and the load current I2 also become equal.
