Title: Continuous casting method
Inventor: YAMAGUCHI TAKUO
IPC: B22D11/112
Filed: 1988-02-22
Abstract: PURPOSE:To prevent excess lowering of temp. at molten metal surface zone, to shorten depth of shrinkage hole and to reduce lowering of casting yield caused by cut-off of casting end part by covering the molten metal surface in a mold with exothermic agent at the end stage of continuous casting. CONSTITUTION:In the end stage of continuous casting, the exothermic agent 41 is added on the molten metal surface in the mold 31, to cover the molten metal surface with it. By this method, together with heat insulating effect of the exothermic agent 41, the excess lowering of temp. at the molten metal surface in the mold 31 can be prevented. Therefore, the depth of the shrinkage hole developed by corresponding to the molten metal part D, can be shortened. Then, the length of the end part F to be cut off caused by developing the shrinkage hole can be shortened and the lowering of the casting yield caused by cutting-off of the end part, is reduced.

Title: Driving power transmitting device
Inventor: YAMAMOTO MASAJI
IPC: B60K17/348
Filed: 1988-02-22
Abstract: PURPOSE:To simplify constitution by connecting one of a pair of cam engagement bodies with a rotary shaft and fitting the other with the rotary shaft, permitting a relative revolution, and by forming the cam engagement body into a cam shape consisting of an inclined surface inclined in the revolution direction and an engagement surface perpendicular to the revolution direction. CONSTITUTION:For the positive input torque in which a torque is transmitted from a front wheel side drive shaft 15, the relative revolution speed between the drive shaft 15 and a rear wheel side drive shaft 16 increases, and the frictional engagement of a multidisc clutch 25 increases, and the transmission torque becomes over a bias set by a belleville spring 35. Then, a pair of cam engagement bodies 31 and 33 relatively revolve, and are relatively shifted in the axial direction by the cam action due to an inclined surface 34A. Therefore, an outer plate 37 and inner plate 38 are set into nearly directly connected state. On the contrary, for the reverse input torque in which a torque is transmitted from the drive shaft 16, the relative revolution between a pair of cam engagement bodies 31 and 33 is suppressed by an engagement surface 34B, and the transmission torque by the multidisc clutch 25 becomes relatively low because of an oil pressure generating means 23 only.

Title: Semiconductor circuit
Inventor: NANBU HIROAKI
IPC: H03K19/018
Filed: 1994-03-10
Abstract: PURPOSE:To prevent the increase of the consumption power by allowing the through current to a CMOS circuit and to prevent the deterioration of the speed of an ECL circuit. CONSTITUTION:The level of a signal OL outputted by an ECL circuit (OLI, OL2,... OEL or the like) is controlled by the power supply voltage VSS of the CMOS circuit driven by the ECL circuit. The level VBB of the input reference potential of the ECL circuit is controlled by the power supply voltage VBB of the CMOS circuit which drives the ECL circuit. Thus, the relative electric potential relation between the L level VLE of the signal to be outputted from the ECL circuit and the power supply voltage VSS of the CMOS circuit can be kept constant so that the NMOS in the CMOS circuit is turned on and the through current passes in the CMOS circuit, resulting in preventing the increase of the consumption power. The relative electric potential relation between the input reference potential VBB of the ECL circuit and the power supply voltage VSS of the CMOS circuit can be almost constant so that the deterioration of the speed of the ECL circuit can be prevented.
