Abstract: PURPOSE:To improve the air permeability of a packed layer and to accelerate a sintering speed by ejecting powder fluid of a sintering accelerator to above from the lower part of the packed layer at the time of charging raw materials to be sintered to a sintering pallet of a lower suction type sintering machine. CONSTITUTION:The raw material 1 which are to be sintered and consist of ore, limestone, coke and returns are charged onto the sintering pallet 12 of the lower suction type sintering machine to form the packed layer 5. The sintering accelerator 14 consisting of one or >=2 kinds among powder coke, powder limestone and powder iron ore is fed out of a hopper 15 and is once charged into a surge hopper 16; thereafter, the sintering accelerator is transported into a powder fluid pipe 17 by the air force fed from a gas ejection blower 13 and is ejected from a powder fluid ejection part 18 to the lower part of the packed layer 5 at this time. The amt. of the sintering accelerator 14 to be mixed with the gas is confined to about <=3% of the raw materials 1 to be sintered and the ejection rate of the gas is specified to about 0.3 to 2.0m/sec. As a result, the air permeability of the packed layer 5 is improved, by which the sintering speed is increased and the productivity and the yield are simultaneously improved.

Filed: 1986-08-11
Abstract: PURPOSE:To expand the composition range of a metal sintered body and enable easy weld by welding a steel foundation to the metal sintered body combined with cemented abrasive grains via a metal layer mainly consisting of Ni or Fe. CONSTITUTION:A steel foundation 1 and a sintered metal 2 combined with cemented abrasive grains such as diamond and CBN are monolithically welded to each other via a metal layer 3 of Ni or Fe. This Ni or Fe will do even if impurities and additives are contained therein within an acceptable range. And in welding the foundation 1 to the metal 2, when a metal piece 3' such as Ni is placed between a foundation metal 1' and a sintered metal 2', and has been applied with a current for pressure welding, resistance heating welding progresses smooth, thereby restraining the occurrence of a brittle alloy phase. Consequently, weld quality is improved, the composition range of the sintered metal is expended and welding work becomes easy.

IPC: G11C16/06
Filed: 1982-10-29
Abstract: PURPOSE:To reduce the power consumption of an EPROM device by providing a parasitice MOSFET having its gate insulated film made of a field insulated film, the 1st and 2nd inverters and a reference voltage generating circuit which produces the writing voltage equivalent to the breakdown voltage of the drain junction of a storage element. CONSTITUTION:The threshold voltage is set at about 14V for an MOSFETQ11 having its gate insulated film made of a field insulated film 2. In a writing mode where the writing control signal we is set at an ''L'', an MOSFETQ16 is turned on and off in accordance with a signal din. Then the writing voltage is supplied to a common data line CD. As a result, a writing operation is carried out to a selected FAMOSFET. In a reading mode, 5V is applied to a terminal VPP. Thus the FETQ11 is turned off with outputs of inverters IV1 and IV2 set at an ''H'' and the ''L'' respectively. Thus an MOSFETQ13 is turned off. The signal we is set at the ''H'' with the FETQ16 turned on during a reading action. Therefore no direct current is left conducted continuously from the output of a reference voltage generating circuit Vr-G through the FETQ16 which is kept on.

Title: Magneto-optical head
Inventor: KATASE YOSHIHIRO
IPC: G11B11/105
Filed: 1986-08-15
Abstract: PURPOSE:To prevent the stopping performance of an objective lens from being deteriorated by arranging a 1/2 wavelength plate in an optical path from a light split means till a detecting means so as to prevent a luminous flux projected onto a magneto-optical disk from being transmitted through said 1/2 wavelength plate. CONSTITUTION:While the upper half of the luminous flux 10 is made incident in a polarized plate 15 without being transmitted through the 1/2 wavelength plate 12, the lower half of the luminous flux 10 is made incident in the polarized plate 15 after being transmitted through the 1/2 wavelength plate 12. Thus, a reproducing signal is obtained from the sum and the difference of output signals between 2-split regions 16a, 16b and 16d, 16e, that is, from a differential output. Since the 1/2 wavelength plate 12 is arranged in an optical path between the light separating means and the detection means and the luminous flux projected onto the magneto-optical disk 7 does not transmit through the 1/2 wavelength plate in this way, the stopping by the objective lens 6 is not deteriorated.

Title: Anti-lock brake control system
Inventor: MURAKAMI KOJI
IPC: B60T8/72
Filed: 1984-09-12
Abstract: PURPOSE:To shorten the braking distance by executing pressurizing control with correspondence to the variation of wheel speed for every predetermined time on the basis of the wheel speed at the point where the speed will increase after temporal deceleration due to reduction of braking pressure for the purpose to avoid locking immediately after braking. CONSTITUTION:Upon stepping of brake 7, predetermined signal is provided from brake signal processing section 8 to drive the wheel drive section 10 through MPU5 thus to start braking. Consequently, MPU5 will operate the difference between the wheel speed detected through car speed detecting section 3 and referential speed or the differential deceleration and upon exceeding of said difference over preset threshold, the wheel control section 10 is controlled to reduce the braking pressure thus to avoid initial lock. While the wheel speed at the point where the speed will start to increase is employed as a referential speed to obtain the difference against the wheel speed and upon lowering of the difference below a threshold determined on the basis of the referential speed, the braking pressure is increased again.
