Title: Cutting die set
Inventor: KITADA NOBUO
IPC: B23D35/00
Filed: 1989-03-06
Abstract: PURPOSE:To make it possible to release a cut piece without any resistance by holding a barstock securely only while shearing force is applied and releasing its restriction the instant cutting is terminated. CONSTITUTION:An upper cutting tool 18 is held at an upper tool rest 1, a lower cutting tool 17 is held at a lower tool rest 9, and both cutting tool move slidably and float elevatingly between a ram 19 and a table 21. The upper and lower tool rests 1, 9 are independently energized upward respectively by energizing force F1, F2 at all times. A ram clamp 4 facing the upper cutting tool 18 is energized downward by the energizing force F3, and a front clamp 11 facing the lower cutting tool 17 is energized upward by the energizing force F4. As both clamps 4, 11 are thus energized in the reverse direction to their own clamping directions, the respective openings between both cutting tools 17, 18 and between both clamps 4, 11 become large, and fluctuating elements such as the outer diameter dispersion and bending of a round barstock M provide no trouble in lateral insertion.

The resultant solution is then extruded into an alkaline coagulation bath of pH≥12, preferably ≥12.5, to coagulate a fibrous material and deposit a crystalloid therein. The resultant coagulated fibers are then treated with sulfuric acid, etc. to convert the deposited crystalloid substance into a water-soluble salt, and the fibers are washed with water, dried, drawn and heat- treated to afford the aimed fibers having cracklike hollows on the surfaces thereof due to the removal of the deposited crystalloid substance.

Title: Resistance value change detector for liquid resistor
Inventor: KUNIMI MASAKI
IPC: H02P23/00
Filed: 1986-03-14
Abstract: PURPOSE:To judge whether the resistance value of a liquid resistor is normal or not without disconnecting the resistor from a secondary circuit by supplying a current to the primary widing of an induction motor from a constant-voltage circuit at stopping time, inducing a voltage in a secondary winding, and supplying a secondary current thereto. CONSTITUTION:When the contactor 2 of a main circuit of an induction motor 4 is opened, a switching unit 3 of a constant-voltage circuit is closed to supply a current to the primary winding of the motor 4. When the current value is smaller than the current value necessary to start the motor 4, the motor 4 is not started, but stopped, and the motor 4 is regarded as a transformer. Thus, a voltage according to the winding ratio is induced in the secondary winding, and a current flows to the secondary circuit. The current is detected by a current transformer 5, and the secondary current of the transformer 5 is input to an alarm setter 6. The values corresponding to the upper and lower limits of the normal range of the resistance value of a liquid resistor 7 are set in advance in the setter 6, when it exceeds it, it is regarded as the change in the resistance value of the resistor 7 so that an alarm is output externally.

IPC: B04B1/02
Filed: 1981-04-14
Abstract: PURPOSE: To obtain the solid-liquid centrifugal separator excellent in workability and economical efficiency by a method wherein sludge accumulated in a rotor is discharged by utilizing inertia generated when the rotor is abruptly stopped to eliminate decomposition and a liquid for removing the sludge.  
     CONSTITUTION: The solid liquid centrifugal separator 1 is constituted from a rotary shaft 5 connected to a motor 4 provided to the upper part of a casing 2, a rotor 6 connected to and suspended from said rotary shaft, a brake 8 for instantaneously stopping rotation and a feed nozzle 9 inserted from the opening part 6a of the rotor. To the inner wall of the rotor 6, plural axially directed baffle plates 12 having a definite inclined angle against a center line of a radius direction are provided. As the result of centrifugal separation, sludge is accumulated to the baffle plates but, when the rotor is definitely rotated to a direction same to separation operation after stopped once to recover a liquid and abruptly stopped by the brake, sludge is moved to a rotary direction along the inner wall thereof because force is acted on the sludge to a direction inhibiting stop of the rotor and guided by forward baffle plates to be discharged to the outside through an opening 6a and a discharge port 2a.

Title: Acceleration slip control device for vehicle
Inventor: ISE SEIKI
IPC: B60T8/58
Filed: 1987-03-10
Abstract: PURPOSE:To enable preferable start of a vehicle even at a climbing road whose coefficient of friction of the road surface is low, when it is detected that the vehicle is on the climbing road and the speed is extremely low, by setting a target speed of driving wheels at a relatively low value during that period. CONSTITUTION:A driving wheel acceleration slip controlling device sets the target speed of driving wheels by a target speed deciding means based on the signal from a car body speed detecting means and a driving wheel speed detecting means and controls rotation of the driving wheels by a rotation restricting means (braking device) so that they are rotated at the target speed. Here, when the fact that the driving road of the vehicle is a climbing road is detected by a climbing road detecting means (inclination angle detecting device) and also the low speed less than the set value, namely, the starting state on a slope is detected by a low speed detecting means, the target speed detecting means sets the target speed of the driving wheels at the value lower than the usual flat road basis based on the slope basis. In this way, slip rate at the start on the slope can be controlled at low, and the vehicle can be preferably started even on the climbing road whose coefficient of friction of the road surface is low.

An informing means 400 informs the calling terminal equipment 4 a fact that reception of an ISDN number in the ISDN address has been ended, in case an inter-digit time which is counted by the time counting means 300 has exceeded the time which has been determined in advance. In case the inter-digit time counted by the time counting means 300 has exceeded continuously the time which has been determined in advance, an interface means 500 sends out a call setting request to a service integrated digital network 1, based on the ISDN address which has been received already. In such a way, the ISDN number and the ISDN subaddress can be discriminated, and an arbitrary terminal equipment can be contained in the service integrated digital network without a hindrance.

Title: Semiconductor memory
Inventor: IWAHASHI HIROSHI
IPC: G11C11/409
Filed: 1983-03-31
Abstract: PURPOSE:To reduce the precharged capacity and to lower the insant peak current by holding the electric charge when another capacity is precharged and then precharging only a selected column line with said held electric charge when row and column lines are selected. CONSTITUTION:The capacity C1 is varied by regarding the potential of a node S as logic 1 or 0 and then set at a level slightly larger than a piece of column line to be charged up to the power supply voltage VC with the precharge signal phi set at 1. Then the signal phi is set at 0 to select the row and column lines. Thus the selected column line is charged via a transistor 4 by the electric charge of the capacity C1. When the column line is discharged, a sense amplifier reads out the data of a memory cell as 0 and then detects and deliver 1 if the column line is kept in a precharge state. In such a way, the capacity C1 suffices with the value slightly larger than a piece of column line. Therefore the precharge current can be greatly reduced.
