Filed: 1992-08-14
Abstract: PURPOSE:To efficiently cool an entire nozzle by bringing, when a heat-curable resin is molded by a split mold and a covering material is poured from a nozzle provided at one mold, an entire surface of a foremost end of the nozzle into contact with a sliding surface of the foremost end of a nozzle mounting cavity, and allowing a cooling medium passage to remain between the other part and the inner periphery of the cavity. CONSTITUTION:A coolant passage 5 is internally provided at a base of a nozzle body 4. A nozzle discharge part 4b is divided into a side 4b1 near the base of the nozzle and a foremost end side 4b2 as a nozzle, the 4b1 is formed in a small diameter to form a space S4 from an upper mold 1, and the side 4b2 is brought into contact with the sliding surface with respect to the entire inner periphery of the foremost end of the cavity. A plurality of cutouts 6c are formed at a coupling part to the side 4b1 to form a space S5, and the spaces S3, S4, S5 are connected. Thus, the body 4 is so formed as to be freely inserted and removed. Thus, when cooling medium (air) is press-fitted from an end in the space S4, the air is again fed to the space S4 and again discharged from the S5.

Title: Centrifugal dehydrator
Inventor: ARAKI KOJI
IPC: D06F49/04
Filed: 1991-08-28
Abstract: PURPOSE:To keep dewatering rate constant by repeating temporary stop of driving of a motor four times at the time of starting dewatering operation and prolonging the dewatering time set on a timer of the sum of inertia rotational speeds of a dewatering vessel is smaller than a preset value. CONSTITUTION:When an electric current is applied to a motor 8 to rotate a dewatering vessel, and in the lapse of eight seconds, the application of an electric current is cut off for three seconds, the dewatering vessel continues rotation by inertia. The intermittent dewatering is repeated four times. After that, the dewatering time is inputted in a micro-computer control portion 2 from a memory, and the sum of pulse signal numbers counted during the respective intermittent dewatering operations is compared with a preset value by a comparing means 11. If the sum is more than the preset value, the dewatering time is set on a timer 10, if less, the time obtained by adding one minute to the dewatering time is set on the timer 10, and the dewatering operation is started. When the timer 10 counts up, the dewatering operation is ended. Thus, when the inertia rotational speed of the motor 8 is small, washing in the dewatering vessel is judged to be biased, and the dewatering time is prolonged so as to obtain the same dewatering rate as that of normal dewatering operation.

Title: Apparatus for measuring effective flexural rigidity of guide rail of elevator
Inventor: KAGAMI MASAAKI
IPC: B66B5/00
Filed: 1990-08-21
Abstract: PURPOSE:To measure effective flexural rigidity simply with relatively good accuracy by applying vibration force to a guide rail in a direction perpendicular thereto and by measuring natural frequency of lateral vibration of the guide rail at this time. CONSTITUTION:An electric signal is sent from a control box 14 to a vibration applying device 8, which applies vibration force of variable frequency to a guide rail 1 to cause lateral vibration in a horizontal direction on the rail 1. By measuring magnitude of vibration at this time by a vibration measuring device 9, natural frequency f0 on the rail 1 is measured. Since there is correlation between the frequency f0 and a spring constant (k) of horizontal deflection, the value f0 can be converted into a constant K0. When a spring constant at an optional floor is kH, an increase/decrease of flexural rigidity can be estimated with a constant ratio kH/k0. Since in general the value f0 is proportional to a square root of the constant (k), measurement of natural frequency f0H at an optional floor position and natural frequency f00 without any compression load applied to the rail 1 permits estimation of an increase/decrease in flexural rigidity from (f0H/f00)<2> (=kH/k0).

Title: System for restoring faulty of ring lan
Inventor: OCHIAI TAMIYA
IPC: H04L12/42
Filed: 1990-08-20
Abstract: PURPOSE:To restore a node for control from a faulty state without stopping a system by doubling the node for control in such a state that management information can be transferred between the two nodes. CONSTITUTION:Monitoring packets are sent from a currently used node 100a for control at regular time intervals. Each node writes the information of a fault detected at its own node in the status bit of the packets at the packet arriving timing. When the adjacent node or adjacent ring transmission line in the forward direction becomes faulty, the currently used node 100a makes communication by only using monitoring packets arrived from the normal ring on the other side so that the said monitoring packet can travel round to the node 100a. Since packets with instructions regarding the occurrence and restoration of faults in their command bit are sent to relevant nodes after the status information of communicable nodes is collected by means of the packets in such way, control can be made in accordance with a fault restoring procedure.
