Title: Rubber stress cone
Inventor: ISAKA MUNEHARU
IPC: H02G15/24
Filed: 1989-05-11
Abstract: PURPOSE:To facilitate installation work by adding shape-memory resin into the material of a semiconducting layer and a rubber insulator to form a rubber stress cone, and after that, by expanding a diameter of a fitting hole into which the joints and end sections of a cable are fitted. CONSTITUTION:A rubber stress cone 1 added by shape-memory resin is set into the initial fitting hole bore (original diameter). After that, under this condition the bore of each rubber stress cone 1 is forcibly expanded with a diameter expander in structure where the ring section at the tip is constituted to expand the diameter, and is cooled as it is. Silicon oil is then applied to the insulator of a high voltage CV cable, into which the rubber stress cone 1 is inserted. The rubber stress cone 1 is then heated at about the same temperature when the diameter was expanded and contracted to the initial original diameter when the rubber stress cone 1 was moulded. With this contraction the rubber stress cone 1 can extremely firmly installed to the cable insulator.

Title: Production of coal-water slurry
Inventor: KANEKO SHOZO
IPC: C10L10/14
Filed: 1987-05-18
Abstract: PURPOSE:To produce the title slurry which has excellent storage stability free from precipitation and coagulation, by incorporating an anionic additive and a nonionic additive at respective pulverization steps meeting the characteristics thereof. CONSTITUTION:Coals 1 and water 2, together with an additive 4, are fed into a mill 7 by means of a screw feeder 6. In the mill, the coals are pulverized, thereby obtaining pulverized coals. The additive adheres to the surface of the pulverized coal particles, thereby contributing to the prevention of coagulation of pulverized coal particles and increasing the coal concn. The interior of the mill 7 is partitioned by means of a diaphragm 8 into a plurality of chambers, and an optimum combination of ball diameter, ball mixing and ball packing ratio is selected. As an additive 4 to be fed into the inlet side of the mill, a nonionic additive which is inferior in temp. resistance but superior in thickening capability is used since the interior of the mill is in a low-temp. region. On the other hand, as an additive 12 to be fed into the outlet side of the mill, an anionic additive having excellent temp. resistance, durability and stability is used since the interior of the mill is in a high temp. region. By the above method, a coal-water slurry which has improved storage stability free from precipitation and coagulation of pulverized coals, as compared with that of the conventional slurry obtd. by using only a single type of anionic additive, is produced.

Inventor: NAKAYAMA TOMOFUMI
IPC: B65H7/06
Filed: 1986-05-26
Abstract: PURPOSE:To highly accurately control a resist clutch, by installing two timers and one latch to a resist control circuit. CONSTITUTION:By giving different reference clocks to two timers 13 and 14 and causing them to count up independently, the ON/OFF control of a resist clutch 10 is performed. On the other hand, when an abnormal state, such as jamming, occurs, the ON/OFF control of the resist clutch 10 is performed by means of a latch 15 independently from the operations of the timers 13 and 15. Therefore, when the timer values which turn ON/OFF the resist clutch 10 are set, the resist clutch 10 can be controlled. Moreover, since hard timers are used, reference frequencies are not omitted and highly accurate resist control can be performed.
