Title: Transformer for metal-based board
Inventor: TAKAGI SATOYUKI
IPC: H01F27/22
Filed: 1990-12-04
Abstract: PURPOSE:To restrain a temperature rise and to make the title transformer small-sized by a method wherein a gap is formed at the contact face of a core with a board, it is filled with a resin whose heat conductivity is high, the quantity of heat generated at a transformer for metal board use is conducted to a metal board as much as possible and heat is dissipated. CONSTITUTION:A bobbin whose winding operation and terminal installation operation have been completed is sandwiched between an upper-part core 1A and a lower-part core 1B; it is fixed by using an adhesive 3 so that the position of a core contact face 10 is not changed. A resin 12 whose heat conductivity is high and which is sufficient to fill a gap 14 formed between the core 1B and a metal-based board 6 is coated. When a transformer 13, for metal board use, which has been mounted on the board 6 is operated, the transformer 13 is self-heated. Heat regarding the core 1A out of the quantity of heat is dissipated into the air and is conducted to the core 1B through the face 10 and the adhesive 3. The heat conducted to the core 1B and the heat generated at the core 1B are dissipated into the air; at the same time, they are conducted to the board 6 through the resin 12 which has been filled into the gap 14 formed between the core 1B and the board 6. Thereby, a temperature rise is restrained, and the title transformer can be made small-sized.

Title: Sheet material carrier
Inventor: SOGA TOMOKAZU
IPC: B65H3/08
Filed: 1990-12-14
Abstract: PURPOSE:To promptly carry out the feeding of a sheet material from a sheet means to a carrier means, and to smoothly carry out the passing operation of the sheet material to the carrier means. CONSTITUTION:When a photosensitive material 12 is drawn out by a sucker 14, a driving signal is supplied from a control circuit 20 to a pulse motor 18, and since the sucker 14 is oscillated from an angular position X to an angular position Y at a relatively high first angular velocity, the photosensitive material 12 is promptly carried. Since the sucker 14 is decelerated to a second angular velocity that is lower than the first angular velocity, and is thus oscillated to the side of a carrier means 16, the photosensitive material 12 held by the sucker 14 can be smoothly passed on to the carrier means 16.

Patent JP-S63502411-A (JP)
IPC: B01D33/04
Filed: 1987-03-31
Abstract: A dewatering method and apparatus is disclosed which uses a ramp at one end of a perforate conveyor in which the incline of the ramp may be adjusted while the dewatering operation is taking place. The ramp receives material to be further dewatered after the material has moved along the length of the perforate conveyor. The ramp causes the material to roll back upon itself as the material tends to move up the ramp, which rolling back action enhances dewatering. An actuator is coupled with said ramp for effecting movement of said ramp with respect to the conveyor to adjust the incline of the ramp with respect to the upper surface of the conveyor. In this way, the operator may readily optimize the rolling back action of the material to be dewatered to, in turn, thereby provide optimum dewatering. The ramp is also capable of being completely lifted out of the flow of material to be dewatered while the apparatus is in operation and while the dewatering process is being carried out.
