IPC: H05K7/20
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To efficiently cool a heater element even if there is an obstacle around the heater element by diffusing heat generated from the heater element by fins and controlling the direction of air in cooperation with a fan. SOLUTION: This device comprises a heater element 1, a fixed stand 2 fixed on the heater element 1, a rotary stand 3 provided on the fixed stand 2, a heat sink 4 in which fins 41 are vertically provided on the rotary stand 3, and a fan 5 attached perpendicularly to the heat sink 4. Consequently, even if there is an obstacle 6, since air 7 sucked by the fan 5 and heat 8 discharged from the fan 5 are in the opposite positions, the air 7 and the heat 8 are not mixed, so that the heater element 1 can be sufficiently cooled. The direction of the fan 5 can be adjusted by the rotary stand 3 to a gap between the obstacles 6 and each of the fins 41 serves as a passage of hot air, so that strong directivity is added to the direction of air and the heat 8 can be certainly discharged to the outside.

Title: Power output device
Inventor: URANO HIROAKI
IPC: B60L50/16
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide a power output device of consuming electric energy in a battery means and preventing an overcharge in the battery means without having an influence on an output of power to a driving shaft, along with no increase in the number of parts. SOLUTION: When a remaining capacity of a battery 94 is over a given set value near to a full-charge state, one motor not operated is selected out of a clutch motor 30 or an assist motor 40 on the basis of a connection states of a first clutch 45 and a second clutch 46. Then, only a d-axis current (field current) is fed to three-phase coils of the motor not operated. Then, the electric energy in the battery 94 is consumed as a copper loss in the motor. Since a q-axis current (torque current) is not carried in the three-phase coils in the motor, the torque is not developed in a driving shaft 22 or a crank shaft 56, and thereby there are no influence on an output of power to the driving shaft 22.

Title: Dicing device
Inventor: KITO KENICHIRO
IPC: B24B41/06
Filed: 1992-11-04
Abstract: PURPOSE:To prevent a dicing device from causing the clogging of a suction groove by dust, chips, etc., by providing an opening for suction at the topside of a dicing table, and sucking and holding a pallet on the topside, and sticking a wafer onto the pallet through a double-sided adhesive tape. CONSTITUTION:A pallet 10, whereon a wafer 30 is stuck through a double-sided adhesive sheet 20, is placed on a dicing table 1, and the pallet 10 is heated after cutting the wafer 30, using a diamond blade 40. Though the adhesive strength of the first binder layer 22 of the adhesive sheet 20 drops by heating, the adhesive strength of the second binder layer 23 does not drop. Since the adhesive sheet 20 sticks fast fast to the pallet 10 by the binder layer 23, a chip can be taken out easily of the adhesive sheet 20. The dust, chips, etc., adhering to the pallet 10 fall onto the dicing table 1, and one part of them may get in a suction groove 2, but the suction groove 2 has an opening area, so it cannot cause clogging.
