Title: Battery cooling device
Inventor: KATSUTA TOSHIHIRO
IPC: H01M10/613
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To correctly perform determination whether a battery is fully charged or not even if control for changing the gas volume of a cooling fan from high to low is performed. SOLUTION: In a step S5, when the voltage of a battery exceeds a set voltage A close to that of the full charged battery, it is the case that the charged state of the battery approaches full charging, and process proceeds to a step S6, to carry out a fan mode changeover prohibiting process so as not to change the gas volume. Since the gas volume is not changed when the battery is in a charged state close to the full charging, determination can accurately be performed without being affected by the change of the gas volume in the determination based on the temperature whether the battery is fully charged or not.

Filed: 1990-02-07
Abstract: PURPOSE:To confine any charge particles contained in discharged plasma in a magnetic field for effectively avoiding the arrival of the charged particles at a wafer thereby enabling the plasma gas in high density to be produced for accelerating the processing rate by installing a local magnetic field impression means between a plasma producer and a processing chamber. CONSTITUTION:Any discharged plasma 3 is confined in a magnetic field generated by a magnetic field impression mechanism 9 installed on the peripheral part of a discharge tube 4. Accordingly, especially the charged particles such as ions, etc., contained in the discharged plasma 3 are effectively confined in the magnetic field so that specified particles such as radicals or neutral particles, etc., may selectively reach a wafer 6 to be processed. In such a constitution, it is recommended that said magnetic field impression mechanism 9 is installed as close as possible to the plasma producer, that is, as high as possible from the discharge tube 4 so that the effect of confining the plasma gas is enhanced thus enabling the plasma gas in high density to be produced.

Title: Ink jet head
Inventor: TAKAHASHI MASAHIRO
IPC: B41J2/16
Filed: 1988-02-09
Abstract: PURPOSE:To prevent the bending vibration of the whole of a nozzle plate in the thickness direction and to enhance jet energy efficiency, by providing grooves not only to the front surface of an elastic plate but also to the back surface thereof at the positions corresponding to ink pressure chambers in a direction facilitating the deformation of the elastic plate. CONSTITUTION:An elastic plate 2 is placed on a nozzle plate 4 to which the nozzles communicating with ink pressure chambers 1 are formed by half etching and piezoelectric elements 3 are bonded to the elastic plate 2 at the positions corresponding to the ink pressure chamber 1. A large number of grooves 5 are carved in the elastic plate 2 in parallel to the longitudinal direction of the piezoelectric elements 3 by half etching. Since the elastic plate 2 is easily bent when an electric pulse is applied to the piezoelectric elements 3, an ink jet head can be driven at low voltage and jet energy efficiency can be improved. Further, since the bending of the elastic plate 2 is locally excited corresponding to each of the piezoelectric elements 3 and each of the ink pressure chambers 1, the interference with adjacent nozzles can be suppressed.
