Abstract:
A head substrate for an ink jet head that discharges ink liquid retained in the ink retaining portion by the ink discharge mechanism in accordance with the printing data inputted from the outside into the data input portion comprises one base substrate having a specific position on the surface for the ink retaining portion to be arranged, and a fuse array storing various readably data freely by selective fusing. This head substrate further comprises a fuse logic circuit for controlling the operation of selective fusing of the fuse array and data reading. Then, the fuse array and the fuse logic circuit are arranged in a position in the direction orthogonal to the surface of the base substrate, but not overlapping with the ink retaining portion. With the fuse array and fuse logic circuit thus structured, this head can be made smaller and lighter in a better productivity as compared with a head for which a ROM chip should be installed separately. Also, it becomes possible to prevent any crack that may occur due to the local heat generated by fusing of the fuse array from being developed into the ink retaining portion for the reliable operation of the head.

Abstract:
A method of actively guiding and helping the user is disclosed, in which various supporting functions can be performed in accordance with a particular user situation. The method is equipped with user situation detection data having at least a user situation and a corresponding interaction pattern activated in such a user situation, supporting function select data having at least a user situation and a corresponding user supporting function name to be activated in the particular user situation, and at least one user supporting function. Each time an input is received from the user, the contents of the input are stored as an operation log data. The interaction pattern data of the user situation detection data is compared with the operation log data. If there is any coincident interaction pattern data, the supporting function select data is retrieved with the corresponding user situation data as a key, and the corresponding supporting function name is read, thereby activating the supporting function associated with the particular supporting function name.
Abstract:
The invention provides a solid polymer electrolyte having high performances in which the reaction area of electrode is increased by uniformly dispersing and bonding a solid polymer electrolyte and a catalyst and the ability of gas feeding to the reaction site is improved by adding a fluoropolymer so that the catalyst is not excessively coated. A method for making the fuel cell is also provided. The electrode provided on at least one side of a solid polymer electrolyte membrane is formed by coating on one side of a gas-diffusible layer a mixed dispersion of a noble metal catalyst, a carbon fine powder and a colloidal dispersion of a solid polymer electrolyte, the colloidal dispersion being prepared using an organic solvent having a polar group other than hydroxyl group in the molecule and having a carbon chain of 1-8 carbon atoms which bonds to the polar group or having a dielectric constant of 3-10.
Abstract:
In a thermal transfer recording sheet having a silicone layer on that surface of a plastic base film which is remote from a colorant layer, the silicone layer is formed by curing a radiation-curable silicone composition with electron beams or UV rays radiation. The composition is predominantly comprised of a (meth)acryloxy group-containing organopolysiloxane. The sheet is improved in heat resistance and lubricity and thus capable of forming clear images.

Abstract:
The present invention relates to a hot press to manufacture a substrate in which a printed circuit is provided.The hot press comprising at least one of vertically movable heating plates, a freely elevating movable platen which elevates the heating plates to press a plate to be treated between the heating plates, and a detecting means for detecting the movement of the uppermost heating plate when said uppermost heating plate starts to be elevated, in which the elevating speed of the movable platen is changed to a lower speed by a signal generated from the detecting device.This low speed control is carried out as follows. Relief valves and direction control valves are provided at a primary side and secondary side, respectively, of a clamping cylinder into which a ram for elevating the movable platen is inserted, and due to the difference of pressures between the primary and secondary sides of the clamping cylinder, it is made possible to successively change the clamping force from zero by elevating the ram at low speed, thereby giving a desired clamping force to the ram.
