Title: Method for driving bubble jet printer head
Inventor: SUZUKI KATSUMI
IPC: B41J2/05
Filed: 1987-05-29
Abstract: PURPOSE:To enhance a head in durability with low cost without complicating the head in structure, e.g. forming a protective layer, by a method wherein a required energy is applied to a heating resistor to make an electric potential pulse uncontributing to generate bubbles exist with the electric current direction reverse to that of a bubble generating drive electric potential pulse. CONSTITUTION:An electric potential V1 of a common electrode 1 is always constant. On the other hand, an electric potential V3 of a select electrode 3 pulsatively varies when the heat generation of a heating resistor 2 is required. After bubbles are generated by applying an energy required for generating bubbles of required size by a drive electric potential pulse, a sub-pulse uncontributing to generate bubbles is again applied to the select electrode 3. From a relation of V3>V1>V2 where an electric potential of the sub-pulse is V2, the electric currents of the drive electric potential pulse and the sub-pulse flow reverse to each other. In this manner, since the electrodes are exchanged between anode and cathode, the eluation amount apparently becomes 0 with the same ratio of anode and cathode alternatively by the reduction in electrode eluation amount by a ratio simply failing to turn to anode or by the redeposition of metal ions in an electrode material, which was eluted in an anode process, on the electrodes in a cathode process.

IPC: G06K19/073
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To provide a portable data carrier whose issuance processing is simplified, without increasing the program capacity. SOLUTION: When a signal RST is supplied from the outside to initialize an IC card before a series of operations, a CPU 1 which executes a program stored in a ROM 2 sets all flags on a RAM 3 to 'collated state' and retrieves each reference key from an EEPROM 4.

In issuance processing which follows, a route directory is generated in the final access condition, and an MF(master file) is generated, and plural reference key files, including individual reference key data, are successively generated. Since the final access condition is set to the MF, it is unnecessary to rewrite the pertinent access condition.

Title: Hydraulic steering unit
Inventor: SAGAWA RYUICHI
IPC: B63H25/24
Filed: 1986-06-10
Abstract: PURPOSE:To enhance the accuracy of steering angles, by computing a variation in angle for starting the neutral position recovery operation of a solenoid control valve in accordance with a detected steering angle, and by computing the angle for starting the neutral position recovery operation with the use of a subtracting means so that a neutral position recovery signal is produced in accordance with the output value of the subtracting means. CONSTITUTION:An angular difference computing means 8 computes a difference be tween a steering angle thetaa from a steering angle detecting means 7 and an instruction steering angle thetac. Further, a variation amount computing means 9 receives the steering angle thetaa and computes a variation angle theta1 for changing the angle for starting the neutral position recovery operation of a solenoid control valve 1. Further, a subtracting means 15 computes a difference between an output value from the computing means 8 and an output value from the computing means 9. When a valve drive control means 16 detects the above-mentioned difference which falls into an allowable range alpha1, a neutral position recovery signal for the solenoid control valve is produced. According ly, the neutral position recovery operation of the solenoid control valve is initiated before the value of ¦thetac-thetaa¦ becomes alpha1, and therefore, the steering angle may fall in an instruction angle range thetac+ or -alpha1 even through the allowable range alpha1 is small.
