Title: Electronic disk subsystem
Inventor: OKADA MITSUO
IPC: G06F3/06
Filed: 1991-06-04
Abstract: PURPOSE:To shorten the saving operation time by saving only tracks which cannot be saved by the successive saving operation during a system operation at the time of the save operation at the time of power trouble or shutting off the system. CONSTITUTION:A control part 1 receives the instruction from a high-order device to control a data storage part 2. When a write instruction is executed, the write address of the data storage part 2 is stored in a control memory 3. During the system operation, a wave timing determining circuit 5 sends the timing for which a timing generating circuit is generated at the intervals of a fixed time, to a save control circuit 4 and decodes the control memory 3 at this timing and saves the updated part of the data storage part 2 in a save magnetic disk device 8. When the saving operation is performed at the time of power trouble or the shutting-off the system, a saving command detecting circuit 7 detects this state to report it to the save timing generating circuit 6, and the continuous timing is sent to the save control circuit 4, and the control memory 3 is decoded to perform the saving operation.

Abstract: PURPOSE: To provide a stabilized particled condition constantly by a method wherein a means for detecting the charging characteristics of the charged ink droplets is provided, and the amplitude of the excitation signal is controlled on the basis of the signals from the detecting means.  
     CONSTITUTION: The detection circuit has a capacitor 13 provided between the ink and the ground. When a pulse-shaped charging voltage is impressd on the charging electrode 6, and if an droplet is separated from the ink jet stream, a charge being equal inquantity but opposite in polarity to that on the ink droplet is stored in the capacitor 13. When n sampling pulses each corresponding to 1/n of the period of a reference frequency are utilized as the pulse-shaped charging voltages and the pulse voltages Vj(n) are continuously fed for m excitation periods so as to provide each respective driving action, the charges equal in quantity to those given to the ink droplets are sequentially accumulated in the capacitor 13, obtaining output waveforms (a), (b), (c). In the case of the waveforms (a) and (c), printing is impossible. In the case of the waveform (b), the amplitude of the excitation signal is augmented by an amplitude control circuit.

Abstract: PURPOSE:To omit the positioning of leads with an electrode pattern surface and an electrode pattern by superposing and forming a mesh on the part parallel to the mesh which is contacted directly with the surface of the electrode for a light receiving surface. CONSTITUTION:Electrodes 31 are formed on the light receiving surface 301 of a solar battery base 30, and hexagonal mesh part 312 is superposed on the hexagonal mesh part 311 which is contacted directly with the surface 301. The part 312 is used also as leads, the size of the mesh of the part 311 is decreased in size than the part 312 to enhance the current collecting efficiency. According to this structure, since the part 312 is not directive in the mesh, it is not necessary to position the part 311 with the part 312 (current collecting electrode, leads), the connecting points are distributed uniformly on the overall light receiving surface, thereby improving the photoelectric conversion efficiency and the reliability of the connection. The hexagonal mesh has larger degree of freedom of rotation as compared with a square or triangular mesh so that the branches from the nod are only three, thereby enhancing the current collecting efficiency with high flexibility and facilitating the connecting work.

This layer 2a is quenched by dipping into liquid nitrogen, and when ultrasonic waves are projected thereon, cracks are generated in lengthwise and breadthwise directions on a resist film 2 including the degenerated and hardened layer 2. Then, when an ashing operation is conducted, the inner part of the film 2, leaving the film 2, is vaporized quickly, and at the same time, the greater part of the layer 2 is slipped off. Then, when dustfree air or nitrogen compressed gas is made to flow on the surface of the substrate 1 using an air gun and the like, the remaining layer 2 can be removed.
