Patent JP-S63284885-A (JP)
Title: Circuit substrate
Inventor: MAEDA MASATOSHI
IPC: H01B5/14
Filed: 1987-05-15
Abstract: PURPOSE:To increase the sectional dimensional accuracy of a printed conductor and the mechanical strength of a substrate by changing the surface of the plastic insulating substrate into a roughened surface, bringing the roughened surface to a hydrophilic state through chemical treatment and forming the electroless plating layer and electroplating layer of a conductive metal onto the roughened surface turned into the hydrophilic state in succession. CONSTITUTION:The surface of a plastic insulating substrate 1 is roughened, a roughened surface 2 is brought to a hydrophilic state through chemical treatment, and the electroless plating layer 3 and electroplating layer 4 of a conductive metal are shaped onto the roughened surface changed into the hydrophilic state successively. That is since the dependency on a change into the roughened surface can be reduced by combining hydrophilic treatment, the irregular size of the roughened surface can be diminished, thus improving the sectional dimensional accuracy of a conductor for a printed circuit. Since the dependency on a change into the hydrophilic state by chemicals can be minimized only by the combination of the change into the roughened surface owing to the combination of the roughened surface, on the other hand the lowering of strength due to the deterioration of chemicals of the insulating substrate 1 can be alleviated, thus sufficiently ensuring the substrate strength of the printed circuit.

Patent JP-H08315306-A (JP)
Title: Storage
Inventor: MATSUMOTO AKIRA
IPC: G11B19/02
Filed: 1995-05-18
Abstract: PURPOSE: To suppress useless power consumption by supplying a control signal to a head circuit immediately before read-out operation. CONSTITUTION: Output waiting time of an MR head is shortened while suppressing power consumption by supplying a bias current to the MR head immediately before the read-out operation starts. That is, a counter circuit 78 in an MCU 64 counts a read reference clock RRCLK outputted from a read channel 71 after a write gate(WG) signal (RAW signal) outputted from a hard disk controller 56 started, and supplies the bias current to the MR head by making a RBAW signal a low level immediately before the write gate WG becomes the low level. Thus, the useless power consumption while write- operating is eliminated, and a WRR time is shortened.

Title: Manufacture of electrode for lead storage battery
Inventor: TAKAHASHI KATSUHIRO
IPC: H01M4/20
Filed: 1981-07-30
Abstract: PURPOSE:To obtain a shock-proof electrode by immersing an electrode body, which is prepared by making an active material in contact with an aqueous silicone emulsion, into a dispersion of resin particles which aren't bound to silicone. CONSTITUTION:An active material is made in contact with an aqueous silicone emulsion, and the mixture is subjected to drying process so as to obtain active particles. Thus obtained active particles are applied to a grid so that a porous electrode body coated with a porous elastic high-molecular silicone layer is formed. Next, the porous electrode body is immersed in a polytetrafluoroethylene dispersion or a polyethylene emulsion, and is dried so as to make an electrode for a lead storage battery. As a result, since the emulsion or the like hardly permeates inside the porous body coated with the active particles, and the deposited of the fluorine resin or polyethylene concentrates only around the surface of the electrode, a shock-proof electrode with a suppressed decrease of its characteristics can be obtained.

Abstract: PURPOSE: To enhance diffraction efficiency in at least two or more wavelength regions by forming both side parts of the diffraction grating surface to the triangular groove of the angle differring from that of other faces and letting the central part of the diffraction grating face be a rotating axis.  
     CONSTITUTION: The ray 5 incident to a certain state 1 of a diffraction grating is diffracted in the direction of 6 according to the optical rule of the diffraction grating. In the position 1 of the diffraction grating of a small incident angle, the ray is diffracted by the grating portion 3 (central region of the diffraction grating) but in the psoition 1' of a large angle of incident, it is diffracted even by the grating portions 2 on both side parts of the grating face. The diffraction efficiency of the grating portion 3 has the characteristics such as the curve 7 having blaze effect in short wavelength and the characteristics like the curve 8 having blaze effect on the long wavelength side and therefore if the center point 4 of the diffraction grating is inclined from 1 up to 1' with the central point 4 of the diffraction grating as a center, the diffraction efficiency may be enhanced in the wide wavelength region such as the curve 9 in which the curves 7 and 8 are combined.

Abstract: PURPOSE:To arrange a setting means at a position distant from a head, and to set a write current extending over many stages by separating the path of the write current to flow in an exciting coil and the path through which a setting current flows by a current miller circuit. CONSTITUTION:The current miller circuit 14 consisting of transistors Tr1 and Tr2 for separating the path of the write current Iwc to flow in the exciting coil 12 of the magnetic head 11 and the path through which the setting current Iref flows is connected to a selector switch 13. Since by changing a current from a reference power source Vref, i.e., the setting current Iref by setting optionally the combined resistance value (r) of each resistor 16 of a setting circuit 17, the quantity of the current to flow in the base of Tr1 is changed, the write current Iwc to flow in the exciting coil 12 can be changed indirectly. Thus, the setting circuit 17 can be arranged at the position distant from the head, and the write current can be set extending over many stages while evading the influence of current variation caused in a current path from the power source Vref.
