IPC: G11B27/36
Filed: 1994-06-09
Abstract: PURPOSE: To make it possible to easily detect formatted blocks and decide their validity by coping with a format entity pattern by using a programmable corresponding threshold value in each required mode. CONSTITUTION: In a read-only (R) mode and a read-while-write(RWW) mode, PLL 40 of a block/validity detection system 36 detects a synchronous character, and at the same time, a burst detection logic circuit 42 detects an interblock gap (IBG), a synchronous burst, by using a threshold value of a parameter/ threshold circuit 48. These detection patterns are decided as valid for threshold values higher than the detected ones from the circuit 48 by the individual logic circuits 64-66 of synchronization, IBG, and burst qualification, and when the validity are not satisfied, a status message requesting for Θ-block rewrite is generated, and it is possible to easily detect blocks and decide their validity.

Filed: 1979-10-05
Abstract: PURPOSE:To realize an address setting for a memory device without increasing the number of pins of the memory module, by connecting in series several units of equally constituted memory modules in which the A/D converter and the diode are added. CONSTITUTION:The memory modules M1-M8 possess an input terminal and an output terminal each for setting of address, and each adjacent module is connected one another via the lines L1-L8 and in series.

Title: Sliding contact material
Inventor: FUJISHIMA SUSUMU
IPC: H01R39/20
Filed: 1984-06-21
Abstract: PURPOSE:To obtain a sliding contact material having low and stable contact resistance by adding prescribed amounts of Cu, Cd and one or more among Al, Ga and Mn to Ag so as to control the stickiness of an Ag-Cd alloy and to improve the wear resistance. CONSTITUTION:A sliding contact material is obtd. by adding 3-12wt% Cu, 0.5-5wt% Cd and 0.5-10wt% one or more among Al, Ga and Mn to Ag. When 0.01-0.5wt% Fe group element such as Fe, Ni or Co is substituted for part of said added elements, the grains can be made fine and the wear resistance is further improved. Since the sliding contact material hardly softens and has superior wear resistance, when the contact chips of a commutator for a small-sized motor are made of the sliding contact material, the contact chips produce very little dust due to wear during sliding along brush contacts. No noise is generated and a beneficial effect such as low and stable contact resistance is shown.

Abstract: PURPOSE:To suppress water from concentrating in a local abnormal electric field part so as to prevent generation of water trees by forming an insulator with a hydrophilic polymer, having an acidic radical in a molecule, or with a blend polymer in which the hydrophilic polymer is blended. CONSTITUTION:A tube of three-layer structure with a 2mm thick electric field relaxation layer, 5mm thick main insulation layer and a 1mm thick external semiconductive layer is formed by simultaneously extruding the three layers, pressure-heated and cross-linked. In the main insulation layer, a composition, which contains 2 pts.wt. Dicumyl Peroxide peroxide as a cross linking agent and 0.2 pts.wt. 4,4'-Thio bis as an age resistor, is used. Nitrogen gas is pressure- injected in an internal surface of the tube of three-layer structure, and by spreading the tube to 1.5 times the diameter at a temperature of 160 deg.C while cooling the tube to a room temperature, a thermal shrink tube is obtained. Thus by substantially reducing generation of water trees in an insulator, insulating performance can be prevented from deteriorating due to an voltage application.

Abstract: PURPOSE:To obtain the title antenna suitable for a broad band reception antenna by providing a main antenna extending from its side to its upper side, up to nearly its full side along the circumferential of a window pane while using one lower side of the window pane as a feeding pint and an impedance adjusting antenna to one side of the window pane of the main antenna. CONSTITUTION:The main antenna 2 and the impedance adjusting antenna 3 are printed and baked together with the feeding pint 4 on an in-cabin side plate glass 1 by using a conductive paste. In case of receiving a TV broadcast wave or an FM radio broadcast wave, the antenna extending from the lower end of one side till at least the upper side, nearly the full side along the circumference of the window pane acts like the main antenna 2 over the entire frequency. The deterioration in the reception gain due to partial mismatching loss in case of mismatching is reduced by approximating the antenna impedance of the impedance adjustment antenna 3 to the impedance of a feeder (coaxial cable). Thus, the broad band reception is attained.
