Title: Magnetic recording and reproducing drum
Inventor: SAKAI KAZUO
IPC: G11B5/52
Filed: 1986-06-09
Abstract: PURPOSE:To improve the accuracy of swinging operation and to reduce the man-hours of the operation by working the outer peripheral surface of a rotary drum and magnetic-head fitting surface while the drum rotates. CONSTITUTION:A magnetic tape is wound spirally around the outer peripheral surface 12 of the rotary drum 1 which rotates freely on a fixed drum 2, and a magnetic head 5 mounted on the fitting surface 11 is projected slightly from the surface 12 to come into slide contact. While the drums 1 and 2 are coupled, the surface 11 is worked to maintain the perpendicularity between a shaft 3 and the surface 11, and the outer periphery of the surface 12 is worked to eliminate the vibration of the outer periphery. Thus, the working is carried out in the rotating state of the drum 1 to eliminate the need to make adjustments for the improvement of the accuracy of swinging and also reduce the man-hours of the operation, thereby improving product accuracy.
Patent JP-H01302660-A (JP)
Title: Sealed type lead-acid battery
Inventor: INOUE TOSHIHIRO
IPC: H01M4/62
Filed: 1988-05-30
Abstract: PURPOSE:To enhance the rate of utilization and prolong the cycle lifetime of charging/discharging by changing the active substance density (porosity) across the thickness of the electrode plate, and making in multi-layer construction. CONSTITUTION:A double construction is incorporated by laying positive electrode active substance in layers in the thickness direction of the electrode plate from its center toward outside with a lower density (higher porosity) layer 2 situated in the central part of the electrode and with a higher density (lower porosity) layer 3 situated in the part contacting separator of the electrode plate surface. Accordingly, even repetitive charging and discharging does not cause the active substance to be turned into fine particles at the layer in the electrode plate surface part. Also the central part of the electrode plate has high porosity, which facilitates dispersion of the electrolyte and enriches existence of the electrolyte. This enhances the rate of utilization of the active substance and accomplishes a battery with large capacity and an excellent cycle lifetime of charging and discharging.

Abstract: PURPOSE:To eliminate the need for a large capacity memory by overlapping optically a sensible picture stored on a transparent film and a belt form photosensitive body, reading and converting it into picture information coded electrically. CONSTITUTION:The picture information described on the transparent film 27 is converted into an analog signal by a CCD34, converted into a digital signal by a binary coding circuit 41, outputted from an interface circuit 43 to a bus line 44, fed to an optical disc device 46 and recorded on an optical disc. Further, the picture information recorded on the optical disc is read by an optical disc device 46, fetched in a picture display device 40 via the bus line 44 and inputted to a laser drive circuit 42 and formed on the belt form photosensitive body 8 as a sensible picture. Thus, the picture on the belt form photosensitive body 8 and the transparent film 27 is synthesized optically and the synthesized picture information read by a CCD34 is recorded separately from the other picture.

Abstract: PURPOSE:To edit and create technical data and documents having plural types of table formats in the respective table formats from the same editing data by separately storing the editing data, data formats, and table formats to compose data having the table formats and editing the data having the table formats by combining them. CONSTITUTION:The editing data, the data formats, and the table formats to compose the data having the table formats (such as the technical data and the documents) are separately stored in respective storing parts 34, 36, and 38, and the data having the table format are edited by combining them in a table editing part 39. Thus, it becomes possible to edit not only a cutform but also the technical data and the documents having the plural types of different table formats from the same editing data by defining the table formats, and it also becomes possible to edit and create different editing data in the respective table formats without defining their table formats again. Consequently, it becomes unnecessary for a table implementor to input the same editing data many times according to the formats of the tables.

Filed: 1991-06-04
Abstract: PURPOSE:To establish the cell synchronization by resetting a consecutive residue calculation circuit to the initial state when residues of residue calculation circuits each calculating a residue continuously differ. CONSTITUTION:When CRC(Cyclic Redundancy Check) is implemented, a timing circuit 112 is reset and phase conversion is implemented based on a byte phase of the CRC detected by a pattern detection circuit 111 this time. When the detected CRC pattern is correct. Thus, when the detected CRC pattern is correct, a data with a correct byte phase is outputted as an output of a phase converter 102. Arithmetic operation circuits 108,105 to obtain the CRC have the same function. Furthermore, a memory 109 is initialized for each of 6 bytes while cell synchronization is not established and then initialized for each 53-byte after the synchronization is established. In this case, the CRC of the 1st CRC arithmetic operation circuit 10 and the CRC of the 2nd arithmetic operation circuit 11 are compared and when the result of the arithmetic operation differs, the 1st CRC arithmetic operation circuit 10 being a continuous arithmetic operation circuit is reset.

Abstract: PURPOSE:To equip a diode with reduced junction capacity and a voltage withstanding capability suitable for a protecting element by a method wherein a highly doped region of the one conductivity type bridges a highly doped isolating region and an anode region which are formed on a semiconductor substrate of the opposite conductivity type. CONSTITUTION:A substrate 2 and epitaxial layer 3 are low in impurity concentration and form a P-N junction consisting of two low-concentration layers. A P<+> type impurity is diffused deep into an isolating region 4 and anode region 6. With the P-N junction with the epitaxial layer 3 being composed of two low- concentration layers, a low junction capacity realizes. When an N<+> type doped region 7 is formed, to bridge the high-concentration regions belonging respectively to the isolating region 4 and anode region 6, on the surface of the epitaxial layer 3 positioned between the isolating region 4 and anode region 6, high- concentration P-N junctions are created between the anode region 6 and doped region 7 and between the doped region 7 and the isolating region 4, providing the protecting diode with a required voltage-withstanding feature.

Title: Basket for electrode
Inventor: MUTO TSUNEFUMI
IPC: C25D17/12
Filed: 1988-06-01
Abstract: PURPOSE:To prevent the bridging phenomenon of a soluble anode packed in a basket by making the cross-section of the lower part of the basket larger than that of the upper part. CONSTITUTION:The cross-section of the lower part of a cylindrical basket for packing a soluble anode for electroplating is made larger than that of the upper part. The soluble anode packed in the basket is dissolved by electrolysis and lowers slowly. Since the side of the basket slopes outward, the anode is not caught by the side of the basket and the bridging phenomenon of the anode is prevented, so the basket is effective in preventing the anode from becoming hollow.

Abstract: PURPOSE:To enable an ink even containing many bubbles to be positively recovered, by arranging an enlarged portion to the lower end of a recovering pipe that is connected with an ink recovering gutter, the enlarged portion being positioned in a sub-tank capable of vertically moving in an ink tank so that the pressure in the recovering pipe may become negative. CONSTITUTION:When tha ink is recovered, an electric current is passed through an electromagnet 22, and thereby the sub-tank 21 is lowered to cause the liquid surface A therein to be lowered, so that an exhaust valve 20 is closed to permit the pressure within the enlarged portion 19 to be negative and owing to this negative pressure the ink collected in the gutter 7 is smoothly recovered via the recovering pipe 8. When an electric current is applied to the electromagnet 22 such that the polarity thereof is reverse to the above case, the repulsion force pushes up the sub- tank 21 to cause the liquid surface A to be raised and therefore tha air within the enlarged portion 19 is released through the exhaust valve 19 so that a next negative pressure creation stage will be ready.
