Abstract: PROBLEM TO BE SOLVED: To provide a magnetic recording medium prevented from the generation of cupping and exhibiting high running stability by forming a back coat layer having a column structure, formed by controlling the structure to non- obliquely vapor deposit, on the surface opposite to a magnetic layer on a non- magnetic supporting body. SOLUTION: In the non-magnetic supporting body constituted so as to film- form a single layer of a metal cobalt magnetic layer with a prescribed thickness by obliquely vapor depositing on a PET film and to film-form a protective layer with a prescribed thickness thereon, the back coat layer is formed on the surface opposite to the magnetic layer of the non-magnetic supporting body. In such a case, gaseous oxygen is introduced under a prescribed condition at the time of film-forming the back coat layer on the non-magnetic supporting body on a cooling can roll. Further a fluorine based lubricant is applied as a lubricant layer with a prescribed thickness on both surfaces of the protective layer of the magnetic layer and the back coat layer. As a result, the back coat layer is formed from a thin film having a random structure.

The liquid mixture is passed through the 1st oxygen electrode 11, a column 10 is a prescribed length and the 2nd oxygen electrode 12. The first quantity of the dissolved oxygen in the liquid mixture is measured with the electrode 11 and the quantity of the dissolved oxygen after the lapse of prescribed time is measured with the electrode 12. The quantity of the dissolved oxygen decreases during the passage through the column 10. The pass time is about 0.5-4.5min and the concn. of the activated sludge is determined from the decreasing rate of the quantity of the dissolved oxygen. The quick and accurate measurement of the concn. of the activated sludge and the dissolved org. material is thus made possible as the decreasing rate of the quantity of the dissolved oxygen is measured.

Title: Cpu device
Inventor: OKAMURA NAOYA
IPC: G06F12/16
Filed: 1989-09-28
Abstract: PURPOSE:To prevent the destruction of a content in RAM by approving access to RAM only when CPU executes the processing of a prescribed program stored in ROM. CONSTITUTION:ROM 3, ROM 4 and an I/O interface 6 are connected to CPU 1 through a data bus and an address bus. A chip selector 2 is connected to CPU 1, and the selection signal of the chip selector 2 is directly inputted to ROM 3 and to RAM 4 through an OR gate 5. ROM 3 and ROM 4 can be accessed only when a port connected to the chip selector 2 becomes 'Low' and it can access to RAM 4 only when CPU 1 executes the processing of the program stored in ROM 3. Consequently, CPU cannot access to RAM 4 in a state where ROM 3 is not connected to CPU 1. Thus, the destruction of the backup data stored in RAM is prevented.

Abstract: PURPOSE:To obtain a rubber sheet wherein staple fibers are highly oriented in the thickness direction thereof by a method wherein a preheated rubber sheet material is pushed in a rubber passage while folded up and push-in pressure is formed to apply adhesion to the rubber sheet. CONSTITUTION:At first, staple fiber mixed rubber is rolled by a calender to prepare a rubber sheet material S which is, in turn, preheated by preheaters 5A, 5B to be pushed in a rubber passage 2 while alternately folded up by push-in plates 4A, 4B. At this time, the rubber sheet material S pushed in the rubber passage 2 between molds 1A, 1B in a folded state is heated. The rubber sheet material S thus pushed in the rubber passage 2 is moved in the left direction by the rubber sheet material S successively pushed in from the back while folded up and restricted over the distance corresponding to the length of the molds 1A, 1B by the molds 1A, 1B to be discharged as a thick rubber sheet 2 from the molds 1A, 1B. The slide friction force of the rubber sheet material S during this period becomes pressing force at the time of pushing-in and sufficient adhesion is obtained.

Abstract: PURPOSE:To perform sealing excellent in airtightness even when positional slippage between separator glass and a metal foil is generated by making width of the metal foil laid on the flat surface of a separator glass smaller than width of the flat surface of the separator glass. CONSTITUTION:A quartz glass container 1, in which xenon gas is sealed, consists of the main body 2 in the oval-spherical shape and the sealing parts 3 and 4 extending to its both sides. A tungsten-made cathode 5 having a diameter of about 2mm and a tungsten-made anode 6 having a larger diameter of about 5mm than this, whose respective base end parts are sealed to the sealing parts 3 and 4, are connected to the outer leading-in bodies 11 and 12 through the molybdenum-made metal foils 9 and 10 for air-tight sealing laid on the surfaces of the separator glass 7 and 8. Here, by making width l of the metal foil laid on the flat part of the separator glass smaller than width L of the flat surface of the separator glass, lowering of air-tightness is checked in spite of possible positional slippage between the separator glass and the metal foil.

Title: High-speed blind equalizing method for adaptive equalizer
Inventor: BAHABUESHIYU BAHARUKANDORA BAH
IPC: H03H21/00
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To improve processing time without deteriorating the quality of an equalization processing by starting a decision directed adaptive equalization processing when coefficients are converged at the blind equalization for the sub-set of the coefficients in an adaptive equalizer. SOLUTION: When a new signal is detected in a detector 10 (when power is supplied), a micro processor in a coefficient control network 80 executes a blind equalization processing. Namely, all the coefficients of a 128 tap FIR filter in the adaptive equalizer 20 are preset, and they are set to be zero except for eight intermediate taps. Then, 32 intermediate taps are tried to be blind- equalized and whether the coefficients of the adaptive equalizer 20 are converged or not is judged. When they are converged, the decision directed adaptive equalization processing is started. When the coefficients are not converged, blind equalization is repetitively executed by using the larger sub-set of the coefficients. When such blind equalization processing process is used, speed can be improved by 4:1, namely, speed can be improved by four times.
