Title: Magnetic disk controller
Inventor: OKADA NAOYUKI
IPC: G06F3/06
Filed: 1982-09-03
Abstract: PURPOSE:To prevent data destruction, by giving a priority level to access for input and output to and from a magnetic disk and allowing only access given a higher priority level than that recorded on the disk. CONSTITUTION:The input/output bus of an interface control part I/F2 is connected to a buffer memory 4 to store data therein temporarily. An input to the magnetic disk is sent from the memory 4 to a head 12 through an amplifier 5 and an AND10 and an output from the magnetic disk is sent from the head 12 to a priority level recognition part 6 through an AND11, amplifier 9, and discrimination signal discriminator 8. The output of the I/F2 is sent to an I/O control part 3 and a priority level comparing part 7. The output of an I/O3 and the output of the comparing part 7 are sent to the ANDs 10 and 11. The output of the comparing part 7 is fed back to the I/F2. The comparing part 7 compares the input from the I/F2 with the input from the priority level recognition part 6 and turns on the AND10 only when the the input from the I/F2 has priority. Consequently, data is prevented from being destroyed.

Abstract: PURPOSE:To control an output signal frequency in a wide range with control voltage less in the remaining reference frequency component, by providing a means superimposing mother DC voltage on a DC voltage obtained through smoothing an output signal of a phase comparator. CONSTITUTION:An output of a programmable divider 2 and an output of reference frequency generator 4 are compared with each other at a phase comparator 3, and this comparison output signal is inputted to a low-pass filter 5. Another DC voltage is superimposed on a DC voltage obtained from smoothing with an LPF5 by a DC bias circuit 7 to obtain a control signal of a voltage-controlled oscillator 1. In a bias circuit 7, a plurality of variable resistors VR1-VR3 are connected in parallel with a DC power supply E, and a slider of each variable resistor is selectively connected to the voltage-controlled oscillator 1 via a switch SW, and a control voltage can be obtained by interlocking the switch SW with a program switching operation to the programmable divider 2.

Title: Manufacture of thin film red el element
Inventor: TSURUMAKI NAOYA
IPC: H05B33/10
Filed: 1989-06-15
Abstract: PURPOSE:To obtain a high luminance and high stability thin film red EL element by depositing three evaporation materials of Zn, S, and MnF2, while controlling them independently in a vacuum evaporation apparatus. CONSTITUTION:Three evaporation materials 2-4 of Zn, S, and MnF2, are vacuum-deposited in a vacuum evaporation apparatus 1, while being controlled independently. This provides decrease in defects of the material of ZnS and an ease in attaining an optimum MnF2 density. The emission layer 12 gains high stability and provides a high-luminance emission with an emission center at Mn-F. The color of the Mn-F-centered emission has a longer wave length than the color of the Mn-centered emission, and gives a high-luminance colored emission when coupled with a red color filter thanks to an increase in the rate of transmission through the filter. Thus, a thin film red EL element with a high stability and a high luminance is obtained.

Abstract: PURPOSE:To perform transmission and reception in a lens composition surface with less reflection and high efficiency and obtain an image of high quality by sticking an organic high polymer film on the surface of an acoustic lens composition surface part. CONSTITUTION:The recessed surface of an acoustic lens 3 is coated with the high polymer film 11, which uses a vapor-deposited film of polyparaxylene preferably. Then, a film of 0.2mum in thickness is vapor-deposited under a vacuum uniformly without any pinhole and its thickness is controlled optionally. The acoustic impedance of this material is - 3X10<5>g/cm<2>.sec and this value is almost an intermediate value between the acoustic impedance of crystal forming the acoustic lens 3 and the acoustic impedance of a sound wave propagation medium, so this material 11 is formed to a thickness equal to lambda/4 (lambda: wavelength of sound wave), thus obtaining a sufficient matching layer.

Title: Electroencephalograph
Inventor: YASUSHI MITSUO
IPC: A61B5/0476
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To quickly induce a target brain wave without any necessity of a preliminary learning by providing a phase compensation means which arranges a phase of each wave so as to coincide the timing of changes in the optical intensity of an electroencephalographic optical signal with the minimum and the maximum positions of amplitude changes in induced α, θ, and β waves. SOLUTION: A band filter 4 passes only signal components corresponding to a target brain wave out of brain wave signals and corresponds them to α, θ, and β waves, their central frequency is set within the bands of respective waves, and Q value is so set that the passing band width becomes narrower than the respective band areas. When a user receives optical stimulus by blinking light, its drawing effect, for example, strongly induces the α waves in the brain waves, a closed loop connecting and circulating the device and the user is formed, and a kind of oscillating circuit setting the αwave component signal to a starting frequency is constituted.  A phase is so set that the blinking timing of the stimulus light emitted by an optical wave stimulus device 5 is coincided with the maximum and the minimum positions of the amplitude changes in the α wave so that it more efficiently induces the target brain wave.

Title: Double superheterodyne receiver
Inventor: KUDO YASUHARU
IPC: H04B1/26
Filed: 1986-06-30
Abstract: PURPOSE:To obtain stable reception performance by dividing a single frequency signal outputted from one oscillator into two, multiplying or frequency-dividing the one and giving the result to one frequency converter and giving the other directly to the other frequency converter, thereby using one local oscillator enough to stabilize the oscillation frequency of one oscillator. CONSTITUTION:A single frequency of 51.925MHz outputted from an oscillator 13 is divided into two, the one is subject to 5 multiple by a multiplier 14 to be converted into a frequency of 259.625MHz, which is supplied to a 1st frequency converter 3 as the 1st local oscillation signal via a buffer 5. Then the other is supplied to a 2nd frequency converter 7 via a buffer 9 as a 2nd local oscillation signal without frequency change. As a result, the accuracy of the single frequency signal outputted from the oscillator 13 is easily stabilized. Since the frequency deviation in the 1st and 2nd local oscillation signals is suppressed within a range in the increasing or decreasing direction only, the reception performance of a double superheterodyne receiver is stabilized easily.

Then the surface is sputtered and flattened by chemical mechanical polishing, and an inductive head is formed thereon. Thus, the ion milling process to remove the oxide layer on the lead second layer is performed after a seed first film is formed.

Abstract: PURPOSE:To enable checking work without detaching whole device by forming an annular frame in a detachable double frames inside and outside. CONSTITUTION:An outer annular frame 23 holding a water seal plug 18 pressed to a main steam nozzle 2 from the inside of a reactor pressure vessel 1 and an inner annular frame 24 for pressure retention are formed in detachable double concentric frames. In regular checking, the plug 18 is placed to the nozzle 2 at the first stage and so the inside diameter phiD of the frame 23 is approximately the same as the inside diameter phid of the reactor water supply pipe 22 or larger than the core 7 so as not to disturb the later fuel motion. Therefore, the frame 23 can be made thin and can not bear the test pressure exerted on the nozzle 2 side during a leak test of the pipe system. Therefore, the frame 24 is placed inside the frame 23 before the test and the bending distortion due to the test pressure is suppressed. After completing the test, the frame 24 is taken off and all the works in the vessel 1 are possible to the carried out in a wide space as leaving the plug 18 at the position fitted.
