Title: Fluorescent screen of color picture tube
Inventor: INOUE TAKUJI
IPC: H01J29/20
Filed: 1977-09-30
Abstract: PURPOSE: To increase the contrast on the fluorescent screen of the color picture tube by coating the fluorescent powder of average diameters 8W14μm with under 5wt% of particle in less than 5μm diameter and under 0.5 wt% of particle in less than 3μm diameter.  
     CONSTITUTION: The color fluorescent screen produced in such particle distribution contains no fluorescent powder of the minute particle especially at the side where the powder layer touches panel 1p. Therefore, the light dispersion due to the minute particle can be avoided, and furthermore the reflection light enters between powder particles of comparatively large diameters to produce the maze effect. Thus, no reflection light reaches the dark part easily. In this way, the lowering of the luminance at the dark part, that is, the lowering of the black level to decide the contrast becomes possible, thus increasing the contrast and thus enhancing the picture quality

Title: Data base management system and retrieval method therein
Inventor: HATANAKA KATSUMI
IPC: G06F17/30
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To evade such a state that it takes a too long time to smoothly advance subsequent processes when retrieval is a data base is processed and as a result, the response of the whole processes becomes worse. SOLUTION: A retrieval part 2 generates retrieval result data once having retrieved one record from the data base. The retrieval result data has the retrieved record set as head information and information, indicating whether or not there is an unretrieved record, set as tail information. Then, a processing part 5 performs a process based upon a program for the record in the retrieval result data and sends the retrieval result data back to the retrieval part 2 while passing the result of the process to an output part 8. The retrieval part 2 judges whether or not retrieval should be done again from the tail information in the retrieval result data.

Title: Power line carrier control system
Inventor: HARA TAKASHI
IPC: H04B3/54
Filed: 1989-05-12
Abstract: PURPOSE:To prevent generation of high frequency noise by providing a control means generating a carrier original signal only at the time of transmitting a carrier transmission signal. CONSTITUTION:When power is applied, a clock signal in 1MHz is sent to a frequency divider 22 and a microcomputer muCP 15 detects the application of power to stop the output of a carrier original signal from the frequency divider 22. When the operator operates a switch 21 to start the transmission operation, the muCP 15 detects it to send a carrier transmission signal based on the content of a text to the frequency divider 22. Then a 125kHz carrier transmission signal is outputted from the frequency divider 22 only at the time of transmitting the signal and outputting to a transmission circuit 18 as a tone burst signal from an output terminal P1. Since a carrier original signal control means controlling the carrier original signal to be outputted from the frequency divider 22 only at the time of transmitting the carrier transmission signal to the muCP 15, 15A, the carrier original signal is outputted in a very short time and the invasion of high frequency noise is suppressed at the time of receiving the AM radio broadcast.

Abstract: PURPOSE:To realize accurate setting of an angle of rotation of a rotary shaft by forming stopper parts on both sides of the rotary shaft and forming a cam groove between these stopper parts and further fitting said groove to a sliding member through a seal member. CONSTITUTION:Flat stopper parts 7, 8 are formed on both sides of a rotary shaft 4 and a spiral cam groove 9, which has the bottom part of the same shape in the direction perpendicular to the shaft as those of the stoppers 7, 8, is continuously formed between the stoppers 7, 8, while the cam groove 9 is fitted in a sliding member 10 through a seal member 18. Thus, an angle of rotation of the rotary shaft 4 comes to be gradually increased, constant and gradually decreased during process of its rotation from starting to finishing. Therefore, its rotational condition grows smooth and unnecessarily strong force is prevented from being applied on the rotary shaft at times of starting and finishing of rotation. Accordingly, the angle of rotation of the rotary shaft 4 can be accurately set without using the stopper separately.

IPC: G11B5/39
Filed: 1982-07-08
Abstract: PURPOSE:To detect a magnetic field bearing in a broad dynamic range, by providing uneven part on the surface of a substrate of a magnetoresistance effect (MR) element, aligning anisotropy in the uneven direction, increasing the magnitude of an anisotropic magnetic field by the uneven part, and enlarging a linear region. CONSTITUTION:Steps 12 are formed on the surface of a square substrate 14, on which an MR film 11 is to be deposited, so that the steps form 45 degrees with a current (i) that is flowed to the MR film 11. Electrodes 13 are provided at both ends of the MR so that the current can be uniformly conducted in the film. When the film 11 is evaporated on the substrate, the axis of the MR film 11, which can be readily magnetized, is directed to the direction along the uneven parts of the surface. The magnitude of an anisotropic magnetic field HK can be controlled by the repeating pitch and depth of the unevenness of the surface. When a magnetic field H is applied at a right angle with respect to the uneven direction, the change is resistivity delta0 indicates a straight line and has the maximum value when the H is small, and the polarity of the magnetic field can be judged. When the H is applied in parallel, the change is small and the value of change becomes the minimum in this direction. The relative angle between the magnetic field and the element can be read by comparing both values.
