Title: Unipotential type electronic gun
Inventor: OGAWA YOUJI
IPC: H01J29/48
Filed: 1977-11-29
Abstract: PURPOSE: To increase the resolution of the color Braun tube by securing the optimum ratios between the length and the inner diameter of the grid, between the grid space and the inner diameter and between the focus voltage and the screen voltage respectively.  
     CONSTITUTION: For the unipotential type electronic gun which is used to the shadow mask type Braun tube and the like, length l 4  of 4th grid 5 is set to 0.8W 1.2D (D: grid inner dia.) with space S set to 0.15W0.35D between grid 5, 3rd grid 4 and 5th grid 6 respectively. At the same time, the grid voltage (focus voltage) Ec4 is set to 0.26W0.30 Es (Es: screen voltage). As a result, both the magnification ratio and the aberration can be reduced for the main lens, thus obtaining a small beam spot even with a large amount of current. Thus, a high-resolution picture can be obtained via such electronic gun.

Title: Method and apparatus for measuring flexibility of flexible body
Inventor: KOJIMA TOUSAKU
IPC: G11B5/84
Filed: 1984-07-11
Abstract: PURPOSE:To measure the flexibility of a flexible body such as a magnetic recording medium or the like, by suspending vertically the body to be measured, by applying sweep oscillation thereto from the fixed end side, and by determining the amount of amplitude from a reflected light obtained by the application of a light. CONSTITUTION:A magnetic tape 10 is suspended vertically with one end clamped by a clamp 20, while it is made free at the lower end thereof. The clamp 20 is made to vibrate sinusoidally by a vibrator 22 connected to a variable-frequency oscillator 23, and thereby a vibration is given to the magnetic tape 10. When a light of an incandescent lamp 50 is applied to the magnetic surface 11 of the tape 10 through a lens 51, a reflected scattered light is formed as an image on an optical displacement detection mechanism 53 through a lens 52. This transfer is detected by a divider 57, the amount of vibration of the tape 10 is measured therefrom, and the relationship between a sweep frequency and the amount of amplitude is AD-converted by an AD converter 32. From the relationship between a signal thus obtained and a signal obtained through AD conversion of a frequency from the oscillator 23, a resonant frequency and a band width are determined by a processor 33, and a dynamic elasticity modulus, etc. are calculated therefrom.

Title: Thin film magnetic head
Inventor: YAMADA KAZUHIKO
IPC: G11B5/31
Filed: 1983-08-04
Abstract: PURPOSE:To realize excellent write/read efficiency at a low cost by forming a thin film magnetic head in which the coercive forces Hc, Hc', magnetic permeabilities mu, mu' and satd. magnetic flux densities B, B' of the 1st and 2nd soft magnetic materials constituting a lower magnetic material layer and an upper magnetic material layer have respectively the relations Hc>=H'c, mu<mu' and B<B'. CONSTITUTION:The coercive force H'c and magnetic permeability mu' of the 2nd soft magnetic material constituting an upper magnetic material layer 27 have the relations H'c<=Hc, mu'>mu with the coercive force Hc and magnetic permeability mu of the 1st soft magnetic material constituting a lower magnetic material layer 23 and therefore the influence of the deterioration in the magnetic characteristic in the step part B or B' shown by an arrow is relatively small. The satd. magnetic flux density has the relation B'>B and therefore even if the film thickness T' of the layer 27 is T'<=T with respect to the film thickness T of the layer 23, magnetical satn. arises hardly and the excellent write/read efficiency is realized. Since there is no need for increasing the film thickness of the layer 27, the above-mentioned way is considered to have extremely important significance in the process for producing the thin film magnetic head.

Abstract: PURPOSE:To form a graphic and a waveform to meet the rules of a graph sheet by converting the coordinates of a lithographic command input from the corresponding relationship between a graph sheet coordinate system and a graphic lithography coordinate system into the coordinates of the graphic system. CONSTITUTION:Rules printed on a graph sheet (g) are optically detected to obtain the corresponding relationship between a graph sheet coordinate system G and a graphic lithography coordinate system P. When a lithography command is inputted, the coordinates Zc of the command is regarded as the coordinates Zg of the system G, and converted to the coordinates Zp of the system P according to the relationship. The command is executed for the coordinates Zn. Thus, according to an X-Y plotter 1, even if the sheet (g) is elongated or contracted, the graphic can be formed to meet the rules. As a result, the rules of the sheet (g) can be used as a scale, and the size, etc., of the graphic can be accurately read.
