Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To enable high temp. high output operation at a specified visiblle range, by using a specified mixed crystal semiconductor contg. N as a component element in a light emitting layer. SOLUTION: A lower reflection mirror 201, a light emitting layer 202 and an upper reflection mirror 205 are laminated on a crystal substrate 101 to form a surface-emitting semiconductor laser element for radiating a light in a direction perpendicular to the crystal substrate 101. The light emitting layer uses an N-contg. Gax In1-x Ny P1-y mixed crystal semiconductor as a component element, Gax In1-x Ny P1-y is a 4-element mixed crystal material contg. N as a V group element introduced in a Gax In1-x P 4-element mixed crystal, and the inhibition band of Gax In1-x P is in the range of 1.35-2.24 eV for direct transition and when N is a little introduced in Gax In1-x P, its inhibition bandwidth reduces about 150 eV with 1% of the N compsn. Hence Gax In1-x Ny P1-y enables the light emission at a 0.6 μm band.  The conductive band discontinuity to a barrier layer is high and hence the high temp. high output operation is enabled at the 0.6 μm band.

Title: Manufacture of coaxial cylindrical type torque limiter
Inventor: FUJIOKA TERUO
IPC: H02K49/10
Filed: 1997-05-06
Abstract: PROBLEM TO BE SOLVED: To improve quality of a product and productivity by multipole- magnetizing the outer circumferential face of a cylindrical permanent magnet, after adhering a non-magnetized cylindrical permanent magnet to the outer circumferential face of a rotary shaft. SOLUTION: Adhesive 32a is applied on the outer circumferential face of a rotary shaft 31, a non-magnetized cylindrical permanent magnet 1' is coveredly fitted onto it and pressed down. When the adhesive 32a is hardened, the permanent magnet 1' is stuck to the rotary shaft 31 through an adhesive layer 32. Next, the permanent magnet 1' and the rotary shaft 31 are inserted inside a magnetized yoke Y. Further, current (i) is flowed to respective coils, and adding magnetic flux F (the directions of magnetic flux generated in adjoining magnetizing yokes are opposite to each other) to the permanent magnet 1', the outer circumferential face of the permanent magnet 1 is multipole- magnetized so that the respective magnetic pole territories of N-poles and S-poles in parallel with the axial direction are alternately formed in the circumferential direction.  Hereby, it is unnecessary to spread the distance to the other permanent magnet considering the influence from a magnetic field by the permanent magnet, and hence a working space can be saved.

Title: Correction of deflection strain at charged beam exposure device
Inventor: TAKAMOTO KIICHI
IPC: H01J37/304
Filed: 1982-07-05
Abstract: PURPOSE:To enhance the precision of positioning of a charged beam onto the surface of a sample by a method wherein deflection strain at the level surface of the arbitrary height is measured precisely to obtain the correction formulas of deflection strain. CONSTITUTION:The charged beam is focused in height (z1) of the level surface to measure deflection strain. The correction equations of deflection strain at the level surfaces of the same heights with a low standard mark and a high standard mark are decided using the standard marks of the two faces of high and low holding the focus in this condition as it is. Then, the values of Ai(z1), Bi(z1), (i=0-9) are calculated performing substitution as z=z1 at the formula I . As a result, the equations II can be obtained as the correction equations of deflection strain at height (z1). Because the position of the focus of the beam is not altered when the formulas II are obtained, the beam injected on the surface of the sample comes moving on a straight line. Accordingly, the quantity of deflection strain measured according to the standard marks of the two faces of high and low can be expressed by the linear function of height (z), and the formula II have the coefficients of the more precise values as the correction formulas of the deflection strain at height z=z1 than the usual method.

Title: Fm modulator
Inventor: TAKANO TAKESHI
IPC: H03C3/00
Filed: 1977-09-29
Abstract: PURPOSE: To produce a FM modulator which can perform FM modulation stably even if the level of modulated signals is made higher and uses the phase synchronous oscillation period generating no step-out, by providing further an AFC loop dependent upon a frequency discriminator outside the phase synchronous loop.  
     CONSTITUTION: Output S 1  of oscillator 2 which has the oscillated frequency changed by the applied voltage and the phase of reference signal S 1  are compared with each other in comparator 4, and signal S 3  corresponding to the difference and S 4  obtained by controlling S 1  by frquency discriminator 5 are added in adder 6. Added signal S 5  is applied to control terminal 2a of oscillator 2 through LPF, and further, input modulated signal S 7  is amplified and applied to this terminal. Center frequency fO of oscillator 2 is held at a prescribed value by S 6  and is subjected to FM modulation by S 7 , and output S 1  is taken out from terminal 9. Since output S 1  is also controlled by frequency discriminator 5, no step-out is generated even if the level of modulated signals is made higher or the setting of a leading-in range is shifted by temperature change and so on, that f 0  can be maintained with a high precision

Title: Toothbrush with hair planted unevenly and high at middle
Inventor: NAKAYAMA ICHIJIRO
IPC: A46B9/04
Filed: 1990-05-01
Abstract: PURPOSE:To obtain the toothbrush so that it can brush up cleanly between a tooth and a tooth by assembling its hair so that its middle becomes higher and both its ends become lower in height. CONSTITUTION:A conventional toothbrush cannot brush up cleanly between a tooth and a tooth since the lie of hair is a plane. Therefore, the middle of the toothbrush is made high to some extent and the ends are made low so that it can brush up cleanly between teeth. As for the lie of hair, a suitable assembly is necessary, and unless the middle is not assembled by a suitable lie of hair, both ends cannot be brushed up enough. Accordingly, it is necessary to assemble suitably the lie of hair. This toothbrush is assembled by making the hair uneven, the middle high and both the ends low in height, and can brush up horizontally or vertically.
