Title: Rear focus conversion lens for telephoto lens
Inventor: HAMANISHI YOSHINORI
IPC: G02B7/28
Filed: 1983-07-28
Abstract: PURPOSE:To obtain a general conversion lens (RFC) which is focused speedily and exhibits excellent image formation performance by giving negative refracting power, moving respective groups of the RFC of three-group constitution at different speeds and generating opposite-directional aberrations, and satisfying specific inequalities. CONSTITUTION:The three groups G1, G2, and G3 of the RFC move at different speeds during focusing to obtain adjacent intervals D1, D2, and D3, and extents DELTAD1, DELTAD2, DELTAD3, and DELTABf of an increase or decrease in the distance Bf to a film plane 21. The inequalities I -V hold, where alpha, alpha1, alpha2, and alpha3 are ratios to the variation extents DELTATL and DELTABf of the overall length TL', and beta is an expansion rate of focal length. The inequality I corrects aberrations and simplifies the structure, and the inequalities II and III correct the spherical aberration and the inequality IV optimizes the astigmatism, and the inequality V prevents a decrease in the refracting power of the RFC, improving the distance measurement precision. Therefore, this RFC is used for various telephoto lenses, speedy focusing is attained with the simple constitution, and excellent image formation performance even in short-distance focusing is maintained.

Title: Manufacture of infrared ray emitting diode
Inventor: SHIOSE NOBUYUKI
IPC: H01L21/208
Filed: 1986-06-13
Abstract: PURPOSE:To form a P-type layer in which an Si concentration is nearly constant by composing the P-type layer out of plural layers and using a melt for liquid- phase epitaxy of an upper P-type layer, in which an Si concentration is lower than a melt used for growing an underlying P-type layer. CONSTITUTION:On an N-type GaAs single crystal substrate 1, an N-type layer 2 is epitaxially grown by bringing a Ga melt doped with Si and GaAs in touch. By using this melt, a first P-type layer 3 is continuously grown by epitaxy. Then, the melt used for epitaxial growth of an i-th (i is an integer which is at least 1) P-type layer is removed and an (i+1)-th P-type layer is epitaxially grown while bringing a substrate in touch with a Ga melt including Si and GaAs by a lower concentration than said removed melt. These steps are reapeated from i=1 to n (n is an arbitrary integer.). This prevents an increase of an Si quantity in a thickness direction of growth caused by an influence of a segregation coefficient.

Filed: 1998-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent a seat part from being rotated unexpectedly to cause overturning of a person by providing a rotation braking means between a support cylinder and a rotating shaft, where the braking force is increased as the relative rotation amount between the cylinder and the shaft is increased. SOLUTION: When a person sits on a seat part 2 to turn the seat part 2 with respect to a leg part 1, a rotating shaft 4 is rotated with respect to a support cylinder 15. A coil spring 6a which is externally fitted to the rotating shaft 4 through a braking cylinder 5 and has a fixed part fixed to the support cylinder 15 is rotated in the direction of increasing the number of turns, and the other spring 6b is rotated in the unwinding direction. Thus, the coil spring 6a rotated in the direction of increasing the number of turns is reduced in its inside diameter, and by the reduction of inside diameter of the coil spring 6a, the inside diameter of the braking cylinder 5 is reduced, so that, as the rotation amount is increases, the frictional force is increased to brake the rotation of the seat part 2.  In the case of rotating the seat part 2 in the opposite direction, the other coil spring 6b is rotated in the direction of increasing the number of turns to brake the rotation in the other direction.

Title: Coaxial matching circuit
Inventor: IMAI TAKEO
IPC: H01P1/202
Filed: 1979-10-25
Abstract: PURPOSE:To obtain a coaxial matching circuit of a simple structure, by giving a vertical connection to the 1/4-wavelength coaxial lines having different characteristic impedances and then using some of the above-mentioned coaxial lines for the low pass filters to block the propagation of the undesired wave. CONSTITUTION:The LPF type 1/4-wavelength transformer 13 consists of the coaxial lines 131-133 having different characteristic impedances Za, Zb and Za each. The characteristic impedance is set as Z0 for both the circulator and the coaxial line 15, and the characteristic impedance of the coaxial line 3 is set as Z1. And the impedance ZL is set for the coaxial line 18 and the varactor diode 1, and the length is selected at lambdaU/4 with the unnecessary frequency fU and for the lines 131-133. Thus the line between B and C is turned into the 3/4-wavelength impedance transformer at fU, and the impedance becomes as ZC=Zb<4>/(Za<2>+ZL) when  viewed from the point C. Accordingly, the propagation of the undesired wave fU can be blocked by reducing the ZC enough after selecting Za and Zb. Thus the individual parts of the circuit can be eliminated. As a result, the struture can be simplified, thus realizing a device having a high resistance to the undesired wave.
