Patent JP-S6177817-A (JP)
Title: Zoom lens
Inventor: TANAKA KAZUO
IPC: G02B15/167
Filed: 1984-09-25
Abstract: PURPOSE:To correct satisfactorily comatic aberration and halo and to have high optical performance by changing part of the lens constitution of a relay system to shift a variable power range and disposing a limiting stop nearer on the image plane side than the change part of a relay part. CONSTITUTION:The decrease in the optical performance is prevented by inserting a built-in extender into a lens and disposing a limiting stop 56 between the built-in extender and the image plane, more specifically behind the changing part of the relay system to shield part of off-axis luminous flux omega1. The position of the limiting stop is between the built-in extender and the image plane and may be any position where a part of the off-axis luminous flux except the axial luminous flux is shielded. The luminous flux above the flux omega1' changes from the luminous flux 57 to the luminous flux 57'. The coma aberration and halo are thus satisfactorily corrected. There is an embodiment in which the luminous flux corresponding to a region 61 is shielded by disposing the limiting stop behind the built-in extender to remove the comatic aberration and halo. There are a method for dividing the relay system into the two lens groups; front group and rear group and inserting the built-in extender between the two lens groups and other methods as the variable power method.

Title: Test method for drying characteristics of castable refractory
Inventor: YAMAMURA TAKASHI
IPC: C04B35/66
Filed: 1993-07-20
Abstract: PURPOSE:To provide a relatively simple and practical method for testing the drying characteristics of castable refractories. CONSTITUTION:Pressure of steam generated in a structure is predicted by measuring the temperature in the structure. A sample 1 of the structure is thrown into a furnace 3 held at a predetermined temperature (200-600 deg.C) and the internal temperature of the sample 1 is measured. Temperature is read out upon finish of constant rate drying operation and the pressure of generated steam is predicted based on the temperature thus read out. This method requires about 30min for measurement of one sample and allows relatively simple mass measurement. Consequently, the temperature rise rate can be set easily and accurately for each structure when the structure of castable refractories are dried.

Title: Semiconductor laser
Inventor: DOI KEIICHIRO
IPC: H01S5/00
Filed: 1990-07-27
Abstract: PURPOSE:To reduce generation of a spike and to reduce unnecessary power consumption based on a voltage drop by forming an intermediate layer exhibiting a composition change continued from the composition of one layer to the composition of other layer between layers formed with current narrowing parts having different energy bands between a contact layer and a clad layer. CONSTITUTION:A first intermediate layer 50 is formed between a P-type contact layer 12 and a ridge layer 14, and a second intermediate layer 52 is formed between the layer 14 and a P-type clad layer 16. The compositions of the layers 50, 52 are sequentially varied to adjacent layers. Thus, the composition is continuously varied from the layer 12 to the layer 16. Accordingly, since an energy spike generated in a hetero junction of a conventional structure is not generated and a voltage drop due to a hetero junction does not occur, a desired optical output can be obtained at a low voltage.

From the stand point of increasing the pass band to be 18kHz or over, the ΔF is desirably 45kHz or over.  The ΔF of the resonators with the small ΔF is selected to be 25kHz or over, because the pass-band width becomes narrow and the characteristic deteriorates when the ΔF is selected smaller than 25kHz.

Abstract: PURPOSE:To improve the property of heat dissipation by enlarging the contact area of a piston with a metal to be processed, using a magnetic fluid, and to enable moderate contact with a semiconductor element and the prevention of piston removal by a method wherein the space between the metal and the piston is made air-tight. CONSTITUTION:The gap between a cylindrical recess 3 and the piston 4 is filled with the magnetic fluid 10 containing a metal as the main constituent, and the heat resistance is made much smaller by secure surface-contact of the recess with the piston by the magnetic suction force acting on the fluid. Further, the piston is brought into contact with the semiconductor element 5 under a positive pressure produced in a space 8 by the air-tightening of the space due to the action of the fluid. Besides, in the case of removing a card assembly including the elements and a wiring substrate 6 for the purpose of repairing and the like, the removal of the piston dus to a negative pressure produced in the space is prevented. The metal 2 to be processed is cooled to a suitable temperature by a cooling liquid flowing through a passage 1, and the piston contacts with the element under a moderate pressure and then transfers the heat of the element to the metal.
