Patent JP-H02281531-A (JP)
Title: Diode and its manufacture
Inventor: IBU RIYUDAN
IPC: H01J9/12
Filed: 1990-03-12
Abstract: PURPOSE: To manufacture a diode on a substrate continuously by maintaining consistently an inert atmosphere of the boundary between a first layer made of Au or Pt and a secondary layer made of a metal oxide which has a secondary electron emission characteristic. CONSTITUTION: A polished substrate 2 is filmed with a first layer 4 made of Au or Pt so as to be thick enough to form a diffusion barrier at a temperature of 500 deg.C or less, using cathode spattering In an inert atmosphere. Then, a second layer 6 made of a metal oxide which has a secondary electron emission characteristic is formed on the first layer so as to be thick enough to pass an electron through the layer by the tunnel effect, using cathode spattering in an inert atmosphere. The boundary condition between the first layer 4 and the second layer 6 is maintained consistently in an inert atmosphere. Under this condition, a diode can be formed on the substrate continuously. Furthermore, this simple manufacturing method of diode assures its long life with a stable yield.

Title: Multilayer film reflecting mirror and method for manufacturing it
Inventor: ISHIYAMA WAKANA
IPC: G21K1/06
Filed: 1999-03-05
Abstract: PROBLEM TO BE SOLVED: To deter a multilayer film of a multilayer film reflecting mirror used in a soft X-ray range from exfoliating by forming an alternate multilayer film made of a substance with high refractive index and one with low refractive index only in a reflecting area of a substrate. SOLUTION: A notch 1c is formed in a part of a substrate 1, and a chamfered face 1b is made all around the outer periphery of a ground surface 1a. A film is formed only in the ground surface 1a of the substrate 1 by covering the notch 1c and the chamfered face 1b that are not covered with a holder 3 for fixing the substrate 1 with an adhesion preventing plate 4. On this occasion, a spacer 5 is inserted in order not to displace the substrate 1 in the holder 3. Then, an alternate multilayer film is formed on the ground surface 1a of the substrate 1 by putting it in a vacuum chamber of a film forming device and forming a film made of a substance with high refractive index and one with low refractive index.  A multilayer film reflecting mirror where an alternate multilayer film is formed only in the ground face 1 can be obtained by taking out the substrate 1 from the inside of the vacuum chamber and detaching the holder 3, the spacer 5 and the adhesion preventing plate 4 after the formation of a film.

Title: Compound semiconductor device
Inventor: YOSHIKAWA SHUNEI
IPC: H01L29/778
Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a compound semiconductor device whose threshold voltage is high and whose gain is also high by forming a relaxation layer of a prescribed thickness on an electron travelling layer, setting a barrier layer to a prescribed thickness and making the composition ratio of Al to be larger than the relaxation layer. SOLUTION: A buffer layer 12 is formed on a semi-insulating GaAs substrate 10. The electron travelling layer 14 whose thickness is 14nm, whose composition ratio (z) of In is 0.2 and which is constituted of In2 Ga1-z As is formed on the buffer layer 12. A relaxation layer whose thickness is 5nm, whose composition ratio (x) of Al is 0.25, whose composition ratio (y) is 0.95 and which is constituted of (Alx Ga1-x )y In1-y As is formed on the electron travelling layer 14. The thickness of the relaxation layer 16 may be within a range of not more than 10nm. A barrier layer 18 whose thickness is 15nm, whose composition ratio (x) of Al is 0.75 and which is constituted of Alx Ga1-x As is formed on the relaxation layer 16.  Since the relaxation layer 16, to which Al is added slightly, is formed below the barrier layer 18, junction with the barrier layer 18 to which Al is added becomes satisfactory. It is sufficient that the thickness of the barrier layer 18 be within a range of not more than 20nm.

This allows provision of heat insulation, heat-retention, and cushion characteristics for a seat of a structure where the seat is not shielded from outside air. Even when the seat gets wet in rain, almost equal comfort is restored compared to that obtained when it is dry.

Title: Vehicle motion control device

IPC: B60T8/66
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To perform desired motion control by computing a suitable estimated body speed, depending on the motion status of a vehicle, regarding a vehicle motion control device. SOLUTION: Brake force applied to each wheel is controlled by means of a brake force control means BC, based on an estimated body speed calculated for every wheel with an estimated body speed operation means ES, and a wheel speed detected with a wheel speed detection means WS. In this case, a lateral difference limit value operation means DF computes the limit value of an estimated body speed difference between vehicular right and left wheels.  In addition, a control means LM imposes a limit on the operation of the estimated body speed for one of the right and left wheels, so that the estimated body speed for one of the right and left wheels having a relatively low wheel speed is not below a value resulting from the subtraction of the limit value of an estimated body speed difference for the right and left wheels computed with the lateral difference value operation means DF, from the estimated body speed for the other wheel having a relatively high wheel speed.
