Title: Magneto-optical recording medium and its production
Inventor: YAMADA TAKASHI
IPC: G11B7/24
Filed: 1986-10-17
Abstract: PURPOSE:To prevent oxidation of a magneto-optical recording layer from the side faces thereof and to prevent the deterioration in recording and reproducing characteristics and degradation in appearance by providing rare earth metal layers to the side face of the recording layer. CONSTITUTION:This magneto-optical recording medium 1 is formed by laminating a 1st transparent dielectric protective layer 3 and the magneto-optical recording layer 4 on a circular nonmagnetic transparent substrate 2 bored with a hole for insertion of a spindle shaft, forming the rare earth metal layers 5a, 5b over the entire surfaces on the inside and outside of the layers 3, 4 and forming a 2nd transparent dielectric protective layer 6 so as to cover the entire surface thereof. More specifically, the oxidation of the recording layer 4 is prevented by providing the rare earth metal layers 5a, 5b which are liable to absorb oxygen over the entire surface on the inside and outside of the recording layer 4 and trapping the oxygen infiltering from the side faces which cannot be blocked by the layers 3, 6. The recording and reproducing characteristics are thereby improved and the generation of cracks, pits, pinholes, etc., is decreased to a greater extent.

Title: Surface emitting laser
Inventor: YOSHIKAWA TAKASHI
IPC: H01S5/00
Filed: 1994-10-13
Abstract: PURPOSE: To control the direction of the polarized light of a vertical resonator- type surface emitting laser so as to be well-ordered. CONSTITUTION: A post-shaped anode-side semiconductor multilayer reflection film 2 is tilted. A reflection on a side face depends on polarized light, and the reflection factor of polarized waves which are parallel to a slope is high. As a result, it is possible to obtain polarized light which is parallel to the slope. In addition, when a cross-sectional shape is formed as a rectangle, the loss of polarized waves perpendicular to a long side is large on the side of the long side. As a result, it is possible to obtain polarized light perpendicular to the long side.

Title: Semiconductor device
Inventor: KATO TAKUYA
IPC: H01L21/768
Filed: 1990-09-18
Abstract: PURPOSE:To improve the adhesion and reliability of a semiconductor device by successively forming a thin porous metal oxide film and the second organic insulating film on the entire surface of a conductive film constituting wiring after the conductive film is formed on the first organic insulating film constituting a layer insulating film. CONSTITUTION:Since a wiring section has such a structure that a hafnium oxide film 5 exists between an aluminum film 4 constituting wiring and a polyimide film 6 constituting a layer insulating film or cover insulating film, the adhesion between the films 4 and 6 is excellent. In addition, since the hafnium oxide film 2 between an organic siloxane polymer film 2 and the polyimide film 6 is porous, the gas produced from the film 2 when heat treatment is made to harden the polyimide film 6 can be led to the outside and the adhesion between the films 2 and 6 can be maintained in an excellent state.

IPC: H04N1/23
Filed: 1989-09-25
Abstract: PURPOSE:To keep excellent recording picture quality and to improve the recording speed as a whole by varying the recording speed to 2 stages or over to decrease the recording speed as a coded data quantity is large. CONSTITUTION:An EOL detection section 7 detecting a line delimiter EOL code of a coded data, a count section 8 counting an EOL detection signal from the EOL detection section 7, and a speed decision section 9 deciding the recording speed in response to the code data quantity per one line for each page and outputting the result as a recording speed signal 1 are provided to the method. The recording speed is varied for 2 stages or over so as to decrease the recording speed as the coded data quantity per one line for each page or each prescribed line number. Thus, the entire page for characters and line drawing or the like or character and line drawing portions in a page are recorded as high as possible and the intermediate tone portion keeps excellent recording picture quality by decreasing the recording speed thereby increasing the recording speed as a whole considerably.

Title: Opening and shutting roof for vehicle
Inventor: SMITH ROBERT
IPC: B60J7/06
Filed: 1996-09-19
Abstract: PROBLEM TO BE SOLVED: To simplify a locking operation by laying a transmission mechanism between a latch member and a drive means for pressing a control beam to a forward position with a larger drive force at a final closing process. SOLUTION: A lock pin 18 is engaged with a locking slot part 19" and this engagement status is maintained with a spring member 20 energizing a latch member 13. Among the walls of the locking slot part 19", the wall faced to the front part of an open/close roof forms sliding space. Thus, when the lock pin 18 also stays within the part 19", when a force for pulling back the latch member 13 is applied. Furthermore, a lever 10 is locked against rotation, due to the constraint of the latch member 13 along the lengthwise direction of the open/close roof. A fixed connection between a front plate and a slide shoe is ensured, due to the constraint of the lever 10. As a result, a control beam 4 follows various travel modes of the slide shoe at a ratio of 1:1.

CONSTITUTION:The pressure in a pressurized chamber constructed of a heat- insulation material and pressure-resistant material is controlled by the difference between the amount of sucked air and that of exhausted air until the air pressure in the chamber becomes constant. A water-containing material is stored in the chamber under a constant pressure. At the same time, the temperature in the chamber is maintained to the optimum level by an air-conditioner according to the kind of the water-containing material to be stored.

Title: Slope protection method and slope protection block therefor
Inventor: IMAI MINORU
IPC: E02D17/20
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent a slope from swelling or collapsing, by providing a vegetation zone planting vegetation between slope protection blocks and forming the vegetation zone composed of the first soil layer having a hardness which does not allow rooting and the second soil layer having a hardness which allows rooting. SOLUTION: A plurality of slope protection blocks 3 are assembled on a slope 1 and vegetation zones 4 are formed therebetween. In this vegetation zone 4, a specified thick soil layer 12 containing clay is formed so as not to allow rooting plants S on the slope 1 and a surface soil layer 13 to allow rooting the plants S is formed on the soil layer 12. Since the soil layer 12 of the vegetation zone 4 is relatively hard, water is prevented from penetrating to the slope 1 to prevent the slope from swelling or collapsing. The plants S can root only in the surface soil layer 13 and hence, growing of the roots of the plants S can be prevented. Since the surface soil layer 13 has a thickness enough to root low trees, greening is realized.
