Title: Substrate coated with thin boron nitride film and its production
Inventor: NISHIYAMA SATORU
IPC: C23C14/48
Filed: 1990-03-30
Abstract: PURPOSE:To increase hardness and also to improve adhesive strength by regulating the ratio of the number of particles between B atoms and N atoms in a thin BN film so that it is increased intermittently or continuously with the approach from the surface of the thin BN film to the surface of a substrate. CONSTITUTION:Simultaneously with, alternately with, or after the vapordeposition of a substance containing B element from an evaporation source 3 onto the surface of a substrate 2, the surface is irradiated with ions 6 containing N element from an ion source 5. At this time, a thin BN film is formed on the surface of the substrate 2 while measuring and controlling the amount of vapor deposition of a vapor deposition material 4 and the amount of irradiation of the ions 6 by means of a film thickness gage 7 and an electric current measuring instrument 8 so that the ratio of the number of particles between B atoms and N atoms in the thin BN film is increased continuously or intermittently with the approach from the surface of the thin BN film to the surface of the substrate 2. As a result, not only the hardness of the resulting thin BN film is increased, but also the adhesive strength of this film to the substrate 2 is increased and the occurrence of peeling can be prevented even under high temp. conditions.

Title: Large-sized liquid crystal display device
Inventor: YAMAMOTO KAZUKO
IPC: G02F1/1335
Filed: 1989-04-05
Abstract: PURPOSE:To make a display on a screen easy to see and to improve the display quality of the screen by coloring the external frames of individual liquid crystal display elements chromatically. CONSTITUTION:The display screen 10 has picture elements of red 13, green 14, and blue 15 arranged in delta array and black stripes 12 are constituted between the picture elements. Further, a metallic frame 11 which holds the liquid crystal display elements 9 becomes a non-display part when viewed on the whole and the part of the metallic frame 11 is colored chromatically, e.g. in brown. Therefore, when this device is viewed at such a distance that colors are mixed, the brown frame 11 is color-mixed with the display screen 10 to make it difficult to see the contour of the external frame 11 clearly, so the external frame 11 becomes inconspicuous. Consequently, the display screen becomes easy to see and the display quality can be improved.

IPC: E04B1/70
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To make a ventilator readily reformable by fixedly providing a blower having a motor-driven fan to a main body consisting of a box which has an inlet port and an outlet port in the frame body of a readily-set ventilator which is set on a ceiling or the like and has an opening that faces the interior of a room and an opening for exhaust air. SOLUTION: A main body 6 of a blower 1a is fit to a frame body 1 so that the side of the frame body 1 having an outlet 18 coincides with the side of the main body 6 having an opening 6a. In this case, a cushion 8 attached to the periphery of the opening 6a of the main body 6 fills up the gap between the side of the frame body 1 having the outlet 18 and the end portion of the opening 6a of the main body 6. The frame for fixing the main body is fixed by directly fixing a roof surface 3a to an upper inside of the frame body 1 by means of a special screw 5. Such a manner of fixture offers an advantage of readily reforming a ventilator without damaging a ceiling.

Title: Pipe fitting structure of manhole
Inventor: IIKAWA YASURO
IPC: E02D29/12
Filed: 1997-04-04
Abstract: PROBLEM TO BE SOLVED: To prevent damage such as a crack at a pipe fitting part of a manhole by interposing a displacement absorber between sheet piles and reinforced concrete. SOLUTION: A clearance is provided between reinforced concrete 5 and sheet piles 4a engaged with pipes 3 at the time of constructing a manhole and remain in earth. A displacement absorber 10 easy to deform such as styrene foam or rubber material is disposed in the clearance. Displacement of the sheet piles 4a caused by earth pressure P is therefore absorbed by the displacement absorber 10 so as to reduce pressing force to a pipe fitting wall 2 through the reinforced concrete 5 and thereby to prevent the damage such as a crack of the manhole 1. In order to prevent the manhole 1 from being influenced by the displacement of the sheet piles 4a, the displacement absorber 10 can be arranged between the sheet piles 4a and the reinforced concrete 5.

Abstract: PURPOSE:To perform reuse of a filter without reducing a regeneration efficiency under an operation condition in a wide range by providing a flow control valve at the upstream side of an exhaust system branched into two passages each provided with a filter, an exhaust throttle valve, and a combustion support means. CONSTITUTION:An exhaust system 2 of an engine 1 is composed of branched passages 6, 7 branched into two via an upstream passage 4 connected to an exhaust gas mainhold 3 and a branched part 5 and a downstream passage 8. At the branched part 5, a branch valve 12 is provided.

Since exhaust gas temperature and oxygen concentration are increased, a proper regeneration effect is secured. Since exhaust gas is partially discharged through the branch passage 7, a working condition of the regeneration of filters 9a, 9b is remarkably moderated and decrease in the temperature of the filter 9b is prevented.

Title: Optical information recorder
Inventor: TSUBOI NOBUYOSHI
IPC: G11B7/00
Filed: 1987-04-08
Abstract: PURPOSE:To record and erase information at high speed and, at the same time, to prevent occurrence of insufficient erasing of information, by projecting both spots of natural light and laser beam upon an optical recording medium, with the natural light spot preceding the laser beam spot in the moving direction of the medium. CONSTITUTION:An optical means which projects a spot of laser beam (i) and spot of natural light (n) which is larger than the spot of laser beam closely to each other upon an optical recording medium 14 is provided and both spots are projected upon the medium 14 under a condition where the spot of the natural light (n) precedes the spot of laser beam (i) in the moving direction of the medium 14. Since sufficiently high output one can be obtained for the light source of the natural light, the energy density of the natural light spot can be made sufficiently high on the recording medium and the spot of the natural light (n) can make preheating works by heating wide areas preceding the laser beam spot on the optical recording medium 14. Therefore, the temperature raising time can be made shorter and high-speed recording and erasing of information or recording, while erasing is made, can be realized. Moreover, since heating can be performed at the high energy density, all information to be erased can be erased completely at the time of erasing.

Abstract: PURPOSE:To suitably control a trolling engine speed (the minimum engine speed) according to an atmospheric temperature by constituting an ignition timing switch means in such a manner as to include a temperature sensor capable of varying a delay angle of an output signal according to the temperature. CONSTITUTION:Using a waveform output on plus sides of pulser coils 39, 40 as a start signal, a gear count circuit 51 counts a pulse of a gear count coil 52 during a time determined on the basis of a resistance value set by a thermistor 10 and a predetermined value of a capacitor, to generate an output upon completion of counting. A signal distribution circuit 48 converts the output of the gear count circuit 51 into a second trolling ignition timing signal, which is supplied to gates of thyristors SCR1, SCR2, to thus turn on the gates. Therefore, ignition can be carried out at any timing of ignition timings theta1-theta2 at the time of trolling, thereby obtaining a stable trolling engine speed.
