Title: Coupling device between light emitting element and optical fiber
Inventor: KITACHI NISHIMINE
IPC: G02B6/42
Filed: 1984-07-09
Abstract: PURPOSE:To prevent the degradation of the coupling efficiency due to the secular change of the adhesive strength and flux by fixing individual parts to one another by welding after three-dimensional position adjustments between a metallic cylinder holding a light emitting element and an optical fiber holding member. CONSTITUTION:The light emitted from a light emitting element 17 is coupled to an optical fiber 12 by a spherical lens 16. For the purpose of obtaining a maximum coupling efficiency in this case, three-dimensional position adjustments of the light emitting element 17 are performed. The light emitting element 17 is slid in a metallic cylinder in the Z direction to adjust the position of the light emitting element 17 in the Z direction. In this case, the metallic cylinder 20 is brought into contact with the end part of a receptacle 14. The light emitting element 17 is slided to an optimum position in X and Y directions in the state, where the metallic cylinder 20 is brought into contact with the end part of the receptacle 14, to adjust the position X and Y directions. Parts marked with black triangles are welded along circles by a laser when the maximum coupling efficiency is obtained. Thus, the secular change of the adhesive strength, the occurrence of flux, etc. are prevented.

Title: Fluidic type variable displacement turbocharger
Inventor: YAMAZAKI YOICHI
IPC: F02B39/00
Filed: 1987-06-09
Abstract: PURPOSE:To secure such a variable displacement turbocharger that is low cost and high performance by installing a fixed type swirl generating device which gives such a rotational swirl as getting away from a turbine rotor in and around an outlet to a nozzle part. CONSTITUTION:At time of low engine speed, an expansion ratio before and behind a throat part 7 or an inlet of a scroll chamber 3 is small as well as a turning pitch of a swirl locus D1 of the gas generated at a fixed type swirl generating device (helical passage 6) is small. A speed component in a direction of getting away from a turbine rotor 5 is large and thereby it becomes like the swirl locus E1 crushed in a radial outward direction in a nozzle part 2. At time of high engine speed, a gas swirl locus D2 is large in its turning pitch, whereby such an effect as crushing a flow of gas in the radical outward direction inside the nozzle part 2 becomes smaller so that it becomes like a swirl locus E2.

IPC: G05D3/00
Filed: 1989-06-05
Abstract: PURPOSE:To obtain a compact 6-axial attitude controller by using a movable coil block produced by unifying 8 square movable coils which are set in a 3-dimensional magnetic field formed by 8 cubic permanent magnets which are magnetized in the diagonal direction. CONSTITUTION:The 8 cubic permanent magnets 1 magnetized in the diagnonal direction are arranged so that their magnetizing directions are set radially to each quadrant of the 3-dimensional coordinates. At the same time, 8 square movable coils 2a - 2h are put into the gaps formed among those magnets 1. Then these coils 2a - 2h are unified into a movable coil block 3. a control means 5 performs the feedback control to the currents flowing to the coils 2a - 2h based on the outputs of the position sensors 4a - 4f. As a result, the compliance control is attained to the posture of the block 3 with 6 freedom degrees. Thus it is possible to decrease the number of permanent magnets and to obtain a compact 6-axial attitude controller owing to the absence of ant cylindrical movable matter.

Title: Pellicle
Inventor: KAMINO SATOSHI
IPC: G03F1/62
Filed: 1991-05-17
Abstract: PURPOSE:To prevent foreign matters like dust from penetrating the pattern face of a reticle by forming a groove in the longitudinal direction on the surface of a supporting frame brought into contact with an adhesive layer. CONSTITUTION:Since a groove 10 is provided in the longitudinal direction on the surface where an adhesive layer 8 will be formed of the pellicle, leak is prevented from occuring between the adhesive layer 8 and a pellicle supporting frame 2 when the pellicle is stuck to a reticle 6.

Title: Signal transmission level setting device
Inventor: ARITOMI MAKOTO
IPC: H04M11/00
Filed: 1989-06-05
Abstract: PURPOSE:To prevent a reception error by keeping a reception level at a signal receiving end at a reference level or below at all time. CONSTITUTION:The device consists of a level adjustment means 2 converting a modulation signal into a prescribed level and sending the result to a signal transmission line and a level designation means 6 designating a signal transmission level to set a reception level of an opposite device to a reference level or below to the level adjustment means 2 in response to a detection output of a level detection means 4. Thus, the level of a sending end of the signal transmission line is detected to detect a level in response to the transmission loss of the signal transmission line and it is possible to set the reception level to the reference level or below at all time by selecting a level matching the detected level to the reference level or below. Thus, the reception error is prevented.

Title: Liquid crystal display element
Inventor: HARADA TAKAMASA
IPC: G02F1/141
Filed: 1984-07-10
Abstract: PURPOSE:To make easy an orientation treatment and to permit mass production by subjecting one of two sheets of substrates to a uniaxial orientation treatment and the other to a random horizontal orientation treatment. CONSTITUTION:Liquid crystal molecules 2 are horizontally stuck randomly to the film 4 subjected to the randam horizontal orientation treatment without directivity. The molecules 2 are horizontally fixed in one direction to the uniaxially oriented film 3. The molecules 2 do not move on the film 3 and the molecules 2 which are restricted in the random horizontal direction do not move either. The uniaxially oriented region regulates the arranging direction of the molecules so that a chiral smectic liquid crystal forms a uniform domain and the random horizontally oriented region makes the boundary with the domain growing successively by receiving the influence of the uniaxially oriented region into the free boundary face. The molecules 2 grown from the film 3 exist therefore in the stable position without being forced and the position thereof exists on the intersected line of the virtual cone and the central plane.

Title: Hydrogen engine
Inventor: FURUHAMA SHIYOUICHI
IPC: F02B75/02
Filed: 1980-10-14
Abstract: PURPOSE: To enable the reduction of NO x , the prevention of excessively early ignition at the time of high load and the suppression of knocking in a hydrogen engine of the type ejecting hydrogen of fuel into a cylinder by injecting the hydrogen in the state lower than 0°C.  
     CONSTITUTION: A hydrogen engine is, for example, constructed in two cycle, and has a piston 4 reciprocating in a cylinder 3 having a scavenging hole 1 and an exhaust hole 2, a hydrogen injecting valve 5 interlocked with the piston 4 and an ignition plug 6. The temperature of the hydrogen injected from the valve 5 into the cylinder 3 is lowered to lower than 0°C and is then supplied thereto. Thus, the temperature in the combustion chamber is lowered to reduce NO x . Further, excessively early ignition at high load time can be effectively prevented by cooling the overheated part in the combustion chamber. Even if the compression ratio is increased higher than normal state, knocking is suppressed to improve the thermal effeciency.
