Title: Ferroelectric liquid crystal element
Inventor: OKADA SHINJIRO
IPC: G02F1/141
Filed: 1987-09-18
Abstract: PURPOSE:To dispose a polarizing plate in the more optimum position and to improve contrast by setting the absorption axis of cross nicols at the state of the larger quantity of the transmitted light, of the two stable states while an electric field is not impressed. CONSTITUTION:The quantity IS2 of the transmitted light in the S2 state when the absorption axis of the crossed nicols is set in the average direction of the major axes of the molecules in the S1 state is provided if the two states of the two stable states S1, S2 are not equiv. while the electric field is not impressed. Said quantity is then compared with the quantity IS1 of the transmitted light in the S1 state when the absorption axis of the crossed nicols is set in the average direction of the major axes of the molecules in the S2 state. The absorption axis of the crossed nicols is set at the state of the larger quantity of the transmitted light. The liquid crystal element having the improved contrast is thereby obtd.

Title: Semiconductor light emitting device
Inventor: SUGANO YOSHIYASU
IPC: H01S5/042
Filed: 1986-09-30
Abstract: PURPOSE:To narrow a spectral width in the case of high speed mudulation and ensure high speed, long distance, and high-volume transmission by setting the length of a resonator where waves are guided in the direction of stripes in the region of 400 mum-600 mum. CONSTITUTION:In the case of Fabry-Perot type V-grooved substrate buried (VSB) semiconductor laser where a stripe-like InGaAsP or InGaAs system active layer 4 is buried on an InP substrate 1, its resonator length is set up in the region of 400 mum-600mum. The more the resonator length is extended, the more the lifetime of photon is increased and the smaller is a spectral fluctuation due to a variation of a carrier that is developed with high speed modulation. In other words, the more the resonator length is extended, the more a gain distribution is enlarged in the same way as with an [ oscillation circuit of an electric circuit and as a result, Q of the resonator becomes larger. Such a state of the resonator makes a spectral width narrower and helps ensure high speed, long distance, a high-volume transmission.

Abstract: PURPOSE:To secure the strength and rigidity necessary for the structure and reduce the number of components by providing two planetary gears on the outer periphery so as to be integrally rotated using an eccentric shaft provided integrally with an input shaft as a planetary gear shaft. CONSTITUTION:When rotation is applied to an input shaft 1, an eccentric shaft 12 rotated integrally performs the turning motion using the eccentricity (1) as an arm and transmits the same rotation as the input shaft 1 to an output shaft 6 vie the right planetary gear 3' provided on the outer periphery and an internal gear 7 inscribed and engaged with it. The left planetary gear 3 engaged with a fixed internal gear 5 is revolved in engagement with the fixed internal gear as the eccentric shaft 12 is rotated and transfers the same rotation to the right planetary gear 3' and transfers the rotation to the output shaft 6 via the engagement motion with the internal gear 7. Two kinds of rotating motion are synthesized and transmitted to the output shaft 6 as the true output rotation. The eccentric shaft 12 applied with the large torque can be formed large and strong, and the strength and rigidity can be secured.

Title: Loading device for vessels into container box as in stacks
Inventor: INOUCHI TETSUYA
IPC: B65G59/10
Filed: 1982-12-29
Abstract: PURPOSE:To load vessels neatly in a container box by equipping an elevating frame beside the container box with a vessel receptacle tilting piece, which will protrude inside the box when it rises to a specific level and return at the sunk position, and then only by feeding the vessels to be stacked one after another into the container box. CONSTITUTION:When vessels S to be loaded stacking in a container box 2 are fed in the box, an elevating frame is raised to a position near a cast-in hole 2A to allow protrusion of a tilting piece 24 inside the box 2, so that the vessels S can be well received. When thereafter the vessels S are further fed while the frame is depressed, they are stacked up in the box 2 one over another. When the lowermost vessel S sinks down to a tekeout hole 2A, said tilting piece 24 comes in contact with a below-situated working member 21 and retracts out of the box 2 while taking vertical position, so that it loses support by the piece 24 and thus accommodated in the box 2. According to this arrangement, vessels S do not drop by their own weight, so that those stacked up one over another are not separated.

Title: Semiconductor laser amplifier
Inventor: NAMEGAYA TAKESHI
IPC: H01S5/00
Filed: 1988-09-19
Abstract: PURPOSE:To obtain a sufficient amplification gain with a short device length and change the taking-out direction of a light in a substrate surface and facilitate a high integrity by a method wherein an angle formed by a waveguide and an end surface is so selected as to make the incident angle of a laser beam propagated in the waveguide against the end surface larger than a critical angle. CONSTITUTION:An n-type InP first cladding layer 2, an InGaAsP active layer 3 and P-type InP second cladding layer 4 are successively built up on an n-type InP semiconductor substrate 1. The thicknesses of the parts of the second cladding layer corresponding to waveguide are increased a little. With this construction, a light confining cladding part 8 is formed. The waveguide is bent at both the end surfaces 9 and 10 and formed into a zig-zag shape. Angles formed by the waveguides and the end surfaces 9 and 10 are so selected as to make the incident angle of an incident laser beam against the end surfaces 9 and 10 larger than a critical angle. Therefore, the incident laser beam is totally reflected by the end surface 10 which functions as a totally reflective surface 11 and guided into the other waveguide. Further, the laser beam is totally reflected by the end surface 9 and taken out from the end surface 10 through a non-reflective coating film.

Title: Electromagnetic relay
Inventor: KURAUSU RIYUUNEBURUGAA
IPC: H01H50/02
Filed: 1988-09-21
Abstract: PURPOSE: To allow the switching of a high voltage by producing a compression force on a second end of a leaf spring by exciting a coil to attract the armature, by controlling the deflection of a middle portion of a spring, and by moving a movable contact toward an opposed contact element. CONSTITUTION: When a coil is not excited, a contact spring 71 is free. Moreover, while an armature 4 is pressed against a stopper 16 of a base body to reach its stop position, the contact spring 71 is straightened. At this position, a contact 72 is combined with a contact 51 to form a normally closed contact. When the coil is so excited that the armature 4 is attracted to a yoke leg 33, a contact spring blade 71 is pushed by the movement of the armature 4, then causing distortion to close a normally opened contact between a contact pieces 73 and 61. This enables the switching even if a high voltage is applied.

IPC: H02J3/38
Filed: 1994-09-29
Abstract: PURPOSE: To simplify the entire system construction of a power unit which is controlled by a constant current and performs parallel redundant operation. CONSTITUTION: The current detection signals of shunt resistances 15, 15A and 15B are added together by an addition circuit 21 and supplied to each voltage variable terminal TRM as the common variable command voltage. The output currents I1, I2 and I3 of the power main bodies 11, 11A and 11B are kept at a constant level by the common variable command voltage. Thereby, the large and expensive resistances 15, 15A and 15B are not necessary because they are provided in bodies 11, 11A and 11B respectively. Furthermore, it is enough just to connect a shunt resistance to a power main body 11C that is newly added.

Abstract: PROBLEM TO BE SOLVED: To simplify an air pipeline by connecting an intake pipeline to an air chamber formed to a radiator support frame for an engine. SOLUTION: The channel-shaped sectional opening section of a radiator frame 34 is installed integrally or to a main frame 10a by welding, both ends in the longitudinal direction of the radiator support frame 34 are closed by plates 34a, 34b, and an air chamber 35 in a closed space is formed into the radiator support frame 34. The intake system 22 introducing the outside air induced from an air cleaner 18 into an intake manifold opening 8d for an engine 8 through an intake pipeline 20, the air chamber 35 and a suction pipeline 21 is formed.
