Title: Superluminescent diode
Inventor: KASHIMA YASUMASA
IPC: H01S5/223
Filed: 1988-11-30
Abstract: PURPOSE:To obtain a superluminescent diode of high quality easily by a means with high reproducibility by forming the diode in a groove structure, and providing a light diffusing face in contact obliquely with the rear end face of an active layer buried in the groove. CONSTITUTION:An N-type InP current blocking layer 12 and a P-type InP current blocking layer 13 are sequentially formed on a P-type InP semiconductor substrate 11, and a V-shaped groove 14 is formed over a predetermined length on the layer 13. The groove 14 has a depth arriving at the substrate 11 through the layer 12. A P-type InGaAsP active layer 16 is buried through a P-type InP clad layer 15 in the groove 14 in its longitudinal direction. A light diffusing face 17 is formed at the longitudinal rear of the groove 14. The face 17 is formed of the substrate 11 in contact with the rear end face of the groove 14 and the layers 12, 13, and the contact facer is brought into contact with the layer 16 as an oblique face. That is, the face 17 is inclined with respect to the propagation direction of the light emitted from the layer 16, and the light is diffused on the face 17.

Title: Peripheral edge seaming tool of lagging elbow
Inventor: HATAKEYAMA TOSHIO
IPC: B21D39/02
Filed: 1988-11-30
Abstract: PURPOSE:To eliminate the possibility that a peripheral edge is detached from a a groove of a pressure roller, to increase the work speed, and to improve work efficiency by placing a guide roller in front of the pressure roller and leading the peripheral edge thereby. CONSTITUTION:The lower peripheral edge of a metallic plate 33b and the upper peripheral edge of a metallic plate 33a are superposed to each other, and thereafter, they are led to a groove 15 between a pair of pressure rollers 10a, 10b. In this case, a bent part 35d of the lower peripheral edge comes into contact with the outside peripheral surface of the upper guide roller 26a and guided to the groove 15 of a pressure roller 10. Also, a bent part 35u of the upper peripheral edge also comes into contact with the outside peripheral surface of the lower guide roller 26b and guided, and led to the groove 15 of the pressure roller 10. Subsequently, a pair of pressure rollers 10a, 10b rotate in the opposite direction so as to roll in a metallic plate 33 by rotational force of shafts 12a, 12b, and the peripheral edges are tightened, allowed to adhere closely and connected. In this case, a projecting part 18 of the upper pressure roller 10a and a small diameter part 21 of the lower roller 10b work on each other, and a skirt part 37 of the lower peripheral edge is pushed and bent downward. In such a way, a metallic covering running along a curved part of a piping can be manufactured.

Title: Second hand stopping mechanism of clock unit
Inventor: OTA MASAKI
IPC: G04B27/00
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To stop the drive of the second hand without damaging a gear by shifting the center of a magnetic pole piece of a rotor from the position of a stator in the axial direction by a pressing piece near the rotor. SOLUTION: When an electric current is carried to a coil 21, the center of a magnetic pole piece 15 attracts a rotor 10 to be close to a stator 23 with the magnetic force of the stator 23. Thus, the position of the rotor 10 is stabilized and rotated 180 deg. by 180 deg. every time the magnetic pole 23 of the stator 23 is switched by a motor driving pulse to drive the second hand through a gear train. When a pressing piece 25 near the rotor 10 is moved in the direction of the rotating shaft of the rotor 10 to be close to the rotor shaft, the inclined surface of the pressing piece 25 comes into contact with a magnetic pole support part 13 of the rotor 10 side surface part. If the pressing piece 25 is further pushed in, the tip 26 of the pressing piece 25 comes into contact with the upper surface of the support part 13, and the rotor 10 is pushed down so that the tip of a bearing part 35 comes into contact with the support part 13. Thus, the rotation of the rotor 10, the turning torque of which is decreased, is inhibited by contact resistance of the tip 26, so that the second hand can be stopped without damaging the gear.

IPC: B60L9/18
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To make it possible to curb the occurrence of slip for maintaining an acceleration capability by reducing a torque according to a slip amount in such a manner that the accelerating force of an electric car is close to a maximum value of adhesion.

Title: Solar radiation sensor for car air conditioner
Inventor: KODAMA SHUICHI
IPC: B60H1/00
Filed: 1992-11-16
Abstract: PURPOSE:To facilitate production and simply allow a small change of the output characteristic by roughening part of the surface of the photo-detector side face as compared with the light source side face of a solar radiation sensor lens. CONSTITUTION:A photo-detector 1 is provided with at least one light detecting element 2, detects the solar radiation quantity received by the element 2, and outputs the signal in response to the intensity of the solar radiation quantity. The signal is fed to the controller of an air conditioner and the air conditioner is controlled in consideration of the intensity of the solar radiation quantity. A lens 3 is constituted of a light source side face 4 and a photo-detector side face 5. When the surface finishing of the lens 3 is rough, a phenomenon occurs that the transmitted light causes irregular reflection on the surface of the lens 3. If irregular reflection occurs on the plane section 5b of the side face 5, the quantity of the light transmitted through the plane section 5b to reach the element 2 is reduced, and the output value is reduced. When the plane section 5b is wholly or partially roughened, the output value can be reduced.

IPC: H04Q3/00
Filed: 1996-11-05
Abstract: PROBLEM TO BE SOLVED: To identify a packet header and data at any time by burst-transferring both the header and the data to a header buffer. SOLUTION: Components 20-36 of an NIC 12 are cooperated to transfer data between a host computer 48 and other computer in a network through a plurality of channels assigned dynamically in a plurality of band width groups. After transfer of each burst to a header/data buffer, two stages of the method are adopted to discriminate proper update to a related control pointer and at least to one control counter. In the case of discriminating proper update, whether the NIC 12 applies burst-transfer of the header, or burst-transfer of the data, whether the NIC 12 transits from the header burst-transfer to the data burst-transfer is taken into account. Moreover, whether a packet is processed as an exception or not, that is, whether or not the header and the data are not distinguished is taken into account.
