Title: Semiconductor light-emitting element and its manufacture
Inventor: OYAMA SHOICHI
IPC: H01L33/14
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To improve directivity by making longer a distance between a surface exposed from a current bottlenecking hole in a substrate and an active layer at the end portion at the substrate side of the current bottlenecking hole than the inner portion of the current bottlenecking hole, thereby making the distribution of the light- emitting intensity uniform and preventing the light leakage sideward. SOLUTION: An n-type current bottlenecking layer 29 is grown on a semiconductor substrate 28, and a current bottlenecking hole 30 is formed in the current bottlenecking layer 29. By doing this, the surface 31 exposed from the current bottlenecking hole 30 of the substrate 28 is located substantially within a plane which contains a contact surface with the substrate 28 of the current bottlenecking layer 29. In other words, the level difference D11 between the plane 31 and the contact surface 39 is zero or almost zero, for example, it is 0.1 to 0.3 μm, and the plane 31 is slightly lower than the contact surface 39.  Thus, the distance L11 between the active layer 33 and the end portion 40 at the side of a substrate 28 of the current bottlenecking surface 30 is formed longer than distances L12, L13 between the active layer 33 and each position 41, 42 of a portion closer to the inner side of the current bottlenecking hole 30.

Title: Automatic bobbin thread supplier
Inventor: SHINOZUKA HISANOBU
IPC: D05B59/00
Filed: 1995-07-13
Abstract: PURPOSE: To prevent the occurrence of failures due to thread hooking or thread cutting defects and to improve reliability. CONSTITUTION: Bobbin thread 150 from a bobbin thread supply source 200 is wound around a bobbin 7 by the bobbin rotation of a bobbin thread winding device 162 and the bobbin thread 150 wound around the bobbin 7 between the bobbin case 2 and the bobbin thread supply source 200 is cut by a thread cutting device. Then, the bobbin thread 150 wound around the bobbin 7 after cutting the thread is displaced by bobbin thread displacing means 160 and 161, and at the time, the presence/absence of displacement are detected by bobbin thread detection means 60, 145, 144 and 146.  Corresponding to the presence/absence of the displacement, at least one of the normal/defective condition of thread cutting and the normal/defective condition of thread hooking is judged by a judgement means 255, and in the case of judging the defect, this supplier is stopped for instance and the occurrence of the failures due to the thread cutting defect or the thread hooking defect is prevented.

Title: Variable gain amplification device
Inventor: IKEDA CHIKAO
IPC: H03G3/12
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To lower the cost and to reduce noise to the output as to the variable gain amplification device which has its gain switched to different values when an input bias voltage is inputted and when the signal having an input signal superposed on the input bias voltage is inputted. SOLUTION: The gain of the whole variable gain amplification device is 0dB when switches 6 and 10 is turned on and a gain determined by the capacity ratio of capacitors 4 and 13 when the switches 6 and 10 is turned off. The gain that a differential amplifier 14 takes charge of is determined by the capacity ratio of capacitors 4 and 5 and total negative feedback operates so that an operational amplifier 11 takes charge of the remaining gain. The total gain of the differential amplifier and operational amplifier is smaller than that when two operational amplifies are use. Consequently, the capacity of a capacitor required to secure the phase margin for preventing oscillation may be small and the manufacture cost is lowered.  When the switch 6 is turned on first, noise at off time is amplified substantially only by the differential amplifier, so a shift in output level due to the noise is reduced.

Title: Motional feedback electro-accustic transducer
Inventor: WADA YASUMITSU
IPC: H04R9/04
Filed: 1981-12-16
Abstract: PURPOSE:To suppress the power coefficient of a detection coil during a large amplitude, by defining the relation among the turn width of a driving coil, the set value of the magnetic gap of a magnetic circuit and the turn width of a detecting coil respectively. CONSTITUTION:The turn width of a detecting coil 4 is set to that the absolute value (b) of the difference between the turn width of a detecting coil 4 and the set value of the magnetic gap 1A of a magnetic circuit 1 is larger than the absolute value (a) of the difference between the set value of the gap 1A and the turn width of a driving coil 3. The distribution is constant for the magnetic density of the transmitted magnetic flux within the set width of the gap 1A and is decreased outside the set value. Therefore the power coefficient is constant to the coil 3 up to the difference (a) between the turn width of the coil 3 and the set value of the gap 1A and then decreases when it exceeds the difference (a). That is, the amplitude margin of the coil 3 is equal to (a). In this case, the amplitude margin of the coil 4 is equal to the difference between the gap 1A and the turn width of the coil 4, that is, b<a is obtained. Thus the power coefficient of the coil 4 does not change up to (b) although the power coefficient of the coil 3 varies.

Abstract: PROBLEM TO BE SOLVED: To intuitively understand an obstruction interrupting radio wave by detecting the position of a satellite which can be received or cannot be received and indicating it in such a manner that it may be discriminating easily. SOLUTION: An advancing-direction operation part 12 detects the radio wave doppler shift of every satellite from the output signals of a GPS reception part 11 which receives radio waves of every satellite through an antenna 10 and it operates the advancing direction P of a mobile body, then it sends the direction to an indication control part 14. In addition, a satellite information detection part 13 detects the position and reception status of a satellite which can be received, according to the output signal 11. The control part 14 finds relative angles between the positions P and respective satellites in order to prepare a newly corrected data for indication. The indication part 15 draws the sky position of the respective satellites by using the data and indicates it together with the reception status.  Then, in case where there is no satellite that can be received, the value just before the reception level becomes lower among the results that the detection part 13 stores every time is adopted so as to find out the position of a satellite which cannot be received and draw it. At this time, it is indicated by different colors, etc., so that it may be easily discriminated, thereby understanding intuitively an abstruction interrupting the radio wave from the satellite.
