Title: Semiconductor light-emitting element
Inventor: OBA YASUO
IPC: H01S5/00
Filed: 1994-03-09
Abstract: PURPOSE:To obtain a semiconductor light-emitting element which realizes a good heterojunction structure and whose high brightness is achieved by a method wherein a compound semiconductor material which is lattice-matched with a GaN-based material and whose band gap is narrower than that of GaN is used for a light-emitting layer. CONSTITUTION:In a semiconductor element which uses a group III-V material such as a GaN-based material or the like, a compound semiconductor which is composed of group II atoms A, group IV atoms B, group III atoms C and nitrogen atoms N and which is expressed by a composition formula of AxBxCyN2x+y (where o<x <=1 and 0<=y<1) is used for a light-emitting layer 13. That is to say, a part or the whole of the group III atoms for a III-V compound semiconductor is replaced by the group II atoms and the group IV atoms. Thereby, a double heterojunction structure which is lattice-matched with the GaN-based material and which is good can be relaized, and a light-emitting element in a visible region can be relaized. In addition, since a light-emitting operation between bands by the double heterojunction structure is utilized and the double heterojunction structure is of good quality, the high brightness of the semiconductor light-emitting element can be achieved.

Title: Manufacturing of bipolar integrated circuit
Inventor: SHINOZAKI SATOSHI
IPC: H01L29/08
Filed: 1980-03-26
Abstract: PURPOSE:To provide a constant rate of increase of current and a highly improved performance of operation of bipolar IC by a method wherein an emitter width of another transistor is uniformly made to a minimum emitter width to be formed. CONSTITUTION:When an emitter of a bipolar transistor is to be performed, hFE is decreased in response to an emitter width less than a certain value. A value of width in which a decreased emitter width is made is not limited in general in response to the kind of emitter dispersion source, and 4mum or less is found at a dispersion of As. Thus, when IC containing a plurality of bipolar transistors having emitter width in which hFE is varied, an emitter width of another transistor is unified to a minimum emitter width, hFE of each of the component elements is made to be constant, an allowable range of hFE of IC is reduced and a performance of operation is excessively improved.

Title: Horizontally positioning method utilizing communicating pipe and setting-out method and apparatus
Inventor: IZUMITANI TAKESHI
IPC: B25H7/04
Filed: 1992-01-29
Abstract: PURPOSE:To enable horizontally positioning quickly and accurately by setting a water level at an open end of a hose filled with a liquid as reference surface to measure the height of a level at a closed end by an output pressure of a pressure sensor with the other end thereof closed by the sensor. CONSTITUTION:A hose 8 composing a communicating pipe is filled with a liquid 10 such as water and a closed end 8b thereof is closed by covering a head face with a pressure sensor 9 to close. The open end 8a of the hole 8 is fixed and the closed end 8b is displaced in the vertical way with the a water level as reference surface 11. If so, the sensor 9 notifies a positive pressure at a position 12 lower in the head at the closed end 8b than the reference surface 11, a negative pressure at the position higher than the reference surface and a zero in pressure at a water pillar height 14 the same as the reference surface. Thus, the height can be learned with respect to the height of the reference surface 11 from the numeral pressure notified. In simple utilization, a zero notified level is determined regarding the head face level at the closed end 8b as setting-out point and a leveling is performed at the level obtained. The notification is instantaneous and is very sensitive to changes in the pressure of the sensor 9 thereby enabling accurate leveling.

Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To improve the cooling effect of a cooling room for storing powdery materials in a cooled state by circulating cold water pumped up by an impellar attached to an agitation shaft of an aditator for agitating water in an water tank through an water distribution pipe spread on the inwall surface of the cooling room for storing raw material boxes. SOLUTION: Each raw material box 6 individually stores a raw material for severage in each sort. The water tank 8 cools and stores city water. The agitator 20 agitates water in the water tank 8 by an agitating blade 21 to execute heat exchange and draws out cold water pumped up by the impellar 23 to the external by pipe connection. The water distribution pipe 40 is attached to the inwall and cold water of the tank 8 pumped up by the impellar 23 of the agitator 20 is circulated through the pipe 40 to cool the inside of the room 30. Since water in the tank 8 is pumped up by the impellar 23 attached to the agitation shaft 22 of the agitator 20, it makes unnecessary to newly prepare a pump or the like for circulating cold water and constitution can be simplified.

Title: Directional ground relay
Inventor: MIYANO TADASHI
IPC: H02H3/38
Filed: 1988-02-22
Abstract: PURPOSE:To achieve stable operation, by varying the operational phase angle as the time elapses after occurrence of ground fault. CONSTITUTION:Upon occurrence of V0, I0 due to fault in feeder lines, they are detected through level detectors 1, 2 which produce outputs. An AND gate 3 makes AND of V0 and I0, which is then integrated through an integrator 4. A sensitivity determining section 10 shifts the maximum sensitivity angle phi1 in delaying direction as the time elapses after occurrence of ground fault and finally fixes it at a position of 10 deg.+ or -90 deg.. An operational phase judging section 5 judges whether the phase relation of I0 with respect to V0 is within phi+ or -90 deg., and if it is within the range, an AND gate 6 makes logical product of the outputs from the level detectors 1, 2 and outputs the logical product as a protective operation signal.
