Title: Buried-type semiconductor laser
Inventor: KUSUKI TOSHIHIRO
IPC: H01S5/00
Filed: 1986-02-07
Abstract: PURPOSE:To improve the current stopping function of a layer buried in a substrate by a method wherein a laminate of two types of semiconductor layers, with their lattice constants larger or smaller than that of the substrate, are alternately piled one upon the other and contained in the buried layer, and the two types are different from each other in energy gap. CONSTITUTION:The energy band of a laminate 8 built of a plurality of laminations is shown in the figure. With the InGaP energy gap being larger than that of InAsP, a potential well (a) is created in an InAsP layer 8b, and the potential well (a) arrests electrons 10 coming out of a substrate 1, which reduces the direct current amplification factor Hfe of a transistor. Further, with the InGaP energy gap being larger than that of InP, the threshold voltage of a forward direction P-N junction formed between an N-type InP substrate 1 and P-type layer 8a is larger than that in a conventional design, which results in a decrease in a current 1b. The decrease in the direct current amplification factor Hfe and current 1b results in a current stopping function of a buried layer 9 that is more powerful than that in a conventional design, which greatly reduces a reactive current not useful for laser emission for the attainment of a higher emission efficiency.

Title: Orientational radiotherapy equipment
Inventor: FURUBIKI TAKAAKI
IPC: G21K5/00
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To correct the deviation of radiation from the focus part due to the rotation of a gantry, etc., and to drastically reduce the number of correct value. SOLUTION: The deviation of radiation from the focus part due to the rotation of gantry or treatment bed is corrected by controlling an orienting collimator 19 provided at the gantry for changing the position to be irradiated with the radiation emitted from a radiation head. Namely, the 1st correct value for correcting the position deviation of radiation from an isocenter caused by the rotation of the gantry is stored in a 1st memory 71 corresponding to the rotating angle of the gantry, and the position deviation of the treatment bed from the isocenter caused by the rotation of the treatment bed is stored in a 2nd memory 76 corresponding to the rotating angle of the treatment bed.  While defining the position deviation quantity read out of the 2nd memory 76 corresponding to the current treatment bed rotating angle as a constant and defining a gantry rotating angle θ as a parameter, an arithmetic circuit 78 operates a 2nd correct value so as to irradiate the diseased part deviating the position from the isocenter with the radiation. Then, based on the 1st and 2nd correct values, the static collimator 19 is controlled.

Title: Low leakage magnetic flux type speaker
Inventor: NUMA KATSUYA
IPC: H04R9/02
Filed: 1979-03-07
Abstract: PURPOSE:To reduce the leakage magnetic flux, by connecting in parallel with each magnet constituting the magnetic circuit through the provision of two magnetic circuits. CONSTITUTION:The first magnetic circuit is formed with the first magnet 20, bottom plate 22 and top plate 23 and magnetic flux is produced at the gap 24. The second magnetic circuit is formed with the second magnet 25, shield cover 26, top plate 23 and bottom plate 22 and magnetic flux is produced at the air gap 24. Since the first magnet 20 and second magnet 25 are connected parallelly, the magnetic flux from the respective magnet is added in the air gap 24. Since the shield cover 26 and the top plate 23 are of the same polarity and have no air gap on the way, the leakage magnetic flux is hardly taken place. Accordingly, the speaker with low loss and good efficiency can be obtained.

Abstract: PURPOSE:To keep always high rate of purification in controlling air-fuel ratio in an internal-combustion engine provided with three component catalyzer by setting only a low intake air amount region having at least a predetermined exhaust temperature and small emission amount to an atmosphere of lean air-fuel ratio.

Title: Amplifier
Inventor: ICHINOHE EISUKE
IPC: H03F3/16
Filed: 1982-02-19
Abstract: PURPOSE:To prevent the generation of offset voltage due to each MOST (MOS transistor), by having coincident working characteristics of feedback resistance between positive and negative cycles of an input signal. CONSTITUTION:The characteristics of p channel MOST8 are set coincident with thoes of an n channel MOST7 between positive and negative cycles of an input signal. As a result, the working characteristics of feedback resistance are coincident between the positive and negative cycles of the input signal. This coincidence is attained by obtaining the same mutual conductance between p and n channel MOSTs. In case an AC input vi is added to the DC bias voltage Vi at an input terminal 5 by capacitive coupling, an AC -Avi is added to a DC component Vi for the output voltage at an output terminal 16 as long as an AC amplification factor -A of an inverter 4 is linearly amplified. Therefore a current flows toward the terminal 6 from the terminal 5 via each MOST in terms of the positive half cycle of an AC input. Thus the terminals 5 and 6 function as sources.

Title: Load metal wheel for stringing cable
Inventor: ISHIKAWA KOICHI
IPC: H02G1/02
Filed: 1995-01-20
Abstract: PURPOSE: To absorb slack in a cable by supporting a guide rail on a fixed object, installing a metal wheel roller on a frame that can be slid on the guide rail upward and downward, and imposing load on the cable with the force created when the frame containing the metal wheel roller drops by gravity. CONSTITUTION: When everything is ready, a winch 66 is activated to pull a cable 5, which is let out of a bobbin 61. When the cable 5 is pulled as mentioned above, the frame 4 of a load metal wheel 1 moves upward until it reaches the uppermost position of the guide groove 9 in a guide rail 3. Then pulling the cable 5 is stopped. Since the frame 4 of the load metal wheel 1 is provided with a weight 49 of a specified weight, the frame 4 drops by gravity. This keeps the cable 5 taut and prevents it from slacking, which avoids interference with traffic when a cable is strung across a road.
