Title: Manufacture of semiconductor device
Inventor: NISHIYAMA AKIO
IPC: H01L21/26
Filed: 1989-08-28
Abstract: PURPOSE:To manufacture a semiconductor device of even characteristics and less thermal stress by a method wherein multiple members comprising multiple different materials arranged on a semiconductor substrate are irradiated with incoherent beams with the maximum intensity in the wavelength having almost equal photoabsorption coefficient of the said mutually different materials. CONSTITUTION:Multiple members 12, 18, 19 comprising mutually different materials and arranged on a semiconductor substrate 11 are irradiated with incoherent beams with the maximum intensity in the wavelength having almost equal photoabsorption coefficient of the mutually different materials so as to heat the semiconductor substrates 11. Since the irradiating beams are incoherent beams, even if light-transmitting material is contained in the mutually different materials comprising the multiple members 12, 18, 19, the interference effect is minor. Accordingly, even if the transparent material is used in various thicknesses, the unevenness in heating the surface of the semiconductor substrate 11 due to the difference in the interference effects is negligible. Therefore, a semiconductor device of even characteristics such as sheet resistance value, etc., and less thermal stress can be manufactured.

Title: Ac voltage controller
Inventor: MURAMATSU KAZUHARU
IPC: H02P23/07
Filed: 1990-08-24
Abstract: PURPOSE:To make smooth the current waveform and to suppress higher harmonic component by providing an interlock circuit for turning each flywheel transistor ON with a predetermined forward voltage and for limiting the flywheel transistor upon turn ON of a main switching element. CONSTITUTION:Upon turn ON of a main switching element TRm within positive half period of a power supply 10, a transistor TR4 in an interlock circuit is turned ON. Consequently, the bases of transistors TR1, TR2 have a voltage equal to the emitter voltage and thereby the transistors TR1, TR2 are turned OFF. In other words, a current flows through a diode D1, the main switching element TRm and a diode D2 into a load 12. Upon turn OFF of the main switching element TRm, the TR4 is turned OFF. The TR3 is turned OFF continuously during positive half period of the power supply 10. Consequently, the bases of TR1, TR2 are interrupted from the emitter and the TR1, TR2 are turned ON upon application of a forward voltage.

Title: Apparatus for measuring azimuth
Inventor: KOJIMA MAKOTO
IPC: G01S3/22
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To make reducible a measuring error and to make automatically measurable radio wave incoming direction by inverting a video signal based on a subtracted beam and multiplying a waveform obtained by adding a voltage of a peak value of the signal to the inverted signal by a video signal based on a subtracted beam by a multiplying means. SOLUTION: Envelopes of first and second signals are detected to generate first and second video signals. A subtracted beam b after the envelope detections is subtracted from its peak value. A waveform c obtained by the subtraction is multiplied by an added beam a after the envelope detections to obtain a waveform d. Then, the waveform d is identified by a threshold voltage Vo2 to decide a radio wave arrival bearing. Thus, a sharp peak can be obtained in the bearing. Even in the case of measuring an angle by hand while observing the waveform, the angle can be measured at a small error. Further, since the angle detecting point is appeared not at a null point but in a positive direction in a sharp waveform, an identifying threshold voltage Vo2 can be largely set, thereby improving the accuracy of an angle measurement value.

Title: Automatic focusing device
Inventor: MATSUMURA KENICHI
IPC: G02B7/28
Filed: 1982-12-16
Abstract: PURPOSE:To perform accurate automatic focusing even when an image is low in contrast by detecting the variable density level of an interference fringe and regarding the position of a variable density level larger than a specific value as a focusing position. CONSTITUTION:A sample 20 is moved as shown by an arrow A to form the interference fringe. Variation in the variable density level of this interference fringe is detected through a slit 27. A reference light mirror 24 is so positioned previously that the variable density level output value of the interference fringe is maximum when the sample is in focus; and the value of the detection signal of the interference fringe when the sample is within the depth-of-focus range of an objective 23 is predetermined and the sample 20 is set where the variable density level of the interference fringe is larger than the value, attaining automatic focusing. Consequently, the precision of the focusing is irrelevant to the contrast of a real image of the sample, so the automatic focusing is accurate even when the image has low contrast.

Filed: 1997-08-18
Abstract: PROBLEM TO BE SOLVED: To improve a contact of a heating drum and of an endless belt with a heat developed photosensitive material, by making up the endless belt of a material having air permeability. SOLUTION: A heat developed photosensitive material A is conveyed being sandwiched between a heating drum 63 and an endless belt 65, and heated up to about 120 deg.C by a heat source 39 provided in the heating drum 63. The endless belt 65 is made up of a material having very fine open cells. Because of this, most of gas generated at the time of processing the heat developed photosensitive material A is discharged via the very fine open cells. A surface of the heating drum 63 is roughened very finely, and therefore most of gas generated at the time of processing the heat developed photosensitive material A is discharged via very narrow gaps formed between the heat developed photosensitive material A and the heating drum 63.  That is, most of the gas is discharged and prevented from being put between the heat developed photosensitive material A and the endless belt 65, and between the material A and the heating drum 63, and thereby generation of photographic density irregularity is suppressed.

Filed: 1998-08-05
Abstract: PROBLEM TO BE SOLVED: To provide an epitaxial wafer in which a p-type inversion is not generated in a part near the bonding part of a substrate to an n-type clad layer, in which a light fetching face is a p-type layer and whose yield is high and to provide its manufacturing method as well as to provide a light emitting diode. SOLUTION: An n-type GaAlAs clad layer 2, a p-type GaAlAs active layer 3 and a p-type GaAlAs clad layer 4 are formed sequentially on an n-type GaAs substrate 1 by a liquid-phase epitaxial method. At this time, the concentration of C in the n-type GaAlAs clad layer 2 is set at 1.0×1018 cm-3 or lower, and an epitaxial wafer is manufactured sequentially. As a result, the peak concentration of C becomes lower than the concentration of Te near the bonding part of the n-type GaAlAs clad layer 2 to the n-type GaAs substrate 1, and a p-type inversion is not generated near the bonding part. When the epitaxial wafer is used, it is possible to obtain a light emitting diode in which a light fetching face is the p-type GaAlAs layer 3 and whose yield is high.

Inventor: ODATE HITOSHI
IPC: H04B17/40
Filed: 1987-09-07
Abstract: PURPOSE:To measure the quantity of propagation attenuation between a transmission antenna and a reception antenna by using a signal in the course of relaying, by allowing a transmission signal frequency slightly to offset from a reception signal frequency, and detecting a transmission signal component contained in a reception signal. CONSTITUTION:After a signal inputted from the transmission antenna 1 (outgoing line signal) is shifted by a few definite frequency (e.g., 100Hz) by a frequency converter 12, and is amplified by an amplifier 13, it is transmitted as a transmission signal from the transmission antenna 4. When the transmission antenna and the reception antenna are coupled, a ripple equal to the shift quantity is generated in a reception signal envelope, and the magnitude of the ripple is proportional to coupling quantity between the transmission and the reception antenna. A level detector 16 detects the presence and absence of a level for the whole outgoing lines, and monitors a channel being used by a base station. The smallest value of the attenuation quantity among the measured propagation attenuation quantities of respective bands between the transmission and reception antennas is considered to be the propagation attenuation quantity between the transmission and the reception antennas, and at the time of the installation of a radio repeater, a repeating gain is set so as not to exceed said attenuation quantity.

IPC: H02G1/08
Filed: 1988-09-06
Abstract: PURPOSE:To facilitate pulling work of wire by making spiral grooves in the surface of a plastic member and employing a hollow metallic pipe in the central section in order to improve the rigidity. CONSTITUTION:Spiral grooves are made in the outer circumference of a plastic member and a hollow metallic pipe 2 is employed in order to improve the rigidity. By such arrangement, pulling work of wire can be facilitated even when a pull rod enters into stranded power cables or into a gap between the power cable and the inner wall of conduit at a curved section of a conduit laid with a triplex power cable and thereby the pull rod can not be pushed in furthermore nor pulled out easily. This is because the spiral grooves made in the surface of the plastic member promotes insertion of the pull rod along the stranding direction even in case of a stranded triplex cable. Furthermore, the hollow metallic pipe 2 for improving the rigidity enables flexible insertion of the cable corresponding to the curvature of the conduit and prevents folding of the cable.
