Title: Production of aluminum oxide powder
Inventor: HASHIMOTO NOBORU
IPC: C01F7/306
Filed: 1991-10-16
Abstract: PURPOSE:To improve dispersibility by dissolving a polynuclear Al complex and a water-soluble carbon-contg. compd. in water, mixing them and carrying out firing in an N2-contg. reducing atmosphere and heat treatment in an oxidizing atmosphere. CONSTITUTION:One or more kinds of polynuclear Al complexes each having two or more central Al atoms such as basic aluminum chloride, basic aluminum lactate and basic aluminum nitrate and a water-soluble carbon-contg. compd. such as methylcellulose are dissolved in water so as to become W>=1.5 molar ratio of C including C in the complexes to Al, and they are mixed and dried. This dried mixture is fired at 1,300-2,000 deg.C in an N2-contg. reducing atmosphere and the resulting mixture consisting of Al nitride, Al oxynitride and carbon is heat-treated at 500-1,000 deg.C in an oxidizing atmosphere to obtain high purity fine Al2O3 powder of 0.01-1.0mum average particle diameter.

Title: Photointegrated circuit device
Inventor: KIMURA SOICHI
IPC: H01S5/042
Filed: 1988-10-26
Abstract: PURPOSE:To prevent increase of oscillation threshold by making a forbidden band width of P-type InGaAsP layer smaller than that of an InGaAsP layer. CONSTITUTION:In a laser section 19, an InGaAsP layer 6 is an active layer, and made in a double hetero-junction by a P-type In layer 7 and an N-type InP layer 5. A P-type InGaAsP layer 4, an N-type InP layer 3 and a P-type InP layer 2 are formed at both sides of a mesa 55 as a thyristor of PNPN. Here, a forbidden band width of the P-type InGaAsP layer 4 is smaller than that of the InGaAsP layer 6; therefore, light emitted at an active layer is absorbed by the P-type InGaAsP layer 4. Since light emission is also thereby limited to a region on the mesa 55, light confinement is carried out in a transverse direction. Laser oscillation can be realized at a low threshold value in this way.

Title: Semiconductor chip mounting substrate and high- frequency device
Inventor: UDA NAONORI
IPC: H01P5/08
Filed: 1999-09-22
Abstract: PROBLEM TO BE SOLVED: To provide a mounting substrate for facilitating the mounting of a semiconductor chip. SOLUTION: For the substrate for facilitating the mounting of a passive type high-frequency semiconductor chip, a microstrip line 60, a line conversion part 70 for a quarter-wavelength λ/4, to gradually increaese a line width, and a coplanar line 80 continued to that conversion part are formed on a ceramic substrate 50. Then, that couplanar line 80 and the couplanar line of a semiconductor chip 100 to be mounted are connected by a wire 90. Thus, a signal is inputted to the semiconductor chip 100, after an electric field mode is sompletely converted to a coplanar line type on the ceramic substrate 50. Namely, the signal is inputted after the electric field mode is matched completely. Since there is the coplanar line type electric field on the semiconductor chip 100, a vertical electric field is not generated.  Therefore, a high-frequency signal hardly flows to the ground substrate 110. Thus, the number of wires for high-frequency grounding can be reduced, and the semiconductor chip 100 can be mounted easily.

Abstract: PROBLEM TO BE SOLVED: To provide An FM multiplex broadcast receiver by which a same broadcast content is received in an excellent condition by selecting automatically the same content broadcast without being affected by a tentative fluctuation in a radio wave. SOLUTION: A CPU 41 detects frequency list information of broadcast stations of a same content from a received FM multiplex broadcast signal and stores the detected frequency list information to a memory 43. The CPU 41 discriminates whether or not a level of an intermediate frequency signal from an intermediate frequency amplifier detection circuit 15 is within a reference value at every prescribed time, an error counter 47 conducts count processing at every prescribed time and increases/decreases the count when the level of the intermediate frequency signal is deviated from the reference value and clears the counted number when the level of the intermediate frequency signal is within the reference level,  and the CPU 41 selects a substitute frequency signal of a broadcast station of a same content from a prescribed frequency signal based on frequency list information when the count reaches a predetermined specified value.

Abstract: PROBLEM TO BE SOLVED: To absorb eccentricity and an eccentric angle of an upper drum for a lower drum and to control a magnetic head position by controlling an attitude of a drum fixed part based on a distance from the lower drum to a middle drum detected by a magnetic change in magnetic flux flowing between a magnetic response part and a magnetic responsed part. SOLUTION: A rotary drum device 18 detects height displacement from a lower drum part 22 to an upper drum part 21 by an inductance change type sensor 25 to send a detected distance signal S1 to a drum attitude control part 26. Further, a drum motor pulse generator (not shown in figure) sends a motor pulse S2 showing a rotating phase of a scanner loading a magnetic head to the drum attitude control part 26. This control part 26 outputs a control signal S3 controlling the attitude of the upper drum part 21 to the drum fixed part 24 based on the distance signal S1 and the motor pulse S2. Thus, the rotary drum device 18 controls the attitude of the upper drum 21 by that the drum attitude control part 26 controls the attitude of the drum fixed part 24, and rotates the scanner loading the magnetic head in precise rotation locus.

Abstract: PROBLEM TO BE SOLVED: To restrain the protruding length of the rear end of a counter weight from a base carrier to ensure the mount of an additional counter weight on the counter weight. SOLUTION: Additional counter weight mounting bosses 31, 38 are arranged on the upper surface part 28C of a counter weight 28 so as to locate on the rear side from hoisting accessory mounting bosses 34, 35.
