Title: Ultrasonic distance measuring instrument
Inventor: MURAMATSU KATSUHISA
IPC: G01B17/00
Filed: 1994-11-14
Abstract: PURPOSE: To measure the distance to an object without receiving any influence of the amplitude of received signals by outputting transmitting signals containing a phase modulating point after converting the signals into ultrasonic waves, by finding the distance based on the time from the transmission of the transmitting signals to the reception of the phase modulating point of the received signals composed of reflected waves, and then, by changing the amplification degree of a reception circuit in accordance with the amplitude of the received signals. CONSTITUTION: A transmitting circuit section 12 outputs transmitting signals (a) containing a phase modulating point (x) and an ultrasonic transducer 86 converts the signals (a) into ultrasonic waves U. The waves U are reflected by an object 84 to be measured and return to the transducer 86 and the transducer 86 converts the waves U into received signals (b) and supplies the signals (b) to a reception circuit section 14. A time measuring section 16 measures the time (t) from the outputting timing of the signals (a) from the section 12 to the inputting timing of the point (x) of the signals (b) to the section 14. A distance calculating section 18 finds the distance D between the transducer 86 and the object D from D=(t×v)/2 (where, v is the acoustic velocity).  A variable gain adjusting section 191 adjusts the amplification degree A of the section 14 in accordance with the amplitude of the signals (b). Therefore, the influence of the magnitude of the amplitude of the signal (b) can be eliminated.

IPC: C21D8/12
Filed: 1992-10-02
Abstract: PURPOSE:To produce a thin high-silicon grain oriented silicon steel sheet by performing warm rolling at a temp. right under the recrystallization temp. CONSTITUTION:A stock, which has 3.5-4.5% silicon content and contains MnS and AlN as inhibitor, or a stock, which has 3.5-4.5% silicon content and contains MnS and AlN as inhibitor and to which alloying elements, such as tin, are added in order to increase inhibitor effect, is finished to <=2.0mm plate thickness by means of hot rolling. Warm rolling is applied to the resulting hot rolled plate at 20-70% draft at a temp. range lower than the primary recrystallization temp. by 10-400 deg.C in order to increase the constraint of rolls for rolling, by which primary recrystallization driving force is provided and also the shear texture existing in the hot rolled plate is allowed to remain even after cold rolling. By this method, the volume fraction of (110)[001] oriented crystalline grains after primary recrystallization is increased by three or more times as compared with the one by the conventional method, and as a result, a sharp Goss structure can be developed after secondary recrystallization annealing even if silicon content is increased and thickness is reduced.

Title: Optical multiplex transmission system
Inventor: NAKANO HIROYUKI
IPC: H04J14/08
Filed: 1989-11-27
Abstract: PURPOSE:To simplify a transmission-side multiplexing device and to eliminate the need to provide a reception-side signal processor with a fast receiving circuit and a multiplexed signal demultiplexing circuit by making respective channels of a time-division multiplexed light signal mutually different in light frequency. CONSTITUTION:Source signals of channels 1-4 of a transmission part are multiplexed on a time-division basis into a binary time-division multiplexed signal, which is inputted to a modulating circuit 3. The bias signal from a bias circuit 4, on the other hand, has a staircase waveform which differ in level, channel by channel, and is superposed upon the multiplexed signal. Consequently, the time-division multiplexed light signal which differs in light frequency corresponding to the channels is obtained from a semiconductor laser 5. The light signal from the laser 5 is transmitted by a fiber 6 and separated in the state of the light signal through the optical filter 7 of a reception part. Then respective signals are passed through fibers 6a-6d and processed by optical receivers 8a-8d. A receiving circuit may be a low-speed circuit corresponding to the bit rate after the separation, an extremely fast separating circuit is not necessary, and a circuit with an existent operation speed is usable.

Title: Developing device
Inventor: SAKAMOTO HIROTSUGU
IPC: G03G15/08
Filed: 1988-12-01
Abstract: PURPOSE:To discriminate whether the developing device is before use or not without human errors by providing a transparent window in a developer storage part and detecting the presence or absence of a partition member by optical means, such as semiconductor light emitting element and light receiving element. CONSTITUTION:The transparent window 2 is provided in a part of the developer storage part 5. The semiconductor light emitting element 3 operates and the light beam thereof is made incident on the light receiving element 4 by transmitting the transparent window 2 and reflecting on the surface of the partition member 1 when a developing device 10 is mounted to the device before use. The presence or absence of the partition member 1 is thus discriminated. The partition member 1 does not exist if the developing device under use is mounted and, therefore, the light from the semiconductor light emitting element 3 does not arrive at the light receiving element 4. The presence or absence of the partition member 1 is thereby definitely discriminated. Whether the developing device is before use or not is, therefore, discriminated by the simple means. Such a trouble that the developer runs out during the course of printing and the images are not obtainable because of mounting of the developer under use is eliminated.

Title: Method for fusion splicing fluoride optical fibers
Inventor: SAKAGUCHI SHIGEKI
IPC: G02B6/24
Filed: 1986-12-22
Abstract: PURPOSE:To fusion and splice fluoride optical fibers with high mechanical strength at a low loss by heating and connecting the ends of said fibers in a dry inert atmosphere contg. at least one among HF, F2 and Cl2. CONSTITUTION:The ends of the fluoride optical fibers are fused and spliced in the dry inert atmosphere contg. at least one among HF, F2 and Cl2. Oxide formation on the surface is suppressed and, therefore, crystallization does not arise if the fiber ends are heated in such atmosphere. Formation of the scattered bodies of the oxide on the butt surfaces at the juncture is thus obviated and the fiber surfaces are not crystallized. The welding and connecting with the high mechanical strength at the low loss are thereby executed.
