IPC: E04B1/58
Filed: 1998-04-24
Abstract: PROBLEM TO BE SOLVED: To provide the seismic control material of an inexpensive and easy-to- handle building by making it expandable in simple constitution. SOLUTION: The ends 11, 21 of a pair of steel pipes are oppositely disposed in a short connection steel cylinder 3 disposed at a substantially center position at an interval of 1-2 cm, and elasto-viscous material 4 of asphalt-based material exists between the inner periphery of the connection steel cylinder 3 and the outer periphery of the steel pipe ends 11, 21 in the connection steel cylinder 3.

Title: Signal input output device
Inventor: ASAHI SHIGEO
IPC: H02H3/24
Filed: 1990-04-27
Abstract: PURPOSE:To prevent an interface from receiving a signal in an interruptible state by supplying power from an opposite party to the interface of its own device even when a power supply of a control section is interrupted. CONSTITUTION:When a voltage of a power supply P1 is zero in the occurrence of a fault and a power supply of a control section 1 is failed, power is supplied from a power supply P2 of a control section 2 to interfaces 8, 10 and an inverter 12 via a diode 15 or the like. Thus, an event of a signal coming from an opposite party to the interface 10 in an interruptible state resulting in latching up a CMOS IC circuit being a component of the interface 10 into destruction is prevented. Simultaneously, since an output of the inverter 12 is inverted to an H level in response to the interrupted power supply P1, the interface 10 is inactive to block the signal passing from the opposite party. Thus, a fault of causing an excess voltage drop to a transmission line 7 or of causing a large drop in the output voltage of the power supply P2 is prevented.

Title: Device and method for separating activated carbon
Inventor: YAMAMOTO MASAHIRO
IPC: B01J20/34
Filed: 1999-04-22
Abstract: PROBLEM TO BE SOLVED: To separate activated carbon recovered from the markets in a state scarcely containing calcium-based particles mixed with the activated carbon. SOLUTION: A slurry-forming means 2 is used for charging water and a recycled material comprising recycled carbon particles and calcium-based particles in a mixed state into the slurry-forming means 2 to prepare the slurry in which the carbon particles and the calcium-based particles are dispersed. A separation means 1 has a cylindrical container portion 4, a carbon particle- recovering portion 5 disposed on the upper side of the cylindrical container portion 4, and a calcium particle-discharging portion 7 disposed on the lower side of the cylindrical container portion 4. The slurry from the slurry-forming means 2 is charged into the cylindrical container portion 4 in its tangential direction and then revolved in the cylindrical container 4 to improve the dispersion of the carbon particles and the calcium-based particles.  The carbon particles are floated on the upper side of the cylindrical container portion 4, and the calcium-based particles are precipitated on the lower side of the cylindrical container portion 4. Thereby, the carbon particles and the calcium-based particles can be separated from each other substantially without being mixed.

Title: Inner temperature measuring apparatus
Inventor: MATSUMOTO TAKAHIRO
IPC: G01K5/52
Filed: 1995-04-17
Abstract: PURPOSE: To obtain an apparatus for measuring the inner temperature accurately even for high temperature sample. CONSTITUTION: When a sample 10 is irradiated with laser light from a laser light source 11 for generating ultrasonic wave, an ultrasonic wave is generated in the sample 10. An ultrasonic detecting section 20 detects an echo of the ultrasonic wave as a Doppler shift of laser light emitted from a laser light source 12 for probe thus determining the propagation time of ultrasonic wave. The propagation time depends on the inner temperature. On the other hand, a surface temperature measuring section 30 determines the temperature of scale based on the Raman scattering of laser light emitted from the laser light source 12 for probe. That temperature is regarded as the surface temperature of the sample. When the temperature is locally distributed in the sample 10, the temperature distribution can be approximated by a specific function including unknown parameters.  An arithmetic section 40 calculates the unknown parameters based on the measurements and determines the function. Finally, inner temperature of the sample is determined according to the function.

Filed: 1985-05-29
Abstract: PURPOSE:To prevent the same part of a magnetic tape from being damaged by delaying a stop control signal for stopping the traveling of the magnetic tape by a variable time and then sending it to a tape traveling driving part, and controlling the delay time of a variable delay circuit dispersedly. CONSTITUTION:The stop control signal S1 is inputted to a stop control signal input circuit 1 with the stop key on the console panel of a magnetic tape reproducing device and a stop control signals S2 is outputted. The stop control signal S2 is inputted to the data load terminal 4 of a down counter 2a.

At this time, the stop control signal S3 is delayed behind the stop control signal S2 and inputted to a tape traveling driving part 3 and tape traveling stop operation starts immediately after the signal is inputted, so that the magnetic tape reproducing device enters a stand-by mode. Consequently, data are prevented from being destroyed and the life of the magnetic tape is prolonged.

IPC: G01N21/90
Filed: 1987-05-14
Abstract: PURPOSE:To enable the presence or absence of a label adhered to the surface of a glass bottle regardless of the contents in the glass bottle, their materials and configurations by selecting the presence or absence of the label as a difference in a light transmittance in the thick wall portion of the glass bottle that is thick with respect to the incident light from an illuminator. CONSTITUTION:A label inspecting instrument 10 is composed of an illuminator 1, a television camera 3 and an image processor 4. The illuminator 1 is arranged as opposed to the camera 3. A glass bottle 2 carried by a conveyor is passed between the illuminator 1 and the camera 3. Incident light (a) from the illuminator 1 is irradiated on the bottle 2. Since the incident light (a) is hardly transmitted through the thick wall portion (b) of the bottle 2 when a label 5 is adhered to the surface of the bottle 2 and the incident light (a) is transmitted through the thick wall portion (b) when the label 5 is not adhered to the bottle 2, the presence or absence of the label 5 can be selected by the image processor 4. Accordingly, the presence or absence of the label can be easily and surely detected regardless of the configurations and materials of contents.

Abstract: PURPOSE:To realize a system for preventing a shifting of position among slices of a plurality of substances having different resonance frequencies. CONSTITUTION:Data D1 are collected by exciting the slice at the fixed position by the use of an exciting pulse RF1 having both a center frequency which coincide with a resonance frequency Fw of substance w, and having a slice slope G1.
