IPC: G01N27/72
Filed: 1984-07-18
Abstract: PURPOSE:To identify ferromagnetic material in a non-destructive manner and quickly, by analyzing changes in the acoustic emission level (AEM level) with respect to hourly changes (dB/dt) in the internal magnetization through an external AC magnetic field to determine a pattern identification parameter. CONSTITUTION:This method has an AC power source 14 which applies an external AC magnetic field to an object 10 to be measured by exciting a non-contact electromagnet 12 and a dB/dt measuring element 16, an AEM sensor 18 and an external magnetic field measuring element 20 all arranged in contact with the object 10 separately. A pattern identification parameter is derived based on the averaging computation for converting the AEM level with respect to the dB/dt into X-Y mode and the display of a waveform analyzer 22 to decide on the type of material with a pattern recognition device 24 corresponding to the reference parameter prememorized. Thus, the type of ferromagnetic material as the combination of main chemical components and manufacturing method can be identified in a non-destructive manner and quickly.

Patent JP-H0440734-A (JP)
Title: Video telephone system
Inventor: OSAWA HIROSHI
IPC: H04M11/06
Filed: 1990-06-07
Abstract: PURPOSE:To attain the reproduction of the correct information even when the communication is carried out with use of plural channels by cutting a circuit by means of a timer if the different information is not received from the same calling side. CONSTITUTION:Suppose no signal arrives at two B channels B1 and B2 from a digital circuit (a). In this case, a circuit interface 3 sends a message to a CPU 4 to show the reception of an incoming call so that a system control part 2 has no malfunction of control at reception of the incoming call. The CPU 4 starts a timer 14 and waits for arrival of the information from another channel before the timer 14 counts up the due time. If the information received from another channel is identical with the information received from the same calling side, a circuit is connected. Meanwhile the CPU 4 decides no information received from the same calling side in a time-over state and inhibits the calling to cut a digital circuit (a). As a result, the correct information can be reproduced despite the use of plural channels. Then the troubles caused at connection of the circuit can be decreased.

Title: Multieffect screw compressor
Inventor: NOZAWA SHIGEKAZU
IPC: F04C18/16
Filed: 1979-11-21
Abstract: PURPOSE: To improve the cooling effect by bringing the return port of intermediate pressure gas to the process more than one pitch downstream of a post rotor 1 after choking the sucked gas, while making the size of a return port of intermediate pressure gas smaller the tooth depth of a female rotor to prevent the counterflow of intermediate gas to the suction side.  
     CONSTITUTION: Number 8 is a portion of a casing for a screw compressor 1. An intermediate pressure gas return port 9 to be connected with an intermediate pressure gas line 7 is located at the position departed by distance L which is longer than the pitch P of a rotor 10 from the choking position A of a female rotor 10 or at the position more than one pitch downstream from said rotor 10. The size t 2  of said port 9 is made smaller than the tooth depth t 1  of the female rotor 10. Since there is no counterflow to the suction side of the intermediate pressure gas pressure supplied from the intermediate pressure gas line 7 through said port 9 to the rotors, the gas can be sucked effectively from main system path resulting in sufficient cooling effect.

Title: Device to be recycled
Inventor: YANO HIDETOSHI
IPC: B65H43/00
Filed: 1993-06-22
Abstract: PURPOSE:To make it possible to adequately exchange the members which constitute a device and run out of their life while effectively utilizing the respective parts to their life and by applying visually recognizable elements for classifying of these members. CONSTITUTION:A front cover 20a, side covers 21, etc., and an external cover of the image forming device consist of a synthetic resin. The service life of such synthetic resin members is nearly semipermanent and, therefore, these members are able to be recycled. The members to be reused are, thereupon, previously determined to be colored blue, the members to be used for other purpose to be colored yellow and the members to be discarded to be colored red at the time of classifying the members to reuse, use for other purpose and discard. For example, if the front cover 20 is previously colored red and the side cover 21 blue, the easy judgment of the classification by colors is thus possible at the point of the time of disassembly for recovery. The members, such as external cover, which appear in the overall appearance of the device may be classified with the prescribed colors only in the inner parts when assembled as the entire part of the device. As a result, the classification according to the recycling forms is facilitated.
