Title: Optical transmission system
Inventor: TANAKA NOBUYUKI
IPC: H04B10/07
Filed: 1988-03-10
Abstract: PURPOSE:To prevent a fault due to a laser beam by sending fault detection information to an opposite station if an optical signal from the opposite station is interrupted and allowing the opposite station to stop the output of a laser light emitting element based on the said fault detection information. CONSTITUTION:An electric signal inputted externally is given to a drive control section 32 via a multiplex section 31 to drive a laser emitting element 11 thereby applying optical transmission. On the other hand, the received optical reception signal (a) is converted into an electric signal by a laser reception element 12, amplified by an amplifier 33 and outputted externally via a demultiplex section 34. If an optical reception signal (a) from an opposite station is interrupted, it is detected by a fault detection section 35, fault detection information (b) is multiplexed with the input electric signal by a multiplex section 31 and the result is sent to the opposite station. On the other hand, upon the reception of the fault detection information (b), a laser light emission block circuit 36 is activated to stop or interrupt the lighting of the laser beam emitting element 11 thereby preventing a fault of the operator. Thus, the safety is improved.

IPC: G01D21/02
Filed: 1983-04-01
Abstract: PURPOSE:To form a sensor of a simple structure, which has functions of detecting the abrasion limit of a brake lining and detecting an abnormal temperature of brake oil by disposing a sensor in which a thermal sensitive element and non- contacting detecting means such as a proximity switch or the like are united in a body at a predetermined place of a wheel cylinder portion of a brake. CONSTITUTION:A thermal sensitive element 13 for detecting an abnormal rise of temperature of brake oil 5 and a proximity switch 12 for non-contact detecting a change of position of a piston 4 moved by abrasion of a brake lining 1 are united in a body and incorporated in a sensor case 14, thereby forming a sensor 11. The sensor 11 is set at such a position of a wheel cylinder portion 3 of a brake in such a manner that when the piston 4 advances up to the abrasion limit of the brake lining 1, the proximity switch 12 is operated. In this arrangement, the limit of abrasion is easily non-contact detected by utilizing the movement of the piston 4 caused by abrasion of the brake lining 1, and an abnormal rise of temperature of the brake oil 5 is detected by the thermal sensitive element 13.

Title: Load measuring system for local area network
Inventor: TAGAMI KUNIO
Filed: 1988-03-14
Abstract: PURPOSE:To attain load measurement at an optional point of time without giving any effect onto the transmission efficiency of a LAN by measuring a token packet circulation number in the no load state and a token packet circulation number in the operating state so as to measure the load. CONSTITUTION:A transmission enable control section 20 of a loop interface 220 uses at first a global address to transmit an inhibition packet to each communication node so as to bring the LAN into the no load state. Since only the token packet is circulated, a token counter 18 is counted up every time a reception circuit 11 receives the token packet and the count for a prescribed time is stored in a memory. Then a releasing packet is sent to bring the state into the operating state. Even in the operating state, the number of circulation of the token packet is counted by a prescribed time T only and stored in the memory. An external system 210 obtains the communication load of the LAN from the comparison of the two measured values.

Title: Quantitative feed amount for liquid and device thereof
Inventor: ARIMA HIROTADA
IPC: G01F13/00
Filed: 1980-04-30
Abstract: PURPOSE:To obtain a quantitative feed method and a device thereof which is manufactured at an inexpensive cost and has an improved precision, by a method wherein overflow of liquid from one tank to the other is detected at a connection pipe connecting together two liquid tanks having water feed valves and water discharge valves. CONSTITUTION:Two liquid tanks 5 and 6 provided with water feed valves 1, 2 and water discharge valves 3, 4 are coupled together, and are mutually equalized in a capacity of a part covering from below a connection part 7. A detector, which detects overflow of liquid from a tank to the other, is mounted at the connection part 7. Liquid is poured into the liquid tank 5 through an opening of the water feed valve 1 in a condition to close water discharge valves 3 and 4. When overflow is caused, the water feed valve 1 is closed, and the water discharge valve 3 is opened to discharge the liquid. After water discharge is completed, the water discharge valve 3 is closed, and the water feed valve 2 is opened to feed the liquid into the liquid tank 6. Operations described above are performed in the liquid tanks 5 and 6, and this prevents wasting of an overflow liquid and permits an alternate measuring of a constant amount of liquid.

Title: Discriminating device for sound to be measured
Inventor: INOUE SATORU
IPC: G01H3/00
Filed: 1979-05-10
Abstract: PURPOSE: To discriminate and detect abnormal sound with good accuracy by multiplying and dividing the output signals of the respective detectors which detect disturbing noise and the sound generated from the object to be measured respectively.  
     CONSTITUTION: Factory noises are input to a multiplying-dividing circuit 10 by way of a microphone 2, analog delay circuit 9, etc. On the other hand, the sound generated from the object to be measured is input to the multiplying-dividing circuit 10 by way of a microphone 3, etc. When both inputs thereof are of the same level, the multiplying-dividing circuit 10 outputs their product and when the levels of both inputs vary, it makes level correction and outputs their product. These are then supplied to a sum average circuit 13 by way of a positive value average circuit 11 and negative value average circuit 12 respectively. Thence, in a decision circuit 16, the output levels of the average circuits 11, 12, 13 are discriminated and further logic operations are accomplished, whereby the presence or not of any abnormal noise and the cause for the same are decided. Since in this way no influences are given to the discrimination even if disturbing noises become large, the abnormal noise may be discriminated and detected with good accuracy.

In the aforesaid constitution, torsional moment generated on the disc in starting and braking a vehicle approximately agrees to the fibrous orientation of the disc internal layer 5 and can be resisted by said layer 5. Also, bending moment agrees approximately to the fibrous orientation of the intermediate layers 6 and 7 and the external layers 8 and 9, and is resisted by said layers 6 and 7, and 8 and 9. Therefore, strength can be increased against bending moment and torsional moment.
