Title: Hydraulic pressure control unit for x-piping type brake
Inventor: SHIMIZU HIDETOSHI
IPC: B60T8/26
Filed: 1982-12-24
Abstract: PURPOSE:To prevent a car from being deflected left and right when the piping system on one side fails by building up the captioned device with a first valve piston that is slidably fit in a cylinder bore and a secondary valve piston inserted in the same piston. CONSTITUTION:In an X-piping type brake in which the hydraulic pressure generated in a master cylinder 10 is supplied to the front and rear wheel brakes 28, 30 and 36, 38 on the diagonal lines of a car, respectively, hydraulic pressure control units 20R and 20L are disposed in each piping system. In this case, for each of the hydraulic pressure control units 20R and 20L, for example, when the hydraulic pressure in a hydraulic pressure chamber 16 cannot be increased, due to damaged pipe 22 a first valve piston 48 is moved against a spring 66 and a valve 70 is forced to sit on a valve seat 72, since the hydraulic pressure in the operation chamber 50 of the hydraulic pressure control unit 20R drops to zero. On the other hand, the valve 74 of a second valve piston 62 is prevented from sitting on the valve seat 72 and the hydraulic pressure is supplied as it is to the left rear wheel brake 38 from a hydraulic pressure chamber 14.

Title: Inspecting apparatus for optical fiber
Inventor: KOMIYAMA MAKOTO
IPC: G01M11/00
Filed: 1993-09-17
Abstract: PURPOSE:To measure the size and position of the defect of an optical fiber with high resolving power by allowing laser beam wherein frequency is swept and the reflected beam of pulse beam to interfere with each other and detecting the frequency and intensity of the obtained beat signal. CONSTITUTION:A driver 1 pulse-drives a first laser diode 2 and a driver 3 drives a second laser diode 4 in synchronous relation to the diode 2. The diode 2 emits pulse beam having narrow line width and a definite wavelength to an optical fiber 6 being an object to be measured through a half mirror 5. The beam made incident on the fiber 6 is reflected from the obstacle point of the fiber 6 to be again emitted to the mirror 5 and reflected by the mirror 5 to be emitted to a half mirror 8. Continuous beam wherein frequency is swept is emitted to the mirror 8 from the diode 4 in synchronous relation with the pulse beam and this beam and the reflected beam at the obstacle point are allowed to interfere with each other on a photodiode 7. A spectrum analyzer 9 measures the frequency and intensity of the obtained beat signal.

Title: Optical communication system
Inventor: OGAWA HARUKI
IPC: H04B10/032
Filed: 1984-11-05
Abstract: PURPOSE:To improve the reliability and high speed by bypassing automatically an optical transmission line of a communication station whose electric system has a fault, using a returned transmission data to allow a calling station to check the propriety, retransmitting data at each unit data and giving each communication station to a different wavelength band. CONSTITUTION:A data synthesis separator 21 consists of a branch device 211, a synthesizer 212, an own station call data/start data cut-off filter 213, a start data receiver 214, data transmitter 215, and a start data electric interrupter 216. The electric start data is subject to photoelectric conversion and transmitted together with a signal. The optical signal is branched to the filter 213, a transmission/reception control section 7 and the receiver 214 and only the branched light in the start data reaching the receiver 214 is made effective. The interrupter 216 interrupts the start data called from the own station and passes the others. Thus, communication is started. Only when the wavelength of the reception data is the same as the set wavelength in the control section 7, the data is received and in other cases, the data is interrupted. If the returned transmission data is faulty, the calling station makes retransmission at each unit data. The filter 213 is controlled by the control section 7 and if the own state is failed, the interruption function is lost.
