Title: Car type discriminator
Inventor: HOSHINO HIROSHI
IPC: G01B11/24
Filed: 1992-04-23
Abstract: PURPOSE:To secure a highly reliable car type discriminator that can judge a car type in a highly accurate way and, what is more, stably operable for a long period of time without requiring a wide space. CONSTITUTION:Each detection signal of a car body is outputted out of respective passing sensors 11-1, 11-2 and so on of a silhouette sensor 11. These detection signals are fed to a silhouette forming means 13, through which each wheel of the car body is detected from a detection signal of the passing sensor set up in a lower part K of the silhouette sensor 11, and on the basis of this wheel position, silhouette data of the car body are originated from all detection signals of the silhouette sensor 11. In succession, the silhouette data are compared with the reference silhouette data by a judging means 17, thus a car type is judged aright.

Title: Overvoltage protection circuit for thyristor inverter
Inventor: KUBOTA YOSHIO
IPC: H02M7/515
Filed: 1978-08-28
Abstract: PURPOSE: To protect thyristors from damage, by coupling an overvoltage detection circuit in parallel between a power rectifier and a power inverter.  
     CONSTITUTION: The overvoltage detection circuit 5, which comprises a high resistor 6 for dividing a voltage, a variable resistor 7 for adjusting a set voltage, a PUT 9 whose emitter is coupled to the variable resistor, and a reference voltage source coupled between both the bases of the transistor 9, is coupled in parallel between the power rectifier 3 and the power inverter 4. When the voltage exceeds a reference voltage due to a surge or the like, the PUT 9 is turned on and a current flows to a current amplifier 11 through a base terminal B 1 . The current signal amplified by the amplifier 11 is supplied to the gate of a thyristor 12 to turn it on to make a short circuit. As a result, the voltage applied to the thyristors of both the converter and the inverter are quickly eliminated. Therefore, the thyristors are protected from damage.

IPC: H04W88/14
Filed: 1998-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent congestion of communication elements due to quality degradation of a communication path in the case of conducting flow control in an asynchronous transfer mode ATM communication network that contains the available bit rate ABR service. SOLUTION: A radio communication interface 101 always monitors quality of a radio communication channel connecting to itself and gives error information to a resource management RM cell generating section 104 when the quality is degraded to be a reference value or below. Upon the receipt of the error information, the RM cell generating section 104 generates spontaneously a backward RM cell to a transmission source user of a virtual connection VC managed by a VC table section 102 at a time interval informed of a periodic timer section 103. The backward RM cell is multiplexed with an ATM cell outputted from a radio interface 101 at a multiplexer section 105 and the multiplexed cell is sent to the transmission source user via an ATM interface 100.  Thus, communication elements interposed between the transmission source user and a base station device 320 can surely receive the backward RM cell and congestion is displayed for it.

Title: Control device for vacuum valve
Inventor: MURAYAMA YASUHIRO
IPC: F16K31/126
Filed: 1994-05-20
Abstract: PURPOSE:To maintain both front and rear chambers at an atmospheric pressure after a lapse of a specified time even when the release time of a vacuum valve is lengthened and to forcibly close a vacuum valve by a method wherein the front and the rear chamber of a vacuum valve are allowed to intercommunicate with an atmosphere introduction pipe and a flow rate regulating means, such as a throttle valve, is located in the atmosphere introduction pipe. CONSTITUTION:With a vacuum valve 1 released, the rear chamber 1g of a cylinder chamber is brought into a vacuum state and air is introduced to a front chamber 1f through an intake exhaust conduit 29 by means of a vent pipe. In which case, since an atmospheric pressure introduction pipe 31 is connected to the rear chamber lg, air through a feed discharge conduit 29 flows in trace amounts to the rear chamber 1g through the atmospheric pressure introduction pipe 31 and a throttle valve 32. After a lapse of a specified time, the interior of the rear chamber 1g is brought into an atmospheric pressure. When, as noted above, the rear chamber 1g is brought into an atmospheric pressure simultaneously with the front chamber 1f, a piston 1 is energized and pushed out by a spring 1e and the valve body 4 is brought into contact with a valve seat 1b and the vacuum valve 1 is closed. Thus, even when the release time of the vacuum valve 1 is lengthened, the vacuum valve l is forcibly closed after a lapse of a specified time.

Abstract: PURPOSE:To enable a measurement range to be wide and at the same time sensitivity, reliability, and safety to be improved by providing a plurality of pressure sensors and then relating these mutually for outputting an optimum measurement pressure from a signal conversion part. CONSTITUTION:A measurement pressure P is introduced from a through hole 31 and pressure signals PA, PB, and PC are output from all of pressure sensors 34A, 34B, and 34C to a signal conversion part 39 through each lead wire when the value is for example within 0-2kgf/cm<2> range. The signal conversion part 39 selects the pressure signal PA from the sensor 34A which outputs a pressure signal with the highest sensitivity and then outputs it as a pressure signal P0. In the similar manner, when the measured pressure P is for example within 2-20kgf/cm<2> range, the signal conversion part 39 selects a signal PB from the sensor 34B. Also, when the measurement pressure P is for example within 20-200kgf/cm<2> range, the signal PC from the sensor 34C us selected and is outputted as a pressure signal P0, thus enabling an output signal in the most suitable measurement range to be adopted out of a plurality of pressure signals.
