IPC: B01D1/22
Filed: 1984-04-13
Abstract: PURPOSE:To improve evaporation efficiency, recover the solid by prearranged quantity and carry out drying treatment of the solid in accordance with drying speed by evaporating the liquid of a treated fluid containing the solid over a wider area and also providing sufficient evaporation heat to the treated fluid. CONSTITUTION:Part of a treated fluid containing the solid is caused to stick to the surface of rotary blades 2 by rotating the rotary blades 2 and a drum 3 in an integral form, and the liquid is flash-evaporated in the decompressed atmosphere of an evaporation can 1. After this process, the solid remaining on the surface of the rotary blades 2 is scraped off by a scraping plate 11 and is recovered through a solid discharge port 7. At that time, the rotary blade 2 is heated by hot water or steam through the drum 3, so it can have sufficient evaporation heat for the liquid, and also for efficient separation of the liquid and the solid. At the same time, the rotary blade 2 can take out the solid by a required quantity because it carries out flash evaporation of the treated fluid through attachment of a part of the quantity on the surface of the rotary blade 2.

Title: Re-closed circuit relay
Inventor: NARAKI YOICHI
IPC: H02H7/26
Filed: 1990-03-27
Abstract: PURPOSE:To shorten the time required for detection of a permanent trouble by monitoring an earth current flowing in a cable shielding layer by a re-closed circuit relay for disconnection of the faulty block only by the breaking operation of a breaker without getting the faulty block in conduction again. CONSTITUTION:In the case that a short circuit happens in a first block of a distribution line, a greatly large current flows in the distribution line and an earth cable 8. On the side of the distribution line, an over-current relay 4 located just before a breaker 1 operates due to the trouble, sending an operation command to a re-closed circuit relay 6 for switching a breaker 'OFF' to stop a transmission of electrical energy to the distribution line. On the other hand, a current flows in the earth cable 8 and therefore a grounding over-current relay 7 works. The re-closed circuit relay 6, being prohibited by a signal sent from the grounding over-current relay 7 from operating, does not send the 'siwtch ON' command to the breaker 1. Therefore, re-closing of the circuit is not conducted and disconnection of the trouble block is finished.

Title: Optical measuring system
Inventor: TSUMURA TOSHIHIRO
IPC: G01S5/16
Filed: 1992-02-26
Abstract: PURPOSE:To obtain an optical measuring system which can always accurately measure the three-dimensional positional relation between an object to be measured to which a light source station is installed and a measurement reference position to which a reflecting station is installed. CONSTITUTION:A plurality of recurrent reflectors CC are arranged at arbitrary intervals beside the running course 2 of a traveling object 1. The reflectors CC have an optical property which reflects incident light in the direction opposite to the incident direction. A laser measuring instrument 3 mounted on the object 1 makes scanning by turning two surface beams 41 and 42 having different inclination along reference planes belonging to the object 1. The instrument 3 detects the rotational scanning angle when the beam 41 or 42 hits one of the reflectors CC by detecting the reflected light from the reflector CC. The current position and inclined angle of the object 1 in a three-dimensional space are calculated based on the detected rotational scanning angle, inclined angles of the surface beam, and coordinate positions of the recurrent reflectors.

Abstract: PURPOSE:To reduce current consumption of a radio telephone set considerably when a power failure takes place by providing a 2nd detection means detecting a drop of a voltage applied in response to the detection by a 1st detection means detecting a decrease in a charging voltage at a charge terminal of a radio telephone set side. CONSTITUTION:When a voltage drop at charging terminals 300, 400 of a radio telephone set is detected, prescribed power is applied from the radio telephone set to the charging terminal, and when the consumption of the power is detected, the state in this case is discriminated to be in a power failure state and the power supply to each circuit of the radio telephone set is reduced. That is, since the radio telephone set is disconnected from a charger in a normal off- hook state, even when power is applied to the charging terminals 300, 400 from the radio telephone set in the timing, the power is not consumed and the power failure state or the like is accurately discriminated. Since the current supply to each part constituting the radio telephone set is reduced, the current consumption at a power failure or the like is reduced.
