Title: Shaft sealing device for pump
Inventor: INOUE TORAO
IPC: F04D29/10
Filed: 1981-11-30
Abstract: PURPOSE:To prevent a shaft sealing device from direct contact with liquid in a pump by sending compressed air from the exterior of the pump. CONSTITUTION:When compressed air is introduced from a compressed air introducing pipe 8 to the periphery of a shaft, it fills a space around the shaft and then a empty chamber 4 to be injected from an outflow 10 provided in the outside wall of the empty chamber 4 to the exterior of a pump. When the pump is started, the neighborhood of a shaft sealing device 5 in a space of the upper portion of an impeller 2 tends to have negative pressure. However into this portion is always introduced compresed air so that the shaft sealing device 5 cannot be damaged by pressure variation. Thereafter, in running and stopping of the pump the shaft sealing device 5 can be prevented from direct contact with liquid in the pump by the compressed air.

Title: Digital signal transmitter
Inventor: HIYAKUDAI TOSHIHISA
IPC: H04L27/20
Filed: 1993-07-09
Abstract: PURPOSE:To simplify the circuit configuration on a demodulator side remarkably by inserting sequentially a data group comprising the predetermined number of non-signal data to each data series of a time domain in a predetermined timing. CONSTITUTION:A real part time series data group D7 and an imaginary part time series data group D8 outputted from an IDFT arithmetic operation circuit of a modulation section 41 are fed sequentially to a buffer memory circuit 42 (insert means). The circuit 42 stores sequentially the real time domain data forming the data group D7 fed from the circuit 7 and the imaginary time domain data from the data group 8 and adds L sets of non-signal data D40 to the stored data every time N-sets of the data are stored and provides the result in the lump repetitively. Then an additional real time domain data group D41 and an additional imaginary time domain data group D42 in which a valid signal period and a non-signal period are alternately arranged are formed and fed sequentially to a D/A converter circuit 8. Since arithmetic operation is performed in an accurate timing to each of the data series of the time domain, the circuit configuration of the demodulator side is simplified.

Title: Roof ventilator
Inventor: NAGANO TATSUHIRO
IPC: E04B7/18
Filed: 1993-08-05
Abstract: PURPOSE:To enhance waterproofing properties and moisture barrier properties when it is rainy or highly wet by installing a moisture absorption and expansion material, which expands and closes a ventilation passage by absorbing the moisture, to the ventilation passage of a ventilation device on a roof. CONSTITUTION:A moisture absorption and expansion member 26 is installed in the longitudinal direction where the member 26 is designed to expand by absorbing moisture into the inner surface of each of slanting boards 22 for a cover 13 opposed to a contact plate 19 of a base 12. This moisture absorption and expansion member 26 expands if the moisture exceeds 100% when the member is directly exposed to rainy water or dew condensation water and comes in contact with the end of the contact plate 19 of the base 12, thereby closing a ventilation passage 14. This construction makes it possible to prevent rainy water or moisture from penetrating the side of a vent hole 16 even when the rainy water and moisture enters the ventilation passage 14 with a strong wind from an exhaust air port 25. The moisture absorption and expansion member 26 discharges water contact when it is dried while its cubic capacity is reduced and opens the ventilation passage 14. It is, therefore, possible to enhance waterproofing properties and moisture barrier properties.

Title: Tap change-over device during three-phase load
Inventor: SOGABE KEIJIRO
IPC: H01F29/04
Filed: 1985-09-05
Abstract: PURPOSE:To efficiently perform the changeover of taps by a method wherein, an arc is prolonged due to a lowered breaking performance of a valve for a main contacts, an arc is produced with an auxiliary contact, and the arc is detected with an optical detection element so as to prevent the shortcircuiting between the taps. CONSTITUTION:When a main contact valve HA is opened to extinguish an arc, a load current IL flows from a valve WA for resistance contact to a neutral point NP via a limit flow resistor RA. Then, when a valve WB opens, a load current of each phase is divided into two flows; from the valve WA to the neutral point NP via the resistor RA and from the valve WB to the point NP via the resistor RB, and, at the same time, a horizontal flow that is determined by a step voltage US and resistors RA and RB flows in the direction of WA-RA-RB-WB. At this time, an auxiliary contact KA opens, and the contact KB closes, however, the current does not flow non produce an arc, with the arc being already extinguished. Then, the valve HB is opened so that the current does not flow even if the contact KB closes. Then, the valve WA opens to break the sum of the load current and the horizontal flow, with the load current transferring to the valve WB - the resistor RA and there is no horizontal flow. Then, the valve HB closes, with load current flowing.
