Title: Hydraulic power generating equipment
IPC: F03B11/06
Filed: 1992-03-19
Abstract: PURPOSE:To provide hydraulic power generating equipment reduced in its longitudinal measure by reducing the longitudinal measure of an electric rotary machine and a hydraulic machine. CONSTITUTION:In this hydraulic power generating equipment, the runner of a hydraulic machine connected to the main shaft 6 of an electric rotary machine, and a guide vane 40 for controlling water quantity to the runner 22 are disposed in a waterway between an upper cover 23 and a lower cover. The operating shaft of the guide vane 40 is provided with an operating mechanism part 44 disposed on the lower cover side so as to rotate the operating shaft, and a thrust bearing 15 is provided between the upper cover 23 and the main shaft 6 of the electric rotary machine. As a result, the pressing force of the upper cover 23 lifted upward by water pressure works on the thrust bearing 15, but this pressing force is nullified by the self-weight of the electric rotary machine. The pressing force is thereby reduced by that part, and the thickness of the upper cover 23 can be made thin, so that the longitudinal measure of the hydraulic power generating equipment can be reduced. Also, since the operating mechanism part 44 is disposed on the lower cover side, the electric rotary machine and the hydraulic machine can be assembled separately.

Title: Cogeneration system for internal combustion engine
Inventor: SHIMODA KUNIHIKO
IPC: F02G5/04
Filed: 1987-03-20
Abstract: PURPOSE:To enable a power absorbing machine to effectively operate when the temperature of hot water in a heat storage tank is lowered, thereby to make it possible to eliminate an auxiliary burner from a heater by injecting liquid into the power absorbing machine when the demand of output power is low. CONSTITUTION:When the demand of output power 13 is low while the demand of high temperature hot water 45 is high, the temperature of a heat storage tank 44 lowers. A temperature sensor 63 delivers a lowered temperature signal to a controller 64 which therefore opens a control valve 55, and therefore water is filled in a power absorbing machine 51. Since blades and the like agitate the water, the temperature of the water in the machine increases greatly. The water in the power absorbing machine 51 whose temperature has increased is fed into a heat-exchanger 53 by means of a water pump 52, and the water lowers its temperature after heating cold water 61 from the outside, and is then returned to a water tank 52. With this arrangement, the temperature of the high temperature hot water 45 may be maintained at a predetermined value, and therefore, it is possible to eliminate the necessity of an auxiliary burner, thereby it is possible to reduce the risk of explosion or the like, greatly.

Title: Catv system equipped with furtive glance and hearing preventing function
Inventor: INOUE NOBUTAKA
IPC: H04N7/167
Filed: 1987-03-19
Abstract: PURPOSE:To prevent the furtive glance and hearing of a television signal transmitted from a head and on the side of a terminal by superimposing an interfering wave which has FM-modulated on the residual side wave band of a video signal in a television signal inverted on a frequency. CONSTITUTION:Firstly, the television signal outputted from a television signal generation means M4 is inverted on the frequency in an inversion means M5 in the head end M1. The interfering wave outputted from an interfering wave generation means M6 is superimposed on the residual side wave band area of the video signal in the inverted television signal by an interfering wave superimposing means M7. In a terminal equipment M2 to which a glance and hearing permitting signal is not inputted, the action of an inversion means M8 which inverts the television signal from the head end M1 is prohibited by an inverted action prohibiting means M11. Since the television signal which is not inverted is inputted to a band removing means M10 which removes a low pass from the frequency of the interfering wave inverted on the frequency, the interfering wave is not removed, and a voice signal is removed.
