Abstract: PURPOSE:To make instant fire extinction at a time of an overturn of a combustor reliable and to improve safety by providing a releasing device so that an opening and closing shutter for an ignition access hole is released when a liquid fuel combustor is overturned forwards. CONSTITUTION:At a time of ignition, an ignition window is opened by the  action of an operation unit 25 and a shutter 24.

A drainage port at the lower part of the washing vessel 3 and a discharge port at the bottom part of the dehydrating vessel 4 are communicated by a drainage pipe 6a and connected to a drainage hose 7. A fixed holder 6b provided at the drainage pipe 6a is fitted to the cylindrical body 12 and fixed. On the other hand, the cylindrical body 12 and the fixed holder 6b are integrally molded into respective parts. Thus, since the washing machine is held at three points by the fixed holder 6b, washing vessel 3 and cylindrical body 12 of the dehydrating vessel 4 while being formed integrally with the drainage pipe 6a, noises are prevented from being generated by abnormal vibrations.

IPC: H04N5/445
Filed: 1981-03-20
Abstract: PURPOSE:To obtain excellent, easy-to-see character display by removing a character part from a color video signal by a black-and-white signal for character display, adding a color singal for character display to this part, and varying the amplitude values of both the signals in relation to each other. CONSTITUTION:When a color video signal (a) is inputted to a terminal 1 and a black-and-white Y signal (b) for character display is applied from a character broadcast receiving circuit to a terminal 5, an Y' signal (c) appears at an intersection 18, and a signal (d) generated by removing a character part from the video signal (a) appears at an intersection 3. Then, a color signal for character display, e.g., an R signal is applied to a terminal 23 and synthesized with the signal (d) at the intersection 3 through transistors 6 and 7, obtaining a singal (e) at an intersection 8. A peak voltage at the terminal 23 and waveform (c) at the intersection vary with a voltage v0 at the neutral point 10 of a variable resistor 12, and the video signal at the intersection 3 is clamped to the V0 only at the part of a character inverted signal Y like waveform (d). Consequently, the lag of waveform is eliminated and characters are displayed in an easy-to- see state without reference to a background image.

Title: Control device for elevator
Inventor: UETANI KENICHI
IPC: B66B3/00
Filed: 1990-02-23
Abstract: PURPOSE:To reduce the number of circuits by switching the control, which is performed by rocal control means, to the backup operation control with both sigals of the failure signal from a failure detecting means for detecting the failure and the backup operation command signal at the time of failure of a monitor control means. CONSTITUTION:When a failure of an elevator monitor control device 40 is detected by a failure detecting means 40b, the detecting signal is input to a failure signal input device 30f of a system control device 30, a CPU 30a has such control as not to transmit the control operation control signal to elevator control devices 20-23 through a transmission device 30c. On the other hand, when the backup operation command switch 50 is operated, the signal is transmitted to the control device 30 through an amplifying device 70. When this signal is input to a backup operation command input device 30e, the CPU 30a outputs the predetermined backup operation command stored in a storage device 30b to the control device 20 through the transmission device 30c. The number of circuit between a control center and the control device 20 can be therefore reduced.
