Title: Transmission system switching equipment for multi-direction multiplex communication equipment
Inventor: SUGIHARA SHIGERU
IPC: H04B1/74
Filed: 1988-03-22
Abstract: PURPOSE:To reduce cost and passing loss by providing a high frequency switch to switch-output the output of the transmitter of a living system and the output of the transmitter of a spare system by a system switching signal selectively and a means to stop-control the transmitting action of the transmitter of the system of a non- operating side based on the system switching signal and executing a transmitting system switching. CONSTITUTION:When a system switching signal to instruct the selection of a living system, for instance, is outputted from a switch-control circuit 3, a high frequency switch 4 selects the output signal of a living system transmitter 1 as a transmission high frequency signal. Then, the living system transmitter 1 is controlled to send a transmission signal for the high frequency switch 4 by inputting the system switching signal to a power source switch 9. On the other hand, since the system switching signal inversed through an inverter 11 is inputted to the power source switch 10 in a spare system transmitter 2, a high frequency amplifier 8 is controlled to stop an transmitting action. Consequently, since the stage number of a diode is small and an isolation quantity can be reduced, the whole device can be inexpensive and low passing loss is realized.

IPC: G03B27/34
Filed: 1979-05-30
Abstract: PURPOSE:To prevent solid black and improve the life of the cleaning member by putting the portions other than image regions on photoreceptor surface into a noncharge state by the use of the light for a light source for exposure at the variable power copying. CONSTITUTION:A lens assembly 11 is of the construction incorporating a lens 11b into a holder 11a being a moving shield body and has a function of changing magnification. When the lens assembly 11 is in the original size position, the light of the optical path is radiated to the entire surface (a) in the photosensitive surface C' through the lens 11b, by which the image is formed over the entire surface. When the lens assembly 11 is in the reduction position, the light of the optical path is radiated only to the central portion (b) in the photoreceptor surface C' through the lens 11b, whereby the image is formed only in the central portion (b). Part of the light is radiated to the portion (c) other than the image region in the photoreceptor surface C' through the passage clearance for light formed between the stationary shield body B and moving shield body 11a, whereby destaticizing is accomplished and the noncharging state is assumed. Hence, the portion (c) other than the image region is prevented from becoming solid black and the burden of the cleaning member decreases.

Title: Cleaning device
Inventor: OGATA HARUKI
IPC: B60S3/04
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a mechanism allowing opening and closing of a water channel by one-handed operation near a spout. SOLUTION: In this cleaning device, a water stop part 40 has a push rod 42 formed of a passage hole 42C, and a link allowing reciprocation of the push rod 42. When the push rod 42 is pushed up by a finger of one hand gripping a brush part 20 in the state that washing water is spouted from a spout of the brush part 20, the passage hole 42C is moved away from a passage hole 44A of the link to close a hose path and stop the spouting of the washing water. When the push rod 42 is pushed down, the passage hole 42C corresponds to the passage hole 44B to open the hose path and spout the washing water from the spout.  Because the hose path is opened and closed by the one-handed operation, i.e., only the pushing operation of the push rod 42 of a grip part 20A, waste of the washing water is prevented to realize water saving, and the operation is easy so as to improve usability, as compared to the case of two-handed operation.
