IPC: G03B27/54
Filed: 1988-01-08
Abstract: PURPOSE:To prolong the life of a light source lamp by diffusing the light of the light source at the time of recording an image. CONSTITUTION:One side 1-a, which is a glass surface,of a lighting lamp 1 is diffusing surface and the other side 1-b is transparent. In printing actions, the diffusing surface 1-a is set to a microfilm F side and light beams toward a photosensitive drum through a projection lens 5 is diffused so as to reduce the unevenness of light quantities in a center and a periphery. In case of the action of a reader, the transparent surface 1-b of the lamp 1 is set to the film F side through a lamp board 20 by rotating a knob 21 to increase the light quantity which reaches a screen, so that the image on the screen is made light enough to be easily read. Since it is unnecessary to make the lamp voltage of the light source excessive, the life of the lamp can be prolonged.

Title: Doppler radar apparatus
Inventor: YAMADA YOSHIFUMI
IPC: G01S13/50
Filed: 1982-01-11
Abstract: PURPOSE:To improve the field through depression capacity, the clutter inhibition capacity and anti-disturbing wave capacity by reducing the band with a narrow band pass filter used at the first stage with a voltage control oscillator handling a Doppler tracking. CONSTITUTION:A signal of frequency fo is generated with a transmitter 2 and radiated through an antenna 1. The signal received 7 gives fo+fd, that is, addition of a Doppler frequency fd to the frequency fo. A controller 14 allows a  voltage control oscillator 15 to operate at IF+fd so that a beat signal 8 provides a constant frequency IF. The output signal 16 of a mixer 12 turns to  fo+IF+fd and fed to a mixer 3. This makes the value IF of the frequency 8 of the beat signal 8 constant and a narrow band pass filter 13 is used at the first  stage to reduce the band of a receiver. Thus, an AGC amplifier 4 won't start  AGC at a noise level such as clutter and field through.

Filed: 1979-01-11
Abstract: PURPOSE: To prevent an operation error by giving an alarm of auto-power-OFF operation by an acoustic generator before the operation of the auto-power-OFF function of an electronic desk-top calculator.  
     CONSTITUTION: While an electronic desk-top calculator is in operation, switch 2 is ON to put an external power supply to work. As for timer circuit 4, output signal (d) of keyboard 6 serves as a reset signal and every time a key is pushed, the timer is reset to hold switch 2 ON by output (a) of the timer. Since signal (d) is not outputted when no key is depressed, the timer starts counting. Timer output (b) is activated before output (a) by setting and if no key would be pushed until the time before timer output (a) is activated, output (b) is activated to activate output Q of FF6, thereby driving external acoustic generator 7. Once an operator operates a key, output (c) resets FF5 to stop the generation of a sound. Even if the operation does not notice the generation of the sound, output (a) is activated to turn switch 2 OFF at the set time.
