Title: Dx code easy detecting device
Inventor: YAMAGUCHI KOICHI
IPC: G03C3/00
Filed: 1988-12-23
Abstract: PURPOSE:To reduce the DX code detection space in a camera by detecting the condition state of the 3rd - 5th contacts of a DX code and deciding the ISO speed of a film. CONSTITUTION:The DX code 2 is added to a cartridge P and detection pins 3 - 5 of the camera are brought into contact with its DX3 - DX5, and the pins 3 and 4 are connected to input terminals P3 and P4 of a microcomputer 6 and the pin 5 is grounded. Then when the DX3 and DX5 are electrically conductive, it is decided that the ISO speed of the film in the cartridge P is 100 and when the DX4 and DX5 conduct, it is decided that the ISO speed is 400. Thus, the DX3- DX5 are used to eliminate an unnecessary space between the detection pins, thereby utilizing the space effectively.

Abstract: PURPOSE:To attain a high speed low power consumption circuit or ultrahigh speed circuit operation by making a current flowing to a PN junction diode in the standby state when an input voltage is at a low level coincident with that in the standby state when an input voltage is at a high level. CONSTITUTION:A current in the standby state sufficiently smaller than a current flowing in the operating state of the circuit is supplied from a power voltage terminal 3 to GND via a P-channel MOSFET 100, a PN junction diode 105, an N-channel MOSFET 101 and a PN junction diode 106. Thus, a forward voltage is generated across the diodes 105, 106 and the voltage is used to keep the base-emitter voltage in the standby state of bipolar TRs 103, 104 to a prescribed value and the steady-state current is fixed. Then the current flowing to the PN junction diode in the standby state when the input voltage is at a low level is made coincident with that in the standby state when the input voltage is at a high level. Thus, a high speed low power consumption circuit or an ultrahigh speed circuit operation is attained.

Abstract: PROBLEM TO BE SOLVED: To provide the subject mixer realizing the good mixing of air and a liquid to atomize the liquid to eject the same as fine particles. SOLUTION: A conical part 10 throttled in a downstream direction is formed to the downstream end of a cylindrical mixing chamber 9 and a gas-liquid passage 3a is connected to the conical part 10, and a liquid passage 4a arranged in coaxial relation to the gas-liquid passage 3a is allowed to face to the interior of the mixing chamber 9 to be opened toward the conical part 10 at its end part and an air passage 5a is connected to a ring-shaped space S formed outside the liquid passage 4a in the mixing chamber 9 to constitute a gas-liquid mixing type mixer 1.  By this constitution, water (liquid) flowing in the mixing chamber 9 from the liquid passage 4a is throttled by the flow along the conical part 10 of air (gas) flowing in the mixing chamber 9 from the air passage 5a and, therefore, a negative pressure area is generated in the central part of the flow of water and, since the negative pressure area involves the air flowing along the periphery of this area, water and air are well mixed and water is atomized by this mixing to be ejected as fine particles.

Abstract: PROBLEM TO BE SOLVED: To obtain an optical radar apparatus whose configuration is simplified by a condensing means is moved so as to be interlocked with the scanning operation with light for irradiation and reflected light is condensed nearly in the center of a light-receiving means irrespective of the direction of the scanning operation. SOLUTION: A light-receiving lens 14 is held by a guide roller 18 so as to be slidable in a direction at a right angle to the optical axis of the lens. A slider 22 is held so as to be slidable together with the guide roller 18.

When the rocking body 19 is rocked to the right with this configuration, the right side is irradiated with light, and its reflected light is returned from the right side. However, the light-receiving lens 14 is pushed by the rocking body 19 so as to be moved parallel to the right side, and the reflected light is condensed nearly in the center of a photodetector 15.  In the same manner, even when the rocking body 19 is rocked to the left side, the light-receiving lens 14 is moved to the left side, and reflected light is condensed nearly in the center of the photodetector 15. In this manner, the reflected light is always condensed in the center of the photodetector 15.
