Filed: 1993-05-06
Abstract: PURPOSE:To obtain an easy-to-view display device excellent in operability by providing a display unit so that it can be attached/detached at the front surface covering position of a viewer or it can be moved near the viewer. CONSTITUTION:This device is provided with the display unit 31 displaying the negative image or the positive image of film F and the viewer 32 by which the film image is viewed directly or indirectly through reflection by a mirror. The display unit 31 can be attached/detached at the front surface covering the position of the viewer 32 or can be moved near the viewer 32 from the front surface covering position of the viewer 32. Therefore, a luminous flux from a light source passes through a printing lens 24 and irradiates the negative film F, then the image of the negative film F passes through a lens 32a and is totally reflected by a glass 32d to be projected to a screen 32c. When the display unit 31 is moved to the front surface of the viewer 32 because it is allowed to slide, the display of the viewer 32 is intercepted, thereby switching to the display unit 31 from the display of the viewer 32 without changing viewing angle.

Accordingly, the exchange signal ϕCTL is a signal which becomes logic 'high' under an active state and becomes logic 'low' under a stand-by state.  Thereby, this circuit is operated by the first current path iC1 suppressing a current amount under the stand-by state, while this circuit can be operated by the second current path which can obtain a sufficient current amount when required. Therefore, an attempt is made to reduce more a power than usual.

Title: Fault part retrieval system
Inventor: SAKURAI MIKIRO
IPC: H04L12/42
Filed: 1993-04-09
Abstract: PURPOSE:To specify a fault part in short time when an intermittent fault occurs. CONSTITUTION:A test signal is transmitted to a device 3 through signal lines S1 and S2 with a device 1 as a specified device, for example. The device 3 identifies the normality of the transmitted test signal. When it is normal, the test signal is returned to the specified device through S3 and S4 as it is. When it is abnormal, the test signal is corrected to a regular signal pattern. The corrected test signal and a received abnormality display signal are returned to the specified device 1 through S3 and S4. The specified device 1 judges that the fault part exists on the side of S3 and S4 (S1 and S2) when the returned test signal is 'abnormal' (normal) and the received abnormality display signal is 'absent' (present). When the fault part is judged to exist on the side of the signal lines S1 and S2, for example, the specified device 1 transmits the test signal to the device 2 through S1. The fault part is specified by repeating the operation.
