Title: Camera with motor-driven shutter
Inventor: HIRAI TOSHIAKI
IPC: G03B9/10
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent fogging of a film caused by a fault and to automatically return a camera to a normal state, when the cause of the fault is eliminated. SOLUTION: In this camera, the number of times the abnormality is judged by a recheck executed when a sector does not exist at a prescribed position in the case that a power source switch 41 is turned on, is counted and the action of a shutter is set in an disable state when the counted value exceeds the prescribed number. In the case that the sector exists at the prescribed position, when the switch 41 is turned on or it is judged at the recheck that the sector exists at the prescribed position, a shutter mechanism is actuated in accordance with the action of a release switch 44. Thus, since the action of the shutter is set in the impossible state when the serious abnormality is caused, the film is prevented from being wasted.  The temporary abnormality can be distinguished from the fault because the camera is returned to the normal state again when the cause of the abnormality is eliminated. Moreover, since the action of the release switch is not received when the sector does not exist at the prescribed position even if the switch 41 is turned on, the failures in photographing are eliminated.

Inventor: HASEGAWA KENZO
IPC: G02F1/133
Filed: 1999-03-15
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal projector and a lamp unit in which the lighting period of the lamp can be easily known and the operational load on a user is decreased. SOLUTION: The liquid crystal projector to modulate the light emitted from a lamp 3 by a liquid crystal and to project and display is provided with a lamp unit 1 equipped with the lamp 3 and a memory 5 to memorize the lighting period of the lamp 3 as detachable. The lighting time of the lamp 3 recorded in the memory 5 is visibly recognized and can not be initialized.

Title: Infrared detector
Inventor: TOMOYASU KUNIHIRO
IPC: G01J5/02
Filed: 1995-03-27
Abstract: PURPOSE: To lower power consumption by providing a space between a cold finger and an inner cylinder to reduce the load of a refrigerating machine. CONSTITUTION: Cold heat is generated at the tip end part of a cold finger 11 by a refrigerating machine 7 to cool an infrared detector 1 through a disc 3 contacting the tip part of the cold finger 11. An air layer between the cold finger 11 and an inner cylinder 4 has a spacer 13 buried thereinto. As a result, the air layer between the cold finger 11 and the inner cylinder 4 checks air convection generated owing to a temperature difference between air near the disc 3 and that near a flange 12. No warm air near the flange 12 is carried near the disc 3 to reduce heat infiltrated into the infrared detector 1 through the disc 3. Thus, the load is limited in the cooling of the infrared detector 1 down to a low temperature, for example, to 77K with the refrigerating machine 7 thereby making possible the lowering of the power consumption of the refrigerating machine 7.

Abstract: PURPOSE:To enable eccentricity tracing of a pipe by removing effect on a beveled surface at the end of the pipe, by installing photoelectric element for beveled surface position detection, controlling circuit means, and gate circuit means. CONSTITUTION:An output signal 22 of an amplifier 21 from the time of receiving irradiating laser beam by a beveled surface position detecting photoelectric element 20 up to suspension of the beam is compared with the specified value V1 by a comparator 23. While the signal 22 exceeds the specified value V1, an output signal 24 of the comparator 23 assumes a change of condition from L to H. And, the instant when the output signal 24 changed from H to L is detected by using a reflected beam of light which scanned running over an end of a pipe. Further, while the irradiating laser beam scans the beveled surface, controlling signals 15, 17 are stopped by controlling signal gate circuits 27, 29. By this, a faulty action of the controlling circuit due to abnormal reflection at the time when the beveled surface of the pipe is scanned can be prevented.
