Abstract: A plane diffraction grating based on surface normal rotation according to the present invention is designed so that the profile of the grooves at a radial area is determined depending on a rotational position of the area about a rotational center defined as a foot of the rotational axis on the surface of the plane diffraction grating. An optical system such as a spectrometer or a monochromator according to the present invention uses such a plane diffraction grating, and requires a special arrangement. The optical system includes: a plane diffraction grating as described above; a mechanism for rotating the plane diffraction grating about the rotational axis; an incidence optical system for casting a converging beam of light on a point of the surface of the plane diffraction grating, where the point is set apart from the rotational center.

Abstract: A vibrator that produces bending vibration with both ends unsupported is mounted on one principal surface of a mounting board, and a driving-and-detecting circuit component is also mounted to cross over an antinode center line of bending vibration of the mounting board due to resonance. The original self-resonance frequency of bending vibration of the mounting board itself is lower than the frequency of bending vibration of the vibrator. The modified self-resonance frequency of bending vibration of the mounting board when the vibrator and the driving-and-detecting circuit component are mounted thereon is higher than the original self-resonance frequency, and does not coincide with the frequency of bending vibration of the vibrator.

Abstract: A theft-prevention ink pack device is provided, comprising a support member (70) having support lugs (73a, 74a, 75a, 75b) within a case (130) having ink spouts (66) and knife edges (69) , a tray member (80) supported by the lugs (73a, etc.) , spaced from the knife edges (69) , an ink pack (90) placed on the tray member (80) and having a bag (92) containing ink (91), a pressboard (100) positioned behind the ink pack (90), and conical compression coil springs (120, 121) for pushing the pressboard (100). When the support member (70) is moved as it is pulled, the support provided by the support lugs (73a, etc.) of the tray member (80) is cancelled to cause the tray member (80) to fall down and the ink pack (90) is broken by the knife edges (69) and urged under pressure by the spring forces of the springs (120, 121) via the pressboard (100) to cause the ink to spurt through the ink spouts (66).

Abstract: In order to provide a vibrating gyroscope in which variations in the angular-velocity detection sensitivity are not likely to occur even when sharp temperature changes occur, a vibrator for a vibrating gyroscope includes, on one main surface, a first detection electrode and a second detection electrode, which output a signal containing an angular-velocity signal, wherein a groove having a predetermined depth is provided between the first detection electrode and the second detection electrode. As for a vibrator for a vibrating gyroscope of the present invention, since the difference between the resonance frequency and the anti-resonance frequency in a bending vibration mode in the driving direction becomes closer to the difference between the resonance frequency and the anti-resonance frequency in a bending vibration mode in the detection direction, variations in the angular-velocity detection sensitivity are not likely to occur even when sharp temperature changes are given.

Abstract: The present invention provides a piezoelectric vibrator, in which there is no significant change in the characteristics even when depole occurs due to heat shock and the like. The piezoelectric vibrator includes a first piezoelectric substrate having split electrodes formed on one main surface thereof and a second piezoelectric substrate having a common electrode formed on one main surface thereof. The remaining main surfaces of both piezoelectric substrates are bonded to each other via an intermediate electrode. The material of the first piezoelectric substrate differs from the material of the second piezoelectric substrate. As a result, the difference (longitudinal DF) between a resonant frequency and an anti-resonant frequency in a longitudinal vibration of the piezoelectric vibrator substantially coincides with the difference (transverse DF) between a resonant frequency and an anti-resonant frequency in a transverse vibration thereof.

Abstract: A leaf transfer mechanism unit, to be incorporated in general in an automatic teller machine, defines a leaf reception room between a pickup roller and a partition member. Behind the partition member, a leaf delivery room is defined between the partition member and a retrieval urging member. When the retrieval urging member is allowed to move forward within the limit of a front limit position, bills received in the leaf delivery room can be urged against the pickup roller. During this operation, the partition member is kept at a turnout position beyond the front limit position of the retrieval urging member. The pickup roller is exposed behind the partition member. Since the turnout position can be defined at the extension of the path of movement for the retrieval urging member, it is possible to avoid the partition member at the turnout position from largely and remarkably protruding out of the path of movement.
