Title: Vibration control device having toggle mechanism
Inventor: ISHIMARU TATSUJI
IPC: E04H9/02
Filed: 1996-12-06
Abstract: PROBLEM TO BE SOLVED: To produce a damping effect in a small earthquake without producing bending stresses on a frame by enabling a device to be efficiently placed without being affected by the size of the frame. SOLUTION: When a frame 16 is displaced by 61 in the rightward direction, a short brace 23 and a long brace 27 make rotational movements about respective rotation bearings 20, 24, so that the amount δ2 of displacement of a rotary friction damper 28 is amplified and made greater than the amount δ1 of horizontal displacement of the rotation bearing 20 of an upper-story beam 14A. Small horizontal displacement of the rotation bearing 20 is amplified into large displacement of the rotary friction damper 28, establishing the relation that small displacement multiplied by a large force equals large displacement multiplied by a small force. The vibration of the frame 16 is damped by a small rotary frictional force generated at the rotary friction damper 28, and small vibration of a building caused by medium and small earthquakes and wind as well as by a strong earthquake is effectively damped. Also, since the angle θ1 which the long brace 27 and a lower-story beam 14B form is small, no extra bending stresses are produced on the lower-story beam 14B.

Title: Reflection type projection screen
Inventor: OSHIMA ISAO
IPC: G03B21/60
Filed: 1989-12-20
Abstract: PURPOSE:To prevent the lowering of contrast regardless of the projecting direction of external light by arraying and disposing many fine reflection mirrors provided with recessed part whose central part is depressed at large ratio with respect to the width of a peripheral part. CONSTITUTION:A projected light beam 4 is projected from a direction perpendicular to a screen and a projected light beam 41 is projected from an oblique direction. The projected light beams 4 and 41 are reflected by the fine concave mirror 3 or 31. Since a main light beam returns toward a projector, the distribution of luminous intensity is intense in the direction toward the projector and diffused light is properly obtained in a direction other than the direction toward the projector. The concave surfaces of the mirrors 3 and 31 are formed by depressing the central part at the comparatively large ratio with respect to the width of the peripheral part. Then, the reflected light of the projected light beam is allowed to have directivity, so that the effect to the above distribution of the luminous intensity is enhanced and the reflected light can be returned to a viewer side. Thus, a bright and high-contrast video is viewed in a bright room.

Title: Cassette loading device
Inventor: YOSHII TETSUJI
IPC: G11B15/675
Filed: 1990-11-27
Abstract: PURPOSE:To allow the use of two kinds of tape cassettes varying in the position and shape of the engaging recessed part of cassette loading by providing a tape cassette pull-in member provided toward the main surface of the tape cassette and a shift member for the tape cassette withdrawing pawl provided off a moving locus. CONSTITUTION:The compact cassette pull-in pawl 12 and the new cassette pull-in pawl 14 are both so supported as to act in a biting direction at the time of engagement, the former by a turning shaft 13 and the latter by a turning shaft 15. The new cassette pull-in pawl 14 is released from the outward shifting state by the shift member when the new cassette is successively inserted into a cassette holder 1 by positioning its sliding cap on the right side and its engaging recessed part on the upper side. This pawl is then projected upward toward the front surface of the new cassette by the energizing force of a leaf spring 20 and pulls in the engaging part 23 by engaging this part with the engaging recessed part. There is no engaging recessed part corresponding to the new cassette pull-in pawl 14 and, therefore, if the compact cassette is similarly successively inserted into the holder by positioning its opening on the right side, pull-in pawl is dropped to engage in the biting direction by the arrival of the corresponding engaging recessed part, i.e. the insertion hole of a reel driving shaft. The use of the two tape cassettes varying in specifications is possible in this way.

Title: Data processor for chromatograph
Inventor: KAMISAKA ITARU
IPC: G01N30/86
Filed: 1991-12-13
Abstract: PURPOSE:To appropriately decide the optimum peak detecting sensitivity in a short time by measuring and storing noise levels of all of mass numbers to be measured and deciding the peak detecting sensitivity of all the mass numbers to be measured from the average peak detecting sensitivity of several representative ions and stored contents. CONSTITUTION:A computer 2 measures and stores 6 in advance the average noise level of all of mass numbers to be measured in all the sections. Then the computer 2 finds the average peak detecting sensitivity by measuring the average noise level of mass numbers to be measured in the first section. The computer 2 successively finds the peak detecting sensitivity which is required for the current measurement from each mass number to be measured by correcting and converting the peak detecting sensitivity based on stored contents about noise level. As a result, the optimum peak detecting sensitivity is found for detecting the best peaking starting and ending points. Since the optimum peak detecting sensitivity is found for all the ion mass numbers by measuring the noise levels of several ions by one time only, the time required for deciding the optimum peak detecting sensitivity can be remarkably reduced and the analyzing process can be smoothly carried out.
