Title: Keyboard device
Inventor: TANAKA HIDEO
IPC: H01H13/70
Filed: 1992-05-29
Abstract: PURPOSE:To enable maintenance before the unit fails completely by recognizing the abnormality when the number of generating chatterings reaches a certain value during one key depression time. CONSTITUTION:A scan signal output means applies scan signal to one contact of a key switch 3a corresponding to all keys 3 in 20ms cycle. When the specific key 3 is depressed in this state, a return signal is outputted from the other contact of the key switch 3a corresponding to the key 3. The number of pulses of a scan signal during one key depression time is compared with the number of pulses of a return signal by a comparing means. When the return signal is one pulse, the state is recognized as 'abnormal' (chattering generation) state, '1' is added to a counter. When the count value exceeds the limit value, the abnormality is recognized. Since the recognition of abnormality is displayed by means of a display lamp or the like, the maintenance is enabled before the unit fails completely.

Title: Method and optical component for uniforming luminous flux
Inventor: OOISHI NORIJI
IPC: G02B5/02
Filed: 1989-06-02
Abstract: PURPOSE:To obtain high-efficient, uniform luminous flux by uniforming light intensity without spoiling beam property. CONSTITUTION:Adjacent beltlike reflecting surfaces A and B shift in an X-axial direction by a distance (d), but beltlike reflecting surfaces of different X coordinates are arrayed in a Z-axial direction to constitute the entire reflecting surface. For simplification, the beltlike reflecting surfaces are arranged to equal width (t) much smaller than the Z-axial width of incident luminous flux and the S-directional intensity distributions of light beams incident on the surfaces A and B are substantially equalized to each other. Here, when the incident luminous flux 25 has a light quantity distribution, the light quantity distributions of reflected light beams on the surfaces A and B are shown by IA and IS. The incident light beam is not completely parallel light, but divergent in the Z-axial direction, so the light beams are mixed as they travel away from the reflecting surfaces. Consequently, the reflected light is uniformed like I.
