Title: Cleaning device
Inventor: ISHIZU HISAO
IPC: G03G21/10
Filed: 1986-12-26
Abstract: PURPOSE:To perfectly execute cleaning by a blade, by constituting the titled device by bending both ends in the direction orthogonal to the moving direction of a photosensitive body in the blade, in the direction reverse to the moving direction of said photosensitive body, at the slide-contact position of said blade. CONSTITUTION:A blade 6b is formed by a flexible member having high wear resistance, stuck to the lower face of a horizontal piece of a holder 6a, and formed integrally with the holder 6a. Also, as for the blade 6b, length of its longitudinal direction is determined so as to become the same as that of the holder 6a, and both ends in a longitudinal direction are bent and inclined so as to be aligned with the shape of the holder 6a. Accordingly, when the blade 6b is pressed against the peripheral surface of a photosensitive drum 1, both ends in the longitudinal direction of the blade 6b are dragged and turned up in the same way as a conventional one by the rotation of the photosensitive drum 1. However, the blade is bent by the anticipation of its turn-up quantity, therefore, floating from the peripheral surface of the photosensitive drum 1 is suppressed, and the blade 6b becomes roughly flat extending over the whole area in the longitudinal direction. In such a way, the deterioration of the cleaning property can be prevented.

Title: Coordinate input device
Inventor: KAMONO TAKESHI
IPC: G06F3/03
Filed: 1990-11-19
Abstract: PURPOSE:To enable accurate coordinate detection by setting a comparison level so that variation in the detection timing of a transmission time due to the variation of an electric signal generated by converting the vibration of a coordinate indicator is minimized. CONSTITUTION:A vibration wave signal detected by a vibration sensor 101 passes through an analog switch 103, is processed by the absolute value conversion of an absolute value circuit 104, and passes through an LPF 105 to detect its envelope signal. The transmission time is detected in the vicinity of the inflection point of an envelope signal corresponding to the zero-cross point of the signal generated by differentiating the envelope signal twice by a differentiation circuit 106. For the accurate determination of this detection timing, the comparison level of a comparison level setting circuit 110 is varied to decides the comparison level, with which the variation width of the transmission time with the signal level becomes minimum, as the best value. Consequently, variation in the transmission time with the vibration wave signal level at the time of coordinate input can be suppressed with the simple constitution and the accurate coordinate detection is attained.

Title: Switching regulator
Inventor: IKEUCHI YASUHIDE
IPC: H02M3/155
Filed: 1990-11-16
Abstract: PURPOSE:To suppress the heat generation of a switching transistor by providing it with a frequency detection circuit, which detects the oscillation abnormality of the oscillated frequency of an oscillating circuit, and a switching circuit, which sets the level of an LC filter high. CONSTITUTION:If abnormal oscillation occurs, a frequency detection circuit P outputs the detection signal on low level, which shows oscillation abnormality, whereby the transistor Q1 of a switching circuit U becomes off. Thereupon, the output voltage Vout to a load F is added to a comparison circuit M through a resistor R1 without being divided by the resistor R2 of the switch circuit U and a transistor Q1, and the input voltage of the comparative circuit M becomes higher than the previous condition. As a result, the period when the input voltage V is larger than reference voltage Vk becomes long, and further the output cycle on high level of a control signal becomes longer. Thereupon, the output cycle of the driving signal being outputted from a driving circuit J according to this also becomes longer, and the heat generation of the switching transistor Q0 is suppressed.
