Title: Self-diagnostic method for angular speed sensor
Inventor: MITAMURA TAKESHI
IPC: G01C19/56
Filed: 1996-02-14
Abstract: PROBLEM TO BE SOLVED: To self-diagnose the vibration system of an angular speed sensor by driving a vibratory mass for a predetermined time and measuring the damping vibration of vibratory mass after stopping the driving. SOLUTION: In an angular speed sensor for detecting Coriolis force being generated in the direction of second axis of an orthogonal coordinate system when a vibratory mass is driven in the first axial direction and an angular speed is applied about the third axis, the vibratory mass is driven for a predetermined time and the damping vibration thereof is measured after stopping the driving thus self-diagnosing the vibration system of an angular speed sensor. Consequently, the amplitude and frequency of vibration system can be calculated. For example, the vibration frequency can be determined by measuring the generation time interval of zero-displacement point of vibration mass and the zero-displacement point can be determined based on the output from a C-V converter when the vibratory mass is stopped.  Relation between the damping constant and natural angular speed at the time of no damping can be determined from the measurements of vibration frequency.

Title: Picture density control method
Inventor: TOKUHASHI MASAKI
IPC: G03G15/08
Filed: 1990-02-07
Abstract: PURPOSE:To obtain a picture having a proper density corresponding to a picture notch etc., at that time by detecting the density of a developed toner picture by means of an optical sensor, detecting change in the density of a ground surface from the result of the detection, and correcting and controlling a capac ity for development according to the change in the density of the ground surface. CONSTITUTION:An electrostatic latent image of a ground surface pattern image is formed on a photosensitive body 1 by exposing ground surface pattern 19 of a low density provided independently of a reference density pattern 18, and the latent image is developed. Then, the optical sensor 17 detects the density of the developed toner picture, so that change in the density of the ground surface, such as soiling of the ground or rise in the potential of the ground, is detected. Based on the change in the density of the ground, obtained from the result of the detection, a capacity for development, such as exposure, is corrected. For example, when the density is shifted to the dark direction, it is controlled to the light direction. Thus, a picture having a density free of notch deviation, which corresponds to the picture quality notch at the time, is obtained.

Title: Analog waveform indication system
Inventor: TAKAHASHI YASUYUKI
IPC: G09G1/16
Filed: 1982-02-24
Abstract: PURPOSE:To achieve a higher speed of the indication by specifying the waveform indication point when a quantization data indicating the vertical position of a CRT housed in a memory coincides with a line number value calculated from scan lines covered by the CRT in comparison thereof. CONSTITUTION:A quantization data Ai of an analog waveform (each data corresponds to each dot of the CRT) is inputted and memorized into a refresh memory 2. Then, each of the data Ai is read out to match it with the timing of a clock generated with a clock generator section 3 and compared with a line number Bi of the scan line with a comparator 7. When Ai=Bi, a signal is outputted from an output terminal of the comparator 7 to the CRT for dot indication. The calculation of the line number Bi is done by subtracting the value of the number of scan lines with a counter 5 from a reference value Si of a register 4. This enables the fast indication of an analog waveform in real time.
