Patent JP-H04147499-A (JP)
Title: Electric waveform measuring device
Inventor: KOISHI YU
IPC: G01R13/34
Filed: 1990-10-09
Abstract: PURPOSE:To measure a high speed electric signal even not in the case of a repetitive signal by extracting a charge at each point at a storage means with one ultrashort pulse light radiation by plural high speed optical operating switch means arranged along a transmission line and measuring plural points simultaneously a voltage in a prescribed timing of an electric signal to be measured propagated through the transmission line. CONSTITUTION:An electric signal to be measured inputted from an input terminal 13 to a transmission line 12 is sent at a transmission speed depending on the characteristic of the transmission line 12. While the electric signal to be measured is being sent to the transmission line 12, a light radiation means 20 use an ultrashort pulse light which irradiates optical operating switches 14A - 14L simultaneously synchronously with the transmission. Thus, the charge in the vicinity of the connection point between the optical operating switches 14A - 14L and the transmission line 12 is sent to storage means 16A - 16L connected to the optical operating switches 14A - 14L respectively. The quantity of charge stored in the storage means 16A - 16L is read by a read means 18. Thus, in the case of a high speed electric signal, an event that only a repetitive electric signal can be used for the measurement is avoided.

Title: Method for measuring dv/dt yield quantity of thyristor
Inventor: MATSUYAMA MITSUO
IPC: G01R31/26
Filed: 1984-12-26
Abstract: PURPOSE:To make it possible to stably measure the dv/dt yield quantity of a thyristor with high accuracy under high voltage, by using a light coupling element as an erroneous operation detection means. CONSTITUTION:When a thyristor 1 is ignited by a lamp voltage generator 2, an ion current flows because impedance is rapidly reduced from the characteristic aspect thereof and light is emitted from a light emitting diode D1 but a light receiving transistor Q1 is brought to an ON-state by said light. The change in output voltage V1 at this time is used as the erroneous operation detection information of the thyristor 1. Because information is transmitted by light coupling as mentioned above, the detection voltage of a logical circuit is obtained regardless of measured voltage of dv/dt yield quantity in a state electrically separated from a measuring system and high accurate and stable measurement can be performed.

Title: Automatic focusing circuit
Inventor: MURASHIMA HIROSHI
IPC: G02B7/36
Filed: 1986-11-17
Abstract: PURPOSE:To set a large threshold value for the restarting of the rough adjustment of the automatic focusing operation as a result of object variation detection and to minimize unnecessary automatic focusing operation by adjusting the automatic focusing operation roughly and finely independently by two control circuit. CONSTITUTION:The 1st focus motor control means 15 fixes a lens 1 at the maximum point where a focus evaluated value is maximum and stops a focus motor 3, and the 2nd focus motor control means 17 drives the focus motor 3 again to displace the lens 1 finely and confirm the gradient of the focus evaluated value intermittently, and adjusts the lens 1 finely so that the focus evaluated value is at the maximum point at all times. Then, the 1st focus motor control means 15 restarts down-hill operation when the correction quantity exceeds a specific value. Consequently, the lens does not vibrate at the time of focusing and never stops in an out-of-focus state. Further, peak confirmation is performed intermittently to eliminate the stopping of the lens in the out-of-focus state even if the subject distance varies, the threshold value for subject variation detection is set large, and unnecessary focusing operation is precluded.

Abstract: PURPOSE:To obtain an image forming device having the self-diagnostic function which can cope with abnormal states, by providing a means, which receives the overcurrent signal from a detecting means to cut off a power supply circuit of a rotating body driving means, and a rotation control means of a rotating body. CONSTITUTION:An abnormality detecting circuit detects the overcurrent to a motor 12 and the reverse rotation of the motor 12 as abnormality. The potential difference generated between both ends of a resistance 43 in accordance with the magnitude of the current is impressed across the emitter and the base of a transistor TR44, and the TR44 is turned on when its value exceeds a prescribed value. If the TR44 is turned on by the overcurrent, the collector output is changed from the low level to the high level, and this signal is inputted to a motor controlling CPU31d through a signal line 45 to detect the overcurrent. This overcurrent signal is sent to a relay 42 from an OR gate 46 through a buffer 47 to cut off the power supply circuit of the motor 12.
