Title: Optical recorder
Inventor: MATSUBARA KEN
IPC: B41J2/445
Filed: 1989-04-14
Abstract: PURPOSE:To apply the optimum driving voltage to an optical shutter by applying the driving voltage according to an applied voltage detected when the surface potential of a photosensitive body become lowest. CONSTITUTION:A voltage which varies periodically within a necessary range including the suitable driving voltage is applied from a varying voltage applying means 20 to some optical shutters in an optical shutter array to drive the optical shutters with various voltages, and a surface potential measuring means 30 measures the surface potential of the exposed photosensitive body. An applied voltage detecting means 40 detects the applied voltage of the varying voltage applying means 20 when the surface potential of the photosensitive body becomes lowest and the driving voltage applying means 20 applies the best driving voltage to the optical shutters according to the detected applied voltage. Consequently, when the optical shutters are driven with the best driving voltage, the driving voltage need not be determined by measuring the state of light emitted by a light source, the spectral sensitivity of the photosensitive body, etc., at each time.

Filed: 1997-04-14
Abstract: PROBLEM TO BE SOLVED: To provide a motor control circuit where the downsizing and simplification of a circuit are possible by sharing the parts sharable for normal and reverse rotation. SOLUTION: At normal rotation, when a switch SW is turned on toward normal rotation side (connected in upward direction), voltage is applied to the base of Q12 through D11, R1, and R13, and by Q12 being turned on, a current flows from a terminal A to D12, R12, Q12, and a motor M, and a terminal B, and the motor M starts normal rotation. When the rotation of the motor M is locked, the current applied to the motor M increases, and the voltage across a current detecting resistor R2 goes up, and Q11 is turned on, and Q12 is turned off, and the current application to the motor M is stopped. By the same constitution, it detects the rotation of the motor M having locked, using the current detecting resistor R2 also at reverse rotation.

Title: Camera equipped with focus detecting device
Inventor: HAMADA MASATAKA
IPC: G02B7/28
Filed: 1987-04-16
Abstract: PURPOSE:To attain the release of a shutter even if the detection of focus is impossible or the quantity of defocusing is large in a consecutive photographing mode by permitting the release without executing the adjustment of a lens when the detection of focus is impossible or the quantity of defocusing is large at current photographing time and focusing is obtained at previous releasing time. CONSTITUTION:When it is decided that the delay in following occurs to an object based on the quantities of defocusing D5 and D6 at the point P1 in the midst of stopping the lens, the correction of following is executed at the point P1 by means of the computation C6 at the time of integration I6 and the correction is executed at the point P1 by supposing the movement of the object from the integration I6 to the middle point of the integration I8 through the integration I7. But, if a driving counted value to which a correction value is added in the midst of a following mode is larger than a previously specified counted value, the correction in following is not executed, if it overtakes on the way and a driving direction is inverted based on the computed result. Thus, in the consecutive photographing mode even when a camera is in an AF preferential mode, the release of the shutter can be possible even if focusing is not completed.

Abstract: PURPOSE:To recognize a fusion welding quality with a high precision and to manufacture coke of good quality at an inexpensive cost, by evaluating a fusion welding quality of each coal from vitrenit and ecdynit content rate of each unit coal for coke starting material and an O content by an element analysis value. CONSTITUTION:As vitrinite and exinite content rate of each unit coal for coke starting material increases, caking property increases, meanwhile, even if each coal equalizes in vitrinite and exinite content rate, it varies in a caking property with an O content. Therefore, the vitrinite and exinite content rate of each coal, being the analysis result of organization component obtained by JIS M8816, is measured. Meanwhile, an element analysis of each coal is conducted by JIS M8813, and a value, which is obtained through substraction of percentage of C, H, N, conbustible S, and ash from 100%, is found as the O content. Using a graph showing a relation between said two component contents and the O content and a relation of the caking property, the caking property of the starting stock coal is evaluated with a high precision, and this permits determining of a mixture ratio so that coke of good quality can be obtained even if a mixing amount of an expensive coking coal reduces.
