Title: Charge transfer type solid-state image pickup device
Inventor: KADOTA TOKUZO
IPC: H04N5/359
Filed: 1989-08-18
Abstract: PURPOSE:To prevent drooping on a reproduced picture even when a high brightness object is image picked up by providing a substrate voltage control circuit increasing the substrate voltage of a solid-state image pickup element based on an output signal of a high brightness signal detection circuit. CONSTITUTION:When a high brightness signal is included in a signal output of a CCD 1, a detection signal is outputted from a high brightness signal detection circuit 3 for the time width and an output voltage of a substrate voltage control circuit 4, that is, the substrate voltage of the CCD 1 is switched tentatively to a comparatively higher voltage from a comparatively lower usual voltage. Since the upper limit of the signal output is suppressed for the CCD because the substrate voltage is increased, even when a high brightness object is picked up, the charge transfer capacity of the CCD is not exceeded. Thus, the generation of drooping in a reproduced picture is prevented and the CCD substrate voltage at the image pickup in the usual luminous quantity is kept to a comparatively lower value similarly to the case of a conventional device, then a sufficiently wide dynamic range is usually ensured.

Abstract: PURPOSE: To reduce the number of the stopping and inspection times of a device and to improve working rate by performing a correction process adjusting the light quantity of a light emitting element several times so as to make the output of an image density sensor detecting the quantity of stuck developer on an image carrier constant. CONSTITUTION: During the period of the warm-up of a fixing unit 160, the light emitting diode of the image density sensor DS1 is light-emitted and the density in a state where toner does not stick on the image carrier 110 is detected, and the output voltage of a variable DC power source is fixed by adjusting the output voltage of a density detecting circuit 520 at this time. A similar process is performed on the image density sensor DS2 . Then, the latent image of a maximum density correcting test patch is written on the image carrier 110, and a change in the maximum density of a copy image is corrected, and furthermore gradation is corrected.  In the case that the emitted light quantity is not decided at the time of deciding the emitted light quantity of the light emitting element of the image density sensors DS1 and DS2 so as to make sensor output constant, the same action is repeated several times, and after continuing an abnormal state several times, the device is stopped for the first time.

IPC: B21B39/16
Filed: 1989-08-22
Abstract: PURPOSE:To manufacture an H-shaped steel with small deviation of web center and high accuracy by connecting an eccentric sleeve to roll shafts of horizontal rolls through a bearing. CONSTITUTION:In the interface of the horizontal rolls 1a and vertical rolls 1b which are arranged in an universal rolling mill 1, the minimum clearance between rolls that is needed when sections are rolled is t1 and the clearance of t2 is formed between the horizontal rolls la and covers 12a which are provided on roll chocks 12.

IPC: H04N9/77
Filed: 1988-08-29
Abstract: PURPOSE:To prevent the deterioration of a color signal by outputting a pulse signal for a prescribed time from a horizontal synchronizing signal subject to synchronizing separation from a Y signal till the end of the back porch and selecting a notch filter to be incorporated into the circuit eliminating a C signal frequency band component superimposed on the Y signal by the time of the pulse signal.

Since the C signal frequency band component superimposed on the Y signal for the period of the SW pulse is regarded to be an undesired noise, a resistor R3, a coil L1 and a capacitor C1 of the notch filter are turned on by a TR 3. Thus, the Y signal to be mixed from which noise is eliminated is obtained.

Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a wafer detection mechanism in which the wafer can be prevented from being left in a container by reading out the longitudinal tilt on the wafer contained in the container, e.g. a carrier. SOLUTION: The wafer detection mechanism comprises a light emitting element 11 for irradiating a carrier C with a light beam L in elevating/lowering thereof, and a photodetector 12 disposed in the rear of the carrier C to receive the light beam L from the light emitting element 11, wherein a wafer W is detected based on the quantity of light received by the photodetector 12 which varies as the carrier C is elevated or lowered. A comparator 16 compares the quantities of light received before and after the wafer W traverses the light beam, based on the voltage values. An tilting direction decision unit 17 makes a decision that the wafer W is rising forward if the quantity of light received immediately before traversing the light beam is larger than the quantity of light received immediately after traversing the light beam otherwise makes a decision that the wafer W is falling forward.  Furthermore the position for inserting the pincette 31 of a wafer transfer mechanism 30 is corrected while taking account of the decision results of the tilting direction decision unit 17.

Title: Rotational frequency controller for diesel engine
Inventor: KIZAKI KANJI
IPC: F02D45/00
Filed: 1987-08-28
Abstract: PURPOSE:To enable an engine to be prevented from stall due to undershoot by renewing the accumulated value of correction amount when the rotational speed of engine is judged lower than the lower limit one except in idling. CONSTITUTION:A judging means in an electronic controller 60 judges whether or not the rotational speed of an engine 2 except in idling is lower than the lower limit of desired idle rotational speed minus a predetermined value. When the rotational speed of engine 2 is judged lower than the lower limit of rotational speed by the judging means, an accumulated value renewing means adds the accumulated value of correction amount obtained repeatedly on the basis of a difference between actual rotational speed detected by a rotational speed sensor 25 and desired idle rotational speed or lower limit of rotational speed to the accumulated value of correction amount obtained by an idle rotational speed controlling means to renew the value. Thus, the minimum value of rotational speed of engine can be maintained in the proximity of desired rotational speed even except in idling.
