Title: Automatic focusing device
Inventor: HOSOE MITSUYA
IPC: G02B7/28
Filed: 1981-01-16
Abstract: PURPOSE:To prevent a hunting action at a point near a lens focus, by varying the drive control speed of an optical system in accordance with the storing time of the picture signal of a storage effect type photoelectric transducer. CONSTITUTION:The voltage corresponding to the storing time of a storage effect type solid state image pickup element is supplied to a terminal 203' and then applied to the base of a transistor (TR)228. The current flowing through the TR228 is controlled to give a slow speed to the rotation of an automatic focusing motor 222 in case the storing time is long. As a result, a lens shifts also in a low speed. When the storing time is short, the current flowing to the TR228 increases to give the rotation to the motor 222 in a high speed. Thus the lens shifts in a high speed. In such a way, the focusing speed of the lens is varied according to the duration of the storing time. Thus a hunting action can be prevented at a point near a lens focus.

Abstract: PURPOSE:To provide an inexpensive small-sized image forming apparatus not requiring a high voltage power supply or AC power supply and capable of forming a sharp image by mounting a toner feed belt arranged so as to be subjected to friction vibration at the part where a toner supply means is opposed to an aperture. CONSTITUTION:A toner supply device 20 is constituted so that the belt 24 held between drive and supply rollers 22, 23 comes into contact with a rod shaped support 25 under pressure. Toner 26 is rubbed with the belt 24 wound around the drive roller 22 from the supply roller 23 and positively charged to be supported on the belt 24. The supported toner 26 is formed into a thin layer by a layer prescribing blade 27 to be fed to the vicinity of the support 25 by the drive roller 22.

Title: Camber-shape measuring method
Inventor: TAIRA UTARO
IPC: G01B21/20
Filed: 1988-01-13
Abstract: PURPOSE:To continue distance measurement even if (r) pieces of all sensors do not cover a material to be conveyed and to make it possible to measure the shapes of both side surfaces along the approximately entire section, by obtaining a functional shape, which represents the shape of the side surface at the side, where only one sensor is arranged. CONSTITUTION:A planar body to be conveyed 1, which is a material to be measured, is conveyed by the rotations of table rollers 6, which are fixed to rails 5a and 5b. On the rails 5a and 5b, (r) pieces of distance sensors S1-Sr and one piece of a distance sensor Sr+1 are arranged. Thus the camber shapes of both side surfaces of the planar body 1 are measured. At this time, in addition to functional shapes, which represent the shape of the side surface at the side of (r) pieces of the sensors, a functional shape, which represents the shape of the side surface at the side of only one sensor, is obtained. The measured distance values are obtained at timing when some of (r) pieces of the sensors are deviated from the planar body 1. The amount of movement of the planar body 1 in the direction of the width and the amount of oscillation of the body are obtained at that timing so that each measured distance value optimally corresponds to the functional shape of the side surface on each side, which is obtained beforehand. Corrections for removing the effects of the movement in the axial direction and the oscillation are applied to the measured distance values of all the sensors, which are not deviated from the planar body 1 at this timing by using the obtained result.

Abstract: PURPOSE:To enable to effect a good proportional combustion within a wide range by a method wherein a ratio of fuel to air is varied with a predetermined period and the varying degree of flame electric current is computed to decide and control the ratio of fuel to air. CONSTITUTION:when a signal varying the ratio of fuel to air with a predetermined period is outputted from a moudulating circuit 16, a fuel feeding device 5 increases the amount of fuel through an adder 18. The fuel is changed into premixture by a proportional premixer 4 and is burnt in the burner 1. The burning condition is  monitored by a flame electric current detecting circuit 11. The flame current is inputted to an operating circuit 15 through an A/D converter 14 to compute the varying degree thereof and in case the condition is in an insufficient air combustion condition, the excess amount of the fuel is reduced by a subtracting circuit SUB and is outputted into the adding circuit 18. On the other hand, when it is in an excess air combustion condition, the insufficient amount of the fuel is outputted to the adder 18 by an adder ADD. According to this method, the combustion is brought into a point where the flame current is maximum and the most proper combustion condition may be obtained.
