Title: Method and device for automatic focus and zoom adjustment of projector
Inventor: HOO KEN KOO
IPC: G03B21/53
Filed: 1995-04-24
Abstract: PURPOSE: To adjust the focus and zoom of the projector neither manually nor manual operation through remote control. CONSTITUTION: A recognition pattern is projected on a screen and the luminance of the recognition pattern is measured by a detection sensor 7 to calculate a contrast value; and the variation of the focus value of a projection lens and the calculation of the contrast value are repeated until the contrast value becomes maximum. When the contrast value becomes maximum, it is judged whether or not the recognition pattern is projected on the screen at a maximum, and when not, the zoom value of the projection lens is varied and the adjusting operation is redone from the calculation of the contrast value where the luminance of the recognition pattern is measured and ended when the recognition pattern is projected on the screen at its maximum.

Title: Main spindle device for machine tool
IPC: B23B31/117
Filed: 1992-03-25
Abstract: PURPOSE:To prevent generation of vibration at the time of the high speed rotation of a main shaft by using as a conical spring to energize a drawbar what is composed of a flat circular plate portion and a conical portion at its outer periphery and is formed with a specific taper surface on the inner surface of its penetration hole. CONSTITUTION:A thing which is composed of a flat circular plate portion 11a and a conical portion 11b at its outer periphery, and on the inner surface of whose penetration hole that is formed at the center, a cylindrical surface 11c on the conical portion 11b side and a taper surface 11d whose inner diameter increases from the cylindrical surface 11c toward the opposite side, are formed, is used as a conical spring 11 to energize a drawbar 7. When axial push-pressing force is made to act upon the conical spring 11 and deformation is conducted, the diameter of the penetration hole inner surface hardly dwindles, and on account of this, it is possible to set a clearance between the penetration hole inner surface of the conical spring 11 and the outer surface of the drawbar 7 extremely small, and the generation of vibration when a main shaft is rotated at a high speed is prevented and noise can be restrained.

Title: Ultrasonic flaw detector
Inventor: UCHIDA KUNIHARU
IPC: G01N29/26
Filed: 1982-06-09
Abstract: PURPOSE:To display a picture with high precision and to improve the ability to plot the reflection source position of a material to be detected, by finding the deflection angle and transmission and reception points of an ultrasonic-wave main beam by making corrections according to a preset focusing distance and a preset deflection angle. CONSTITUTION:The timing of a delay trigger signal output for transmitting and receiving an ultrasonic wave is so set that the ultrasonic-wave beam 2 is transmitted and received at an angle theta from a nearly center point C of the transmitting and receiving vibrator group of an array type flaw detector 1, focusing the ultrasonic-wave beam 2 on a point F of the material 3 to be detected. This time timing is set in a transmission delay setter 11 and a reception delay setter 14. The main beam direction to the point F, however, is the direction of the bisecting angle of an angle gamma containing the array type probe 1 from the point F, so a point A on the array type probe 1 is the transmission and reception point of the main beam. The beam deflection angle is psi different from theta. For this purpose, the distance AC between the points A and C and the angle psi are calculated to obtain the starting point and sweep direction of a picture sweep on a B scope display 18. Then, a signal processor 17 corrects the ultrasonic-wave beam 2 according to the set focusing distance l and set deflection angle theta.

Abstract: PROBLEM TO BE SOLVED: To provide a method for forming the mask pattern of a mask in which a pattern correction calculating time can be shortened, and an influence due to a light proximity effect can be precisely suppressed by suppressing the deterioration of the through-put of drawing. SOLUTION: In a mask pattern forming method at the time of forming a mask for an optical lithography by electron beam drawing, an exposure process by an electron beam is constituted of a first exposure process for operating exposure with constant exposure to the whole area of a pattern area 10, and a second exposure process for operating exposure with prescribed exposure to prescribed areas 100a-100d including edges 10a-10d. Thus, the correction of a light proximity effect in optical lithography can be precisely operated, and the deterioration of the through-put of pattern drawing can be suppressed by using the mask in which the mask pattern is formed.

Filed: 1988-04-22
Abstract: PURPOSE:To simply display the latest data by deleting the segment having the oldest LRU (least recently used) attribute and registering a new segment in case a segment whose LRU attribute is designated exceeds the LRU attribute capacity designated previously at the registration of the segment. CONSTITUTION:A graphic processing part 12 permits each segment used for graphic display to decide whether it can own its LRU attribute or not. Then the part 12 interprets and processes said decision. An LRU attribute segment control table 18 forms a table which stores the information on the production order of segments having their designated LRU attributes. A segment control processing part 15 checks via a capacity checking part 16 whether a working segment exceeds the set value of an LRU attribute capacity memory part 14 or not at registration of the segments having their designated LRU attributes. In case a new segment to be registered exceeds the set attribute capacity, the oldest segment is deleted and the new segment is registered by reference to the table 18.

Then when the car washing machine body is retreated to wash the upper surface of the vehicle with the upper brush 3, the operation time of the car washing machine body in response to its position is computed by a control unit 14 every unit time according to the retreat time of the car washing machine body, so that the arm of the upper brush 3 is vertically driven while the stored locus data are aimed at as target values. Thus, each rotational angle of the upper brush and the arm become approximately less than the half of their conventional ones, so that the car washing machine body can be miniaturized.
