Title: Image pickup optical system
Inventor: KIKUCHI TOSHIRO
IPC: G02B15/22
Filed: 1989-05-12
Abstract: PURPOSE:To properly adjust the quantity of light at the time of normal photographing and microphotographing and to reduce the size of a mechanism by arranging a material stop which has a light shield part whose maximum diameter is smaller than the maximum diameter of luminous flux capable of passing through a mechanical stop in an open state on an optical path nearby the mechanical stop. CONSTITUTION:In the image pickup optical system equipped with photographic lenses 1 and 2 and the mechanical stop, the material stop 4 which is variable in transmissivity with an electric field or magnetic field and a variable refractive index lens 5 as a liquid crystal lens are arranged nearby and behind the mechanical stop 3. In normal photography, light quantity adjustment and focusing are performed principally by the mechanical stop 3 and lens systems 1 and 2 and in microphotography, the light quantity adjustment and focusing are carried out principally by the material stop 4 and variable refractive index lens 5. The diameter (b) of the shield part 4a of the material stop 4 is smaller than the maximum diameter a0 of the mechanical stop 3 and a stop which is smaller than the minimum diameter a1 of the mechanical stop 3 is obtained by the material stop 4 in microphotography, so proper exposure and deep depth of field are obtained.

Title: Damp-proof and insulating mounting circuit board
Inventor: HAYAKAWA TAKESHI
IPC: H05K3/28
Filed: 1987-05-15
Abstract: PURPOSE:To improve moisture-proofness and insulating properties by applying an ester group coating agent to a substrate, each circuit part and a mounting circuit board. CONSTITUTION:The surfaces of a substrate 1 and circuit parts 2, 3, 7 are coated previously with an ester group coating agent 4. These circuit parts 2, 3, 7 are loaded onto the substrate 1, the whole surface is further coated with an ester group coating agent 4a, a damage inhibitor 6 is coated, and the whole surface is further coated with an ester group coating agent 4b from the upper section of the damage inhibitor 6, thus completing a mounting circuit board 5. Accordingly, when ester encounters moisture, ester absorbs the moisture and is decomposed (hydrolyzing) thus preventing the deterioration of insulating properties and moisture-proofness.

Title: Method for controlling memory access bus and its information processor
Inventor: SHIMURA AKIHIRO
IPC: G06F13/36
Filed: 1991-05-24
Abstract: PURPOSE:To enable access without special hardware by deciding a bus width at the time of accessing a CPU for a memory based on information about the access bus width of a exchangeable memory. CONSTITUTION:The bus width information set at the head part of an external memory 7 is read, the bus width is decided, and the value is set to a programmable bus width control circuit 8. This programmable bus width control circuit 8 outputs a bus width control signal 9 to a CPU 1, controlling the CPU 1 to access the external memory 7 by the decided bus width. Thus, the bus width, when the CPU 1 accesses the external memory 7 through the external memory interface circuit 6, is set, and the external memory 7 is accessed from the CPU 1 by the set bus width. Therefore, the CPU 1 can access the external memory 7 by the bus width according to the configuration of the external memory 7.

Title: Paper arranging device
Inventor: MOCHIZUKI AKIRA
IPC: B65H31/34
Filed: 1984-06-13
Abstract: PURPOSE:To produce proper carrying force in a paper arranging device of copier, by increasing/decreasing the rotation of motor with correspondence to the thickness of paper in tray thereby increasing/decreasing the centrifugal force functioning onto a paddle and maintaining the contacting pressure against the uppermost paper constant. CONSTITUTION:Upon increase of the number of paper A to increase the thickness of the paper, the rolling angle of an arm 9 will increase while the detected level of a potentiometer 10 will decrease to lower the supply voltage to D.C. motor 6 thereby the rotation of motor 6 will decrease to decrease the rotation of the rotary shaft 3 thus to reduce the centrifugal force functioning to a paddle 4 and to contract the paddle 4. When the thickness of paper is low, the rolling angle theta of the arm 9 will decrease while the detected level of the potentiometer 10 will increase to increase the supply voltage to the motor 6 thus to increase the rotation and to expand the paddle 4 through centrifugal force. Since the paddle 4 will contract with correspondence to the thickness of paper, the contacting pressure against the uppermost paper is maintained constant to produce proper carrying force.

Title: Picture processing unit
Inventor: SUGAWA HIROYA
IPC: H04N1/40
Filed: 1988-05-17
Abstract: PURPOSE:To automate the switching from the existing read mode into a binary read mode or an intermediate tone read mode by inserting identification paper between a series of originals and switching the mode into the read mode in response to the detection of identification paper. CONSTITUTION:A color detection means SE5 detects a series of original color supplied to a picture information read means by an automatic carrier supply means. With prescribed color identification paper inserted between a series of originals, a color discrimination section 42 discriminates the color and gives an input to a CPU via an ADF controller 41. In the input of a color discrimination signal, the CPU switches the read mode of the picture read means from the existing read mode into the binary read mode or the intermediate tone read mode automatically with respect to a series of originals in succession to the identification paper. Thus, when a series of originals consist of a character original and a photographic original, the switching of the read mode is applied automatically.

Filed: 1983-07-04
Abstract: PURPOSE:To prevent central segregation in a continuous casting bloom by stirring electromagnetically and continuously a molten steel from the place on a strand where V-segregation arises in the axial center of the bloom until the molten steel solidifies thoroughly. CONSTITUTION:The thickness dv of the solidified shell forming V-segregation in the axial center part of a bloom in the stage of producing the bloom with a continuous casting machine is determined by the equation such as dv=a/DELTAT-b.Vc +C.SW+d/DELTATLS (a, b, c, d are positive constants), etc. from the casting conditions such as the overheating degree DELTAT of a molten steel, casting speed Vc, cooling water ratio SW, the temp. different DELTATLS between the liquidus line and solidus line depending on the comps. of the steel, etc. The place on the strand where the solidification progresses to said thickness dv is determined and the molten steel is electromagnetically stirred substantially continuously after said place until the molten steel solidifies thoroughly. The defect in the axial center part such as central segregation of the continuous casting bloom is thus eliminated.

Abstract: PURPOSE:To obstruct the welding of a lubricant and a toner and to form stably a picture having a good quality by changing an opening area of an opening of a hopper, and always supplying a lubricant of an about constant quantity to a photosensitive body. CONSTITUTION:A pinion 13a provided on a driving source 13 such as a motor, etc. is meshed with a rack 6'a of a front plate for constituting a part of a hopper, and the pinion 13a displaces a rack 6a in the direction as indicated with two arrows B by a motion of the driving source 13. As a result, the excessive supply of the lubricant obstructed by reducing the width of a gap contacting a lubricant 2 directly to a photosensitive body between a sealing member 5 and a blade 3, and the supply of the lubricant of a necessary quantity is secured by widening gradually the gap width as the number of passing sheets goes on and enlarging the opening area of the hopper. The motion of the driving source 13 is executed by detecting the number of passing sheets and a revolving speed of the photosensitive body at every time when they reach a prescribed count, and driving the driving source concerned 13 for a prescribed time to be controlled by a CPU.

After roughly ground, the hot-rolled steel sheet is primarily cold-rolled with a rolling ratio of 75-80%, recrystallization-annealed, acid pickled and then condition-rolled without a lubricant with a rolling ratio of 0.5-5.0%. After condition-rolled, the steel sheet is finish cold-rolled with a  rolling ratio of 37-44%, recrystallization bright-annealed instead of conventional  recrystallization-annealing and acid-pickling, and then finally condition-rolled  without a lubricant. As a result, a ferritic stainless steel sheet excellent in workability, e.g. hole-expansibility and deep-drawability, and surface brightness is obtained.
