Title: Illuminance unevenness compensating device of variable power copying machine
Inventor: KITA SHINJI
IPC: G03G15/04
Filed: 1982-09-06
Abstract: PURPOSE:To uniform the illuminance distribution on a photosensitive material surface by fixing a light shielding member between an original surface and a lens, and cutting off the end part of luminous flux incident to the lens according to magnification. CONSTITUTION:The lens 3 is moved closer to the original surface than a position B for unmagnification copying during enlargement and moved closer to a photosensitive surface 2 during reduction. The light shielding member 5 is set fixedly at a position O between the original 1 and lens 3 and the contour of the light transmission part of the light shielding member is so formed that luminous flux reflected by the circumferential part of the original 1 is cut at a specific rate as the magnification varies from enlargement to reduction. When an exposing means for providing original surface illuminance necessary for the maximum variable power, the reflected light from the original end part is cut by the light shielding member at a rate corresponding to the magnification to obtain uniform illuminance distribution on the photosensitive material surface 2. When the ratio of the necessary quantity of light of the circumferential part during the maximum variable power to the center quantity of light is amax and the ratio of the necessary quantity of the light of the circumferential part during magnification (x) to the center quantity of light is ax, the cutting rate l1 during the magnification (x) is represented by an equation 5x.

Title: Magnetic disk device
Inventor: SUZUKI MASAMI
IPC: G11B5/55
Filed: 1986-07-02
Abstract: PURPOSE:To obtain an actuator for a magnetic disk device with high speed and high precision by driving the actuator and regulating the position of the center of gravity or the center position of a driving force in such a way that an oscillation which is generated then becomes minimum. CONSTITUTION:For setting a dislocation DELTAr between the center of gravity G of the actuator and the point of application P of the driving force which abnormally deteriorates the precision of positioning, the bar 21 of a ferromagnetic body is inserted to the adequate depth of a through hole 20. A magnetic flux density on the under side of a magnetic gap 18 (around the through hole 20) increases and the force around is enlarged as the bar 21 is deeply inserted, whereby the point of application P of the driving force dislocates to the under side and the dislocation DELTAr becomes small. At such a time, a magnetic head 5 reproduces and demodulates a position signal recorded in a magnetic disk 10. As to a signal waveform, the oscillation amplitude of the signal waveform becomes small as the dislocation DELTAr becomes small and becomes smallest when DELTAr=0. Consequently, the insertion depth of the bar 21 is optimum at that time.

Title: Luminance control circuit in color picture display device
Inventor: INOUE HITOSHI
IPC: H04N9/72
Filed: 1985-07-15
Abstract: PURPOSE:To obtain a reproducing picture with high quality and easy to see by synthesizing three signals of R, G and B with a prescribed ratio to generate a Y (luminance) signal by supplying DC voltage corresponded to its average level to a luminance control terminal. CONSTITUTION:A voltage level VDC represented by a broken line is a voltage- divided bias voltage by resistors R6 and R7, and the bias is applied to the Y signal passed through a capacitor 8 by the bias voltage. At such a time, it is assumed that the high voltage part of the Y signal is a bright part, and the level is divided to a bright portion 21 and a dark portion 22 setting the bias voltage VDC as a boundary and the areas of both portions are equal. Therefore, when the Y signal is a dark signal, the voltage level of the dark portion 22 rises so as to approach the bias voltage VDC. On the other hand, while a pulse is supplied to the base of a transistor 9, the transistor 9 is conducted and a voltage level equivalent to the pedestal of the Y signal is transferred from a collector to an emitter and is supplied to the base of the next stage of transistor 10. Thereby, the transistor 10 charges a capacitor 11 and holds the voltage.

IPC: G05B7/02
Filed: 1990-06-13
Abstract: PURPOSE:To obtain the satisfactory controllability by giving a valve calculation opening degree corresponding to a new set value to a flow rate control valve at the time of changing a flow rate set value, and restarting the PID control at the time point when a deviation between a flow rate detection value and the new set value becomes a small quantity value. CONSTITUTION:At the time of changing a flow rate set value, the PID operation of a flow rate controller 8 is interrupted and its control output is not provided to a flow rate control valve 6, and instead thereof, a valve opening MVI signal corresponding to a new set value of a flow rate is applied to the control valve 6. The opening degree of the control valve 6 is fixed to the valve opening degree, and at the time point when a deviation between a flow rate detection value and the new set value becomes a prescribed small quantity value, the PID operation is restarted from the fixed valve opening. Also, since the control output is provided to the control valve 6, overshoot and hunting caused by this restart of the PID control are suppressed, and various constants of the PID operation being optimal to the constant value control can be selected, therefore, satisfactory controllability is obtained in both of the constant value control and the follow-up control.

Abstract: PURPOSE: To increase the radius of curvature of a junction surface and to effectively suppress current concentration at a PN junction periphery edge part by spreading the a diffusion region larger than a depth for a reference edge prescribed by an inner periphery edge at the surface side of the substrate of an opening. CONSTITUTION: A diffusion region 2 of a semiconductor element is spread to a substrate surface larger than a depth Yj for a reference edge 4c prescribed by an inner edge part at the side of a substrate 1 at a second opening part with a larger radius of curvature than the periphery edge part. That is, the diffusion region is formed so that Xj>=Yj can be established with the spread of the diffusion region in side direction from the reference edge 4c as Xj. The diffusion region 2 is formed so that it spread to the substrate surface larger than the depth for the reference edge 4c prescribed by a peripheral edge at the side of the substrate 1 of a second opening part 4b.  Further, the radius of curvature of the peripheral edge part of the junction surface for demarcating the diffusion region 2 is formed to have a larger value than the depth of the diffusion region 2, thus suppressing the current concentration at a part for forming the curved surface of the PN junction surface.

IPC: G06F21/12
Filed: 1995-06-21
Abstract: PURPOSE: To provide a system which enables ciphering and deciphering to be carried out with efficiency without a program being falsified. CONSTITUTION: Enciphered enciphering/deciphering processing programs Pr1, Pr2,... are transmitted from an information processing device to an IC card by an initial program IP when a password agrees, the IC card deciphers these programs with a deciphering key of a rightful user and sends them back. An information processing device disposes these programs in a work memory area PA, causes them to get started and carried out data enciphering/deciphering processing. Accordingly, these programs, being normally in an enciphered condition, are neither analized nor falsified by a third party. After the rightful user has completed data processing, the deciphered plain programs are erased so as not to leave room for the plain programs surviving after the processing, and security of these programs is thereby assured. Enciphering work can be carried out with efficiency without a need for work of taking a storage medium of these programs out of a deposit place and setting it in the information processing device.
