Title: Constituting method ror picture information service system
Inventor: SHIBATA YOUJI
IPC: H04N7/173
Filed: 1977-12-02
Abstract: PURPOSE: To reduce the traffic of a video signal outputted from a center by installing a character generator for input monitor information in a sub-center near a subscriber's terminal.  
     CONSTITUTION: In center 4, only picture sound file 1 is installed, and character generator 2 and change-over switch 3 usually in center 4 are provided into sub- center 9 installed near subscriber's terminal 11 via inter-office junction line 5 and repeater 6. A signal to be transmitted to subsrciver's terminal 11 is stored temporarily in picture sound buffer memory 7 of sub-center 9 from picture sound file 1 of center 4 and then, transmitted to subscriber's terminal 11 by way of switchboard 8 and repeater 6. A monitor picture signal such as a request signal by a key signal from terminal 11 is sent back to terminal 11 by character generator 2 of sub- center 9. The traffic of inter-office junction line 5 is therefore reduced as much as that.

Title: Signal processing system
Inventor: KITAGAWA SHIYUNJI
IPC: G06K7/00
Filed: 1981-09-11
Abstract: PURPOSE:To perform secure binary coding by decreasing the time constant of one of an upper and a lower evelope, formed from an input signal, when the other envelope has the same level with the original input signal, and controlling a slice level. CONSTITUTION:An original signal varying in level is amplified by an amplifier 1, whose output is supplied to upper and lower envelope generating circuits 2,  and and 2', comparators 3 and 3', and a slice level generating circuit 7. When  either of the comparators 3 and 3' detects the coincidence between the level of  one envelope and the level of the original signal, monostable multivibrators 4  and 4' are inverted in state, and time constant control circuits 5' and 5 decrease  the time constant of said lower or upper envelope. Those multivibrators 4 and 4'  are reset to their original states a specified time and the time constant is also  increased to its original value. While the time constant is small, the envelope  rises or falls in a steep curve. Consequently, a slice level which is the intermediate value between the upper and lower envelopes follows up the original  signal, thereby performing accurate binary coding.

Inventor: KURITA HIROYUKI
IPC: G02B27/10
Filed: 1992-06-04
Abstract: PURPOSE:To enable a interferometer to perform highly accurate measurement with a simple constitution by modulating the oscillating wavelength of a coherent light source by changing the inrush current to the light source and measuring the wavefront aberration of reflected light from a surface to be inspected by a phase shifting method or phase difference stepping method. CONSTITUTION:Laser light reflected by a spherical lens 13a and laser light reflected by a surface to be inspected 7a overlap upon another in a cubic beam splitter 4 and form interference fringes on an image pickup element 9 after passing through an image forming lens 8. A controller changes the oscillating wavelength of a semiconductor light source 16 by an amount suitable for a phase shifting method or phase difference stepping method by controlling the inrush current to the light source 16. The interference fringes formed on the element 9 are read in the order according to the phase shifting or phase difference stepping method and phase calculation is performed. When such a method is used, highly accurate measurement can be performed with a less number of parts, since no mechanical mobile section having a complicated mechanism is required.

Title: Editing system of pulse code modulation magnetic sound recorder
Inventor: SHINPO MASATOSHI
IPC: G11B20/10
Filed: 1980-10-15
Abstract: PURPOSE:To prevent generation of an abnormal sound at a connecting point, by gradually connecting a level difference at the connecting point, like delta modulation. CONSTITUTION:A difference of amplitude of two continuous sampling values (n), (n+1), which have been sampled by a sampling period and quantized and PCM- coded in the proximity of an editing connecting point detection control signal, is divided 64, 65 into polarity and absolute value information. Subsequently, a step DELTA which has been set in advance is compared 66 with a absolute value, and in case the absolute value is larger than DELTA, by its polarity, the step DELTA is added 69 to the sampling value (n) when the polarity is positive, and is subtracted 68 when it is negative, which is made the sample value (n+1). Also, when the absolute value is smaller than or equal to DELTA, the sampling value (n+1) is obtained by adding zero to the sampling value (n).

Title: Lateral semiconductor device
Inventor: TSUKUDA KIYOSHI
IPC: H01L29/73
Filed: 1977-12-05
Abstract: PURPOSE: To improve dielectric strength and a degree of integration by shaping thinly the plane of an impurity diffusion region constituting a lateral semiconductor device except an electrode fitting part and by making the minimum curvature redius at its quoin part approximately one and a half as much as the diffusion depth of a PN junction.  
     CONSTITUTION: The lateral PNP transistor is formed of P-type emitter region 5, N- type base region 8 and P-type collector region 6. In this constitution, the curvature radius of the PN junction quoin part between collector region 6 and base region 8 determining its dielectric strength is selected approximate one and a half as much as the depth of the junction in order to avoid electrostatic focusing. Further, although electrode fitting part 6a of collector region 6 is made wide enough to feed a current, part 6b except it is shaped in a line to reduce the area of its collector junction. As a result, since the collector-junction area is small, the junction electrostatic capacity becomes small, its dielectric strength improves, and the small area of island region 4 where regions 6 and 8 are provided is required, so that the degree of its integration will be improved.

Filed: 1990-06-01
Abstract: PURPOSE:To prevent an entire system-down by deciding the priority of control operation in advance based on each power consumption of plural electric devices so as to control the plural electric devices. CONSTITUTION:An in-rash current and a normal current of electric devices 31,32-3n which are energized are detected and the data is stored in a RAM 14 together with an address. When all the data is stored in the RAM 14, a priority decision section 2 decides the priority operating the electric devices 31,32-3n in the larger inrash current order. An arithmetic control section 12 receiving a control signal obtains the sum of the usual current by reading the data of an electric device in the ON state among the electric devices 31,32-3n from the RAM 14 and calculates a current margin from the total sum. Then the plural electric devices 31 (or 32-3n) being controlled systems of the control signal are controlled in the ON state sequentially based on the priority.

Abstract: PURPOSE:To simplify a power source by enabling a device to be driven with a power source of one-side polarity by setting leakage magnetic field from the position control mechanism of a magnetic head for magnetic field modulation to make follow the plane shaking of a disk equal to magnetic field strength at an erasure or recording side. CONSTITUTION:The magnetic head 31 for magnetic field modulation is driven and controlled so as to keep a distance to the recording film 12 of the magnetic head 31 constant by permitting a current to flow on a movable coil 45 corresponding to a position signal detected with a position detector 41. The driving mechanism is comprised in such a way that a magnetic circuit consisting of a permanent magnet 46 and a yoke 47 which generates DC magnetic field and arranged oppositely to the movable coil 45 performs recording and erasure by setting leakage DC magnetic field in a direction perpendicular to the recording plane 12 from the magnetic circuit equal to the magnetic field strength of modulation magnetic field at the erasure side or recording side. Since the DC magnetic field of the magnetic circuit for the position control of the magnetic head 31 is used as erasure magnetic field or recording magnetic field, overwrite can be performed by applying pulse magnetic field with one-side polarity from the magnetic head 31.
