Title: Dc regenerating circuit
Inventor: OGI KEISUKE
IPC: H03M13/00
Filed: 1985-01-29
Abstract: PURPOSE:To prevent the influence of a data error in case of a dropout by inhibiting a clock from being sent by a PLL circuit in a dropout period and holding the DC level of the output of an LPF equal to the level before the dropout occurrence. CONSTITUTION:The PLL circuit 4 extracts timing from a playback signal (b) and generates a clock (d) which is in optimum phase in an eye pattern. The playback signal (b), on the other hand, is inputted to a discriminating circuit 3. The discriminating circuit 3 compares this playback signal (b) with a specific threshold value and converts the playback signal (b) into binary data output C with the clock (d) from the PLL circuit 4 according to the large/small relation. A dropout in the playback signal of the discriminating circuit 3 is detected by a dropout detecting circuit 7, whose detection output is inputted to an AND gate 6 to inhibit the clock (d) from the PLL circuit 4, and consequently the output (e) of a level detecting circuit 2 and the low-frequency component output (f) of the LPF5 are held in the dropout period, so that the DC level at the start of the dropout is estimated as the current DC level at the end of the dropout.

IPC: G01B7/00
Filed: 1992-01-29
Abstract: PURPOSE:To enhance the bond properties of surface plating layer for avoiding the demagnetization of a magnet body due to corrosion by a method wherein a magnet material powder with the particle surface thereof coated with copper is sintered. CONSTITUTION:A Cu layer 8 is formed by plating step on Fe-31Cr-23Co magnetic particles 7. Next, the magnet particles 7 coated with Cu after being blended and kneaded with a binder are impressed with a magnetic field so as to manufacture a molded body comprising the magnet particles 12 oriented in one direction inside a mold 10. Next, this molded body slowly heated in non- oxidized atmosphere with the binder removed while sustaining the heated temperature is hot isotropically compressed in argon gas atmosphere to manufacture a less porous sintered body. Through these procedures, the bond properties of a plating layer can be enhanced requiring of no underneath processing step when the corrosion preventive metal plating step is performed. Furthermore, the demagnetization of the magnet body due to corrosion can be avoided.

Title: Switching regulator
Inventor: KOIZUMI AKIO
IPC: H02M3/28
Filed: 1979-02-08
Abstract: PURPOSE: To improve the regulation of a switching regulator and simplify the constitution of the regulator by providing a tertiary winding in a transformer and varying an electric current flowing through the tertiary winding in response to the variation of the load current.  
     CONSTITUTION: When an electric current flowing through a secondary winding 5b is increased, the voltages across the secondary and tertiary windings 5b and 5c of a transformer 5 are accordingly raised to thus raise a spike voltage. Since the current flowing through the tertiary winding 5c is also increased at this time, the difference between the load voltage of thefirst smoothing circuit 10 and the detected voltage at the output terminal P of the second smoothing circuit 41 becomes low to improve  the regulation of a switching regulator.

IPC: H03L7/14
Filed: 1979-02-09
Abstract: PURPOSE:To prevent the disturbance of phase, by performing the phase control continuously with the continuous input of input signal, stopping the phase control when the input signal is off, and keeping the voltage controlled oscillator to the state immediately before the input interruption. CONSTITUTION:The phase control loop is constituted with the phase comparator PD4, LPF2 and voltage controlled oscillator VCO3, and the input signal interruption detection circuit 5 and the external control processing circuit 6 are constituted with monostable multivibrators.

If the next pulse is not incoming after the coming of input pulse, the hold is released. Taking the external control signal 04 as logic 1, as far as the input signal 01 is inputted, phase control operation is made. When the signal 01 is absent, the output of the circuits 5, 6 is logic 0 and the phase comparison inhibit signal 08 is also 0, the circuit 4 is not operated, the phase control is stopped, VCO3 keeps the oscillation phase immediately before the input signal interruption, no phase disturbance is caused.

Title: Solid-state image-pickup device
Inventor: ISHIDA TAKAYOSHI
IPC: H04N5/378
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To display a satisfactory screen, even if excessive light is made incident on a solid-state image-pickup element and black level fluctuates by changing the phase of a horizontal transfer pulse at a part of the horizontal period of the solid-state image-pickup element, generating and clamping the signal of a level, which is almost equal to a black level and controlling the exposure of the solid-state image-pickup element with the level of the clamped signal as a reference. SOLUTION: An OB clamping circuit 3 clamps an OB signal from the solid- state image-pickup element CCD1 and generates the black level. A video signal processing part 7 executes various video processings, based on the black level and outputs a video signal. On the other hand, a pseudo-OB clamping circuit 5 inverts the phase of the horizontal transfer pulse with respect to a reset pulse, generates the pseudo-OB signal which is almost equal to the black level as output from CCD1 and clamps it. An exposure control part 9 controls exposure based on the level of the pseudo-OB signal. Thus, exposure is controlled, even if excessive light is made incident on CCD1, and appropriate video signal processing can be executed.

Inventor: XU ZHENG
IPC: C23C14/35
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To perform sputtering deposition of a layer for increasing the coverage of both a side wall part and a bottom part by sputtering an aluminum layer with a relatively high purity for forming a wet layer before depositing a metal contact layer. SOLUTION: A target material that is sputtered and is ionized is then attracted toward a substrate that is in negative potential to attract an ionized deposition material toward the substrate. A wet lower layer 404 such as aluminum alloy is deposited in an opening 400 that is located in an oxide layer 402 of the substrate. To increase the amount of material entering the opening 400, aluminum alloy that is sputtered from a target is preferably ionized by plasma in a chamber. The side wall covering of the lower layer 404 is improved by sputtering aluminum with a relatively high purity, preferably with at least a purity of 99.9% and further preferably a purity of 99.999% to form a wet layer.

Title: Air purifier
Inventor: UEDA TAKAO

Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To form an air purifier in a state not damaging the indoor appearance and the purifying efficiency and to hold an air ejecting unit in a stable state. SOLUTION: An air stream toward the slant upward direction is ejected from an air ejecting unit 4 installed on a floor toward a roof-shaped sucking unit 3. Since an air curtain is formed by the air stream from the ejecting unit 4, contaminated air can be efficiently sucked and purified. The appearance is not damaged even though it is installed in the room, because the depth of the air ejecting unit 4 is small. The air ejecting unit 4 is stabilized by connecting the air electing unit 4 with the air sucking unit 3 with a pipe-like connection member 5, and also the cord is treated beautifully by penetrating the cord into the connection member 5.

Abstract: PROBLEM TO BE SOLVED: To reproduce multi-level images having high quality while recording interference fringes as binary images on a medium. SOLUTION: Many computation points are defined at 2 μm pitch in the longitudinal and transverse directions on a recording surface by defining an original picture, recording surface and reference light. The intensity of the interference waves formed by the object light emitted from the original image and the reference light is computed with respect to the individual computation points. The binary patterns D0 to D4 defined by dividing a unit region consisting of a square shape of 2 μm per side to a first region having a pixel value 'white' and a second region having a pixel value 'black' are defined in five ways by changing the occupying rate (0 to 100%) of the first region. The binary patterns having the occupying rate corresponding to the interference wave intensity with respect to the respective computation points are allocated, to obtain the binary images.  The binary images are plotted on the medium by electron beams and the computer hologram medium having recessed parts and projecting parts is formed.
