Title: Phase locked loop circuit
Inventor: NAGOYA TETSUO
IPC: H03L7/18
Filed: 1985-02-19
Abstract: PURPOSE:To keep the phase and output frequency of a VCO in dropout occurring period to a phase and frequency just before the generation of dropout by fixing an output of a phase comparison means to the condition where the LPF output of the next stage is unchanged. CONSTITUTION:Resistors 16, 18, a capacitor 19 and resistors 20, 21 and a capacitor 22 constitute an LPF at the inverting and non-inverting side of an operational amplifier 17 and charge pump function is provided by combining the LPFs with a phase comparison circuit. Further, a varactor diode 26, an inductor 27 and an oscillation circuit 28 constitute a VCO. When the timing with a dropout detection signal SD at high level is caused with input signals 11, 12 both at low level, both output signals 01, 02 of the circuit 31 have a glidge due to gate delay and keep a high level. Then the output of the LPF having the charge pump function is kept to a voltage level just before dropout occurrence. Thus, the output frequency and phase of the VCO are kept to those just before occurrence of dropout.

Title: Optical fiber thermometer
Inventor: YAMADA TAKEO
IPC: G01J5/08
Filed: 1993-01-28
Abstract: PURPOSE:To improve durability of an optical fiber used as temperature sensor with respect to high temperature. CONSTITUTION:Quartz optical fiber covered with a non-combustible polyimide resin is used as optical fiber 5 utilized as a temperature detection end and a waveguide. The polyimide resin covered with the quartz optical fiber sublimates if held at a high temperature and is kept from undergoing a stress to prevent the lowering of the transmissivity of light as caused by a microbending. The optical fiber 5 is covered with an acid resisting fireproof alloy to achieve higher durability with respect to a high temperature, which can prevent the roughing of the surface of a metal pipe 6 as caused when the optical fiber is held at a high temperature for a long time. In addition, as the surface of the metal pipe 6 will not rough when held at a high temperature, fusing or fastening will not occur between the optical fiber 5 and the metal pipe 6. This enables the prevention of disconnection of the optical fiber owing to a difference in the coefficient of thermal expansion between the optical fiber 5 and the metal pipe 6.

Title: Image processing method
Inventor: FUJIMOTO YOSHIICHI
IPC: H04N1/40
Filed: 1995-01-26
Abstract: PURPOSE: To perform the image processing of compressed data without expanding them by applying a symmetric transformation to the pixel blocks of a U-V coordinate system that underwent the discrete cosine transformation after a compressed image is decoded and then applying the symmetric transformation to the entire image to code it after the array of blocks is changed. CONSTITUTION: The compressed image data stored in a main memory 26 undergo the entropy decoding via a CPU 20 and also undergo the color conversion processing such as the thinning of color components which are unnecessary for visual recognition. Then the processed data undergo the discrete cosine transformation(DCT) and are transformed into a U-V coordinate system by a soft processing that is carried out by the CPU 20 based on a coefficient block symmetric transformation means 42. Then the positive and negative DCT coefficients of the U-V coordinate system are transformed as necessary for every pixel block and also undergo the symmetric processing including the rotation around the U-V axes.  Then a block position conversion means 44 applies the symmetric processing to the entire image data in the same way, and the image data are coded based on the JPEG standard and stored in a magnetic disk 26. In such a way, the compressed data can be quickly and easily undergo the image processing with no expansion.

Abstract: PURPOSE:To form an impurity diffused layer having a shallow junction by forming a polycrystalline high melting point metal silicide layer on a single crystal substrate at low temperature, and then heat treating it to grow the silicide grains. CONSTITUTION:A W silicide thin film 2 which contains, for example, phosphorus is formed on a single crystal silicon substrate 1. When the substrate is then heat treated, the grains of the W silicide 3 are grown, phosphorus impurity passes the grain boundary to be diffused at high speed and distributed in high density on the surface of the single crystal silicon. The impurity phosphorus atoms accumulated on the surface are slightly diffused in the silicon to form a high density phosphorus shallow diffused layer 4. Thus, the silicide layer to become a diffusion source is accumu lated by containing the impurity in the silicide by CVD or sputtering, the grains of the silicide is grown by heat treating to sweep the impurity existing in the grain boundary to diffuse the impurity in the semiconductor substrate. Accordingly, no defect is formed in the semiconductor single crystal. A high density shallow impurity diffused layer is formed in a region having small diffusion coefficient in the substrate by the thermal diffusion by selecting the temperature and the time of growing the grains of the silicide.

IPC: H01F41/02
Filed: 1979-03-22
Abstract: PURPOSE:To enable smooth winding, by providing drive rollers inside and outside a wound core and applying turning forces to the core from both sides to wind the core around a leg of a coil. CONSTITUTION:After a wound core 3 previously shaped and wound is arranged on an inside drive roller 4, the end of the outermost layer 8 of the wound core is passed inside a leg 6a of a coil 5 and tentatively fixed on a part X of the outermost layer. Another drive roller 2 and a guide pole 9 are provided in contact with the outside of the circular outermost layer 8. As a result, the core 3 is maintained in the form of a prescrived circle by the driving roller 2 and the guide poles 9, 5. When the rollers 2, 4 are rotated in the direction of an arrow, the core 3 is revolved in the direction of another arrow so that all the core is finally rewound inside the circle. After that, the roller 2 and the pole 5 are removed and the tentative fixation X is eliminated. The entire rewound core 3 is compressed from its outermost layer 8. As a result, the steel band is wound around the leg 6a by the elasticity of the band, which acts to return the band to the form of the previously shaped wound core.

Filed: 1979-03-22
Abstract: PURPOSE:To accelerate decarburization and produce the extra low carbon steel in a short time by top-spouting the jet of the mixed gases of oxygen and inert gas after the blowing by pure oxygen. CONSTITUTION:Pure oxygen gas is blown in a reduced-pressure atmosphere. When the C content in molten steel becomes around 0.1%, the gases mixed with 50% of inert gas (Ar+N2 or N2) are top-blown. Furter at the end period of blowing where the C content becomes around 0.01%, the jet of the mixed gases of inert gas: O2 gas=75:25 are top-spouted to perform blowing, whereby the product is obtained. Namely, O2 and mixed gases are blown under a vacuum to accelerate the stirruing and diffusion in the molten steel simultaneously and at the same time expand the effective reaction interface on the gas side. As a result of this, the extra low-carbon steel may be produced at the rate of decarburization which is practically the same as that in conventional methods.

Title: Stator for permanent magnet step motor
Inventor: IDA OSAMU
IPC: H02K37/14
Filed: 1994-03-02
Abstract: PURPOSE:To obtain a highly reliable stator by partially bending the top surface or bottom surface of a coil bobbin and permitting to start winding at a point of different inner diameter thereby preventing generation of noise. CONSTITUTION:In the stator of a step motor, the top surface 11 of a coil bobbin is partially cut open and then it is bent to form a new wall 12 so that winding of a magnet wire can be started thereat. When the winding amount of magnet wire is small, an air gap is produced on the outer periphery of coil bobbin and the heat in the air gap causes to deform the top and bottom surface parts of the coil bobbin. When the top or bottom surface of coil bobbin is cut open and bent to form a new wall surface for starting the winding of magnet wire, the magnet wire can be embedded up to a part very close to the outer periphery of the coil bobbin. Consequently, thermal deformation is suppressed at the top and bottom parts of coil bobbin and backlash of the stator due to the air gap thereof can be suppressed.
