Abstract: PURPOSE:To conduct solid growth at fast speed, and to obtain a single crystal Si film having a large area by forming an insulating film onto a single crystal Si layer except the top face and side face of a projecting section in the single crystal Si layer, shaping an a-Si film onto the insulating film and annealing and treating the a-Si film. CONSTITUTION:A resist 2 is formed in order to shape a projecting section 11 as a seed crystal onto a single crystal Si substrate 1, and the substrate 1 is etched in an anisotropic manner to form the projecting section 11. The substrate is thermally oxidized, and an SiO2 film 3 as an insulating film is shaped on the whole surface. The surface of the projecting section 11 in the substrate 1 is exposed. An amorphous silicon film 4 is formed on a section from which the SiO2 film 3 is exposed and on the SiO2 film 3. The silicon film 4 is annealed and treated, and changed into a single crystal. Accordingly, solid growth is effected at fast speed, and a single crystal Si film 4' having a large area is acquired.

Abstract: PROBLEM TO BE SOLVED: To improve an image state which the human eye perceives by applying first and second transformation functions to a luminance value and a saturation value within the finite range of a color image and transforming them so that they correspond to a whole dynamic range. SOLUTION: The color image is expressed again by multiplex picture elements showing the whole range of the luminance value and the saturation value in a hue, saturation and luminance (HSV) space. The luminance value of the image is transformed by using a sectional linear mapping function 102 and the like for the luminance component for the color picture. A second transformation number decided by giving an extension procedure to a saturation histogram showing the saturation component of an original picture is applied to the saturation component and the saturation value is transformed. Then, enhancement for putting saturation and luminance to both ends of an area is executed without mixing the distortion of colors and the optimum picture is obtained.

Title: Telephone set provided with charging terminal
Inventor: HAMAZAWA YOSHINORI
IPC: H04M19/08
Filed: 1994-01-25
Abstract: PURPOSE:To provide a telephone set provided with charging terminals which effectively use loop current flowing during a call by compensating supply voltage to a transformer with a constant voltage diode and restricting supply current to an external load with a current restriction resistance. CONSTITUTION:When a telephone line 1 is closed at the time of the call by off-hooking, signal current flows in a diode bridge circuit 3 through an input terminal 2. The signal current is branched into the constant voltage diode 4 and the current restriction resistance 5 from the positive electrode-side 3a of the circuit 3. Then, it is supplied to one terminal 6a through the resistance 5 and is supplied to the primary-side 7a of the coupling transformer 7 and the other terminal 6b. Then, current flows into a charging battery 10 connected to the terminals 6a and 6b and the battery 10 is charged. Thus, a part of loop current circulating from the circuit 3 to the circuit 3 again through the primary- side 7a of the transformer 7 can effectively be used without a trouble in the transmission of the signal, and the battery 10 can effectively be charged with such constitution.

Title: Battery backup circuit for semiconductor storage device
Inventor: TAKANO MAKOTO
IPC: G06F1/26
Filed: 1986-01-17
Abstract: PURPOSE:To hold data stably by controlling the operation, which sets a selecting signal supplied to a semiconductor storage device to the non-operating level, and the operation which fixes the level of an address signal line by a level fixing means while shifting timings of these operations from each other. CONSTITUTION:When a detection signal phis from a supply voltage detecting circuit 3 is set to the low level, a control signal phi1 supplied from a control circuit 6 to a control signal generating circuit 2 is set to the operating level, and the inverse of a chip select signal CS is set to the high level synchronously, and a constituting part M1 of an SRAM is made non-operated. Since the control circuit 6 incorporates a time counting means, a delay means, etc., an address signal AL is forcibly set to the low level after the detection signal phis is set to the low level. Since the timing of the rise to the high level of the inverse of the chip select signal CS and that of a control signal phi0 are shifted from each other, the burden of a system power source for the operation of this rise, especially, the burden on the way of drop of the supply voltage in the process of switching to a battery backup is relaxed. Thus, data in memory cells is held stably.
