Patent JP-S60254975-A (JP)
Title: Automatic mode switching circuit
Inventor: KAWASAKI MOTOAKI
IPC: H04N5/91
Filed: 1984-05-31
Abstract: PURPOSE:To perform stable operation even if an abnormal color signal is generated during the reproduction of VTR owing to an error in mode switching by performing switching between two modes, i.e. PAL-M mode and NTSC mode repeatedly while a color signal is abnormal, and setting the VTR in one mode fixedly when the color signal becomes normal. CONSTITUTION:Numbers of ID signal pulses are generated if a PAL/NTSC mode setting is mistaken, so this feature is utilized; a detector 2 detects a peak with ID signal pulses and an inverter 3 performs inversion, and then the output of the inverter 3 is ''H'' in normal mode and ''L'' in abnormal mode. When an astable multivibrator 7 oscillates at a frequency of about several Hz, the mode is abnormal in reproduction, so the output of an OR gate 4 is ''L'' and a switch 6 is on. Consequently, the mode drive output of a flip-flop 8 oscillates between ''H'' and ''L'' at the oscillation frequency of the multivibrator 7. Then, the mode goes to normal at ''H'' or ''L'', and then the output of the OR gate 4 is ''H'' and the switch 6 is off, fixing the normal mode.

Abstract: PURPOSE:To manufacture a semiconductor device including a buried impurity layer and having small leakage currents at low cost in a short time by forming a gettering layer at a position near to the buried impurity layer in depth deeper than the buried impurity layer. CONSTITUTION:An oxide film 4 in thickness of several hundred Angstrom is formed onto the surface of a silicon semiconductor substrate 1, and the ions of a fixed quantity of oxygen are implanted into the substrate 1 in depth of several mum through the film 4, thus forming a gettering layer 2, into which oxygen is implanted. When isolating oxide films 5 are shaped through selective thermal oxidation, secondary crystal defects as sinks for gettering are formed at a section, particularly the central section of the layer 2. The ions only of a fixed quantity of a conductivity type determining element are implanted to a position shallower than the layer 2 by high energy, thus forming a buried impurity layer 3. The layer 3 is activated through annealing for one hr at 1000 deg.C in a nitrogen atmosphere. The crystal defects based on ion implantation are absorbed to the layer 2, thus manufacturing a semiconductor device including the layer 3 and having small leakage currents at low cost in a short time.

Filed: 1981-07-20
Abstract: PURPOSE:To surely hold a disc, by moving a holding member to a disc loading position and a disc support position through the change of direction of electric power application to a coil.

Title: Discharge lamp lighting device
Inventor: IWABORI YUTAKA
IPC: H05B41/282
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To reduce stress on a switching element and an inductor element, while securing safe and speedy lighting of a discharge lamp. SOLUTION: When starting, a compensation signal Vd is inputted in an output adjusting signal generating circuit 6 from a second compensation signal forming circuit 9. A difference in the pulse width of an output adjusting signal Vs between a power source trough part and a power source crest part gets small, therefore modulation in a PWM control gets shallow, the duty of the output control signal Vs in the power source trough part decreases and the duty in the power source crest part is increases, in comparison with the vicinity of normal lighting. As a result, stress applied on switching elements Q1-Q4 and inductors L1-L2 due to an increase of the peak value of an output choke current iL2 in the wave crest part can be reduced.  When starting, even if a wave distortion in the output current increases a little, preference is given to suppressing the maximum value of a switching current, and stress applied on a circuit element such as a switching element can be reduce, by operating so as to form the output current in almost the same rectangular shape as the conventional case in the vicinity of the normal lighting.
