Filed: 1989-06-14
Abstract: PURPOSE:To quickly obtain a synchronizing signal by sampling the signal which is earlier activated between the signals sampled by a synchronizing clock signal and the signal sampled with the inverted value of the former signal. CONSTITUTION:An AND circuit 5 is changed to a low level from a high level by the signal which is earlier changed to a low level from a high level (activated) between those output signals outputted from the output terminals of the FF 1 and 2. An FF 3 samples the output signal of the circuit 5 at the time of rising a synchronizing clock signal 101. Thus the FF 3 samples the output signal that is earlier changed to a low level from a high level (activated) between those output signals of the FF 1 and 2 at the time of rising the signal 101. As a result, this signal that is earlier changed is outputted by the FF 3 as a synchronizing signal 102.

Abstract: PURPOSE: To enable simple formation at a low cost, by controlling the scanning speed of a layered structure to a zone heating source, and moving a solid-liquid interface along a line stripe in such a manner that the surface of a substratum facing the solid-liquid interface is liquefied. CONSTITUTION: A thin polycrystalline or amorphous layer of semiconductor material is deposited on an insulating substratum whose softening temperature is low, and a layered structure is formed. Rectangular thin stripes of semiconductor material which are practically parallel are formed on the insulating substratum whose softening temperature is low. Thin stripes of the semiconductor material is heated with a zone heating source wherein heat is concentrated on the thin stripes, by using a method wherein a solid-liquid interface is formed along a plane of the thin stripes, and an angle which is at least 8 deg. to the axis of the thin stripes is formed. During the above processes, the substratum is heated at its annealing point, and a formed layered structure is scanned in a direction wherein a main axis of the thin stripes is in parallel to the zone heating source.  The solid-liquid interface is moved along the thin stripes in such a manner that the surface of the substratum which faces the solid-liquid interface is liquefied by controlling a scanning speed of the layered structure to the zone heating source. Thereby cost and complexity of an adopted equipment are reduced.

Title: Command transmitter and receiver
Inventor: TAKAGI HITOSHI
IPC: F41G7/30
Filed: 1988-06-21
Abstract: PURPOSE:To provide a receiver with a narrow band, prevent the deterioration of S/N and obtain a command transmitter and receiver having excellent receiving performance by synchronizing a local oscillator in the receiver with an oscillator in the transmitter before launching a missile. CONSTITUTION:A carrier signal 6 is inputted into a phase comparator 23 from the side of transmission through a connector 27 while phase synchronize is established in a local oscillator 21 by a phase synchronizing loop. In this case, a sample hold circuit 25 transmits the output of a loop filter 24 to a voltage control oscillator 22 as it is. The interlocking of the connecter 27 is released after launching a missile and one of inputs for the phase comparator 23 is eliminated whereby the phase synchronizing loop is opened. Further, a hold signal 26 is sent to the sample hold circuit 25 simultaneously with the launching and, therefore, a control voltage impressed on the voltage control oscillator 22 immediately before the launching is held. In a demodulator 19, deviation will never be generated between an inputting intermediate frequency signal 18 and a transmission side carrier frequency after the launching and, therefore, a receiver may be provided with a narrow band and, as a result, the deterioration of S/N ratio may be prevented.

Title: Magnetic fluid seal device
Inventor: GOMYO MASATO
IPC: F16J15/43
Filed: 1994-06-10
Abstract: PURPOSE:To attain thinning of a bearing and prevention of deterioration of seal performance so as to prevent scattering a magnetic fluid, by providing a notch partly in the internal periphery of a pole piece, placed in a negative pressure side at least at operation time, of the pole pieces. CONSTITUTION:At inoperative time, between internal peripheral surfaces of pole pieces 12A, 12B and a peripheral surface of a shaft 14 and in a notch 12a of the pole piece 12A, magnetic fluids 13A, 13B are magnetically held, to interrupt regions A, B sealed. When placed the region A in a low pressure side atmosphere and placed the region B in a high pressure side atmosphere, at operative time, since magnetic flux density in the notch 12a is smaller as compared with the other part, a magnetic seal in the notch 12a is unsealed. By the notch 12a, low pressure side space A communicates with space surrounded by the pole pieces 12A, 12B, and pressures are balanced between the low pressure side space A and the space surrounded by the pole pieces 12A, 12b, to prevent destructing a magnetic fluid ring 13A. In this way, thinning size of a bearing can be attained, and decreasing a seal pressureproof and deteriorating seal performance can be prevented.

Title: Automatic brightness adjusting device using light
Inventor: TSUNODA KATSUJI
IPC: G09G3/14
Filed: 1990-06-13
Abstract: PURPOSE:To adjust brightness automatically corresponding to the intensity of incident light by outputting a signal from a pulse generation part when an illuminance detecting circuit outputs an electric signal, and making a light emitting element illuminate with the brightness of DC pulses. CONSTITUTION:A photodiode 10 outputs an electric signal corresponding to the quantity of photodetection. An amplification part outputs an amplified output voltage and then a V/F converter 12 generates reference pulses of frequency corresponding to the voltage and outputs them to a main pulse generation part 13 and a slave pulse generation part 14. When the reference signal is inputted, the main pulse generation part 13 generates a main pulse signal and outputs it to the base of a 1st transistor(TR) 15. At the same time, the slave pulse generation part 14 generates and outputs a slave pulse signal to the base of a 2nd TR 16. Therefore, when a self-illumination type push button 3 is pressed, only a DC pulse based upon the pulse width and frequency of the main pulse signal is applied to the light emitting diode 3bb of the self- illumination type push button 3 and the brightness of the light emitting diode 3bb becomes maximum. A current flows to the 2nd TR 16 unless the self-illumination type push button 3 is pressed, and the brightness of the diode 3dd becomes about a half as large as that when the self-illumination type push button 3 is pressed.

IPC: H04N5/262
Filed: 1990-06-11
Abstract: PURPOSE:To obtain both a sense of proper resolution and proper S/N at all times by providing a means detecting a focus of a zoom lens, increasing the rate of addition of a contour signal to be added to a video signal at a wide angle mode with a short focus and decreasing the rate of addition in the telescope mode with a long focus. CONSTITUTION:A focus detection mechanism 4 detects how long the focus of a zoom lens is set and outputs a focus detection signal S to an addition rate variable circuit 13. The addition rate variable circuit 13 multiplies a predetermined addition rate Ai with a contour signal Ve corresponding to the inputted focus detection signal S and outputs the product to an adder circuit 11. The addition rate Ai is increased in the wide angle mode in which the focus of the zoom lens 1 is short to emphasize the contour of a video signal output Vo thereby enhancing a sense of resolution, and the rate Ai is decreased conversely in the telescope mode where the focus is long to improve the S/N. Thus, proper contour emphasis and well-balanced S/N are attained at all times.
