Title: Manufacture of compound semiconductor device
Inventor: TARA KATSUJI
IPC: H01L21/324
Filed: 1991-09-10
Abstract: PURPOSE:To obtain a stable activation ratio which is reproducible because a wafer can be heated uniformly irrespective of its surface state. CONSTITUTION:A coil 2 and a capacitor 4 are connected to a power supply 3 in order to generate electromagnetic waves at a high frequency of 15MHz; a quartz tube 1 is arranged inside the coil 2; a wafer stage 6 whose main material is carbon is arranged inside the quartz tube 1; a wafer 5 after an ion implantation operation is arranged on it. The electromagnetic waves at a frequency decided by the coil 2 and the capacitor 4 are generated in the coil 2, and the inside of the quartz tube 1 is heated by the electromagnetic waves. The wafer stage 6 whose main material is carbon is first heated, and the wafer 5 is then heated. Thereby, the wafer 5 is heated uniformly. Since the frequency of the electromagnetic waves is low at 15MHz, a skin depth is long and the wafer 5 can be heated uniformly without depending on its surface state.

Abstract: PURPOSE:To prevent the hunting phenomenon of a rotary tiller by fixing the position of the rotary tiller at a position only for some period after the start of a tilling work and setting the holding time of the rotary tiller in accordance with the heave of tilled soil at the time of the start of the tilling work. CONSTITUTION:A hydraulic cylinder 5 is expandably controlled by a control means to maintain the detected value of an angle sensor 9 to a pre-set value, the angle sensor 9 being used for detecting the angle of a cover 8 to a rotary tiller 4. The maximum value of the detection value of the angle sensor is memorized only for the first set period from the start of the tilling work, and when the detected value of the angle sensor reaches the pre-set value in the descending operation of the rotary tiller, the descending operation is stopped and held only for the second set period. The larger the memorized maximum value is, the longer the second set period is set. After the passage of the second set period, the lifting control of the rotary tiller is operated and a tilling depth A is maintained at a set value.

Title: Dictionary preparation method
Inventor: IDEMOTO HIROSHI
IPC: G06K9/68
Filed: 1990-08-31
Abstract: PURPOSE:To restrain dictionary preparation time by selecting the maximum characteristics of a distributed value while utilizing the characteristic vector of a learning sample in a system equipping plural dictionaries with one category (character) and executing the classification of the sample about its average value on the above-mentioned characteristics until it turns to a predetermined number of clusters. CONSTITUTION:A distributed value calculation processing part 11 of a clustering execution part determines the distributed value of respective characteristics against the set of a learning sample. Next, a maximum distributed value characteristics selection processing part 12 determines a characteristic (f) where the distributed value becomes the maximum. In a cluster division processing part 13, only the characteristic (f) is focused, and the learning sample is divided into a smaller or bigger value than an average value (m) of the characteristic (f). An end decision processing part 14 checks whether or not the divided clusters reach the number designated by the divided clusters. When it is not reached, the cluster division is performed further. Then, a cluster centroid calculation part 15 calculates the center of gravity for each cluster to obtain a sub-category dictionary.

Therefore, when the internal combustion engine 1 is stopped, convection of cooling water of a part except for the heat accumulating tank 4, for example, piping or the like connected to the heat accumulating tank 4 and cooling water of the heat accumulating tank 4 can be prevented. Therefore, since mixing of cooling water of a part except for the heat accumulating tank 4 and that of the heat accumulating tank 4 can be prevented, heat reserving capacity of the heat accumulating tank 4 can be improved.

IPC: H04N1/40
Filed: 1987-09-17
Abstract: PURPOSE:To attain a simple picture processing with simple circuit constitution by handling the inverting output of a preceding picture element as picture- processed data. CONSTITUTION:An A/D converting circuit 1 converts the picture data, which are inputted from an external part, to a different threshold and sends it. Thus, for the output ot an OR gate 5 '1' is outputted when the respective thresholds are '1' and '0' is outputted when they are '0' respectively as the picture- processed data. When the data of the respective thresholds are gray areas, the inverse of Q output of a data delay circuit 6 is outputted through an AND gate 3 and the OR gate 5 as the picture-processed data. At such a time, the inverse of Q output is the inverting data of the preceding picture-processed data and for the data of the gray area, white and black are alternately outputted. Then, a half tone is artificially expressed.

Title: Latch circuit having voltage level conversion function and flip-flop circuit
Inventor: HAMADA MOTOTSUGU
IPC: H03K19/0185
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of required elements, to reduce power consumption and to accelerate an operation speed by providing a latch circuit with a voltage level conversion function. SOLUTION: When a clock signal CK is high, both transmission gates TG1 and TG2 become conductive. A slave latch circuit SL becomes a circuit which increases a voltage level of an intermediate output signal from a data output terminal Q1 in a master latch circuit ML and makes it pass through as it is when the signal CK is high. That is, since the voltage of the signal is VDD2 when the intermediate output signal from the terminal Q1 is high, the voltage VDD2 is converted into VDD1 that is higher voltage than it and an output data signal OD is outputted as a high signal. On the other hand, since the voltage of the signal is ground when the intermediate output signal of the terminal Q1 is low, the ground potential is just outputted as the signal OD.

Title: Tunnel pit mouth
Inventor: KOGURE YUICHI
IPC: E21D9/14
Filed: 1997-08-27
Abstract: PROBLEM TO BE SOLVED: To conduct vehicles coming in and out of the tunnel by forming surface walls at the pit mouth in a manner being continued in the inner wall surface of the tunnel and gradually expanded toward the outside and lower side. SOLUTION: Surface walls 2 being gradually expanded toward the outside are formed continuously on the inner wall surface 1 of a tunnel at the pit mouth. The wall surfaces are slanted forward and faced downward so as to lower the luminance of the wall surfaces 2. The wall surfaces 2 are formed by being made narrow at its top part, and wide in turn at its bottom part. The bottom part of the wall surfaces 2 is made longer, and the slant of the slope is made gentle for forming a long retaining wall, and then the width of a road 3 at the pit mouth is made broad by the turn toward the outside. The width of the surface walls 2 can be equal, or substantially equal at the top part and bottom part, or the surface walls 2 can be different in width in the top part and bottom part, or the left and right side. In this way, vehicles can be conducted safely, and also can ensure the safety mentally.  In addition, finish is good on the execution, and further, change in the length of the surface walls permits disposal to be done in accordance with conditions of the natural ground and slope near the pit mouth.

Title: Image variable power device
Inventor: HAYASHI SHIGEO
IPC: H04N1/393
Filed: 1989-09-08
Abstract: PURPOSE:To suppress the deterioration of picture quality after applying a variable power by moving a processing bit to a bit not being decided as an isolation bit when the processing bit selected at a constant interval corresponding to a variable power ratio is equivalent to the isolation bit. CONSTITUTION:A bit string is inputted as picture element data PD. In a period when picture elements G8, G9, G13, G19, G20, G21, G22, G23, and G24 that are isolation points are outputted, a signal S1 outputted from a NOR circuit 8 is changed to a logic L level. At the picture element G13 which becomes the isolation point, the output signal S6 of a NAND circuit 14 goes to a logic H level when a signal S3 goes to the logic H level. When the signal S1 rises to the logic H level in the period of the next picture element G14, a signal S5 goes to the logic H level, therefore, the output signal S6 falls to the logic L level. Simultaneously, since the output signal S7 of a NOR circuit 12 rises to the logic H level, an FF 11 is reset with a timing when a clock phi0 is outputted next.
