Title: Display device
Inventor: KODERA HIROYUKI
IPC: G09B29/10
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To provide a display device which can display information on a map, etc., even when an operator forgets a part of a telephone number or a zip code of a destination. SOLUTION: An operator inputs figures of 2nd plural digits from the most significant digit of a telephone number in an input circuit 11. When they are inputted, a control part 16 reads a map corresponding to the 2nd plural digits from a map memory 14 in response to an output of the input circuit 11. When the map has been read, a display device 12 displays the read map in response to the output of the control part 16. A map corresponding to each figure inputted in the input part 11 is stored in the map memory 14. Thus, a map can be displayed according to an inputted figure by inputting a figure from the most significant digit to an intermediate digit.

Title: Elongation-sensible converter
Inventor: YURUGEN NOIGEBAUAA
IPC: G01B7/16
Filed: 1986-12-10
Abstract: The transducer which is used for detecting high local surface extensions as occur, for example, during the measurement of the deformation behaviour of tyres during travelling mode, exhibits a hose 1 which is filled with mercury 5 and connecting wires 6 which close the hose and are electrically conductively connected to the ends of the mercury column. The hose 1, for which silicone is used as material, is embedded in a loop-shape in the preextended state in a highly elastic body 2, preferably of silicone rubber, the bent sections 3 of the hose 1 and its ends 4 protruding from the body 2. Due to the preextension of the hose 1, compressions can also be detected whilst the protruding of the bent sections 3 has the effect that the measured values are uninfluenced by transverse extensions. The connecting wires 6 have a greater dimension than the inside diameter of the hose 1 and are rounded at the ends located inside the hose. This transducer represents a compact component, can be repeatedly used, supplies continuously reproducible values and can be refilled in a simple manner when mercury is lost. <IMAGE>

Title: Speaking current supply circuit
Inventor: IMAI MITSURU
IPC: H04Q3/42
Filed: 1987-11-25
Abstract: PURPOSE:To absorb and eliminate noises by making a matching impedance element two partial impedance elements connected with each other in series and connecting a capacitor between their connection point and ground. CONSTITUTION:In a speaking current supply circuit 11, the matching impedance element is made the two partial impedance elements 29, 30 in series connection. The value of the impedance of each element 29, 30 is made Z/2. Between the connecting point between the elements 29, 30 and the ground, the capacitor 31 is connected. The impedance between the ground and a first and a second lines 13, 14 respectively is virtually Z/2, therefore, normal mode noises flow to the ground hence the potential comes lower. The capacitance value of the capacitor 31 is made sufficiently small at the frequency of the normal mode noises. By thus reducing the normal mode noises, common mode noises can be decreased.

Title: Timing locking system
Inventor: KAKO TAKASHI
IPC: H04L27/22
Filed: 1986-12-10
Abstract: PURPOSE:To attain a stable operation after a locking is attained by operating a PLL circuit at first as a primary PLL circuit and then operating a secondary PLL circuit after the locking so as to attain quick timing lock. CONSTITUTION:At first, the circuit applies locking as the primary PLL circuit. That is, only a 2nd integration circuit is activated and a 1st integration circuit is inoperative. In inactivating a 1st integration circuit, the output of a sampler 15 is inputted to the adder 12 of a 2nd integration circuit. Since only the 2nd integration circuit is in operation in this state, that is, since the PLL circuit is activated as the primary PLL circuit, the timing locking is applied quickly. When the timing locking is finished, a DC component detection circuit 20 extracts only the DC component of a signal, loads the detected DC component to a delay element 11 of the 1st integration circuit and activates also the 1st integration circuit in this state further.

IPC: H01L29/786
Filed: 1998-10-16
Abstract: PROBLEM TO BE SOLVED: To reduce the density of dangling bond by subjecting a thin-film transistor on a substrate to plasma processing in an atmosphere, where major components are hydrogen or hydrogen and nitrogen immediatly after the formation of a silicon thin film. SOLUTION: A silicon thin film 19 is formed on an insulting substrate 18. After a gate insulating film 20 and a gate electrode 21 are formed, a source region 22 and a drain region 23 are formed and an interlayer insulating film 24 is piled. Next plasma processing is performed in an atmosphere in which major components are hydrogen or hydrogen and nitrogen. In general the arrangement of silicon atom has many irregularities because the silicon thin film is in a polycrystalline state, the result many dangling bonds are contained. The density of the dangling bond can be reduced by embedding such dangling bonds with hydrogen atom. As a result, mobility is increased, a threshold voltage is reduced, and a thin-film transistor having a extremely large on-current can be formed.

IPC: G11B5/82
Filed: 1995-11-14
Abstract: PROBLEM TO BE SOLVED: To decrease the distance between a magnetic film and the interface interaction part in a protective film by forming a buffer film between the magnetic film and a lubricant film of a magnetic disk medium. SOLUTION: A base film 2, a magnetic film 3, a protective film 4 and a lubricant film 5 are successively formed on a nonmagnetic substrate 1. Further, a buffer film 4A is formed between the magnetic film 3 and the protective film 4. The base film 2, the magnetic film 3, the buffer film 4A and the protective film 4 are successively and continuously formed by sputtering, while the lubricant film 5 is formed by dipping. By the effect of the buffer film 4A, influences of the interaction from the buffer film 4A can be made small when the protective film 4 is formed on the buffer film 4A. Therefore, interactive strain can be avoided in a thinner film than in such a case that a protective film 4 is directly formed on a magnetic film 3. The protective layer spacing loss is equal to the sum of the film thickness of the buffer film 4A and the protective film 4.
