Filed: 1982-12-22
Abstract: PURPOSE:To offer a glass delay line having a large spurious attenuation by increasing virtually the length of an input and an output transducer provided respectively to an input and an output faces of a glass delay element. CONSTITUTION:The glass delay line of this invention is provided with a glass delay element 1 and an input transducer 2 and an output transducer 3 fitted respectively to input and output faces 1a, 1b at slope ends of both sides of the element. Both faces of the glass delay element 1 are provided with a spurious absorbing body 8 to regulate the spread of a signal beam along the path of an ultrasonic wave signal. A notch 4 prolonged in the broadwise direction is provided respectively along each end face of the input and the output transducers 2, 3 to the input and output faces 1a, 1b of the glass delay element 1. Thus, the effective length of the input and output transducers 2, 3 is increased by the width of the notch 4 according to the principle of mirror image. As a result, the path of the spurious (b) is as shown in broken lines of Figure.

Abstract: PURPOSE:To moderate deceleration at the time of coasting travel as well as to prevent a car speed from overspeeding at a downhill, by stopping a fuel supply at time of the coasting travel and opening a throttle valve, while closing this valve when detecting a rise in the car speed. CONSTITUTION:Various sensor signals are inputted into a control unit 8, controlling an injector 7 and a throttle valve 2. When this control unit detects a fact that low fuel consumption running conditions and coasting travel conditions are satisfied from each signal out of a car speed detector 11, a cooling water temperature sensor 12, a low fuel ratio running switch 19, etc., it stops fuel injection out of the injector 7, while it opens the throttle valve 2. In addition, a fact that a car speed goes up is detected, controlling this throttle valve 2 in the closing direction. With this constitution, even when the car speed goes up at a downhill, the car speed is properly controllable.

Title: Pattern processing method
Inventor: KAKIGI GIICHI
IPC: G06T1/00
Filed: 1983-11-30
Abstract: PURPOSE:To remove unevenness in the vicinity of the boundary of patterns only without removing minute defects by removing only empty areas in the vicinity of the boundary of the patterns in the preprocessing of patterns at the time of inspection by detecting the patterns optically. CONSTITUTION:Each part represented by A, B, C, and D at the left side of the figure shows sensors respectively and sensors B and D shown by squares with black dots correspond to black (1) and each of the sensors C corresponds to white (0). The A, B, C, and D at the right side show outputs of preprocessing of patterns and are connected with the sensors by means of an inverter 11, AND gate 12, and OR gate 13. When black appears at the marginal part of a pattern and unevenness occurs at this part, the A at the outside of the B is white and the B is connected with the D by black, and therefore, unevenness in the vicinity of the boundary of patterns disappears by preprocessing. When the disconnected part of the line is preprocessed, the A is not white and the B is connected by black with the D. Therefore, the disconnected part is left as white, namely as a disconnected part.

IPC: G11B20/18
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To accurately reproduce data even when the deformation of a track is caused by expansion and contraction of a magnetic tape and the like occurs. SOLUTION: Data is product-coded, is added with a track ID and a block ID for every SYNC block, and is recorded in a tape 206 with an oblique track. In reproduction, when trace is not performed correctly owing to deformation of a track and the like and C2 correction is not performed completely, it is discriminated by a discriminating circuit 218 so as to perform retrying processing. The tape 206 is returned to the original position, while speed is reduced to half when recorded, and traced without a gap. Reproduced data is C1-corrected by a C1 decoder, supplied to an extracting circuit 213 through a terminal 212b, and the block ID and the track ID are extracted. Data traced by plural times is stored in a memory 215, and rearranged in the correct order, based on extracted ID.  This data is C2-corrected by a C2 decoder, when an error does not exist, the data is outputted, when an error exists, retrying processing is performed again.

Abstract: PURPOSE:To prevent the consumption of a servo pressure a large amount by providing a safety valve controlled responding to the comparison of the pressure in two pressure generating chambers of a master cylinder between a switching valve which links the antiskid control valve side to the pressure chamber of a fluid pressure and a fluid pressure device, when the antiskid control is operated. CONSTITUTION:When there is a failure in either piping system connected to the first fluid pressure generating chamber 19, the fluid pressure is not generated in the first fluid pressure generating chamber 19 even though a brake pedal 12 is depressed, but a fluid pressure is generated in the fluid pressure generating chamber 20 of a normal system. As a result, in a fail valve device 2, a fail piston 35 moves to the right side depending on the pressure difference in one side master cylinder pressure chambers 39a and 39b partitioned on both sides, the operation rod 48b of one side switch 47b rides on the larger diameter part 49b of the fail piston 35, and the switch 47b is operated. Consequently, while the excitation of the switching valve 3b of one side electromagnetic valve 4b is prevented, an alarm is generated to guarantee the safety.

Title: Method of detection of positioning mark
Inventor: TANIMOTO TETSUZOU
IPC: G05D3/00
Filed: 1982-12-27
Abstract: PURPOSE:To improve the through-put in detection of positioning marks by a method wherein, when an overlapped or approached condition is generated on one of the image signal waveform patterns of each positioning mark, the pattern having wider width is detected, the relative position of a wafer and a mask is recognized without performing a step-feeding process, thereby enabling to cut down the time required for alignment. CONSTITUTION:When an overlapped or approached condition is generated on one of image signal waveform patterns of each positioning mark, it is considered that the overalpped or approached condition is generated on the wafer concerned and the positiong mark of the mask by detecting the pattern having wider width, and the relative positional relation is matched by calcurating the amount of positional deviation between the two. For example, pattern widths D1=Iu1-d1I and D2=Iu2-d2I are calculated by an arithmetic operation circuit 15 using the edge informations d1 and d2 of the positioning mark image signal waveform pattern on the mark and the edge information u1 and u<2> making a pair with the above- mentioned informations, and it is recognized that the positioning mark is approached to the wafer 2 having wider width between pattern widths D1 and D2, or that the positioning mark is overlapped.
