Title: Matching pattern for semiconductor device
Inventor: YAMADA KOUJI
IPC: H01L21/302
Filed: 1978-04-27
Abstract: PURPOSE: To avoid the effect which is caused by entering of the scribing line thicker than the matching pattern into the matching pattern region and then to detect optically the scribing line entering the pattern region in the automatic detection to use it as the electric signals after differentiation.  
     CONSTITUTION: The matching pattern 5 is formed with parallel lines having a fixed space between, and the size of matching pattern region is about 1mm × 2mm. Scribing line 7 is inserted into region 6 formed on the mask, and the object formed on the wafer is piled on pattern 4. When an optical scanning is given to region 8 in a fixed direction with photoelectric conversion, pulse signals 4', 5' and 7' are made to oppose to pattern 4 and 5 plus line 7 respectively. Signal 7' features the time duration in comparison with pulse 4' and 5'. Thus if signal 7' is differentiated and shaped under the proper conditions, signal waveform 10 is obtained. As a result, matching pattern 5 and 4 can be detected obviously. In this method, no consideration is required for the position of the matching pattern, and the scribing lines can be formed continuously. Thus, the scribing process is simplified.

Title: Subscriber's circuit
Inventor: TAKADA KENZO
IPC: H04Q3/42
Filed: 1985-03-14
Abstract: PURPOSE:To prevent occurrence of a hit of speech voice by connecting in cascade a two-wire equivalent terminal circuit, a low-pass filter and a phase invertor in parallel with a two-wire equivalent terminal circuit and applying output signals of the two circuits to the input terminal of a sound signal amplifier circuit. CONSTITUTION:Feeding circuits 3-1, 3-2 changes sending of current at every time corresponding to speaking distances by a command of a central processing unit 4. Accordingly, a voltage V between lines of a circuit 2 changes as shown in the figure A. Potentials V1, V2 in codec-side terminals of feeding circuits 3-1, 3-2 are made reverse in terms of phase to each other with time as shown in the figure B. Accordingly, when a variation I1 of DC component in the output side of a two-wire equivalent terminal circuit 5-1 and a variation I2 of DC component in the output side of a low-pass filter 12 are observed, a antiphase AC signal component is generated at a polarity inversion point for charging as shown in the figure C. Thus, variation is canceled in the input side of an aural signal amplifier circuit 6 as shown in the figure D. Accordingly, signals that become over-load on the amplifier circuit, an amplitude comparator in the codec etc. are not given, and the hit of sound signals does not occur.

Filed: 1983-03-26
Abstract: PURPOSE:To travel a magnetic tape properly by inclining the longitudinal edge of a magnetic head from the advancing direction of the magnetic head so that the component of frictional force applied to the travelling magnetic tape is applied to a guide groove direction. CONSTITUTION:The magnetic head 7 is fixed in a slot 6b of an upper drum 6 through a tape seat 17. When the magnetic head 7 is arranged with inclination, the longitudinal edge of the magnetic head 7 is inclined and frictional force (q) having alpha angle from the advancing direction A of the slot 6b is generated between the magnetic head 7 and the magnetic tape 15. If it is defined that the angle beta of resultant force R of frictional force (m), (n), (q) generated against forwarding direction of the slot 6b part is beta, the frictional force R is as shown in the figure B on the magnetic tape 15. The components of the frictional resultant force R in the longitudinal direction of the magnetic tape 15 and the vertical direction are R1 and R2 respectively. The component R2 of the frictional force acts as the force guiding the magnetic tape 15 to the guide groove direction, so that the lower end of the magnetic tape 15 is prevented from being separated from the guide groove.

Filed: 1996-03-08
Abstract: PROBLEM TO BE SOLVED: To correctly and easily register a code plate and a rotary shaft when the code plate is mounted, and prevent the code plate from being mounted upside-down. SOLUTION: A hole 3a for a positioning pin positioning a code plate 3 to a rotary shaft of an encoder is formed in the code plate 3. The code plate 3 is positioned to the rotary shaft by the use of the positioning pins. An asymmetric arrangement pattern is preferred for the positioning pins on the code plate so that it can be distinguished whether the code plate is a front face or a rear face. The code plate 3 is thus prevented from being mounted in an inverted direction.

IPC: G01N1/22
Filed: 1981-04-08
Abstract: PURPOSE:To obtain a small-sized sonde device which has excellent sealing characteristics by detachably connecting a measurement lance, which is inserted into and extracted from a furnace, to a driving lance, and then arranging a driver body in parallel to the lances. CONSTITUTION:While a driving lance 9 is clamped by a holder 21 and a chuck 19 by turns, a driving cylinder 18 is operated and while the tip of a measurement lance 8 reaches an opening part 3, the driving lance 9 is clamped by a chuck 19 at a final end position. Then, the driving cylinder 18 is operated to insert the measurement lance 8 into a furnace 2 by prescribed length, and measurement is started. Since a sealing mechanism 7 is on the driving lance 9 which is not inserted into the furnace all the time, invariably excellent sealing characteristics are secured. The driving cylinder 18 is arranged in parallel to the lances, it does not take up much room. The measurement lance 8 and driving lance 9 are attachable to and detachable from each other, so the measurement lance 9 which is disabled to be used owing to deformation is disconnected while placed in the furnace.

Abstract: PURPOSE:To provide a hammer stop adjustment device for a piano sound stopping device by which a necessary stop position is easily adjusted even though the position is delicately deviated for every hammer. CONSTITUTION:If a male screw 37 is scarcely projected from the buttom surface of an edge section 30c, a tip section 33b of an elastic plate 33 is positioned at 33b (1). If the screw 37 is slightly screwed, it is positioned at 33b (2) and if the screw 37 is further screwed, it is positioned at 33b (3). Thus, the whole plate 33 is oscillated and the position of a foamed urethane 40 is lowered. The abutting position of a hammer shank 21 is easily adjusted even though the abutting position is not appropriate due to the error in the shape of the hammer or the deformation after producing.
