Patent JP-H05199085-A (JP)
Title: Waveform shaping circuit
Inventor: TERADA TAKAMORI
IPC: H03K5/08
Filed: 1992-01-20
Abstract: PURPOSE:To latch an input signal without changing a duty as an output signal by allowing a driver connecting to a connecting point of an input and an output buffer to generate a signal corresponding to an output signal of the input buffer and applying the signal to an internal circuit. CONSTITUTION:When a clock signal whose duty is 50% is inputted to an input buffer 2, an output buffer 3 outputs a clock signal delayed for propagation by 4 stages of inverters 21, 22, 31, 32 of the buffers 2, 3. Furthermore, since the layout is fixed and the leading time and the trailing time are uniform, the duty of the output clock signal of the buffer 3 is kept the same as that of the input clock signal, that is, 50%. On the other hand, an output clock signal of the buffer 2 is distributed to an output clock signal of the buffer 2 by the driver 4 connecting to the connection point of the input and output buffers 2, 3. Thus, the duty of the output clock signal is fixed independently of the configuration of the circuit 1.

Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To restrain abrasion between members in a power transmitting mechanism by transmitting the driving force of a motor to a rotationally moving member through a relaying member having flexibility. SOLUTION: In this motor-driven type brake, driving force of a motor is transmitted to a lever 230 through a deformable main brake cable 240, therefore at driving the motor, slide namely abrasion is not generated on the contact part between the main brake cable 240 and the lever 230. Further at driving the motor, slide is not generated on the contact part between the main brake cable 240 and the lever 230. The main brake cable 240 connecting the lever 230 to shoe spreading actuator 250 is flexible. Hereby, the degree of freedom for the arranging position of the shoe spreading actuator 250 is improved.

Title: Sense amplifier for virtually grounded flat cell
Inventor: TAE-SUN FAN
IPC: G11C16/02
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction of the sense amplifier and to perform cell operation quicker when a low cell is positioned in contiguity with a high cell to be read by maintaining a voltage between the cells at the same potential by means of a separate current/voltage converter and suppressing the occurrence of a leakage current accordingly. SOLUTION: The current of a bit line BL to be changed by a read data value is detected by a 1st current/voltage converter 11A to output a voltage corresponding to the current. This output voltage is compared with a reference voltage outputted by a 2nd current/voltage converter 11B by a voltage comparator 12 to output a data output DATA OUT corresponding to a data value of the flat cell which is read in accordance with a result of the comparison. The potential of the high cell of a high data storage to be read by using the output voltage of the voltage converter 11A and the potential of the low cell of a low data storage adjacent to the high cell are maintained at the same potential by a 3rd current/voltage converter 11C. Thus, the occurrence of a leakage current to the low cell side is suppressed.

Title: Adhesive film for semiconductor wafer dicing
Inventor: OTANI ISAO
IPC: H01L21/78
Filed: 1982-02-24
Abstract: PURPOSE:To ensure adequate adhesive force of a dicing film and to prevent contamination of semiconductor by a film by giving a structure to a bonding layer of said dicing film in the manner that a plasticizer is added to a copolymer using a polyvinylchloride as the structural unit. CONSTITUTION:A vinylchloride is used as a structural unit and moreover a monomer such as an acrylic glycidylester, acrylic acid, ethylene and vinyl acetate etc. is used as a structural unit of a second element. A methacrylic acid glycidyl is particularly suited among an acrylic acid, methacrylic acid having the glycidyl group or the ester of its derivative and content is about 1-10wt% as in the case of other monomer. If it is insufficient in amount, flexibility and adhesiveness also become insufficient, while if it is excessive, heat resistivity  becomes insufficient. Moreover, a plasticizer for ordinary polyvinylchloride such  as a dioctyl phthalate is added within the range of 10-40wt% for the copolymer in the 100wt%. A wafer 2 is placed on the film having a bonding layer 1  formed in the thickness of 50-400mu and is slightly pressed. This adhesive film has a sufficient adhesive force to the wafer and there is no fear of contaminating wafer with a plasticizer at the time of dicing.

Abstract: PURPOSE:To secure an optional adjustment for the application time of the photo gate voltage by providing the charge exhaustion part to exhaust the unnecessary charge and thus exhausting outside the charge generated at the photo sensor part during non-application period of the photo gate voltage. CONSTITUTION:The double phase transfer type CCD photo sensor consists of photo sensor part 1 containing photo sensor regions 11-1n, transfer gate 2, charge transfer part 3 and output part 4 respectively.

In such constitution, the non-application time of photo gate voltage phip is caused against part 1 right after end of charge take-in to part 3, and at the same time gate voltage phic is applied to draw out the charge generated at part 1 to part 8. And after end of this period, the application of voltage phic is discontinued immediately to start application of voltage phip. Thus, the charge diffusion can be prevented at part 1.

Abstract: PURPOSE:To obtain the size measuring instrument which easily and accurately measures sizes over a wide range by displaying respective images of an object of size measurement and a body whose size is already known on the same scale and displaying two cursors on the images. CONSTITUTION:A cursor coordinate input means 8 superposes cursor intersections HA and HB on both ends of the size-known part of a size-known image 4 by an image display means 6. A cursor deviation calculating means 10 receives horizontal and vertical coordinate values AX and AY, and BX and BY of the intersections HA and HB and outputs the root of the sum of the square of the difference between the coordinate values AX and BX and the square of the difference between the coordinate values AY and BY as a coordinate deviation W. The known size L of the size-known body displayed as the image is inputted from an actual size input means and inputted to a unit size calculating means 14 together with the deviation W to output a value L/W as a unit size l, which is stored 16. Then the means 8 superposes the intersections HA and HB on both ends of an image 2 and the means 10 outputs a deviation W similarly. Consequently, a measured size calculating means 18 multiplies the value W by the size l and outputs the result as a measured size D.
