An upper electrode 22 is formed on a capacitor insulating film 11 to cover the upper part of the lower electrode 21. The lower part of the lower electrode 21 has the same shape as a contact hole 17 and extends upward over the contact hole 17 under the state of the same shape. Thus, a capacitor part 23 is formed of the lower electrode 21, the capacitor insulating film 11 and the upper electrode 22. By this semiconductor device, the surface area of the lower electrode 21, that is to say, the quantity of the stored electric charge, can be determined by the magnitude of the contact hole 17 and the deposited thickness of a silicon oxide film.

Title: Information reader for information recording medium having track structure
Inventor: MURAMATSU EIJI
IPC: G11B20/10
Filed: 1989-07-10
Abstract: PURPOSE:To prevent the interruption of reproduction due to sound jump or the like by reading information corresponding to the recording information of a read object track from a storage means of read information with a 2nd scanning means at the time of the occurrence of a track jump of a 1st scanning means and incorporating the information into normal read information. CONSTITUTION:A pulse generator 4 generates a pulse P attended with the revolution of a spindle motor 2 and is fed to 1st and 2nd delay circuits 7. The 1st delay circuit 5 retards preceding read information B by a light spot SPB by prescribed time and outputs the result to a selection circuit 6, while an object read information A by a light spot SPA is directly inputted to the selection circuit 6, which selects either the object read information A or the preceding read information B in response to a detection signal Pj from a track jump sensor 8 and outputs the result to the 2nd delay circuit 7. The selected information is retarded by the prescribed time by the 2nd delay circuit 7 and the result is outputted as time series sequence information string and the detection signal Pj is given also to a track jump instruction device 9. Thus, the interruption of reproduction due to track jump is prevented.

Title: Thermal transfer recording method
Inventor: SATO HIROSHI
IPC: B41J31/00
Filed: 1986-07-30
Abstract: PURPOSE:To give printing having high density and good sharpness and erasable before fixing but indelible after fixing, by a method wherein a first ink layer capable of holding a shape at the time of heating and a second ink layer developing adhesiveness at the time of heating are provided on a support and heat or/and pressure is applied to a visible image to destruct the microcapsules contained in the second ink layer and fixing is performed by softening the second ink layer. CONSTITUTION:The first ink layer 14 near to a sheetlike support 12 holes the shape of a dot part at the time of the application of heat and becomes easy to release from the support through a heat-meltable binder. A second ink layer 15 holds adhesive strength to paper to be recorded at the time of the application of heat and is made easy to release from the support to be transferred. After a printed character is formed, the microcapsules containing an oil agent in the second ink layer 15 are destructed by heating or/and pressurizing and the ink layer is softened by the oil agent to fix the printed character. Since the first ink layer 14 corresponding to a dot part to which heat is applied does not flow and holds a dot shape, an image having high printing density is obtained even on paper inferior in smoothness.

To the element cell thus constituted, a cap- shaped auxiliary terminal 16 is spot-welded to a pole terminal required according to the requirments in order to obtain a purposed terminal-shaped cell. The parts can be completely interchangeably used thus obtaining desirable efficiency in both aspects of parts producement control and equipment investment.

Title: Detecting method of defect of pattern
Inventor: OKUYAMA YASUSHI
IPC: H01L21/027
Filed: 1980-12-16
Abstract: PURPOSE:To simply and effectively detect the presence or absence of a dust particularly when a pattern is transferred upon patterning with a reduction projecting exposure device (DSW) by coating an infrared absorbing photoresist on a semiconductor wafer. CONSTITUTION:To discriminate whether or not a pattern formed by a DSW is normal, a wafer 21 is set at one side of a comparison detector, and a reference pattern 25 of the same size as a chip is set at the other. Infrared rays 22 are emitted from below the wafer 21. The infrared ray is converted to visible ray by a converter 27 and is then colored via a filter 28 into an eye lens 29. On the other hand, a visible light 23 having a color complement to the light is projected to this reference pattern into the lens 29. Since two lights being complementary to each other are introduced into the lens 29 in this manner, improper pattern can be readily detected by the difference of their colors.

Abstract: PURPOSE:To prevent completely malfunction due to a propagating delay time between LSI systems by forming a timing by a half clock before than the actual timing at a transmission side LSI and transmitting the timing to a receiving side LSI, in the LSI comprising >=2 elements. CONSTITUTION:A flip-flop 23 of the transmission side LSI21 cuts off an original timing signal (d) at the trailing edge of an inverted clock pulse (a) to form a signal (e). To obtain a timing signal (f) used in an LSI21, the signal (e) is interleaved at the trailing edge of a clock pulse (b) by using a flip-flop 24. Further, the signal (e) is given to the receiving side LSI22 through pins 28, 29 and becomes a signal (g) with a slight delay due to the propagation delay time. The clock pulse (b) is given to the LSI22 through pins 30, 31 with a slight delay similarly and becomes a clock pulse (c). A signal (h) is obtained at the LSI22 to obtain the timing used for the internal circuit by interleaving the signal (g) at the trailing of the clock pulse (c) at a flip-flop 25.
