Title: Scanning type electron microscope
Inventor: GOTOU YOSHIAKI
IPC: H01J37/22
Filed: 1982-05-08
Abstract: PURPOSE:To secure a uniform image on the same condition, by cutting a secondary electron signal into two separate portions, low frequency and high frequency, while installing a signal correction device regulating the high frequency portion according to the magnitude of the low frequency portion and thereby forming the image with the corrected signal. CONSTITUTION:A signal correction device 4 for turning a detection secondary electron signal S2 into a correction secondary electron signal S3 for correction is installed in addition. This correction device 4 is fitted with a low-pass filter 42 which passes only a delay circuit 41 having the signal S2 delayed for the specified time long and a low frequency constitutent and calculates a difference between a delay signal S41 and a low frequency signal S42 with a differential amplification circuit 43. On the other hand, also it calculates a difference between a reference level signal S45 of the specified voltage value and the low frequency signal S42 with a differential amplifier 46, then amplifies a high frequency signal S43 with an amplifier 44 in accordance with a gain correction signal S46 out of this differential amplifier 46 and transmits the correction secondary electron signal S3 to a display unit 3. With this, a uniform image can be secured by using the secondary electron signal uninfluenced by any external cause.

Filed: 1990-03-28
Abstract: PURPOSE:To improve quality of a thermistor by holding a ceramic base body after a firing process or during the same process for a fixed time in a high temperature and to quickly cooling thereafter to normal temperature. CONSTITUTION:After temporarily firing a raw material, in which at least tow kinds of transition metal oxides are mixed at a fixed distribution ratio, the mixture is crushed for molding and firing.

Title: Molding of blow molded body made of synthetic resin
Inventor: SEKI YUUKI
IPC: B29C33/38
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To control the draw down of sheets at heating by a method wherein an air permeable heat-resistant supporting member is spanned between both the sheets parallel to each other so as to carry out the subsequent forming operation under the condition that the above-mentioned spanned state is retained. SOLUTION: When thermoplastic synthetic resin sheets 1 and 2 are pinched by clampers 4a and 4b and supported parallel and horizontally, one layer of air permeable heat-resistant supporting member 6 parallel to both the sheets 1 and 2 is simultaneously spanned. The spanned position of the air permeable heat-resistant supporting member 6 is normally between an upside sheet 1 and a spacer 3. Next, both the sheets 1 and 2 are softened by heating from above and below with heaters 7a and 7b. At this time, though both the sheets 1 and 2 tend to sag with the rise of temperature, the drawdown of the upside sheet 1 is suppressed, since the upside sheet 1 is supported by the air permeable heat-resistant supporting member 6. Further, the sagging of the downside sheet 2 is suppressed together with that of the upside sheet 1 by balancing the pressure in a closed space 5 with the atmospheric pressure.

Abstract: PURPOSE:To obtain always correct servocontrol or sector information by providing track width and either or the servocontrol information or sector information or the combination thereof in the form of holes or arrays of nonmagnetic parts to a substrate or magnetic film of a magnetic recording medium. CONSTITUTION:The hole arrays 11, 12... conformed to the servocontrol information are formed at every track width w in conforming to the w to part of the magnetic film on the substrate 1. The medium moves in an arrow direction and the hole arrays have the width equal to an intertrack gap g. The row holes 11, 12... are otherwise provided preliminarily to the substrate 1' and the magnetic film 2 is superposed thereon, then the holes are formed to the film 2 as well, or part of the magnetic film 2 on the substrate 1 is made nonmagnetic and the arrays 11', 12... are formed. Such patterns are indeliable and remain even if a magnetic head tends to erase the same accidentally during use and therefore, the always correct servocontrol information or sector information is obtd. The recording medium is thus formed by using a photomask as well as an etching soln., laser etching or a method for immersing the substrate in an aq. Cr2O3 soln. to make the magnetic film nonmagnetic.

IPC: H01L21/3065
Filed: 1988-03-29
Abstract: PURPOSE:To suppress amount side-etched and to enable a separation groove with a narrow groove width by forming a shallow groove performing anisotropy etching of silicon substrate using a first gas whose main constituent is chlorine chemical compound and then performing anisotropy etching of a shallow groove using a second gas whose main constituent is fluorine chemical compound. CONSTITUTION:An opening part 3 of 1mum in thickness is etched and is formed on an insulation film 2 formed on the main surface of a silicon substrate 1 until the silicon substrate 1 is exposed. Then, by performing anisotropy etching of the exposed silicon substrate 1 using a first gas whose main constituent is the chlorine chemical compound, a shallow groove 4 which is 1/10-1/3 of desired depth is formed. This etching allows polymer to be adhered to the side wall of the groove. Then, by performing anisotropy etching using a second gas whose main constituent is chlorine chemical compound with a large etching rate, a deep groove of 2-6mum in depth is formed. In this case, polymer adhered from the previous process restricts side etch. It allows amount of side etch to be restricted and a separation groove with a narrow groove width to be formed.

Abstract: PURPOSE:To speed up and stabilize the operation by connecting a P-channel transistor for active load in series with respective complementary bit lines and a P-channel transistor used as diode for clamp in parallel with the said transistor. CONSTITUTION:When a clock pulse is H, the P-channel transistor for equalizer 55 turns off, and a suction current corresponding to the storing state of a memory cell 10A etc. flows through one 22 of the pair of bit lines 22 and 23 precharged by a power source potential VDD that are released from precedent short circuited state via the P-channel transistor 53 with high resistance and small area connected in series with the line 22. As a result, the potential of the line 22 swiftly lowers, while that of the line 23 to which a transistor 54 similar to the one 53 is connected in series rises swiftly, and accordingly, the access time becomes shorter, and a high-speed operation is attained. Meanwhile, to the transistors 53 and 54, a P-channel transistor used as diode for clamps 51 and 52 of low resistance and large area respectively is connected in parallel. A large current flows through the said transistors, therefore, a potential correspondent to the storing content of the cell 10A etc. of nodes R and S is rigorously clamped to provide a stable operation.
