Title: Semiconductor device
Inventor: EBINA MASAKI
IPC: H01L21/82
Filed: 1986-12-15
Abstract: PURPOSE:To test a semiconductor device extremely easily and in a short time by forming input/output test exclusive circuits to all the input/output cells corresponding to package terminals or predetermined input/output cells besides a product circuit originally produced in the master slice system semiconductor device. CONSTITUTION:A buffer is taken as an example as input/output cells. A signal input from an input buffer 1 at the time of an actual use state as a product passes through a desired product circuit 2. The signal is output at desired expected values from output buffers 4 through two-input one-output selectors 3. A select signal is transmitted over the two-input one-output selectors 3 from an input buffer 5 for changing over input/output cell tests so that the signal from the desired product circuit 2 is sent to the output buffers 4 at that time. When the input/output cells are tested, the two-input one-output selectors 3 select a bypass circuit 101 passing no desired product circuit 2 by the select signal from the input buffer 5 for changing over the input/output tests. Signals entering the input buffers 1 are transmitted directly over the output buffers 4.

Title: Method and apparatus for measuring flowing speed of ultrasonic wave
Inventor: SATO TOSHIO
IPC: G01F1/66
Filed: 1990-11-05
Abstract: PURPOSE:To measure the flowing speed of fluid at high temperature under high pressure highly accurately by measuring the average propagating speed of an ultrasonic waves at the wedge parts of ultrasonic-wave transceivers which are provided at the upstream and the downstream at small directing angles and a pipe wall, substituting the speed into a specified function, and determining the speed of the fluid in the pipe. CONSTITUTION:Similar ultrasonic-wave transceivers 1 and 2 having the small directing angles, the long wedge parts and the high temperature limits of ultrasonic-wave piezoelectric transducers 1A and 2A are arranged on the upstream side and the downstream side of a pipe 3 at a specified distance Lx. Transmitting and receiving circuit parts 11 and 12 are switched through a transmission/reception switching part 10. The propagating time of the ultrasonic wave which is reciprocating between the wedge parts of the transceiver 1 and the like is counted with a clocking means 13. Thus, the average propagating speed C at the wedge part and the ultrasonic-wave propagating speed C' of the ultrasonic wave which is propagating in the pipe wall are measured and stored in a first memory 14. When hot metal is used at this time, the linearly changing speeds C1 and C'1 are stored in the memory 14 together with the temperature. The function of the expression I is used based on the propagating times td and tn of the ultrasonic wave which is propagating through the fluid from the upstream side and the downstream side based on the stored values. Then, the fluid flowing speed at high temperature under high pressure is measured accurately.

Title: Preparation of reagent for liquid chromatography and liquid chromatography
Inventor: HAMANO YOSHIMASA
IPC: G01N21/77
Filed: 1985-12-27
Abstract: PURPOSE:To make microanalysis of PGs making use of the phenomenon in which a considerable difference in solubility exists between the ADAM itself and impurity when the temp. of an ADAM soln. is <=-10 deg.C. CONSTITUTION:The 9-anthryldiazomethane ADAM forms a deriv. by reacting with the carboxyl group of the PGs as shown in the formula and therefore the deriv. is subjected to a component sepn. by a liquid chromatograph and the fluorescent intensity thereof is measured. An example of PGE2 is shown here. The ADAM is dissolved in an org. solvent and after the soln. is cooled down to <=-10 deg.C, the insoluble component during cooling is removed in the absence of pressure. The refined 9-anthryldiazomethane soln. is then recovered. The soln. is subjected to the sepn. analysis by the liquid chromatography after the reaction to form the deriv., then the unreacted ADAM flows out of the sepn. column in precedence to the outflow of the PGs and therefore, the unreacted ADAM and the PGs can be fractionated. The impurities which are difficult to be separated from the PGs are removed prior to the formation of the deriv. and therefore, the trace detection of the PG deriv. is made possible.

Title: Semiconductor device and its manufacturing device
Inventor: ONO ATSUKI
IPC: H01L21/76
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To suppress generation of reverse narrow-channel effect caused by the reduction of impurities near a trench element separation by forming a silicon separation oxide silicon layer in the element separation structure of trench separation and a layer, where nitrogen is piled up at the silicon substrate side of an interface to a silicon substrate. SOLUTION: A pad oxide silicon film 2 is formed on a semiconductor substrate 1 and further a silicon nitride film 3 is deposited by the CVD method. Then, the silicon nitride film 3, the oxide silicon film, and the silicon substrate 1 at a region that becomes an element isolating region are etched to form a trench groove 5. Then, a photoresist 4 is released and the inner wall of the trench is oxidized by approximately 10 nm. When the inner wall is oxidized, piling up is made at the interface between the oxide film and the silicon substrate to become a silicon oxide film. The piled up silicon nitride film suppresses the diffusion of the silicon between lattices to the oxide film and suppresses the reduction in impurities near the interface between the oxide film and silicon of element separation, and hence suppresses the reverse narrow channel effect.

Title: Rodless cylinder
Inventor: ABE HISASHI
IPC: F15B15/28
Filed: 1994-11-10
Abstract: PURPOSE: To prevent the rotation of a moving piece, following the movement of it, even a magnet coupling is used for a rodless cylinder, by providing a guide surface for guiding the movement of the moving piece to a linking plate for linking a pair of end covers to prevent the rotation of the moving piece. CONSTITUTION: When compressed air is supplied/discharged to/from a port 42 provided on an end plate 3a, a piston 5 is airtightly moved in a cylinder tube 2 to move a moving piece 6 synchronizing with the piston 5 along the outer peripheral surface of the cylinder tube 2 by attracting force between magnet couplings 7a and 7b. At that time, since slide members 28,..., fitted to the four corners of the lower surface of the moving piece 6, are moved while slidingly contacting the guide surface 4a of a linking plate 4, the movement of the moving piece 6 can be smooth and the rotation of it can be surely prevented. Also, since the linking plate 4 is placed on the outer side of the moving piece 6, the moving piece 6 and resultingly the whole rodless cylinder can be miniaturized.
