Title: Gas cycle engine
Inventor: KAZUMOTO YOSHIO
IPC: F25B9/14
Filed: 1989-12-28
Abstract: PURPOSE:To equalize driving force moving the pistons of both first coil and second coils, and to reduce the vibrations of a gas cycle engine by connecting the first coil and the second coil in series and making the same currents flow through the first coil and the second coil. CONSTITUTION:When an AC power is connected to a first electric contact 24a and a second electric contact 24b, Lorentz force in the axial direction works to a first coil 20a and a second coil 20b by the interaction of the permanent magnetic fields of annular spaces 26a add 26b, and pistons 3a and 3b begin to be vibrated in the axial direction. Since the vibrations are equalized mutually and conducted in the opposite directions, an operating gas sealed into an operating space is compressed and expanded, and cold is generated in an expansion space 8. Since the coil 20a and the coil 20b are connected in series at that time, currents made to flow through the coil 20a and the coil 20b are equalized completely even when the resistance and inductance of both coils differ. Accordingly, force driving the first piston 3a and the second piston 3b is made the same, thus also reducing the unbalance of the phase and amplitude of the reciprocating motion of both pistons, then remarkably lowering the vibrations of a gas cycle engine.

IPC: G06F9/06
Filed: 1993-12-15
Abstract: PURPOSE:To automatically generate an object code suitable for system performance without correcting a source program at all by detecting any machine instruction, for which executing time exceeds maximum allowable time, out of machine instructions in the source program. CONSTITUTION:Maximum allowable time 114 holds the maximum time to be allowed as the executing time of one machine instruction designated by the starting time option of a language processing program 11. An executing time deciding part 113 of a language processing program 91 reads the executing time of the machine instruction temporarily decided by a machine instruction deciding part 111 from a machine instruction table 915 and compares it with the maximum allowable time 114. When the maximum allowable time 114 is longer or equal with the executing time of the machine instruction, the code of the machine instruction temporarily decided by the machine instruction deciding part 111 is generated by a code generating part 919. When the executing time of the machine instruction is larger than the maixmum allowable time 114, an error 94 is outputted and it is reported that the machine instruction with the executing time exceeding the maximum allowable time 114 is detected.

Title: Aligner
Inventor: KOMATSU KOICHIRO
IPC: H01L21/027
Filed: 1991-12-25
Abstract: PURPOSE:To prevent the degradation in alignment accuracy by positioning a third diffraction grating on a plane almost conjugate to that of either of a mask and a substrate to be exposed or a plane in proximity thereto and securing a fourth diffraction grating for producing reference signals on a holding member, integrating it with the third. CONSTITUTION:A transmitted/received light separating prism 6 is placed in the optical path between a first objective glass 7 and a second 4. Thus, a part of each of two transmitted light beams is guided into a reference signal producing part; primary diffraction light DR1 and DR2 from reticle marks RMa and RMb is guided to a reticle detection system; and a interference beam BTW from a wafer mark WM is guided to a wafer detection system. This permits positioning the reference signal producing part, the reticle detection system and the wafer detection system in proximity. It also enables integrating these three items and securing them on a metal plate of low coefficient of thermal expansion. Thus, a monitor grating plate 13 and a reference grating plate 9 move in almost the same manner regardless of the fluctuation of temperature.

Title: Radar image displaying device
Inventor: SAITO KOICHI
IPC: G01S7/295
Filed: 1991-12-26
Abstract: PURPOSE:To rotate an antenna at a high speed without deteriorating bearing resolution. CONSTITUTION:Coordinate transformation by means of a coordinate transformation circuit is performed so that the transformation can be started from coordinates (XE, YE) on the periphery of a radar video and terminated at its own position (XS, YS) of a ship at the central part of the video. When the transformation approaches the position (XS, YS), writing in a radar image frame memory is inhibited by means of a circuit for inhibiting multiple writing of radar images. In response to the inhibition, the coordinate transformation circuit stops the coordinate transformation regarding the sweep and starts coordinate transformation regarding the next sweep. Therefore, an antenna can be rotated at a high speed without deteriorating bearing resolution, since one-sweep transforming time is reduced by the time after the writing is inhibited by means of the circuit for inhibiting multiple writing of radar images.
