Title: Method and device for detecting position and alignment device
Inventor: SHIBATA HIROMASA
IPC: G01B11/00
Filed: 1990-04-19
Abstract: PURPOSE:To spread the range of detection as detection resolving power required in a position transducer utilizing optical heterodyne interference light is left as it is kept by separating each diffracted light from first and second bodies resulting from the + or - primary irradiation direction and each diffracted light from the first and second bodies resulting from the + or - quaternary irradiation direction respectively and detecting phase difference among beat signals by each diffracted light. CONSTITUTION:Since the planes of polarization are displaced at 900 by half wave plates 50, 51 on their midways in - primary diffracted light and - quaternary diffracted light reflected by mirrors 31, 33, both diffracted light mutually interfere with + primary diffracted light and + quaternary diffracted light respectively by polarizing beam splitters 52, 53, thus acquiring optical heterodyne interference light. The phase difference of beat signals resulting from + or - primary diffracted light and the phase difference of beat signals resulting from + or - quaternary diffracted light are detected in a signal processing control circuit 7, thus measuring the quantities of the relative positional displacement of a mask A and a wafer B within the range of the half pitches of a diffraction grating. The resolving power of + or - quaternary diffracted light is increased by quadruple to that of + or - primary diffracted light.

Title: Xenon gas discharge lamp
Inventor: AIZAWA MASANORI
IPC: H01J61/067
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To provide a discharge lamp which prevents its center electrode from being loosened because of change in temperature caused by lighting, and has no unevenness in brightness. SOLUTION: A center electrode 6 of a discharge lamp 1 has one external lead wire 5a connected with a metallic pipe 6b, and has the other external lead wire 5a connected with a metallic wire 6c, and the tip end of the metallic wire 6c is inserted into the metallic pipe 6b so as to be freely slid in the inner diameter of the pipe. This constitution thereby prevents the center electrode 6 from being loosened even if temperature is increased because of lighting in addition to change in ambient temperature. Therefore, the xenon gas discharge lamp 1 does not allow the center electrode 6 and an outer electrode 3 to be altered partially in dimension, and its uniform brightness can thereby be guaranteed.

Title: Communication equipment for chromatograph
Inventor: UESAWA IWAO
IPC: G01N30/62
Filed: 1993-04-06
Abstract: PURPOSE:To ADD-convert the currently measuring chromatogram by controlling signals so that signals can be outputted one by one following their priority when the outputting timing of the signals overlap each other and initializing a timer at every prescribed time, and then, by setting the outputting timing of a plurality of signals at an integer multiple of the timing having the minimum interval. CONSTITUTION:A control section 11 controls a counter 3 to output count values and an output control section 6 to output concentration data by using the time of a timer 10 and, when the control to the counter 3 overlaps the control to the section 6, preferentially performs the control to the counter 3. A timer resetting means 12 which initializes the time of the timer 10 whenever the section 11 starts the control to the counter 3 is provided. It may happen that the starting timing of the control to the section 6 and starting timing of the control to the counter 3 becomes the same and the start of the control to the section 6 overlaps the start of the control to the counter 3, since the outputting timing of one signal is an integer multiple of the outputting timing of the other signal. However, even when one timing overlaps the other timing, the overlapping can be eliminated and the currently measuring chromatogram can be A/D-converted, since the control to the counter 3 has higher priority.

Abstract: PURPOSE: To increase strength at low cost and improve quality by making γ-lithium-aluminate almost 4-10 μm in particle size the main ingredient. CONSTITUTION: A magnetic stirrer 2 rotates a magnetic stick 4 by generating a magnetic force by a power supply. It stirs γ-lithium-aluminate and propanol with the magnetic stick 4 and a stirred compound 6 is again stirred after being saturated with ammonia gas. When a reaction progresses completely, sodium metal is added little by little. Chemically processing and sintering γ-lithium- aluminate here makes a particle size 4-10 μm. Control of particle size becomes possible by adjusting a sintering temperature and time; the particle size increases by sintering. After the compound 6 is centrifuged and a precipitate is separated and dried, the above-mentioned particle size is obtained by heat-treating it during a designated time. A matrix plate of high strength is obtained and the quality improves at low cost by making this a main ingredient.

Title: Welding fume exhaust mechanism
Inventor: EHAMA GORO
IPC: F24F7/06
Filed: 1987-04-24
Abstract: PURPOSE:To effectively exhaust a welding fume outside an air inlet circle by providing a welding fume induction mechanism inclined for a working platform face and a duct mechanism by approaching to this inclination rising direction. CONSTITUTION:The welding fume generated by an arc welding ascends a welding work space S in a pyrogenetic particulate and collides with the lower face of an induction cover 6 before being cooled. Since this induction cover 6 forms the lenient inclination at specified angle from a work platform face 2 the welding fume is guided to this lenient slope lower face and slightly moving in the slope rising direction. It is then sucked into the air inlet hood 11 and fed to an exhauster. The welding fume is thus exhausted effectively outside the air inhaling circle of an operator.

Title: Evaporated fuel feeding device for engine
Inventor: KAWAMOTO MINORU
IPC: F02M25/08
Filed: 1988-04-27
Abstract: PURPOSE:To prevent the deterioration of emission and drivability by carrying out the increase and decrease of the purge flow rate, in synchronization with the reversal of the feedback control of the air-fuel ratio. CONSTITUTION:A feeding means for feeding the evaporated fuel into the intake system of an engine, renewal means which renews the purge flow rate of the evaporated fuel by the feeding means into the gradually increasing or reducing direction in staircase form, and a synchronizing means for synchronizing the renewal timing of the purge flow rate to the reversal of the feedback signal are installed. Therefore, the self-complacent increase or reduction of the purge flow rate, disregarding the feedback control, is not carried out, and in the air-fuel ratio feedback control, the disturbance due to the increase or reduction of the purge flow rate can be sufficiently absorbed, and the deterioration of emission and drivability can be prevented.
