Title: Position detector
Inventor: TATENO HIROTAKA
IPC: G03F9/00
Filed: 1986-06-25
Abstract: PURPOSE:To enhance alignment accuracy, by using the change in spatial frequency, which is obtained from a diffraction lattice mark wherein a pitch changes continuously or discontinuously, in alignment. CONSTITUTION:A diffraction lattice mark 13 wherein a pitch changes continuously is preformed on a wafer 10. Next, sheet like spot beam SP is allowed to irradiate the wafer 10 and, when a stage 11 or alignment irradiation beam 1 is moved to allow the relative positional relation between the mark 13 and the alignment irradiation beam 1 to change in an X-axis direction as shown by an arrow 22, the diffracted beam present at the position corresponding to the mark pitch of a pupil surface changes positionally corresponding to the continuous change in the mark pitch. This change is detected corresponding to the positional relation between a time axis or the stage 11 and the irradiation beam 1 to calculate the change of + or - unidimensional curves 14a, 14b on the pupil surface and, on the basis of the change calculated, a signal processing part 6 detects that the change comes to a predetermined state and the position corresponding thereto is calculated. By this method, alignment becomes easy and the enhancement of accuracy can be achieved.

Title: Temperature control method for electric carpet
Inventor: YOSHIOKA HIDEKAZU
IPC: F24D13/02
Filed: 1991-06-19
Abstract: PURPOSE:To recover the delay of the rise in the surface temperature of a carpet, etc., on a human-body contact side by making a shift quantity larger as the rising rate of detected temperature in the vicinity of a heater is high and making the shift quantity larger as room temperature is lowered. CONSTITUTION:When the power source is turned on with a power switch S1, a rapid heating mode judgement part 84 judges a rapid heating mode and outputs a mode signal to an energizing control part 85. The energizing control part 85 sets in-mode 1st OFF temperature T1 to the value obtained by adding the shift quantity  S to set OFF temperature To. This shift quantity is calculated according to the detected temperature rise rate KT in the vicinity of the heater 2 and the room temperature TR. The installation conditions of the electric carpet A are sufficiently considered, so comfortable rapid heating is enabled regardless of the differences of the installation conditions. When the detected temperature rising rate KT in the vicinity of the heater is high after the power source is turned ON, the temperature of the carpet 11 rises slower than the temperature on the side of the heater 2.

Filed: 1989-06-09
Abstract: PURPOSE:To prevent the sticking of scale, slime, etc., and formation of rust in piping and to supply always clean washing water by equipping an ionizing device to a pipe for the water to be used in the unit. CONSTITUTION:The dental diagnosing unit A consists of a diagnosing chair 1 and its junction box 2. The ionizing device B is housed in the junction box 2.

The other end thereof is connected to the water feed piping 3 via the junction box 2 and is connected to a cup water feed port 4, a turbine 5 and a syringe 6 attached to the diagnosing chair 1. A cylindrical electrode 9 made of aluminum constitutes the negative electrode of the ionizing device B and a bar-shaped electrode 10 made of carbon constitutes the positive electrode. Since both the electrodes 9, 10 are respectively formed of the materials of the electrochemical potentials different from each other, a sort of battery is formed when water 13 exists in the space in the electrodes 9, 10. As a result, the ionization of the water is accelerated and the sticking of slime and the formation of rust are obviated.

Title: Discriminating method for quality of nc command tape
Inventor: TANAKA YUTAKA
IPC: G05B19/4069
Filed: 1980-10-22
Abstract: PURPOSE:To check the fine part of an NC command pattern by setting coordinates of an optional point in a pattern, drawn by NC commands, in a pattern-display enabling region, and performing the specification of the magnification of the pattern and the calculation of the coordinates of a pattern drawing origin. CONSTITUTION:an optional point P1 in a pattern to be drawn by NC commands is inputted and set in the center of a plotter form 26 or on externally specified coordinate. Then, the specified coordinates and magnification are used to calculate the coordinates of a starting point SP for pattern drawing, and a pattern 28A is drawn, by NC commands, on the form 26 taking the coordinates of the SP as an origin with the specified magnification. When the coordinates of the SP is outside of the form 26 or when the trace of the pattern goes out of the form 26, the pen tip of a plotter is made to stary at the external edge of the form 26, thus drawing the pattern only when the pen tip is inside of the form 26. The functions of performing the said operation are added to an NC tape generation device to draw the pattern 28A of a fine part A on the form 26, centering on an optional point in the pattern 28, with optional magnification, thereby discriminating whether NC commands are generated on the NC tape correctly.

Title: Electrostatic charger
Inventor: MUKAI HIDEO
IPC: G03G15/02
Filed: 1980-10-22
Abstract: PURPOSE:To decrease electrical damages of a photoreceptor and prolong its life by making the resistance value of a contactor of an electrostatic charger large on the side contacting the body to be electrostatically charged first and small on the opposite side. CONSTITUTION:A contactor 28 and an electrode 29 are mounted on the front part of an electrostatic charger base 24 successively from the front surface thereof, that is, the side in contact with a photoreceptor 4. The contactor 28 is bisected to a front stage 28a and a rear stage 28b in the rotating direction of the photoreceptor 4, and has a regulated resistance value. The electrode 29 is constituted of conductive rubber, to which an AC power source 32 and a DC power source 33 are respectively connected. When AC voltage and DC voltage are applied from the electrode 29 in accordance with the rotation of the photoreceptor 4, the peak of the inflow current to the body to be electrostatically charged decreases because the front stage 28a of the contactor 28 is set larger in contactor resistance than the rear stage 28b. With such constitution, the electrical damages of the photoreceptor as the body to be electrostatically charged are decreased and the life of the photoreceptor is prolonged.

Abstract: PURPOSE:To prevent an increase of exhaust temperature, by providing a temperature sensor in an exhaust system and retarding the actuated timing of an exhaust valve in accordance with an output of the sensor when the exhaust temperature exceeds a predetermined value. CONSTITUTION:An exhaust passage 49 provides an exhaust temperature sensor 53, and its output is input to a controller 55.

The temperature of combustion gas in the exhaust system decreases because the combustion gas is discharged in a more expanding condition from a combustion chamber by retarding the opening timing of the exhaust valve 17. A control device gives no particular influence to the action of an exhaust purifying device while no bas effect also to economical efficiency.
