Title: Position detector
Inventor: TOTSUKA MASAO
IPC: H01L21/68
Filed: 1987-05-06
Abstract: PURPOSE:To detect the accurate relative position of the second element to the first element by a method wherein a reference mark is provided with the relative position to the first element such as a reticle to detect the relative position to the second element such as a wafer etc. CONSTITUTION:A wafer lighting system WL illuminates a wafer WF from a position between a projection optical system PO and the wafer WF with an illuminating light in different wavelength from that of another illuminating light exposing the wafer WF not through the intermediary of the projection optical system PO. The image of wafer WF illuminated by the wafer lighting system WL is picked up by detection optical system after a mirror M1 through the intermediary of the projection optical system PO. The image of wafer WF in the detection optical system is formed on a reference mask BM with already-known relative position to a reticle LT through the intermediary of an aberration correcting optical system OS correcting the aberration due to the light in different wavelength from exposing wavelength passing through the projection optical system PO. Within the optical systems after reference mask BM, attention are paid so that any mark on the reference mask BM and the wafer image may be observed simultaneously. In such a constitution, the relative positions of the reticle LT and the reference mask (reference mark) BM being already-known, the reticle LT and the wafer WF can be aligned with each other by positioning the wafer WF shifting from the reference mark by the position slip of reference mask from the reticle LT.

Title: Method for after-fermentation of culture medium
Inventor: TAMIYA SHIGERU
IPC: A01G1/04
Filed: 1987-05-01
Abstract: PURPOSE:To mass-produce mushrooms of good quality, by allowing a culture medium after completing prefermentation at a high temperature and humidify, reducing temperature of the culture medium stepwise at a high humidity and carrying out after-fermentation. CONSTITUTION:For example, a culture medium after completing prefermentation is allowed to stand at 60 deg.C and 100% humidity for 8hr, then at 55 deg.C and 100% humidity for 2 days, further at 50 deg.C and 100% humidity for 3 days and subsequently at 45 deg.C and 100% humidity for 5 days. Temperature is finally reduced so as to provide 23.5 deg.C and 100% humidity for 3 days to carry out after- fermentation. Since the temperature of the culture medium is reduced stepwise, sterilizing effects are high. Removal of ammonia is improved, since the culture medium is kept at a high humidity to carry out the after-fermentation. Thereby the culture medium is suitable for propagation of mushroom mycelia and productivity is enhanced.

Title: Linear encoder
Inventor: TAKEDA IKUO
IPC: G01D5/26
Filed: 1987-05-01
Abstract: PURPOSE:To enable a scale pitch to be varied and set freely and to easily obtain accurate and high scale resolution by providing an ultrasonic wave vibrator to one end side of a scale so that an ultrasonic wave can be emitted into the scale. CONSTITUTION:The frequency of the ultrasonic wave from the ultrasonic wave vibrator 2 which is emitted into the scale 1 is varied with the driving output of a driving circuit 4. Then the scale 1 made of an acoustic medium functions as a sine wave phase grating with the ultrasonic wave present therein, so incident light from a projection system 5 which is made incident from one flank part of the scale 1 is diffracted by the sine wave phase grating in the scale 1 and projected from the other flank part of the scale 1. The (+1)th-order diffracted light and (-)th diffracted light of the projected light are made to interfere with each other through the interference means of a photodetection system 6 and the interference light is converted by a photodetecting element 6b photoelectrically and outputted from an output circuit 6c. The scale pitch is therefore converted freely and the accurate and high scale resolution is obtained.

Title: Stroboscope
Inventor: SUGIYAMA TAIDO
IPC: G01P3/40
Filed: 1991-02-18
Abstract: PURPOSE:To illuminate a strobe lamp with approximately constant brightness whether speed is high or low by illuminating the strobe lamp for light emission time which has been calculated according to light emission frequency determined by a speed range of an object to be measured. CONSTITUTION:When measurement speed of an object to be measured is roughly determined, the speed is specified in a speed setter 1. Thus the speed setter 1 sets light emission speed of a strobe lamp, that is the number of light emissions per unit time. This number of light emissions is specified to a larger value as the speed increases. A calculator 2 calculates light emission time for one emission according to the number of light emissions. The light emission time is the larger as the number of light emissions decreases. The slower the speed, the longer a light emission frequency T, and light emission time (t) becomes longer accordingly, so that the strobe lamp is illuminated with brightness approximately equal to that at high speed.

Filed: 1984-05-30
Abstract: PURPOSE:To execute stably high speed reproduction of odd times by forming helically a track on a magnetic tape by using a rotary head, and using tracking information used for an automatic tracking (ATF) system. CONSTITUTION:A motor 5 is rotated at a constant speed by converting an output of a frequency generator varied in accordance with a revolving speed of its motor 5, to a voltage by an F-V converter 8, and applying it to a driving circuit 10, and also brought to rotation control so that an output of a tracking detecting circuit 11 is applied to a driving circuit 10 through an adder 9, and heads 1a, 1b execute an on-track to a track recorded on a magnetic tape 12. A speed control loop of the motor 5 works so that an input signal frequency of the F-V converter 8 becomes constant, therefore, when a frequency division of a frequency dividing circuit 7 is 1/N, a rotating speed of the motor 5 becomes N times as high as the regular reproducing time. Even in this case, an output of the tracking detecting circuit 11 is applied to the driving circuit 10 through the adder 9, and the track recorded on the magnetic tape 12 and the heads 1a, 1b are brought to on-track control, as well.
