Title: Wafer alignment
Inventor: TAGUCHI TAKASHI
IPC: H01L21/30
Filed: 1988-04-08
Abstract: PURPOSE:To make wafer alignment with high precision by a method wherein a scaling factor by wafer measurement before resist coating is used as a scaling factor of exposure after resist coating. CONSTITUTION:An alignment mark 21 is formed on a substrate 20 and then several wafers whereon underneath films 22 are formed are prepared. The positions of a few wafer alignment marks 21 out of several wafers are measured to calculate the scaling factors. The mean value of the scaling factors is calculated to set up the scaling factor to be adopted. Next, a resist coating process is performed. The resist exposure is performed using the scaling factor to be adopted. Then, the position detecting error of the alignment mark 21 is avoided enabling the wafer alignment to be made with high precision.

Title: Temperature measuring unit
Inventor: ONO KOUZOU
IPC: G01K11/12
Filed: 1979-07-10
Abstract: PURPOSE: To obtain a temperature measuring unit which is small size and does not receive electromagnetic induction, by providing a temperature sensing material consisting of thermochromic materials in the light path of optical fibers and by receiving the emission light of this temperature sensing material through the optical fibers above by a photoelectric conversion element.  
     CONSTITUTION: When arrow-direction incident light A is incident onto optical fiber 3 from the light source which is not shown in the figure, this incident light A becomes a parallel ray by rod lens 2 and enters temperature sensing material 1 and is condensed by rod lens 2a after reflected once in temperature sensing material 1 by both orthogonal faces respectively and is emitted as emitting light B through optical fiber 3a. Consequently, if temperature sensing material 1 consists of thermochromic materials related to transmittivity, the ratio of intensity of emitting light B to incident light A is dependent upon the temperature because the transmittivity changes due to the temperature, and specially, intensity of emitting light B itself is dependent upon the temperature if intensity of incident light A is fixed.

Abstract: PURPOSE:To obtain a culture medium raking-out device capable of scraping off all culture medium in a culture bottle while preventing rotation of culture medium by providing two raking-out blades capable of rotating in the opposite direction while differentiating rotating area. CONSTITUTION:When a culture medium 20 in a culturing bottle 21 is raked out using the above-mentioned culture medium raking-out device, a raking-out blade 1 inserting from the mouth of bottle kept in inverted state is moved upward while scraping the culture medium 20 by rotating the raking-out blade 1.

Rotation of the culture medium 1 can be prevented by the blade 2 rotating in the direction opposite to the blade 1 even when the culture medium 20 is contracted and rotated with the blade 1 and the culture medium 20 can be scraped off without lowering scraping-off rate of the culture medium.
