Title: Measuring apparatus
Inventor: KAMIYA SEIICHI
IPC: G01B11/24
Filed: 1994-06-08
Abstract: PURPOSE:To measure the shape of an optical member highly precisely. CONSTITUTION:The luminous flux emitted from a laser light source 31 is divided into two luminous fluxes having mutually different planes of polarization and frequency difference. The luminous fluxes irradiate a material B to be measured and a reference plane mirror 46. Two luminous fluxes reflected from the material B to be measured and the plane mirror 46 respectively are synthesized by a polarization beam splitter 42 and reflected upward. Thus, the beat signal is obtained in an ID camera 50 and photodetectors 52a-52b. A phase meter 53a obtains the phase difference of the beat signal obtained by the ID camera 50 and the photodetector 52a. The shape of the material B is computed as the spherical aberration based on the value. The phase differences of the beat signals obtained by the photodetectors 52a and 52b-52d in phase meters 53b-53d are obtained, respectively. The measured value is corrected based on the values.

Abstract: PURPOSE:To contrive to offer rapidly an MROM required by users by a method wherein impurity ions are implanted to the arbitrary region of a semiconductor element from the upper part of the semiconductor element completed with metal wiring, and after then the impurity ions are activated electrically according to microwave heating. CONSTITUTION:Impurity ions are implanted selecting the region 6 of a part of semiconductor elements 7, 8 formed with metal wiring layers, and after then by performing microwave heating, impurity ions thereof are activated to store informations to the semiconductor elements 7, 8. According to microwave heating, because the region implanted with impurity ions can be heated selectively, melting or the loss of the metal wiring is not generated. Because impurity regions can be formed selectively in the specified regions of the semiconductor elements 7, 8 even after completion of the metal wiring process like this, turnaround time of a semiconductor memory unit such as a mask programmable ROM (MROM), etc., can be shortened utilizing the fact thereof.

Title: Contact aeration type sewage treatment apparatus
Inventor: MATSUMOTO JURO
IPC: C02F3/00
Filed: 1996-05-22
Abstract: PROBLEM TO BE SOLVED: To prevent the lowering of treatment function while reducing the labor in maintenance and control. SOLUTION: When a water level difference detection means detects the rise of the water level of a contact material region 21 with respect to the water level of a reference region, an electromotive changeover valve 33 stops aeration operation to change over the same to backwashing operation. That is, the closing (or narrowing) of passages between contact materials is automatically detected to automatically perform backwashing operation and, therefore, the flow of sewage between the contact materials is improved not only to prevent the lowering of the treatment function but also to perform automatic backwashing operation and, therefore, the labor for maintenance and control can be reduced. Further, an existing sewage treatment apparatus can be used as it is.
