Title: Optical fiber gyro
Inventor: NAGAI MASARU
IPC: G01C19/72
Filed: 1982-02-08
Abstract: PURPOSE:To enable the improvement of a detecting sensitivity and stability through  elimination of a bad influence such as the dark current of a photo detector, the drift  of an electric circuit, by a method wherein a phase difference, being odd-numbered  times pi/2, and a phase difference, being different from the former phase difference by  odd-numbered times x, are periodically switched to each other to provide it between  two lights propagating in a reverse direction to each other through an optical fiber. CONSTITUTION:A phase modulator 10 serves to periodically switch light, which enters  a photo detector 4 after passing through an optical fiber 3 clockwisely, and light which  enters the photo detector 4 after passing through the optical fiber 3 counterclockwisely, and periodically switches a phase difference between the two lights between a first  phase difference DELTApsi1=pi/2(2m-1), being odd-numbered times pi/2, and a second phase  difference DELTApsi2=DELTApsi1+pi(2n-1), being different from the first phase difference DELTApsi1 by  odd-numbered times x. Even if a rotary angular velocity is constant, this enables the  output signal component of the photo detector to produce an alternating current, whereby an electric processing is easily conducted, and additionally, the influence such as  the dark current of the detector and a DC drift at an electric system can be relieved, which results in improving a detecting sensitivity and stability.

Title: Temperature controller
Inventor: IKEHARA TAKASHI
IPC: G05D23/19
Filed: 1978-02-21
Abstract: PURPOSE: To secure the safety of material to be heated such as blankets by detecting in advance for the occurrence of abnormal conditions of short circuit wire and breaking of wire of loaded code or the defective connection of connector for stopping conduction of thyristor and heat of heating wire.  
     CONSTITUTION: When the temperature of material to be heated such as blankets which are heated with heating wire 8 is lower than pre-set temperature, transistor 21 is conducting with the signal of temperature detecting circuit 6. In this case, when transistor 23 is set at ON, the heating wire 8 is energized to raise the temperature. When short circuit wire is in breaking, breaking of loaded code, or defective connection of connector is occurred, the base current of transistor 23 is not conducting. This allows the heating wire 8 to stop conducting due to off-condition of transistors 18, 15 and thyristor.

Abstract: PURPOSE:To form a high impurity concentration layer in a part of a semiconductor region, in a self alignment manner, by using a plurality of kinds of impurities whose diffusion coefficients are different for poly Si, a semiconductor substrate, and their interface.

By ion implantation method, N-type As and P are introduced into the poly Si 12A. Stretching and diffusion are performed by heat treatment, and an N<+> type layer 13 is formed in a self alignment manner. In this process, As whose diffusion coefficient is relatively small on the interface between the poly Si 12A and the Si substrate easily remains in the poly Si, and contributes resistance value reduction and prevention of storing capacitance decrease. P easily diffuses into the N<-> type layer 8 and contributes to the formation of an N<+> type layer 13. By this constitution, the storage charge amount of an information storing capacitance element of stacked structure can be increased.

Title: Evaluating method for alignment precision
Inventor: OZAKI KOJI
IPC: G03F1/44
Filed: 1986-01-30
Abstract: PURPOSE:To evaluate alignment precision in both X and Y directions at a glance by determining pattern displacement according to a superposition on any section of a multiple rectangular frame pattern of the intersection section of an X-shaped pattern. CONSTITUTION:An X-shaped pattern 1a is formed at the same time as the formation of one pattern, and a multiple rectangular frame pattern 2a having fine width is shaped so as to be superposed on the pattern 1a at a required fine interval at the same time as the formation of the other pattern. The pattern 1a and the pattern 2a are superposed so that the centers coincide. Consequently, the quantity of displacement of the patterns in the X and Y directions can be determined only by glancing at a superposition on any section of the pattern 2a of the intersection section of the X shape of the pattern 1a. Accordingly, alignment precision in both X and Y directions can be evaluated at a glance.

Abstract: PROBLEM TO BE SOLVED: To easily and efficiently clean a color comparison cell even when incorporated in an automatic continuous measuring apparatus, by cleaning the color comparison cell with a cleaning solution including a polyoxyalkyleneoxide addition nonionic surfactant of a predetermined HLB value. SOLUTION: An effective component of a cleaning solution is a polyoxyalkyleneoxide addition nonionic surfactant poly activator of an HLB value of 12-18. The HLB value is preferably 13-16, a range of which is determined from a view point of a cleaning effect. If the value is out of the range, the effect is worsened. The poly activator can be obtained by adding alkylene oxide to alcohols or phenols. The cleaning method is achieved simply by putting and leaving the cleaning solution into the color comparison cell. A time while the cleaning solution is put and kept in the cell is optical and generally 10 seconds or longer. There is no inconvenience even if the solution is left for a long time.  In general, the solution is preferably held in the color comparison cell within a range where the cell can be cleaned in a sequence with a frequency for automatically measuring a concentration of the anionic polymer being taken into account.
