Title: Time constant circuit
Inventor: OKAMURA SHIROU
IPC: G11C27/00
Filed: 1979-12-06
Abstract: PURPOSE: To improve the retaining characteristic of a voltage retaining circuit by utilizing complementarity of the voltage rise and voltage down through the use of two capacitors.  
     CONSTITUTION: The change voltage 1 is applied to a capacitor 3 through a memory switch 2 to charge it and, further this charge is sent to a capacitor 4 through the switch 2, a resistance 9. Thus, the terminal voltage of the capacitor 3 and 4 are added by an adder 7 to take out an output 8. In this way, since the voltage down of the capacitor 3 and the voltage rise of the capacitor 4 are complementary, in the synthesized output, the retaining characteristic just after starting retain is good and the excellent retaining characteristic is obtained.

Title: Optical element module
Inventor: KURIMA KAZUNORI
IPC: G02B6/38
Filed: 1995-06-01
Abstract: PURPOSE: To obtain a novel optical element module excellent in productivity while maintaining quality and yield by forming a partially recessed part on at least one surface of the inside surface of a receptacle part and the outside surface of a ferrule. CONSTITUTION: The ferrule 10 used in this optical element module has a groove 10a formed on the circumference near the front end and a collar part 10b formed at the rear end. The resin injected between the ferrule 10 and a sleeve member 1 intrudes into the groove 10a at the time of fixing the ferrule 10 with the resin in a process for producing such optical element module. Even if a sufficient amt. of the resin is injected in such a case, the excess resin stagnates in the groove 10a and does not infiltrate the inside of the housing part of the sleeve member 1. The contact area of the resin and the ferrule 10 is large and the strength of adhesion between both increases. Further, the thickness of the resin layer increases in the part where the resin intrudes into the groove 10a and, therefore, the ferrule 10 is securely fixed.  The collar part 10b stops the advance of the ferrule 10 by coming into contact with the top end of the sleeve member 1.

Abstract: PURPOSE:To detect the presence or absence of pluse with use of no capacitor, by using a digital frequency comparator which receives the application of a pulse having a lower frequency than the detected pulse at the input terminal of one side. CONSTITUTION:A digital frequency comparator 10 produces the 1st DC level output when the frequency of the pulse signal applied to the 1st input terminal A is lower than the frequency of the pulse signal applied to the 2nd input terminal B. Otherwise the 2nd DC level output is produced. Such comparator 10 consists of an RSFF14, D type FFs 15 and 18, inverters 11 and 17 plus an AND gate 16.  Then the pulse signal to be detected is applied to the terminal A; and the pulse  signal of a frequency lower than the detected pulse is applied to the terminal B.  The frequencies of both pulse signals are compared with each other to obtain a  detection output.

Title: Manufacture of epitaxial wafer
Inventor: KANAMORI KATSU
IPC: H01L21/208
Filed: 1985-07-17
Abstract: PURPOSE:To prevent a crystal defect from occurring in a boundary between an Si single crystal wafer substrate of the prescribed specific resistance and an epitaxial layer by heat treating the substrate at the specific temperature range for the prescribed time or longer, and then forming the epitaxial layer. CONSTITUTION:B is added as an electrically active impurity to Si melted liquid 2 in a crucible 1, and an Si single crystal 4 is formed by a Czochralski device 3. At this time the B adding amount is controlled to set the specific resistance of the crystal 4 to 0.02OMEGA.cm or lower. Then, the crystal 4 is cut by slicing to form a wafer substrate 6. Subsequently, the substrate 6 is set in a heat treating unit 7, and is heat treated under the temperature condition of 1,000-1,200 deg.C for 1hr or longer. At this time it is heat treated at the initial stage in an air atmosphere, and at the later stage in a nitrogen or inert gas atmosphere. Thereafter, an epitaxial layer is formed on the substrate 6. According to the manufacturing method, dissolved oxygen near the surface of the substrate 6 is diffused outward to sufficiently reduce the oxygen density. Thus, no crystal defect due to precipitated oxygen occurs.
