Title: Optical signal deterioration detection circuit
Inventor: SUGIYAMA SHIGEHISA
IPC: H04L25/02
Filed: 1994-08-30
Abstract: PURPOSE: To quicken the transfer of an optical signal deterioration alarm and to suppress the transmission of an undesired signal to a post-stage circuit and the effect of an warning by detecting missing of clock or frequency fluctuation caused at the initial stage of occurrence of deterioration in an optical signal. CONSTITUTION: A received optical signal 11 is converted into an electric signal by a light receiving element 12, and a transmission line clock signal 32 is extracted through a band-pass filter 17 and a limiter amplifier 31. The phase of the extracted transmission line clock signal 32 is compared with a phase of a reference clock signal 33 with a prescribed period by a phase comparator circuit 34. The deterioration in the optical signal is detected by the result of phase comparison. That is, an output fault of the transmission line clock signal is directly monitored by comparing a change in phase difference between the transmission line clock signal 32 and the reference clock signal 33.  Since missing clock or fluctuation in the clock frequency of the transmission line clock signal 32 caused at the initial stage of the occurrence of deterioration in an optical signal is directly monitored, the optical deterioration state is detected early to quicken transfer of an alarm.

Title: Apparatus for controlling revolutional speed of fan
Inventor: OKADA KAZUHIKO
IPC: F23N3/08
Filed: 1988-08-18
Abstract: PURPOSE:To gradually accelerate the revolutional speed of a fan and to prevent noises from generating due to a rapid change in the revolutional speed by providing a time function generation means and setting the revolutional speed in a multi-staged manner from a low speed to a high speed. CONSTITUTION:A first preset speed at a low speed optimum for igniting a gas burner 12 is set, and a motor 3 interconnected to a blower 1 is driven at the first preset speed through a motor drive circuit 59. When a solenoid valve 33 is opened through a valve actuation circuit 39 and ignition to the burner 12 is ascertained by an output signal released out of a flame detection circuit 42, a second preset speed optimum for gas combustion is selected and a timer 71 is reset. Then, the time 'm' of the timer 71 is read, and the time 'm' is substituted for a time function f(m) to calculate and output a revolutional speed. The time function f(m) shows a gradual change in speed from the first preset speed to the second preset speed, and the motor 3 is driven on the basis of the revolutional speed preset by f(m). When the stopping of water feed is ascertained by an output signal released out of a water stream detection circuit 55 under a hot water feeding condition, the solenoid valve 33 is closed through the valve actuation circuit 39 and the drive of the motor 3 is stopped through the motor drive circuit 59 to return to a state capable of feeding hot water.

Title: Manufacture of semiconductor superlattice
Inventor: ITO NAOYUKI
IPC: H01S5/00
Filed: 1986-09-01
Abstract: PURPOSE:To manufacture a thin film of high quality in a mass production by using an additive combined by dialkyl zinc, dialkyl sulfur or dialkyl selenium, and forming a thin zinc sulfide film and a thin zinc selenium by an organic metal vapor thermal decomposing method using hydrogen sulfide and hydrogen selenium. CONSTITUTION:The quantity of lower boiling point of R2Zn, R2S and R2Se is excessively mixed, reacted and ripened by heating, and excessive component is then distilled to be removed to synthesize the additive. The dialkyl zinc is formed with dialkyl sulfur or dialkyl selenium to form an additive to remarkably reduce the reactivity as a Lewis acid. Thus, even if it is coexisted with hydrogen sulfide or hydrogen selenide near at room temperature, its reaction is not advanced at all. When the additive introduced into a reaction furnace 1 arrives at a heating zone near the substrate 3, it is ionized to generate dialkyl zinc, which is reacted with hydrogen sulfide or hydrogen selenide, thereby growing a thin film. Thus, the formation of fine particles of ZnS, ZnSe is suppressed and a thin film of high quality is grown.
