Title: Light modulation circuit
Inventor: TAJIMA TSUTOMU
IPC: H04B10/2507
Filed: 1986-09-22
Abstract: PURPOSE:To keep the modulation amplitude of a low frequency analog signal at a constant level, and to stabilize a modulation factor, by keeping the amplitude of the low frequency analog signal at the constant level, in a light modulation circuit in which the low frequency analog signal is superimposed on a digital main signal. CONSTITUTION:In the light modulation circuit having a light emitting element driving circuit 1 that outputs a light signal on which the low frequency analog signal is superimposed for the amplitude of a light digital main signal to be inputted to a terminal 10, an LPF4 extracts the low frequency analog signal from the output of a light receiving element 3. The peak value of the signal is detected at a peak value detection circuit 6. After the detected voltage is compared with a reference voltage in a gain control signal generation circuit 7, the circuit 7 outputs a control signal to an amplifier 8 that is a gain variable amplifier, and applies a DC negative feedback on the circuit 1 so as to compress a difference between the above stated reference voltage and a peak value detecting voltage, and thereby, gain control is performed. Therefore, a new low frequency analog signal inputted from a terminal 11, after the amplitude being controlled, is superimposed on the main signal at the circuit 1. In this way, the modulation amplitude of the analog signal can be kept at the constant level.

Title: Power source
Inventor: OOTA TOMOICHIROU
IPC: H02M3/28
Filed: 1989-09-01
Abstract: PURPOSE:To obtain a power source in which a detector is not damaged by providing an overvoltage detecting coil to be magnetically coupled to a smoothing choke coil of the secondary side of a converter transformer, and controlling an overvoltage protective operation in response to a detected voltage to be induced in the detecting coil.

A voltage generated from a detecting coil CH2 is raised proportionally thereto, and a signal voltage to be applied to a Zener diode ZD1 is also raised. Then, the Zener voltage of the diode ZD1 is increased to be larger than the voltage generated from the coil CH2 at the time of normal operation to protect it against the overvoltage at the time of generation of the overvoltage.

Abstract: PURPOSE:To obtain a magnetic head superior in wear resistance by approximately linearly forming metallic magnetic films at an angle to the magnetic head running direction. CONSTITUTION:Magnetic core half bodies I and II where a metallic magnetic film 1 is interposed between a pair of guard materials 2 and 3 are butted, and a magnetic gap (g) is constituted between butting faces. Winding grooves 4 and 5 are formed in core half bodies I and II respectively, and coils are wound around these grooves to supply/take out signals to/from a head. Metallic magnetic films 1 are multilayered films where thin films made of a high-permeability material like 'Sendust(R)' are laminated with an insulating film between them, and guard materials 2 and 3 are made of ferrite. End faces on the sides opposite to the gap (g) forming sides of metallic magnetic films 1 are so cut that they slightly stand back from side faces of magnetic core half bodies I and II, and end parts are filled with glass 8. Since the extension direction of magnetic films 1 is made nonparallel with the tape sliding direction of the magnetic head, a proportion occupied by the magnetic films 1 on the tape slide face is considerably reduced.

Filed: 1990-08-28
Abstract: PURPOSE:To uniform the distribution of back flow on the blade outer peripheral part side and reduce interference noise generated with a thing placed behind the blade by providing a ventilation flue of specific shape inside each of plural blades. CONSTITUTION:An axial fan is formed of a shaft part 1 fitted in relation to a driving shaft and plural blades 2 protruding radially at the specified spaces from the peripheral surface of the shaft part 1. Inside each blade 2, there is piercingly provided a ventilation flue 5 inclined from the blade inner peripheral part toward the outer peripheral part, with a take-in port 3 opened at the blade face tip part and a blow-off port 4 opened on the rear end side. The take-in port 3 of each ventilation flue 5 is to be parallel to the blade front edge, whereas the blow-off port 4 is tilted frontward in the rotating center direction in relation to the blade rear edge line. Secondary flow is thereby blown off into the outer peripheral direction from the blow-off port 4 of the ventilation flue 5 so as to restore the boundary layer of the outer peripheral part, and this inclined blow-off port 4 of the ventilation flue 5 allows secondary flow to be blown-off successively from the outer peripheral part where the boundary layer is easily developed so as to lessen the flow speed loss of the back flow.
