Abstract: PURPOSE: To reduce a loss of a circuit and to elevate an efficiency of electric power, by usually switching an electric power source by a pulse width modulation output, and directly applying the electric power source to an electric power amplifying circuit in case when a sound input exceeds a prescribed value.  
     CONSTITUTION: Sound inputs I n  are amplified by buffer amplifiers 22, 23, voltage amplifiers 24, 25 and electric power amplifiers 30, 31, respectively. Subsequently, only a positive wave of each sound signal and only a negative wave are detected by rectifying circuits 34, 35, and rectifying circuits 38, 39, respectively. In the positive wave side, outputs of the rectifying circuits 34, 35 are inputted to a PWM modulating circuit 37 through a low-pass filter 36, are amplified by a pulse amplifying circuit 42, and electric power of a positive electric power source 43 is switched by a main controlling circuit 44. An output of this main controlling circuit 44 is provided to the electric power amplifying circuits 30, 31. Also, when a sound signal has exceeded a prescribed value, operation of the PWM modulating circuit 37 is stopped by an output of a signal detecting circuit 52, voltage of the positive electric power source 43 is directly applied to the electric power amplifying circuits 30, 31. In this regard, the negative wave side is also operated in the same way.

IPC: B60Q1/44
Filed: 1988-04-22
Abstract: PURPOSE: To provide a device capable of making a response corresponding to an event with light energy in real time by applying a pulselike electric signal having the pulse repetition frequency variable in response to the size of the event. CONSTITUTION: This device is constituted of a light source 10, a power source 20 and a pulse generating circuit 16 generating pulselike electric signals having a pulse repetition frequency variable in response to the size of the event. The power to be supplied to the light source is controlled by the pulselike electric signal, so that intensity of the light energy is varied corresponding to change of the size of the event as well as varied in real time. For instance, assuming that the light source 22 is a brake lamp of a vehicle, and the event is the brake- pedal depression by an operator of the vehicle, the pulse repetition frequency of the pulselike signal becomes a maximum when the brake-pedal is depressed and the power is successively supplied to the brake lamp, and when the foot of the operator is released from the brake pedal, the pulse repetition frequency of the pulselike signal becomes a minimum and the power is not supplied to the brake lamp. In this way, the light can be made to respond to the event in real time.

Title: Waveguide type optical switch
Inventor: OTA YOSHINORI
IPC: H04B10/00
Filed: 1987-04-21
Abstract: PURPOSE:To prevent the characteristic of the fitted switch from depending on a polarized light state of incident light by providing an optical waveguide for constituting a directional coupler by allowing the light transmission of the directional coupler to be equal to the C axis of a crystalline plate, diffusing an impurity onto the whole surface of a substrate,, and thereafter, performing ion exchange to other part than the part which is used as a channel, from the surface of the substrate. CONSTITUTION:As for this waveguide, its equivalent refractive index is almost equal to both waves of a light wave mode, therefore, the complete coupling length when a directional coupler is constituted is equal to both waves. Accordingly, when length of the directional coupler is set in advance so as to be equal to this complete coupling length, in a state that no voltage is applied between electrodes 4 and 5, the incident light 6 is all coupled with a waveguide of 2 and emitted. Also, as for an electro-optical constant related to a fact the generating a variation of the refractive index by applying electric field, it is equal as r22 in both waves, therefore, a method for a variation of the coupling luminous intensity in accordance to voltage application is equal and by an equal voltage, a switch state of light, namely, TE and TM are all emitted from a waveguide 3. In such a way, a switch whose characteristic does not depend on the polarized light state of incident light.

Title: Plate transport device
Inventor: KIDA SHIGENOBU
IPC: B21D43/24
Filed: 1980-07-18
Abstract: PURPOSE: To assuredly take out only the uppermost plate and transport it by rocking a plate adsorbing means up and down in a wave-form track portion to prevent double feeding.  
     CONSTITUTION: An advancing motion of a first reciprocating means 10 causes plate adsorbing means 18 to descend, and the top surface of the uppermost plate (a) stacked on a truck is adsorbed by an adsorbing pad 19. Then, a retrerting motion of the first reciprocating means 10 forces a sliding substance 23 to be brought into contact with a track 13, and after that, a second reciprocating means 12 is reciprocated to lift up the plate (a) absorbed by the pad 19 and move it forward. At this time, in a wave-form track portion 13a of the track 13, the plate adsorbing means 18 is rocked back and forth. This rocking motion forces the plate (a) to separate from a plate vacuum adsorbed on the plate (a), so only one plate (a) adsorbed on the adsorbing pad 10 is transported to a feed roller 14.

Title: Fault detection control system
Inventor: HAMURA YOSHIHIRO
IPC: G11B20/18
Filed: 1981-06-26
Abstract: PURPOSE:To releave the case when a demodulating system can have a normal operation and to prevent the deterioration of the efficiency of operation, by ignoring a data error of the demodulating system when an output is produced from a data missing detector of a synchronizing system due to the data missing. CONSTITUTION:When a detecting output is produced from a data missing detector 13 of a synchronizing system due to the data missing, an AND gate 21 is closed via an inverter N. Thus the data error of a demodulating system produced from a data read error detector 12 is cut off and ignored. Accordingly the case when the synchronization is secured after the data missing and the demodulating system can have a normal operation can be relieved to prevent the deterioration of the operating efficiency. Thus a fault which causes the above- mentioned deterioration when the data of a magnetic disk is demodulated is detected, and this detection is controlled.

Title: Rapid quantitative analysis of green sand mold-containing active clay-component
Inventor: MADONO OSAMU
IPC: B22C1/00
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To make it possible to discriminate and quantitatively analyze total active clay and deteriorated clay by suspending a sample in water, dispersing an active clay-component into the water and settling another components, thereby separating the active clay-component. SOLUTION: The sample is fired at 400 to 500 deg.C and a specified quantity of the sample is put into a vessel into which hot water is poured to disperse the clay and to prepare a suspension. The suspension is rested still and is separated to a precipitate and a dispersion. The dispersion of the upper part is discarded and the precipitate is heated, dried and metered. The weight loss- component for the specified quantity of the sample is determined as an NA bentonite quantity. As means for separating Na-Bt and Ca-Bt as the essential component of the active clay, the difference between the swellability and suspendability of both is utilized. When the sample is preheated at 400 to 500 deg.C, the Ca-Bt is thermally deteriorated and the swellability thereof is lost. The Ca-Bt is unstable in suspension and settles in spite of dispersion in water.  The Na-Bt has heat resistance, does not lose activity at 500 deg.C, retains the excellent swellability and disperses in the form of colloid into the water.
