Title: Detection device
Inventor: KASAI EIJI
IPC: G01V3/10
Filed: 1997-05-09
Abstract: PROBLEM TO BE SOLVED: To eliminate the influence of an installation environment by preventing detection sensitivity from being lowered by providing a sensor part with two resonance capacitors and using a balance circuit for which the respective capacitors are respectively connected to both the terminals of the detection coil. SOLUTION: A sensor part 20 is equipped with a detection coil 22 wound around a core 21 and the real number of transformers 24. Concerning the sensor part 20 for this detection device, resonance capacitors 23a and 23b are respectively connected between both terminals A and B of the detection coil 22 and between both terminals (a) and (b) of the winding wire 24a on the primary side of real number transformers 24, and the sensor part 20 is made into a balance circuit. Since the sensor part 20 is constituted as the balance circuit like this, concerning a current I to flow through a resonance circuit, any in-phase leak current does not flow to the ground. Therefore, the range of detection is made uniform without being affected by the ground or the environment, detection sensitivity is improved and high-accuracy measurement is enabled.

Title: Protective circuit for dot printer
Inventor: AYA HIDEAKI
IPC: B41J29/46
Filed: 1978-09-26
Abstract: PURPOSE:Standard protective circuit of which maintenance and inspection can be facilitated and which can prevent a solenoid from being lost by burning provided with a voltage shut-off means installed between a power supply and a drive circuit for use in shutting off the power supply voltage to be applied to a solenoid in reference to an output from means for discriminating the voltage. CONSTITUTION:Power supply voltage +Vp is applied to the solenoids 141-147 via collector-emitter of the transistor 293. For example, under the transistor 261 got trouble and the emitter voltage showed an extreme high value, the Zener diode 281 and the thyrister 292 are made to be conductive to cause the base of the transistor 293 to be short circuited to the ground. Thereby, the transistor 293 is caused to be non-conductive to shut off the power supply voltage +Vp applied to the solenoids 141-147. The thyrister 292 can hold the situation to protect the solenoids 141-147 and the transistors 261-267.

Title: Coated steel stock having resistance to discoloring and corrosion
Inventor: OKITA MASAKAZU
IPC: B32B15/08
Filed: 1988-05-16
Abstract: PURPOSE:To eliminate the deterioration of physical properties even after using for a long period of time, by a method wherein the surface of a steel stock is coated by a polyolefin resin layer, containing coloring agent, sulfide anti- oxidizing agent, ultravioret ray absorbing agent and/or carbon black, which are having predetermined weight %, through a bonding layer. CONSTITUTION:The surface of a steel stock is coated by a polyolefin resin layer, containing 0.05-5wt.% of coloring agent, 0.005-0.5wt.% of sulfide anti- oxidizing agent, ultraviolet ray absorbing agent and/or carbon black, through a bonding layer. 4,4'-thiobis (3-methyl-6-tert-butylphenol), thiobis(beta naphthol) or the like, for example, is employed as the sulfide anti-oxidizing agent. Such sulfide anti-oxidizing agent is added to affect on hydroperoxide or an intermediate body in ultravioret layer deterioration upon using it under exposing it outside of a house and stabilize it thereby improving the weather-proof property of the steel stock. When it is less than 0.005wt.%, there is no sufficient effect but when it exceeds 0.5wt.%, the effect thereof is not changed, however, spoiling the economical property of the coating.

Title: Voice recognizing telephone set
Inventor: KAMEI SHOICHI
IPC: G10L15/28
Filed: 1989-05-12
Abstract: PURPOSE:To avoid an undesirable influence for the operation caused by an erroneous recognition result of a first step by bringing an operation command of a telephone set to voice input, setting the time until the next operation command is brought to voice input to a waiting state, and nullifying a recognition result of an operation command voice, when this time exceeds a prescribed time. CONSTITUTION:After a recognition result obtained by bringing an operation command of a telephone set to voice input is stored in a recognition result store part 5, the time until this recognition result is conformed, or the next telephone set operation command is brought to voice input is set to a voice input waiting state. In this state, when a voice input waiting time measured by a time measuring part 8 exceeds a prescribed time, the recognition result of the telephone set operation command voice of the recognition result store part 5 is nullified. Accordingly, since a recognition result of a first step can be nullified forcibly, there is no fear that an erroneous recognition result by a first step becomes effective by a noise input in a voice input waiting state of a second step. In such a way, such inconvenience as a malfunction state caused by the erroneous recognition result in a first step is continued is avoided.

Title: Magnetic tape device
Inventor: ITOU MASAO
IPC: G11B15/10
Filed: 1981-07-31
Abstract: PURPOSE:To attain stable operation, by releasing the transmission between an operating member and a cam even under the pressing operation of a head and avoiding the transmission between them from being released, even if the operation of the operating member is released during the tape running direction conversion. CONSTITUTION:In loading a cassette to a device during nonoperation as shown in figure, a release plunger 13 is energized, a stopper member 12 is turned counterclockwise to turn a cam 5 counterclockwise via a spring 11 and a roller 10 and an operating member 16 presses a head 19. When the power application to the releasing plunger 13 is disconnected, the transmission between the cam 5 and the member 16 is released with a control member 22 even during the pressing position and on the way of pressing. Through the driving of the cam 5 and the member 16, the running direction of a tape is switched with a switching member 7. While the member 7 is in operation, even if the operation of the member 16 is released, the transmission between the cam 5 and the member 7  can not be released. Thus, unstable state can be prevented and the tape is run  with a stable state.

Abstract: PURPOSE:To record stereoscopic image information in an easily utilizable form by recording separately moire pattern information and object information. CONSTITUTION:An image of an object to be photographed on which a moire pattern is superposed is brought to image pickup to an image pickup device 9 which is placed in the rear of a screen 8. Also, an image of an object to be photographed on which an image of a lattice pattern 3 is superposed is brought to image pickup to an image pickup device 12 which is placed on a reflected light path of a half mirror 11, and a signal of the image of the object to be photographed is outputted by a filter 13. By subtracting an output signal of the filter 13 from an output signal of the device 9, moire pattern information is extracted. By recording separately the output signal of the filter 13 and an output signal of a subtracting circuit 14, information of the object to be photographed and moire pattern information can be recorded separately. In such a way, one information is read out arbitrarily, and it is prevented from overlapping of two images to each other and going an image to indistinct. Also, only the moire pattern information is read out arbitrarily, and an analysis of a moire pattern by a computer is executed easily.
