Title: Scherbius apparatus enabling continuous operation in case of instantaneous power failure and instantaneous lack of phase
Inventor: KUGE KATSUTAROU
IPC: H02H3/00
Filed: 1978-05-31
Abstract: PURPOSE: To accomplish stable continuous operation by ensuring separate actions to remedy instantaneous power failure and instantaneous lack of phase by means of two separate circuits to handle the respective troubles.  
     CONSTITUTION: In the normal operation, a power supply breaker S 1  in the on state, a switch S 2  in the off state, a high speed breaker S 1  is in the on state and an inverter SCR in the conduction state. Upon reception of the instantaneous power failure signal, the inverter SCR starts the reduction of the gate and then, cut the inverter SCR the moment the inverter current is down zero. The generation of the phase lacking signal triggers simultaneous production of an off command of the power supply breaker S 1 , a gate resuming command of the thyristor switch S 2 , a gate reducing command of the inverter SCR, and an on command of the high speed breaker S 3 . With the inverter SCR turned off, the high speed breaker S 3  opens quickly.

Title: Magnetic head
Inventor: KAMIOKA TOKIO
IPC: G11B15/62
Filed: 1988-03-22
Abstract: PURPOSE:To prolong the service life of a magnetic head and, at the same time, to stabilize the movement of magnetic tapes by constituting the dummy sliding section of the head of a material having a wear resisting property stronger than that of the material constituting the head core. CONSTITUTION:A tape sliding surface 2 is constituted of head cores 3 and 4 and a dummy sliding section 5A provided between the head cores 3 and 4 and a nonmagnetic or magnetic material having a wear resisting property which is stronger than that of the material constituting the head cores 3 and 4 against magnetic tapes is used for forming the dummy sliding section 5A. Therefore, even in a worn out state of this magnetic head, wear of the dummy sliding section 5A is a little and, microscopically, selective wear sigma1 of the section 5A is hardly recognized. The very little selective wear of the dummy sliding section 5A means that occurrence of vibrations caused by the selective wear of the section 5A when a magnetic tape is moved can be prevented. Therefore, the average service life of this magnetic head can be extended several times and the wow flatter can be suppressed to 0 dB practically.

Filed: 1994-03-11
Abstract: PURPOSE:To suppress fluctuation in the low threshold level read out current of a memory transistor by discharging electrons stored in a floating gate and then injecting hot electrons into the floating gate from the source region side thereby converging the low level threshold level to a predetermined level. CONSTITUTION:As an erasing operation for discharging electrons stored in the floating gate 3 of a memory cell, a negative voltage is applied to the control gate electrode 5 thus causing Fowler Nordheim's tunnel discharge of electrons from the channel region between the source 7 and drain 8 to a P-type semiconductor substrate 1 through a first gate insulating film 2. Subsequently, the low threshold level is controlled. In other words, a voltage is applied to the control gate electrode 5 and the drain 8 thus injecting hot electrons from the source 7 into the floating gate 3. Consequently, the threshold level is converged after injection regardless of the initial level.

Abstract: PURPOSE: To enable only the page to be turned over to be surely turned over by performing page-turning with a friction roller while pressing the suitable positions  between the positions where friction rollers contact and the seam.  
     CONSTITUTION: This is the device of automatically turning over the printing pages of a pass book comprising binding plural sheets of printing pages at the seam, wherein a movable lever 34a approaches to the pass book 1 having been accepted by a guide plate 10, conveyed up to the specified position and stopped, and when a support lever 20 goes apart from the pass book 1, a revolving friction roller 13a touches the page of the pass book 1 and turns upward its end edge to the seam 4 side. At this time, a lever 51a operating pin 53a abuts against a contact member 55a, causing a pass book pressure plate 52a to press the position about 5 mm apart from the seam 4. As a result, this page and the subsequent pages become stiff and difficult to turn over and therefore only the uppermost page is forcefully turned over by the friction roller 13a.

Title: Voice recognizing device
Inventor: KANEKO KAZUMA
IPC: G10L15/06
Filed: 1989-03-16
Abstract: PURPOSE:To attain a high recognition rate without receiving the influence of ambient noises by generating noises by a noise generating means at the time of registration and comparing a standard voice characteristic pattern with a previously recorded input voice characteristic pattern in the same environment as the environment at the time of recognition, and thereby recognizing the above-mentioned pattern. CONSTITUTION:A white noise signal generating section 3A generates a white noise electric signal N by receiving the instruction signal CN from a control section 2A when a switch 1 for registration is pushed. A speaker 4 converts the signal N to the white noise and outputs the same. The white noise is thus superposed on the voice of a specific speaker. This voice is passed through a microphone 5 and an analyzing section 6 and is thereby made into the standard voice characteristic pattern which is stored in a memory 7 for the standard pattern. A recognition mode is automatically started after the end of the registration. The voice inputted from the microphone 5 in the state of not operating the white noise signal generating section 3A and the speaker 4 is set through the analyzing section 6 and a memory 8 for the input pattern to a recognition section 9 where the voice is compared with the standard voice characteristic pattern and the inputted voice pattern is recognized. The influence of the ambient noises is eliminated in this way and the high voice recognition rate is attained.
