Title: Self-protection type semiconductor device
Inventor: KONISHI NOBUTAKE
IPC: H01L31/111
Filed: 1984-03-19
Abstract: PURPOSE:To obtain a photodrive type thyristor which can always obtain an effective protecting operation by introducing a light to the portion of a depletion layer generated only when the forward voltage arrives at the prescribed overvoltage, and obtaining a turn ON for protecting with a photocurrent. CONSTITUTION:A photothyristor 100 has an n type base layer 1, a p type base layer 2, a p type emitter layer 3, an n type emitter layer 4, an anode electrode 5, a cathode electrode 6 and p type base regions 20, 21 connected with nothing. When the thyristor 100 is set to a turn OFF state and the forward voltage is applied, a light L is emitted to the portion R between the regions 20 and 21. When the forward voltage exceeds the rated voltage and arrives at the protecting overvoltage, the layer 7 expands to the vicinity of the second p type base region 21, the light L is converted efficiently to the photocurrent, fed to a main thyristor region 300 to firing. Then main thyristor region is effectively turned ON, thereby performing the protecting operation without damage of the element.

Title: Machine cotton container
Inventor: MIYAMOTO TOSHIO
IPC: D05B43/00
Filed: 1990-03-02
Abstract: PURPOSE:To lower the bulk of a machine cotton container in a vertical direction and enable the storage of many containers stacked in a storage box such as a corrugated fiberboard box by so coupling a body for storing a bobbin and a cover as to be freely detachable and making adjustable the projection amount of the cover for the body. CONSTITUTION:A cover 4 so fitted to a body 1 as to be freely detachable is made integral with each other with an inverted F-type engagement groove 3 and an engagement piece 41. Consequently, the bulk of a machine cotton container when stored for non-use can be made lower than when used. It becomes possible, therefore, to contain relatively more containers in the same storage box, thereby enabling the reduction of storage space. In addition, each bobbin is free from contamination, because of storage in the container. Also, a thread delivery section mainly comprising a felt 6 and formed on the external edge of the cover 4 is integrated therewith. As a result, a stitching thread is smoothly paid out, even if there is a connection therein. According to the aforesaid construction, the container when stored can be lowered in bulk, together with the storage box thereof.

Filed: 1997-03-06
Abstract: PROBLEM TO BE SOLVED: To transform speech without deterioration by sequentially shifting a selection part according to an alteration rate of a sampling period and fetching a partial column from each selection part by making use of periodicity of an input speech. SOLUTION: Input speech picked up by a microphone 11 is sampled at a fixed sampling frequency by an A/D converter 12 and converted into a series of digital data. On the other hand, a transformation setting means 13 is set to a sampling transformation rate.

Title: Voltage drop detection circuit
Inventor: TANAGAWA KOUJI
IPC: G01R19/165
Filed: 1984-03-21
Abstract: PURPOSE:To make it possible to detect voltage drop determined by the change portion from the voltage of a power source, by simple constitution such that voltage drop of the power source is detected on the basis of voltage obtained by integrating the voltage of the power source. CONSTITUTION:When the voltage of a power source is applied to the voltage wire 1 of the power source, the voltage of the power source is integrated by an integrator circuit consisting of a diode 4, a resistor 5 and a capacitor 6. This integrated voltage is supplied to a reset terminal 22 and a logical circuit part 2 performs the automatic resetting to the initial state. When the voltage of the power source is abruptly lowered from a steady operation state, gate voltage becomes lower than the source voltage of a P channel MOS transistor 3 and, therefore, said MOS transistor 3 is brought to a continuity state. As a result, because voltage charged to the capacitor 6 is discharged through the MOS transistor 3 and a resistor 7 and voltage at both terminals of the resistor 7 are supplied to a control circuit 8 as a power source voltage drop signal, the logical circuit part 2 enters a power-down mode.

Title: Horn speaker
Inventor: SHINTAKU FUMIO
IPC: H04R9/00
Filed: 1986-03-12
Abstract: PURPOSE:To increase the output of a horn speaker, and to miniaturize a device, by abutting the cooling side of an electronic cooling element at the inner peripheral plane of the base of a diaphragm, providing a large number of radial grooves at the front plane of a center pole, controlling the heating of the center pole, cooling a movable coil compulsorily, and permitting a large current to be conducted. CONSTITUTION:Since a leakage magnetic flux is cut off by the oscillation of a movable coil 10 in the forward and backward direction, an eddy current in a direction to stop the oscillation of the movable coil 10 is conducted at the front plane of a center pole 6, and intends to heat the center pole 6. And since the large number of radial stripe grooves 7 are formed at the front plane of the center pole 6, those stripe grooves suppress the generation of the eddy current, thereby the heating of the center pole 6 is suppressed. Therefore, the movable coil 10 can be maintained at a comparatively low temperature, even when conduction through the coil continuous for a long time. Furthermore, in the horn speaker, by performing the conduction to an electronic cooling element 10 simultaneously with the conduction to the movable coil 10, and setting the contact plane with the diaphragm 8 of the electronic cooling element 10 at a low temperature, the movable coil 10 can be cooled.

Abstract: PURPOSE:To obtain an equalization LSI delaying a synchronizing signal by adjusting a delay in the synchronizing signal in matching with the delay due to waveform equalization in a video signal in a MUSE video signal receiver. CONSTITUTION:A synchronizing signal frame pulse, a line pulse are inputted to synchronizing signal delay circuits 400, 420 controlled by a video delay clock signal in an equalization LSI. Since the synchronizing signal is delayed in the synchronizing signal delay circuits 400, 420 by using a clock signal the same as that for the video signal, the phase between the video signal and the synchronizing signal outputted from the equalizing LSI is the same as that at the input to the equalizing LSI. Moreover, the video signal receiver of this invention is provided with post-stage circuits 28, 32 subject to timing control by using a delay synchronizing signal from the equalizing LSI whose timing is coincident with the video signal subject to equalizing processing.
