Title: Interval converting device
Inventor: NIIHARA TOSHIKO
IPC: G10L21/04
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To convert the interval of an individual's voice without deterioration in sound quality so that features of the individual's voice are left. SOLUTION: A digital input voice signal is cut by a filter 1 into frames of a specific time and a pitch frequency extracting means 2 extracts the pitch frequency of the voice signal outputted from this filter 1. The voice signal outputted from the filter 1 is supplied to an FFT(fast Fourier transforming means) circuit 3 as well and converted from a time-area signal from a frequency-are signal, whose entire frequency band is shifted by a frequency shift means 4 to a higher or lower frequency side. Then a harmonic structure operating means 5 increases or decreases the level of harmonic components of the pitch frequency of the voice signal having its entire frequency band shifted by the frequency shift means 4 from the pitch frequency extracted by the pitch frequency extracting means 2.  Then an IFFT(inverse fast Fourier transforming means) circuit 6 converts the signal into a time-area signal, which is outputted.

Title: Receiver for direct spread spectrum signal
Inventor: FUREDEI NEEZERU
IPC: H04B1/707
Filed: 1991-11-15
Abstract: PURPOSE: To attain adaptive reception of digital data for mobile communication by allowing an inverse filter to be used in place of a matching filter for responding to a prescribed pulse series itself by means of a pure Kronecker δsymbol series. CONSTITUTION: An approximated inverse filter is provided for detecting a symbol Bm, and in the case of application by a prescribed pulse series S[.]5 itself, a Kronecker δ symbol series is used for an approximate reply as an output series. That is, in order to detect data, a DSSS signal is not processed by a matching filter but by an inverse filter 12. The matching filter is a superior filter with respect to a maximum S/N but the inverse filter 12 is markedly superior in a peak to off-peak ratio (a ratio of a maximum amplitude of a filtered DSSS signal to a maximum secondary amplitude). Thus a peak of the pulse at an output terminal of the filter, including transmitted data, is surely and simply detected. Thus, the receiver is suitable for receiving digital data in a mobile communication channel.

Title: Automatic demagnetizing circuit of color cathode-ray tube display
Inventor: IMAI KENICHI
IPC: H04N9/29
Filed: 1991-12-26
Abstract: PURPOSE:To provide a demagnetizing circuit which does not perform demagnetization when the shadow mask of a color cathode-ray tube is in a non-magnetized state but only when affected by geomagnetism (in a magnetized state) by providing circuits for setting azimuths, for detecting azimuth differences and for comparing azimuths, etc. CONSTITUTION:A storage circuit 1 stores an azimuth signal produced when demagnetization is performed at the application of an initially set signal or a load signal. An azimuth difference circuit 2 detects the difference between the stored azimuth signal and an azimuth signal being actually sent from azimuth detection means; i.e., the circuit 2 detects how much the azimuth detected at the demagnetization deviates from the current azimuth. When the detected azimuth difference exceeds a value preset to an angle setting circuit 3, a comparison circuit 4 performs judgement to actuate a demagnetizing pulse generating circuit 5 and a demagnetizing circuit 6 performs demagnetization. Simultaneously the comparison circuit 4 sends a load signal to the storage circuit 1 and the storage circuit 1 eliminates the previous azimuth signal and stores the new azimuth signal. As a result, the screen of a color cathode-ray tube can be protected from adverse effects of direction changes.

Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To save a plane space of a movement and reduce the number of part items. SOLUTION: In a power reserve mechanism 100, a planet wheel 3 is united and integrated at a lower part of a movement barrel 1. Since the arrangement makes it unnecessary to arrange the planet wheel 3 in the circumference of the movement barrel 1, a plane space of a movement is saved. Although a reception part is necessitated if the planet wheel is set separately, the power reserve mechanism 100 eliminates the part, thereby reducing the number of part items. The power recerve mechanism 100 can be assembled simply.

IPC: G01L23/18
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a cylinder internal pressure reading device which does not need to use expensive circuit elements with high processing speeds in an engine control circuit even if a sampling period for reading cylinder internal pressure detection signals is reduced because of a rise in engine speed. SOLUTION: An engine speed is read (step 1), and whether or not the engine speed Ne is not more than 3000 rpm is determined (step S2). If Ne<=3000 rpm, cylinder internal pressure Pi is read (step S3). If Ne>3000 rpm, whether or not the engine speed Ne is not more than 6000 rpm is determined (step S4). If Ne Sh6000 rpm, whether or not the reading of the previous cylinder internal pressure Pi has been stopped is determined (step S5). When the reading of the previous cylinder internal pressure Pi has been stopped, the step S3 is started to read the cylinder internal pressure Pi, whereas when the previous cylinder internal pressure Pi has been read, main action is directly terminated. If Ne>6000 rpm, whether or not the reading of the cylinder internal pressure Pi has been stopped twice in succession is determined (step S6).  If the reading of the cylinder internal pressure Pi has been stopped twice in succession, the step S3 is started to read the cylinder internal pressure Pi, whereas when the reading of the cylinder internal pressure Pi has not been stopped twice in succession, the main action is directly terminated. After the execution of the step S3. the operation of computing the controlled value of the engine is performed using the cylinder internal pressure Pi read, to control the controlled value (step S7).

Abstract: PROBLEM TO BE SOLVED: To avoid a bottleneck of a practical maximum transfer capacity of a local bus by communicating information by using the other PC card that is connected to an information processor and a 2nd information communicating means. SOLUTION: An SCS12 controller 205 reads data from a file in DVD-ROM 203 and sends the data to a card bus controller 204. Here, when it is instructed to communicate by using an optical communication transmission path 214 between PC cards 201 and 202 without using a card bus 13 according to an instruction group that is sent from a host CPU, the controller 204 sends the data that is received from the DVD-ROM 203 to a transmission controller 206. The controller 206 performs error correction coding of the data from the DVD-ROM 203, drives an optical transmission module 207 based on the data and sends information to the other PC card 202.

SOLUTION: A lower side receiving means 16 for receiving lower sides 34 of documents 10 or the like to coincide with the position of lower sides 42 of a cover 12 as vertical sides 30 of the documents 10 or the like are applied to a boring depth setting piece 32 of a boring machine 15 is installed on the boring machine 15, holes are bored close to the vertical sides 30 in the documents 10 or the like by the boring machine 15 as it is applied to the boring depth setting piece 32 of the boring machine 15 while a position of the lower sides 34 of the documents 10 or the like are set to the lower side receiving means 16, and the documents 10 are bound in the cover 12 in this method of binding the documents 10 or the like.  Since the lower sides 34 of the documents 10 are arranged to the lower sides 42 of the cover 12, weight of the documents 10 or the like can be directly applied to a supporting surface when the cover 12 is put to stand. Punching holes 14 can be formed arranged only by arranging lower sides even when documents 10 of various sizes are mixed.
