Title: Loudspeaker device
Inventor: NAKANO IKUHIDE
IPC: H04R1/02
Filed: 1995-02-06
Abstract: PURPOSE: To exclude vibration due to whizzing in a cabinet by blocking a sound radiated from the back face side of a loudspeaker unit to a rear chamber to intrude into a front chamber and to prevent the sound quality of a reproducing sound from deteriorating by employing such constitution that the rear chamber divided by a partition is formed in sealed structure. CONSTITUTION: When an acoustic signal is inputted from input terminals 13, 14 to a voice coil via extension lines 15, 16, the diaphragm 17 of the loudspeaker unit 11 mounted on the partition 2 vibrates. The sound from the front side of the unit 11 is radiated to the outside of the front of the cabinet 1 via an external duct 6. The sound radiating the back face side of the unit 11 is radiated on a sealed rear chamber 4, and it is transmitted to the diaphragm 19 of an internal passive radiator 18, which vibrates the diaphragm 19. The sound radiated on the front of the diaphragm 19 is superimposed on the sound from the front side of the unit 11, and radiated to the outside of the front of the cabinet 1 via the duct 6.  In such a way, it is possible to enhance the sound radiated to the outside of the front of the cabinet 1, which enables this device to be suitable for, especially a low frequency band component.

Filed: 1989-01-27
Abstract: PURPOSE:To improve the S/N, frequency characteristic and sensitivity by comparing an output voltage of an output signal from a sample-and-hold circuit with a reference voltage for a period sufficiently longer than a clock period of a CCD output signal and feeding back the comparison output to a connecting point between a capacitor and the said circuit. CONSTITUTION:Since there is dispersion in an offset level of sample-and-hold circuits 4, 5 and 6, current output type comparators 8, 9 are provided to correct the level error. The comparators 8, 9 input output voltages of output signals VP2, VD1 to inverting input terminals 8a, 9a respectively and a reference voltage Vref from a constant voltage source 10 is inputted to noninverting input terminals 8b, 9b. Then the output voltage and the reference voltage are compared for a period sufficiently longer than the clock period of the CCD output signal and a difference of both the voltages is used as a current output to be fed back to a connecting point between the capacitor and the sample-and-hold circuits 2, 4 and the connecting point between the capacitor and the sample-and- hold circuits 3, 5. Thus, the S/N and the frequency characteristic are improved and since no APL fluctuation takes place, high sensitivity processing is attained.

Title: Scanning electron microscope and similar device
Inventor: KURODA KATSUHIRO
IPC: H01J37/244
Filed: 1984-02-06
Abstract: PURPOSE:To enable images to be observed with an ultrahigh resolution by performing image display by taking out only secondary electrons having a specified energy width through a band pass filter consisting of the first to the third grids. CONSTITUTION:Electron rays of a scanning electron microscope are converged with a lens 1 before being irradiated upon a sample 2 and two-dimensionally scanned by a deflector 3. The thus produced secondary electrons are then accelerated by an electric potential (V1) applied to a first grid 4 before only secondary electrons with a special energy are passed through a second grid 5 to which a control electric potential (V21) is applied. The secondary electrons passing through the second grid 5 are accelerated by a third grid 6 and pass through the third grid 6 before being detected with a detector 7. The electric potentials (V21) and (V22) can be interchangeably applied to the second grid 5. Thus produced signals are subjected to subtraction in a subtracting circuit 9 so as to perform display on a picture tube 10. As a result, an SEM image can be produced only with secondary electrons of a specified energy, thereby improving the resolution of the scanning electron microscope.

Title: Bar code printer
Inventor: OONUMA TERUYUKI
IPC: G11B5/02
Filed: 1983-02-07
Abstract: PURPOSE:To easily record various widths of bar codes by a simple mechanism in which the width of magnetic latent images formed in a thermo-magnetic recorder by a heat input means is partly erased by selective operations and visualized magnetic latent images by a color magnetic ink are fixed to the thermo- magnetic recorder as such or transferred to a transfer medium and fixed. CONSTITUTION:The magnetization direction of a thermo-magnetic recorder 1 is unformly arranged by a magnet 2, a bar code pattern signal is given to a thermal head 3 under the influence of the magnetism of a magnet 4, and the inversion of the magnetization of a portion subject to the heating of a heating element 3a is made to form a magnetic latent image. In case where necessary image width of bar code to be obtained is maximum, a magnetic latent image in the necessary maximum width is formed by the thermal head 3, and the magnetic head 5 is therefore retracted to the outside of the magnetic latent image region. The magnetic latent image is thus developed as such by a color magnetic ink in the development section 6 without influence of the magnetic head 5 and visualized. On the other hand, in case where the necessary image width of the code is smaller than maximum, the magnetic heat 5 goes forward in a necessary amount into the magnetic latent image region by a drive means.

Abstract: PURPOSE:To decrease the distance between a track to be used exclusively for reproduction and a rewritable track to about 1/2 of 1.6mum, i.e., 0.8mum and to make twice higher the recording capacity over the entire part of a disk by disposing both tracks so as to adjoin alternately to each other. CONSTITUTION:The track 1 to be used exclusively for reproduction is the same as the track of the conventional optical disk consisting of pit trains to be used exclusively for reproduction. For example, an amorphous magnetic film 3 consisting of a rare earth metal-transition metal alloy which permits photomagnetic recording is used as the recording medium for the erasable tracks 2. Such optical disk can be manufactured by forming the pits for the part to be used exclusively for reproduction by a press method in the same manner as in the conventional method then depositing the film 3 thereon by a sputtering method, vapor deposition method, etc. The film 3 acts also as a reflection film of the track part to be used exclusively for reproduction.

Title: Method and system for memorizing and retrieving graphic image
Inventor: ANDAASU BII BINBAAGU
IPC: G06F17/30
Filed: 1987-01-30
Abstract: Automation of graph image storage and retrieval in a multi-user system having a central processing facility with performing processes that create and translate graphical image representations in varying levels of readable expression. The created, translated representations are stored in system storage in the form of graph image files. The invention is expressed as a method that tabularizes stored graph image representations by table entries, each identifying a specific graph and including a listing of the corresponding graph image files. When a user of the system identifies a graph by table entry and specifies a machine output or modification function to be performed on the identified graph, the tabularized entries are searched to locate an entry for the identified graph. Once the correct table entry is found, the graph file listing is searched according to a user-specified representation preference ordering to determine whether a specified output function can be performed by any of the stored graph image files produced for the identified graph, If a match is found between one of the representations stored for the graph and one of the representations in the preference ordering, the matched file is retrieved from storage and translated to the level required for the function. The translated file is then dispatched to the user for performance of the function.
