Title: Microphone
Inventor: MATSUMOTO MICHIO
IPC: H04R3/00
Filed: 1984-06-13
Abstract: PURPOSE:To improve the convenience of use without increasing the size of a camera by containing a bidirecionally directive microphone so as to allow its center axis to be orthogonal to a center axis of a case. CONSTITUTION:The direction of a unidirectional microphone 1' is a direction where the center axis is coincident with the center axis of the case 2. Further, the direction of the bidirectional microphone 3' is a direction where its center axis is orthogonal to the center axis of the case 2. Since the center axis of the case 2 is directed toward the direction of a sound source, the case is fitted in parallel with a video camera thereby allowing ease of use. Phase shifters 10-13 are to correct the difference of the distance between the sound source and the microphone 3' and the distance between the microphone 1' and the sound source so as to prevent the reduction in the stereo phonic effect depending on the difference of the distance. Moreover, although the phase characteristic due to path difference depends on a frequency, the phase characteristic of the phase shifters is changed by the frequency accordingly.

Title: Switching regulator
Inventor: KURUMA AKIO
IPC: H02M3/28
Filed: 1984-06-12
Abstract: PURPOSE:To stably use a switching regulator by drooping the output of the regulator when the overcurrent state of the output current of the regulator is detected. CONSTITUTION:When the output current of a switching regulator 16 becomes an overcurrent state, a comparator 8 starts switching operation in the pulse width proportional to the increase in the output current. The charge of a capacitor 12 is discharged or charged in response to the period that the output of the comparator 8 becomes ''1'' or ''0''. Thus, the both end voltage of the capacitor 12 is sufficiently smoothed to decrease at a suitable responding speed depending upon the current I0. As a result, the output voltage V0 of the regulator 16 is drooped. Accordingly, it does not respond to the cause of the erroneous operation due to the electrostatic noise, but the regulator can be stably used.

Title: Base driving device of transistor inverter
Inventor: YUZURIHARA ITSUO
IPC: H03K17/61
Filed: 1983-07-04
Abstract: PURPOSE:To make a power source for a reverse bias unnecessary and enhance the efficiency of a reverse bias current when a reverse bias supplying transistor TR is turned on, by providing two FETs, which supply a forward bias and the reverse bias, and a diode which regenerates an exciting energy as a power source. CONSTITUTION:When an operation switch 1 is turned on, the outputs of gates 3a and 3b transmit square wave voltages to the outputs of transformers 12 and 12b through FETs 5a and 5b. Rectified outputs of transformer outputs are applied to an FET 5e as a forward bias, and a forward bias current is supplied to a TR 10. In this state, the exciting energy stored in the on-cycle section of transformers is regenerated as a power source Vd through a diode 11a or 11b in the off-cycle section. When the switch 1 is turned off, an FET 5f is turned on, and the exciting energy of transformers 12a and 12b passes a diode 11g or 11h and the FET 5f to supply a large base reverse bias current to the TR10. All of the exciting energy is supplied to the TR10 even if the FET 5e is turned on at this time. After sweeping of the stored carrier of the TR10 is terminated, the re maining exciting energy is regenerated as the power source Vd through the diode 11a or 11b.

IPC: G06T7/00
Filed: 1996-05-16
Abstract: PROBLEM TO BE SOLVED: To secure an operation error that has no practical problem and also to increase the operation speed by giving the initial value to every section of a θ operation area to calculate the ρ value for formation of a Hough function curve and performing the simultaneous and parallel operations at the individual recurrence operation parts to decide the p value of the Hough function curve part of every section. SOLUTION: The given initial value (x, y) is directly inputted to a counterclockwise recurrence operation part 3a, and the complement of 2 of (x) is produced and the initial value (y, -x) is given to a clockwise recurrence operation part 3b. Then a switch 30 is switched toward the operation side and ρ1.1 , ρ1.2 , ρ2.1 and ρ2.2 are generated in parallel to each other by the clock pulse input. The clock pulse is supplied to a frequency accumulation addition part 35 of a θ-ρ memory, and +1 is given to the address contents. Then a θ operation area is divided into four sections to perform a 4-element parallel operation. Therefore, the cumulative error of the end value is reduced in every section of the θoperation area despite application of a recurrence formula. Thus, no practical problem is caused.

Title: Vibrator
Inventor: KAKIUCHI YOSHIHIKO
IPC: B06B1/04
Filed: 1992-05-14
Abstract: PURPOSE:To ensure the holding of the state when a sound guide is formed and to prevent the reduction in the body sensing vibration by providing a strength to a hollow member to keep a shaping form of the sound guide against an external force exerted under the usual operating environment. CONSTITUTION:A shape of cross section, type of material or a thickness or the like is set to a hollow member 1 made of a flexible material having a continuous sound guide path in its inside to keep the forming shape of the sound guide path against an external force (e.g. weight exerted when a person sits down a chair or the like) exerted at least under a usual operating environment. Then an input cord 2 is used to deliver an electroacoustic signal to a speaker being a built-in electroacoustic transducer means in the sound guide path. Thus, the state of forming the sound guide path is surely kept by the strength of the hollow member 1 itself without intake of a gas (air) to swell the hollow member 1.

Title: Ground inspection system
Inventor: ITOU YUKIO
IPC: G01R31/02
Filed: 1981-08-04
Abstract: PURPOSE:To make consideration for a driving system unnecessary, and to execute a ground inspection of line and row driving paths of a load driving matrix by the same inspection circuit, by placing a switch between a load driving path and a ground inspecting circuit, and operating it by a prescribed timing. CONSTITUTION:A switch Z is installed between a multiple inspecting point D of line and row driving paths through turn-round preventing diodes Dao-Dal and Dbo-Dbl, and a ground inspecting circuit A. When this switch Z is closed at the timing before matrix loads Loo-Llo are driven through line and row driving devices Xo-Xl and Yo-Yl, the circuit A is connected to the line and row driving paths, and a ground inspection is executed. Subsequently, immediately before the driving devices Xo-Xl and Yo-Yl start the operation, the switch Z is opened. Accordingly, consideration for the driving system is uncessary, and the ground inspection of the line and row driving paths can be executed independently from driving the line and rows, and also by the same inspecting circuit against the line and row.

Title: Stair
Inventor: YAGYU KENTARO
IPC: E04F11/02
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To reduce the danger of falling by providing an inclination such that the column side forming the center of a curvature is high and the opposite side is low on the tread of the curved part of a broken stair or a spiral stair way. SOLUTION: Treads 1-6 to be arranged in step form are arranged around a column P with the direction being changed by a certain angle to form the curved part of a broken stair. The surfaces of the treads 1-6 in the curved part of the broken stair are inclined so that they are higher on the column P side by a height H than a wall R side, and horizontally extended in the ascending and descending direction of the stain. The inclination of surface of the treads 1-6 is set to 0.5/100 to 2/100, and the curved part is present only in the middle of the stair. Thus, a person going up and down on the tread surfaces naturally passes the wall side opposite to the column, and hardly fall from the stair by slippage.

Title: Adsorption travelling device
Inventor: HIKITA YOSHIHIKO
IPC: B63B59/10
Filed: 1977-10-14
Abstract: PURPOSE: To eliminate hazardous work, by performing relative movement for restricting the mutual motion of sliding portion materials by inserting the sliding portion materials, which both end portions mount bodies to be adsorbed, into alternative supporting portions on crossing sliding-free shapes and by alternatively adsorbing the bodies to be adsorbed of the sliding portion materials.  
     CONSTITUTION: Electromagnets 2 in bodies 3a to be adsorbed are excited and adsorbed to a ferromagnetic wall surface 11, and electromagnets 2 in bodies 3b to be adsorbed are demagnetized. When turning an air motor 7, a crossing supporting portion 4 moves along a sliding portion material 1a through a pinion 8 and a rack 6 while sliding portion materials 1b slide in a sliding guide 5b by the action of a pin 10 and a guide 9 and stop at a chain line location. When the electromagnets 2 in the bodies 3b to be adsorbed are excited, the electromagnets 2 in the bodies 3a to be adsorbed are demagnetized and the air motor 7 is driven, the sliding portion material 1a moves in the arrow head B direction. The travelling direction  mounted to one side of sliding portion materials intermittently travels in the arrow  head B direction by repeating this operation, thus performing necessary work. Consequently, hazardous work can be eliminated

Title: Video tape recorder
Inventor: MIURA KUNIAKI
IPC: H04N5/7826
Filed: 1985-06-07
Abstract: PURPOSE:To record a high speed video signal having the number of fields per second (n) times as many as a standard video signal without providing a special means such as increasing the number of rotating head by changing over a feed speed of a magnetic tape and a rotating speed of the rotating head to (n) times as fast as a standard speed. CONSTITUTION:A magnetic tape 2 is herically scanned by rotating heads A, B to record and reproduce a video signal. In such a video tape recorder, when a high speed video signal having the number of fields (n) times as many as a standard diveo signal is recorded, the rotating speed of the rotating heads A, B and a feed speed of the magnetic tape 2 are changed over to (n) times as fast as a standard speed and these relative speed ratio is made equal to the case when the standard video signal is recorded. Thereby, a recording track pattern of the high speed video signal formed on the magnetic tape is the same as the recording track pattern of the standard video signal and the recording track of the high speed video signal can be easily reproduced at a standard speed.

Title: Resonance optical structure photoelectric detector having diffraction grating
Inventor: GIDON SERGE
IPC: H01L31/0232
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of a working area in order to reduce the noise within a ditector device by constituting an electromagnetic wave detecting device on the basis of a direct gap photoelectric detecting material. SOLUTION: A base 2 is formed of a material consisting of, for example, CdTe, and having transmissivity to at least one wavelength of a radiation 3 to be detected. The radiation 3 reaches a detecting layer 4 through the base 2. The detecting layer 4 is formed of, for example, a CdHgTe layer provided on the base 2. The detecting layer 4 is generally formed of a direct gap photoelectric detecting material. The detecting layer 4 is situated between the base 2 and a diffraction grating 6. In this structure, an optical guide formed of the diffraction grating and the layer 4 of the photoelectric material constitutes a resonance structure. The diffraction grating 6 diffracts an electromagnetic wave within the plane formed by the layer of the photoelectric material.  Therefore, the thickness of this layer is reduced. the dark current of the detector can be thus reduced without losing a useful signal.

Title: Electromagnetic driving shutter
Inventor: FUJINO MASAHISA
IPC: G03B9/36
Filed: 1984-06-14
Abstract: PURPOSE:To improve the accuracy of a shutter by disengaging a shutter blade driving member held at a travelling completing position simultaneously with film winding and restoring the driving member to a travelling start position by inertia. CONSTITUTION:When a winding interlocking shaft 48 interlocking with a winding means starts to rotate, a restoration lever 40 is rotated around a shaft 49a in the counterclockwise direction to press a suspension lever 28 in the arrow direction. At that time, its right end part 28c presses a pin 7a on a front blade driving lever 7 and a notched edge 28b on an intermediate part presses a pin 5a on a back blade driving lever 5. Consequently, a front blade driving pin 6 and a back blade driving pin 4 get over the bending parts 36a, 34a of holding springs 36, 34 and the holding at the travelling completing positions is released. When a restoration level 40 is rotated continuously, the driving levers 7, 5 are rapidly pressed to their travelling start positions and immediately restored to the travelling start positions by inertia and restoration springs 44, 45. Thus, the shutter accuracy can be improved.

Filed: 1990-05-11
Abstract: PURPOSE:To obtain a detecting device capable of rapidly detecting the abnormality of a rotor by providing a discrimination means for comparing and discriminating between a vibration level calculated by an arithmetic means and a vibration level stored by a storage means and a means for displaying the abnormality of vibration of the rotor when the vibration level rises. CONSTITUTION:Dummy images 12a and 12b in which scale is provided at regular intervals are printed along a rotating direction on both bridge parts on the outer peripheral surface of a photosensitive drum 12d, and the detection signals of optical sensors 2a and 2b which optically detect the patterns of the images 12a and 12b are stored in a RAM 51. The stored data is individually Fourier- transformed by the arithmetic means 52 so as to respectively calculate the vibration level of every frequency. When the discrimination means 53 discriminates that the signal of the optical sensor 2a exceeds a threshold Vo, the display of abnormality is executed by the display means 6, and the driving of the photosensitive drum 12d or the driving of an entire copying machine is stopped by a driving stop means 7. Thus, the detecting device capable of rapidly detecting the abnormal rotation of the rotor is obtained.
